Description

A new type of fireproof insulation board

technical field

The utility model relates to a novel fireproof heat preservation board, which belongs to the field of building material heat preservation boards.

Background technique

Now with the development of construction economy, it is more and more important to improve the fireproof and thermal insulation effect of buildings. Generally, the fireproof and thermal insulation layer is fixed on the outer wall of the building itself, and the outer wall of the existing building is added with a layer of fireproof Insulation board. Early exterior wall insulation materials were mainly mortar. In recent years, there are many types of insulation materials used in exterior wall insulation technology, such as molded polystyrene board, polyurethane foam, extruded polystyrene foam, etc. These materials have poor heat resistance, poor aging resistance, low insulation board strength, easy to burn and release a lot of toxic fumes when burned.

Contents of the invention

(1) Technical problems to be solved

In order to solve the above problems, the utility model proposes a simple and reasonable structure, easy to use, high aging resistance, high strength fire-proof insulation board, firmly bonded with the building wall, stronger fire resistance, non-toxic and smoke-free, heat preservation Sound insulation, more environmentally friendly and energy-saving fireproof insulation board.

(2) Technical solutions

A new type of fireproof insulation board according to the utility model is characterized in that it comprises a three-layer structure composed of a fireproof layer, an intermediate layer and an insulating layer, one side of the middle layer is bonded to the fireproof layer of the surface layer, and the other side is bonded to the fireproof layer of the surface layer. Insulation bonding.

Further, according to claim 1, a new type of fireproof insulation board is characterized in that: the middle layer is made of graphite polystyrene board, glass fiber, carbon fiber, rock wool, etc., and there is a reserved holes.

Further, the fireproof layer is composed of 5 to 11 parts of magnesium oxide; 1 to 6 parts of diatomaceous earth; 0.4 to 1.1 parts of magnesium sulfate; 0.2 to 0.3 parts of urea aldehyde milk fat; modified polystyrene and Composed of 2 to 8 parts of flame retardant particles.

Further, the insulation layer can be composed of polyurethane insulation board, polystyrene insulation board, extruded insulation board, modified polystyrene insulation board, phenolic insulation board, etc.

Further, the bonding surface of the thermal insulation layer is provided with a bonding rough surface which facilitates bonding with the building wall.

(3) Beneficial effects

Compared with the prior art, the utility model has the following beneficial effects: the utility model is simple and reasonable in structure, easy to use, high in aging resistance, high in strength of the fireproof insulation board, firmly bonded with the building wall, and stronger in fire resistance , non-toxic and smoke-free, thermal insulation and sound insulation, more environmentally friendly and energy-saving; especially the use of non-toxic, non-corrosive, non-moisture-absorbing, non-caking diatomite, which greatly reduces the production cost and meets the requirements of economy and environmental protection , very popular.
