Problems solved by technology

[0003] The traditional insect control method for indoor furniture mostly uses chemically synthesized pyrethroid insect repellent. Although the insect repellant is effective, in some specific occasions, such as hotels, due to safety considerations, the window openings are small, and the indoor ventilation effect is very poor. , these chemical components will remain in a large amount indoors and cause certain harm to the human body, so it is necessary to study a composite floor surface material with an insect-proof effect

Abstract

The invention provides a preparation method for an anti-insect surface material of a hard plastic-wood composite floor. The surface material mainly comprises talcum powder, sarin resin, wood powder, maleic anhydride-grafted polyethylene, a lubricant, an anti-oxidant, an ultraviolet ray absorber, a natural plant-modified insect repellant and HDPE. The surface material is good in bonding performance, not prone to delamination, resistant to wear, corrosion, skidding, ultraviolet rays and ageing and capable of repelling insects. The surface of the surface material can be subjected to sanding, embossing, polishing, drawing, etc. After molding of the surface material, wood-imitating effect, stone-imitating effect and the like can be obtained after processing, and the surface material is hard. Since cattail wool is used as a main component of the insect repellant, good insect-repelling effect and refreshing and tranquillizing effect are obtained.

Description

technical field [0001] The invention relates to the technical field of wood-plastic flooring, in particular to a method for preparing a hard plastic-wood composite floor surface material with an insect-proof effect. Background technique [0002] Wood-plastic composites (Wood~polymer Composites, abbreviated as WPC) is a new type of material that is made of wood fiber or plant fiber as the main component, which is combined with thermoplastic resin or other materials after pretreatment. This material can give full play to the advantages of each component in the material and overcome the shortcomings of a single material. It can not only improve the physical and mechanical properties and processing properties of the material, reduce costs and expand the application range, but also increase the added value of the material. Since the product is in a multiphase state of crystalline (wood fiber or plant fiber) and disordered state (resin), it has both the high strength and high hard...
