Abstract

The invention provides formaldehyde-free glue synthesized from chemical materials for automotive trims and a preparation method of the formaldehyde-free glue. The formaldehyde-free glue is prepared from polyvinyl acetate, ethylene glycol monoethyl ether, dibutyl acetate, a water retention agent, a food defoamer, a flame retardant, a food preservative, a thickener and water in a certain proportion. The preparation method comprises the steps of controlling the temperature of a solution reaction system at 30-40 DEG C, and uniformly stirring by virtue of a stirring machine. According to the formaldehyde-free glue, the problem that common glue contains toxic substances such as formaldehyde is solved; and the formaldehyde-free glue has the excellent characteristics of environment friendliness, safety in operation, relatively high curing speed, low processing cost and the like.

Description

technical field [0001] The invention relates to the technical field of chemical industry, and more specifically relates to a kind of chemical material to synthesize a kind of formaldehyde-free glue for automobile interior decoration. Simultaneously, the invention also relates to a preparation method of the formaldehyde-free glue for automobile interior decoration. Background technique [0002] In our country, with the continuous high-speed development of the economy and the acceleration of the pace of cars entering the family, the environmental pollution inside the car has attracted more and more attention. Most of the car interior decoration uses a variety of non-metallic materials such as artificial leather, polyurethane foam, plastic wallpaper, latex sponge, artificial carpet, cloth, velvet and wood. The interior parts are bonded to the interior of the car by glue, such as the ceiling, carpet, door panels, instrument panel, etc., to increase the beauty of the car interio...
