Problems solved by technology

[0002] At present, the VCP floor on the market is mainly composed of wear-resistant layer, color film, PVC base material, VCP base material, back pad material, etc., and the overall density is 1.3-1.4g / cm 3 Among them, the processing procedures are complicated. The production of VCP flooring must first produce PVC substrates, and then carry out thermal compounding treatment with wear-resistant layer and color film, and then perform surface UV, punching, lamination, cold pressing, slitting, and opening. Groove process, the entire production process consumes a lot of time, manpower and resources, and the complexity of the process leads to a decrease in the yield of the production link; because the current VCP floor is a multi-layer floor, it is not ideal in terms of thickness control. The cumulative tolerance between layers often exceeds the standard range, and the general deviation is between 0.15-0.25mm; in addition, since the upper part of the current VCP floor is made of PVC as the main material, and the upper PVC layer is stress-relieved by heat treatment, the upper layer The heating shrinkage rate of the floor is much smaller than the shrinkage rate of the lower VCP base material, so the heating warpage of the floor is more serious during the use process

Embodiment 1-3

[0033] The preparation method of lightweight VCP flooring includes PVC layer processing, VCP base material processing, bonding, cold pressing, surface UV treatment and slotting processes, as follows:

[0034] 1. Processing of PVC layer: mainly thermal compound processing, the prepared wear-resistant layer and printed color film are stacked on the carrying plate of the flat vulcanizer, the temperature is set at 120-150°C, and after thermal compounding for 10-20 minutes Release the mold, complete the thermal lamination of the wear-resistant layer and the printed color film, and wait for lamination. Among them, the thickness of the wear-resistant layer is 0.5mm, and the thickness of the color film is 0.07mm.

[0035] Preparation of the wear-resistant layer: the formula of the wear-resistant layer is shown in Table 1. Put the raw materials into a high-speed mixer and mix them at a speed of 1500 rpm. After 5-6 minutes, the materials are fed to the planetary machine, and the materia...

Abstract

The invention relates to a composite floor, in particular to a light VCP floor and a preparation method thereof. The light VCP floor is composited by a color film, an abrasion-resistant layer and a VCP base material from top to bottom. The main component of the abrasion-resistant layer is chlorinated polyethylene. The abrasion-resistant layer comprises the raw materials, by mass, of 64%-75% of the chlorinated polyethylene, 15%-20% of environment-friendly plasticizers, 3%-4% of environment-friendly stabilizers and 7%-12% of light calcium carbonate. The VCP base material comprises the raw materials, by mass, of 32%-36% of polyvinyl chloride, 53%-59% of composite calcium carbonate, 3%-4% of environment-friendly stabilizers, 0.8%-1.5% of lubricants, 0.5%-1% of foaming agents and 4%-5% of processing agents. According to the light VCP floor, a PVC base material is not needed, the overall density is 0.95 g / cm<3> or so, installation is simple and convenient, and transportation cost is low.
