Abstract

The invention relates to an oily high-temperature-resisting titanium-steel bonding prevention coating and application thereof, belongs to the technical field of titanium-steel bonding prevention coatings and aims at providing an oily high-temperature-resisting titanium-steel bonding prevention 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, 100-150 parts of talcum powder, 200-300 parts of ferric oxide powder and 400-450 parts of aluminum oxide powder. The oily high-temperature-resisting titanium-steel bonding prevention 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-titanium-steel bonding coating and an application thereof, belonging to the technical field of titanium-steel anti-bonding 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 ...

Embodiment 1～5

[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, talcum 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 to the container, and stir until the solution is in a uniform and stable phase to obtain the oily high temperature resistant anti-titanium-steel bonding coating of the present invention. The consumption of each raw material is shown in Table 1.
