Abstract

The invention relates to a low-foaming PVC crust plate material, which is prepared from a PVC template recovery material, calcium powder, stabilizing agents, filling materials, foaming regulators, foaming agents, pigments, polyethylene wax and wood powder. The proportioning of each ingredient of the low-foaming PVC crust plate material is reasonable, so that the prepared PVC crust plate material has the better nail holding force on wood screws than wood materials; the bending intensity and the room temperature impact intensity are better than those of wood materials; the adhesion connection iseasy; the anti-deformation capability is high.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a low-foaming PVC crust board. Background technique [0002] PVC crust foam board has excellent corrosion resistance, insulation, and certain mechanical strength; after secondary processing, it can be made into sulfuric acid (hydrochloric acid) tank (barrel box); medical empty needle frame, chemical process frame ; public toilet water tank; various special-shaped products and containers such as templates, decorative panels, exhaust pipes, and equipment linings for processed products. It is an ideal material for chemical industry, building materials, decoration and other industries. PVC crust foam board is also called PVC crust board. Its chemical composition is polyvinyl chloride. It is widely used in passenger cars, train car ceilings, box core layers, interior decoration panels, building exterior wall panels, and interior decoration. Panels, offices, residences, bu...
