AI Technical Summary
Technical Problem
Existing PVC flooring is too hard underfoot when used in places like stadiums, causing user fatigue. It also requires the addition of sound-absorbing pads to improve the feel, increasing the process and cost.
Method used
The flooring features a double-layer LVT structure, with an upper LVT structure and a lower LVT foam structure. Through specific material ratios and production processes, including high-speed mixing, low-speed mixing, twin-screw extrusion, coating, and die-cutting, a surface layer with a certain rigidity and an inner layer with elasticity are formed.
Benefits of technology
It improves the feel of the floor underfoot, reduces processes and costs, and also has a certain cushioning performance, making it suitable for sports venues and reducing sports injuries.

Abstract
The present invention relates to the technical field of floorings. Disclosed are a dual-layer LVT soft foam flooring and a production process. The dual-layer LVT soft foam flooring comprises an LVT dual-layer structure, wherein the LVT dual-layer structure is composed of an upper-layer LVT structure and a lower-layer LVT foam structure; the upper-layer LVT structure is made of polyvinyl chloride resin, dioctyl terephthalate, calcium carbonate, an external lubricant, an internal lubricant, and a heat stabilizer; and the lower-layer LVT foam structure is made of polyvinyl chloride resin, dioctyl terephthalate, calcium carbonate, an LVT regrind material, a foaming agent, a foaming regulator, an external lubricant, and an internal lubricant. By means of extrusion foaming, the flooring contains the LVT dual-layer structure composed of LVT at the upper layer and LVT foam at the lower layer, thereby ensuring the feel of feet and also achieving the hardness of the upper layer.
