Elastic sound-absorbing PVC (Polyvinyl Chloride) floor and preparation method thereof

Abstract

The invention belongs to the field of PVC (Polyvinyl Chloride) floors and relates to an elastic sound-absorbing floor. The elastic sound-absorbing PVC floor comprises an elastic PVC transparent layer, a printing fabric layer, a base material layer and an elastic sound-absorbing layer which are arranged in sequence from top to bottom. The elastic sound-absorbing PVC floor has the advantages that due to use of highly-polymerized PVC, the transparent layer has elasticity and is comfortable in foot feel and low in noise; the base material layer has an effect of stabilizing the physical properties of the floor; the elastic sound-absorbing layer has a structure with convex and concave patterns, the part with the convex patterns has high elasticity and can generate elastic deformation when the floor is stepped, and the part with the concave patterns and the ground form a cavity so as to realize the effects of reducing sound generation and absorbing sound; and the elastic sound-absorbing layer and the other layers are laminated together by one time of heat lamination, so that the elastic sound-absorbing floor does not contain glue, VOC (Volatile Organic Compound) and formaldehyde, and is more environment-friendly.

Description

technical field [0001] The invention belongs to the field of PVC flooring, and in particular relates to a sound-absorbing floor and a preparation method thereof. Background technique [0002] At present, the PVC lock floor on the market is all hard PVC floor, which does not have elasticity, so the foot feels not comfortable enough. When walking on high heels, it is easy to generate noise, and the sound insulation effect is not good. [0003] To this end, the industry has developed related floors (WPC, SPC) that use glue to attach foamed film layers (foamed EVA, foamed IXPE, foamed rubber) to improve foot feel and sound insulation; or develop overall soft floors to improve Foot feel, sound insulation effect, but glue is required for paving. [0004] CN 103114706 discloses a resilient floor. A foam layer is provided between the surface layer and the bottom layer. The foam layer is coated with a film-forming agent and cold-pressed again to connect the upper layer and the botto...

AI Technical Summary

Problems solved by technology

[0007] The above-mentioned foam film floor lock floor has a complicated production process and needs to use glue to fit the foam film layer, which contains volatile substances (VOC) and is not environmentally friendly

The above-mentioned elastic floor not only needs to use adhesives in the production process, but also needs to use adhesives in the paving process. The process is complicated and the paving is complicated.
