Antiseptic wood-plastic material and preparation method thereof

Abstract

The invention provides an antiseptic wood-plastic material and a preparation method thereof. The antiseptic wood-plastic material is prepared by the following steps and prepared from the following rawmaterials in parts by weight: 30 to 60 parts of sawdust powder, 20 to 50 parts of resin, 5 to 15 parts of modified basalt fiber, 0.1 to 1 part of a heat stabilizer, 0.1 to 1 part of a lubricant, 0.1to 1 part of a solubilizer, 1 to 5 parts of nano zinc oxide and 1 to 2 parts of a mildew preventive, wherein the mildew preventive is prepared from the following raw materials in parts by weight: 5 to15 parts of nano zinc oxide, 5 to 10 parts of nano silicon dioxide, 5 to 10 parts of gallotannic acid, 1 to 3 parts of triethanolamine, 1 to 5 parts of an aluminate coupling agent, 1 to 5 parts of white mineral oil, 1 to 3 parts of olive oil, 1 to 3 parts of litsea cubeba oil, 0.5 to 1.5 parts of palmitic acid and 2 to 5 parts of glycerin monostearate. According to the antiseptic wood-plastic material disclosed by the invention, the sawdust powder and the resin are utilized as the main materials; by means of adding the modified basalt fiber, nano calcium carbonate and the mildew preventive, apreservative effect of the wood-plastic material is improved.

Description

technical field [0001] The invention relates to the technical field of wood-plastic materials, in particular to an antiseptic wood-plastic material and a preparation method thereof. Background technique [0002] Wood-plastic, that is, wood-plastic composite material, is a new type of composite material that has been booming at home and abroad in recent years. It refers to the use of polyethylene, polypropylene and polyvinyl chloride, etc. Waste plant fibers such as powder, rice husk, straw, etc. are mixed into new wood materials, and then plastic processing processes such as extrusion, molding, and injection molding are used to produce boards or profiles. It has the advantages of long service life, beautiful appearance, renewable, low cost, anti-slip, sprayable, higher hardness than pure plastic products, and can be processed, bonded and fixed like wood, especially when using waste plastic and wood When the processing residue or straw is used as the main raw material, it al...

Problems solved by technology

[0005] Because wood-plastic composites are filled with a large amount of plant fibers, even though they are covered by plastic, they can still provide a good living environment for fungi under certain humid conditions, resulting in mildew and decay of wood-plastic composites, thereby shortening the service life.

In addition, mildew will cause mold spots visible to the naked eye on the surface of wood-plastic composite materials, which will affect its appearance.
