Abstract

The invention discloses a flame-retardant urea-formaldehyde resin adhesive which contains the following raw materials in parts by weight: 40-60 parts of formaldehyde, 120-140 parts of urea, 2-3 parts of polyvinyl alcohol, 5-7 parts of melamine, 0.2-0.4 parts of sodium myrastate, 2-4 parts of decabromodiphenyl ethane, 1-2 parts of ammonium dihydrogen phosphate, 0.6-1 part of tricresyl phosphate, 2-3 parts of tackifying aid, 0.1-0.3 parts of calcium acetylacetonate, 0.3-0.5 parts of 3,2-thiolbenzimidazole, 0.4-1 part of sodium dimercaptosulphonate and 0.1-0.3 parts of silane coupling agent KH560. According to the invention, formaldehyde, urea, melamine and aids are blended and modified, the finished product has good crosslinking property, stable structure, perfect water resistance, anti-aging property, flame retardance and the like and long service life; and the added tackifying aid can be effectively combined into a copolymer adhesive molecular network, so that the tackiness and the biodegradability and disintegration of subsequent products are enhanced, and the comprehensive performance is excellent.

Description

technical field [0001] The invention mainly relates to the field of resin glue, in particular to a flame-retardant urea-formaldehyde resin glue. Background technique [0002] Urea-formaldehyde resin is a polymer obtained by the reaction of urea and formaldehyde. Also known as urea-formaldehyde resin. English abbreviation UF. Cross-linking occurs during processing and molding, and the product is an insoluble and infusible thermosetting resin. The color of cured urea-formaldehyde resin is lighter than that of phenolic resin, and it is translucent. It is resistant to weak acids and alkalis, has good insulation performance, excellent wear resistance, and is cheap. It is necessary to continuously improve the performance of urea-formaldehyde resin glue to improve its resistance, bonding performance, etc., so that it can be applied to more fields. Contents of the invention [0003] The object of the present invention is to provide a flame-retardant urea-formaldehyde r...
