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 and low-density floor and a preparation method thereof, and belongs to the field of indoor ground paving materials. The high-strength and low-density floor sequentially comprises a base material, a color film layer, a wear-resistant layer and an ultraviolet-proof coating layer, and the base material comprises kaolin. According to the high-strength and low-density floor, the strength performances such as the static bending strength and the elastic modulus are greatly improved, the high-strength and low-density floor has excellent strength performance, the static bending strength can reach 25 MPa or above, the elastic modulus can reach 4500 MPa or above, and the static bending strength and the elastic modulus of existing similar floors are 20-25 MPa and 4000-4500 MPa respectively.

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...
