Description
Technical Field
The invention relates to a coating, in particular to a coating with hydrophilic self-cleaning capability and a preparation method thereof.
Background
With the rapid development of economy, the infrastructure of China is continuously improved and developed, the problem of cleaning various buildings such as skyscrapers, giant stone carvings, large billboards and the like becomes a great problem, the traditional manual cleaning method not only consumes time and labor and has extremely high cost, but also has great potential safety hazard in cleaning work. In order to overcome the problems, in recent years, a plurality of antifouling paints applied to the outer wall of the building are developed, and the antifouling materials can reduce the deposition of pollutants on the surface of the building and delay the pollution of the outer wall of the building to a certain extent. However, the material is a temporary solution and a permanent solution, and according to the feedback discovery of the effect of the current practical application, the common antifouling paint in the market at present has the following defects:
firstly, the mechanical strength of the material is insufficient: the current antifouling material is basically a simple aqueous phase or alcohol phase solution, and is naturally solidified on the surface of the outer wall of the building by a spraying or wiping method. The bonding method is basically simple van der waals force or hydrogen bonding, has extremely low mechanical strength, and is difficult to resist the corrosion of natural conditions such as long-term wind blowing, sun exposure, rain and the like. Therefore, functional materials such as super-hydrophilic materials, photocatalytic materials and the like in the solution can be stripped from the surface of the coating, the coating can gradually lose the functional effects such as super-hydrophilicity, photocatalysis and the like, and the coating can be separated from the surface of the base material, so that the coating effect is completely lost;
secondly, the photocatalytic performance is lower: the photocatalyst adopted by the existing antifouling coating is basically titanium dioxide, the titanium dioxide really endows the material with photocatalytic performance, and the hydrophilicity of the coating can be improved to a certain extent, but the requirement of the titanium dioxide on a dissolving system and the particle size is extremely high, if a better dissolving system and a smaller particle size do not exist, the antifouling material added with the titanium dioxide can generate obvious white floccules, the transmittance of the coating on a series of base materials such as glass and the like is directly influenced, and the applicability, the operation simplicity and the attractiveness of the antifouling coating are reduced. In addition, as a photocatalyst which is relatively well researched, the lower photoelectric conversion efficiency and the lower visible light utilization rate of the titanium dioxide are always problematic, and the two defects also limit the application effect of the titanium dioxide as the photocatalyst in an antifouling material;
thirdly, poor removal capability of solid particles: in the time period of drought and rain, wind sand and flying dust are main pollution factors on the surface of a building, sand, dust and other solid pollutants with small particle size are easily adsorbed on the surface of the building under the condition, and the pollutants are gradually deposited and solidified when the rain wash is not in time, so that the pollutants are remained on the surface of an outer wall of the building, and the attractiveness of the building is influenced. Thus, conventional antifouling materials have difficulty in resisting such solid particulate contamination during rainy seasons or areas lacking rain water.

Detailed Description

Unless otherwise defined, all terms of art used hereinafter have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the present invention.
A coating with hydrophilic self-cleaning capability comprises 80-100 parts by weight of hydrophilic solvent, 0.01-10 parts by weight of precursor monomer, 0.01-0.5 part by weight of chain initiator, 0.01-1 part by weight of silane coupling agent, 0.01-1 part by weight of photoinitiator and 0-1 part by weight of antistatic agent; the precursor monomer comprises one or more of polyethylene, polypropylene, polyvinyl chloride, polystyrene and derivatives thereof with crosslinking, interconnection or polymerization; the precursor monomer forms a network structure after crosslinking, interconnection or polymerization; the antistatic agent comprises one or more of alkyl quaternary ammonium salt, alkyl phosphonium salt, alkyl sulfonic acid alkali metal salt, alkyl phosphoric acid alkali metal salt, alkyl dithio-carbamic acid alkali metal salt and ethoxylated fatty alkylamine.
Antistatic agents are additives that are added to plastics or applied to the surface of molded articles to reduce static buildup. The antistatic agent is added into the coating, so that the resistivity of the surface of the material is reduced, solid small particles are difficult to adsorb on the surface of the base material, and the cleanness of the surface of the base material is kept.
In the present invention, the silane coupling agent includes one or more of vinyl silane, amino silane, epoxy silane, mercapto silane, and methacryloxy silane. The silane coupling agent is rich in siloxane groups and organic functional groups, wherein the siloxane groups have reactivity with inorganic substances, and the organic functional groups have reactivity or compatibility with organic substances. Thus, when a silane coupling agent intervenes between the inorganic and organic interfaces, a bonding layer of organic matrix-silane coupling agent-inorganic matrix may be formed. When the material is applied to the material, a bridge can be erected between the coating and the base material, and the adhesion of the coating on the base material is improved. It should be noted that the selection of the corresponding silane coupling agent should be easily soluble in the whole solution system, and cannot cause flocculation and precipitation reactions, which may damage the overall transparency of the solution. The silane coupling agent can be directly added into the precursor solution in the form of solution, or can be hydrolyzed in advance and then added into the precursor solution, and different adding modes are selected according to the characteristics of different silane coupling agents.
In the invention, the chain initiator comprises one or more of azo initiator, redox initiator, bifunctional and multifunctional initiator series. The chain initiator is a compound which is easily decomposed into free radicals (namely primary free radicals) by heating, can be used for initiating free radical polymerization and copolymerization of alkene and diene monomers, and can also be used for crosslinking curing and high polymer crosslinking of unsaturated polyester. In the present invention, the chain initiator mainly helps the precursor to polymerize into chains in the solution, and provides for the next crosslinking to form a network structure. The chain initiator can be directly added into the solution or dissolved in advance, and the adopted solvent comprises one or more of ethanol, methanol, propylene glycol methyl ether and the like.
The photocatalyst is also called photocatalyst, and is a generic name of semiconductor materials having a photocatalytic function represented by nano-sized titanium dioxide. A typical photocatalytic material is titanium dioxide, which generates a substance having a strong oxidizing property (e.g., hydroxyl radical, oxygen, etc.) under light irradiation, and is useful for decomposing organic compounds, partially inorganic compounds, killing bacteria and viruses, etc. The photocatalyst is added into the coating, so that the removal capability of the coating on organic pollutants in the air can be improved, the organic pollutants attached to the coating can be decomposed through a photoelectric reaction, and the effect of keeping the surface of the base material clean is finally achieved. The photocatalyst applied by the invention should be a nano-scale photocatalyst, including but not limited to a series of photocatalytic materials such as doped titanium dioxide, composite titanium dioxide, graphene, bismuth ferrite, bismuth vanadate, carbon nitride and the like, and in addition, the nano-scale photocatalyst can be directly prepared by a production unit through a separate preparation method. The photocatalyst is dissolved in a corresponding solution system in advance, so that the photocatalyst can be combined in the whole coating layer in the later reaction to the maximum extent, and the stability and the transparency of the solution are maintained.
In the present invention, the coating material may further contain a pH adjuster including one or more of dilute hydrochloric acid, perchloric acid and sodium hydroxide solution, or other pH adjusters may be used.

Example 1
In this embodiment, a precursor acrylamide is used to prepare a polymer material, and the polymer material is modified to have hydrophilicity, and the specific preparation process is as follows:
14.216 g of acrylamide solid is dissolved in 100 mL of ultrapure water, the solution is stirred for 3min at the rotation speed of 200 rpm in a water bath kettle at the temperature of 30 ℃ to be fully dissolved, then 0.1 mL of (3-mercaptopropyl) trimethoxysilane solution is added, the volume fraction of the (3-mercaptopropyl) trimethoxysilane solution is 10 percent, the diluent of the (3-mercaptopropyl) trimethoxysilane is tetrahydrofuran, then 1 mL of acetic acid solution with the concentration of 0.1 mol/L is added, then 0.57 mL of silane coupling agent TMSPMA is added, the mixture is stirred for 5 min at the temperature of 30 ℃, finally 0.2 mL of 0.1 mol/L photoinitiator I-2959 is added, and the mixture is stirred for 10min and then stands for standby;
spraying the prepared coating on toughened glass by a high-pressure spray gun, naturally drying for 24 hours, and then curing to form a film, wherein the transparency of the coating is measured by observing the light transmittance of the glass surface; judging the hydrophilicity of the solution through a water contact angle; the hardness of the coating layer on the surface of the glass is judged by rubbing for 50 times by a rubbing machine; judging the anti-aging performance of the coating layer on the surface of the glass through a xenon lamp aging test of 50 hours, and measuring the photocatalysis performance of the coating through a removal test of methylene blue liquid drops with the concentration of 5 mg/L; the antistatic properties of the coating were measured by observing the retention of the powder on the glass surface.
The coating according to the invention was tested by the test method described in the supplementary contents of the examples, the test results of example 1 are shown in table 1, and based on the test results we found that example 1 already has hydrophilic properties and at the same time has good hardness and aging resistance, but the coating described in example 1 has poor transparency, which severely limits the application range of the coating. The inventors searched a large number of documents and found that the concentration of the precursor has a great influence on the viscosity of the coating layer, and therefore, it is presumed that the transparency of the coating layer can be improved by lowering the concentration of the precursor, and thus, example 2 and example 3 were designed.
Example 2
The amount of acrylamide added in step (1) was changed to 7.1797 g, and the amounts of other test materials and the preparation steps were the same as those of example 1 to obtain the coating material prepared in example 2, and then the same coating method and measurement method as those of example 1 were performed to measure the properties of the coating material prepared in example 2;
example 3
The amount of acrylamide added in step (1) was changed to 3.5899 g, and the amounts of other test materials and the preparation steps were the same as those of example 1 to obtain the coating material prepared in example 3, and then the same coating method and measurement method as those of example 1 were performed to measure the properties of the coating material prepared in example 3;
from the effects of examples 2 and 3 shown in table 1, it can be seen that the transparency of the coating is indeed improved by reducing the concentration of the precursor, but as the concentration of the precursor is reduced, the anti-aging performance and hardness of the coating are gradually reduced, which leads to the coating losing its hydrophilicity and anti-fouling performance very quickly, so that a better precursor concentration, which has both good transparency and good anti-aging performance and hardness, needs to be found.
Example 4
The amount of acrylamide added in step (1) was changed to 5.3848 g, and the amounts of other test materials and the preparation steps were the same as those of example 1 to obtain the coating material prepared in example 4, and then the same coating method and measurement method as those of example 1 were performed to measure the properties of the coating material prepared in example 4;

Example 4 | √ | √ | √ | √ | × | × |
Note: in the table, "×" indicates that the coating had no or poor properties, and "√" indicates that the properties are superior
The results in Table 1 show that the transparency of the coating gradually improves with decreasing precursor concentration, but the hardness and the aging resistance are attenuated. The inventor finds out a better precursor concentration through a large number of literature consultations and experimental verifications so as to carry out the next experiment. Meanwhile, it can also be seen that the coatings described in examples 1 to 4 do not have antistatic and photocatalytic properties and do not achieve the desired effects because no photocatalyst and antistatic agent are added, and the following examples are listed for discussion.
Example 5
The amount of acrylamide added in step (1) in example 1 was fixed at 5.3848 g, and step (2) and step (3):
(2) preparation method of graphite phase carbon nitride
First, melamine was put in a muffle furnace at 5 ℃ for min-1Heating to 500 ℃ at a heating rate and maintaining for 4 hours to synthesize flake g-C3N4Solid, then flake g-C3N4Ground into a powder for further use. Then 1 g of flakes g-C3N4Placing into a ceramic crucible at 2.3 deg.C for min-1Is heated to 550 ℃ and kept for 2 hours to obtain the twice calcined g-C3N4Nanosheets. Subsequently, under sonication, 200 mg of g-C3N420 mL HNO for nanosheet3And H2SO4And oxidizing for 18 hours. The clear isThe clear solution was diluted with 300 mL of deionized water to form a colloidal suspension, filtered through a 0.45um microporous membrane to remove the acid, and washed with deionized water to obtain g-C3N4Nanobelts (CNNR), isolation yield about 50% CNNRs were dispersed in 20 mL of deionized water under ultrasonic conditions for 2h, and then the suspension was transferred to a 20 mL teflon-lined stainless steel autoclave and heated at a temperature of 200 ℃ for 10 h. Finally, after naturally cooling to room temperature, the resulting solution was filtered through a 0.22 μm microporous membrane to obtain colorless g-C3N4Quantum dots (graphite phase carbon nitride).

the performance effects of the coatings described in examples 5-8 are shown in Table 2, and the addition of carbon quantum dots imparts photocatalytic performance to the coatings, but does not impart antistatic properties to the coatings; antistatic properties can be achieved by the specific addition of antistatic agents to the solution.
Example 9
The amount of acrylamide added in step (1) was fixed to 5.3848 g, the amount of carbon quantum dots added in step (3) was fixed to 1mg, antimony tin oxide was added as an antistatic agent to the solution so that the final mass fraction was 2 ‱, the amounts of other experimental materials and the preparation steps were the same as those of example 5, to obtain the coating material prepared in example 9, and then the same coating method and measurement method as those of example 1 were performed to measure the properties of the coating material prepared in example 9.
