Embodiment Construction

[0015] The present invention will be further elaborated below in conjunction with embodiment.

[0016] A method for producing roof rock wool boards, said method comprising the following steps:

[0017] Step 1, raw material preparation:

[0018] Mix basalt, fly ash, gabbro, iron ore, bauxite, wollastonite and melt them into a liquid mixture. Among them, the raw material components include: basalt 10-20%, fly ash 14-30%, gabbro 2.8-6.8%, iron ore 1.2-6.2%, bauxite 20-35%, Wollastonite 25-45%.

[0019] Step 2, preparation of hydrophobic liquid:

[0020] According to the percentage by weight: SILRESBS1042 0.3-0.5%, methyl cellulose 5-8%, polyacrylamide solution 1-2%, the rest is phenolic resin and mix evenly.

[0021] Step 3, fiber preparation:

[0022] The liquid mixture is continuously flowed into the high-speed rotating centrifugal roller, and the liquid mixture is condensed into filamentous fibers under the action of centrifugal throwing and air cooling. Spray on rock wo...

Abstract

The invention discloses a roof rock wool board production method. The method comprises the following steps that 1, raw materials are prepared; 2, hydrophobic liquid is prepared; 3, fiber is prepared;4, a fibrous body is prepared; 5, the fibrous body is compressed, wherein a flat extrusion machine is adopted for extruding the fibrous body; 6, a finished product is prepared, wherein the extruded fibrous body is cut into a roof rock wool board with the preset size through a cutting tool. Accordingly, the prepared roof rock wool board has high compressive strength and point load capacity, the loading requirements of construction personnel and equipment can be met, and the roof rock wool board has the effects of heat preservation, thermal insulation, fire prevention, sound insulation and noisereduction.

Description

technical field [0001] The invention relates to the technical field of rock wool boards, in particular to a method for producing roof rock wool boards. Background technique [0002] Rock wool board is an inorganic fiber board made of basalt as the main raw material and processed by high-temperature melting. Rock wool board is also called rock wool insulation decorative board. Rock wool board is an artificial inorganic fiber processed by high-temperature melting. It has the characteristics of light weight, small thermal conductivity, heat absorption, and non-combustibility. The initial development is a common application type in construction, and it is mostly used in industrial buildings. Application Types and Basic Requirements". Rock wool board is a new type of heat preservation, flame insulation and sound absorption material. [0003] However, among the roofing rock wool board products, the existing roofing rock wool board products have high water absorption and low com...
