    Abstract

    The present disclosure provides a rigid high-gloss wear-resistant and scratch-resistant flooring. The flooring includes a surface layer, an intermediate Spc layer, and a decorative layer that are laminated; where the surface layer is prepared by combining a melamine glue and a color film; the intermediate Spc layer is prepared by mixing polyvinyl chloride resin, calcium carbonate, a plasticizer, and a stabilizer; and the decorative layer is prepared by a high-temperature material. The rigid high-gloss wear-resistant and scratch-resistant flooring is prepared by the melamine glue and the special color film, has an intermediate Spc layer, and has the decorative layer on a back side. The flooring is prepared by three different layers through a high temperature and a high pressure. The flooring has a surface that is highly wear-resistant, extremely scratch-resistant, cigarette burning-resistant, and non-deformable, and is suitable for use in various public places, with various styles, diverse specifications, and stability.

    Claims

    1. A rigid high-gloss wear-resistant and scratch-resistant flooring, comprising a surface layer, an intermediate Spc layer, and a decorative layer that are laminated; wherein the surface layer is prepared by combining a melamine glue and a color film; the intermediate Spc layer is prepared by mixing polyvinyl chloride (PVC) resin, calcium carbonate, a plasticizer, and a stabilizer; and the decorative layer is prepared by a high-temperature material.

    2. The rigid high-gloss wear-resistant and scratch-resistant flooring according to claim 1, wherein a preparation method of the intermediate Spc layer comprises the following steps: conducting homogenization on the PVC resin, the calcium carbonate, the plasticizer, and the stabilizer by mixing with a high-speed mixer; conducting radial mixing and partially-axial mixing in a cold mixer under the action of a slowly rotating stirring paddle, to reduce a temperature of an obtained mixed powder; discharging the mixed powder from a discharge port of a mold by a twin-screw extruder when the mixed powder is cooled to not greater than 45° C., and conducting calendering, cooling, and shaping.

    3. The rigid high-gloss wear-resistant and scratch-resistant flooring according to claim 2, wherein the PVC resin, the calcium carbonate, the plasticizer, and the stabilizer are mixed by the mixer at 80° C. to 90° C. for 10 min, and then at 100° C. to 120° C. for 15 min, and then at greater than 120° C. for 5 min.

    4. The rigid high-gloss wear-resistant and scratch-resistant flooring according to claim 1, wherein the decorative layer is formed by pressing into a large sheet by a hot press under a high temperature and a high pressure, and then cutting.

    Description

    DETAILED DESCRIPTION OF THE EMBODIMENTS

    [0015] In order to make the objectives, technical solutions and advantages of the examples of the present disclosure more apparent, the technical solution of the examples of the present disclosure will be described clearly and completely below. In order to keep the following description of the examples of the present disclosure clear and concise, the present disclosure omits detailed descriptions of well-known functions and well-known components so as not to unnecessarily obscure the concept of the present disclosure.

    [0016] A rigid high-gloss wear-resistant and scratch-resistant flooring included a surface layer, an intermediate Spc layer, and a decorative layer that were laminated; where

    [0017] the surface layer is prepared by combining a melamine glue and a color film;

    [0018] A preparation method of the intermediate Spc layer included the following steps: homogenization was conducted on PVC resin, calcium carbonate, a plasticizer, and a stabilizer by mixing with a high-speed mixer at 80° C. to 90° C. for 10 min, and then at 100° C. to 120° C. for 15 min, and then at greater than 120° C. for 5 min; radial mixing and partially-axial mixing were conducted in a cold mixer under the action of a slowly rotating stirring paddle, to reduce a temperature of an obtained mixed powder; and the mixed powder was discharged from a discharge port of a mold by a twin-screw extruder when the mixed powder was cooled to not greater than 45° C., and calendering, cooling, and shaping were conducted.

    [0019] The decorative layer was prepared by a high-temperature material, and then formed by pressing into a large sheet by a hot press under a high temperature and a high pressure, and then cutting.

    [0020] As was seen in Table 1:

    TABLE-US-00001 Standard requirement Testing requirement Standard value Tolerance (mm) Test results Unit Result determination Effective area length (mm) 1220 ±0.5 1220 mm Qualified Effective area width (mm) 180 ±0.1 180 mm Qualified Thickness (mm) 4.0 ±0.15 4.05 mm Qualified Squareness (mm) 0 ≤0.20 0 mm Qualified Straightness (mm) 0 ≤0.20 0.00 mm Qualified

    [0021] As was seen in Table 2:
