Heat-resistant styrene resin-containing hot melt glue

Abstract

The invention discloses heat-resistant styrene resin-containing hot melt glue. The hot melt glue is prepared from the following raw materials in parts by weight: 65-70 parts of EVA, 10-20 parts of modified tackifying resin, 1-3 parts of cetyl trimethyl ammonium bromide, 5-10 parts of styrene resin, 10-15 parts of xylene formaldehyde resin, 1.3-1.5 parts of a crosslinking agent TAC, 15-20 parts of neoprene, 1-2 parts of paraffin oil, 0.5-0.8 part of sodium carboxymethylcellulose, 2-5 parts of epoxidized soybean oil, 25-30 parts of nano potassium feldspar powder, 1.3-1.9 parts of casein and 1.5-1.9 parts of citric acid. According to the heat-resistant styrene resin-containing hot melt glue, the heat resistance of the hot melt glue can be improved through the usage of nano potassium feldspar powder and casein; styrene resin and neoprene are subjected to intercalation modification, so that the mechanical property of the resin can be improved, the heat deflection temperature is increased, the water-absorbing property is low, and when the resin subjected to intercalation modification is used to prepare the hot melt glue, the compatibility among the raw materials of the hot melt glue is strengthened, and the viscosity, heat resistance and waterpfoofness of the hot melt glue are improved.

Description

technical field [0001] The invention belongs to the field of adhesives, in particular to a heat-resistant hot-melt adhesive containing styrene resin. 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...

AI Technical Summary

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.
