Abstract

The invention discloses an odorless high temperature-resistant PVC (polyvinyl chloride) modified material with high transparency and a preparation method thereof. The odorless high temperature-resistant PVC modified material is prepared from the following raw materials in parts by weight: 60 to 80 parts of PVC, 5 to 10 parts of glass fiber, 1 to 2 parts of heat stabilizer, 6 to 12 parts of plasticizer, 5 to 10 parts of anorthite, 6 to 12 parts of mullite, 0.5 to 3.5 parts of antioxidant, 0.6 to 1 part of external lubricant, 0.3 to 0.7 part of internal lubricant, and 1 to 2 parts of other additives. The odorless high temperature-resistant PVC modified material has the advantages that the stability and heat-resistant property of the PVC material can be well improved, the service life of thePVC material is prolonged, and the prepared PVC material has good transparency.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a highly transparent, odorless, high-temperature-resistant PVC modified material and a preparation method thereof. Background technique [0002] PVC is a white powder with an amorphous structure, the degree of branching is small, the relative density is about 1.4, the glass transition temperature is 77-90°C, it begins to decompose at about 170°C, and it has poor stability to light and heat. When exposed to sunlight, it will decompose to produce hydrogen chloride, and further autocatalyze the decomposition, causing discoloration and rapid decline in physical and mechanical properties. In practical applications, stabilizers must be added to improve the stability to heat and light. [0003] The high temperature resistance and transparency of the PVC transparent material in the prior art are very poor, and the service life of the material is very short, which cannot meet th...
