Functional co-extrusion composite alloy material floor-heating floor and manufacturing method thereof

Abstract

The invention discloses a functional co-extrusion composite alloy material floor-heating floor and a manufacturing method thereof. The floor is of a five-layer composite structure, a board vacuum coating reflection layer is arranged on the bottommost layer, a heating layer which is the conductive heating plastic layer is arranged above the reflection layer, a PVC-based polymer alloy composite material layer is arranged above the heating layer, and a co-extrusion composite decorative layer is arranged above the PVC-based polymer alloy composite material layer. The heating layer, the PVC-based polymer alloy composite material layer and the co-extrusion composite decorative layer integrally form the whole structure through the co-extrusion technology, and a transparent layer protective layer processed through UV anti-microbial wear-resistance processing is arranged on the topmost layer. The manufacturing method of the functional co-extrusion composite alloy material floor-heating floor comprises the following steps of (1) mixture and manufacturing of the PVC-based polymer alloy composite material layer, (2) on-line co-extrusion composite of the heating layer, the co-extrusion composite decorative layer and the PVC-based polymer alloy composite material layer, (3) surface one-line knurling processing of the co-extrusion composite decorative layer, (4) vacuum coating conducted on the surface of boards and (5) surface layer UV anti-microbial wear-resistance processing. The manufacturing method of the functional co-extrusion composite alloy material floor-heating floor is simple in process, and the functional co-extrusion composite alloy material floor-heating floor manufactured by the method has the good floor heating conductivity, good size stability, anti-fouling environmental protection performance and using durability.

Description

technical field [0001] The invention relates to the field of building decoration materials, in particular to a floor heating floor made of functional co-extruded composite 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; tr...

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
