Abstract
The invention relates to a polyurea coating as well as a preparation method and application thereof. The polyurea coating is a polyurea elastomer; a polyurea coating spraying method adopts a polyurea elastomer spraying technology; in the polyurea coating spraying process, anti-skidding aggregate is added, which can be silicon carbide or rubber granules; and the polyurea coating is used as an anti-skidding material for the bridge surface of an aluminium alloy pedestrian bridge. Compared with the conventional paving materials, the polyurea coating has the characteristics of quick formation, insensitivity to dampness, wear resistance, skid resistance, as well as good adhesion, smooth surface, capability of spreading the anti-skidding aggregate and the like; and due to excellent toughness, the polyurea coating can completely resist heat expansion and cold contraction caused by change of ambient temperature in the day and at night and in four seasons, does not crack and shed off, and has a wide application prospect in the field of material protection.
Description
Technical field
The present invention relates to a kind of polyurea coating and preparation method thereof and purposes, belong to the anti-skidding field of environmental protection.
Background technology
Spray Polyurea Elastomer (SPUA) technology is nearly recent decades of the U.S., after low (nothings) such as high solid coating, water-borne coatings, radiation curable coating, powder coating pollutes application techniques, a kind of Novel solvent-free, the free of contamination green construction technology developing, develop for adapting to the environmental protection demand.This technique belongs to rapid reaction spraying system, and material system does not contain solvent, curing speed is fast, can be very easily sagging in the coating of facade, curved surface spraying tens mm thick and not.The SPUA versatility has been broken through the limitation of Traditional Environmental-protection type application techniques.This technology enters China, just obtains swift and violent development.Large quantities of key state projects utilizations in full swing such as the wear-resisting engineering of China national grand theater man-made lake, Beijing Olympic gymnasium series grandstand polyurea water-proof, National Games gymnasium, Shandong polyureas series engineering, Beijing-Tianjin high ferro polyurea water-proof, Beijing-Shanghai express railway polyurea water-proof, Huaneng Group power plant metal tin are anticorrosion.
At present, polyurea coating and spraying technology thereof just are applied to anticorrosion, waterproof field, but it is anti-skidding that, waterproof anticorrosion for not only needing on the aluminium alloy overpass bridge floor also needs, and polyurea coating and spraying technology thereof also do not apply to the anti-skidding field of aluminium alloy overpass bridge floor.
Summary of the invention
Technical problem to be solved by this invention provides a kind of polyurea coating and preparation method thereof and purposes, meets the anti-skidding requirement of aluminium alloy overpass bridge floor, simultaneously environmental protection, anticorrosion waterproof, but life-time service.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of polyurea coating, described polyurea coating are polyurea elastomer.
The invention has the beneficial effects as follows: compare with traditional pavement, polyurea coating not only have moulding fast, to characteristics such as moisture are insensitive, wear-resisting, anti-skidding, but but also have the characteristics such as sticking power is good, the anti-skidding pellet of surface smoothing spreading; Simultaneously, because its excellent snappiness, can resist round the clock fully, four seasons variation of ambient temperature is brought expands with heat and contract with cold, and can not produce cracking and obscission, have broad application prospects in the material protection field.
Another technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of preparation method of polyurea coating, the preparation method of described polyurea coating adopts spray Polyurea Elastomer Technology.
The spraying technology that the invention has the beneficial effects as follows polyurea coating adopts Spray Polyurea Elastomer (SPUA) technology, this technology is a kind of Novel solvent-free, free of contamination green construction technology, mainly by following characteristics: (1) quick solidifying, the facade continuous spray does not trickle; (2) 100% solid contents meet environmental requirement, especially are fit to the construction of reservoir walls; (3) coating fine and close, without seam, medium-resistance is very outstanding, can tolerate the erosion of water, acid, alkali, salt, wet goods medium, and is of many uses; (4) sticking power is good, and life-time service is non-foaming, do not come off, hollowing not; (5) ultraviolet resistance is aging, out of doors not efflorescence of life-time service, does not ftracture; (6) with respect to urethane resin, polyureas is insensitive to moisture, moisture, is not subjected to the impact of envrionment temperature, humidity during construction; (7) use temperature wide ranges can be at-50～150 ℃ of lower life-time service; (8) once construction namely reaches thickness requirement, overcomes the shortcoming of in the past multilayer construction.
Can use the less spray gun in construction of work output during construction, GX-8 spray gun for example can obtain the surface layer of even thickness like this.
On the basis of technique scheme, the present invention can also do following improvement.
Further, add anti-skidding pellet in the process of described Spray Polyurea Elastomer, described anti-skidding pellet is silicon carbide or rubber grain.
The beneficial effect that adopts above-mentioned further scheme is that the polyurea coating behind the anti-skidding pellet of introducing has better non-skid property, and has increased comfortableness.
Another technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of purposes of polyurea coating, described polyurea coating is as the anti-slip material of aluminium alloy overpass bridge floor.
The invention has the beneficial effects as follows that polyurea coating has good non-skid property, its frictional coefficient and nonskid paint are suitable, but can be pliable and tough have a surplus but rigidity is pure, fine and close, without seam, the fully infiltration of moisture and oxygen in the secluding air, anti-skidding, anticorrosion and barrier propterty is better; Polyurea coating has not only that good physical performance, hardness are moderate, smooth surface, from the smooth and level characteristics such as effective, and in engineering is used, kept polyurea coating solvent-free, insensitive to moisture, reached the requirement of waterproof.
