Abstract

The invention discloses a heat-melting adhesive for an air-conditioning indoor unit and relates to the technical field of adhesives. The heat-melting adhesive for the air-conditioning indoor unit is prepared from the following ingredients in parts by mass: 30-50 parts of an ethylene-vinyl acetate copolymer (EVA), 30-60 parts of tackifying resin, 15-25 parts of a viscosity regulator and 0.5-1.0 part of an antioxidant. The heat-melting adhesive for the air-conditioning indoor unit solves such problems of heat-melting adhesives sold on market as odor, deep color, and poor ABS low-temperature adhesion effects.

Description

Technical field: [0001] The patent of the present invention relates to the field of adhesives, in particular to a hot-melt adhesive for an air-conditioner internal unit. Background technique: [0002] Water-based adhesives are used to fix EPS in traditional air-conditioning internal units, the curing speed is slow, and there is a certain amount of VOC volatilization, which leads to low production efficiency and is not environmentally friendly. Afterwards, major air-conditioning manufacturers gradually chose fast-curing, environmentally friendly hot-melt adhesives to replace them. However, in the selection process of hot-melt adhesives, due to the lack of general industry standards, there are generally problems in the application of hot-melt adhesives such as strong odor and poor low-temperature bonding effect on the internal machine material ABS, and there are quality risks. [0003] With the continuous growth of market demand for air conditioners and consumers' increasing ...
