The application provides a prefabricated composite thermal insulation and fireproof board, which includes an insulation layer 1 arranged sequentially from the inside to the outside, and an insulation and fireproof layer 2 made of rock wool;

The outer long and wide surface of the thermal insulation layer 1 is bonded to the inner long and wide surface of the thermal insulation and fireproof layer 2;

The insulation layer 1 is an EPS insulation board, XPS insulation board, polyurethane rigid foam insulation board or graphite extruded polystyrene foam board;

The above-mentioned prefabricated composite thermal insulation and fireproof board is preferably arranged on the outer wall surface of the base-level wall through the joint action of the adhesive connection of the adhesive mortar and the anchor connection of the penetrating plate anchor nail 5 .

In one embodiment of the present application, the thermal insulation and fireproof layer 2 made of rock wool is horizontal or vertical fiber rock wool.

In one embodiment of the present application, the thickness of the thermal insulation and fireproof layer 2 is 3cm-5cm.

In the prior art, rock wool is relatively soft, and its hardness and strength (including the tensile strength and compressive strength perpendicular to the board surface) are very low. For example: the tensile strength of rock wool perpendicular to the board surface (hereinafter referred to as tensile strength) Strength) is very small. When the density of rock wool is 200Kg/ ^m3 , its tensile strength is only about 19KPa. Among organic insulation materials, the tensile strength of EPS insulation board and PF board is relatively small, but both have exceeded The tensile strength of XPS insulation board and PUR insulation board has obvious advantages, both of which are above 0.25MPa. At present, the prefabricated composite thermal insulation boards used in the external wall thermal insulation system not only have the thermal insulation performance meeting the standard requirements but also have A-level fire resistance, and because rock wool has A-level fire resistance, many industry technicians are working on rock wool boards. The inner panel is compounded with other organic insulation boards to form a composite insulation board. In the external insulation system of the thin plastered outer wall, a thin plaster surface layer and a decorative layer need to be set on the outside of the composite insulation board. The rock wool is so small The hardness and strength of the thin plastered external wall insulation system made of it make the core soft and hard and heavy on both sides. Rock wool acts as the only supporting bridge to support and connect the organic insulation board and the thin plastered surface layer. With all the weight of the facing layer, the burden borne by the rock wool is too heavy, and the soft rock wool board at the core cannot hang the organic insulation board, the thin plastering surface layer and the facing layer compounded on it, resulting in thin plastering The overall external wall thermal insulation system is relatively loose and loose, and the overall rigidity is poor, which leads to the rock wool board in the thin plaster external thermal insulation system of the external wall after the installation is completed in the later stage. The external insulation system of the gray exterior wall is invalid, and falling off from high altitude may easily cause safety accidents. For this reason, in one embodiment of the present application, when the thermal insulation layer 1 is a rigid polyurethane foam thermal insulation board, the prefabricated composite thermal insulation fireproof board includes an inner glass fiber coil, a rigid polyurethane foam thermal insulation layer arranged in sequence from the inside to the outside. , Insulation and fireproof layer made of rock wool 2. Outer glass fiber coil;

The outer long and wide surface of the inner glass fiber coil and the inner long and wide surface of the polyurethane rigid foam insulation layer form a self-adhesive connection during the polyurethane foam molding process;

The outer length and width surface of the polyurethane rigid foam insulation layer and the inner length and width surface of the heat insulation and fireproof layer 2 form a self-adhesive connection during the polyurethane foam molding process;

The outer long and wide surface of the thermal insulation and fireproof layer 2 is bonded to the inner long and wide surface of the outer glass fiber coil;

Several horizontal through-holes are arranged on the heat-preservation and fireproof layer 2, and the openings at both ends of the horizontal through-holes are flaring structures;

The horizontal through-holes on the heat-preserving and fireproof layer 2 constitute the mold cavity for polyurethane foam molding so that the rigid polyurethane foam molded in the horizontal through-holes after the polyurethane foam molding is completed The rigid foam insulation layer, the insulation fireproof layer 2 and the outer glass fiber coil are connected as an integrated structure;

Here, the mold cavity-horizontal through hole for polyurethane foam molding is preliminarily set on the heat-preservation and fire-proof layer 2, so that the polyurethane foam raw material liquid flows into the above-mentioned level during the process of foam molding to prepare the polyurethane rigid foam insulation layer. In the through hole, it is solidified and molded together with the hard polyurethane foam insulation layer, so that the hard foam polyurethane solidified and formed in the horizontal through hole after the polyurethane foam molding is completed will combine the inner glass fiber coil, polyurethane hard foam insulation layer, heat preservation and fire protection Layer 2 and the outer glass fiber coil are tightly connected together to form a one-piece structure. Since the hardness and strength of polyurethane are relatively large, both of which are significantly greater than those of rock wool, here the hardness and strength from the horizontal to the through hole Polyurethane foam is used as the main supporting connecting bridge to support most of the weight of the insulating layer 1, the thin plastering surface layer and the decorative layer. The insulating and fireproof layer 2 made of rock wool is only used as an auxiliary supporting connecting bridge to support Connecting the thermal insulation layer 1, a small part of the weight of the thin plastered surface layer and the decorative layer, thus greatly reducing the weight of the connection supported by the rock wool in the traditional multi-layer prefabricated composite thermal insulation board, greatly reducing the burden of the rock wool, It is replaced by rigid polyurethane foam with higher support and connection capacity, which embodies the principle of more work for those who can, and improves the overall rigidity of the above-mentioned prefabricated composite thermal insulation fireproof board and the external thermal insulation system of thin plastered external walls made of it;

In this embodiment, the openings at both ends of the horizontal through hole are flaring structures, and the flaring structure makes the rigid polyurethane foam obtained by curing and molding at the flaring place be cone-shaped, and the cross-section of the cone-shaped structure is along the horizontal direction. The direction from the inside of the through hole to the outside of the hole gradually becomes larger, and reaches the maximum at the two ends of the through hole horizontally, so that the clamping contact area between the rigid foam polyurethane and the thermal insulation and fireproof layer 2 can be enlarged, and the clamping force can be improved. Reinforcement and support connection effect.

The glass fiber coils in this application are commonly used surface coils in polyurethane composite insulation boards in the prior art. They are prior art and commercially available. This application has no special restrictions on their types and specifications. The types and specifications in the technology are sufficient.

In addition, in order to solve the problem that the hardness and strength of rock wool in the prior art are so small that the core of the thin plastered external wall external insulation system made of it is soft and the two sides are hard and heavy, rock wool is used as the only supporting connection Bridges are used to support all the weights of organic insulation boards, thin plastered surfaces and finishes. The burden borne by rock wool is too heavy. The plastered surface layer and decorative layer lead to the overall looseness of the thin plastered external wall insulation system, and the overall rigidity is poor, resulting in the rock wool boards in the thin plastered external wall insulation system also easily along its length after the installation is completed. The layered tearing in the direction of the wide surface causes the failure of the external thermal insulation system of the thin plastered exterior wall, and the problem of safety accidents is likely to be caused by falling off at high altitudes.

The steel nail 11 is inserted into the internally threaded pipe 6 to move, interpolate and squeeze the anchor nail head 10 along the horizontal direction from outside to inside so that the anchor nail head 10 expands and becomes thicker;

Several reinforcement anchors are evenly distributed on the prefabricated composite thermal insulation fireproof board;

In this embodiment, the hard plastic material of the reinforcement anchor can be the same as the plastic material of the insulation nail used to penetrate the anchor insulation board in the prior art;

Since rigid foam polyurethane is a foaming hollow part, and the above-mentioned reinforcement anchor is a hard plastic solid part, the hardness and strength of the reinforcement anchor are far greater than that of rigid foam polyurethane. Here, the reinforcement anchor made of hard plastic is used as the main The supporting connection bridge is used to support and connect most of the weight of the insulation layer 1, the thin plastered surface layer and the finishing layer. The insulation and fireproof layer 2 made of rock wool is only used as an auxiliary supporting connection bridge to support and connect the insulation layer 1 , a small part of the weight of the thin plastering surface layer and the decorative layer, the supporting connection effect of the reinforced anchor is better than that of the above-mentioned hard foam polyurethane, thus greatly reducing the traditional multi-layer prefabricated composite insulation board. The weight of the connection supported by the cotton greatly reduces the burden of the rock wool, and it is borne by the reinforced anchor with a higher supporting connection capacity. The overall rigidity of the thinly plastered external wall external thermal insulation system thus solves the above-mentioned problems in the prior art.
