Problems solved by technology

[0003] The glass magnesium board in the prior art usually uses magnesium oxide and magnesium chloride as forming agents. In order to make the magnesium fully and quickly condense, the content of magnesium chloride should not be too low, otherwise the purpose of making the magnesium fully and quickly condense cannot be achieved.
Not only that, the glass magnesium boards in the prior art are difficult to meet the requirements of national or industry standards in terms of flexural strength, impact strength, dry shrinkage rate, wet expansion rate, screw holding force, and non-combustibility at the same time, so that the limit The use of glass magnesium board in actual production

Abstract

The invention discloses a flame-retardant glass magnesium board and a production process thereof. The flame-retardant glass magnesium board is prepared from the following raw materials in parts by weight: 60-85 parts of light calcined magnesia, 30-45 parts of anhydrous magnesium sulfate, 5-10 parts of magnesium chloride hexahydrate, 8-16 parts of forsterite powder, 1-5 parts of decabromodiphenyl ether, 25-38 parts of a light filling material, 2.5-8 parts of a coupling agent, 0.6-1.8 parts of a water-resistant modifying agent and 50-70 parts of water. By taking magnesia and magnesium sulfate as the main components and adding multiple addition components, the flame-retardant glass magnesium board has quick-hardening property and early strength of a magnesium oxychloride gel material, the water tolerance is remarkably enhanced, and the breaking strength, the flame retardance and the thermal insulation are enhanced, so that the application range of the flame-retardant glass magnesium board is greatly expanded, and the flame-retardant glass magnesium board is suitable for being used as thermal insulation panels of indoor wall bodies and floors.

Description

technical field [0001] The invention relates to the field of building decoration materials, in particular to a flame-retardant glass magnesium board and a production process thereof.
