Wherein, K1～K5 is experimental group, D1～D2 is matched group, separately arranges blank group D3 and (is not the most coated with coating
Direct Rolling), and wherein Watery film-fomer is epoxy resin (solid content is 50%)；Firming agent is SiO2, dispersant is poly-second
Enol.Aqueous high-temperature-resistant isolation titanium-steel coating pH value prepared by the present invention is 7.5～9.5；Solid content is 85～90%.
Its preparation method is: at normal temperatures and pressures, by Watery film-fomer, Zn powder, Fe powder, Al2O3Powder, joins in container,
Adition process is stirred continuously, is stirring evenly and then adding into firming agent, dispersant and water, stirs, treat that solution is uniform and stable
Phase, obtains aqueous high-temperature-resistant isolation titanium-steel coating.
The aqueous high-temperature-resistant isolation titanium-steel coating prepared above-mentioned each group uses pneumatic spraying, airless spraying or craft
The mode brushed is coated behind steel equipment surface, roller surface or capstan winch surface, at room temperature natural drying, solidification
10～15min, obtain the film layer that thickness is 0.2～0.4mm.Titanium pipe rolling is carried out at 900 DEG C.The titanium pipe table obtained after rolling
Face quality is good, and titanium pipe is not adhered with roll, capstan winch etc., and concrete contrast situation is as follows:
Table 2 aqueous high-temperature-resistant isolation titanium-steel coating and matched group test performance
From Table 2, it can be seen that use embodiment K1～the coating coating equipment of K5, the titanium tube-surface matter obtained after rolling
Amount is good, and titanium pipe bonds hardly with roll, capstan winch etc..It is not coated by roll or the strand of any coating (i.e. blank group D3)
Dish, the titanium pipe obtained after rolling, titanium tube-surface defect is serious, and equipment also has a certain degree of viscous titanium, needs ability after polishing
It is continuing with.Using the coating coating equipment of D1, D2, the titanium tube-surface ratio of defects after rolling remains unchanged higher, it is impossible to well prevent
Only titanium steel bonding.
10,000 tons of production capacities are produced in design per year, with the 1.5 tons of calculating of each titanium ingot (semifinished product), to produce the titanium of about 6300 every year
, there is titanium steel bonding 5mm～20mm depth calculation with each titanium ingot in billet, and each titanium ingot to machine away 100～200 kilograms, with
The calculating of 80000 yuan/ton of titanium ingot, each titanium ingot is lost between 8000～16000 yuan because of viscous titanium cutting tip, also to spend meanwhile
Take substantial amounts of human and material resources to cut, extra increase production cost and production time, and use this technology, will for titanium pipe and
Substantial amounts of production cost is saved in the production of other titanium alloy products, to use in terms of coating 2～5kg in each titanium ingot operation of rolling
Calculating, every coating price is calculated by 200,000/ton, and the new returns of this technology see below shown in formula:
The volume of production of W-annual titanium ingot: with 10,000 tons of calculating, produces 6300 titanium ingots the most every year；
A-each titanium ingot is because of the amount of viscous titanium-steel layer problem cutting: by 50Kg calculating/titanium ingot；
The cost of P1-titanium ingot: 80 yuan/Kg；
W1-sprays the consumption of high temperature resistant anti-stick coating, 3Kg/ ingot；
P2-high temperature resistant anti-stick coating price per ton: calculate by 200 yuan/Kg；
Y-uses the new returns that this technology produces every year:
Then:
Y=(P1 × A-W1 × P2) × W
=(4000-600) × 6300
=2142 (ten thousand yuan)
Visible, the coating that the present invention provides has good economic benefit, social benefit and wide popularizing application prospect.
