Abstract
The invention discloses a method for producing a general-purpose hot melt adhesive. A product to be produced is an ethylene-vinylacetate copolymer hot melt agent, a working principle of which is different from that of other types of adhesives; the hot melt adhesive is not cross-linked when bonded, is solidified without dependence on volatilization of a glue solvent, and restores to a solid-state naturally from a heating molten state via a cooling process. Thus, the bonding effect of the hot melt adhesive is realized based on the good wetting property of the hot melt adhesive to a bonding surface in the molten state, and the bonding strength generated in a cooling solidified state. The hot melt adhesive is mainly applied to corrosion-resistant coating for wireless binding of books, packages, furniture side sealing, assembly of automobiles and household appliances, shoemaking, carpet coatings and metal products. The hot melt adhesive comprises the following main components: 40 percent of ethylene-vinylacetate copolymer resin, terpene resin, paraffin wax, calcium carbonate, barium sulfate, titanium dioxide and barium stearate.
Description
Affiliated technical field:
Product of the present invention belongs to chemical field.
Background technology:
Product of the present invention is a kind of hot melt adhesive, is called for short the hot melt agent, because of it has very fast curing speed, for various materials, is difficult to cementitious non-polar plastic comprising some with other tackiness agent, all has good wetting property and higher Joint strength.Its raw material sources is abundant, and is cheap, therefore become one of the most rising tackiness agent.According to the chemical constitution of matrix, it is multiple that the hot melt agent can be divided into ethene-vinyl acetate copolymerization build, polymeric amide type, polyester type and polyurethane-type etc., wherein ethene-vinyl acetate copolymerization build most importantly.The curing of hot melt agent is different with the tackiness agent of other type, and it does not produce crosslinking reaction, does not also rely on the volatilization of glue solvent to reach the solidified purpose, and only is to return to solid-state from the heating and melting state naturally by process of cooling.Therefore, the bonding effect of PUR be rely on it when molten condition to glueing joint the good wellability in surface, and the glue-joint strength under the cooling curing state that produces is thus realized.The starting material that hot melt adhesive is used generally are not newly developed, yet the resin of proper formulation cooperates with the process resin equipment used, then the success with hot melt adhesive technology is relative, so, the production of hot melt adhesive is except using thermoplastic polymer, also to add some other composition, in order to manufacturability, cementability and the usability that improves hot melt adhesive.For example add stablizer and be used for anti-oxidation; Tackifier improve bonding strength; Paraffin reduces the viscosity-modifying surface properties; Various fillers can improve viscosity, fusing point and bonding strength.One of most important characteristic of hot melt adhesive is exactly a use temperature, if the hot melt adhesive temperature of fusion is low, then use temperature must be low, and this is a shortcoming.Creep can take place in low-melting hot melt adhesive at any time when load is arranged, having load the time can not keep dimensional stability, so hot melt adhesive is mainly as the location of not bearing load, so that the main drawback of hot melt adhesive is an intensity is low, poor heat resistance will be noted during use.At present, universal hot melt adhesive is mainly used in the corrosion resistant coating on assembling, shoemaking, carpet coating and the metal products of unsewn binding, packing, edge sealing of furniture, automobile and the household electrical appliance of books.This short adhesive solidification time, need not drying, do not contain solvent, pollution-free, solidify rapid, bonding widely, easy to use, be applicable to serialization production, be easy to store and transportation.Thereby invented this product.
Summary of the invention:
The present invention relates to a kind of production method of universal hot melt adhesive, concrete prescription is: (determine the weight of every kind of material according to the size of reaction vessel, this prescription only provides ratio) content is 65 parts of 40% ethene-vinyl acetate interpolymer resins, 15 parts (terpine resin is tackifier to terpine resin, it mainly acts on is Joint strength and the snappiness that increases matrix, improve the wetting property of glue and composition surface, terpine resin and ethene-vinyl acetate interpolymer matrix have good intermiscibility), 5 parts in paraffin, 4 parts in lime carbonate, 4 parts in barium sulfate, 2 parts of (lime carbonate of titanium dioxide, barium sulfate, titanium dioxide is filler), 5 parts of barium stearates (stablizer);
Embodiment:
The production of product of the present invention need divide for four steps, the first step: in reaction vessel, adding content earlier is 65 parts of 40% ethene-vinyl acetate interpolymer resins, simultaneously temperature is elevated to 80 ℃, make ethene-vinyl acetate interpolymer resin reach molten state, start stirrer, rotating speed is 30 rev/mins.Second step: add 15 parts of terpene resins, insulation continued stir about 20 minutes.The 3rd step: add 5 parts in paraffin, 4 parts in lime carbonate, 4 parts in barium sulfate, 2 parts of titanium dioxide, insulated and stirred reaction 30 minutes.The 4th step: add 5 parts of barium stearates, continue stirring and stop after 15 minutes stirring, obtain finished product after the cooling.
