Description
Technical field
The invention discloses a kind of preparation method of corrosion-resistant coating hole sealing agent, belong to coating sealing material technology of preparing
Field.
Background technology
Plasma spray technology occupies critical role in process for modifying surface.By in material surface applying coating, Ke Yiyou
Play a part of to effect protecting matrix, anti-corrosion.But hot-spraying coating is not very fine and close, many holes be present.Work as painting
When layer is used for wear-resisting, a certain amount of hole can be used for preserving lubricant in coating, favourable to antifriction, but be used for anti-corrosion coating,
Corrosive medium will penetrate into substrate surface, and at this moment hole is harmful, it should is reduced or eliminated as far as possible.
To prevent erosion of the corrosive medium to matrix, improve the decay resistance of coating and expand it in particular circumstances
Application, it is necessary to which sealing pores are carried out to coating.Hole sealing technology is that hole sealing agent is coated and penetrated into hot-spraying coating, and then
Realize the sealing pores to hot-spraying coating.
People expand to the hole sealing technology of hot-spraying coating and are extensively studied at present, with the material of making coatings sealing of hole
A lot, machine and inorganic two major classes hole sealing agent are mainly included.Such as number of patent application CN201210516219.8, disclose " a kind of
New hot-spraying coating special inorganic hole sealing agent and its production and use ", it uses the metals such as silicon, aluminium, boron, sodium to aoxidize
Inorganic sealing hole agent is made in the technique such as thing, heated, water quenching, ball milling.And for example number of patent application CN200610030687.9 is disclosed
" a kind of hot spraying coating sealing reagent and its application method ", the hole sealing agent is made up of epoxy resin and curing agent, coated on heat
It spray-on coating surface, can be fully infiltrated into coating porosity, after cured, the hot-spraying coating production that sealing of hole works well can be obtained
Product.However, though existing coating sealing reagent, with good sealing of hole effect, hole sealing agent corrosion resistance is still not satisfactory,
Easily occur foaming, obscission under corrosive environment, ultimately result in matrix and suffer erosion, influence matrix service life.
In summary, in the prior art, to having become everybody by using hole sealing agent to improve hot-spraying coating performance
Generally acknowledged technology trends.But the problem of hole sealing agent corrosion-resistant is not resolved, it would therefore be highly desirable to develop a kind of sealing of hole effect
Fruit is good, excellent corrosion resistance, effectively matrix can be protected not weather, so as to extend the production of the coating sealing reagent of matrix service life
Product.

Powder and 3~5 parts of sodium tripolyphosphates are placed in beaker, are stirred simultaneously heating water bath, are obtained modification liquid；
（3）Count in parts by weight, weigh 45~50 parts of obsidians, 25~30 parts of pitchstones and 15~20 parts of perlite mixing respectively
Ball milling, sieve to obtain mixing and ball milling powder, in mass ratio 1:5, mixing and ball milling powder is placed in modification liquid, ultrasonic disperse, water-bath
Heat and be stirred, standing is cooled to room temperature, filters to obtain filter residue, washing, dry modified filler；
（4）Count in parts by weight, respectively weigh 45~50 parts of methyl methacrylates, 10~15 parts of butyl acrylates, 2~3 parts
Benzoyl peroxide and 25~30 parts of acrylic acid are stirred to obtain dropping liquid；
（5）In mass ratio 1：5, modified filler is mixed with n-butanol and is placed in four-hole boiling flask, then at 100~110 DEG C
Dropping liquid is added dropwise in four-hole boiling flask, after being added dropwise to complete, insulation reaction and stand be cooled to 70 DEG C, be evaporated under reduced pressure and adjust
PH to 7.0, standing are cooled to room temperature, you can are prepared into a kind of corrosion-resistant coating hole sealing agent.
Step（1）Described sodium carbonate liquor drop rate is 2mL/min, and dripping quantity is the 10% of mixed liquor quality.
Step（5）Described dropping liquid time for adding is 100~120min.
Step（5）Described regulation pH is using triethylamine.
The beneficial effects of the invention are as follows：
（1）The present invention is used as the matrix of modified filler by inorganic matters such as obsidian, pitchstones, because the materials such as obsidian have
Expansion character, when resin solidification heat release, inorganic filler is heated to be expanded, and the micropore of coating surface is effectively filled out
Fill, while close material pore structure, the porosity of coating is significantly reduced, so as to shield or slow down external corrosive medium pair
The osmosis of coating and matrix, plays a very good protection to coating, increases the service life；
（2）The inorganic material that the present invention is filled by aluminum phosphate coating modification, inorganic filler is dispersed to inside resin and permeate
, i.e. can oxygen loss solidification, hair after it is penetrated into hole because acrylic resin is in atmosphere liquid phase to coating material
Stiffization, it is brilliant to material hole to carry out effective sealing of hole, and its surface roughness of coating reduces after sealing of hole, hardness increases, its is resistance to
The corrosive power of acid, alkali and salt greatly enhances, and effectively extend coating uses duration.
