High-performance waterproof fireproof external thermal insulating decorative board and manufacturing process

Abstract

The invention discloses a high-performance waterproof fireproof external thermal insulating decorative board which comprises a thermal insulating layer, a finish coat and a wall covering layer, wherein two surfaces of the thermal insulating layer are respectively connected with one surface of the finish coat and one surface of the wall covering layer in surface-surface contact; the thermal insulating layer comprises a fire-proof fiber layer, fire-proof sealing layers and a fire-proof stay rope; and fire-proof sealing layers are distributed on two surfaces of the fire-proof fiber layer; the fire-proof stay rope penetrates through the fire-proof fiber layer and the fire-proof sealing layers so as to tighten the fire-proof sealing layers at two surfaces of the fire-proof fiber layer. The invention also discloses a manufacturing process of a high-performance full-flame-retardant insulation decorative board, wherein the manufacturing process comprises the following steps: tiling the fire-proof fiber layer; tiling the fire-proof sealing layers; enabling the fire-proof stay rope to penetrate through the fire-proof fiber layer and the fire-proof sealing layers so as to tighten the fire-proof sealing layers to form the thermal insulating layer; spraying mortar respectively on two surfaces of the thermal insulating layer so as to form the finish coat and the wall covering layer; drying and curing; burnishing and sanding the finish coat; spraying a coating layer; covering a protective membrane; cutting and molding; and packaging to obtain the finished product. The external thermal insulating decorative board has temperature insulating, waterproof and fire-proof performances.

Description

technical field [0001] The invention relates to an external thermal insulation decorative panel and a production process, in particular to a high-performance waterproof and fireproof external thermal insulation decorative panel and a production process, belonging to the production field of external thermal insulation decorative panels. Background technique [0002] In recent years, the country has vigorously advocated the concept of environmentally friendly and energy-saving buildings, and promoted the promotion of energy-saving buildings. Performance, so that the indoor heat (or cold) is not easy to leak to the outside, so as to achieve the purpose of energy saving and environmental protection. [0003] The defects of the existing external thermal insulation decorative boards are: 1. The decorative layer of the external thermal insulation decorative boards is an outsourced finished board (aluminum-plastic board, inorganic resin board or calcium silicate board), and iron gl...

AI Technical Summary

Problems solved by technology

[0003] The defects of the existing external thermal insulation decorative boards are: 1. The decorative layer of the external thermal insulation decorative boards is an outsourced finished board (aluminum-plastic board, inorganic resin board or calcium silicate board), and iron glue is used for compounding with the thermal insulation layer ( The combustion performance is B3 level) as a binder after cold pressing for 4-6 hours. The formed product has a large rebound stress, which is easy to cause board surface warping and glue opening (separation of the decorative layer and the insulation layer); 2. Since the insulation layer (mostly extruded polystyrene board) is a combustible material (the highest combustion performance is B1), the adhesive (iron glue) that is pasted and connected between the insulation layer and the facing layer is a combustible material (combustibility B2 level), the sealant (mostly silicone sealant) between the thermal insulation and decorative panels is a flammable material (combustibility level is B2), and the combustion performance of its products and insulation systems cannot meet the "About Further clarification on the relevant requirements for fire protection supervision and management of external thermal insulation materials for civil buildings" (Gong Xiao [2011] No. 65) "The external thermal insulation materials for civil buildings use materials with a combustion performance of Class A"

The above-mentioned patented technology has the following defects: directly bonding the non-combustible inorganic thermal insulation board to the facing layer does not reach the required bonding strength at all, and the facing layer may fall off; the non-combustible inorganic thermal Under normal circumstances, it is easy to damage itself and cause cracks and peeling off of the finish layer; during construction, it is necessary to spray mortar on the wall, and the construction is more troublesome

In summary, the above-mentioned patented technologies are basically not practicable
