Introduction of water-based acrylic structural pressure-sensitive adhesive This paper provides the introduction of a water-based acrylic structural adhesive, which is composed of a mixture of pretreatment liquid and seed liquid. The pretreatment liquid is emulsified by methyl acrylate monomer and modified monomer in a mixture of ice water and then emulsified again by adding […]
Adhesives are more common in our life, and can not be ignored in life. What kinds of adhesives are there? Let’s take a look. Polyacrylic resin: Mainly used in the production of pressure-sensitive adhesives, but also used in textile and construction fields. In recent years, domestic enterprises from abroad introduced several pressure-sensitive adhesive product production […]
The weakness of ordinary water-based acrylate PSA is poor bonding strength and heat resistance, and it is difficult to firmly bond on low surface energy materials. The molecular structure of organosilicon contains Si-O-Si bond and side chain organic groups, and its molecular chain is highly curly, the intermolecular association is small and the intermolecular attraction […]
The adhesion of PSA is mainly due to the van der Waals force and hydrogen bond formed between PSA and the surface of the bonded substrate. The surface of the bonded substrate has a complete structure and partial electron rearrangement. Aqueous acrylate emulsion has good surface wettability, so the adhesion and initial adhesion of corresponding […]
Acrylate PSA mainly includes a solvent, water-based acrylate PSA two categories: solvent acrylate PSA VOC(volatile organic matter) content is larger, and its in the environment, resources, and safety. There are many drawbacks, so the scope of its use is limited. The water-based acrylate PSA uses water as a solvent, which has the characteristics of environmental […]
