Ground heating floor made of polymer alloy materials and preparation method thereof

Abstract

The invention discloses a ground heating floor made of polymer alloy materials and a preparation method thereof. The ground heating floor is structurally characterized in that the ground heating floor is of a three-layer composite structure, and specifically, a bottommost layer, i.e. a base layer, is a PVC (Polyvinyl Chloride)-based polymer alloy composite material layer; a middle layer is a co-extrusion composite decorative layer, and knurling treatment is performed on the surface of the middle layer; a co-extrusion process is adopted to the base layer and the middle layer, so as to form an integral structure once; a topmost layer is a UV (Ultraviolet)-treated transparent antibacterial wear-resisting layer. The preparation method comprises the following steps of (1) mixture and preparation of the base layer; (2) online co-extrusion lamination of the middle layer and the base layer; (3) online knurling treatment of the surface of the middle layer; (4) surface UV antibacterial wear-resisting treatment. The forming preparation process disclosed by the invention has the advantages of simple process and environmental friendliness; the floor has the advantages of high heat conductivity coefficient, high strength, heat resistance, flame retardance and no formaldehyde emission and has an antibacterial wear-resisting effect on the surface; the ground heating floor prepared by using the technique has good ground heating conductivity, dimensional stability, anti-fouling environmental friendliness and use durability.

Description

technical field [0001] The invention belongs to the field of building decoration materials, and in particular relates to a floor heating floor made of polymer alloy material and a preparation method thereof. Background technique [0002] At present, the floors traditionally selected as floor heating systems are mostly composite floors, such as composite PVC floors, solid wood composite floors, laminated floor-grade bamboo and wood floors, etc. Composite flooring is composed of multiple layers with different functions pressed and compounded by bonding technology. The preparation process is complicated, and there are disadvantages such as high energy consumption and environmental pollution; During the process, it is easy to release a certain amount of formaldehyde by heat, which is harmful to human health; during the long-term use of traditional geothermal flooring, mold will be formed on the floor surface due to dust and dirt, which will affect human health; traditional geo...

Composite flooring is composed of multiple layers with different functions pressed and compounded by bonding technology. The preparation process is complicated, and there are disadvantages such as high energy consumption and environmental pollution; During the process, it is easy to release a certain amount of formaldehyde by heat, which is harmful to human health; during the long-term use of traditional geothermal flooring, mold will be formed on the floor surface due to dust and dirt, which will affect human health; traditional geothermal flooring, such as The long-term use of composite PVC floor will cause warping and deformation due to long-term heating use; the thermal conductivity of composite floors such as wooden floor and bamboo floor is relatively low, between 0.17-0.34w / (m*k), and the relative energy consumption is relatively long-term use; The traditional geothermal floor does not have the characteristics of fire and flame retardancy, it is easy to catch fire, and there is a safety hazard; the surface of the traditional geothermal floor has the worst wear resistance, and it is easy to form scratches after long-term use, which will affect the appearance of the floor surface
