The corresponding coating process technology provided with good economic efficiency, social benefit and wide popularization and application foreground are provided.
A specific embodiment of the invention is further described below with reference to embodiment, is not therefore limited the present invention
System is among the embodiment described range.
Embodiment 1
Aqueous anti-steel-titanium bonding coating is prepared according to each raw material in table 1 and its weight proportion:
The aqueous anti-steel of table 1-titanium bonding coating raw material and its proportion
Wherein, K1~K4 is experimental group, and D1~D2 is control group, and a blank control group D3 is separately arranged and (does not apply coating
Direct Rolling), and wherein Watery film-fomer is epoxy resin (solid content 50%)；Curing agent is SiO2, dispersing agent is poly- second
Enol.Aqueous anti-steel prepared by the present invention-titanium bonding coating pH value is 7.5~9.5；Solid content is 85~90%.
Preparation method are as follows: at normal temperatures and pressures, by Watery film-fomer, Cu powder, talcum powder, Al2O3Powder, Fe2O3Powder adds
Enter into container, be stirred continuously in adition process, is stirring evenly and then adding into curing agent, dispersing agent and water, stirs evenly, to solution
Coating is bonded in uniform and stable phase to get aqueous anti-steel-titanium.
Aqueous anti-steel prepared by above-mentioned each group-titanium bonding coating uses pneumatic spraying, airless spraying or manual brushing
Mode carry out be coated in steel equipment surface, roller surface or capstan winch surface after, at room temperature spontaneously dry, solidify 10~
15min obtains the film layer with a thickness of 0.2~0.4mm.Titanium tube rolling is carried out at 900 DEG C.The titanium tube surface matter obtained after rolling
Amount is good, and titanium tube and roll, capstan winch etc. are not adhered, and specific comparative situation is as follows:
The aqueous anti-steel of table 2-titanium bonding coating and control group test performance
From Table 2, it can be seen that using the coating coating equipment of embodiment K1~K4, the titanium tube surface matter that is obtained after rolling
Amount is good, and titanium tube and roll, capstan winch etc. hardly bond.It is not coated by the roll or strand of any coating (i.e. blank control group D3)
Disk, the titanium tube obtained after rolling, titanium tube surface defect is serious, and equipment also has a degree of viscous titanium, ability after needing to polish
It continues to use.Using the coating coating equipment of D1, D2, the titanium tube surface defect rate after rolling is still higher, cannot prevent well
Only titanium steel bonds.
10,000 tons of production capacities are produced in design per year, are calculated with 1.5 tons of each titanium ingot (semifinished product), to be produced 6300 or so titaniums every year
There is titanium steel bonding 5mm~20mm depth calculation with each titanium ingot in billet, and each titanium ingot will machine away 100~200 kilograms, with
80000 yuan/ton of titanium ingot calculating, each titanium ingot lose between 8000~16000 yuan because gluing titanium cutting tip, meanwhile, also to spend
Take a large amount of human and material resources to be cut, it is additional to increase production cost and production time, and use this technology, will for titanium tube and
A large amount of production cost is saved in the production of other titanium alloy products, in terms of in each titanium ingot operation of rolling using 2~5kg of coating
It calculates, every coating price is calculated by 200,000/ton, and the new returns of this technology are seen below shown in formula:
The output of the annual titanium ingot of W-: being calculated with 10,000 tons, about produces 6300 titanium ingots every year；
The each titanium ingot of A- is because gluing titanium-steel layer problem cutting amount: pressing 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: it is calculated by 200 yuan/Kg；
The new returns that Y- uses this technology to generate every year:
Then:
Y=(P1 × A-W1 × P2) × W
=(4000-600) × 6300
=2142 (ten thousand yuan)
As it can be seen that coating provided by the invention is with good economic efficiency, social benefit and wide popularization and application foreground.
