Problems solved by technology

[0003] In the existing plastic floor, in order to control the expansion rate and shrinkage rate of the product, a large amount of inorganic filler (calcium carbonate) is added, but adding a large amount of inorganic filler will bring new problems. With the increase of inorganic filler, the density of the product, The hardness will also increase, while the toughness will decrease, and the edges of the product will easily become brittle, which will easily cause damage during processing and transportation

Abstract

The invention discloses an LVT plastic floor. The LVT plastic floor is prepared from raw materials in parts by weight as follows: 50-100 parts of PVC resin powder, 100-200 parts of heavy calcium carbonate, 1-5 parts of a plasticizing modifier, 2-6 parts of an environment-friendly stabilizer, 1-3 parts of a lubricant and 0.2-0.5 parts of carbon black. The invention also discloses a preparation method of the LVT plastic floor. The method comprises the steps as follows: the raw materials are mixed, stirred and placed in an internal mixer to be stirred and heated to 100-120 DEG C, the obtained mixture is continuously stirred in a roller, discharging and cooling are performed, and an intermediate is formed; the intermediate is sequentially subjected to hot-pressing lamination with a color filmand an anti-wear layer, a floor obtained after hot-pressing lamination is coated with a UV coating through roller coating to be cured, and the cured floor is sent to a cutting press to be cut; the LVTplastic floor is obtained. The LVT plastic floor prepared with the formula is softer in texture, waterproof and damp-proof, has very high impact resistance and well restore elasticity under the impact of weights. The production technology of the LVT plastic floor is simple, raw materials are cheap, and the LVT plastic floor can be completely recovered after being used for several years.

Description

technical field [0001] The invention belongs to the technical field of plastic flooring. More specifically, it relates to an LVT plastic floor and a preparation method thereof. Background technique [0002] Traditional ceramic flooring, solid wood flooring, and composite flooring have phenomena such as cold feet, easy deformation, and excessive formaldehyde, which can no longer meet people's requirements. There is an urgent need for a soft, non-deformable and environmentally friendly indoor floor. LVT plastic floor, also known as PVC floor, came into being to meet people's needs; the main component of PVC floor is polyvinyl chloride material. PVC flooring is widely used in all aspects of home and business because of its rich patterns and diverse colors. LVT plastic floor is a new type of light-weight floor decoration material that is very popular in the world today, also known as "light-weight floor". It is a popular product in Europe, America, Asia, Japan and South Korea...
