Description

A composite building material board

technical field

The utility model specifically relates to a composite building material board, which belongs to the technical field of building materials.

Background technique

Building energy conservation is a sustainable development strategy and a strategy of rejuvenating the country through science and education vigorously advocated by the Chinese government in recent years, and it is an important national policy that contributes to energy conservation and environmental protection. Therefore, vigorously developing energy-saving buildings has become a consensus. In 1986, my country promulgated the first "Civil Building Energy Conservation Design Standard" for trial implementation, and then formulated different building energy conservation design standards according to my country's national conditions to meet the national building energy conservation requirement of 65%. In order to achieve the above building energy-saving requirements, the role of building thermal insulation materials in building energy conservation has become increasingly prominent. The existing building thermal insulation materials in my country mainly include the following categories: the first category is glass wool, rock wool, etc. These materials have disadvantages such as heavy weight, complicated construction, serious environmental pollution, and damage to the health of construction workers; The second category is polystyrene foam, polyvinyl chloride foam polyurethane foam and other foam products. These materials generally have disadvantages such as poor fire resistance, low combustion oxygen index, and high smoke density; the third category is represented by phenolic foam. New fireproof materials have disadvantages such as low tensile strength, easy slag drop, powder removal, poor surface bonding strength, easy deformation, high brittleness, easy fracture during construction, difficult construction, and poor dimensional stability.

The technical problem to be solved by the utility model overcomes the existing defects, and provides a composite building material board, which not only has the functions of fire prevention, sound insulation and heat preservation, but also has a relatively It is solid, prevents environmental pollution, ensures the health of construction workers, improves stability, and can effectively solve the problems in the background technology.

In order to solve the above technical problems, the utility model provides the following technical solutions:

The utility model provides a composite building material board, which comprises a material board body. The middle part of the material board body is provided with a thermal insulation layer. Both sides of the thermal insulation layer are sequentially provided with a decorative layer, a fireproof layer, a reinforcement layer and The sound-absorbing layers are bonded to each other by waterproof glue.

As a preferred technical solution of the utility model, the sound-absorbing layer is a honeycomb core board.

As a preferred technical solution of the present invention, the honeycomb core plate is in the shape of a long plate and has several honeycomb-shaped through holes on it.

As a preferred technical solution of the utility model, the reinforcement layer is integrally formed by several reinforcement ribs, and the reinforcement ribs are made of PVC material.

As a preferred technical solution of the present invention, the material plate body is made of wood material.

As a preferred technical solution of the present invention, the fireproof layer is a flame retardant paint layer.

detailed description

The preferred embodiments of the present utility model are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present utility model, and are not intended to limit the present utility model.

Embodiment: Please refer to Fig. 1, a composite building material board of the present invention, comprising a material board body 1, the middle part of the material board body 1 is provided with an insulation layer 6, and the two sides of the insulation layer 6 are arranged in sequence from the inside to the outside. A decorative layer 2, a fireproof layer 3, a reinforcing layer 4 and a sound-absorbing layer 5 are provided and bonded to each other by waterproof glue. The sound-absorbing layer 5 is a honeycomb core board, and the honeycomb core board is long plate-shaped and on There are several honeycomb-shaped through holes, which have the function of sound attenuation. The reinforcement layer 4 is integrally formed by several reinforcement ribs, and the reinforcement ribs are made of PVC material, which has a strong structure. The material board body 1 is made of wooden materials. As a result, the fire-proof layer 3 is a flame-retardant paint layer, which can play a flame-retardant role, and the heat-insulating layer 6 is made of polyethylene material, which has a better heat-insulating effect.

It should be noted that the utility model is a composite building material board. When working, by setting a fireproof layer, a reinforcing layer, a sound-absorbing layer and a heat-insulating layer, it not only has the functions of fire prevention, sound insulation and heat preservation, but also has a relatively strong structure, and It prevents environmental pollution, ensures the health of construction workers, and improves stability.

Finally, it should be noted that: the above is only a preferred embodiment of the utility model, and is not intended to limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art , it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
