Abstract

The invention discloses an anti-aging PVC (Polyvinyl Chloride) board with excellent thermal stability and a preparation method of the anti-aging PVC board. The anti-aging PVC board comprises the following raw materials in parts by mass: chloroethylene, epoxy compounds, a rare earth catalyst, di-cetyl peroxydicarbonate, modified montmorillonite, nano calcium carbonate, 2-(2-hydroxy-4-hexoxyphenyl)-4,6-diphenyl-1,3,5-triazine, 2,2'-methylene-bis(4-tert-butyl-6-benzotriazolyl) phenol, pentaerythritol ester, a dispersing agent and a plasticizer. The PVC board prepared by the preparation method disclosed by the invention is excellent in thermal stability and is difficult to decompose and discolor under light and high temperature conditions, release of toxic gases is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of building boards, in particular to a PVC board with excellent thermal stability and anti-aging performance and a preparation method thereof. Background technique [0002] In recent years, due to the outstanding mechanical properties and corrosion resistance of PVC materials, the utilization rate in the field of building materials has increased year by year. However, PVC materials have poor thermal stability. If PVC products are placed in a high-temperature environment or exposed to sunlight for a long time, they will decompose and produce hydrogen chloride gas. The hydrogen chloride gas produced by the decomposition is not only harmful to human health, but also further catalyzes the decomposition of PVC products, making the products gradually turn yellow and brittle, resulting in a decrease in the physical properties of the products and affecting the service life. Contents of the invention [0003] Base...
