Problems solved by technology

[0006] But even if the pressing process is adopted, floor tiles still have the weakness of being unable to withstand large impacts, especially for floor tiles mainly used on streets and roadsides, which are vulnerable to gravity impacts. Making high-impact floor tiles is an urgent problem to be solved both at home and abroad.

Abstract

The invention relates to a manufacturing method of high polymer environmental protection type plate material. The formula comprises of 10 to 30 parts of polyethylene recycled material by weight, 20 to 50 parts of other polyethylene recycled material by weight, 50 parts of quartz sand by weight and function material. The steps for manufacturing the plate material include: mixed material is produced by mixing the polyethylene recycled material and the function material; the mixed material is plasticized into a clinker at the temperature of 160 to 190 DEG C; the clinker produced during the step 2 is mixed with the quartz sand at the temperature of 120 to 160 DEG C, which is quantitatively discharged at constant temperature, and is made into semi-finished material; and the semi-finished material is pressed for 5 to 60 seconds with high pressure though a 100 to 300 tons pressing machine, and is shaped at constant temperature. The invention has the advantages that the basic raw material adopts the polyethylene recycled material, thereby being of environment protection and saving, the basic raw material can be added into a stress network when the semi-finished material is pressed to be shaped, and is compounded into a whole with the semi-finished material, thereby the anti-impact intensity of the finished products is enhanced, and the excellent effect that a 7.2kg steel ball does not generate depression or cracks under the 1.2 meters falling-weight impact can be achieved, the surface has anti-slip performance and abrasion proof performance through the quartz sand added, and different function materials enable the products to have good weatherability, flame retardant resistant performance, and anti-static performance.

Description

technical field [0001] The invention relates to a manufacturing method of a polymer environment-friendly sheet, which relates to a process method for producing an anti-skid sheet by using industrial polyolefin recycled materials, and the use of the sheet prepared by the method. Background technique [0002] Environmentally friendly floor tiles made from waste polyolefin as floor tiles are enduring products on the market. Publication No. CN1042864 discloses a semi-rigid plastic floor. Waste polyethylene is used as raw material, and the filler is inorganic filler treated with coupling agent. After high-speed mixing, it is granulated, extruded into sheets, and punched into floor boards. [0003] Publication No. CN1203897 discloses an anti-skid and wear-resistant floor. The raw material is also plastic, and an appropriate amount of emery and quartz sand abrasives are added. Extrusion and calendering are used to make floors or floor tiles. [0004] However, in the production of ...
