Problems solved by technology

Developed countries such as Europe, America, Japan and the Middle East have applied a large number of CPVC materials to the chemical industry, which has achieved good results; my country is also a large chemical country. At present, metal, cement, enamel and conventional plastic rubber materials are mainly used in the industry, and CPVC materials are rarely used. This is mainly because CPVC materials are mainly imported, and the price is high, which limits wide-scale application. However, domestic manufacturers started late in the research and development of CPVC, and the quality of CPVC resin and formulation materials produced is poor. It is difficult to meet the requirements of industrial production, which limits this. Promote the use of materials

Abstract

The invention discloses a high-vicat anticorrosion high-strength CPVC (chlorinated polyvinyl chloride) plate, having vicat softening point of between 110-120 DEG C, tensile strength of 52-61 MPa and thermal deformation temperature of 108-116 DEG C; the plate is prepared from, by weight, 80-100 parts of CPVC resin, 5-20 parts of PVC resin, 4-6 parts of a thermal stabilizer, 0.5-2 parts of an auxiliary stabilizer, 1-2 parts of pentaerythritol stearate, 1-4 parts of an external lubricant, 1-4 parts of an internal lubricant, 0.5-3.5 parts of a processing aid, 2-5 parts of an impact modifier, 3-8 parts of filling material, and 0-0.08 part of a pigment. The CPVC material produced herein is 10-30% lower in cost than abroad like products; all the other aids are commercially available materials, having low price; by integrated calculation, the plate is 20-40% lower in cost than abroad formulations, and is approximately the same as the abroad formulations in performance; therefore, the plate has high market competitiveness.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a high-vicat, corrosion-resistant, high-strength CPVC plate and a preparation method thereof. Background technique [0002] Many acidic, alkaline, and high-salt liquids and solids are produced in the chemical production process. Many of these substances contain a lot of heat, so special devices are required for storage or transfer of these substances. At present, the storage devices in the chemical production process are mainly composed of stainless steel, glass fiber reinforced plastics, enamel, cement and other engineering plastics or rubber-lined materials. Stainless steel materials are not corrosion-resistant and have a short service life, and the rust produced will affect product quality; the comprehensive performance of glass fiber reinforced plastics Good, but it is brittle at low temperature, and it will produce a lot of pollution during construction, which wi...
