Abstract

The invention discloses a low-size-shrinkage WPC floor and a preparation method thereof. The low-size-shrinkage WPC floor is formed by compounding a laminated structure composed of a skin, a WPC base material and cork wood from top to bottom in sequence, wherein the WPC base material comprises the following preparation raw materials by weight: PVC resin, glass fiber, montmorillonite, dioctyl terephthalate, an acrylic acid derivative, alkyl sodium sulfonate, a foaming agent, a stabilizer, stone powder and a coloring agent. The glass fiber reinforced WPC base material is prepared by adding the glass fiber, due to the characteristics of the glass fiber, the deformability of the WPC base material can be obviously improved, the heat resistance of the WPC base material is improved, for example, the size shrinkage rate of the WPC base material is improved, the heat warping performance of the base material is improved, and finally the glass fiber reinforced WPC base material can be added to the WPC floor, so that the WPC floor has the heat-resistant characteristic close to that of an SPC floor on the premise that the density is reduced.

Description

technical field [0001] The invention relates to the field of preparation of a low-size shrinkage floor, in particular to a low-size shrinkage WPC floor and a preparation method thereof. Background technique [0002] As a new type of floor covering material, PVC floor has excellent wear resistance, decoration, stain resistance and chemical reagent resistance, so it is more and more popular and recognized by consumers. The traditional hard PVC floor not only has excellent dimensional stability, high locking strength, mildew resistance, moisture resistance, insect resistance, convenient and quick installation, etc., it is very popular in developed countries in Europe and the United States and in the Asia-Pacific market. [0003] The industry is also constantly looking for new floor materials to replace, but the traditional SPC hard floor has the disadvantages of thick texture and high density; although the WPC floor has a low density, its physical properties are not as good as ...
