Abstract

The invention relates to environment-friendly colorized flash hot-melt adhesive, which comprises main body resin, tackifying resin, a diluent agent, flash powder, pigment and solvent, wherein the main body resin is selected from one sort or a plurality of sorts of ethylene-vinyl acetate copolymer EVA, ethylene-butyl acrylate copolymer EMA, ethylene-acrylic acid copolymer EAA, ethylene-ethyl acrylic acid copolymer EEA, styrene-isoprene copolymer SIS, styrene-butadiene copolymer SBS and amorphous alpha-olefin polymer APAO; and the tackifying resin is selected from one sort or a plurality of sorts of rosin, polymerized rosin, 145 resin, 138 resin, terpene resin, petroleum resin or hydrogenant petroleum resin. The environment-friendly colorized flash hot-melt adhesive adopts the nontoxic flash powder which has excellent suspension property and is cheap, environment-friendly, unprecipitated and easy to be dispersed evenly as filler; moreover, the usage amount of the tackifying resin is increased, thereby substantially reducing product cost and improving product bonding strength and performance.

Description

technical field [0001] The invention relates to an adhesive in the chemical industry, in particular to an environment-friendly colored flashing hot melt adhesive. Background technique [0002] Ethylene-vinyl acetate copolymer (EVA) based hot melt adhesives can be widely used in various industries. As production automation increases, so does the demand for this product. At present, there are many kinds of hot melt adhesives sold in the market, but the color is single, usually yellow or five colors; ethylene-vinyl acetate copolymer (EVA) is mostly used as the main raw material, and the cost is relatively high. With the rapid development of human social civilization, the market requires hot melt adhesives to be in harmony with the color of the adherend, which does not weaken the bonding strength, but also requires beautiful, durable, bright, bright and cost-effective, especially in the handicraft and toy industries. protrude. Contents of the invention [0003] The technica...
