Abstract

A high-strength impact-resistant weather-resistant PVC building board is made mainly from the following raw materials, by weight part, 100 parts of polyvinyl chloride, 5-80 parts of chlorinated polyvinyl chloride, 5-60 parts of straw fiber powder, 2-15 parts of a toughening agent, 5-100 parts of a functional filling material, 3-6 parts of a stabilizer, 0.2-3.0 parts of a foaming agent, 3-12 parts of a foaming conditioning agent, 0.3-2.0 parts of an inner lubricant and 0.3-2.0 parts of an outer lubricant. Through addition of the functional filling material, the system is stable during PVC foaming, and thermal resistance and aging resistance of the board are obviously improved. The corrosion resistance of the foamed material is obviously improved, so that the application field of the product is widened. The strength and impact resistance of the board is superior to a PVC foamed board in the market at the present. Crop straw powder instead of conventional wood powder is utilized, so that the forest resources are saved and the problem of straw burning is solved.

Description

technical field [0001] The invention relates to the application of new materials and PVC biomass materials, in particular to a high-strength impact-resistant and weather-resistant PVC building board and a preparation method thereof. Background technique [0002] PVC building board is an environmentally friendly product, and the processing technology is very mature. The material can be recycled and reused. It can bring better economic and social effects in terms of promoting resource recycling, energy saving and emission reduction, and sustainable economic development. However, compared with the wooden building templates on the market, the existing PVC building boards still have disadvantages such as high production cost, low cost performance, easy deformation under high temperature in summer, fragile and easy to crack during construction in cold regions, and lead to less reuse times, etc., thus limiting its area of ​​application. my country is a country with a large demand ...
