Description
Technical field
The present invention relates to coating manufacturing technology field, and in particular to a kind of special reversible temperature indicating light of transformer pile head is stable to be applied
Material and preparation method thereof.
Background technology
Power transformer is the important electric equipment in supply network, and the quality of its performance can directly affect electric service water
Flat, transformer plays the vital task of energy conversion and conveying in power system, and power transformer is exposed to the weather for a long time, gesture
The oxidation and weathering of transformer pile head coating must be caused, Paint Falling is effectively caused, serious consequence may will be caused.
Thermo-color is a kind of new sapecial coating, it be with color or outward appearance phenomenon come indicator body surface temperature and
A kind of coating of Temperature Distribution, indicates that temperature has the advantages that with thermo-color measurement simple, fast and easy, directly perceived, is general
Glass-stem thermometer, thermocouple, less than thermal resistance thermometer.Due to its special use value, so by scientific and technological circle of various countries
Attention, and carried out substantial amounts of research work.The research and application of thermo-color have the history of 50 or six ten years abroad.It is early
Before and after second of Great War, some countries are just studied and produced to thermo-color.
Check that transformer pile head temperature uses infrared measurement of temperature method at present, this method cost of labor is high, and when equipment peace
Dress apart from ground it is higher when, operation maintenance personnel need to ascend a height operation, increase danger.Therefore, transformer can be adapted to by developing one kind
The thermo-color with anti-oxidant and weatherability used also just turns into the task of top priority.
The content of the invention
It is an object of the invention to provide stable coating of the special reversible temperature indicating light of a kind of transformer pile head and preparation method thereof, production
Product have good sun-proof, ageing resistace, can pass through the change of the change indicating transformer pile crown temperature of color, Er Qiewen
Spend pace of change fast, rewarming time is short, meanwhile, preparation method is simple, with low cost.
To achieve these goals, the technical solution adopted by the present invention is as follows：
A kind of stable coating of special reversible temperature indicating light of transformer pile head, including following component and its mass fraction：Component A：
40~75 parts of epoxy resin, 10~30 parts of temperature-sensitive powder, 1~5 part of dispersant, 1~5 part of levelling agent, 1~3 part of defoamer, anti-settling agent
1~5 part, 5~20 parts of solvent, 1~10 part of sericite in powder, 1~5 part of aluminium-magnesium silicate, 1~10 part of ultraviolet absorber；B component：Ring
50~100 parts of oxygen curing agent, 0~50 part of dimethylbenzene；The mass ratio of the component A and B component is 1 ︰ 0.7~1.
According to above scheme, the temperature change interval of the temperature-sensitive powder is 50 DEG C~70 DEG C.
According to above scheme, the solvent is dimethylbenzene.
According to above scheme, the ultraviolet absorber is 2-hydroxy-4-n-octoxybenzophenone.
According to above scheme, the particle diameter of the sericite in powder is 1250 mesh, and the particle diameter of aluminium-magnesium silicate is 5000 mesh.
According to above scheme, the anti-settling agent is organobentonite, absolute ethyl alcohol, the mixture of dimethylbenzene or gas phase dioxy
SiClx, the organobentonite, absolute ethyl alcohol, the mass ratio of dimethylbenzene are the ︰ 15~20 of 1~2 ︰ 1.
A kind of preparation method of the stable coating of special reversible temperature indicating light of transformer pile head, comprises the following steps：
1) stirred after mixing epoxy resin, dispersant, levelling agent, defoamer, anti-settling agent, solvent, progress is pre-dispersed, obtains
Obtain pre-dispersed mixture；
2) temperature-sensitive powder, sericite in powder, ultraviolet absorber, aluminium-magnesium silicate and pre-dispersed mixture are put into grinder in the lump
In, it is ground after adding bead, is ground to fineness and reaches less than 40 μm, component A is obtained after filtering；
3) epoxy hardener and dimethylbenzene are proportionally prepared and are added in container, be uniformly mixing to obtain B component；
4) component A is prepared in proportion with B component, product is made after stirring.
According to above scheme, the step 1) in the rotating speed of stirring be 600r/min, pre-dispersed time is 1-3h.
According to above scheme, the step 2) in grinder rotating speed be more than or equal to 1500r/min, the outlet of grinder
Temperature control is at 40~60 DEG C, and because sand mill is metal bucket, if not controlling outlet temperature, its internal temperature is too high will to be made to disperse
Agent is constantly evaporated, so as to component A will be made slowly to solidify.
Step 1 in the preparation method of the present invention) in the pre-dispersed time be less than 1h, it is epoxy resin, dispersant, levelling agent, anti-
Heavy agent, defoamer, solvent are scattered incomplete, if the pre-dispersed time is more than 3h, will cause temporal waste；Anti-settling agent needs
Addition in 30min has been configured, result of prevention is otherwise influenceed.Step 2) in, if fineness will make to contain in corrosion resistant coating higher than 40 μm
Particulate material.
After the completion of component A is prepared with B component, preferably mixed in 3h and carry out coating decoration.
If the mixture of anti-settling agent organobentonite, absolute ethyl alcohol, dimethylbenzene preparing in 30min, it is necessary to use.
Dispersant is high 750 dispersant of enlightening (Tego Dispers 750W), high 715 dispersant (the Tego Dispers of enlightening
715W), it is any one in high 710 dispersant of enlightening (Tego Dispers 710), EFKA dispersant 4310 (EFKA 4310)
Kind.
High 1484 stream of high 100 levelling agent of levelling agent enlightening (Tego Glide 100), the levelling agents of Bi Ke 333 (BYK-333), enlightening
Flat agent (Tego Glide 1484), Taiwan add up to any one in defoamer and levelling agent D201 (D201).
Defoamer is that modest 5300 defoamer (Deform 5300) of moral, high 825 defoamer (Tego 825) of enlightening, enlightening high 900 disappear
Infusion (Tego Airex 932), Taiwan add up to any one in defoamer and levelling agent D201 (D201).
The beneficial effects of the invention are as follows：
1) resinoid bond of the invention selection epoxy resin, not only with closely knit, water resistant, the features such as intensity is high, and
Also have adhesive force strong, normal-temperature operation, the good manufacturability such as easy construction, and also it is moderate；
2) rational proportion of each component, with reference to the addition of unique temperature-sensitive powder, can not be suitable for transformer stake in arrival
Quick color-changing under the temperature environment of head, to staff with warning function, reduces the possibility that failure occurs, simultaneously for short
The elevated situation of time-temperature, treats that temperature lowers, and color is understood oneself and restored, and staff is had the temperature of transformer pile head
One easier intuitively to recognize；
3) 1250 mesh sericites in powder are added, the unique two-dimensional sheet barrier of sericite in powder, shielding ultraviolet light, chemical constitution
The functions such as stability effectively improve the performances such as permeability resistance, weatherability, the corrosion resistance of film, in addition, sericite in powder is free of
Any radioactive element, can lead the trend of paint field environmental protection.
4) ultraviolet absorber GJ-UV is added in formula component A, intramolecular hydrogen bond can be formed and constitute chelate ring, work as suction
Receive after ultraviolet light, thermal vibration occurs for molecule, hydrogen bond is destroyed, chelate ring is opened, and now compound is in unstable high energy shape
State, in original low energy steady-state phase is returned to, discharges unnecessary energy, so, and high energy, harmful ultraviolet light become
Into low energy, harmless heat energy.
In summary, function admirable of the present invention, raw material is simple and easy to get, easy construction, excellent performance, it is adaptable to extensive work
Industry is produced, after use, and obtained coating not only has the function of reversible temperature indicating, while having excellent sun-proof ultra-violet resistance
Can, future can have good development prospect.
