| titleOfInvention | High-temperature-resistant stainless steel seamless steel tube and surface treatment process thereof |
| abstract | The application relates to a high-temperature-resistant stainless steel seamless steel tube and a surface treatment process thereof, wherein the surface of the high-temperature-resistant stainless steel seamless steel tube is coated with a surface treatment agent, and the surface treatment agent comprises the following components in parts by weight: 40-50 parts of polytetrafluoroethylene; 8-10 parts of benzophenone hydrazone; 1-2 parts of an initiator; 12-15 parts of bismaleimide resin; 8-12 parts of alpha-cyanoacrylate; 10-14 parts of a diluent; 3-4 parts of floating beads; the surface treatment process of the high-temperature resistant stainless steel seamless steel pipe comprises the steps of preparing and treating a surface treatment agent to obtain a finished steel pipe. The application has the following advantages and effects: rigid benzene ring groups are introduced by copolymerization of polytetrafluoroethylene and benzophenone hydrazone to obtain a copolymer with good heat resistance, and then the copolymer reacts with bismaleimide resin to form a cross-linked network so as to enhance the high temperature resistance of a coating of the surface treating agent; the diluent and the alpha-ethyl cyanoacrylate are mixed and further mixed with the spherical floating beads to form a continuous space network, so that the high temperature resistance of the steel pipe is improved. |
