Processing performance additive and preparation method thereof

Abstract

The invention relates to the technical field of high polymer materials, in particular to a processing performance additive and a preparation method thereof. An acrylic ester processing agent ACR and an impact modifier MBS are added into a CPVC resin formula system, and the processing agent ACR and the impact modifier MBS can cause high torque of CPVC in the processing process and can also cause reduction of the vicat softening point of a CPVC fire-fighting pipe in the using process. Based on the problems, the invention provides a processing performance additive. The processing performance additive is obtained by copolymerizing vinyl chloride, vinylidene chloride and vinyl versatate as raw materials. The chain structures of vinyl chloride and vinylidene chloride in the molecular structure of the processing performance additive have good compatibility with CPVC, which is benficial to the improvement of the comprehensive performance of the CPVC fire-fighting pipe.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a processing modification aid and a preparation method thereof. Background technique [0002] In recent years, thanks to the vigorous development of real estate and the needs of the renovation of old communities, plastic pipes have achieved unprecedented development. Among them, CPVC fire-fighting pipes are favored by people because of their flame-retardant, heat-resistant, chemical-resistant, antibacterial, and long-life characteristics, and their usage is increasing. [0003] The application of CPVC fire-fighting pipes has high requirements for its processing performance, heat resistance, flame retardancy and impact resistance. In order to improve the processing performance of CPVC fire pipes, the common method is to add acrylic processing aid ACR and impact modifier MBS to the CPVC resin formulation system. It will lead to a higher torque of CPVC during processing,...
