A kind of anti-skidding anticorrosion deck composition of organosilicon and manufacture method thereof
technical field
The present invention relates to anti-skidding anticorrosion deck composition of a kind of organosilicon and preparation method thereof, belong to shipbuilding field.
technical background
At present, existing boats and ships, the common skid-resistant coating in ocean platform deck are classified by the kind of adding slipproofing agent, comprise following three classes:
One class is take inorganics sand grains as slipproofing agent, and as silica sand, quartz sand, glass hollow bead, silicon carbide, haydite, crystalline aluminum oxide etc., the feature of this class skid-resistant coating is: frictional force is large, raw material is easy to get, with low cost, but this slipproofing agent is than great, be mixed and easily precipitate with paint vehicle, the stifled rifle of spraying, has to take artificial stucco, deal with problems arising from an accident the sand not boning is swept, operating efficiency is low, and sand grains is irregular, although initial stage frictional force is large, but easy to wear coming off of later stage, application life is short;
Equations of The Second Kind slipproofing agent adopts organic compound pellet, as synthetic resins, waste rubber particle, although the price of this class slipproofing agent is higher than inorganic pellet, but there is suitable stiffness and elasticity, there is no arris edge, can stand friction and impact difficult broken, clinging power is good, difficult drop-off, and the initial stage is a little bit smaller compared with inorganic pellet frictional force, but the life-span is long, and proportion and base-material similar, not free settling, execute convenience, be suitable for spraying, pellet is even, but must prevent the phenomenon of pellet and solvent-swollen layering;
The 3rd class skid-resistant coating is without slipproofing agent pellet, is mainly that the binder resin of coating is carried out to molecular designing, and high reactivity group composition, produces strong polarity at coating surface, and Surface Contact produces moving resistance, and this skid-resistant coating is in the trial period at present.
Current skid-resistant coating is difficult to meet the service requirements of ship deck, mainly has following shortcoming: weathering resistance is bad, easily aging; Construction is complicated, and construction process contaminate environment operating efficiency is low; Sticking power and erosion resistance are not good enough; Replacing property of cold-and-heat resistent is poor etc.In modern industry and daily life, various corrosion are seen everywhere, especially in ocean engineer equipment in humidity, high salt, windy, blast air environment, for extreme environment, exposed parts are easily subject to serious corrosion, and reduced its work-ing life, and composition increases.Therefore, exploitation both had wear resistance, weather resisteant, sea water resistance and salt fog resistance, resistance to intensive ultraviolet, cold-hot alternately, etc. the anti-skidding anticorrosion deck composition of organosilicon of marine climate resistant of performance very important.
