Embodiment 1

[0004] Example 1: Weigh the sieved particle size to be 15mm~35mm and the density to be 160~180kg / m 3 Place 100Kg of foam glass in the forming mold, prepare and weigh 250Kg of cementitious material. The preparation method of cementitious material is as follows: first blend industrial magnesium chloride and water, then add phosphoric acid and boric acid and stir evenly, then add Lightly burn the magnesia and stir evenly. At the same time, add hydrogen peroxide in the process of uniform stirring and stir evenly to form the gelling material. Finally, the gelling material is poured into the forming mold, the mold cover is covered, and the mold is naturally cured and set. The invention can be obtained by curing.

[0005] There are 3 kinds of weighing weights for the distribution ratio of each group of the cementitious material in this embodiment, and the total is:

[0006] 1. (Light burned magnesium oxide 46 + industrial magnesium chloride 26 + hydrogen peroxide 1.5 + phosphoric acid 0....

Embodiment 3

[0014] Example 3: Weigh the sieved particle size to be 15mm~35mm and the density to be 160~180kg / m 3 Place 126Kg of foam glass in the forming mold, prepare and weigh 171Kg of cementitious material. The preparation method of the cementitious material is as follows: first mix industrial magnesium chloride and water, then mix in phosphoric acid and boric acid and stir evenly, then mix in Lightly burn the magnesia and stir evenly. At the same time, add hydrogen peroxide in the process of uniform stirring and stir evenly to form the gelling material. Finally, the gelling material is poured into the forming mold, the mold cover is covered, and the mold is naturally cured and set. The invention can be obtained by curing.

Abstract

This invention relates to a method for preparing fireproof and heat-insulating board for architectures. The fireproof and heat-insulating board comprises aggregate and gel material at a weight ratio of (100-150):(100-250). The gel material comprises: light-burned MgO 46-56 wt.%, industrial MgCl2 20-26 wt.%, H2O2 1.5-3.5 wt.%, H3PO4 0.2-0.3 wt.%, HBO3 0.2-0.3 wt.%, and water 20-26 wt.%. The method comprises: (1) screening foam glass (particle sizes are 15-35 mm, and density is 160-180 kg / m3), and placing in a mold; (2) adding industrial MgCl2 and water; (3) adding H3PO4 and HBO3, and stirring uniformly; (4) adding light-burned MgO, stirring uniformly, and adding H2O2 during stirring to obtain a gel material; (5) pouring the gel material into a mold; (6) covering the lid, and curing naturally; (7) demolding, and maintaining. The fireproof and heat-insulating board has such advantages as low weight, high strength, high impact resistance, no deformation, good heat, sound, fire and water resistance, and good processability.

Description

[Technical Field] [0001] The invention relates to a building decoration fireproof material, in particular to a building fireproof insulation board used for a fireproof isolation belt and an inner partition wall and a preparation method thereof. [Background technique] [0002] With the rapid development of building technology, the technical indicators of building materials are getting higher and higher. However, the existing fire-proof insulation board has large investment but low output, large capacity, poor thermal insulation performance, high water absorption and moisture absorption, and sound insulation effect. Defects such as poor. [Summary of the Invention] [0003] The technical problem to be solved by the present invention is to provide a building fire insulation board which is light in weight, has good fire insulation performance and is convenient to manufacture, and a preparation method thereof. The technical solution adopted by the present invention to solve its techni...
