Environment-friendly white latex used in low-temperature environment and production process thereof

Abstract

The invention provides environment-friendly white latex used in a low-temperature environment and a production process thereof. The environment-friendly white latex used in the low-temperature environment is prepared from the following components: vinyl acetate-ethylene copolymer emulsion, vinyl versatate copolymer emulsion, self-crosslinking acrylic resin, a PH regulator, butyl acrylate, diacetone acrylamide, N-hydroxymethyl acrylamide, polyvinyl formal, deionized water and a defoaming agent. The environment-friendly white latex comprises the following components in parts by weight: 550-750 parts of vinyl acetate-ethylene copolymer emulsion; 150-250 parts of vinyl versatate copolymer emulsion; 150-250 parts of self-crosslinking acrylic resin; 5-15 parts of a pH regulator; 5-25 parts of butyl acrylate; 30-70 parts of diacetone acrylamide; 15-45 parts of N-hydroxymethyl acrylamide; 80-140 parts of polyvinyl formal; 90-260 parts of deionized water; and 3-6 parts of a defoaming agent. The environment-friendly white latex used in the low-temperature environment and the production process thereof have the advantages of better safety and strong environmental protection property.

Description

technical field [0001] The invention relates to the field of white latex, in particular to an environment-friendly white latex used in a low-temperature environment and a production process thereof. Background technique [0002] White latex is one of the water-soluble adhesives with the widest application, the largest amount, and the longest history. It is a thermoplastic adhesive prepared by polymerization of vinyl acetate monomer under the action of an initiator. It can be cured at room temperature, cured quickly, and has high bonding strength. The bonding layer has good toughness and durability and is not easy to age. [0003] The use of white latex is very common, but in some low-temperature and humid environments, white latex is prone to shedding, discoloration, etc., and some white latex contains benzene, toluene, ethylbenzene, xylene, phthalates, etc. Hazardous substances, with certain potential safety hazards, low environmental protection. [0004] Therefore, it is...
