technical field

The utility model relates to a reinforced waterproof board, which belongs to the field of heat preservation and energy saving of building exterior walls, in particular to a reinforced waterproof rock wool board.

Background technique

The traditional form of building wall insulation is mainly polystyrene board or polyurethane foam board, and anti-cracking mortar, exterior wall putty and finishing layer are applied on the surface of polystyrene board. However, due to the flammability of polystyrene materials, this kind of insulation board is very easy to cause fire. Although it can be modified to reach Class B, it cannot reach Class A non-combustibility, and fire hazards still exist. It poses a great threat to people's life and property.

The rock wool board is made of basalt and other natural ores as the main raw materials. The rock wool board is melted into fibers at high temperature, added with an appropriate amount of binder, and solidified. It has been widely used in the field of construction at home and abroad for its excellent thermal insulation and fire resistance performance, but due to its own structure, its compressive and tensile strength is poor, and its geometric dimensions are unstable due to the influence of the external environment, so it is difficult to make sandwich structural panels; Moreover, the rock wool board itself is very easy to absorb water and be affected by moisture. Even after hydrophobic treatment, the moisture-proof performance is not ideal.

There are no less than 7 special connectors for the enhanced waterproof rock wool board per square meter.

The special connecting piece is composed of a plastic sleeve with a disc at the end, a plastic gasket and a screw that are adapted to the hole diameter of the plastic sleeve, and the plastic sleeve penetrates the core layer of the rock wool board. And through the plastic gasket and screw threaded connection.

There is a space between the top of the metal bolt and the plastic sleeve. It can effectively solve the defect of thermal bridge effect.

In the above technical scheme, the hydrophobic rock wool board is used as the core material. In order to have better mechanical strength, the rock wool board with a bulk density between 100 and 200kg/ ^m3 is selected; The upper surface and the lower surface of the rock wool board are strengthened respectively to enhance the compressive strength, tensile strength and shear strength of the rock wool board, so that the rock wool board is not easily deformed and damaged by external forces; then the board is sprayed with glue, spraying a Acrylic acid polymer can effectively reduce the stimulation of rock wool fiber to human skin, improve the waterproof and moisture-absorbing performance of the core layer of rock wool board, and can be used as an interface agent to effectively strengthen the polymer mortar and the utility model during construction. bond tensile strength.

The beneficial effects of adopting the above technical solution are: it not only ensures the thermal insulation performance of the building wall, but also solves the fire hazard; the design of the galvanized steel wire mesh increases the self-strength of the rock wool board and the bonding with the polymer mortar Tensile strength; the glue spraying process solves the defects that the rock wool board is easy to absorb moisture and has poor water resistance; the utility model has a reasonable structure and meets the requirements of mechanical design; the life of the insulation layer is prolonged, and the insulation layer has the same life as the building.
