Elastomer resin coating crosslinking agent

Elastomer resin coating crosslinking agent,Main use of modified silicone elastomer resin, compared with epoxy series products in maintenance gloss, weatherability, more outstanding. In addition to ensure the compatibility with crosslinking agent, drying, coating adhesion between the film after, again, the strength and elasticity and ease NBR elastomer modified resin.

Parallel and packing of the glass flake resin dispersed and thus improve the abrasion resistance, formation of cavitation occurs strong water pressure isolation, effectively prevent through water, oxygen and other factors.

Related research report, coating metal material film can improve the cavitation erosion resistance. Which occur on the turbine impeller in order to solve the cavitation erosion phenomenon, with use of nanometer composite material (Ti - Si - C - N) form the membrane layer method. Heated Ni - Al thin film deposition in coating, this technology can be applied to improve the cavitation erosion resistance of the coating.

Although the thin-film coating at the metals can significantly improve the cavitation erosion resistance, but once appear cracks, coating surface will immediately appear corrosion phenomenon, in addition to the material compatibility with other material is bad, will encounter problems in production of synthetic.

If make the nanometer metal material deposition, the coating on the surface of the coating film when need to adjust the temperature and pressure, precursors must be formed in the thin film on the surface of the coating, so to be the size of the coating have conditionality, production costs are high and greatly influence the universalization of the products.

So the economical efficiency of the existing method is using the optimal size of the inorganic filler, with coatings, inorganic composite system, to correspond to the requirements of the resistance to abrasion and cavitation erosion.

Only use elastic polymer as main ingredient, water jet produced by cavitation can make local elastic body deformation, and glass flake added, composite manufacturing into a can make water jet pressure, inorganic coating parallel spread out, reduce the overall stress of coating with less elastic deformation increase resistance to the corrosion effect.

The cavitation erosion resistance of product development is a, inorganic composite coating, mainly composed of NBR (Acrylonitrile - butadien rubber) elastic epoxy resin composition, according to the requirement of the cavitation erosion resistance design, the product for the strong impact ability of water jet has good absorption capacity, minimize coating deformation, reduce the fatigue of material surface by cavitation and erosion due to fatigue damage phenomenon.

Moreover internal plate type nanoscale inorganic glass flake resin filler for external shock ability to absorb the second time, the maximum possible improve the abrasion resistance.

The composite coating thickness of plate type packing is 0.1 ~ 0.2, the size of 20 ~ 30, aspect ratio is about 200 ~ 300, the strength and elongation of cross section, through the experiment proved that nano filler for abrasion resistance has significant improvement. Intensity of 4.8 ~ 6 n/above, section elongation rate more than 30%, abrasion under 10 mm 2 / h speed, compound resistance to ageing cycle test all the outstanding performance.

Nanoscale inorganic glass flake filler can improve the mechanical and physical performance, according to the most suitable for the mixing proportion of mixed maintain excellent elasticity ratio, extension and strength, to ensure the best cavitation erosion resistance, the thickness of the nano glass flake is evenly distributed array form of physical isolation, scattered wallop under strong pressure, improve wear resistance.

For the recent large-scale, high speed ship against cavitation has the very good protection effect.
