preparation example Construction

[0026] The embodiment of the present invention also provides a method for preparing a fireproof board, which includes the following steps: uniformly mixing metamorphic marble powder, reinforcing fiber, flame retardant, Portland cement and dispersant and pulverizing to obtain a mixed powder; mixing The powder is pressure-molded in a fixed mold.

[0027] The raw materials in the fireproof board of the present invention are added and mixed according to their respective proportions, crushed and then pressurized and formed in a fixed mold, and the hydraulic pressure is approximately 40-70 MPa. During the mixing process, a mechanical stirring device can be used to make the mixing more uniform.

[0028] Preferably, after molding, it can also be dried at a constant temperature to speed up the drying rate, and then cooled naturally after drying.

[0029] Specifically, the preparation process of the mixed powder includes: grinding metamorphic marble powder, reinforcing fiber and Portla...

Embodiment 1

[0032] This embodiment provides a kind of fire-proof board, and it is made of various raw materials, and counts by weight parts, and various raw materials include 25 parts of metamorphic marble powders, 6 parts of glass fibers, 3 parts of self-sulfidyl urea, 20 parts of silicic acid salt cement and 3 parts calcium stearate.

[0033] This embodiment also provides a method for preparing a fireproof board, which includes the following steps:

[0034] Mix 25 parts of metamorphic marble powder, 6 parts of glass fiber, 3 parts of self-mimidyl urea, 20 parts of Portland cement and 3 parts of calcium stearate and pulverize to obtain a mixed powder; mix the mixed powder with water to obtain The solution with a mass fraction of 50% is poured into a fixed mold for press molding, and the pressure of the hydraulic press is 50 MPa.

Embodiment 2

[0036] This embodiment provides a fireproof board, which is made of various raw materials. In parts by weight, the various raw materials include 40 parts of metamorphic marble powder, 15 parts of carbon fiber, 10 parts of zinc borate, 30 parts of Portland cement and 10 parts polyethylene glycol.

[0037] This embodiment also provides a method for preparing a fireproof board, which includes the following steps:

[0038] First, 40 parts of metamorphic marble powder, 15 parts of carbon fiber and 30 parts of Portland cement were ground to 1000 mesh to obtain a first mixed powder.

[0039] Secondly, the first mixed powder was stirred and mixed with 10 parts of zinc borate and 10 parts of polyethylene glycol at a temperature of 50° C. to obtain a mixed powder.

Abstract

The invention discloses a fireproofing panel and a preparation method thereof, relating to the technical field of material preparation. The fireproofing panel is prepared from multiple raw materials in parts by weight: 25-40 parts of metamarble powder, 6-15 parts of reinforced fibers, 3-10 parts of a flame retardant, 20-30 parts of Portland cement and 3-10 parts of a dispersing agent. The preparation method of the fireproofing panel comprises the following steps: uniformly mixing the metamarble powder, the reinforced fibers, the flame retardant, the Portland cement and the dispersing agent, and crushing, so as to obtain mixed powder; and carrying out compression formation on the mixed powder in a fixed mold. The panel prepared by virtue of the formula and the preparation method has very excellent flame retardance, is relatively low in manufacturing cost and has a very good market application value, and the method is simple and feasible.

Description

technical field [0001] The invention relates to the technical field of material preparation, and in particular to a fireproof board and a preparation method thereof. Background technique [0002] Fire-resistant board, also known as fire-resistant board, has the characteristics of wear resistance, high temperature durable consumer goods, scratch resistance, impermeability, and easy cleaning. With the improvement of people's living standards, the requirements for building materials are getting higher and higher, and they are not satisfied with the single-function panel structure. [0003] However, the fireproof performance of the existing board structures is poor, and the fireproof boards generally have low manufacturing costs. Contents of the invention [0004] The object of the present invention is to provide a fireproof board, aiming at improving the flame retardancy of the board and reducing the production cost of the board. [0005] Another object of the present inven...
