Abstract

The invention relates to a new type of blending agent used in the production of light-burned magnesium building materials that can replace magnesium chloride, comprising the following raw materials and contents: 10 kg of ferrous sulfate, 0.1 kg of triethanolamine, 27 kg of magnesium sulfate, 8 kg of magnesium silicate, and sodium silicate 6kg, aluminum dihydrogen phosphate 2kg, amorphous silicon dioxide 15kg, ammonium sulfate 6kg, bentonite 4kg, starch phosphate 7kg, aluminum potassium sulfate 1kg, titanate-NDZ-2010.05kg, water 260kg. The invention is used to produce light-burned magnesium building materials and can replace magnesium chloride as a new type of blending agent. It has good stability, no change after 6 months of storage, and has wide applications. The product has no burning, no steaming, no burning, and good wear resistance. , high hardness, high compressive strength, convenient processing, fast curing, easy nailing, easy sawing, bright surface, good formability, etc., can be used in the construction industry to make fireproof boards, fire doors, partition boards, corrugated tiles, ventilation pipes etc.

Description

technical field [0001] The invention relates to a blending agent for producing building materials, in particular to a novel blending agent for producing light-burned magnesium building materials that can replace magnesium chloride. Background technique [0002] Since the invention of magnesium oxychloride cement by the Frenchman Sorrell in 1986, magnesium chloride has been used as a blending agent for lightly burned magnesia to produce building materials. Adding magnesium chloride to light-burned magnesia can not only accelerate the hydration rate of magnesia, but also react chemically with magnesia to generate new hydration substances, speed up the coagulation time, and obtain products with higher strength. Magnesium oxide is an alkaline substance with a molecular formula of MgO. At present, magnesite or dolomite ore is generally calcined and crushed at home and abroad. The main component of magnesite or dolomite ore is magnesium carbonate. When the temperature after calci...
