Embodiment 1

[0038] A stone-crystal composite floor, comprising a wear-resistant layer 1, a color film layer 2, a PVC-impregnated glass fiber layer 3, and a substrate layer 4 arranged sequentially from top to bottom; the thickness of the PVC-impregnated glass fiber layer 3 is 0.10mm . The wear-resistant layer 1 is a PMMA film.

[0039] The base layer 4 is made of the following raw materials in parts by weight: 200 parts of filler, 50 parts of PVC resin, 2 parts of internal lubricant, 1.5 parts of external lubricant and 10 parts of stabilizer.

[0040] In this example, the added CPE resin is partially chlorinated high-density polyethylene with a chlorine content of 25% to 35%. CPE resin has the advantages of economical price and good processability, and can be used as an impact modifier for CPVC In the process of processing; compared with PVC, due to the increase of chlorine content, the intermolecular polarity and brittleness of CPVC increase, so a certain amount of impact modifier needs ...

Abstract

A stone crystal composite floor comprises a wear-resistant layer, a color film layer, a PVC impregnated glass fiber layer and a base material layer which are sequentially arranged from top to bottom; the base material layer is prepared from, by weight, 150-200 parts of a filler, 25-50 parts of PVC resin, 0.5-2 parts of an internal lubricant, 0.5-1.5 parts of an external lubricant and 5-10 parts of a stabilizer, the length-diameter ratio of the filler is n, the length of the filler is m, n is more than or equal to 4 and less than or equal to 20, and m is more than or equal to 5 microns and less than or equal to 25 microns; and due to the adoption of the filler with the length-diameter ratio, the floor has excellent dimensional stability when coping with a complex temperature environment.

Description

technical field [0001] The invention relates to the technical field of floor boards, in particular to a stone crystal composite floor and a preparation method thereof. Background technique [0002] Stone crystal flooring is a new type of flooring, which is currently popular in European and American countries, and has a very broad domestic market prospect. Stone crystal floor mainly uses calcium powder and other minerals that can be directly obtained from nature as the main raw material. It is composed of transparent layer, wear-resistant layer, color film layer, base material layer, and rebound layer. It is very suitable for home flooring. Among them, the transparent layer, wear-resistant layer and color film layer account for about 10% of the volume of the whole product. The material of the whole product is mainly a co-extruded base material layer formed by PVC resin and mineral powder. [0003] Due to the low softening point of PVC resin, which is between 72 and 82 °C, th...
