Description
Technical field
The invention discloses a kind of preparation methods of weather-proof cement-base waterproof coating, belong to water-repellent paint technology of preparing neck
Domain.
Background technology
Water-repellent paint refers to a kind of coating that the film that coating is formed can prevent rainwater or underground water from leaking.Water-repellent paint
It is a kind of architectural waterproof material, is widely used in the waterproof of roofing, basement, toilet bath room and exterior wall etc..Water-repellent paint is usually
By pitch, synthesize macromolecule and cement or with inorganic composite materials etc. for main film forming matter provide, mix suitable nutriment, auxiliary agent,
Solvent type, emulsion type or the response type that solvent etc. is processed into is in viscous liquid without fixed shape at normal temperatures or can
The high molecular synthetic material of the solid powder state of liquefaction.The waterproofing membrane formed after water-repellent paint is cured has certain prolong
Stretching property, elastoplasticity, crack resistance, impermeability and weatherability can play waterproof, prevent blending protective effect.Water-repellent paint has good
Thermal adaptability, it is easy to operate, for ease of maintenaince with maintenance.Waterproof material in the market has two major classes：First, polyurethanes waterproof
Coating, this kind of material are usually to be made as raw material with coal tar of polyurethane, and the tar gas toxicity that it is volatilized is big, and not
It is easy to remove, therefore was prohibited from using in China in 2000, be to replace coal with pitch still in the polyurethane waterproofing coating of sale
Tar is as raw material, general using being diluted containing organic solvents such as toluene, dimethylbenzene but when using this coating, thus
Also contain toxic；It is another kind of be polymer cement-base waterproof coating, the lotion that it is synthesized by a variety of waterborne polymerics with mixed with each
The high grade cement composition of kind additive, polymer（Resin）Flexibility and the rigidity of cement became one so that it is in impermeability
With stability in terms of performance it is excellent, it the advantages of be easy for construction, comprehensive cost low, short time limit, and asepsis environment-protecting.Therefore, gather
Close the leading role that object cement base has become water-repellent paint market.But water-repellent paint used at present shorter interior is easily oozed in the time
The performance of leakage, material surface are detached from, and weatherability is poor and cannot be directly exposed under sunlight, and service life is short, can not meet anti-
The quality index of water functional requirement.
Invention content
The present invention solves the technical problem of：Occur during preparation and use for conventional waterproof coating,
Weatherability is poor, in the presence of a harsh environment, is easily detached from material surface, causes water resistance drastically to decline the problem of even failing, carry
Supply a kind of preparation method of weather-proof cement-base waterproof coating, the present invention that pitch and waste-tyre rubber-powder blending is used to change first
Property portland cement, recycle methyltrimethoxysilane polymerize in hydrolyzed under acidic conditions, then under alkaline condition, through filtering
Polymer microballoon is generated after drying and grinding, and modified portland cement and polymer microballoon powder are finally added to water-repellent paint
In, and add sodium citrate and dopamine hydrochloride etc., it is agitated to be mixed to get weather-proof cement-base waterproof coating.Profit of the invention
The hydrophobic structure to be formed similar to lotus leaf surface is combined with surface concrete in the curing process with polymer microballoon, is utilized simultaneously
Calcium ion in concrete is complexed in dopamine etc., is diffused into concrete pore, reacts to form precipitation with unhydrated cement, blocks
Concrete pore reaches further waterproof effect, strong with concrete binding force, has under severe outdoor environmental conditions long-acting anti-
Water effect, impermeability pressure improve 3 times or more, can large-scale promotion use.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
（1）40~60g pitches are weighed, are poured into iron pan, are heated to 180~200 DEG C, are stirred with glass bar until dripping
Green melting completely, sequentially adds 4~5mL furfurals, 10~20g waste-tyre rubber-powders, continue to be stirred 15 with glass bar~
20min, then 200~300g is added with 4600~4800r/min, 45~60min of rotating speed cutting using emulsification pretreatment blender
Portland cement then continues 2~4h of shearing with 5000~5200r/min rotating speeds, after natural cooling solidification, by object in iron pan
Material is transferred to pulverizer, smashes it through 80~120 mesh sieve, obtains modified portland cement powder, spare；
（2）20~40mL methyltrimethoxysilane is measured successively, and three-necked flask is added in 140~160mL deionized waters
In, dropwise addition mass fraction is 8~10% hydrochloric acid, adjusts pH to 2.2~2.6, then flask immigration digital display is tested the speed temperature constant magnetic stirring
It it is 40~45 DEG C in temperature, under the conditions of rotating speed is 300~400r/min, constant temperature is stirred to react 3~5h in device；
（3）To the end of reaction, 55~60 DEG C are adjusted the temperature to, speed of agitator to 400~600r/min stirs shape in constant temperature
Under state, dropwise addition mass fraction is 10~15% ammonium hydroxide, adjusts pH to 10.5~10.8, continues thereafter with constant temperature and be stirred to react 2~4h,
It filters while hot, removes filtrate, filter cake is washed with deionized until cleaning solution is in neutrality, then gained filter cake is transferred in baking oven,
It dries under the conditions of being 105~110 DEG C in temperature and is placed in mortar to constant weight, then by the filter cake after drying, grind 10~15min,
Obtain polymer microballoon powder；
（4）It counts in parts by weight, sequentially adds 60~65 parts of portland cements in batch mixer, 20~30 parts of quartz sands, 3
~5 parts of calcium hydroxides, 2~4 parts of sodium lignin sulfonates, 15~20 parts of steps（1）Spare modified portland cement powder, 10~15
The above-mentioned resulting polymers microsphere powder of part, 3~5 parts of neopelexes, 4~6 parts of sodium citrates, 8~10 parts of dopamines
Hydrochloride, 200~220 parts of deionized waters are 60~65 DEG C in temperature, and under the conditions of rotating speed is 1200~1400r/min, constant temperature stirs
45~60min of mixing is mixed to get weather-proof cement-base waterproof coating.
The application process of the present invention：3 are rinsed through manually the concrete surface for doing waterproof will be needed to polish flat, then with clear water
~5 times, surface contaminants are removed, weather-proof cement-base waterproof coating obtained by the present invention is dipped using hairbrush, is applied to concrete table
Face, control brushing thickness is 1.0~1.2mm, to the end of brushing, 8~12h of room temperature curing, then plastic covering film, maintenance 2~4
It, you can.After testing, agent on crack resistance of concrete consolidation pressure improves 3~5 times compared with using conventional waterproof material, and service life extends 6~
It 8 years, in use, does not leak.
The beneficial effects of the invention are as follows：
（1）Gained water-repellent paint water resistance of the invention is good, brushes 1.0~1.2mm thickness, impermeability pressure can be made to improve
3 times or more, and in the case where there is water condition, waterproof material penetrates into inside cement, forms crystallization, it can self-heal crack；
（2）Gained water-repellent paint of the invention is nontoxic and pollution-free, and production and construction techniques are simple, and weather-proof strong, environment adapts to
Property is strong, is suitable for large area complex surface concrete works, in underground engineering, hydraulic engineering, power bridge, cistern, building
In the engineering waterproofings such as roofing, have a good application prospect.
Specific implementation mode
40~60g pitches are weighed, are poured into iron pan, are heated to 180~200 DEG C, with glass bar stirring until pitch
Melting completely, sequentially adds 4~5mL furfurals, 10~20g waste-tyre rubber-powders, continue to be stirred 15 with glass bar~
