A kind of decorative bamboo plastic geothermal floor and its cold pressing processing method

Abstract

The invention provides a facing bamboo-plastic heating floor and a cold-pressing processing method thereof. The facing bamboo-plastic heating floor is formed by combining a bamboo-plastic floor base material layer, a glass fiber cloth layer and a heavy bamboo veneer layer. The bamboo-plastic floor base material layer comprises, by mass, 20%-25% of polyvinyl chloride (PVC) and polyether block amide blends, 6%-8% of nanoscale bamboo charcoal powder, 25%-30% of chinastone powder, 7%-9% of lubricating agents, 2%-3% of coupling agents and the balance bamboo powder. A manufacturing method of the facing bamboo-plastic heating floor comprises the steps that firstly, bamboo materials are pulverized and mixed with the chinastone powder at a high temperature after being subjected to fluoridation, then other components are placed into a high-speed mixing and dispersing machine jointly and mixed for 20 minutes after the temperature is increased to 125-130 DEG C, afterwards the temperature is decreased to 45 DEG C through cooling, and finally, the mixture is extruded through an extruding machine, so that a bamboo-plastic floor base material is obtained; and then the bamboo-plastic floor base material, the glass fiber cloth and the heavy bamboo veneer are assembled and combined after being coated with adhesives, and the facing bamboo-plastic heating floor is obtained through the procedures such as cold pressing. The floor has the natural material texture, high heat-conducting efficiency, low thermal expansivity and good mechanical performance, is not prone to buckling deformation and can be widely used in the heating floor field.

Description

technical field [0001] The invention relates to a bamboo-plastic composite material, in particular to a method for manufacturing a veneered bamboo-plastic geothermal floor. Background technique [0002] The traditional bamboo-plastic composite floor is a profile made by mixing bamboo powder, thermoplastics and related additives in a certain proportion, granulating, and melt-extruding. Due to its advantages of strong mechanics, good dimensional stability, moisture resistance, corrosion resistance, and aging resistance, it has been widely used in outdoor floors, plank roads and other related fields. Indoor use of bamboo-plastic composite flooring is often not accepted by people due to lack of natural surface texture, poor foot feel, and installation problems. [0003] In recent years, with the improvement of people's living standards, geothermal wood flooring has gradually become popular. However, it is very rare to directly use bamboo-plastic composite materials in wooden g...

AI Technical Summary

Problems solved by technology

The bamboo-plastic flooring currently on the market is usually made of bamboo fibers and thermoplastics with related additives, melt blended and extruded, and there are poor coupling agents at the interface between bamboo fibers and thermoplastics, low thermal conductivity, and thermal expansion coefficient. High, easy to warp and other problems, it can only be used as an ordinary floor, and cannot meet the growing needs of geothermal floor
