Stone-plastic lightweight vcp floor and preparation method thereof

Abstract

The invention relates to a composite floor, and in particular relates to a stone plastic light VCP floor and a preparation method thereof. The stone plastic light VCP floor is formed by compounding a color film, a wear-resistant layer and a VCP base material from top to bottom, wherein a main component of the wear-resistant layer is chlorinated polyethylene, and the wear-resistant layer is prepared from the following raw materials in percentage by mass: 64 to 75 percent of the chlorinated polyethylene, 15 to 20 percent of environment-friendly plasticizer, 3 to 4 percent of environment-friendly stabilizer, and 7 to 12 percent of light calcium carbonate; the VCP base material is prepared from the following raw materials in percentage by mass: 32 to 36 percent of polyvinyl chloride (PVC), 53 to 59 percent of composite calcium carbonate, 3 to 4 percent of environment-friendly stabilizer, 0.8 to 1.5 percent of lubricant, 0.5 to 1 percent of foamer, and 4 to 5 percent of processing agent. The stone plastic light VCP floor has no need of a PVC base material, and is convenient to mount, the overall density is about 0.95g / cm<3>, and the transportation cost is low.

Description

technical field [0001] The invention relates to a composite floor, in particular to a stone-plastic lightweight VCP floor and a preparation method thereof. Background technique [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 perform thermal compound 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 toler...

[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
