Problems solved by technology

First of all, none of the three patents involves the improvement of the smoke suppression performance of the system, and we know that the smoke suppression performance is very important for household products and directly related to people's life and health; secondly, the above materials still have insufficient thermal stability , The defects of poor processing performance cannot meet the needs of high-temperature processing and molding, and also limit its application in some thin-walled, complex-shaped household products and injection molding products such as precision electronic devices; in addition, due to the butadiene bis The existence of bonds, the weather resistance of the product is poor, and the trial product is easy to turn yellow during use, which is also a defect that PVC / ABS alloy materials are difficult to overcome

Abstract

A process for preparing the smoke-inhibiting refractory polyvinyl chloride composition features that the multiple elements componding technique is used to improve the high-temp resistance to toughness of PVC, and the two kinds of high-toughness and -rigidity materials are used as its modifier. Its product has excellent high-temp resistance, flame-retarding nature, smoke inhibition and weatherability.

Description

technical field [0001] The invention relates to a polyvinyl chloride composition and a preparation method thereof, in particular to a heat-resistant and smoke-suppressing polyvinyl chloride composition and a preparation method thereof. Background technique [0002] Because home appliances require heat resistance, high rigidity, good dimensional stability, and creep resistance, engineering plastics such as acrylonitrile-butadiene-styrene copolymer (ABS) with good comprehensive performance and high surface gloss are mainly used at present. . However, because ABS resin has poor flame retardancy, poor weather resistance and high cost, it is necessary to develop new materials to improve its flame retardancy and weather resistance and reduce costs. [0003] Polyvinyl chloride (PVC) is a general-purpose plastic with high output and wide application. Because of its advantages of strong flame retardancy, good dimensional stability, excellent chemical resistance and low price, it als...
