Abstract

The invention discloses a PVC crusting foaming building template and a preparation method thereof. The PVC crusting foaming building template is prepared from the following raw materials: 100 kg of a PVC template recycled material, 75 kg of a waste ground material, 6 kg of a foaming regulator, 2.5 kg of a stabilizing agent, 0.3 kg of PE wax, 1 kg of white carbon black, 1 kg of nitrile rubber, 0.3 kg of a yellow foaming agent, 1 kg of a white foaming agent and 2 kg of ZB600, wherein the stabilizing agent is one selected from the group consisting of a barium-zinc composite stabilizing agent, a calcium-zinc composite stabilizing agent and a lead-salt composite stabilizing agent; the foaming regulator is an acrylate processing additive; and the waste ground material is a plant straw ground powder. According to the invention, a proper amount of the nitrile rubber is adding into a formula, so the toughness of the template can be increased, and the problem of brittleness of the template in winter is solved; the white carbon black is added into the formula, so ultraviolet ray can be resisted, and the problem of easy deformation of the template in summer is solved; in addition, the plant straw ground powder is used as a filling material, so the themes of energy conservation and environmental protection at present are met.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a PVC-skinned foamed building formwork and a preparation method thereof. Background technique [0002] In the construction industry, the traditionally used formwork is basically wood formwork, but wood formwork is a loss of natural resources, and it is easy to rot, and the number of times of reuse is small, so it cannot be recycled again. Therefore, now wood formwork has basically been replaced by plastic formwork. replaced. In the initial stage of plastic formwork research, new raw materials such as resins and additives were basically used, resulting in high material and manufacturing costs. PVC crust foam building formwork is a representative of new materials. PVC crust foam building formwork is also called Chevron board and Andy board, its chemical composition is polyvinyl chloride, widely used in passenger cars, train car roof, box core layer, interior...
