Abstract

This invention discloses a method for manufacturing a water-resistant ceramic paint. The method uses Al2O3 as the raw material, calcium aluminate cement (925#) as the adhesive, alpha-Al2O3 and SiO2 micropowders to improve the fluidity and processability, X-SiC as the wear-resistance improver, and NNO, ADS and FW 10 as the high efficiency composite additives. The ceramic paint has such advantages as high adhesiveness, high strength, good wear resistance, and good acid/base corrosion resistance. The GB/T3001-2000 flexural strength at room temperature is greater than or equal to 20 MPa, the YB/T5201-1993 flexural strength at room temperature is greater than or equal to 140 MPa, and the volume density is greater than or equal to 2.98 g/cm3. The ceramic paint can primarily coagulate within 3 d at room temperature, and completely coagulate within 28 d.

Description

A kind of wearable ceramic coat and preparation method thereof

[technical field]

The present invention relates to field of compound material, particularly a kind ofly can under the normal temperature state, be cured as wearable ceramic coat of similar pottery and preparation method thereof.

[technical background]

At present, cement concrete is the most large manufactured construction materials in the present age, China's cement annual production is above 500,000,000 tons, along with cement is adopted in a large number by construction project and building, cement industry has obtained significant progress in China, its processing equipment is generally vertical pulverizing mill, the vertical pulverizing mill that particularly German Lai Xieer company produces, be widely adopted in countries in the world, it is to produce powder particles by the principle of work that gas high speed impact and mechanical grinding combine to distribute little, thin and uniform particles cement products, but the liner plate of vertical mill and powder delivering pipe road are owing to the brute force that stands the high speed pulverized coal borne air flow is for a long time washed away, cause destroying and accelerate, traditional steel liner plate and metallic conduit can not satisfy rigorous environment like this again, cause damaging and accelerate, change frequently, cause the frequent break-down maintenance of enterprise, bring the heavy economical load and the wasting of resources to enterprise, the restriction enterprise development.

[summary of the invention]

The objective of the invention is at the deficiency in the above technology, provide a kind of overall performance good, adhesive power is strong, intensity is high, wear-resisting anti-washing away and wearable ceramic coat that the acid and alkali-resistance erosive can use under the normal temperature state and preparation method thereof.

The object of the present invention is achieved like this: the present invention adopts electric smelting abrasive material level palm fibre corundum (Al ₂O ₃) be main raw material, purpose is wedding agent in order to improve wear resisting property with the high grade aluminous cement, improves the ambient temperature mechanical properties of wearable ceramic coat, with bimodal active a-Al ₂O ₃Micro mist SiO ₂Micro mist is regulated and is flowed and workability, adds grand wear-resisting toughener of level of match and high efficiency complex additive, fully plays the normal temperature state

Be cured as the conversion of similar ceramic structure down and utilize steel fiber to increase the forced coupling effect.

Its preparation method is as follows: (unit weight part)

(1) elder generation is with the brown steel (Al of 1-3mm ₂O ₃) 44; 1mm palm fibre steel (Al ₂O ₃) 26; Add forced mixer, start was stirred one minute, allowed it on average be paved with the stirrer bottom.

(2) add CA-50 cement (electric smelting 925#) 26; Al ₂O ₃, SiO ₂Activate micro powder 4; Start was stirred 1-2 minute again.

(3) add the wear-resisting toughener X-SiC 1.25 of the grand level of match; High efficiency complex additive (NNO, ADS, FW ₁₀, 1: 1: 1 weight ratio) and 0.718, start is stirred 8 minutes to uniform state, but does not have the both blowing packs of caking of uniting, band internal liner package, 25 kilograms/bag.

[embodiment]

(1) processing of construction housing: the housing of should guaranteeing to be constructed is clean, at first tackles housing and adopts with means such as emery wheel polishing and emery cloth grindings, reaches no rusty scale, does not have oil, no spot.

(2) the welding requirements bar gauge of anchoring net is the 45# straight carbon steel of diameter 6mm, and weld spacing is 300mm, adopts spot welding to be no more than 150mm and welds a place.

(3) method of attachment of spreading anchoring rhombus steel mesh and isolation reinforcing bar that the isolation rebar surface will be smooth is spot welding, and the distance of spot welding should be less than 300 * 300mm, and removes mechanical welding slag.

(4) by 100 kilograms of stirrings, adding water will take by weighing the 6-8 kilogram with pound at every turn in the stirring of materials, and the limit adds the waterside and stirs.

(5) stirring to evenly adding 5.5 kilograms of steel fibers, added fashionable evenly adding while stirring, in case unite after 3-6 minute.Observation stirs and can begin operation, and the material amount time of putting can not be above 25 minutes.

(6) smear: disposablely will smear an integral body, the joint gap of partial smearing generally is not more than 5 hours.

(7) smearing thickness remains on 25mm, density 29g/cm ³When 15mm is following, can cancel the use of reinforcing bar as thickness.

(8) carry out after 2 press polish on ready-made wearable ceramic coat surface, and uniformly at the wearable ceramic coat surface sprinkling curing fluid capable of smearing, thickness is not more than 1mm.

(9) maintenance adopts the steam curing of resistive heating machine (YaLor-I) type to be not less than 7 days.

A kind of wearable ceramic coat of the present invention maintains initial set in 3 days and finishes under the normal temperature state, the final set phase is can reach GB/T3001-2000 strength at normal temperature 〉=20MPa, YB/T5201-1993 strength at normal temperature 〉=140MPa, volume density 〉=2.98g/cm in 28 days ³
