Example Embodiment

[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 adopted, as long as the components are uniformly mixed, and can be used and prepared immediately. However, the inventor of the present invention found in research that the following method is used to prepare oily high temperature resistant anti-sticking titanium coating, which can make the components mix more uniformly. The specific method is: first mix the oily film-forming agent and the diluent to dilute, then slowly add tin powder, iron oxide powder and aluminum oxide powder under stirring, then add the curing agent, stir evenly, and then add Dispersant, stir until it is uniform and stable.

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

[0039] Under normal temperature and pressure, weigh the epoxy resin (50% solid content) and place it in a container, set aside; add diluent, stir evenly and set aside; measure Sn powder and Fe 2 O 3 Powder, Al 2 O 3 Add powder to the container slowly, keep stirring during the adding process, and stir evenly; then measure the curing agent SiO 2 Add the powder to the container and stir evenly; then add the dispersant polyvinyl alcohol 200 to the container and stir until the solution is in a uniform and stable phase to obtain the oily high temperature resistant anti-sticking titanium paint of the present invention. The amount of each raw material will be shown in Table 1.

[0047] After coating the coatings of the examples and comparative examples on the surface of steel equipment, rolls or winches by air pressure spraying, vacuum spraying or manual brushing, they were naturally dried and cured at room temperature for 5-10 minutes to obtain a thickness of 0.2- 0.4mm film layer. The titanium tube rolling was performed at 900°C. See Table 3 for specific bonding conditions.

Abstract

The invention relates to an oil-based high-temperature-resistant anti-bonding titanium coating and application thereof and belongs to the technical field of titanium-steel anti-bonding coatings. The oil-based high-temperature-resistant anti-bonding titanium coating is used in titanium tube rolling. The coating is prepared from, by weight, 50-150 parts of oil-based film-forming agent, 30-80 parts of tin powder, 250-350 parts of iron sesquioxide powder and 400-450 parts of aluminum oxide powder. Steel equipment, roller beds and winches are coated with the oil-based high-temperature-resistant anti-bonding titanium coating, a very good isolation layer is formed, it can be guaranteed that a titanium ingot and steel equipment rollers or the winches are not subjected to a bonding reaction in the rolling or piercing process at the temperature of 900 DEG C, the precision size and surface quality of the product are improved, the yield of titanium material machining is increased, the production efficiency of titanium material machining is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to an oily high temperature resistant anti-adhesion titanium coating and its application, belonging 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 a...
