Floor based on elastic interlayer

Abstract

The invention discloses a floor based on an elastic interlayer. The floor comprises an upper surface layer made of a hard material and a lower base layer made of hard PVC material, and the elastic interlayer is mounted between the upper surface layer and the lower base layer. The floor based on the elastic interlayer is good in crushing resistance and not easy to sunken or be damaged under effect of hard objects, and when elasticity and comfort level of the floor is improved, bearing capacity and stability of the floor can be ensured at the same time.

Description

technical field [0001] The present invention relates to hard PVC floor, especially a kind of floor based on elastic interlayer. Background technique [0002] Existing PVC flooring, such as the Chinese patent "Waterproof and Silent Composite Flooring" (CN202324521U), mainly includes an upper layer of PVC film 1, a middle core board 2 (using bamboo-plastic board or wood-plastic board) and a bottom-layer silent layer 3. The main function of the PVC film 1 on the upper layer is to be waterproof, wear-resistant and beautiful, and the function of the core board 2 is to provide a flat and hard covering surface for the PVC film 1 . This traditional PVC composite floor, because the hardness of the PVC film on the upper layer is low, it is easy to be dented or damaged when stepped on by a hard object (such as the heel of a high-heeled shoe). Do not increase the thickness and hardness of the core board to increase the support for the lower hardness PVC film, which will lose the elasti...

AI Technical Summary

Problems solved by technology

This traditional PVC composite floor, because the hardness of the PVC film on the upper layer is low, it is easy to be dented or damaged when stepped on by a hard object (such as the heel of a high-heeled shoe). Do not increase the thickness and hardness of the core board to increase the supporting force to the lower hardness PVC membrane, which loses the elasticity of the floor

[0003] Not only the above-mentioned defects exist, but the bigger problem is that the traditional processing method of the PVC film is the calendering method, that is, the PVC mixture with a certain temperature is rolled and formed by pressing rollers, which requires the PVC mixture to be rolled and formed. Add a plasticizer (such as the Chinese patent "A PVC Floor" CN105482285A) to improve the softness of the PVC mixture, so that it can be rolled

Adding a plasticizer reduces the hardness of the PVC film, and the compression resistance is poor, and it will cause depressions under the action of hard objects. Adding a plasticizer also increases the production cost of the PVC film. The odor of the plasticizer is more or less harmful to the human body. are harmful, even carcinogenic
