Description
Technical field
The present invention relates to coating material production technical field, particularly relate to a kind of easy working weather-proof anticorrosion carbamide paint and preparation method thereof and using method.
Background technology
Along with the high speed development of national economy, standard of living and the level of consumption of people are more and more higher, as a kind ofly integrating leisure, amusement, avoid heat, the floating theme park of body-building etc. also arises at the historic moment.Build from the perfume (or spice) of first floating theme park in Asia flood ocean park, recent two decades comes, especially nearly ten years, and domestic newly-built in a large number floating theme park.Water garden are exposed to open air, except the some months of the phase of closing a business, water garden be in for a long time under water or alternation of wetting and drying environment in.Coating protection is not carried out in the ground of early stage water garden, is directly concrete surface, and the accumulation of salt in the surface soil, cracking, raw algae, shedding very easily appear in concrete surface, the problem such as to leak, and bring negative impact to water quality and water storage.Concrete surface adds ceramic tile, the advantages such as ceramic tile intensity is good, easy to clean can be utilized to overcome the defect of concrete surface, but the deficiency of ceramic tile is that it easily comes off, not easily repairs, and have ceramic tile to stitch.In addition, also can on concrete surface brushing paint, as urethane and esters of acrylic acid coating or carbamide paint etc.Urethane and esters of acrylic acid coating weather-proof, but can not long period of soaking under water.Carbamide paint have snappiness good, do not ftracture, the outstanding advantage such as chemical resistance is good, wear-resisting, weather-proof, curing speed is fast, waterproof, anticorrosion and terrace etc. can be widely used in.But existing carbamide paint is based on spray polyurea, need the equipment using price high by the workmen of specialty to construct, curing speed is fast, and poor adhesive force, not easily repairs.
Summary of the invention
The object of the invention is to the defect for overcoming prior art, and a kind of weather-proof, anticorrosion and easy working carbamide paint is provided, and the preparation method of this kind of coating and using method.
For achieving the above object, the present invention is by the following technical solutions:
