Embodiment 1

[0034] Embodiment 1: 37kg of ordinary Portland cement of model PO42.5R, 1.7kg of sulphoaluminate cement of model 42.5, 55kg of quartz sand crossing 8-40 mesh sieve, 2kg of silica powder crossing 94 mesh sieve, two Water gypsum powder (CaO.2H 2 O) 0.4kg, water reducing agent (naphthalene sulfonate formaldehyde condensate) 0.4kg, (redispersible) latex powder (ethylene-vinyl acetate copolymer) 0.7kg, cellulose ether (400PFV) 0.15kg, fly ash 3kg , 0.16kg of polypropylene staple fiber with a length of 3mm.

[0035] When using, first weigh the above-mentioned components of dihydrate gypsum powder, sulfur silicate cement, water reducer, latex powder, cellulose ether and ordinary Portland cement according to the production formula ratio, pour them into the mixer for mixing and stirring, The stirring time is 10-15 minutes, and the small material is obtained after stirring evenly; then the quartz sand, fly ash, silica powder and polypropylene short fiber are weighed according to the pr...

Embodiment 2

[0041] Embodiment 2: 40kg of ordinary portland cement of model PO42.5R, 1.5kg of sulphoaluminate cement of model 42.5, cross the quartz sand 60kg of 8-40 mesh sieve, cross the silica powder 1.5kg of 94 mesh sieve, Dihydrate gypsum powder (CaO.2H 2 O) 0.45kg, water reducing agent (naphthalene sulfonate formaldehyde condensate) 0.35kg, (redispersible) latex powder (ethylene-vinyl acetate copolymer) 1kg, cellulose ether (400PFV) 0.1kg, fly ash 4kg, 0.1 kg of polypropylene staple fiber with a length of 3 mm. The method of making and using is the same as that of Example 1, so it will not be repeated.

Embodiment 3

[0042] Embodiment 3: 35 kg of ordinary Portland cement of model PO42.5R, 2 kg of sulphoaluminate cement of model 42.5, 50 kg of quartz sand crossing 8-40 mesh sieve, 2.5 kg of silica powder crossing 94 mesh sieve, two Water gypsum powder (CaO.2H 2 O) 0.35kg, water reducing agent (naphthalene sulfonic acid formaldehyde condensate) 0.45kg, latex powder (ethylene-vinyl acetate copolymer) 0.4kg, cellulose ether (400PFV) 0.2kg, fly ash 2kg, poly Propylene short fiber 0.2kg. The method of making and using is the same as that of Example 1, so it will not be repeated.

[0043]In a word, the invention has the advantages of high impact resistance and compressive strength, strong high temperature resistance, good wear resistance, long service life, environmental protection and low cost, and can be popularized and used.

Abstract

The invention relates to an anti-impact efficient wear resistant material which is made of the following raw materials with the following weight ratio: 35 to 40 portions of ordinary Portland cement, 50 to 60 portions of quartz sand, 1.5 to 2 portions of sulpho-aluminate cement, 2 to 4 portions of coal ash, 0.4 to 1 portion of emulsion powders, 0.35 to 0.45 portion of dihydrate gypsum powder, 1.5 to 2.5 portions of silica dioxide powder, 0.35 to 0.45 portion of water reducing agent, 0.1 to 0.2 portion of cellulose ether and 0.1 to 0.2 portion of polypropylene staple. By adopting non-poisonous environmental protective raw materials, the anti-impact efficient wear resistant material has the advantages of impact resistance and high anti-compression strength, strong performance of high temperature resistance, good durability, long service life, environmental protection and low cost.

Description

technical field [0001] The invention relates to an impact-resistant high-efficiency wear-resistant material. Background technique [0002] Currently used in metallurgy, coal, thermal power, chemical, cement and other industries such as slag flushing ditch, ore chute, coal unloading chute, hopper, material silo, flood gate and hopper used in water conservancy and hydropower, port and wharf projects, etc. The anti-abrasion material is coated on the outer surface of the foundation concrete, and its function is to protect the foundation concrete or steel silo from the damage of the external environment. There are many kinds of anti-wear materials on the market, the most common ones are ceramic plates, cast stone plates, calendered microcrystalline plates; iron filing mortar, iron filing concrete; stainless steel plates, nylon plates, polyethylene plates and rubber plates, etc. There are many traditional wear-resistant material profiles. In addition to being difficult to configu...
