Wherein the fireproof layer 1 and the pasting layer 3 are basalt fiber layers, and the insulation layer 2 is a kapok fiber layer. The thermal insulation layer 2 and the adhesive layer 3 are connected by compound acupuncture. The fireproof layer 1 and the insulation layer 2 are bonded and formed by hot rolling. By using basalt fiber and kapok fiber as raw materials, a layer of kapok fiber net is sandwiched between two layers of basalt fiber net, and the thermal insulation layer 2 and the adhesive layer 3 are compositely connected by acupuncture technology, and then the fireproof layer 1 and the thermal insulation layer are bonded by hot rolling. Layer 2 forms a composite structure, and the composite structure is connected to the wall body. The connection performance of the overall structure is stable, and the functions of heat preservation and fire prevention are realized.

The main composition of basalt fiber is silica, which is a typical silicate fiber, so it is easy to combine with the surface of the concrete wall as an adhesive layer 3, and it is not affected by the temperature change caused by the wall during use. The interface delamination phenomenon caused by different thermal expansion coefficients of the body, and at the same time, basalt fiber also has the advantages of good mechanical properties, strong heat resistance, acid and alkali resistance, low hygroscopicity, green and pollution-free, etc. The disadvantage of high coefficient has good fire performance. Kapok is a kind of natural wild cellulose fiber, which has the characteristics of high hollowness, light weight and warmth retention.

The thermal insulation layer 2 is made of kapok fiber non-woven fabric, which has a good thermal insulation effect. The adhesive layer 3 is made of basalt short fiber needle-punched non-woven fabric. This kind of structure has a loose surface structure and large pores, so it also has a good heat insulation function. complex. The thickness of each layer of the composite structure can be selected according to the heat preservation requirements of the environmental conditions in the area of use. The preferred fireproof layer 1 is a layer structure with a thickness of 3mm to 7mm to achieve a good fireproof effect; the thickness of the adhesive layer 3 is not less than The layer structure of 2mm ensures a stable connection with the wall body; the insulation layer 2 is a layer structure with a thickness of 2mm to 6mm, which can obtain better insulation effect.
