Problems solved by technology

[0004] However, in the humid south, due to the heavy humidity, the water vapor is very easy to condense, that is, the phenomenon of returning to the south sky. When the existing plastic wood materials come to the south sky season, the plastic wood door panels will be completely soaked, resulting in a greatly shortened service life of the plastic wood door panels.

Abstract

The invention discloses a plastic-wood material for a moisture-proof door board. The plastic-wood material comprises the following components in mass by parts: 50-60 parts of polyvinyl chloride,15-25parts of polypropylene,35-55 partsof rice husks, 40-55 parts of a filler, 1-4 parts of a compatibilizer, 0.8-2.5 parts of a lubricant, 2-4 parts of a coupling agent, 0.5-1.2 parts of an antiaging agent, and 3-7 parts of a dispersing agent. The door board produced from the plastic-wood material has the moisture-proof function, even in the season in which the temperature is increased and the moisture is increased, no water vapor and condensation water appear on the surface of the door board, thus avoiding the condition that a conventional plastic-wood material is soaked in the water to be wet, and then the service life of the conventional plastic-wood door board is greatly shortened.

Description

Technical field [0001] The invention relates to the field of plastic wood materials, in particular to a plastic wood material for moisture-proof door panels. Background technique [0002] Plastic wood is also called wood plastic, that is, wood plastic composite material, which is a new type of composite material that has flourished in recent years at home and abroad. [0003] Wood-plastic composite material contains plastic, so it has a good elastic modulus. In addition, because it contains fiber and is fully mixed with plastic, it has physical and mechanical properties such as compression resistance and bending resistance equivalent to hardwood, and its durability is significantly better than ordinary wood materials. The surface hardness is high, generally 2-5 times that of wood. [0004] However, in the humid south, due to the heavy humidity, the water vapor is very easy to condense, that is, the phenomenon of returning to the southern sky. When the existing plastic-wood material...
