PVC polyvinyl chloride (PVC) glue is part of the earliest plastics to be industrialized
22 Feb 2020
Compared with other synthetic varieties, PVC has the characteristics of fire resistance, chemical resistance, excellent electrical insulation and higher strength.
And the use of plasticizing and copolymerization, can make PVC properties have a significant change.
And about 30% plasticizer can be used as flexible flexible soft PVC;
No or little plasticizer or PVC copolymer system into hard PVC.
It is different from other plastics, from soft to hard, can be made into a variety of pipe, plate, profile, film, fiber, coating, artificial leather, wire and cable insulation products, in industry, agriculture and daily life to obtain a very wide range of applications.
In the synthetic adhesive, acrylate adhesive is more concern, when used in PVC glue material bonding, acrylate adhesive organic volatile content is low, and bonding firm, but when used in PVC film bonding, because the surface of PVC film is smooth, so the initial adhesion is low, bonding strength is poor.
Ma liqun et al. synthesized the copolymerized acrylate adhesive by using self-made s-01 emulsifier.
PVC film for wood, leather and other porous materials bonding, the effect is more significant.
S-01 emulsifier is accompanied by sodium dodecyl sulfate for better effect.
When the ratio of butyl acrylate to vinyl acetate is 33:4, the peel strength of the adhesive can reach 4300g/25cm, and the dosage of emulsifier is 4% of the monomer, the effect is better.
