Hard PVC plate

Abstract

The invention relates to a hard PVC plate which comprises the following components in parts by weight: 100 parts of PVC, 8 parts of a stabilizer, 5 parts of silica flour, 12 parts of bamboo fiber, 12 parts of glass fiber, 10 parts of nano calcium carbonate, 6 parts of light activated calcium carbonate, 5 parts of calcium chloride, 2 parts of titanium dioxide, 2 parts of glycoprotein and 2 parts of a processing agent. According to the invention, the PVC plate is high in hardness, high in transparency and good in wind pressure resistant performance, and can be used for the field of doors and windows of buildings.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a rigid PVC board. Background technique [0002] Plastic profiles are a wide range of materials, but due to the relatively small elastic modulus of PVC plastic profiles, there are currently insufficient bending stiffness in some applications, such as in the field of building doors and windows, and its wind pressure resistance is difficult to achieve. Require. Contents of the invention [0003] The object of the present invention is to provide a kind of rigid PVC plate aiming at the deficiencies of the prior art. [0004] The technical scheme adopted in the present invention is as follows: a rigid PVC board, the formula is composed of the following raw materials in parts by weight: 100 parts of PVC, 8 parts of stabilizer, 5 parts of quartz powder, 12 parts of bamboo fiber, 12 parts of glass fiber, nano calcium carbonate 10 parts, 6 parts of light activated calcium carbonate, ...
