General knowledge of coating: nano composite polyurethane aviation coating and its preparation method and Application

Core tip: the invention relates to nanocomposite polyurethane aviation coating and its preparation method and application The coating is composed of two components, i.e modified synthetic resin and curing agent The modified synthetic resin is composed of 0.2-50% nano slurry, 5-85% synthetic resin, 0-40% pigment, 0-4% auxiliary agent and residual solvent The preparation is to first add nano slurry into synthetic resin solution, then add residual solvent, auxiliary agent and pigment, conduct dispersion grinding, and then make the modified synthetic resin component of nano composite polyurethane aviation coating after filtration, and evenly mix the curing agent and modified synthetic resin to get coating Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water The invention relates to a nano composite polyurethane aviation coating and a preparation method and application thereof The coating is composed of a matched modified synthetic resin and a curing agent The modified synthetic resin is composed of 0.2~50% nano pulp, 5~85% synthetic resin, 0~40% pigment, 0~4% auxiliary agent and residual solvent The preparation is to first add nano slurry into synthetic resin solution, then add residual solvent, auxiliary agent and pigment, conduct dispersion grinding, and then make the modified synthetic resin component of nano composite polyurethane aviation coating after filtration, and evenly mix the curing agent and modified synthetic resin to obtain the coating; the application is to spray antirust primer first, and then spray the coating The nano composite polyurethane aviation material is prepared by the method of nano slurry, which makes the nano powder material disperse and stable in the coating, and improves the color retention and light retention of the coating The coating system composed of the nano composite polyurethane coating and the matching primer has excellent weather resistance and corrosion resistance Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
