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.

Description

technical field [0001] The invention relates to the technical field of PVC pipe 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...
