Abstract

The invention belongs to the field of buildings, and concretely relates to a PVC building template and its preparation method. The mainly PVC building template is made by using PVC resin and alkali-free ground glass fibers as main materials and using a foaming regulator HL-100, a lubricant ZB-601, a lubricant AP, a white foaming agent NC, a yellow foaming agent AC, a plasticizer, a calcium powder filler CaCO3 and a stabilizer as auxiliary materials. The making method comprises the steps of main material and the auxiliary material blending, extrusion forming, traction and product cutting. The PVC building plate has the advantages of improved hardness, enhanced impact resistance, improvement of the stability of the PVC resin, and increased heat deformation resistance temperature.

Description

technical field [0001] The invention relates to the construction field, in particular to a PVC building formwork and a preparation method thereof. Background technique [0002] At present, in the traditional construction industry, bamboo plywood is generally used to cast cement walls, facades and pools, etc. During the construction process of bamboo plywood, the construction process is complicated, time-consuming and labor-intensive, and paint must be painted on the wall. Increased production costs. [0003] Aiming at some problems caused by the above-mentioned bamboo plywood as a building formwork, the patent application number is 201110307112.8, and the Chinese invention patent with the application date of 2011.10.12 discloses a panel of a combined PVC building formwork and its preparation method, which mainly uses PVC Resin SG-51 is the main material, using calcium zinc stabilizer, light CaCO 3 , DuPont titanium dioxide, impact modifier, ultraviolet light absorber, and ...
