Abstract

The invention relates to a composite material, in particular to a novel PVC foamed profile and a preparation method thereof. The novel PVC foamed profile is prepared from components in parts by weight as follows: 100 parts of PVC, 3-25 parts of a toughening agent, 10-50 parts of calcium sulfate, 3-8 parts of a stabilizer, 0.6-3.5 parts of a foaming agent, 2-15 parts of a foaming control agent, 0.3-2.0 parts of an internal lubricant, 0.3-2.0 parts of an external lubricant, 1.0-1.5 parts of a PVC processing agent and 0.3-1.2 parts of a coupling agent. The content of filler in the PVC foaming system can be increased by 10%-30% in the formula while the weight of the product per meter is kept basically unchanged, the material has higher cost performance, the novel PVC foamed profile is developed according to the technical principle of a new material, is innovative in new material application, has the characteristics of facilitating resource utilization and being energy-saving, environment-friendly, green and economical and is suitable for industrial production.

Description

technical field [0001] The invention relates to composite materials, in particular to a new type PVC foam profile and its preparation method. Background technique [0002] PVC wood-plastic materials are environmentally friendly products, and the processing technology is very mature. Through molds and co-extrusion, products with novel shapes and appearances can be designed, and the appearance is very close to wood, and some are even more beautiful than wood. The material can be recycled and reused, which brings good economic and social effects in terms of promoting resource recycling, energy conservation and emission reduction, and sustainable economic development. However, existing PVC wood-plastic materials still have shortcomings such as excessive production cost pressure, poor material mechanical properties and weather resistance, poor corrosion resistance, and high production energy consumption, which limits its application field. my country is a country with a large d...
