2017-3-21 23:48:58
Anticorrosive coating with crosslinking agent,Coating is composed of mixed in resin paint and functional additives. In building, automobile, shipbuilding, machinery, industrial coating with more than 2000 varieties, applicable in a wide range of industries.
Due to the production of paints, surface modification, the control property to develop high value-added products. Such as adding aluminium alloy, thus improve the anti-corrosion performance, adding copper powder in the anticorrosion coating, adding silicon the durability of the coating, wear resistance, corrosion resistance, as well as add zinc powder to improve coating anticorrosion performance, etc.
Recently as nanotechnology (Nano technology), the development of Nano sex packing by more and more applied to develop the special coating of electrical conductivity, heat resistance.
In addition to the size of the packing has influence on physical performance, its shape also has a great influence, powder type, fiber type, plate type such as different forms of packing determine the performance and price of products.
Cavitation erosion is refers to the ship, mechanical device, such as due to certain cavitation abrasion and corrosion on the surface of the material. Such as carbon steel material and related material of hydraulic structure due to cavitation surface damage, destruction, so as to accelerate the corrosion at the same time.
Cavitation erosion resistant coatings used in ships, pump, Marine structures, large machinery and equipment, and other part or in whole on the market on a large scale industrial chain is the functional coating of ship class market. Especially since the recent large, of a ship, sailing speed increase, screw the trend of bigness, propeller load increase, high-speed propeller wake pressure drops and produce cavitation.
In order to prevent this kind of phenomenon and the transformation building form, the trial anticorrosive coatings or the analysis of the experimental data, but there is still no fundamental way to solve the corrosion problem.
Characteristics of cavitation erosion resistant coating is extremely strong wear resistance, thus requiring high elastic resin to absorb after formation on the surface of water jet impact energy, the surface of the polymer base from add hybrid inorganic reinforcement material to withstand the impact and improve the wear resistance and durability.
As with inorganic filler in combination with elastic resin and commercialization. With nano inorganic whisker filtering, surface modification of nano filler and produce polymer nano composite, and dispersed in the resin to enhance the durability and corrosion resistance, high inorganic kind of silicate inorganic filler use corrosion resistant coating and the import of glass powder coating of the ship.
Recently, carbon nanotubes, nano graphite and graphene, such as montmorillonite nano-scale application and improve the wear resistance of the product packing were developed.
Chinese name: Diethyl toluene diamine(DETDA)
Physical and chemical properties: light yellow transparent liquid, slightly soluble in water, soluble in alcohols, ethers, ketones and other polar organic solvents, and polyether, polyester polyol compatibility.
Density 1.022
Viscosity (20 ℃) ??mPa·ss290±10
Pour Point ℃-9
Boiling point of310°C
Flash Point°C161.1°C
High elasticity in NBR (Acrylonitrile - butadiene rubber) modified resin add thin film glass flake manufacturing of high-performance heavy-duty coating resistant to cavitation erosion. In order to prevent coating forming after cracking and to improve the wear resistance, the thickness of the glass flake is optimized in the resin.
Development of products for the thickness of glass flake filler 100 ~ 200 nm, the best aspect ratio is 200 ~ 300. The pressure of water jet in the water conditions will make the thickness of the micro change resin and glass flake interface to hae an increased risk of fracture.
Due to the thickness of the nano filler moment rigid relatively small stress reduction in the interface, reduce the possibility of interface fracture. In this study, therefore, can avoid coating interfacial fracture phenomenon, only the best to improve wear resistance of the glass flake size (thickness and length), evenly dispersed in the resin flake filler array corresponding external factors to improve the wear resistance and other functions.
Contains the experiment according to the ceramic, metal, resin series, waterproof, corrosion protective coating agent "- KSF 4929," plastic, the characteristics of standard test method for ASTM D638 extension strength, elongation, etc to develop physical properties test evaluation of the products.
Test results, the intensity is more than 4.8 ~ 6 n /, elongation at break of more than 30%, corrosion wear rate under 10 mm/h 2, composite cycle all aging test results.
