Problems solved by technology

Therefore, the above-mentioned organic thermal insulation materials used in the past will not be able to continue to be used, the production equipment will also be eliminated, and the construction of the civil construction market will also face a stagnation.
[0003] Due to the restrictions of the No. 65 document, most of the A-level external wall insulation board materials used in architectural design at present are rock wool board and foam glass. Common quality problems such as low water absorption, cracking, leakage or even falling off are difficult to solve, and it is difficult to survive the same life as the building. The dis

Embodiment Construction

[0011] As shown in Figure 1 is the comparative figure of composite thermal insulation board of the present invention and existing thermal insulation board, and among Fig. 1, 1 is organic thermal insulation material, and 2 is the fireproof material as protective isolation layer, and 3 is exterior wall covering mortar. From the side sectional view and plan sectional view, it can be seen that the new material has an additional protective barrier than the old material. From the construction renderings, it can be seen that the organic insulation materials of the old material are connected into a large piece, while the new material has one by one. The fireproof layer 2 is disconnected to form fireproof units one by one. If the outer wall covering mortar 3 falls off, the old material will be exposed to the organic thermal insulation material 1, and will catch fire when encountering an open flame. Even if the outer wall covering mortar of the new material falls off, the organic thermal...

Abstract

The invention discloses a composite heat insulating material, which comprises an organic heat insulating material and a fireproof material on the surface of the organic heat insulating material, wherein the organic heat insulating material is selected from a polyphenyl plate, an extrusion molding plate and a polyether-urethane plate; the fireproof material is selected from one or more than one of cement mortar, rock mortar, coal ash and fireproofing agent; the fireproof material is compounded on the surface of the organic heat insulating material in a mode of spraying, coating, brushing or dipping and the like and is used for insulating heat for the wall body of a building, and the fireproof material can reach the A-level fireproof standard; the problem that the traditional building heat insulating material is in shortage can be solved, and the organic heat insulating material which is about to exit the heat insulating market gets a new life; production cost can be saved greatly, great social benefit is brought, and the dual standards of saving energy and preventing fire can be achieved.

Description

technical field [0001] The invention relates to a composite thermal insulation material, in particular to a composite thermal insulation board. Background technique [0002] At present, most of the organic thermal insulation materials for the walls of civil buildings in my country are polystyrene boards, extruded plastic boards, polyurethane boards, etc., because of their superior thermal insulation performance, good waterproof performance and impact resistance, they can effectively solve the wall cracks It is widely used in external wall insulation and is currently an ideal energy-saving and emission-reducing material. However, the biggest disadvantage of this type of material is its poor fire performance, so it is very easy to cause fire hazards during transportation, construction, and use after completion of the project. According to the requirements of the Ministry of Public Security Fire Bureau (2011) No. 65 notice, from March 15, 2011, the external wall insulation of c...
