Environment friendly adhesive without tribenzene
Technical field
The present invention relates to a kind of tackiness agent.
Background technology
Tackiness agent uses quite extensive in life, like footwear, tire etc.Existing tackiness agent mainly adopts X 050, tackifying resin etc. to process solvent; Be used for the tackiness agent (being tackiness agent (promptly yellow the paste)) in the shoemaking; As application number be 88105902, the applying date is that May 18, denomination of invention in 1988 are multifunctional adhesive for shoes, the patented claim in open/December 6 1989 day for announcing; It is that graft reaction mixture with vinyl acetate and TEB 3K and X 050 is a base-material, cooperates specific tackifying resin to process.The formula constituent of this tackiness agent (by weight) is: the graft reaction mixture that adhesive purpose chloroprene rubber and vinyl acetate and TEB 3K generate; 100 parts of tackifying resins; 3-10 parts of optimum formula components are: the graft reaction mixture that adhesive purpose chloroprene rubber and vinyl acetate and TEB 3K generate; 100 parts of tackifying resins, 4-6 parts.And existing oil price is constantly soaring, and the raw materials cost of producing organic solvent also increases much, and very strong moment corrodibility is much arranged, and also has pollution hidden trouble.
Summary of the invention
The objective of the invention is in order to solve above-mentioned deficiency, and a kind of environmental protection that has is provided, the environment friendly adhesive without tribenzene that bonding force is strong.
The technical solution that the present invention adopts in order to reach above-mentioned effect is following:
The production formula of this environment friendly adhesive without tribenzene (promptly yellow the paste); It is characterized in that; It constitutes (weight ratio) by following set of dispense ratio, methylcarbonate 10-30%, butanone 10-25%, acetone 1-15%, vinyl acetic monomer 1-15%, 3L tree elastomer 10-15%, rosin 10-20%.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
The solvent body that product of the present invention uses belongs to real no triphen environmental protection system, and use range is wide, uses tree elastomer and natural rosin resins, and production cost is low, and excellent generalization values is arranged.
Embodiment
This environment friendly adhesive without tribenzene (promptly yellow the paste) constitutes (weight ratio) by following set of dispense ratio, methylcarbonate-30%, butanone-20%, acetone-15%, vinyl acetic monomer-15%, 3L tree elastomer-12%, rosin-18%.
Of the present invention dose is to use tree elastomer to replace general X 050; Use natural rosin resins to prepare the tackiness agent (promptly yellow the paste) that is mainly used in shoemaking, solved a difficult problem because of the high production organic solvent adhesive starting material aspect in short supply that causes of crude oil price as tackifying resin.
Product of the present invention often by the footwear industry be used for EVA/EVA, the end, foam compound, climb group etc., probably about 4500cps/30 ℃, solid content is near 30% for viscosity.
Product of the present invention is having difference in essence with traditions of the past product cryogenic vulcanization tyre patching rubber material, glue for repairing tyre etc. aspect the collocation of organic solvent and the environment protection, and the scope of application is more extensive.
