Problems solved by technology

[0006] A large amount of resin glue is used in the compounding of existing rock wool composite boards. The resin glue contains a large amount of benzene and its derivatives, and these resin glues have not been subjected to high-temperature treatment, which will affect people's health. Carcinogenic, the present invention provides a buckle-type rock wool composite board. Under the condition that the strength of the rock wool composite board does not decrease, use as little or no resin glue as possible to reduce the impact of benzene and its derivatives in the resin glue on people. physical health effects

Embodiment 1

[0041] Such as Figure 1 to Figure 3 As shown, the buckle-type rock wool composite board of this embodiment includes a rock wool matrix layer 1, a reinforcement layer 2, a surface layer 3 and a buckle structure 4, and the reinforcement layer 2 is sandwiched between the rock wool matrix layers 1; the surface layer 3 is connected to the reinforcement layer 2 through the buckle structure 4, and the surface layer 3 is closely attached to the rock wool matrix layer 1.

[0042] Among them: the rock wool matrix layer 1 is made of basalt, blast furnace slag, fly ash, and waste rock wool blocks as raw materials, which are melted at high temperature, blown into fibers by high-speed centrifugal force or high-pressure gas, and are obtained by adding an appropriate amount of thermosetting resin adhesive and water-repellent agent. , the addition amount is 0.8-1% of the total mass, and its raw material is to increase the waste rock wool block, and the addition amount of the waste rock wool b...

Embodiment 2

[0047] The manufacturing method of the buckle type rock wool composite board of the present embodiment comprises the following specific steps:

[0048] Step S101, raw material preparation: mix 62% of blast furnace slag, 25% of basalt, 10% of fly ash, and 3% of waste rock wool block, wherein the particle size of basalt is 8cm, and the block diameter of waste rock wool block is 8cm , to feed the raw materials through the conveyor into the cupola to melt them into a liquid mixture;

[0049] Step S102, fiber preparation: the liquid mixture is continuously flowed into the high-speed rotating centrifugal rolls through the melt launder. Rotate, the upper and lower corresponding centrifugal rollers rotate in the same direction; the outer side of the centrifugal roller is surrounded by an air curtain formed by the blower, the liquid mixture is thrown four times by the centrifugal roller and condensed into silky fibers under the action of air cooling, the fiber filaments are After bein...

Embodiment 3

[0056] The manufacturing method of the buckle type rock wool composite board of the present embodiment comprises the following specific steps:

[0057] Step S101, raw material preparation: mix 62% of blast furnace slag, 22% of basalt, 13% of fly ash, and 3% of waste rock wool block, wherein the particle size of basalt is 8cm, and the block diameter of waste rock wool block is 8cm , to feed the raw materials through the conveyor into the cupola to melt them into a liquid mixture;

Abstract

The invention discloses a press buckle type rock wool composite board and a manufacturing method thereof, and belongs to the technical field of heat insulation material preparation. The composite board comprises rock wool base body layers, a reinforcing layer, a surface layer and a press buckle structure, wherein the reinforcing layer is arranged between the rock wool base body layers in a clampedway, and achieves the effects of supporting and reinforcement; the intensity of the rock wool base body layers is well enhanced, so that the overall intensity of the rock wool base body layers is improved by at least 100 times or higher; the surface layer is connected with the reinforcing layer through the press buckle structure, and is tightly attached onto the rock wool base body layer. Throughthe designed structure, the mode that the surface layer is adhered by polymer cement mortar in the prior art is changed; the polymer cement mortar is not used as much as possible; the emission of benzene and benzene derivatives is reduced; the use of the composite board is safer and more reliable; the heat insulation, sound insulation and fireproof effects are obvious.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation material preparation, and more specifically relates to a buckle-type rock wool composite board and a manufacturing method thereof. Background technique [0002] 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. The rock wool board products are suitable for industrial equipment, construction, and ships. Heat insulation, sound insulation, etc. The currently used rock wool composite boards add cement mortar / resin glue to the surface of the rock wool board, or apply resin glue on the surface of the rock wool board, and then adhere the surface layer through cement or resin glue. The surface layer is All kinds of decorative paintings, so the rock wool board not only has the function of heat insulation and fire prevention, but also th...
