High-abrasion-resistance TPU stone plastic floor and preparation method thereof

Abstract

The invention relates to the technical field of floors, in particular to a high-abrasion-resistance TPU stone plastic floor and a preparation method thereof. The high-abrasion-resistance TPU stone plastic floor comprises a UV coating, a pure TPU abrasion-resistant layer, a color film, a PVC transparent layer, a PVC middle layer and a PVC bottom layer from top to bottom. The preparation method comprises the steps: (1) the following raw materials of a cover plate, canvas, a grained plate, an OPP film, a perforated PP film, the pure TPU abrasion-resistant layer, the color film, the PVC transparent layer, the PVC middle layer, the PVC bottom layer, an OPP high-temperature film, a shading plate, canvas and a bottom plate are sequentially laid from top to bottom; and (2) a film structure obtained in the step (1) is laminated to obtain the high-abrasion-resistance TPU stone plastic floor. The high-abrasion-resistance TPU stone plastic floor and the preparation method thereof have the beneficial effects that in the preparation method, a calendering process is used for producing a pure TPU thin film, and the efficiency is improved; and abrasion resistance of the obtained stone plastic flooris greatly improved, and low temperature resistance is better.

Description

technical field [0001] The invention relates to the technical field of floors, in particular to a highly wear-resistant TPU stone-plastic floor and a preparation method thereof. Background technique [0002] Stone-plastic flooring is popular among consumers because of its waterproof, wear-resistant, and long service life. It is generally composed of PVC (polyvinyl chloride) substrate layer, PVC middle layer, decorative layer, wear-resistant PVC layer, and UV paint. The layers are joined sequentially. The stone-plastic floor thus obtained has low strength, unstable product performance, and average surface wear resistance. [0003] TPU film is a functional film, which has the characteristics of high strength, good toughness, cold resistance, oil resistance, aging resistance, weather resistance, environmental protection, non-toxic, decomposable and other characteristics unmatched by other plastic materials; at the same time, it has high waterproof and moisture permeability, wi...

Problems solved by technology

However, the existing TPU film has poor high-temperature processability. At high temperature, the TPU film is prone to stickiness. In order to avoid the high-temperature stickiness of the TPU film, it is often necessary to add a large amount of slip agent, which will cause slippage in the TPU film product. The agent is easy to precipitate, and the tear strength of TPU film products is poor
