Building interior wall heat retaining board and manufacturing method thereof

Abstract

The invention discloses a building interior wall heat retaining board and a manufacturing method thereof. The interior wall heat retaining board is low in cost and environmentally friendly. The building interior wall heat retaining board is characterized in that the building interior wall heat retaining board is composed of cement fixing layers, a coconut tree brown layer, steel wire meshes, diatomite and a plurality of communicating holes, wherein the coconut tree brown layer is in the middle, the steel wire meshes are arranged on and under the coconut tree brown layer correspondingly, the multiple communicating holes are evenly formed in the coconut tree brown, the cement fixing layers are poured on the outer sides of the two steel wire meshes, and the cement fixing layers on the two sides are connected with cement columns by penetrating through communicating holes. The outer side of each of the cement fixing layers is coated with a layer of the diatomite, the thickness of the coconut tree brown layer is one third of the thickness of the whole heat retaining board, the middle of the coconut tree brown is compact, the two sides of the coconut tree brown are floppy, and the floppy position of the coconut tree brown and the cement fixing layers are inlaid into each other. The interior wall heat retaining board prepared by adopting the method is environmentally friendly and harmless, low in manufacturing cost and easy to popularize.

Description

technical field [0001] The invention relates to a building interior wall insulation board and a manufacturing method thereof, relating to a low-carbon and environment-friendly building interior wall insulation board and a manufacturing method thereof, belonging to the field of construction equipment. It particularly relates to a low-cost, environment-friendly interior wall insulation board and a manufacturing method thereof. Background technique [0002] At present, insulation boards are usually made of polystyrene resin or polyurethane as raw materials plus other raw and auxiliary materials and polymers, mixed with heat and injected with a catalyst, reacted, and then extruded to form a rigid foam plastic board. , with moisture-proof and water-proof performance, but this kind of insulation board itself is the product of chemical reaction. The chemical reaction process has chemical pollution. The raw material of the insulation board is not environmentally friendly and low-car...

AI Technical Summary

Problems solved by technology

The edge of the finish layer of the low heat capacity interior wall insulation board is bent toward the side of the insulation layer, and the bent part of the edge of the finish layer covers part of the edge of the insulation layer; the finish layer and the insulation layer are parallel to the interior wall The size of the facing layer is smaller than the size of the insulation layer. When paving, the adjacent insulation layers are connected to each other to block the thermal bridge, and a structural seam is formed between the adjacent facing layers. The polyurethane insulation material in this scheme is made of Combination of polyols, foaming agents, isocyanates and other additives, obtained through a foaming reaction, is essentially a chemical reaction, there is chemical reaction pollution, and its moisture resistance in a humid environment is poor

[0004] Publication No. CN106759999A discloses a thermal insulation board for an interior wall, comprising a base layer, a thermal insulation layer, a sound insulation layer, an air purification layer, and a decorative antibacterial layer arranged sequentially from the inside to the outside; the base layer, the thermal insulation layer, the sound insulation layer, the The above-mentioned air purification layer and antibacterial layer are connected in sequence; a large number of composite materials are used, and the silver-based composite nanomaterials on the surface, the toxicity of nano-silver is stronger than that of large-scale silver, and it is more harmful to the human body. The wall insulation board can be sterilized, but it is more harmful to the human body, affects the living environment, endangers human health, and is not environmentally friendly
