Description
Technical field
The present invention relates to a kind of weathering resistance coatings coating and preparation method thereof, and in particular to a kind of for pre-installed and inverted adhered waterproof volume
Weathering resistance coatings coating of material protective layer and preparation method thereof.
Background technology
After pre-installed and inverted adhered waterproof roll introduces Chinese market from the nineties in 20th century, by its excellent leakage-proof performance,
Quickly grow at home, be widely used in underground engineering, cut and cover method Tunnel Engineering, subsurface excavation method Tunnel Engineering, underground pipe gallery is prevented
The major projects such as Hydraulic Projects.Pre-installed and inverted adhered waterproof roll typical construction includes main water barrier, adhesive layer and protective layer, its
The Main Function of middle protective layer is Protection glue adhensive layer from outside contamination, isolation ultraviolet and oxygen environment, protection adhesive
There is no chain rupture disability by ultraviolet ray ageing in layer.Therefore, the shielding ultraviolet rays performance of protective layer is for pre-installed and inverted adhered waterproof roll
UV resistance influence it is very big.
Typically using empty laid process construction, be laid on for pre-installed and inverted adhered waterproof roll in advance anti-by pre-installed and inverted adhered waterproof coiled material construction
Water position, then assembling reinforcement, last casting concrete treats after the completion of concrete hydrating that protective layer is together with main water barrier and glue
Adhensive layer forms permanent adhesive layer with rear pouring concrete, reaches the effect of " skin-type " waterproof.But, some underground engineerings,
In the work progress of cut and cover method Tunnel Engineering, after laying pre-installed and inverted adhered waterproof roll, in addition it is also necessary to assembling reinforcement, coagulation can be just poured
Soil, pre-installed and inverted adhered waterproof roll will be fully exposed to be exposed to the sun under the ultraviolet of sunlight during this, particularly be shone in some ultraviolets
Strong area and low latitudes high temperature area is penetrated, ultraviolet irradiation is stronger.If running into special circumstances, project progress progress
In the case of slow, pre-installed and inverted adhered waterproof roll can expose and be exposed to the sun in the sun 2 months, even more long.Such as run into more than 2 months
Open air be exposed to the sun, pre-installed and inverted adhered waterproof roll is easy to the aging disability of adhesive layer, so as to influence pre-installed and inverted adhered effect,
It is difficult to reach good " skin-type " leakage-proof effect.
At present, pre-installed and inverted adhered waterproof roll protective layer carries out protection adhesive using mineral grain or artificial synthesized particle
The method of layer.For example, prior art CN104057686A is disclosed with the weather-proof mineral grain function with cement reactivity
Layer with the materials such as alumine, aluminum oxide it is size-reduced, fire, cooling, crush, screening, washing, drying etc. technique it is artificial synthesized
Mineral grain.Can be with shield portions shielding ultraviolet rays, because its mineral grain is covered in although the method is made protective layer
Adhesive layer surface is unable to reach 100% continuous covering, therefore is unable to reach the effect of complete shielding ultraviolet rays.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of weather-proof painting for pre-installed and inverted adhered waterproof roll protective layer
Coating and preparation method thereof, the weathering resistance coatings coating mainly solves to irradiate strong area and low latitudes high temperature ground in ultraviolet
Area, pre-installed and inverted adhered waterproof roll was exposed to the sun more than 2 months in the sun, it is even more prolonged in the case of, still can effectively shield purple
Outside line, protects adhesive layer not irradiated by ultraviolet and destroys.
The present invention solve its technical problem use technical scheme be, a kind of weathering resistance coatings coating, in parts by weight, including
Following components：10~40 parts of water, 10~50 parts of acrylic emulsions, 20~70 parts of filler, 0.1~1 part of ultraviolet absorber, nanometer
1~30 part of zinc oxide, 0.1~5 part of dispersant, 0.1~5 part of wetting agent, 0.5~5 part of defoamer, 0.1~5 part of levelling agent increases
Thick dose 0.1~5 part.
Further, the nano zine oxide is zinc oxide content >=98%, Electronic Speculum average grain diameter≤50nm commercially available prod.
Further, the water is deionized water, the running water of pure water, distilled water or soft.
Further, the acrylic emulsion is vinegar-acrylic emulsion, styryl acrylic emulsion, pure-acrylic emulsion, silicon-acralyte latex uncle and carbonic acid
One or more mixture in ester emulsion.
Further, described filler is the one kind in powdered whiting, precipitated calcium carbonate, titanium dioxide, kaolin and wollastonite
Or two or more mixtures.
Further, the ultraviolet absorber is salicylic acid esters, benzophenone class, benzotriazole, group-substituted acrylonitrile and three
One or more mixture in piperazine class and hindered amines.
Further, the dispersant is selected from the mixed of one or more in polyacrylic acid sodium salt, ammonium polyacrylate salt
Compound, such as DP270, DA40 and 5040 etc., the wetting agent is selected from APES class, alkylsurfuric acid salt, sulphur
One or more mixture in Barbiturates, such as DM-410, NP10 and X405 etc., the defoamer are selected from mineral oil

Selected from one or more mixed in pure acrylic acid class levelling agent, modified acrylic acid levelling agent, silicone levelling agent
Compound, such as ASE-60, Polyflow S, NO.90 and KL-700 etc., the thickener are selected from swelling great soil group thickener, fiber
One or more mixture in plain ethers thickener, polyacrylamide thickener, such as TT-935, RM-8W,
HEC440 and D105 etc..
The present invention further solve its technical problem use technical scheme be, a kind of preparation side of weathering resistance coatings coating
Method, comprises the following steps：
(1) by the accurate water weighed with nano zinc oxide powder phase homogenous quantities of formula, add the dispersant of gross mass half with
Nano zinc oxide powder is premixed, and activation process is carried out through ultrasonic cumulative reactor, is taken out standby；
(2) remaining water is accurately weighed by formula, is added in dispersion cylinder, stirred with 100 revs/min；Then accurately weigh
The dispersant of gross mass half, wetting agent and defoamer, add in dispersion cylinder, are stirred 2~3 minutes with 100 revs/min, and stirring is equal
It is even；Then mixing speed is improved to 200 revs/min, the filler for accurately having weighed is slowly uniformly added into, and has been added within 10~15 minutes
Finish, be evenly stirred until that fineness is less than 50 μm；
(3) acrylic emulsions are accurately weighed, dispersion cylinder is slowly uniformly added into, charging in 5~8 minutes are finished, with 200 turns/
Dispersion 4~5 minutes, stirs；Then levelling agent, thickener, ultraviolet absorber, preservative are accurately weighed, dispersion is added
Cylinder, is disperseed 4~5 minutes with 200 revs/min, is stirred；It is last accurately to weigh nano zine oxide after activation process, add dispersion
