Method for manufacturing environment-friendly type geothermal heat floor

Abstract

This invention relates to a method for preparing an environment-friendly type geothermal floor, which comprises the following steps: a) preparing the base material including the regenerative material of the waste vinyon, ligno-cellulose, light calcium carbonate, acrylate polymer, geoceric acid, calcium stearate, titanium dioxide, atoleine and solid paraffin; b) spreading nontoxic binder on the base material, stitching the base material with the wood slice of the same size, between the base material and the veneer is the binder layer with nontoxic binder; c) setting corresponding tenon and beard around the base material, arranging dump discharging venting slot along the long edge direction in the bottom of the base material, and then getting the end product.

Description

technical field [0001] The invention relates to a preparation method of a floor, in particular to a preparation method of a moisture-proof and non-deformable environment-friendly geothermal floor. The finished product is especially suitable as a material for surface floor covering, wall covering and shed roof covering. Background technique [0002] At present, with the improvement of people's living standards and environmental awareness, indoor geothermal heating systems have begun to be widely used. The traditional geothermal floor is generally composed of thermal insulation layer, geothermal pipeline, concrete leveling layer, keel and floor tiles layer by layer on the structural layer of the original ground. Because the keel is set on the concrete leveling layer, expansion joints need to be set when laying floor tiles, so it affects the orderliness and appearance of the ground. In view of this situation, Chinese Patent No. 02203723.3 "composite geothermal floor" discloses...

AI Technical Summary

Problems solved by technology

It is very difficult to extrude the overly long base material resin composite board and to process and bond the overly long surface veneer board, which not only increases the manufacturing cost, takes a lot of work, wastes raw materials, but also has a low yield

In addition, due to the unreasonable structural design of the floor, the interface connection is not strong

The bottom surface is provided with 6 parallel grooves with a rectangular cross-section along the extension direction, which reduces the strength of the floor in the length direction and is easy to break

The reason is that the overlapping length of the convex and groove openings processed on both sides of the floor is short, and the number of parallel grooves at the bottom of the board is too large, so that the distance between the grooves is too narrow, the cross section of the groove is rectangular, and the groove bottom There is residual processing internal stress, resulting in a decrease in the strength of the floor, which is easy to crack and break

At the same time, the raw material organic matter used in the base resin composite board of the latter floor is waste plastic PE resin, and the proportion of inorganic filler is large, and no suitable plastic processing aids are added in the regeneration process, such as processing stability Therefore, the processing fluidity of the synthetic resin is poor, which is easy to damage its extrusion equipment and affect the extrusion efficiency, and because of the poor affinity between the inorganic filler and the organic matter after mixing, it will make the after molding The product quality does not meet the requirements of relevant standards

Affected by the above factors, the substrate not only needs to be extruded multiple times to form, but also the product is prone to photo-oxygen degradation and thermo-oxidative aging, which affects the use effect as a geothermal floor and reduces its service life
