Problems solved by technology

However, due to the large number of polar C-Cl bonds in the molecular chain structure of PVC resin, there is a large force between molecules, so compared with other general-purpose resins, PVC is a hard and brittle material with low impact strength and notch sensitivity. It is easy to crack when it is impacted by external force, so it is difficult to be used as a structural material
These shortcomings greatly limit the development of PVC in the field of high performance. In order to expand its application range, it is necessary to toughen and modify rigid PVC.
Commonly used elastomer tougheners can better improve its impact resistance, but at the same time it will significantly reduce the rigidity of the material itself.

Abstract

The invention discloses an anti-corrosion PVC board. The anti-corrosion PVC board is prepared from, by weight, 50-60 parts of PVC S-800, 20-30 parts of PVC S-1000, 20-30 parts of PVC recycled materials, 20-25 parts of ultra high molecule weight polyethylene, 0.4-0.7 part of a foaming agent, 1-1.5 parts of calcium-zinc stabilizer, 2-4 parts of a modifier NCR, 0.3-0.5 part of PE wax, 4-5 parts of a processing agent k10, 15-20 parts of magnesium hydroxide, 1-2 parts of antimonous oxide, 40-50 parts of modified nano-calcium carbonate and 2-4 parts of glass fibers. A conventional extruder is adopted to conduct extruding and shaping. The anti-corrosion PVC board has the advantages of being good in anti-corrosion performance, high in impact resistance and tensile strength, resistant to chemical corrosion and low in cost.

Description

technical field [0001] The invention relates to the field of PVC sheets, in particular to an anti-corrosion PVC sheet and a preparation method thereof. Background technique [0002] With the development of the national economy and urban construction, PVC has excellent performance and is widely used in industry, agriculture, daily life and public utilities. However, due to the large number of polar C-Cl bonds in the molecular chain structure of PVC resin, there is a large force between the molecules. Therefore, compared with other general-purpose resins, PVC is a hard and brittle material, with low impact strength and notch sensitivity. It is easy to be brittle and cracked when it is impacted by external force, and it is difficult to be used as a structural material. These shortcomings greatly limit the development of PVC in high-performance fields. In order to expand its application range, it is necessary to toughen and modify rigid PVC. Commonly used elastomer tougheners ...
