Abstract
The invention discloses a non-formaldehyde adhesive used for an automobile trim. The non-formaldehyde adhesive is prepared from, by weight, 15-25 parts of starch, 1-1.78 parts of resin, 1-2.5 parts ofborax, 18-23 parts of a dispersing agent, 20-30 parts of polyvinyl acetate, 10-15 parts of 2-ethoxyethyl acetate, 0.1-0.2 part of a defoaming agent, 50-60 parts of liquid water, 1.6-3.2 parts of sodium hydroxide and 0.3-0.5 part of oxidation water. The oxidation time length of the oxidation water in summer is 1.5-3 hours and is 4-6 hours in winter, and the PH value of the adhesive is 7.1-7.9. Theprepared non-formaldehyde adhesive used for the automobile trim is healthy, environmentally friendly and free of pollution, peculiar smells in an automobile are reduced, potential hazards of health of a human body are prevented, meanwhile, the content of harmful substances is small, quality is stable, and application prospects are better.
Description
technical field [0001] The invention relates to the field of formaldehyde-free glue, in particular to a formaldehyde-free glue for automobile interior decoration. Background technique [0002] Formaldehyde-free glue is an adhesive that does not contain formaldehyde. It is mainly used in wood-based panels and building materials industries. In recent years, the hazards of formaldehyde have been paid more and more attention. Harmful, wood products made of formaldehyde-containing adhesives are used indoors, and the release period of formaldehyde can be as long as 15 years. Studies have shown that long-term exposure to low-dose formaldehyde can cause chronic respiratory diseases, nasopharyngeal cancer, colon cancer, brain tumors, menstrual disorders, Gene mutations in the nucleus, DNA single-strand cross-linking and DNA-protein cross-linking and inhibition of DNA damage repair, pregnancy syndrome, causing chromosomal abnormalities in newborns, leukemia, and memory and mental declin...
