Mixed material containing graphite geothermal cushion and production technique thereof

Abstract

The invention discloses a graphite-containing geothermal cushion layer mixing material and production technology thereof. The mixing material is prepared by the following steps: graphite powder, sepiolite cashmere, lime putty, water-proofing powder, fine sand, water, an auxiliary agent and so on are evenly mixed into slurry according to the mixture ratio, and the needed blank is prepared and is naturally air-dried or dried and maintained; and the graphite powder, the sepiolite cashmere, the water-proofing powder, and the auxiliary agent can also be directly and evenly mixed according to the mixture ratio and are directly used for construction. In the material, the graphite powder has transverse heat conduction function, and the sepiolite cashmere can perform thermal insulation, make the heat radiated in a balanced mode, is more durable, prevents cracks and increases the toughness, so as to ensure that a floor is evenly heated, prolong the average life of the floor, and also improve the effect of geothermal heating. The material has the advantages of good heat conduction and thermal insulation effect, simple production technology, and convenient operation, and can be widely applied to the field of geothermal heating.

Description

technical field [0001] The mixed material of the invention relates to an indoor geothermal cushion building material, in particular to a novel indoor heat conduction and thermal insulation geothermal cushion material containing graphite material. Background technique [0002] In recent years, geothermal heating has been widely used as an indoor heating method, and geothermal heating facilities generally refer to setting a heat insulation layer on the ground, laying floor heating pipes on the heat insulation layer, and covering the pipes with insulation materials to form an insulation layer (storage thermal layer / cushion layer), and lay a leveling layer and a ground layer on top of the thermal insulation layer. There is a heat medium flowing through the floor heating pipes, and the heat will be transferred to the insulation layer, and the insulation layer will accumulate the heat and slowly transfer it upwards through the leveling layer to the ground floor, making the floor o...

Problems solved by technology

Due to the high density of cement mud, the heat transfer of geothermal cushion materials is slow, not heat-resistant, and it is easy to dry and crack, which affects the heating effect; while organic foam materials such as polystyrene have poor temperature resistance, and the lateral thermal conductivity is almost zero, resulting in poor heating of the floor. Average, which also affects the average life of the floor
