Problems solved by technology

The glass magnesium boards in the prior art usually use 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, and when magnesium chloride When the content of chlorine ion is in line with the purpose of making magnesium fully and quickly condensed, the content of chloride ion is too high, which will easily cause the board to absorb moisture and return to halogen
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 relates to architectural and decorative materials, in particular to a glass-magnesium plate comprising a forming agent, a reinforcement material, a light filler, a modifier and water, wherein the forming agent is magnesia, magnesium sulfate and magnesium chloride, the reinforcement material is a glass fibre grid fabric or other reinforcement materials, and the modifier comprises a whitening agent, a stabilizing agent and a toner. Compared with the prior art, the invention achieves the aims of stabilizing chlorine ions and preventing the moisture absorption and the halogen return of the glass-magnesium plate by lowering the content of the magnesium chloride and combining the stabilizing agent, also enhances the comprehensive performance of the glass-magnesium plate greatly under the combined action of the forming agent, the reinforcement material, the light filler, the whitening agent, the stabilizing agent and the toner and enables the glass-magnesium plate to reach or exceed the national or industrial standard requirement simultaneously in the aspects of folding strength, impact strength, drying shrinkage, bulking factor, screw holding capability, incombustibility and the like, so that the invention enhances the application range of the glass-magnesium plate greatly and can be widely used for the basal plate of plate materials, such as a grouting plate, a fire-proof plate, a ceiling plate, a decorative plate, a sound-absorbing plate, a partition plate and the like.

Description

technical field [0001] The invention relates to a building and decoration material, in particular to a glass magnesium board. Background technique [0002] The glass magnesium board is made of magnesium forming agent, glass fiber mesh cloth, filler, etc., through mechanical rolling, and is mainly used for indoor non-load-bearing walls and ceilings, as well as substrates for various decorative panels. 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, and when magnesium chloride When the content of chlorine ion is in line with the purpose of making magnesium fully and quickly condensed, the content of chloride ion is too high, which will easily cause the board to absorb moisture and return to halogen. Not on...
