Embodiment approach

[0019] According to a preferred embodiment of the present invention, the solid content of the oil-based protective coating composition is 83-95% by weight, and the pH is 6.5-9.5. Preferably, the oil-based protective coating composition is weakly alkaline, which is more conducive to forming a uniform high-temperature anti-sticking protective film layer on the surface of the rolling equipment, and at the same time the film layer will be rapidly cured at room temperature; The solid content of the composition is preferably 87-95% by weight, which can prevent the surface film layer from flowing, so that the coating has good adhesion, and the coating adhesion can meet the requirements of the titanium ingot roller table vibrator whether it is wet film or dry film. The need for friction, there will be no coating peeling or powder. Further preferably, the solid content of the oil-based protective coating composition is 90-95 wt %, and the pH is 7.7-9.2; more preferably, the solid conte...

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 2g Fe 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 solid content of the oily protective coating composition A1 was determined to be 95%, and the pH value was 8.3.

[0044] The oily ...

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 4g Fe 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 8.4.

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

Abstract

The invention relates to the field of coatings, and discloses an oil protective coating composition as well as application thereof, and a production method of titanium tubes. By utilizing the total weight of the oil protective coating composition as 100 parts by weight, the oil protective coating composition comprises 5-15 parts by weight of oil film former, 40-45 parts by weight of Al powder, 0-1 part by weight of Fe powder and 40-50 parts by weight of Al2O3 powder. The oil protective coating composition does not contain harmful elements restrained in RoHS quality; besides, when the oil protective coating composition is applied to production of the titanium tubes, the production process is simple and is easy to operate, and the oil protective coating composition can be on-line used on a production line equipped with pneumatic spraying, vacuum spraying or brush coating equipment.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an oil-based protective coating composition, the application of the coating composition in the production of titanium pipes, and the production method of the titanium pipes. Background technique [0002] At present, in the process of producing the titanium tube using the existing technology, the titanium ingot is kept in a 900° C. heating furnace for 4 hours, and then pushed out of the heating furnace to roll the titanium tube. Since the titanium-based titanium alloy is kept at a high temperature of 900 °C for 4 hours, when rolling the titanium tube, it will "stick to titanium" with the steel rolling equipment, roller table and rolling capstan, which makes the surface of the rolled titanium tube different. The phenomenon of deep "meat deficiency" is due to the rotating piercing and rolling when rolling the titanium tube, and the titanium billet is pierced and rolled during high-speed rota...
