Inorganic fiber reinforced composite material and preparation method thereof

Abstract

The invention relates to an inorganic fiber reinforced composite material which is characterized in that the composite material is prepared by magnesium oxide, phosphate, a retarder, short fibers, fillers and water according to a certain weight ratio; the composite material can be used to produce various products by mold pouring or pressure molding, and the operation is simple and convenient; the composite material has the advantages and effects of good mechanical properties, good density, acid and base corrosion resistance, nontoxicity, environmental protection, low cost and wide applications; and the inorganic fiber reinforced composite material has low cost, high strength, and good toughness, is applicable to industrial batch production, is suitable for producing pipes, tanks, decoration materials, handicrafts, fireproof doors and windows and the like with various shape specifications, and can substitute wood, metal, and plastics in many aspects.

Description

Technical field

[0001] The invention is an inorganic fiber reinforced composite material, which is actually a compound phosphate gelling material, with low material cost, simple preparation process, good initial fluidity, fast forming, high early strength, non-toxic, environmental protection, Pipes, tanks, decorative materials, handicrafts, fireproof doors and windows and other products of various shapes and specifications can be industrially produced by using mold casting and pressure forming technology. Background technique

[0002] Compound phosphate cementitious materials have the characteristics of fast setting, early strength, durability and stability. The research on it in our country started late, and there are not many applications at present. Compound phosphate gelling material is a gelling material formed by the acid-base reaction between acid phosphate and alkaline alkaline earth metal oxide. The material undergoes a chemical reaction at room temperature to soli...

Examples

Embodiment Construction

[0027] (1) get the raw materials ready according to the weight percentage of each of the following components:

[0028] Magnesium Oxide 35%

[0029] Potassium dihydrogen phosphate 20%

[0030] Zinc dihydrogen phosphate 5%

[0031] Borax 1.5%

[0032] Sodium polyphosphate 0.5%

[0033] Short Fiber 1%

[0034] Stone powder 10%

[0035] (2) Preparation of material slurry

[0036] Start the mixing vessel and add magnesium oxide, borax, sodium polyphosphate, potassium dihydrogen phosphate, zinc dihydrogen phosphate, stone powder, and short fibers in order while stirring, and mix well, and finally add water and stir for 3 minutes to obtain a material slurry .
