Description
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, the common skid-resistant coating in existing boats and ships, ocean platform deck, by the type classification adding slipproofing agent, comprises following three classes:
One class is with inorganics sand grains for slipproofing agent, and as silica sand, quartz sand, glass hollow pearl, silicon carbide, haydite, crystalline aluminum oxide etc., the feature of this kind of 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 with paint vehicle and easily precipitate, the stifled rifle of spraying, has to take artificial stucco, deal with problems arising from an accident and the sand do not bondd swept, operating efficiency is low, and sand grains is irregular, although initial stage frictional force is large, but the later stage is easy to wear to come off, and 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 kind of slipproofing agent is higher than inorganic pellet, but there is suitable stiffness and elasticity, there is no arris edge, friction can be stood and impact not easily 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 are almost, not free settling, execute convenience, be suitable for spraying, pellet is even, but must prevent the phenomenon of pellet and solvent-swollen layering;
3rd class skid-resistant coating is without slipproofing agent pellet, mainly the binder resin of coating is carried out molecular designing, and high reactivity group constituents 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 the service requirements meeting ship deck, mainly there is 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 not good enough; Cold-and-heat resistent is alternately poor etc.In modern industry and daily life, various corrosion is seen everywhere, and especially in ocean, engineer equipment is in humidity, high salt, windy, blast air environment, for extreme environment, exposed parts are easily subject to serious corrosion, and its work-ing life is reduced, 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.
Summary of the invention
