Fire-proof type exterior wall composite thermal insulation decorative board and manufacture method thereof

Abstract

The invention belongs to the technical field of building materials and particularly relates to a fireproof composite thermal-insulation decorative board for an exterior wall and a preparation method thereof. The fireproof composite thermal-insulation decorative board for the exterior wall is characterized in that the fireproof composite thermal-insulation decorative board for the exterior wall comprises a fireproof thermal insulation layer, a strengthening layer and a decoration layer. The thickness of the fireproof thermal insulation layer is between 30 and 80mm, and the fireproof thermal insulation layer consists of rock wool and a calcium silicate board, or mineral cotton and the calcium silicate board, or a rock wool board and the calcium silicate board, or a mineral cotton board and the calcium silicate board, or one of the mineral cotton board and the rock wool board, wherein the rock wool, the mineral cotton, the rock wool board, and the mineral cotton board are all subjected to hydrophobic treatment by organic silicon. The thickness of the strengthening layer is between 3 and 8mm, and the strengthening layer is polymer mortar or the calcium silicate board. The decoration layer is fluorobcarbon coating, metallic paint, stone like coating or crylic acid emulsion paint. The thermal insulation board is arranged on the wall surface through a mode with the combination of adhesion and anchorage. The invention can prevent the thermal-insulation decorative board for the exterior wall from being burnt and destroyed too early during fire hazards, protect the safety of personal life of personnel and properties in buildings during the fire hazards, and has the advantages of controllable quality of prefabricated forming, assembled construction, and integrated decoration and thermal insulation functions.

Description

1. Technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a fireproof exterior wall composite thermal insulation decorative board and a preparation method thereof. 2. Background technology [0002] At present, building energy consumption has been ranked alongside industrial energy consumption and transportation energy consumption, and has become the three "big energy consumers" in my country's energy consumption. In particular, building energy consumption has shown a sharp upward trend along with the continuous increase in the total number of buildings and the improvement of living comfort. In 2005, Qiu Baoxing, the former vice minister of the Ministry of Construction, pointed out that the construction area of ​​new urban and rural buildings in my country is nearly 2 billion square meters each year, of which more than 80% are high-energy-consuming buildings; the existing buildings are nearly 40 billion square m...

AI Technical Summary

Problems solved by technology

[0005] 1. The existing external wall thermal insulation system adopts on-site manual construction, which is difficult to ensure the thermal insulation effect of the external wall thermal insulation system, and it is difficult to control the cracking of the external wall thermal insulation system;

[0006] 2. The existing external wall insulation system adopts on-site manual construction, which requires a long construction period and slow construction speed;

[0007] 3. Existing external wall thermal insulation products seldom consider that the organic thermal insulation material of the thermal insulation layer burns in case of fire, which will cause the failure of the entire external thermal insulation system of the external wall and eventually endanger personal life and property safety.

The Chinese Patent No. CN 200610053884.2 discloses a thermal insulation board and its manufacturing method. The thermal insulation board includes a cement wear-resistant layer, a reinforcement layer and an organic foam board, but the thermal insulation board does not consider the damage to the organic foam in the event of a fire. Protection of boards without decorative treatment of the board surface

[0009] To sum up, the above-mentioned patent specification does not consider the use of a fireproof exterior wall composite thermal insulation decorative board including a fireproof insulation layer, a reinforcement layer and a decorative layer and its preparation method
