Description
Technical field
The present invention relates to a kind of hot melt adhesive coating film composition and method of making the same, belong to the high molecular film material technical field.
Background technology
Usually hot melt adhesive is solid-state under room temperature state, offers the client with the form of micelle or blob of viscose and uses.The hot melt adhesive that pressure-sensitive is arranged generally uses the separate-type paper packing, prevents the adhesion between the blob of viscose, to make things convenient for the packing of product, stores and transportation.Separate-type paper packing hot-fusible tackiness agent owing to itself contain separated type material, has certain influence to the tackiness agent performance, moreover in client's use, the separate-type paper of blob of viscose need be peeled off, and expends man-hour, and efficient is lower.Simultaneously, separate-type paper is inconvenient to reclaim use, does not meet environmental requirement.
For providing tack-free to the client or being not easy the hot melt adhesive of adhesion, its advantage is very tangible.Before, the use of technology aspect the hot melt adhesive packing arranged, but the compatibility problem between coating film and the hot melt adhesive needs also to improve.Directly will there be the hot melt adhesive of coating film material to drop into the melten gel groove, because consistency has been accumulated a large amount of mould materials in the process of life-time service, to problems such as melten gel groove and applying glue equipment result in blockage.In addition, the job parameter of different coating film materials is variant, and is very big to different automatic packaging line adaptability difference.Product of the present invention is far built automatic packaging line with method and is used, and the coating film raw material of import substitution reduces packing cost, solves the problem of coating film and machine coupling and the problem of coating film and hot melt adhesive consistency simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of hot melt adhesive coating film composition and preparation method thereof, be used for solving current import coating film material cost height, it is poor that coating film material and method are far built the matching of automatic packaging line, and the compatibility problem between coating film material and the hot melt adhesive.
According to technical scheme provided by the invention, a kind of hot melt adhesive coating film composition, it is as follows to fill a prescription by weight: main polymer 50-80 part, wax 15-30 part, tackifying resin 20-40 part, oxidation inhibitor 0.3-1 part, slipping agent 0.1-0.5 part;
Described main polymer is SEBS, it is the styrene-ethylene-butylene-styrene segmented copolymer, SEPS, it is styrene-ethylene-propylene-styrene segmented copolymer, Low Density Polyethylene, polypropylene, the mixture of one or more materials in ethylene-vinyl acetate copolymer, the ethylene-acrylate copolymer;
Described wax is the mixture of one or more materials in paraffin, Microcrystalline Wax, the Fischer-Tropsch wax;
Described tackifying resin is the mixture of one or more materials in petroleum resin, terpine resin, the esterified rosin;
Described oxidation inhibitor is mixed by 50% antioxidant 1076 and 50% oxidation inhibitor 168;
Described surface slip agent is the mixture of one or more materials in erucicamide, amine hydroxybenzene, the calcium stearate.
Described hot melt adhesive coating film preparation of compositions method, step is as follows by weight:
(1) batch mixing: get main polymer 50-80 part, wax 15-30 part, tackifying resin 20-40 part, oxidation inhibitor 0.3-1 part, slipping agent 0.1-0.5 part, raw material is mixed, drop into the forcing machine hopper then;
(2) preheating: forcing machine start preheating, first section temperature set 120-140 ℃, and second section the-the 5th section temperature set and successively decreased 8-15 ℃ successively;
(3) discharging: after forcing machine is heated to design temperature, open the charging switch, start extruder screw, speed setting 200-400rpm; Temperature of cooling water is set 6-10 ℃, the extruding pelletization moulding, remove moisture after, packing namely gets product hot melt adhesive coating film composition.
Main polymer of the present invention adopts SEBS, SEPS, and the mixture of Low Density Polyethylene, ethylene-vinyl acetate copolymer and ethylene-acrylate copolymer, it will act on and provide film-forming properties, and intensity and toughness are provided.Add SEBS or SEPS, improve glued membrane toughness, increase tensile strength, improve the consistency of mould material and hot melt adhesive; Add Low Density Polyethylene, improve tensile strength, can reduce the thickness of coating film; Add ethylene-vinyl acetate copolymer and ethylene-acrylate copolymer, improve elasticity and the ductility of coating film, improve the consistency of coating film and hot melt adhesive.
Add tackifying resin, improve the consistency of coating film and hot melt adhesive, reduce coating film composition hot melt viscosity, be conducive to the die head film extrusion; Add Fischer-Tropsch wax, reduce the coating film melt viscosity, increase hot melt adhesive and the consistency of coating film when coextrusion, prevent from coating back blob of viscose adhesion.Fischer-Tropsch wax is synthetic wax, narrow molecular weight distribution, and curing speed is fast, and it is Overmolded to be conducive to the hot melt adhesive high speed.
For reducing product aging trend in production, film extrusion and the follow-up use, adopt compound antioxidant.The experimental verification of body series process, when the ratio of compound antioxidant is 1:1, thermostability the best.
For reducing the dynamic friction factor in coating film and the hot melt adhesive coextrusion process, improve the stability that coating film is extruded, prevent adhesion between blob of viscose, increase the smooth finish on coating film surface, adopt composite surface slip agent, the experimental verification of body series process, when the ratio of composite surface slip agent erucicamide and amine hydroxybenzene is 1:0.5, smooth property the best.
The present invention mixes raw material earlier in the process of making hot melt adhesive coating film composition according to formula rate, add hopper, treat that forcing machine is heated to design temperature after, open hopper, start extruder screw, heat mixing, cooling granulation.Purpose is: hot melt adhesive coating film composition melt viscosity is big, and mobile poor, the thermal oil reactor is produced incompatible, and it is relatively good to use forcing machine to produce; And the forcing machine design temperature is low, and the heating mixing time is short, can reduce the product thermal ageing.
Hot melt adhesive coating film composition of the present invention, the low and hot melt adhesive of raw materials cost has good consistency, and far to build the automatic packaging line matching good with method, and the coating film excellent heat stability is not easy charing, can effectively reduce machine cleaning frequency, enhances productivity.
The present invention has following advantage: this product processes is simple, and is good with the hot melt adhesive consistency; It is good that this product and method are far built the pack-thread matching, effectively improves Overmolded efficient; This product cost is lower than the film imported material more than 50%, for the client saves packing cost.
