preparation example Construction

[0016] A preparation method for a WPC floor, comprising the WPC floor described above, comprising the following steps in turn:

[0017] Step 1: Add PVC resin powder, regulator, stabilizer, internal lubricant, PE wax, oxidized wax, and foaming agent into the professional mixer for mixing and stirring, and gradually add the reinforcing agent during the mixing and stirring process, and stir The time is 15 to 20 minutes, and the stirring temperature is 100°C to 115°C;

[0018] Step 2: Add stone powder to the mixture mixed in the step and stir for the second time. The stirring time is 40-60 minutes, and the stirring temperature is 59°C-65°C;

[0019] Step 3: Extrude the raw material stirred in Step 2 through a twin-screw extruder to form a plate, and then cool and shape it.

[0020] The WPC floor is prepared by the first raw material mixing and stirring, the second raw material mixing and stirring, extrusion, cooling and shaping, so that the shrinkage rate of the WPC floor in the ...

Abstract

The invention relates to a WPC floor which comprises the following components in parts by weight: 73.85-78.04 parts of PVC resin powder, 73.51-77.49 parts of stone powder, 10.12-15.71 parts of regulator, 4.12-4.95 parts of stabilizer, 3.87-4.21 parts of reinforcing agent, 0.47-0.82 parts of internal lubricant, 0.58-0.92 part of PE wax, 0.8-1.2 parts of oxidized paraffin and 1.18-1.55 parts of foaming agent. The invention has the advantages that the WPC floor is prepared from PVC resin powder, stone powder, regulator, stabilizer, reinforcing agent, internal lubricant, PE wax, oxidized paraffinand foaming agent; the environment-friendly nontoxic and odorless renewable resource of the PVC resin powder is capable of guaranteeing the overall environment-friendly effect and excellent plasticityof the WPC floor, 100% recycling of the WPC floor and no air pollution or environmental pollution caused by the WPC floor; the invention also discloses the WPC floor and the preparation method of theWPC floor.

Description

technical field [0001] The invention relates to a WPC floor and a preparation method thereof. Background technique [0002] At present, there are many types of wood floors on the market, with different materials, including natural, reinforced composite, and the floors with better performance are considered to be reinforced composite wood floors. However, in the existing reinforced composite wood flooring on the market, the substrate layer is made of wood chips that are ground into wood fibers by a thermal grinder and then pressed into high-density fiberboard as the floor substrate. The adhesive used is urea-formaldehyde resin with formaldehyde as the main component. , Formaldehyde is a harmful substance to the human body, and the residual free formaldehyde in the board will gradually release to the surrounding environment, which is the main body of indoor air pollution. , furniture, logistics packaging and other industries; at present, in our country's existing technology, ...
