The preparation method of above-mentioned antisepsis composite material coating, priming coat is sprayed to the surface of substrate, it is rear to carry out for the first time
Roll；Structure sheaf is sprayed to the surface of the remote structure sheaf of priming coat again, rolled for the second time afterwards；Finishing coat is sprayed again
In the surface of the remote priming coat of structure sheaf, the rear third time that carries out rolls.
Preferably, priming coat is sprayed in the ratio of setting, substrate is all covered, thickness reaches standard
0.25mm, must not drain spray, with bubble cut off rolling bubble removing, band rolling roll leveling.It is overall to exert oneself again after half an hour to 1 hour
Roll one time.Structure sheaf is sprayed in the ratio of setting.After spraying, with and followed by rolled, often place roll every time
No less than 10 minutes, integrally roll 2 times, conserve half an hour to 1 hour, next procedure is proceeded by, by the side of first structure layer
Method is implemented, i.e., structure sheaf sprays twice, including first structure layer and the second structure sheaf, increases its intensity.By finishing coat by setting
Ratio sprayed, make structure sheaf all cover, must not drain spray, integrally roll one time.After half an hour to 1 hour, entirety is again
Firmly roll one time, manual mode brushing can also be carried out, completion spraying process tack-free to surface is conserved after completion.
The antisepsis composite material coating is divided into three-layer set, and priming coat is arranged on the surface of chimney substrate, priming coat it is good
Good cementability makes the connection of antisepsis composite material coating and chimney more firm, avoids coming off for antisepsis composite material coating.
The setting of structure sheaf, increase the intensity of antisepsis composite material coating, avoid it from being damaged, meanwhile, priming coat and structure sheaf, knot
Adhesive property between structure layer and finishing coat is preferable, when avoiding its use, falls off between layers.And finishing coat has
There are good Corrosion Protection, resistance to elevated temperatures, anti-wear performance, fire resistance, antioxygenic property and dispersive property, chimney makes
With when temperature it is higher, will not also aoxidize, will not be damaged, extend antisepsis composite material coating service life,
The antisepsis composite material coating is prepared based on the different performance of different layer materials, and its is more excellent.It can be resistant to
Deep-etching, there is low water absorption and high permeability resistant, high intensity and impact resistance, high-adhesive-strength, high temperature resistant and temperature resistance become performance
And globality, the service life of chimney as the antisepsis composite material coating on chimney surface, can be extended.
In detail, preparing the method for priming coat is：By the first solventfree resin, curing agent and the first filler in ultrasonic bar
Priming coat is mixed to get under part.Carried out when preparing priming coat under ultrasound condition, easily produce molecular vibration, make the first nothing
The mixing of Solvent Resin, curing agent and the first filler is more uniform, and adhesive property is more excellent.
Specifically, supersound process 5min-10min is carried out under conditions of ultrasonic power is 200w-500w.With being stirred
Compare, supersound process can make to be well mixed between various material molecules and molecule, the effect of the first curing agent is performed to most
Greatly, the adhesive property of antisepsis composite material coating is more preferable.Every time ultrasound time be 10-20s, it is adjacent twice ultrasound interval when
Between be 5-10s, because ultrasound produces substantial amounts of heat, certain interval of time between adjacent ultrasound twice, avoid instrument from being damaged,
Also the reaction between material can be controlled.Preferably, land plaster and accelerator are ultrasonically treated together, make the effect of priming coat
Fruit is more preferable.
The method of preparation structure layer is：It is in temperature by glass fibre, the second solventfree resin, curing agent and the second filler
100-130 DEG C, pressure be 1.2-1.5MPa under conditions of be stirred to obtain structure sheaf using electric mixer.Glass fibre,
Second solventfree resin, curing agent and the second filler are mixed in the case where temperature is higher, pressure is larger, its mixed effect
Preferably, the intensity of the structure sheaf obtained is more preferable, meanwhile, preparation time, preparation time 1-2h can be shortened.
Preferably, by glass fibre, carbon fiber, the second solventfree resin, curing agent, the second filler and mullite in temperature
Structure sheaf is mixed to get under conditions of being 1.2-1.5MPa for 100-130 DEG C, pressure.Mullite before mixing, also by receiving
Meter level grinder is ground, and obtains nano level mullite material, makes structure sheaf high temperature strength more preferable.
More preferably, by glass fibre, carbon fiber, the second solventfree resin, curing agent, the second filler and mullite electronic
In agitator and temperature be 100-130 DEG C, pressure be mixed to get structure sheaf under conditions of being 1.2-1.5MPa.Mixed in agitator
Close, can largely be manufactured, reduce manufacturing cost.
Preparing the method for finishing coat is：3rd solventfree resin, fire retardant and preservative are mixed at 120-180 DEG C
Nano wearproof material is added after 0.5-1h and curing agent is mixed to get finishing coat.First mix the 3rd solventfree resin and preservative
Close, the antiseptic property of whole finishing coat is multiplied, add nano wearproof material, fire retardant, preservative and curing agent, make
Its tool has good wearability, and is not susceptible to come off, and has good anti-flammability and resistance to elevated temperatures.
Nano wearproof material, antioxidant, modified aniline, fire retardant, preservative and curing agent are added, makes the resistance to of finishing coat
Mill performance is more excellent, and antiseptic effect is more preferable, and the dispersion effect of finishing coat is preferable, can be uniformly dispersed in the table of structure sheaf
Face, antisepsis composite material coating is set to be arranged on after the surface of chimney substrate, the wearability of chimney is very strong, and with anti-well
The effect of corrosion.Meanwhile there is certain anti-flammability, resistance to elevated temperatures, avoid chimney from being damaged, extend chimney uses the longevity
Life.
In the present invention, the thickness of priming coat is 0.2-0.5mm, and the thickness of structure sheaf is 2.0-3.0mm, the thickness of finishing coat
For 0.3-1.0mm.The setting of thickness is carried out according to each layer of characteristic, priming coat mainly plays adhesive property, and structure sheaf mainly makes
The increase of its intensity, and finishing coat mainly plays anti-corrosion, anti-oxidation, fire-retardant and resistant to elevated temperatures effect, in this way, making whole anti-
The performance of rotten composite coating is more excellent, is better able to meet the use demand for being arranged on chimney surface.

As it can be seen from table 1 antisepsis composite material coating prepared by the present invention is arranged on chimney, it will not fall off
And cracking, will not also occur corrosion, oxidation, can high temperature resistant, will not burn, its anti-wear effect is more preferable, this some it is excellent
Performance, antisepsis composite material coating is disclosure satisfy that the use demand on chimney surface.
Experimental example 1
Repeat to prepare embodiment 1-4 antisepsis composite material coatings, and acidproof, water absorption rate and intensity etc. are carried out to it and examined
Survey averages to obtain table 2：
The antisepsis composite material coating test results report of table 2
From Table 2, it can be seen that the water absorption rate of antisepsis composite material coating prepared by the present invention is relatively low, intensity height can be resistant to
High temperature, low temperature resistant, parameters in acid condition are up to standard, have good Corrosion Protection.
