Artwork with modified urea-formaldehyde resin as adhesive and preparing method thereof

Abstract

The invention discloses a binder and making method of modified urea-formaldehyde resin, which comprises the following steps: adopting urea-formaldehyde resin, fill, reinforcer, deoxidation agent, formaldehyde catching agent, anti-aging agent, anti-shrinking agent, hardener and auxiliary reinforcer; adopting modified copolymer of acrylic acid, sodium acrylate, N, N-dimethylamino propyl methyl acrylamide as anti-shrinking agent; making polyacrylamide solution reacted by acrylamide and ammonium persulphate as formaldehyde catching agent; allocating each component according to proportion; blending evenly; casting; extracting into vacuum; stripping; stewing; drying naturally; coating a layer of polymethacrylate paint on the surface of product; proceeding colorful paint; obtaining the product.

Description

technical field

[0001] The invention relates to a method for making a handicraft, in particular to a handicraft using urea-formaldehyde resin with low formaldehyde content as an adhesive and a method for making the handicraft. Background technique

[0002] The raw materials used in the production of resin handicrafts are mainly stone, bamboo, wood, gypsum, resin, etc. Most of the resins used in resin handicrafts are unsaturated polyester or a small part of epoxy resin, etc., and urea-formaldehyde resin is rarely used . Wang Meigui (Wang Meigui. Journal of Tianjin Institute of Light Industry, 1998, 1) introduced the curing principle and production process of imitation crystal handicrafts made of unsaturated polyester, the raw materials used in the production process, production steps, formula control and attention The problem. Pan Yanfeng (Pan Yanfeng. SME Technology, 2000, 2) introduced the use of unsaturated polyester to imitate cloisonne crafts, which is essentially diff...
