Description
Technical field
The invention belongs to mine down-hole shaft equipment Material Field, and in particular to a kind of steel member is answered with two-component polyureas
Close the shaft equipment material formed.
Background technology
Existing mine down-hole equipment material antiseptic mode used has steel paint, steel galvanizing and spray zinc, steel external application glass
Glass steel composite material and pure glass fiber reinforced plastics composite material.Steel paint in the environment of the moist, medium that is corrosive service life compared with
Short and paint top layer is not wear-resisting, needs regular maintenance and replacing；Steel external application glass-reinforced plastic material is deposited due to the limitation of manufacturability
There is the defects of stomata, bad mechanical strength in glass fiber reinforced plastic surface layer, rust water phenomenon occurs in use, drops its intensity
Low, service life shortens；Steel galvanizing and spray zinc is not wear-resisting, and easily corrosion phenomena occurs to coating in abrasion during for cage guide, contracts
Short service life.Pure glass-reinforced plastic material by during external force due to that can be deformed, it is impossible to meet the length of the larger section bar such as cage guide and buntons
Phase requirement.
The content of the invention
The purpose of the present invention is to overcome above-mentioned many disadvantages, there is provided a kind of quality is homogeneous, production efficiency is high, compact structure,
Extremely abrasive, appearance looks elegant, service year limit for length, non-maintaining steel-polyureas cage guide, a kind of preparation method of buntons.The material
It can be well positioned to meet long-term use of under moist, acid medium Minepit environment.
The purpose of the present invention can be reached by following measures：
A kind of Novel steel-polyureas cage guide, the preparation method of buntons, it is characterised in that comprise the following steps：
A, the pretreatment of steel：Steel are derusted and correction process；
B, the surface treatment of steel：Spray-applied primer is carried out to steel；
C, two-component polyureas and steel are compound：It is made up of the mixing of the raw material such as semi-prepolymer, amine terminated polyether, chain extender, auxiliary agent
Two-component materials, through hydraulic pressure spray gun, the steel surface of even application after treatment, crosslinking curing in the short time is close with steel
It is bonded in one in fact.
Traditional steel surface derusting mainly passes through mechanical derusting, and the present invention selects new derusting work to steel surface
The step of skill, mainly reaching derusting effect by steps such as ball blast and derustings by sandblasting, specifically handling steel rust removing is to throw
Ball machine and sand-blasting machine carry out Shot Blasting to steel member.
The glacing flatness of steel is completed by steel correction mechanical equipment, it is ensured that steel it is straight.
To steel member brushing or spray-applied primer, priming paint uses epoxy or modified epoxy priming paint, can also use other type
Priming paint.
In two-component polyureas manufacturing process, semi-prepolymer can be different for aromatic polyisocyanate, aliphatic isocyanate, MDI bases
Cyanate；Amine terminated polyether is polyether polyamine structure；Chain extender can be diol chain-extension agent, aromatics amine chainextender, aliphatic amine expansion
Chain agent etc.；One or more of the auxiliary agent in accelerator, pigment paste, age resister, antistatic additive；The wherein matter of semi-prepolymer
It is 60 ~ 90% to measure fraction, and amine terminated polyether mass fraction is 5-20%, chain extender content 1-10%；Semi-prepolymer is component 1, its
Remaining is component 2.
Two-component polyureas after hydraulic pressure or the extra quality impingement mix of pneumatic spraying equipment using component surface is sprayed on, to ensure to glue
Knot is firm, and crosslinking is abundant.
When being drilled to product, the requirements such as the quantity of drilling, size and location can directly be drilled according to drawing.
The component of the present invention has that appearance looks elegant, compact structure, production efficiency are high, quality is homogeneous, extremely abrasive, corrosion resistant
Erosion, flame-retardant and anti-static, it is non-maintaining, easy for installation, service life is long the advantages that, especially suitable for media such as underground humidity, acidity
Used in environment.Novel steel-polyureas cage guide, buntons are run in antiseptic property, quality stability and service life and cage
Comfort level higher than it is existing paint, galvanizing and spray zinc, external application glass-reinforced plastic material anti-corrosion mode steel components.
Embodiment
Example 1
From square steel or the steel component of other specifications and models by ball blast or blasting treatment after, it is thick to derust and increase surface
Rugosity.Steel component after Shot Blasting is corrected processing to it by steel shaping plant equipment, it is ensured that steel component
It is straight.
The steel surface after pretreatment is sprayed or brushed 1-3 times using epoxy finish or other priming paint, waits abundant table
Enter lower road step after dry.
By each semi-prepolymer of raw material 85%, 14% amine terminated polyether, 0.5% chain extender, 0.1% accelerator, 0.2% anti-aging
Agent, 0.1% antistatic additive, 0.1% pigment paste are clashed after mixing by dedicated hydraulic or pneumatic spraying equipment at certain temperature
In steel member surface spraying, a crosslinking curing shaping, steel-polyureas cage guide, each component of buntons are made.
Comparative example 1
In steel component external coating corrosion resistant coating.
Comparative example 2
Glass-reinforced plastic material is cladded with steel component
Comparative example 3
Galvanizing and spray zinc processing on steel component
Performance test
The cage guide that example 1 and comparative example 2,3 are obtained carries out the convenient test of anti-corrosion, stability, intensity.
1st, anti-corrosion mode and length of service contrast
1.1st, anti-corrosion mode：Steel surface brushing corrosion resistant coating（Comparative example 1）, this technique is traditional anticorrosion process, and antiseptic effect is poor,
Phenomenon of getting rusty was occurred as soon as using 3 years or so under normal conditions, if being used in mine down-hole rugged environment, the length of service is only
Have 5 years or so.
1.2nd, anti-corrosion mode：Steel surface is cladded with glass-reinforced plastic material（Comparative example 2）, this technique is traditional hand paste technique, is prevented
Rotten effect is slightly long with respect to the brushing corrosion resistant coating time, in the available also only 10-15 or so of mine down-hole.
1.3rd, anti-corrosion mode：Steel surface galvanizing and spray zinc processing（Comparative example 3）, this Process anti-corrosion effect relative contrast
Example 1, the anti-corrosion time of comparative example 2 approach, and can use in mine down-hole has 10-15 or so.
1.4th, anti-corrosion mode：Steel surface sprays two-component polyurea materials（Example 1）, this technique answered using steel with polyureas
Conjunction forms.Its antiseptic effect is good, can be used more than 30 years in the environment of moist and water drenching.
2nd, crocking resistance contrasts
Abrasion test is done under the same terms, using steel surface brushing corrosion resistant coating, steel surface heat dip zinc treating hardly antifriction
Wipe, it is 5% or so that steel surface, which is cladded with glass-reinforced plastic material friction loss quality, and the two-component polyurea materials of same volume are only damaged
Lose 0.3% or so.
3rd, impact strength contrasts
3.1st, anti-corrosion is painted：The impact strength of comparative example 1,3 is the intensity of steel in itself.
3.2nd, external application glass-reinforced plastic material：The steel of comparative example 2, its surface are cladded with fiberglass and play antisepsis, its anti-impact
Hit intensity is the intensity of material in itself.
3.3rd, two-component polyurea materials：The steel of example 1 have higher shock resistance, while also function to anticorrosion effect
Fruit, shock resistance will be much better than paint, galvanizing and the processing of spray zinc and external application glass-reinforced plastic material.
