Study on Low Temperature Stripping Material Based on the Modified Acrylate Polymer

Abstract

With the method of solution polymerization, we prepared a high conversion rate and larger molecular weight acrylate copolymer. Using synthetic copolymer, low temperature stripping material was compounded with the proportional certain kinds of crosslinking agent, plasticizer, thickener and release agent, according to the certain reaction temperature and the loading sequence. The material mechanical properties, stripping, decontamination rate was tested and characterization. We got the strip materials meeting the low temperature environment. Finally, the influence factors of copolymerization reaction: the choice of solvent, dosage of initiator, monomer and the dosage was discussed. To achieve higher conversion rate and larger molecular weight acrylate copolymer, the method of solution polymerization was adopted in this study. Low temperature stripping material was compounded with synthetic copolymer, together with crosslinking agent, plasticizer, thickener and release agent in certain proportion, according to reaction temperature and the loading sequence. This material’s mechanical properties, stripping, decontamination rate were tested and characterizing definition was done. Results showed this strip material could meet the requirement of low temperature environment. Finally, the influence factors of copolymerization reaction were discussed, including the choice of solvent, dosage of initiator, monomer and the dosage.
