Abstract

The invention discloses a formula of a PVC separation wall composite board which comprises at least following ingredients: PVC resin, nano-calcium, calcium carbonate, an impact modifier, a calcium-zinc stabilizer, paraffin and stearic acid, and the weight ratio of the ingredients according to the formula is (30-70):(0-70):(0-70):(3-9):(1-5):(1-2):(1-6). According to the PVC separation wall composite board, the PVC main raw material is used, the material is easy to process and shape, the manufacturing cost is low, at the same time, the nano-calcium and/or calcium carbonate are/is added in the PVC main raw material, not only is the product volume increased, but also the cost is reduced; meanwhile, the impact modifier, the calcium-zinc stabilizer, the paraffin and the stearic acid are added to regulate the performance of the composite board, and the mechanical performance, the stability and the demolding effect of the composite board are enhanced; the preparation method of the composite board and the formula are in mutual combination in the production process, the production processes are regulated, no environment pollution is produced while the production efficiency is improved, andthe product yield is controlled.

Description

technical field [0001] The invention relates to the field of building wallboards, in particular to a stone-plastic partition wall composite board and a preparation method thereof. Background technique [0002] At present, the traditional red brick is still used as the main wall structure in the construction industry, but due to policy reasons, the red brick will withdraw from the construction market. Therefore, new wall material technologies continue to emerge to meet the new needs of the construction market. At present, in addition to clay bricks, there are also industrial waste slag block bricks, silicate and sulphoaluminate cement wallboards, etc. for building wall materials. The traditional clay solid brick, because of its serious waste of land resources, serious energy consumption, and serious pollution of the environment, at the same time, the construction project is not energy-saving, the construction labor intensity is high, the construction cost is high, the speed i...
