Abstract

The invention discloses a PVC wood-plastic building material for heat insulation and water proofing of a building. The PVC wood-plastic building material is prepared by, by weight, 100-105 parts of polyvinyl chloride, 15-18 parts of kaolin, 30-35 parts of wood powder, 5-7 parts of carbonyl iron powder, 0.8-1.2 parts of blue copperas, 4-6 parts of nitrile rubber, 0.2-0.4 part of titanate coupling agent NDZ201, 0.4-0.6 part of silane coupling agent YH62, 3-4 parts of fatty acid soap, 5-6 parts of alundum powder, 6-7 parts of steel slag powder and 3-4 parts of olive oil. The PVC wood-plastic building material has high performance in the aspects of corrosion prevention, heat insulation, water proofing and fire proofing; the wood powder is high in filling quantity, and the PVC wood-plastic building material has good mechanical performance and high practicability.

Description

technical field [0001] The invention relates to the technical field of wood-plastic composite materials, in particular to a heat-insulating and waterproof PVC wood-plastic building material for buildings. Background technique [0002] As early as the 1940s, it was discovered that nitrile rubber and PVC were used together for research. Nitrile rubber has a certain polarity, and the solubility parameters of PVC are very close. They are both amorphous polymers. Good compatibility, so they are usually blended, and the alloy material obtained has excellent weather resistance, solvent resistance, good mechanical strength and processing performance, and is widely used in seals, wire and cable sheathing, Oil pipeline and other fields. The alloy materials of nitrile rubber and polyvinyl chloride are divided into cross-linked type and non-cross-linked type. The cross-linked alloy is insoluble and infusible, which is difficult to recycle and causes serious pollution to the environment...
