Abstract
The invention relates to the technical field of ground skid resistance and indoor environmental protection, and particularly discloses development and application of a multifunctional polymer-based surface-cleaning skid resistance technology. The preparation method of the ceramic tile containing the polymer-based anti-skid film comprises the following steps: 15-30 parts of prepolymer polymer, 5-10 parts of emulsifier, 0.1-1 part of photoinitiator, 5-10 parts of hydrogenated titanium dioxide, 1-5 parts of sodium carbonate and 50-100 parts of deionized water, wherein the parts are in mass proportion. Coating the anti-slip liquid on a ceramic tile substrate, and under the irradiation of an ultraviolet lamp, pre-polymerizing high polymers for crosslinking and condensation to form a bionic porous film on the ceramic tile, wherein the pore structure of the bionic porous film has the negative pressure physical sucking disc effect under the water/oil wetting condition, so that an excellent anti-slip effect is formed. In addition, the hydrogenated titanium dioxide component enables the anti-skid film to have rich surface charges, and a super-hydrophilic self-cleaning effect is formed; under the irradiation of visible light, the surface of the film can also effectively remove formaldehyde components in indoor air.
Description
Technical Field
The invention relates to the technical field of ground skid resistance and indoor environmental protection, and particularly discloses a preparation method of a novel hydrogenated titanium dioxide/porous polymer composite film on a ground substrate and application of the novel hydrogenated titanium dioxide/porous polymer composite film in three aspects of skid resistance, self-cleaning and indoor formaldehyde removal.
Background
The surface of the ground base materials such as ceramic tiles and toughened glass becomes wet and slippery after meeting water, the number of hospitalizations such as fracture and sprain caused by the wet surface base materials accounts for 35% of all accidental injuries, and the ground skid resistance is a new problem of public safety. Traditional safety anti-skid products such as anti-skid pads/anti-skid bricks have higher cost and low performance under water/oil wetting. Therefore, the development of the efficient and universal surface anti-skid treatment technology has extremely high application prospect and market demand.
The most common anti-slip treatment technique at present is to etch a high roughness surface on the surface of a substrate by using a composite preparation (common anti-slip liquid), so that the surface friction coefficient of the substrate is improved to a safe level. However, the main raw materials of the anti-skid liquid are mostly highly toxic and highly corrosive reagents such as hydrofluoric acid, sodium hydroxide and the like, which obviously damage base materials and have great harm to indoor environment and human body; in addition, the rigid rough surface produced by etching is easy to wear, the duration of the anti-slip effect is very limited (3-6 months), and repeated etching maintenance is needed. Therefore, the environmental protection property and the treatment effect of the anti-skid products far do not meet the application requirement of universality. In addition, foreign companies such as 3M and basf have developed products such as non-slip resin and non-slip adhesive for the ground to solve the problem of non-slip. However, these products have major limitations for large-scale deployment due to their high cost and short lifetime (< 2 months).
On the other hand, the ground substrate is damaged by the etching type antiskid technology, and pollutants such as dust particles and the like are easily accumulated on the rough surface of the ground substrate, so that the ground cleaning and the indoor environment safety are seriously influenced. According to relevant commodity inspection data, the conventional etching type anti-slip liquid in the market is only suitable for application scenes with low environmental requirements such as industrial plants and the like at present, and the problems of increase of volatile organic compounds and the like caused by the conventional etching type anti-slip liquid are far from meeting the environmental protection application requirements of normal houses and large public places thereof.
In conclusion, the invention needs to construct a high-performance green anti-skid technology, and simultaneously, corresponding components are added to enable the surface of the anti-skid treated ceramic tile to have a self-cleaning function, so that the problems of limited performance and high pollution of the existing anti-skid technology are fundamentally solved.
Disclosure of Invention
In order to solve the above problems, the present invention uses a prepolymerized polymer, sodium carbonate, hydrogenated titanium dioxide, or the like as raw materials for an anti-slip agent; the organic/inorganic composite bionic structure porous array is formed on the surface of the base material, so that the ground and the sole can contact to form the bionic physical sucker effect, and the friction coefficient of various ground base materials is obviously enhanced. On the other hand, the hydrogenated titanium dioxide component added into the anti-skid agent by research and development teams enables the surface of the ceramic tile to have a good self-cleaning effect; under the conditions of visible light irradiation and high-efficiency indoor air circulation, the ceramic tile processed by the technology can effectively remove formaldehyde components in the indoor air. The practical application effect shows that the treated ground has stable and lasting effects (more than or equal to 18 months) in three aspects of skid resistance, formaldehyde removal and self-cleaning.
The details are as follows:
(1) a pre-treatment cleaning process for floor tiles:
(a) firstly, preparing a pretreatment solution: 5-20 parts of potassium fluoride, 10-30 parts of citric acid, 1-10 parts of calcium stearate, 1-5 parts of surfactant, 0.1-1 part of polyvinyl alcohol and 50-100 parts of deionized water (parts are mass ratio);
(b) uniformly coating the pretreatment solution on the surface of a tile-making substrate (the using amount is 50-80mL/m2), and standing for 30 min;
(c) washing with purified water;
(2) preparation and application of a macromolecular base anti-slip liquid are as follows:
(a) preparing a polymer-based anti-skid liquid: 15-30 parts of prepolymer polymer, 5-10 parts of emulsifier, 0.1-1 part of photoinitiator, 5-10 parts of hydrogenated titanium dioxide, 1-5 parts of sodium carbonate and 50-100 parts of deionized water (parts are mass ratio);
(b) uniformly coating the surface of a tile-making substrate (the using amount is 30-50mL/m2) with the macromolecular anti-skid liquid, and irradiating for 5min by ultraviolet light;

Detailed Description
In order to make the technical solutions of the present invention better understood and enable those skilled in the art to practice the present invention, the following embodiments are further described, but the present invention is not limited to the following embodiments.
Example 1
Constructing a polymer-based anti-skid film on the surface of the ceramic tile by adopting a pretreatment process and an in-situ polymerization segmentation method (figure 1): firstly, uniformly dispersing the prepared pretreatment solution to the surface of a ceramic tile substrate in an atomizing and spraying manner, wherein the using amount is about 30-50mL/m 2; subsequently, the tile floor coated with the pretreatment solution was left to stand for 30min, during which the pretreatment process was monitored using the pH as a standard parameter. The initial pH of the fish tail was 2.5 and when the pH rose to 3.5, the pretreatment cleaning process was complete. Washing the ground with a large amount of purified water; a Zeta potential instrument is adopted for characterization, and the surface of the ceramic tile is provided with high-density positive electricity, which shows that the method successfully removes organic substances on the surface of the ceramic tile and enables the surface of the ceramic tile to have stronger interaction force on the negatively charged prepolymer. Secondly, uniformly coating the prepared polymer-based anti-slip liquid on the surface of a ceramic tile substrate by a scraper, wherein the using amount of the prepared polymer-based anti-slip liquid is about 30-50mL/m2, and then irradiating by using an ultraviolet lamp with the wavelength of 365nm, wherein the irradiation speed is 5min/m2(10m2 space can be irradiated simultaneously); after the surface of the ceramic tile is solidified, the ceramic tile is washed by purified water and naturally dried, and an anti-skid film with the thickness of 0.5mm is formed on the surface of the ceramic tile (figures 2 and 3).

Example 2
The hydrogenated titanium dioxide in turn gives the slip-resistant film an abundant surface charge. In this case, a weak polar liquid such as vegetable oil, liquid paraffin or the like is dropped on the surface thereof or repelled and bounced, resulting in an strongly oleophobic property. On the contrary, strong polar liquid such as water, ethanol and the like can be quickly adsorbed and spread on the surface to form super-hydrophilic property. This results in a significant self-cleaning effect of the anti-slip film. Before the anti-skid film is treated, the surface of the glass substrate is stained with ash, and the glass substrate is washed by aqueous solution, so that the surface of the glass substrate is dirty with ash and water; after the treatment of the anti-skid film, the dyed ash is very clean when being washed by aqueous solution.
Example 3
The titanium dioxide component is hydrogenated, so that the anti-skid film has a certain indoor environment-friendly function. Titanium dioxide is a very common photocatalytic material, and a plurality of research works show that the titanium dioxide can effectively degrade formaldehyde in the air through ultraviolet irradiation; however, the ultraviolet light source has significant biological toxicity, and is not realistic for long-term use in a living environment. The group prepares a series of hydrogenated titanium dioxide with visible light absorption effect by hydrogen plasma treatment, and the material can degrade formaldehyde under the irradiation of visible light. The anti-skid film is used as an added component of the anti-skid film, and the experimental result of an atmosphere simulation box shows that 1 square meter of processed ceramic tile can degrade indoor polluted air with 2 cubic meters of formaldehyde content reaching 0.5 milligram/cubic meter to clean air meeting the national standard after being irradiated for 10 hours by simulated sunlight, and the formaldehyde degradation effect is obvious (figure 4)
Example 4
The preparation process is the same as that of example 1, except that: the dosage of the polymer-based anti-skid liquid is increased to 100mL/m2, so that the anti-skid film with a light yellow surface is obtained, the anti-skid performance of the anti-skid film is improved, but the light transmittance is poor, and the anti-skid film is only suitable for dark ceramic tiles to a certain extent.
Example 5
The preparation process is the same as that of example 1, except that: by shortening the UV irradiation time to 1min/m2, the performance of the obtained anti-slip film is not significantly affected, but the durability is significantly reduced.
Example 6
The preparation process is the same as that of example 1, except that: the pretreatment time is shortened to 10min, the performance of the subsequently formed anti-skid film is not obviously influenced, but the anti-skid film is easy to form lamella peeling.
Example 7
The preparation process is the same as that of example 1, except that: the molecular weight of the used prepolymer is further improved, and the uniformity of the obtained antiskid film is greatly influenced, so that the formation of a uniform and compact porous array is not facilitated.
Example 8
The preparation process is the same as that of example 2, and only differs from the following steps: the high molecular film does not have the self-cleaning function without adding the hydrogenated titanium dioxide component.
Example 9
The preparation process is the same as that of example 2, and only differs from the following steps: if the anti-slip film is periodically irradiated with visible light, the self-cleaning function of the polymer film is greatly reduced.
Example 10
The preparation process is the same as example 3, except that: the high molecular film does not have the function of degrading formaldehyde without adding the hydrogenated titanium dioxide component.
Example 11
The preparation process is the same as that of example 2, and only differs from the following steps: if the indoor air is not forced to circulate, the function of the polymer film for degrading formaldehyde is greatly reduced to a certain extent.
