Opaque, high-impact MBS that is easy to process PVC and its manufacturing method

摘要

The present invention discloses an opaque high-impact MBS that is easy to process PVC and a method for manufacturing the same, and relates to the production and manufacturing technology area of a PVC auxiliary. In terms of mass fraction, 1% to 20% of deep structures; Core layer structure 70% to 85%; The shell layer structure is composed of 5% to 20%, the deep structure is a copolymer of semi-rigid light cross-linked styrenic monomer and acrylate-based monomer, and the core layer structure is composed of soft light cross-linked butadiene and styrene with a low vitrification temperature. It is a polymer, and the shell layer structure is a copolymer of styrene, butyl acrylate and methyl methacrylate having a high vitrification temperature. The present invention solves problems such as low anti-impact strength and poor processing fluidity existing in MBS products for non-transparent PVC products.
