Abstract

The invention discloses a preparation method of an environment-friendly door and window material. The environment-friendly door and window material is prepared from the following raw materials in parts by weight: 30 to 35 parts of modified PVC (Polyvinyl Chloride), 16 to 18 parts of bamboo shavings, 2 to 4 parts of glass fibers, 0.7 to 0.9 part of heat-resistant modifier, 0.3 to 0.4 part of stabilizer, 3 to 5 parts of calcium carbonate powder as well as proper amounts of tannin adhesive, titanium dioxide and nano-zinc oxide. The preparation method comprises the following steps: taking chloroethylene as a monomer, 5-mercaptopropyltriethoxysilane as a cross-linking agent and sodium carboxymethyl as a graft copolymer and preparing the modified PVC by using a suspended emulsion method; then mixing the modified PVC with the bamboo shavings, the glass fibers, calcium carbonate, the heat-resistant modifier and the stabilizer and carrying out hot-pressing, thus obtaining the environment-friendly door and window material.

Description

technical field [0001] The invention relates to a preparation method of an environment-friendly door and window material. Background technique [0002] The development of PVC plastic profiles has been a very mature product up to now. The product categories include PVC plastic door and window profiles, PVC exterior wall hanging panels, PVC synthetic resin tiles, PVC guardrails and other outdoor products. PVC plastic has the advantages of good rigidity, high strength, flame retardancy, and good electrical insulation. However, because of the poor degradation performance of PVC, polyethylene with a low degree of polymerization will cause certain harm to the human body after decomposition, and the environmental protection performance needs to be improved. In the prior art, there is a method of copying PVC materials and wood into door and window materials. This method can reduce the amount of PVC used, improve dimensional stability and degradation performance, and realize the util...
