Abstract

The invention provides non-formaldehyde glue for synthesizing automotive interiors by utilizing chemical materials. The non-formaldehyde glue is prepared from polyvinyl acetate, ethoxyethanol acetate, sec-butyl acetate, a water-retaining agent, an edible defoaming agent, a flame retardant, an edible preservative, a thickening agent and water according to a certain proportion. A preparation method for the non-formaldehyde glue comprises the steps of controlling the temperature of a solution reaction system to 30-40 DEG C, and stirring uniformly by using a stirring machine. The non-formaldehyde glue provided by the invention solves the problem of toxic substances such as formaldehyde contained in common glue and has the excellent characteristics of environment friendliness, safety in operation, higher 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. 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 interior. At present, most domestic automotive interior parts still use flammable, toxic, and environmentally polluting solvent-based adhesi...
