Problems solved by technology

However, the current heat resistance of PVC laminates cannot reliably meet the needs of long-term use under high temperature conditions. Usually, the Vicat softening point can only reach about 80°C. Therefore, the heat resistance of PVC laminates needs to be further optimized and improved.

Abstract

The invention discloses a heat-resistant PVC laminate, which comprises the following raw materials in parts by weight: 100 parts of PVC resin powder, 2-6 parts of stabilizer, 0.5-2 parts of lubricant, 12-36 parts of filler, 5 parts of heat-resistant agent ~20 parts; The present invention also provides the preparation method of described heat-resistant PVC laminated board; A kind of heat-resistant PVC laminated board provided by the present invention carries out single factor test and orthogonal test by the consumption of different components, and heat-resistant The performance of the PVC laminate is measured, and finally the test results are comprehensively analyzed to obtain the best raw material formula, which makes the raw material formula of the heat-resistant PVC laminate scientific and reasonable, and has strong heat resistance: the Vicat softening point is significantly increased; and the impact The strength and tensile strength have little change, meeting the requirements of the national standard.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a heat-resistant PVC laminated board and a preparation method thereof. Background technique [0002] PVC is one of the five major synthetic thermoplastics, its output is second only to polyethylene, and PVC is mainly hard products. PVC laminates are widely used in chemical industry, packaging and decoration industries, and are developing at a relatively fast speed. However, the heat resistance of the current PVC laminates cannot reliably meet the needs of long-term use under high temperature conditions. Usually, the Vicat softening point can only reach about 80°C. Therefore, the heat resistance of PVC laminates needs to be further optimized and improved. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, and provide a heat-resistant PVC laminated board, the Vicat softening point is obviously ...
