Problems solved by technology

[0002] Most of the traditional plastic composite floors use polyvinyl chloride (PVC) as the base material. The existing PVC floor has the characteristics of excellent performance and good decorative effect, but its disadvantage is that it will produce a lot of irritation when it is caught on fire or incinerated. The smell of hydrogen chloride (HCl) and the production of carcinogens such as dioxin are harmful to the environment and human body
During the processing of PVC materials, a large amount of plasticizers, stabilizers, etc. will be added. During use, these small molecular substances may migrate or precipitate, which is potentially harmful to the human body. In addition, the dimensional stability of PVC flooring is poor. , the floor material is difficult to degrade, easy to form white pollution
Compared with traditional PVC flooring, polypropylene flooring has the characteristics of environmental protection, light weight, and easy installation. However, most of the existing polypropylene flooring is made of polymers mixed with additives and then extruded, calendered or co-extruded. After molding, the products are prone to warping, high and low temperature resistance and poor weather resistance.

Abstract

The invention belongs to the technical field of polymer materials. A multi-layer structure polypropylene floor, which is composed of UV layer, first PP treatment agent layer, PP transparent layer, second PP treatment agent layer, PP printing film layer, substrate layer, IXPE glue layer and IXPE layer. The composite method includes hot pressing and bonding or extrusion online bonding; the total thickness of the polypropylene floor is 3-10mm, the UV layer is the surface layer, the first PP treatment agent layer and the second PP treatment agent The composition of the layer includes chlorinated polypropylene and organic solvents. The floor of the invention has good flatness and dimensional stability, high mechanical strength, high temperature resistance, shrinkage and warping resistance.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polypropylene floor with a multilayer structure. Background technique [0002] Most of the traditional plastic composite floors use polyvinyl chloride (PVC) as the base material. The existing PVC floor has the characteristics of excellent performance and good decorative effect, but its disadvantage is that it will produce a lot of irritation when it is caught on fire or incinerated. Hydrogen chloride (HCl), which has a strong odor, produces carcinogens such as dioxin at the same time, which is harmful to the environment and human body. During the processing of PVC materials, a large amount of plasticizers, stabilizers, etc. will be added. During use, these small molecular substances may migrate or precipitate, which is potentially harmful to the human body. In addition, the dimensional stability of PVC flooring is poor. , The floor material is difficult t...
