Description
Technical field
The invention belongs to technical field of coatings, and in particular to a kind of coating for the protection of liquid gasification tank.
Background technology
Modern society to Some Petrochemical Byproducts and the remaining raffinate of liquefied petroleum gas in order to make full use of, typically with raffinate
For raw material, combustion gas is made in raffinate., it is necessary to gasify to raw material liq in gas-making process.And then liquid gasification can be used
Tank equipment, and the tank body of liquid gasification tank is typically to be made up of steel, in order to lift its surface quality in atmospheric environment, is needed
Preservative treatment is carried out to it.Common is exactly that one layer of protective coating is coated on its surface, and the effect of protective treatment and coating
Quality it is closely bound up.The integrated quality of presently commercially available most coating is bad, causes the tank body of liquid gasification tank often to occur
The bad phenomenons such as corrosion, abrasion, it have impact on its outward appearance condition and using quality, it is necessary to constantly be improved.
The content of the invention
The purpose of the present invention is to be directed to the problem of existing, there is provided a kind of coating for the protection of liquid gasification tank.
The present invention is achieved by the following technical solutions：
A kind of coating for the protection of liquid gasification tank, it is made up of the material of following parts by weight：
65 ~ 70 parts of styrene resins, 33 ~ 36 parts of Isooctyl acrylate monomers, 12 ~ 16 parts of terpene resins, 7 ~ 9 parts of phenolic resin, 5 ~ 8 parts
Methylcellulose, 4 ~ 6 parts of triethyl borates, 3 ~ 5 parts of GDMAs, 1 ~ 3 part of konjac glucomannan, 10 ~ 14 parts of modifications
Mica powder, 4 ~ 7 parts of glycerine.
Preferably, it is made up of the material of following parts by weight：
68 parts of styrene resins, 35 parts of Isooctyl acrylate monomers, 14 parts of terpene resins, 8 parts of phenolic resin, 7 parts of methylcellulose, 5
Part triethyl borate, 4 parts of GDMAs, 2 parts of konjac glucomannans, 12 parts of modified micaceous powder, 6 parts of glycerine.
Further, the preparation method of the modified micaceous powder comprises the following steps：
（1）Mica powder is first put into progress heating and calcining processing in heating furnace, it is 700 ~ 760 first to control the temperature in heating furnace
DEG C, the temperature in heating furnace is risen to 920 ~ 980 DEG C again after handling 35 ~ 40min, taken out after handling 45 ~ 50min, then by cloud
Female powder is put into 30 ~ 35min of immersion treatment in phosphoric acid solution, with standby after deionized water rinsing one time after taking-up；
（2）By step（1）Mica powder after processing, which is put into drying box, carries out primary drying processing, takes out, connects after 1 ~ 1.5h
And be put into solution A, while constantly carry out ultrasonication, filter out mica powder after 40 ~ 45min, finally again by mica powder
It is put into drying box and carries out redrying processing, is taken out after 1 ~ 2h；The solution A by following parts by weight material group
Into：16 ~ 20 parts of nano zirconium dioxides, 13 ~ 15 parts of titanate coupling agents, 2 ~ 5 parts of vaseline, 4 ~ 7 parts of methyl methacrylates,
350 ~ 380 parts of water.
Further, step（1）Described in phosphoric acid solution mass fraction be 8 ~ 11%.
Further, step（2）Described in primary drying processing when control temperature in drying box be 75 ~ 80 DEG C.
Further, step（2）Described in the frequency of ultrasonication be 88 ~ 92kHz.
Further, step（2）Described in redrying processing when control temperature in drying box be 85 ~ 90 DEG C.
The present invention has carried out special collocation to the component of coating and adjusted, and improves its synthesis well and uses quality.Its
In using styrene resin, Isooctyl acrylate monomer as main film forming matrix composition, then compounding with the addition of terpene resin, phenolic aldehyde tree
Fat, effectively improve overall waterproof, Anticorrosive Character, also added methylcellulose, konjac glucomannan come adjust overall viscosity and
Spreading property, promotes its more preferable film forming, and the triethyl borate of addition, GDMA composition are to film forming base
Body composition has carried out chain modified, enhances the complexity and intensity of cross-linked network, and it is special to improve overall wear-resisting, hardness, attachment
Property；In addition the modified micaceous powder filler composition of formulated is also added, it is to be modified to form as bulk composition using mica powder, first
Calcination processing has been carried out to mica powder, has improved its specific surface area and characterization of adsorption, has then carried out acid soak processing, has been removed
Impurity, and the reactivity on surface is improved, channel design has been dredged, has been laid a good foundation for follow-up processing, afterwards with only
The solution A matched somebody with somebody carries out immersion modification, by nano zirconium dioxide introduce it is intercalated grafted be fixed in mica powder, improve filler
Intensity, the rotproofness of entirety, while again because of the lamellar structure of mica powder so that filler has having good wearability again.
The present invention has advantages below compared with prior art：
Improvement is optimized to the component of coating in the present invention, under the common mating reaction of each composition, painting produced by the present invention
Material has the characteristics such as good wear-resisting, corrosion resistant, heatproof, intensity, and the coating uniform formed, compactness are high, and protective capacities is strong, makes
With long lifespan, and it is not easily cracked and comes off, great popularizing value.

Outer method and step all same.
Control group
Existing commercially available common coating.
In order to contrast effect of the present invention, to above-described embodiment 2, comparative example 1, comparative example 2, comparative example 3,
Coating made from control group carries out performance test, and specific correction data is as shown in table 1 below：
Table 1
| Alkaline-resisting duration（h） | Acidproof duration（h） | Interface bond strength between paint coatings and metallic matrix（MPa） | |
| Embodiment 2 | 2440 | 2050 | 37.6 |
| Comparative example 1 | 1980 | 1760 | 34.4 |
| Comparative example 2 | 2060 | 1820 | 32.8 |
| Comparative example 3 | 1870 | 1610 | 29.3 |
| Control group | 1780 | 1520 | 27.8 |
Note：Alkaline-resisting duration described in upper table 1 refers to the sodium hydroxide solution immersion treatment that mass fraction is 6%, keeping temperature
For 35 DEG C, the unconverted duration of coating paint film is observed, its alkaline-resisting characteristic is contrasted with this；Described acidproof duration refers to use matter
The sulfuric acid solution immersion treatment that fraction is 6% is measured, keeping temperature is 35 DEG C, the unconverted duration of coating paint film is observed, with this
Contrast its acid-resistant property.
Coating integrated quality is good made from the inventive method it can be seen from upper table 1, and protection effect is strong, has good
Economic benefit and application value.
