Problems solved by technology

However, due to the high viscosity and poor fluidity of the traditional CPVC melt, the processing difficulty is too high, that is, the forming difficulty is high, so that when CPVC is made into corrugated boards, there will be obvious quality defects on the raised corrugations: thickness Uneven, uneven stress distribution, brittle, etc.

Abstract

The invention discloses a high-temperature-resistant weatherproof fireproof chlorinated polyvinyl chloride (CPVC) corrugated board with low heat conductivity, and a preparation method of the chlorinated polyvinyl chloride (CPVC) corrugated board. The corrugated board is prepared from the following raw materials by weight: 10-60 parts of CPVC resin, 30-70 parts of PVC (polyvinyl chloride) resin, 1-8 parts of composite lead salt stabilizer, 1-4 parts of processing aids, 8-12 parts of anti-impact aids, 25-75 parts of filler, 1.5-4.5 parts of lubricant, and a reasonable amount of colorant. The corrugated board has the advantages of high mechanical strength, excellent weatherability, high aging resistance and chemical stability and the like, and the formed raised corrugated board has higher thickness uniformity and uniform stress distribution, thereby being not easy to break due to stress concentration.

Description

technical field [0001] The invention relates to a corrugated board, in particular to a chlorinated polyvinyl chloride corrugated board with high temperature resistance, weather resistance, fire prevention and low thermal conductivity and a preparation method thereof. Background technique [0002] At present, most of the materials of color steel corrugated boards are steel, which will corrode and rust after a period of use, and color steel tiles are easily corroded by acidic substances. In hot weather, when the sun is exposed to the sun, the heat conduction and heat absorption are fast, so the heat insulation effect is poor; the noise is also louder when it rains. [0003] Due to the high hardness and mechanical properties of PVC boards, there are also many PVC corrugated boards. However, the hardness and mechanical properties of PVC board will decrease with the increase of temperature. Its thermal deformation temperature is low, it is easy to bend and deform when exposed to...
