Magnesite fiber reinforced inorganic material

Abstract

The invention provides a magnesite fiber reinforced inorganic material. The magnesite fiber reinforced inorganic material is characterized by comprising the following raw materials in percentage by weight: 50 to 70 percent of magnesia, 10 to 25 percent of solid low-alkali cement, 20 to 30 percent of hemihydrate gypsum, 8 percent of urea-formaldehyde glue, 1 percent of phosphoric acid, 1 percent of ammonium chloride and 9 percent of magnesium chloride (MgCl2), and comprising a platinum clamp pot glass fiber grid cloth. The magnesite fiber reinforced inorganic material mainly has the following advantages: attractive appearance and modeling, no burr, smooth inside and outside, acid and alkali-resistance, corrosion resistance, high temperature resistance, freeze-tolerance, insolation resistance, aging resistance, no cracking, no toxicity, no pollution, no rust, no fracture, long service life, sound absorption, sound insulation, flame retardancy, fire resistance, capacity of being sawn, drilled, nailed, cut and scraped, simple preparation method, easily obtained raw materials, low cost, light weight, wide application, and capacity of being made into various products in different shapes, different specifications and different colors.

Description

technical field [0001] The invention relates to a magnesite inorganic glass steel, in particular to a ratio and a preparation method of the magnesite inorganic glass steel. Background technique [0002] Inorganic FRP, also known as FRIM (Fiber Reinforced Ionorganic Material), is a glass fiber reinforced magnesium oxychloride cement inorganic composite material. It is not made of organic resin but a composite material that uses inorganic materials as reinforcing materials. Its main materials are inorganic raw materials magnesia (the main component is magnesium oxide), brine (magnesium chloride aqueous solution), and medium-alkali glass fiber cloth. [0003] Inorganic FRP has various excellent properties, such as low cost, easy production and forming, fire prevention, waterproof, environmental protection, non-toxic, no peculiar smell, no deformation, no cracking, no broken, no paint peeling, no leakage, high and low temperature resistance, Inexpensive and widely used.

Problems solved by technology

The biggest disadvantage of magnesium chloride is that it will return to halogen when it encounters high temperature and humidity.

The main raw materials of magnesite products are magnesium oxide and magnesium chloride, but magnesium chloride contains a large amount of sodium chloride, and the sodium ions in the crystal voids can move, making the surface of the product easy to weather, deliquescence, and even lose luster, and pulverization occurs. Significant decrease in structural strength
