Definitions
- the present invention relates to a release agent composition, and more particularly to a mold release agent composition suitable for use in molding a molded article such as a synthetic resin or a synthetic rubber.
- a release agent is applied to the inner surface of the mold.
- a wax-based release agent such as paraffin wax, higher fatty acid ester wax, or polyethylene wax is known. These wax-based release agents are widely used because they are available at low cost and the surface condition of the obtained molded product is good.
- wax-based mold release agents are inferior in mold-releasing force, apply thickly to the molding dies, especially when molding a molded body using a material with strong adhesion such as epoxy resin or urethane resin. Otherwise, a sufficient releasing effect cannot be obtained, and as a result, there is a problem that the inside of the molding die is contaminated as the number of molding steps increases. This problem also adversely affects the dimensional accuracy of the compact.
- wax-based release agent since the wax-based release agent has poor adhesion to the molding die, it easily transfers to the surface of the molded product, and has a problem that the release effect is inferior. This problem leads to the problem that a release agent must be formed for each molding step. Furthermore, since wax-based release agents are transferred to the surface of the molded body in large quantities when the molded body is released from the molding die, it is inferior in secondary processing (printing and coating) on the molded body surface. Have a problem.
- a fluorine-based release agent [a copolymer of a polyfluoroalkyl ester of (meth) acrylic acid and a substituted vinyl compound] is known (Japanese Patent Application Laid-open No. (See Japanese Patent Application Laid-Open No. 59-101319 and Japanese Patent Application Laid-Open No. Sho 60-255504).
- this fluorine-based release agent has excellent release force, a sufficient release effect can be obtained only by forming it thinly.
- the adhesiveness to the molding die is excellent as compared with the above-mentioned wax-based release agent, so that the durability of the release effect is also excellent.
- Japanese Patent Publication No. 3-8.245 discloses a copolymer obtained by polymerizing a perfluoroalkyl group-containing vinyl monomer, a phosphoric acid-containing vinyl monomer and a hydrocarbon vinyl monomer.
- a release agent comprising coalescing is disclosed.
- the release agent contains a large amount of phosphoric acid, the curing reaction is hindered with resins and rubbers, especially urethane resins, that react during the molding process. Poor surface appearance occurs.
- the reaction between the release agent and the molded body causes a problem of mold contamination.
- Japanese Patent Publication No. 59-32515 also discloses a release agent obtained by blending a silicone resin with a polyfluoroalkyl group-containing copolymer.
- a silicone resin with a polyfluoroalkyl group-containing copolymer.
- stickiness occurs on the surface of the molded product, resulting in poor secondary workability.
- Silicone also causes pollution in the work environment. Silicone mold release agents have a problem that when transferred to the surface of the molded body, the surface of the molded body is sticky and the secondary workability on the surface of the molded body is poor.
- An object of the present invention is to solve the above-mentioned problems, to provide a mold release agent having good secondary workability on a surface of a molded article and excellent mold release properties.
- the gist of the present invention is as follows: (i) a polyfluoroalkyl acrylate or methacrylic acid ester having 1 to 20 carbon atoms and a vinyl compound having an alkyl group having 8 to 30 carbon atoms. 10 to 95% by weight of a copolymer; and ii) 90 to 5% by weight of a silicone.
- a polyfluoroalkyl acrylate or methacrylic acid ester having 1 to 20 carbon atoms and a vinyl compound having an alkyl group having 8 to 30 carbon atoms. 10 to 95% by weight of a copolymer; and ii) 90 to 5% by weight of a silicone.
- both components are not compatible with each other, so that the release agent composition is divided into a layer mainly containing the ⁇ component and a layer mainly containing the ⁇ component.
- the A component plays a role of adhesion to the molding die, and the B component mainly plays the effect of releasing from the molded product.
- the vinyl compound having an alkyl group having 8 to 30 carbon atoms copolymerized in the component A also has an effect of keeping the component B together by the long-chain alkyl group.
- a layer mainly composed of the component A is formed on the molding die side
- a layer mainly composed of the component B is formed on the molded body side.
- the component A When releasing the molded body, the component A is formed on the surface of the molded body.
- the main layer does not transfer, and the layer mainly containing the B component is broken, so that it is easily released.
- the amount of the layer mainly composed of the component B that is ruptured and transferred is smaller than the amount transferred when the silicone-based release agent is used alone. It does not have stickiness or adversely affect the formability of the molded product surface.
- Polyfluoroalkyl acrylates preferably used in the present invention
- examples of steles or methacrylates have the general formula:
- R 1 is a hydrogen atom or a methyl group
- R 2 is a linear or branched alkylene group having 1 to 10 carbon atoms, one S0 2 N (R 3 ) R 4 — group, CH 2 CH (OR 5 ) CH 2 — group (where R 3 is an alkyl group having 10 to 10 carbon atoms, and R 4 is a linear or branched alkylene having 1 to 10 carbon atoms)
- R 5 is a hydrogen atom or an acyl group having 1 to 10 carbon atoms: :
- Rf represents a linear or branched polyfluoroalkyl group having 1 to 20 carbon atoms .
- Examples of preferred compounds as a vinyl compound having an alkyl group having 8 to 30 carbon atoms are represented by the following general formula:
- R 1 is as defined above.
- R 6 represents an alkyl group, an aralkyl group, an alkenyl group, an alkyl group, an aralkyl group, an alkenyl group, or a substituted with a hydroxyl group or a carboxyl group having 8 to 30 carbon atoms.
- the proportion of the polyfluoroalkyl acrylate or methacrylate in the copolymer is preferably from 20% by weight to 85% by weight, more preferably from 30% by weight to 70% by weight. If the content is less than 20% by weight, a sufficient effect cannot be obtained and mold stains increase. On the other hand, if it exceeds 85% by weight, the releasability will be poor.
- the polyfluoroalkyl group has 1 to 20, preferably 5 to 20, and more preferably 8 to 20 carbon atoms. If it is longer than this, it is economically inappropriate.
- the alkyl group of the vinyl compound having an alkyl group has 8 to 30 carbon atoms, preferably 14 to 30 carbon atoms. If the number of carbon atoms is less than 8, sufficient mold releasability cannot be obtained. The effect of keeping the resin is weakened, and the transfer of silicone to the molded body increases, so that the secondary workability deteriorates.
- copolymers are used to improve the film-forming properties and durability of coating films, in addition to polyfluoroalkyl acrylates or methyl acrylates and vinyl compounds having an alkyl group having 8 to 30 carbon atoms.
- another vinyl compound for example, butyl methacrylate, ethyl methacrylate, glycidyl methacrylate, 2-hydroxymethacrylate, styrene, cyclohexyl methacrylate and the like may be copolymerized.
- the ratio of these other vinyl compounds Is preferably 10% by weight or less in the copolymer. If it is more than this, it will adversely affect the releasability.
- various polymerization reaction systems and conditions can be arbitrarily selected, and various polymerization systems such as bulk polymerization, solution polymerization, suspension polymerization, emulsion polymerization, and radiation polymerization can be used. Either can be adopted.
- Silicones that may be used in the present invention is, for example, dimethylpolysiloxane oil, alkyl methyl polysiloxanes oil, S i0 2 and (CH 3) 3 S i0 silicone resin consisting of 1/2.
- the copolymer and the silicone have a component ratio of 10 to 95% by weight of the copolymer and 90 to 5% by weight of the silicone.
- the combined amount is 10 to 90% by weight, the silicone is 90 to 10% by weight, more preferably the copolymer is 20 to 7% by weight, and the silicone is 80 to 30% by weight.
- the amount of the polyfluoroalkyl group-containing polymer in the release agent composition is increased, the releasability is adversely affected. The amount is limited to 0.1 to 10% by weight of the whole.
- the polyfluoroalkyl group-containing copolymer contains a vinyl aldehyde compound having an alkyl group having 8 to 30 carbon atoms, it has an adverse effect on the releasability.
- the content is 10% by weight or more, the amount of silicone can be relatively reduced, which has a favorable effect on the stickiness of the molded body surface and the secondary workability.
- the release agent composition of the present invention When applying the release agent composition of the present invention to a molding die, any application method such as brush painting, dip coating, and spray coating is possible.
