Problems solved by technology

Polyvinyl chloride itself is self-extinguishing, but a large amount of plasticizer is often added during processing and use, which greatly improves the flammability of PVC products, and produces a large amount of smoke when the products are burned, making it difficult for people to identify directions and paths Difficulties in rescuing and escaping from fire

Abstract

A purpose of the present invention is to provide a transparent polyvinyl chloride flame retardant material capable of improving the shortage of polyvinyl chloride materials, and a preparation method thereof. Polyvinyl chloride (PVC) resin has excellent comprehensive performances of corrosion resistance, electrical insulation, flame resistance, high mechanical strength and the like, and is widely used in national economy fields of agriculture, industry, daily life and the like. Polyvinyl chloride has self-extinguishing property, but a large amount of the plasticizer is added during the processing and the use so as to substantially improve the flammability of the pvc product, and when the product can produce a lot of smoke when burning, such that people difficultly identify the direction and the path so as to make the rescue and the escaping from the fire scene difficult. The transparent polyvinyl chloride flame retardant material of the present invention can overcome the disadvantages of the original polyvinyl chloride material, and provides the great significance for the application and the further popularization of the polyvinyl chloride material.

Description

technical field [0001] The invention belongs to the technical field of polyvinyl chloride material production and aims to improve the original deficiencies of polyvinyl chloride. Produce products that meet social needs. Background technique [0002] Polyvinyl chloride, English name: polyvinylchloride, abbreviated name PVC. Its structural formula is: -[CH2-CHCl]-n. [0003] Polyvinyl chloride (PVC) resin has excellent comprehensive properties such as corrosion resistance, electrical insulation, flame retardancy and high mechanical strength, and is widely used in various fields of the national economy such as industry, agriculture and daily life, especially in recent years. The huge demand for polyvinyl chloride products has made vinyl chloride products a very competitive plastic variety, and its output ranks second only to polyethylene. Polyvinyl chloride itself is self-extinguishing, but a large amount of plasticizer is often added during processing and use, which greatly...
