Embodiment 1

[0007] Get dolomite powder to be 32kg, calcium polyphosphate to be 15kg, glyceryl caproate to be 27kg, glass fiber to be 13kg, aluminum oxide powder to be 12kg, silicon nitride to be 17kg, disodium hydrogen phosphate to be 6kg, put into stirring tank, use The mixer stirs evenly, puts the uniform slurry into the mold, extrudes, and dries at a temperature of 160°C to obtain a fireproof board containing calcium polyphosphate.

Embodiment 2

[0009] The preparation method is the same as in Example 1, and the content of each component in this example is: 29kg of dolomite powder, 21kg of calcium polyphosphate, 18kg of glyceryl caproate, 14kg of glass fiber, 13kg of aluminum oxide powder, and 13kg of silicon nitride. 14kg, disodium hydrogen phosphate is 8kg.

Embodiment 3

[0011] The preparation method is the same as in Example 1, and the content of each component in this example is: 27kg for dolomite powder, 18kg for calcium polyphosphate, 24kg for glyceryl caproate, 15kg for glass fiber, 14kg for aluminum oxide powder, and 14kg for silicon nitride. 15kg, disodium hydrogen phosphate is 10kg.

[0012] Fire performance test and results

[0013] Fire performance tests were carried out on the prepared fireproof boards of Example 1, Example 2, and Example 3, and the test standard was European Union EN 13501-1. The fire performance grades of Embodiment 1, Embodiment 2, and Embodiment 3 are A1, A2, and A1 respectively, which have very good fire performance and can improve the fire prevention capability of the purification workshop.

Abstract

The invention relates to a fireproof board containing calcium polyphosphate which is composed of the following components in parts by weight: 27-32 parts of dolomite powder, 15-21 parts of calcium polyphosphate, 18-27 parts of caproin, 13-15 parts of glass fiber, 12-14 parts of aluminum oxide powder, 14-17 parts of silicon nitride and 6-10 parts of disodium hydrogen phosphate. The fireproofing grade of the board containing calcium polyphosphate can reach A1 and A2; and thus, the board has favorable fireproof property.

Description

technical field [0001] The invention relates to a board, in particular to a fireproof board containing calcium polyphosphate. Background technique [0002] Fireproof panels have a wide range of uses and can be used in all aspects of life and production. With the enhancement of people's awareness of fire protection, people's demand for fire protection is getting higher and higher. If the fire resistance of the board is poor, if a fire occurs, heavy casualties will occur. In the construction process of the purification workshop, it is also necessary to carry out fireproof treatment on the board, so it is necessary for us to find a board with good fire resistance to overcome the problem of insufficient fire resistance of the existing board. Contents of the invention [0003] The technical problem to be solved: the problem of poor fire resistance of the board in the purification workshop. [0004] Technical solution: The invention discloses a fireproof board containing calci...
