preparation example Construction

[0044] The present invention provides a kind of preparation method of wood-plastic floor, comprises the following steps:

[0045] Melting and extruding the components included in the base material to obtain the base material;

[0046] A tough layer, a balance layer, a decorative layer and a wear-resistant layer are provided, and a base material, a tough layer, a decorative layer and a wear-resistant layer are sequentially arranged on the balance layer to obtain a wood-plastic floor.

[0047] The present invention has no special limitation on the components of the base material, and the base material well-known to those skilled in the art for preparing wood-plastic flooring can be used. In order to obtain the wood-plastic floor with antibacterial and antiviral properties, in parts by weight, preferably 30.0 to 50.0 parts of modified plant powder, 100 parts of polyvinyl chloride, 30.0 to 50.0 parts of calcium carbonate, 5.0 to 7.0 parts 1 part of the first composite stabilizer,...

Embodiment 1

[0108] Add 30.0 parts of wood powder with a fineness of 60 meshes into the mixer and start the operation. When the temperature rises to 100°C, open the cover and stop, and add silane coupling agent with 1.1% of the wood powder mass into the mixer within 3 minutes. In the middle, after starting up for another 3 minutes, put the obtained material into the cold mixer to run, and the temperature drops below 45°C to obtain modified wood powder;

[0109] The modified sawdust powder is mixed with 100 parts of polyvinyl chloride, 30.0 parts of activated calcium carbonate with a fineness of 600 meshes, 2.0 parts of calcium stearate, 3.0 parts of tribasic lead sulfate, 10.0 parts of foam regulator, 1.0 parts of even Nitrogendiformamide, 3.0 parts of chlorinated polyethylene (CPE), and 3.0 parts of polyethylene wax were added to the mixer, and the mixing temperature was adjusted to 110°C. Five minutes before the end of the temperature rise, 5.0 parts of 60-mesh Put it into the mixer, and...

Embodiment 2

[0129] Add 50.0 parts of wood powder with a fineness of 80 meshes into the mixer and start the operation. When the temperature rises to 110°C, open the cover and stop, and add 1.3% silane coupling agent of wood powder into the mixer within 5 minutes. In the middle, after starting up for another 3 minutes, put the obtained material into the cold mixer to run, and the temperature drops below 45°C to obtain modified wood powder;

[0130] Mix the modified sawdust powder with 100 parts of polyvinyl chloride, 50 parts of activated calcium carbonate with a fineness of 1200 mesh, 3.0 parts of zinc stearate, 4.0 parts of dibasic lead phosphate, 16.0 parts of foam regulator, 0.8 parts of even Nitrogendiformamide, 4.0 parts of chlorinated polyethylene (CPE), and 6.0 parts of polyethylene wax were added to the mixer, and the mixing temperature was adjusted to 110 ° C. 4 minutes before the end of the temperature rise, 10.0 parts of 80-mesh Put it into the mixer, and then turn it on for 5 m...

Abstract

The invention provides a wood-plastic floor. The wood-plastic floor comprises a balance layer, a base material arranged on the balance layer, a tough layer arranged on the base material, a decoration layer arranged on the tough layer, and an anti-abrasion layer arranged on the decoration layer. Compared with the prior art, the wood-plastic floor comprises the tough layer arranged between the base material and the decoration layer, and due to the additional arrangement of the tough layer, the mechanical property of the wood-plastic floor is improved. The result shows that the bending failure load of the wood-plastic floor obtained through the first embodiment of the invention is 2325, the size change rate of the wood-plastic floor obtained through the first embodiment of the invention is 0.2 after heating is conducted, and the change rate of the sizes of the two faces of the wood-plastic floor obtained through the first embodiment of the invention is 0 after heating is conducted.

Description

technical field [0001] The invention relates to the technical field of floor processing, in particular to a wood-plastic floor and a preparation method thereof. Background technique [0002] Wood-plastic flooring is a new type of environmentally friendly wood-plastic composite material product, which is mainly composed of wood powder (plant fiber) and thermoplastic polymer materials and processing aids, etc., mixed evenly and then heated and extruded by mold equipment. The high-tech green environmental protection material has both the performance and characteristics of wood and plastic, and can replace wood and plastic as a new environmentally friendly high-tech material. Wood-plastic flooring is a floor made of wood-plastic composite materials. It has the same processing characteristics as wood. It can be sawed, drilled, and nailed with ordinary tools. Nailing is very convenient and can be used like ordinary wood. At the same time, it has the woody feeling of wood and the ...
