High-strength fireproof insulation board with tongue-and-groove structure and manufacturing method of high-strength fireproof insulation board

Abstract

The invention relates to a high-strength fireproof insulation board with a tongue-and-groove structure and a manufacturing method of the high-strength fireproof insulation board. The insulation boardcomprises upper layer color steel, a common rock wool board and lower layer color steel, and the common rock wool board is located between the upper layer color steel and the lower layer color steel.The upper surface and the lower surface of the common rock wool board are bonded with the upper layer color steel and the lower layer color steel correspondingly, the upper layer color steel and the lower layer color steel are connected in a pressing mode at the left ends and the right ends to form a tongue and groove, the tongue and groove is provided with a cavity, the cavity is internally provided with a high-density rock wool filling block, the cavity of the tongue and groove is filled with the high-density rock wool filling block, the left end and the right end of the common rock wool board are flush cutting surfaces, the inner end of the high-density rock wool filling block is tightly attached to the cutting surface of the common rock wool board, and the outer end of the high-densityrock wool filling block is tightly attached to an inner cavity wall of the tongue and groove. Compared with the prior art, the tongue and groove is good in insulation performance, a high-density rockwool material is adopted, the hardness is high, the smooth insertion connection of the tongue and groove is ensured, and the high-strength fireproof insulation board has the advantages of good insulation performance, high strength, fire prevention and the like.

Description

technical field [0001] The invention relates to a thermal insulation board, in particular to a high-strength fireproof thermal insulation board with a tongue-and-groove structure and a manufacturing method thereof. Background technique [0002] At present, there are two ways to deal with the tongue and groove of the color steel rock wool insulation board commonly used in the market, one is to leave the tongue and groove empty, and the other is to fill the tongue and groove with polyurethane. The defect of the former is that there is energy loss at the groove and the strength of the groove is low; the defect of the latter is that the groove is not fireproof. [0003] Chinese patent CN201474224U discloses a wall composite board, the composite board includes an upper color steel plate, a core material made of glass wool or rock wool and a lower color steel plate, the core material is located between the upper color steel plate and the lower color steel plate , the upper end su...

The defect of the former is that there is energy loss at the groove and the strength of the groove is low; the defect of the latter is that the groove is not fireproof

[0003] Chinese patent CN201474224U discloses a wall composite board, the composite board includes an upper color steel plate, a core material made of glass wool or rock wool and a lower color steel plate, the core material is located between the upper color steel plate and the lower color steel plate , the upper end surface and the lower end surface of the core material are respectively bonded with the upper color steel plate and the lower color steel plate, and the two ends of the composite plate are provided with a tongue-and-groove structure that is inserted into each other; The filler is polyurethane foam. Since the highest combustion grade of polyurethane is Class B "flammable", its anti-combustion effect is poor.

[0005] Filling the rebate with solid material is currently a difficult problem in production, because the sealing and waterproof performance of the rebate needs to be considered. If the rock wool is cut, it is generally difficult to meet the cavity structure requirements. Cutting the rock wool and putting it into the rebate often causes problems. As a result, the rock wool cannot be filled with grooves
