Problems solved by technology

[0005] In order to prepare PVC with lower hardness, the traditional method is to add a large amount of low-molecular-weight plasticizers to reduce its hardness and increase its flexibility. However, this method will reduce the mechanical properties and heat resistance of the material, resulting in a decrease in elasticity and easy plasticity. Deformation, and as time goes by, low molecular plasticizers will migrate, which will make the softness, aging resistance and durability of the product worse

Description

technical field [0001] The invention belongs to the technical field of new materials and relates to a 90°C soft polyvinyl chloride elastomer sheathing material. Background technique [0002] With the emergence and development of polymer materials, fire accidents are also increasing. The flame retardant technology of polymer materials has emerged at the historic moment. The insulation and sheath of wires and cables are mostly made of polymer flame retardant materials. Serialization, diversification and performance evaluation The introduction of flame retardant test standards has promoted the development of flame retardant cable technology. [0003] Due to the lessons of cable fires, flame retardant cable technology has made great progress in recent years, and flame retardant cables have become an inevitable trend in cable development, thus actively promoting the flame retardant of PVC materials and the development of new products. [0004] Polyvinyl chloride (PVC) resin is a...
