Problems solved by technology

However, this method only focuses on the fluidity of polyvinyl chloride, which improves its processing performance, but the final product prepared according to its formula and preparation method still has the disadvantages of poor flame retardancy and instability
[0007] Therefore, it can be seen from the above prior art that in the process of polyvinyl chloride modification, improving its flame retardancy and improving its fluidity are mutually restraining solutions. If the flame retardancy is improved, the fluidity will decrease, and if the fluidity improved, the flame retardancy decreased

Abstract

The invention discloses a high-fluidity high-fire resistance polyvinyl chloride composite material and a method for preparing the same. The composite material mainly comprises the following components in part by weight: 100 parts of polyvinyl chloride, 3 to 6 parts of stabilizer, 40 to 50 parts of plasticizer, 6 to 10 parts of brominated flame retardant, 6 to 10 parts of zinc borate, 4 to 8 parts of antimony trioxide and 15 to 25 parts of flow modifier. The preparation method comprises the following steps of A: mixing raw materials in a ratio; and B: performing extrusion and granulation. The polyvinyl chloride composite material has quite high fluidity and fire resistance, has excellent heat resistance, weathering resistance and ultraviolet resistance, does not contain phthalic acid and heavy metal and is an environment-friendly polyvinyl chloride composite material.

Description

technical field [0001] The invention relates to a polyvinyl chloride composite material and a preparation method thereof, in particular to a soft polyvinyl chloride composite material with high fluidity and high flame retardancy and a preparation method thereof, belonging to the technical field of new materials. Background technique [0002] Polyvinyl chloride (PVC) is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. Due to the advantages of high chemical resistance, good electrical insulation performance, stable physical and chemical properties, and low price, polyvinyl chloride is widely used in various fields such as industry, agriculture, transportation, construction, communication, and medical care. However, pure polyvinyl chloride has certain defects in mechanical strength and flame retardancy, which limit its use. In order to improve the flame retardancy and mechanical properties of PVC, it is usually necessary to add other compon...
