Embodiment 1

[0026] 1. Preparation of a PVC composite floor, (1) resin (35 parts), wood powder (30 parts), calcium powder (15 parts), silicon chloride powder (10 parts), graphite powder (6 parts), Polyurethane (4 parts) is added to the high-speed mixer, mixed and stirred for dehydration, and after stirring for about 20 minutes, the mixture is discharged from the mixer, and the material fineness reaches 280 mesh;

[0027] (2) Put the mixed material into the extruder. The temperature in the extruder is kept at 180°C. After the temperature rises, it enters the hydraulic press through the heat preservation box. The mold pressure in the hydraulic press is 500 tons, and it is made into PVC compound after passing through the cooling device. Floor planks.

[0028] 2. Floor production. First, the finished PVC composite floor is made into slats of the required specifications through cutting saws. The slat specification: 925×135×12mm; and then the slats are made by forming equipment (double-end milli...

Abstract

The invention belongs to the technical field of composite floors, relates to a composite floor, and in particular relates to a PVC composite floor and a preparation process thereof, and the PVC composite floor comprises the following main components by mass: 30-70 parts of PVC resin, 20-40 parts of wood flour, 10-30 parts of calcium chloride powder, 8-15 parts of chlorinated silica powder, 5-15 parts of graphite powder and 5-15 parts of polyurethane. The PVC composite floor has high hardness and good wear resistance, can be applied to indoor and outdoor environments, and does not contain formaldehyde. Because of the composition and structure characteristics, the hardness, wear resistance and other physical and chemical properties are better than those of solid wood floors. At the same time, due to the stable and compact molecular structure, the PVC composite floor has no pores on the product surface and has large product hardness, the PVC composite floor is corrosion-resistant, deformation-resistant and insect-resistant. The PVC composite floor has no formaldehyde additive in the production process, so that no formaldehyde is generated, and the PVC composite floor is more environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of composite floors, and relates to composite floors, in particular to a PVC composite floor and a preparation process thereof. Background technique [0002] At present, wooden flooring and ceramic tiles are the two most important building materials products in the domestic floor covering material market, with a market share of more than 95% in the floor covering material market. The advantages of wood flooring are strong wood feeling, beautiful texture effect, and good foot feel. However, with the development of social economy and the rapid increase of market demand, the contradiction between supply and demand of wood resources has become more and more obvious and prominent. As a synthetic material, ceramic tiles have the advantages of low cost of stone and sufficient supply of raw materials, but their disadvantages are also obvious: poor heat storage and human interaction, and not environmentally friendly....
