Abstract

The invention discloses an inorganic early-strength and quick-setting material, which is characterized in that the inorganic early-strength and quick-setting material is mainly prepared from magnesium oxide, sodium hydroxide, magnesium dihydrogen phosphate, aluminum dihydrogen phosphate, retarder, short fiber, filling material and water according to a certain weight proportion; and the inorganic early-strength and quick-setting material can be formed by direct casting or mould casting, or be prepared into various products by extrusion forming. The material disclosed by the invention is simple and convenient to operate, excellent in physical performance, good in density, leakage-resistant, acid and alkali corrosion-resistance, low in manufacturing cost, and environment-friendly in material and preparation process, wide in application range, wide in application prospect and the like. The material is simple and convenient in preparationand forming process and low in cost, and is not only suitable for the small-scale manual manufacturing but applicable to the large-scale industrial production. The material is suitable for preparing the artist decoration, the section bar, the tank body, the framework, the board and the civil construction engineering, and is capable of replacing the silicate cement, the glass fiber-reinforced plastic, the ceramic, the plastic, the metal, the wood material and other materials on many aspects.

Description

Technical field [0001] The invention is an inorganic early-strength and fast-setting material. This material is actually an inorganic early-strength and fast-setting material. The material cost is low, the preparation and molding process is simple, the early fluidity of the material is good, the setting time is fast, and the early strength is high. , environmentally friendly and harmless, not only suitable for small-scale hand-made, but also suitable for large-scale industrial production, suitable for making craft decorations, profiles, tanks, frames, plates and civil engineering projects. Background technique [0002] Inorganic early-strength and fast-setting materials have the characteristics of short setting time, high early strength, acid and alkali corrosion resistance, and good material stability. The research time of this kind of early-strength and fast-setting materials in my country is relatively short, and the application range is small. This type of inorganic earl...
