PVC building material and preparation method thereof

Abstract

The invention discloses a PVC building material and a preparation method thereof. The PVC building material is prepared from, by weight, 30-50 parts of PVC resin, 10-15 parts of acetyl trioctyl citrate, 5-10 parts of stearic acid, 8-15 parts of perlite powder, 12-15 parts of ethyl acetate, 12-18 parts of straw powder, 15-25 parts of kaolin, 4-9 parts of carbonyl iron powder, 10-20 parts of corundum powder, 11-17 parts of olive oil, 2-8 parts of titanium dioxide, 3-7 parts of foaming additive, 1-5 parts of antioxidant and 2-6 parts of toughening agent. According to the PVC building material, the PVC resin, the acetyl trioctyl citrate, the stearic acid, the perlite powder, the ethyl acetate, the straw powder, the kaolin, the carbonyl iron powder, the corundum powder, the olive oil and the titanium dioxide are effectively proportioned, and the PVC building material has good anticorrosive, heat-insulation, waterproof and fireproof performance and the like and can meet the green and environmentally friendly requirements of the green and environmentally friendly, and it can be also ensured that the material has the same stability as an original building material.

Description

technical field [0001] The invention relates to the technical field of building material production, in particular to a PVC building material and a preparation method thereof. Background technique [0002] As early as the 1940s, it was discovered that nitrile rubber and PVC were used together for research. Nitrile rubber has a certain polarity, and the solubility parameters of PVC are very close. They are both amorphous polymers. Good compatibility, so they are usually blended, and the alloy material obtained has excellent weather resistance, solvent resistance, good mechanical strength and processing performance, and is widely used in seals, wire and cable sheathing, Oil pipeline and other fields. The alloy materials of nitrile rubber and polyvinyl chloride are divided into cross-linked type and non-cross-linked type. The cross-linked alloy is insoluble and infusible, which is difficult to recycle and causes serious pollution to the environment. Although the non-cross-li...

Problems solved by technology

The alloy materials of nitrile rubber and polyvinyl chloride are divided into cross-linked type and non-cross-linked type. The cross-linked alloy is insoluble and infusible, which is difficult to recycle and causes serious pollution to the environment. Although the non-cross-linked alloy has processing performance Good, but the mechanical properties are not ideal

[0003] At present, PVC pipes are widely used in water supply, construction, drainage, sewage, chemical and other technical fields because of their strong corrosion resistance, high strength, and good rigidity. However, due to the poor wear resistance of PVC pipes and the inability to use them in harsh environments, the use of PVC pipes has been restricted to a large extent. In the prior art, there are PVC pipes with corrosion-resistant components, but the effect is relatively low. Poor, can't meet demand
