Study on Preparation and Properties of Pressure Sensitive Adhesive of Acrylate Prepared by Miniemulsion

Abstract

Miniemulsion was prepared by means of different ratio of butyl acrylate with vinyl acetate emulsion pressure sensitive adhesive excellent performance. Focused on acrylic acid and vinyl acetate copolymers of different proportions of the glass transition temperature, molecular weight and molecular weight distribution of micro-factors, and build the macroscopic properties of the copolymer glass transition temperature and molecular weight between contacts. The use of APS as initiator under the conditions of the experiment found that with the increase of acrylic, PVC-floor, 180 peel strength composite materials decreased. While the molecular weight of butyl acrylate with the increase of the amount did not change significantly, the initial viscosity of the polymer and 180 º peel strength is improved, but the adhesive holding down quickly.
