Problems solved by technology

[0004] In the rolling process of titanium tubes, due to the deformation of titanium ingots, the effect of spraying the coating on the surface of titanium ingots to prevent titanium-steel bonding is not good
If the paint is directly sprayed on the surface of the rolling capstan, due to the different materials of the capstan and the titanium ingot, the film forming and adhesion effects are poor, and it cannot prevent titanium-steel bonding well
In addition, the use of this coating requires spraying treatment on the surface of each titanium ingot, and the coating needs a certain period of time to dry after spraying, so the preparation process becomes complicated, the preparation time is long, and continuous and efficient production is not possible.

preparation example Construction

[0031] The preparation method of the oily high temperature resistant anti-sticking titanium coating of the present invention has no special requirements, and various methods commonly used in the field can be used, as long as the components are mixed evenly, and it can be prepared immediately for use. However, the inventors of the present invention found in their research that the following method is used to prepare the oil-based high-temperature anti-sticking titanium coating, which can make the components mix more uniformly. The specific method is: first mix the oily film-forming agent with the diluent to dilute, then slowly add zinc powder, ferric oxide powder and aluminum oxide powder under stirring, then add the curing agent, stir evenly, and then add Dispersant, just stir until it becomes a uniform and stable phase.

[0032] The oily high temperature resistant anti-sticking titanium coating of the present invention can be used in high temperature rolled titanium pipes.

[0039] Under normal temperature and pressure, take epoxy resin (solid part content 50%) and place in container, stand-by; Add diluent, stand-by after stirring evenly; Measure Zn powder, Fe 2 o 3 Powder, Al 2 o 3 powder, slowly add to the container, stirring continuously during the adding process, and stir evenly; then measure the curing agent SiO 2 powder, put it into a container, and stir evenly; then measure and add polyvinyl alcohol 200 as a dispersant, add it into the container, and stir until the solution is in a uniform and stable phase, and the oily high-temperature-resistant anti-sticking titanium coating of the present invention is obtained. The consumption of each raw material is shown in Table 1.

Abstract

The invention relates to an oily high-temperature-resisting bonding prevention titanium coating and application thereof, belongs to the technical field of titanium-steel bonding prevention coatings and aims at providing an oily high-temperature-resisting bonding prevention titanium coating used in titanium tube rolling. The coating is prepared from, by weight, 50-150 parts of an oily film-forming agent, 0-50 parts of zinc powder, 250-350 parts of ferric oxide and 400-450 parts of aluminum oxide powder. The oily high-temperature-resisting bonding prevention titanium coating is applied to a steel and iron device, a roller or a winch to form a very good isolation layer and can ensure that titanium ingots do not produce bonding reaction with the steel and iron device, the roller or the winch in the 900 DEG C rolling or perforation process, improve the size precision and surface quality of products, improve the machining yield and production efficiency of titanium materials and reduce the production costs.

Description

technical field [0001] The invention relates to an oily high temperature resistant anti-adhesion titanium coating and its application, and belongs to the technical field of titanium-steel anti-adhesion coatings. Background technique [0002] At present, the domestic use of titanium ingot round blanks to produce titanium tubes is to directly heat the titanium ingot round billets in a heating furnace at 900 ° C for more than 4 hours, and then push out the heating furnace for high-temperature rolling of titanium tubes. Due to the high temperature, titanium and titanium alloys tend to "stick to titanium" with steel rolling equipment, roller tables and rolling winches, which makes the surface of titanium tubes appear "lack of meat" at different depths. It is rotating piercing and rolling. The titanium billet is pierced and rolled during high-speed rotation. Due to the high temperature characteristics of the titanium-based titanium alloy, it is easy to stick to iron, and even form...
