Abstract

The invention relates to the technical field of hot melt adhesives, in particular to an EVA edge-sealing hot melt adhesive with no adhesive line and low adhesive coating amount and a preparation method of the EVA edge-sealing hot melt adhesive. The EVA edge-sealing hot melt adhesive is prepared from, by weight, at least 25-45 parts of ethylene-vinyl acetate copolymer, 15-30 parts of petroleum resin, 2-10 parts of tackifying resin, 5-10 parts of viscosity modifier, 20-55 parts of filler and 0.01-0.05 part of antioxidant. The hot melt adhesive provided by the invention has the advantages of goodstrength, thin adhesive layer, adhesive saving, good flexibility of the adhesive layer, environmental protection, no harmful substances such as formaldehyde and toluene, no phthalate, no heavy metalsand the like, and compared with the color of a plate and a furniture edge banding, the adhesive line cannot be seen, and the effect of no stranded line is achieved.

Description

technical field [0001] The invention relates to the technical field of hot-melt adhesives, in particular to an EVA edge-sealing hot-melt adhesive with no glue line and low glue coating amount and a preparation method thereof. Background technique [0002] With the promotion and implementation of national industrial manufacturing 4.0, China's domestic intelligent manufacturing is developing rapidly. Traditionally, the furniture industry is a labor-intensive industry with a large number of workers, a lot of manual work, and a low degree of automation. Some large domestic furniture factories and wooden door factories Responding to the government's call and keeping up with the development of the world's manufacturing industry, a new factory has been established in accordance with the standards of Industry 4.0, which has greatly improved the production efficiency of the furniture industry and reduced labor costs, thereby reducing the entire furniture manufacturing cost. [0003] ...
