Embodiment approach

[0019] According to a preferred embodiment of the present invention, the solid content of the oily protective coating composition is 83-95% by weight, and the pH is 6.5-9.5. At this time, the oily protective coating composition is weakly alkaline, which is more conducive to the formation of a uniform high-temperature anti-adhesion protective film layer on the surface of rolling equipment, and the film layer can be quickly cured at room temperature; and, the oily protective coating The solid content of the coating composition is preferably 87-95% by weight, which can prevent the surface film layer from flowing and make the coating adhesion good. No matter in wet film or dry film, the coating adhesion can meet the requirements of titanium ingot roller table vibration. The need for machine friction, there will be no peeling or powdering of the coating. Further preferably, the solid content of the oily protective coating composition is 90-95% by weight, and the pH is 7.7-9.2; more...

Embodiment 1

[0037] This embodiment is used to illustrate the production method of the oil-based protective coating composition and titanium tube of the present invention.

[0038] (1) At normal temperature and pressure (25°C, 0.1MPa), weigh 100g of oily epoxy resin (purchased from Nantong Xingchen Synthetic Materials Co., Ltd., with a solid content of 50%, the same below) and place it in a container;

[0039] (2) Add 5g of acetone and stir evenly;

[0040] (3) Weigh 410g Al powder and 40g Sn powder, 440g Al 2 o 3 Powder, under stirring, slowly add to the container, stir evenly;

[0041] (4) Weigh 1g of curing agent SiO 2 powder, add to the container, stir well;

[0042] (5) Weigh 0.5 g of dispersant polyvinyl alcohol into a container, and stir to make the solution in a uniform and stable phase to obtain oily protective coating composition A1.

[0043] The measured solid content of the oily protective coating composition A1 was 95%, and the pH value was 8.4.

[0044] The oily protect...

Embodiment 2

[0046] This embodiment is used to illustrate the production method of the oil-based protective coating composition and titanium tube of the present invention.

[0047] (1) At normal temperature and pressure (25°C, 0.1MPa), weigh 120g of oily epoxy resin (50% solid content) and place it in a container;

[0048] (2) Add 1g of acetone and stir evenly;

[0049] (3) Weigh 440g Al powder and 10g Sn powder, 420g Al 2 o 3 Powder, under stirring, slowly add to the container, stir evenly;

[0050] (4) Weigh 2g curing agent SiO 2 powder, add to the container, stir well;

[0051] (5) Weigh 1 g of the dispersant polyvinyl alcohol into a container, and stir to make the solution in a uniform and stable phase to obtain the oily protective coating composition A2.

[0052] The solid content of the oil-based protective coating composition A2 was determined to be 93%, and the pH value was 8.5.

[0053] The oily protective coating composition A2 is sprayed on the capstan surface with an auto...

Abstract

The invention relates to the field of coatings, and discloses an oily protective coating composition and an application thereof and a production method of a titanium pipe. The oily protective coating composition comprises 100 parts of components by weight: 5 to 15 parts of oily filming agent, 40 to 45 parts of Al (aluminum) powder, 0 to 5 parts of Sn (stannum) powder and 40 to 45 parts of Al2O3 (aluminum oxide) powder. The oily protective coating composition has the advantages that the harmful elements in restriction of RoHS (restriction of hazardous substances) quality are not contained; when the oily protective coating composition is applied into the production of titanium pipes, the production technology is simple, the operation is easy, and the oily protective coating composition can be applied to production lines of air pressure spraying, vacuum spraying or brushing equipment on line.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an oily protective coating composition, the application of the coating composition in the production of titanium tubes, and a production method for titanium tubes. Background technique [0002] At present, the existing technology is used in the process of producing titanium tubes. After the titanium ingots are kept in a heating furnace at 900 ° C for 4 hours, they are pushed out of the heating furnace to carry out the work of rolling titanium tubes. Since the titanium-based titanium alloy is kept at a high temperature of 900°C for 4 hours, it will "stick to titanium" with the steel rolling equipment, roller table and rolling capstan when rolling the titanium tube, which makes the surface of the rolled titanium tube appear different. The deep "lack of meat" phenomenon is due to the rotating piercing and rolling when the titanium tube is rolled, and the titanium billet is pierced and rolled...
