Abstract

The invention discloses a nano-modified PVC composite foaming material. The raw materials include the following components in parts by weight: 80-100 parts of polyvinyl chloride resin; 10-25 parts of short glass fiber; 2-12 parts of composite nano-modifier ; 0.4-6 parts of foaming agent; 1-6 parts of lubricant; 1-5 parts of stabilizer; 0.5-1.2 parts of processing aid. The PVC composite foam material prepared by the invention has the characteristics of high strength, good toughness and excellent processing performance, which solves the technical problems of insufficient strength, insufficient toughness and poor processing performance of existing PVC materials, and can be widely used in high-speed rail and automobile interior decoration parts, daily necessities, home building materials, packaging, advertising decoration and other fields.

Description

technical field [0001] The invention relates to the technical field of polymer material modification, in particular to a nano-modified PVC composite foaming material and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) resin is a polar non-crystalline high polymer, its products have good physical and chemical properties, and can be widely used in the fields of industry, construction, agriculture and daily necessities. At present, furniture and building materials products with PVC resin as the main raw material have become the second pillar of my country's plastics industry, with an average annual growth rate of more than 15%. This is due to the advantages of low cost, excellent performance and recyclable recycling of PVC composite materials, which is in line with the general trend of environmental sustainable development and circular economy. [0003] Due to the superior performance of PVC materials and the protection of the environment, ...
