Problems solved by technology

[0003] The added material in the rigidity of traditional elastic floors is mainly calcium carbonate, which has insufficient surface smoothness, which affects the aesthetics of the product to a certain extent
At the same time, there are still the following problems: 1. The strength performance of the product is insufficient, mainly reflected in the static bending strength and elastic modulus, which affects the performance and application range of the product
2. The production cost of the product is high
3. The density of the product is high, and there is some inconvenience in the process of transportation and installation, which affects the overall cost and work efficiency

Abstract

The invention relates to a high-strength low-density floor and a preparation method thereof, belonging to the field of indoor floor covering materials. The high-strength low-density floor of the present invention comprises a base material, a color film layer, a wear-resistant layer, and an anti-ultraviolet coating layer in sequence, and the base material includes kaolin. The high-strength low-density floor of the present invention greatly improves strength properties such as static bending strength and elastic modulus, and has excellent strength properties. Its static bending strength can reach more than 25 MPa, and the elastic modulus can reach more than 4500 MPa. The static bending strength of similar floors is 20-25MPa, and the elastic modulus is 4000-4500MPa.

Description

technical field [0001] The invention relates to a high-strength low-density floor and a preparation method thereof, belonging to the field of indoor floor covering materials. Background technique [0002] At present, elastic floor and wall panel products have been widely used in the market, and they are a kind of decorative products with good development prospects. Among them, elastic 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 material". It is a popular product in Europe, America, Asia, Japan and South Korea. It began to enter the Chinese market in the early 1990s, and has been widely recognized in large and medium-sized cities in China, and is widely used, such as homes, hospitals, schools, office buildings, factories, public places, supermarkets, commercial places and other places. Specifically, polyvinyl chloride and its copolymer resin are used as the main raw materials, and fi...
