Anti-corrosion water-based polyurethane coating crosslinking agent
Polyurethane coating has excellent cold resistance, abrasion resistance and corrosion resistance performance, but the WPU molecules containing a hydrophilic group, so the poor water resistance, solvent resistance, corrosion resistance and other performance.
For this reason, people on the polyurethane molecular main chain or side chain to introduce epoxy resin, acrylic ester, organic silicon and other network functional organic compound preparation into the polymer, or added in the WPU nanoparticles, in order to improve the corrosion resistance and other properties of WPU.
Epoxy resin modified water-based polyurethane anti-corrosive coating. The modification of WPU with epoxy resin can give a good corrosion resistance to water-based polyurethane.
Wang chunyan and other products are made from epoxy resin modified water-based polyurethane, and the rich zinc coating with excellent environmental protection and excellent corrosion resistance. The results showed that the corrosion resistance of water-based epoxy polyurethane coating was stronger than that of traditional epoxy. The addition of zinc powder has a certain effect on the corrosion resistance of the coating, and adding a small amount of aluminum powder can improve the corrosion resistance of the coating.
The coating has excellent corrosion resistance, high mechanical strength, convenient construction, and has broad application prospect in iron and steel.
Sun daoxing and other people will gather the epoxy resin e-44 with silicone polyurethane resin and make a water-based polyurethane epoxy resin.
The results showed that the overall performance of epoxy resin was optimal when it was 30% of the mass fraction in resin. Titanium iron powder and zinc phosphate nontoxic anticorrosive pigments can be prepared has good anti-rust effect of environmental anticorrosive coating, titanium and iron powder dosage was 5% can make the anticorrosive coating anticorrosion performance and mechanical performance at optimum levels.
Epoxy acrylic resin composite modified water-based polyurethane anti-corrosive coating. Acrylic resin has good water resistance and weatherability. Use of waterborne polyurethane modified acrylic resin, can make the pu high wear resistance and good mechanical properties and acrylic good weathering resistance and water resistance of both organically, so as to increase the performance of the WPU coating obviously improved. Epoxy and acrylic combined modified water-based polyurethane can be combined with the advantages of high performance WPU anti-corrosion coatings.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine packing： net weight 200KG/ galvanized iron drum (a small cabinet pallet loaded 16 tons), 1000KG/IB barrels (a small cabinet loaded 18 tons or 23 tons of ISOTANK).
In situ polymerization of water-based polyurethane - epoxy - acrylic (WPUEA) compound emulsion was prepared by wu.
The experimental results show that when the molar ratio of - NCO/OH for 12 ~ 15, TMP dosage is 2% ~ 3%, E20 dosage is 4% ~ 4%, DMPA dosage is 6% ~ 9%, MMA dosage was 20% ~ 30%, emulsion storage period more than 10 months, freezing and thawing cycle is more than 5 times, rocker hardness of coating film is greater than 0.70, the tensile strength is greater than 10 mpa, water resistance, acid and alkali, solvent resistance and anticorrosion performance than unmodified WPU coatings have improved significantly.
Organic silicon modified water-based polyurethane anti-corrosive coating. Organic silicon coating has excellent heat resistance, weather resistance, hydrophobic, and polyurethane coating has outstanding abrasion resistance, oil resistance and good weldability, heat resistance, water resistance, corrosion resistance is not ideal. Therefore, the use of silicone modified polyurethane materials can make up for the deficiency of polyurethane materials.
PathakSS using sol-gel technology, such as silane (MTMS) with methyl 3 armour oxygen radicals and gamma (2.3 -) epoxy propyl oxygen radicals propyl silane three oxygen radicals (GPTMS) modified waterborne polyurethane, used for protection of aluminium and aluminium alloy was prepared by organic silicone polyurethane coating.
Results show that the addition of organic silicon waterborne polyurethane coating enhances the corrosion resistance, flexibility and mechanical stress, thermal degradation temperature of the coating increased to about 206 ℃, thermal stability is improved greatly. This high performance heat-resistant coating is suitable for aerospace, Marine, automobile and other fields.
