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 seasoning, the density of the product , The hardness will also increase, while the toughness will decrease, the edge of the product will easily become brittle, and it will easily cause damage during processing and transportation

Abstract

The invention provides a middle material layer of a plastic floor and the plastic floor obtained by the same. The middle material layer of the plastic floor is prepared from the following raw materials in parts by weight: 90-95 parts of polyvinyl chloride, 28-33 parts of a plasticizer, 2.1-3 parts of a stabilizer, 0.2-0.5 part of carbon black, 455-465 parts of calcium carbonate and 6.2-10.5 parts of chlorinated polyethylene. A certain amount of chlorinated polyethylene is added into the formula of the middle material layer, the chlorinated polyethylene and the polyvinyl chloride have good compatibility, so that the toughness of the polyvinyl chloride is improved, the flexibility and the tensile force of the plastic floor product are improved, and the expansion rate and the shrinkage rate of the plastic floor are reduced; the weather resistance of the plastic floor is improved by using the high weather resistance of the chlorinated polyethylene, and thus the physical performance of the plastic floor is more excellent. In addition, the plasticizer adopts dioctyl terephthalate and is environment-friendly and non-toxic and long in thermal stable time, the plasticizer is prepared from natural oil, has the characteristics of fire resistance, no toxicity and environmental protection.

Description

technical field [0001] The invention relates to the field of plastic flooring, in particular to a middle material layer of the plastic flooring and the plastic flooring. Background technique [0002] Plastic floor is PVC floor, its main component is polyvinyl chloride material. PVC flooring is widely used in all aspects of home and business because of its rich patterns and diverse colors. Plastic flooring is a new type of light-weight floor decoration material that is very popular in the world today, also known as "light-weight floor material". It is a popular product in Europe, America, Asia, Japan and South Korea. It is popular abroad. It has entered the Chinese market since the early 1980s. It has been widely recognized in large and medium-sized cities in China and is widely used, such as indoor homes and hospitals. , schools, office buildings, factories, public places, supermarkets, businesses, stadiums and other places. [0003] In the existing plastic floor, in orde...
