Description
Technical field
The invention belongs to the preparation field of epoxy self-leveling coating, and in particular to a kind of anti-UV epoxy self-levelings finishing coat.
Background technology
Epoxy self-leveling coating is using epoxy resin, special curing agent as main material, by adding various auxiliary agents, pigment, filling out
Material etc., is process through stringent proportioning, not only with chemical characteristics such as excellent water-fast, resistance to greasy dirt, chemicals-resistant corrosion, but also
With adhesive force is good, high mechanical strength, paint film shrinking percentage is low after curing, can once apply the advantages that dressing up thick film, therefore extensive
In covering with paint for modern industry terrace.But the use scope of epoxy self-leveling coating is limited only to interior, use outdoors
It is ineffective.
A kind of epoxy self-leveling coating that can be used for open air is developed, the problem of filling a hole in the market, be urgent need to resolve.
The content of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of anti-UV epoxy self-levelings finishing coat.The finishing coat
Except the excellent performance with common epoxy self-leveling coating, the characteristic for adding mould proof scratch resistance at the same time is gone back, it may have unique
Uv-resistance, problem outdoors, economic and practical, easy construction cannot be used by solving epoxy coating.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of anti-UV epoxy self-levelings finishing coat, is made of component A and B component；Component A is by following raw material group by weight
Into：50-60 parts of epoxy resin, 10-20 parts of acrylic resin, 10-20 parts of iso-octyl glycidyl ether, phenyl glycidyl ether

Part, 10-12 parts of mill base；B component is made of following raw material by weight：10-12 parts of base polyurethane prepolymer for use as and polyamide 8-
10 parts；The weight ratio of component A and B component is 3:1.
Preferably, the anti-UV epoxy self-levelings finishing coat, is made of component A and B component；Component A by it is following by weight
The raw material composition of part meter：55 parts of epoxy resin, 15 parts of acrylic resin, 15 parts of iso-octyl glycidyl ether, phenyl glycidyl
12 parts of ether, 9 parts of barium sulfate, 8 parts of mica powder, 1.2 parts of halloysite nanotubes, the 100-120 mesh quartz sand 15 of nano carbon black load
Part, 1.0 parts of wetting dispersing agent, 1.1 parts of levelling agent, 1.2 parts of defoamer, 2 parts of trimethyl phosphate, 11 parts of mill base；B component is by following
Raw material composition by weight：9 parts of 11 parts of base polyurethane prepolymer for use as and polyamide；The weight ratio of component A and B component is 3:1.
The preparation method of the halloysite nanotubes of the nano carbon black load, concretely comprises the following steps：
（1）Halloysite nanotubes are taken, through mechanical crushing, ethanol wet grinding 10-12h, excessively drying, 100-200 mesh sieves, are obtained short
Cut halloysite nanotubes；
（2）600mL ethanol and 200mL distilled water are measured in 1000mL beakers, adds 5 ~ 10g silane coupling agents, and stir
10min；Then 300-400g steps are added（1）Halloysite nanotubes after processing, and stirred with reinforcement electric mixer
15min, filters, and then dry 2 h at 120 DEG C, are made coupling modifier halloysite nanotubes；
（3）Nano carbon black is scattered in the ethanol solution that volume fraction is 30%, then adds step（2）Obtained coupling changes
Property halloysite nanotubes, ultrasonic disperse 1-2h filters, and ethanol washing, then the dry 1-2 h at 120 DEG C, are made nano carbon black
The halloysite nanotubes of load.
Step（3）The weight ratio of middle nano carbon black and coupling modifier halloysite nanotubes is：1:10-50.
The levelling agent is BYK-354, and the defoamer is BYK-054, and the wetting dispersing agent is BYK-
310。
Nano carbon black is best ultra-violet stabilizer, can be used as UV absorbers.But in multicomponent matrix tree
In the co-mixing system that fat is formed with carbon black, since the polarity of different matrix is different, nano carbon black can produce segregation phenomena, influence face
Flow leveling, adhesive force and the weather resistance of paint.And nano carbon black disperses more difficult in resin system.Galapectite nanometer
Pipe is a kind of alumino-silicate, and strong adsorption, is high reserves energy storage material.
Nano carbon black load is scattered on coupling modifier halloysite nanotubes by the present invention, solves nano carbon black in resin
The problem of middle bad dispersibility, possess excellent UVResistant effect.
The beneficial effects of the present invention are：
1）Nano carbon black load is scattered on coupling modifier halloysite nanotubes by the present invention, since halloysite nanotubes surface has
Have amphipathic, solve the problems, such as bad dispersibility；Halloysite nanotubes have high energy storage at the same time, and a large amount of nano carbon blacks disperse to bear
It is loaded on halloysite nanotubes, has played excellent anti-UV effects；There is halloysite nanotubes certain sustained release-controlled release to make at the same time
With with the extension of epoxy self-leveling finishing coat usage time, nano carbon black can be sustained out, play anti-UV effects for a long time；
2）Addition of the halloysite nanotubes in finishing coat, due to the strong adsorptivity of halloysite nanotubes itself, surface compatibility, increases
The strong adhesive force with middle painting primary coat, can effectively prevent coating and cracks, scratch resistance is good；Halloysite nanotubes are to finishing coat at the same time
In steam also have stronger suction-operated, moistureproof and mildewproof performance is good；In addition tensile strength and hardness are high, and with good
Shock resistance, and noise can be absorbed.
