Problems solved by technology

Although it has the advantages of anti-corrosion and waterproof, it has poor aging resistance, is easy to fade, and its mechanical properties gradually decrease with aging, which affects its service life.
At the same time, wood-plastic composite flooring also has disadvantages such as a larger proportion than wood, high raw material and production costs, and wear resistance, which leads to the fact that the outdoor application of wood-plastic composite materials is not very popular.
There is a multi-layer plastic-wood composite material board, such as patent CN103818072A, its surface layer is composed of polyethylene, modified wood powder, maleic anhydride grafted polyethylene, etc., because the plastic used is ordinary polyethylene, low molecular weight, not wear-resistant and aging resistance, resulting in poor surface wear resistance and aging resistance of the plate

Embodiment 1

[0024] According to the wear-resistant floor of the co-extruded polymer composite material of the present invention, the surface layer 1 includes the following materials in weight percentage: 95% of ultra-high molecular weight polyethylene powder with a viscosity-average molecular weight of 1.50-4.5 million, 1% of polyethylene wax, iron oxide Palm 4%; core layer 2 includes the following materials in weight percentage: waste polyethylene 40%, wood powder 6%, fly ash 45%, ultrafine activated calcium carbonate 6%, azodicarbonamide 0.7%, DCP0.3 %, Zn01%, polyethylene wax 1%.

[0025] The preparation method is as follows:

[0026] (1) Weigh the surface layer raw materials in proportion and add them to the high-speed mixer. After high-speed mixing for 7-10 minutes, they are discharged into the surface layer storage bin, and automatically loaded to the Φ45 type ultra-high molecular weight polyethylene for surface layer processing by the spring feeder. In the hopper of a special sing...

Abstract

The invention relates to a co-extrusion polymer composite wear-resisting floor and a preparation method thereof. The floor is composed of a surface layer and a core layer, wherein the surface layer is located on the upper surface of the core layer and upper half parts of the two sides and is 1.5-2.0 mm thick. The surface layer and the core layer are continuously formed at a time through co-extrusion lamination. The surface layer is made of UHMWPE, polyethylene wax and inorganic colorants, and the core layer is composed of waste polyethylene, wood flour, coal ash, foaming nucleating agents, foaming agents, cross-linking agents, blowing promoter and polyethylene wax. The composite wear-resisting floor has the advantages of being light, high in strength, resistant to wearing, resistant to aging and low in cost.

Description

technical field [0001] The invention relates to the technical field of materials used in municipal administration, gardening, outdoor decoration, etc., in particular to a wear-resistant floor made of co-extruded polymer composite material and a preparation method thereof. Background technique [0002] At present, anti-corrosion wood, solid wood floor or wood-plastic composite floor are usually used in the market for municipal, garden, villa outdoor floors, guardrails, fences, pavilions, etc. Anti-corrosion wood and solid wood floors need to consume a lot of wood and are expensive. Although they also have the advantages of wear resistance, they have poor water resistance and corrosion resistance after laying and use, and are easy to crack and warp. Wood-plastic composite flooring is made of wood chips and waste plastics by mixing and extruding. Although it has the advantages of anti-corrosion and waterproof, it has poor aging resistance, is easy to fade, and its mechanical p...
