Problems solved by technology

Since EVA resin is a thermoplastic resin, it has limited high and low temperature resistance and low softening point, and most of the main auxiliary tackifiers are polymers with small molecular weights, which only reduce the melt viscosity and improve the wettability and initial strength. The role of stickiness, itself is not resistant to high and low temperature, resulting in the shortcomings of EVA hot melt adhesive not resistant to high and low temperature; at the same time, EVA hot melt adhesive also has low bonding performance, not resistant to fat oil, easy to produce skinning and not suitable for large Disadvantages such as area coating and adhesion
[0003] At present, with the rapid development of the PET industry, the amount of discarded PET has also increased, which has brought serious pollution to the environment.

Abstract

The invention discloses a waterproof hot melt adhesive containing butyl rubber. The waterproof hot melt adhesive is prepared from the following raw materials in parts by weight: 45-50 parts of EVA, 30-40 parts of modified tackifying resin, 2-3 parts of cumene hydrogen peroxide, 1-3 parts of di-aminodecane, 0.5-0.9 part of citric acid, 0.5-1 part of stearic acid, 1-2 parts of sodium dodecyl benzene sulfonate, 1-3 parts of dioctyl terephthalate, 12-15 parts of butyl rubber, 1-2 parts of dodecyl trimethyl ammonium chloride, 10-20 parts of attapulgite, 40-55 parts of kaolinite and 1-3 parts of epoxy linseed oil. The raw materials of the EVA hot melt adhesive containing butyl rubber are excellent in dispersibility, and the high water tightness and the mechanical property are maintained.

Description

technical field [0001] The invention belongs to the field of adhesives, in particular to a waterproof hot-melt adhesive containing butyl rubber. Background technique [0002] EVA hot melt adhesive is formulated from EVA resin, tackifier, plasticizer, antioxidant, filler, etc. In today's society, EVA hot melt adhesives are widely used and used in the largest amount. It has excellent bonding performance, almost has thermal adhesion to various materials; excellent electrical properties; and its low melt viscosity, convenient sizing; good compatibility with other compounding agents, etc. EVA hot melt adhesives have been widely used in many fields such as book binding, food packaging, plastic bonding, ceramic repairing, mounting, clothing, shoes and hats molding, automobiles and building materials. Since EVA resin is a thermoplastic resin, it has limited high and low temperature resistance and low softening point, and most of the main auxiliary tackifiers are polymers with smal...
