Problems solved by technology

[0002] Traditional PVC materials have the following disadvantages: poor weather resistance, easy to deform; poor antibacterial property, easy to breed harmful bacteria; not environmentally friendly, use lead salt stabilizer, harmful to human body; non-standard production process, the product is easy to yellow; insufficient modulus and strength , the product use safety level is generally low; the processing level is low, and the added value of the product is low
However, due to the different shrinkage of the two parts of the material, a large internal stress may appear in the alternating hot and cold environment, resulting in cracking of the material, and it does not involve environmental protection performance and antibacterial performance.

Abstract

The invention discloses a green antibacterial carbon fiber reinforced PVC (polyvinyl chloride) material and a preparation method thereof. The green antibacterial carbon fiber reinforced PVC material is prepared from the following raw materials in parts by weight: 98-100 parts of PVC resin, 3-6 parts of titanium dioxide, 5-10 parts of modified kaolin, 5-12 parts of ACR impact resistance modifier, 3-5 parts of environment-friendly stabilizer, 0.5-3 parts of lubricant, 4-8 parts of inorganic antibacterial agent, 0.3-0.5 part of ultraviolet absorbent UV-327, 5-10 parts of modified barium sulfate, 2-5 parts of compound additive, 1-20 parts of short-cut carbon fiber coated with modified resin, and 0-5 parts of fluorescent whitening agent CBS. The green antibacterial carbon fiber reinforced PVC material of the invention has the advantages of excellent anti-fatigue performance, high and low temperature resistances, and waterproofness, small expansion coefficient, light weight, as well as excellent antibacterial performance and environment friendliness.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a green antibacterial carbon fiber reinforced PVC material and a preparation method thereof. Background technique [0002] Traditional PVC materials have the following disadvantages: poor weather resistance, easy to deform; poor antibacterial property, easy to breed harmful bacteria; not environmentally friendly, use lead salt stabilizer, harmful to human body; non-standard production process, the product is easy to yellow; insufficient modulus and strength , the product use safety level is generally low; the processing level is low, and the added value of the product is low. Therefore, it is of great significance to prepare reinforced materials with green and antibacterial effects. [0003] Chinese Patent Application No. 201210043789.X discloses a glass fiber reinforced PVC material and its preparation method, in which the dry blend added with chopped glass fiber str...
