Abstract

The invention discloses a PVC tile and a preparation method thereof. The PVC tile comprises a weather-proof modified layer and a PVC layer from top to bottom, wherein the PVC layer comprises the following compositions including a heat stabilizer, stearic acid, CPE, PE wax, paraffin, PVC powder, calcium powder, titanium dioxide and a pigment. The preparation method comprises the following steps ofsequentially adding the heat stabilizer, the stearic acid, the CPE, the PE wax, the paraffin, the titanium dioxide and the pigment in a stirring machine for premixing to obtain a premix; putting the premix, the PVC powder and the calcium powder in a hot stirring machine to be stirred uniformly to obtain a mixture; carrying out water cooling on the mixture obtained after hot stirring; adopting an extruder to extrude the cooled mixture out; compounding extrudate with the weather-proof modified layer to obtain a composite material; carrying out embossing and cooling on the composite material; andcarrying out die pressing and cutting forming to obtain the PVC tile. The weather-proof modified layer is thin and can save the cost; and by combining with the reasonable compositions, matching and the preparation technology of the PVC tile, the prepared PVC tile has excellent weatherability, waterproofness, load resistance and impact resistance.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a PVC tile and a preparation method thereof. Background technique [0002] PVC tiles use PVC as the main raw material, and the PVC surface is covered with an anti-aging layer (ASA / ABS / PMMA / ABS / PET, etc.). The existing anti-aging layer mostly uses ASA to improve the weather resistance and color of PVC tiles. Persistence: PVC tiles are rich in color, green and environmentally friendly, and have the advantages of light weight, waterproof, tough, sound insulation, acid and alkali resistance, corrosion resistance, heat insulation, and easy installation. They are widely used in door-type steel structure factories, chemical industry Plants, warehouses, coastal buildings and other fields are widely used in almost all industrial industries as well as breeding and decoration industries; especially suitable for roofing fields such as flat-to-slope conversion, villas, garden pavil...
