Description
Technical Field
The invention relates to the field of environment-friendly materials, in particular to an environment-friendly decorative material and a preparation method thereof.
Background
With the development of economy, people pay more attention to green and healthy living environments. In the aspect of indoor decoration, as the traditional wall building materials, paint and the like usually volatilize some toxic substances such as formaldehyde and the like to endanger human health, the development of wallpaper conforms to the environmental protection concept, and the traditional wall finishing materials have the advantages of convenience in use, various styles, low price and the like, and are challenging to the position of the traditional wall finishing materials in indoor decoration.
At present, wallpaper varieties in the market are various, such as pure paper wallpaper, fabric wallpaper, metal wallpaper, natural material wallpaper, PVC wallpaper and the like, and although the wallpaper has respective advantages, the wallpaper has some defects, such as the pure paper wallpaper has good environmental protection performance, but is not waterproof, moisture-proof, scrubbing-proof and the like, is not easy to handle, has higher requirements on construction technology, and can easily generate obvious joints once being improperly operated; although the PVC wallpaper has sound absorption effect, high cost performance and easy management, the PVC wallpaper has poor air permeability and is not environment-friendly; fabric wallpaper, such as silk wallpaper and brocade wallpaper, cannot be widely popularized due to the defects of high price, difficult management and the like; although natural wallpaper has strong local smell and natural and primitive texture, the durability and the fireproof performance are poor. Thus, the environment-friendly nonwoven wallpaper is unique. The non-woven wallpaper is a novel high-grade wall decoration material which is prepared from natural fibers such as cotton and hemp or synthetic fibers such as terylene and acrylon through non-woven molding, resin coating or hot rolling sizing, printing and other procedures. It is popular with more and more consumers because of the advantages of difficult breaking and aging, soft texture, certain moisture resistance, air permeability and the like.
At present, researches on non-woven wallpaper are focused on the fields of wear resistance, antibiosis and mildew resistance, static resistance, flame retardance, formaldehyde removal and the like, and can be roughly divided into two aspects of improving the mechanical property and the chemical property of the non-woven wallpaper. The improvement of the mechanical property is usually from the perspective of improving the non-woven fabric material or adding the inorganic filler, is environment-friendly, and is not easy to generate substances harmful to human bodies, however, the improvement of the chemical property is usually carried out by using a large amount of organic solvents, is not environment-friendly, and can also generate harm to human bodies. Especially when the photocatalyst material is applied to remove formaldehyde, the organic solvent is used as a film forming agent, so that the dispersibility and the solid-borne time of the photocatalyst material on the non-woven fabric are enhanced, the photocatalyst material is easy to decompose to generate harmful substances, the photocatalyst material can further decompose the non-woven fabric, and the service life of the non-woven fabric wallpaper is reduced. The photocatalyst material is a material which can be used for catalyzing and degrading formaldehyde under the room temperature illumination condition rarely in the prior art, and has the defect of poor catalytic degradation capability under the visible light, and the generated oxidative free radicals are easy to damage wallpaper, so that the research direction of how to improve the degradation capability under the visible light and to fixedly load the photocatalyst material on the wallpaper without damaging the wallpaper is very significant.
CN 110373915A discloses an environment-friendly non-woven wallpaper capable of absorbing and degrading formaldehyde and a preparation process thereof, wherein aqueous acrylic acid is used as an adhesive, nano manganese dioxide is fixed on the surface of the non-woven, the adhesive and the non-woven are greatly corroded due to extremely strong oxidizing property of the manganese dioxide, and the manganese dioxide is easy to deactivate due to the reaction of the manganese dioxide and formaldehyde, so that the prepared non-woven has a lower service life.
Disclosure of Invention
Aiming at the defects existing in the prior art, the invention provides an environment-friendly decorative material and a preparation method thereof.
The preparation method of the environment-friendly decorative material comprises the following steps:
(1) Presetting non-woven fabrics: treating the non-woven fabric by a needle plate type heat setting machine, and presetting for 40-50s at 180-220 ℃ to obtain the pre-set non-woven fabric;
(2) Calendering pretreatment: calendering the pre-set non-woven fabric by adopting a calender, wherein the surface linear speed of the friction roller and the fabric speed ratio are (1-3): 1, obtaining a calendared non-woven fabric, wherein the temperature is 50-70 ℃ and the time is 50-70 s;
(3) Taking 500-700 parts by mass of water, adding 1-4 parts by mass of dispersing agent into the water, stirring the mixture for 1-3min at a rotating speed of 100-200r/min, adding 10-15 parts by mass of photocatalyst and 20-60 parts by mass of active carbon, and stirring the mixture for 20-40min at a rotating speed of 2000-3000r/min to obtain photocatalyst-active carbon dispersion liquid;
(4) Adding 100-200 parts of adhesive, 3-5 parts of essence and 50-60 parts of filler into the photocatalyst-active carbon dispersion liquid prepared in the step (3) according to parts by mass, and stirring at a rotating speed of 200-300r/min for 10-20min to obtain a non-woven fabric finishing liquid;
(5) The calendered non-woven fabric prepared in the step (2) is prepared according to a bath ratio of 1g: (40-60) mL immersing the non-woven fabric finishing liquid prepared in the step (4), stirring for 10-20min at a rotating speed of 100-200r/min, taking out, drying at 70-90 ℃ to obtain primary immersed non-woven fabric, and re-treating the primary immersed non-woven fabric according to a bath ratio of 1g: (40-60) mL immersing the non-woven fabric finishing liquid prepared in the step (4), stirring for 10-20min at a rotating speed of 100-200r/min, taking out, and drying at 70-90 ℃ to obtain impregnated non-woven fabric;
(6) Calendering and finishing: and (3) calendaring the impregnated non-woven fabric obtained in the step (5) by adopting a calendaring machine, wherein the surface linear speed of the friction roller and the fabric speed ratio are (1-3): 1, the temperature is 50-70 ℃ and the time is 50-70s, and the environment-friendly decorative material is obtained.
The dispersing agent is one of polyethylene glycol 200 and polyethylene glycol 400.
The filler is one or a mixture of two or more of kaolin, light calcium carbonate, heavy calcium carbonate and talcum powder; preferably, the filler is prepared from heavy calcium carbonate and talcum powder according to the mass ratio of (2-4): (5-7) mixing.
The adhesive is any one of an organic adhesive and an inorganic adhesive; preferably, the binder is an inorganic binder silica sol.
The non-woven fabric has poor dimensional stability due to the self-loose structure, and the subsequent heat treatment process is influenced, so that the non-woven fabric can maintain good dimensional stability in the high-temperature baking process, and the non-woven fabric is subjected to pre-shaping treatment before finishing the coating. The pre-shaping treatment greatly reduces the longitudinal and transverse shrinkage, especially the longitudinal direction, of the spun-laced base fabric, which also shows that the pre-shaping treatment improves the dimensional stability of the base fabric.
Although the dimensional stability of the spun-laced base fabric is improved after the pre-shaping, the surface evenness of the base fabric is still poor, so that the spun-laced base fabric after the pre-shaping needs to be subjected to calendaring finishing. The base cloth after calendaring finishing has a compact structure and small gaps among fibers, so that slurry is not easy to penetrate into the spun-laced base cloth when subsequent coating finishing is performed, and the smooth surface of the base cloth can also ensure the smoothness of a coating film.
And immersing the non-woven fabric subjected to shaping and calendaring pretreatment into the prepared non-woven fabric finishing liquid, fully immersing the pretreated non-woven fabric into the finishing liquid, drying, forming a film on the surface, and performing calendaring treatment again to obtain the environment-friendly decorative material. The non-woven fabric finishing liquid prepared by the invention mostly adopts inorganic materials, only the dispersing agent adopts polyethylene glycol dispersing agent, and the polyethylene glycol is easily degraded into carbon dioxide and water by the catalyst and does not pollute the environment, so the non-woven fabric wallpaper prepared by the invention is environment-friendly and does not harm the health of human bodies, and is an environment-friendly decorative material.
Firstly, the photocatalyst and the activated carbon are mixed, so that the activated carbon and the photocatalyst are mutually adsorbed, the activated carbon has extremely strong adsorptivity, and can absorb harmful gases such as formaldehyde and the like released by a wall body, thereby facilitating the degradation of the photocatalyst; in addition, the active carbon has extremely strong conductivity, can conduct photo-generated electrons, reduce the recombination rate of photo-generated electrons and holes, strengthen the catalytic capability of the photocatalyst, and greatly improve the efficiency of catalyzing and degrading harmful gases by the synergistic effect of the photo-generated electrons and the holes. According to the invention, silica sol is used as an adhesive, when the silica solution loses moisture, monomer silicic acid is gradually polymerized into high-polymer silica gel, and colloid molecules are increased along with evaporation of the moisture, so that a very stable silica bond coating film is finally formed, and the problem that the coating film is degraded by a photocatalyst, so that the coating film is aged and falls off is avoided. In addition, the silica bond coating film is compact and hard, does not generate static electricity, is difficult to adhere various dust in the air, has strong pollution resistance, and has obviously better water resistance and heat resistance than organic coating. In addition, the nano-scale silica particles in the silica sol are easy to be adsorbed by the activated carbon, so that a layer of silica protective film is formed on the surface of the photocatalyst-activated carbon particles, the contact between the photocatalyst and non-woven fabric fibers is reduced, the non-woven fabric is prevented from being aged by the photocatalyst, and the service life of the obtained environment-friendly decorative material is prolonged.
The invention further adopts the blending of the heavy calcium carbonate and the talcum powder as the finishing liquid filler, the heavy calcium carbonate can improve the whiteness and the opacity of the coating film, improve the ink absorbability, and has low price, but the fluidity of the coating is lower. Heavy calcium carbonate has the great advantage of reducing the viscosity of the slurry, improving the fluidity of the finishing liquid and preventing the coating from being too thick after the non-woven fabric is soaked. The talcum powder has good fiber covering capability, and can improve whiteness, smoothness and opacity of a coating substrate; has good rheological property and stability. The two are mixed for use, so that the combination capability of the filler and the non-woven fabric fiber is improved, the viscosity of the finishing liquid is reduced, and the cost is reduced. In addition, the addition of the filler further enhances the wear resistance and flame retardant capability of the non-woven fabric, can reduce contact between the photocatalyst and non-woven fabric fibers, and is synergistic with silica sol, so that the service life of the wallpaper is prolonged. Talc powder contains MgO/SiO as main ingredient 2 MgO-SiO is also formed with silica during dehydration of silica sol 2 The structure of SiO-OSi enhances the stability of the film and is not easy to fall off.
Still further, since the conventional photocatalyst is mostly an ultraviolet responsive photocatalyst or has an extremely low utilization ratio of visible light, its use has a great limitation. The invention further prepares a novel photocatalyst which not only has the property of visible light response, but also has extremely strong thermocatalytic capability and photo-thermal synergy, and has extremely strong capability of degrading pollutants by visible light at room temperature.
The preparation method of the photocatalyst comprises the following steps:
s1, adding 10-20 parts of ammonium meta-molybdate and 1.5-11 parts of modifier into 280-320 parts of water according to parts by weight at 75-85 ℃ and stirring for 5-10min at a rotating speed of 100-200r/min to obtain a precursor solution;
s2, adding 4-6 parts of 65-68wt% nitric acid into the precursor solution at the speed of 1-2mL/min at the temperature of 75-85 ℃ according to the parts by weight, stirring for 60-120min at the speed of 100-200r/min, centrifuging for 3-5min at the speed of 4000-8000r/min, taking precipitate, flushing with water and absolute ethyl alcohol for 3 times respectively, and finally drying the obtained solid at the temperature of 50-70 ℃ for 8-12h to obtain the photocatalyst.
The modifier is one or two of polyethylene glycol 400 and sodium ethylenediamine tetraacetate; preferably, the modifier is formed by mixing polyethylene glycol 400 and sodium ethylenediamine tetraacetate according to the mass ratio of (1-10) to (0.5-1).
The invention adopts ethylenediamine tetraacetate to chelate the meta-molybdate ion, controls the crystal growth direction, and uses polyethylene glycol to disperse the generated hydrated molybdenum trioxide so as to avoid generating large clusters, and the two synergistically regulate the morphology of the hydrated molybdenum trioxide and increase the surface area of the hydrated molybdenum trioxide. The photocatalyst prepared by the invention is hydrated molybdenum oxide, has a band gap of 2.8-3.0eV, can directly absorb visible light and can catalyze and degrade pollutants. In addition, due to the fact that crystal water is introduced, crystal lattice distortion is generated in molybdenum trioxide, jahne-Teller effect is formed, jahne-Teller distortion increases Lewis acid site, oxygen adsorption and activation are promoted, thermal catalytic performance of hydrated molybdenum trioxide is greatly improved, meanwhile, crystal water and molybdenum trioxide coordinate, energy required by electrons to transition from crystal water to molybdenum trioxide is smaller than energy required by electrons to transition from molybdenum to oxygen in molybdenum trioxide during photoexcitation, energy required by photoexcitation electron transition is reduced, and photo-generated electron-hole can be generated under excitation of visible light with longer wavelength, and utilization rate of visible light is improved. Due to the photo-thermal synergistic effect caused by structural water, the prepared hydrated molybdenum oxide has the property of degrading pollutants in indoor natural light environment. The degradation reaction is simple, low in cost, energy-saving and space-saving, and can be suitable for cleaning indoor or limited space.
The invention has the beneficial effects that:
according to the invention, silica sol is adopted as an adhesive, heavy calcium carbonate and talcum powder are mixed to be used as finishing liquid filler, so that the wear resistance and flame retardant capability of the non-woven fabric are enhanced, the stability of the film is enhanced, the contact between a photocatalyst and non-woven fabric fibers can be reduced, and the service life of the environment-friendly decorative material is prolonged.
The invention adopts the mixed use of the activated carbon and the photocatalyst, thereby enhancing the catalytic capability of the photocatalyst of the environment-friendly decorative material, greatly improving the efficiency of catalyzing and degrading harmful gases and improving the antistatic capability of the photocatalyst.
The photocatalyst-hydrated molybdenum trioxide with the pollutant degradation performance under the indoor natural light environment is prepared by an extremely simple method, and polyethylene glycol 400 and sodium ethylenediamine tetraacetate are used as modifiers, so that the gas pollutant catalytic degradation capability is further enhanced.

Test example 1
The common pollutant gas removal rate of each environment-friendly decorative material prepared in the examples and the comparative examples is measured, and the test method of the common pollutant gas removal rate is referred to QB/T2761-2006, method for measuring the purification effect of indoor air purification products. Sample 1m 2 The environment-friendly decorative material prepared by the embodiments; the volume of the test bin is 0.9m multiplied by 1.85m, and the temperature is 26 ℃; the light source is a xenon lamp, and the average illumination intensity is 500Lux.
The formaldehyde concentration (mg/m) of each initial test chamber was recorded 3 ) Total volatile organic matter concentration (mg/m) 3 ) Benzene concentration (mg/m) 3 ) And the formaldehyde concentration (mg/m) of each group of 72h test chambers was recorded 3 ) Total volatile organic matter concentration (mg/m) 3 ) Benzene concentration (mg/m) 3 ) The decrease rate (%) of each contaminant was calculated;
wherein formaldehyde reduction rate (%) =1- (formaldehyde concentration of 72h test chamber/formaldehyde concentration of initial test chamber) ×100%;
total volatile organic matter reduction rate (%) =1- (total volatile organic matter concentration of 72h test chamber/total volatile organic matter concentration of initial test chamber) ×100%;
benzene reduction (%) =1- (benzene concentration in 72h test chamber/benzene concentration in initial test chamber) ×100%.
Table 1: gas pollutant removal rate test for environment-friendly decorative material
As can be seen from table 1, example 1 shows the lowest removal rate of formaldehyde, total volatile organic compounds and benzene, because the environment-friendly decorative material prepared in example 1 only contains activated carbon, and certain volatile harmful gases are adsorbed by virtue of the adsorption effect of the activated carbon, and when the activated carbon is saturated in adsorption, namely reaches equilibrium, the amount of volatile harmful gases in the test bin is no longer reduced. The clearance rate of the example 2 to the gas pollutants is obviously higher than that of the example 1, because the environment-friendly decorative material prepared in the example 2 is added with the hydrated molybdenum trioxide, the band gap of the hydrated molybdenum oxide photocatalyst prepared in the invention is 2.8-3.0eV, and the hydrated molybdenum oxide photocatalyst can directly absorb visible light and catalyze and degrade the pollutants. In addition, due to the fact that crystal water is introduced, crystal lattice distortion is generated in molybdenum trioxide, jahne-Teller effect is formed, jahne-Teller distortion increases Lewis acid site, oxygen adsorption and activation are promoted, thermal catalytic performance of hydrated molybdenum trioxide is greatly improved, meanwhile, crystal water and molybdenum trioxide coordinate, energy required by electrons to transition from crystal water to molybdenum trioxide is smaller than energy required by electrons to transition from molybdenum to oxygen in molybdenum trioxide during photoexcitation, energy required by photoexcitation electron transition is reduced, and photo-generated electron-hole can be generated under excitation of visible light with longer wavelength, and utilization rate of visible light is improved. Due to the photo-thermal synergistic effect caused by structural water, the prepared hydrated molybdenum oxide has the property of degrading pollutants in indoor natural light environment. The gas pollutant removal rate of the embodiment 3 is obviously higher than that of the embodiment 2, because the sodium ethylenediamine tetraacetate and the polyethylene glycol are added as the modifier in the process of preparing the hydrated molybdenum trioxide, the ethylenediamine tetraacetate can chelate meta-molybdate ions, the crystal growth direction of the molybdenum trioxide is controlled in the nucleation and crystallization process, flower-shaped clusters consisting of nano wires are prepared, but the prepared hydrated molybdenum trioxide is low in dispersibility due to the fact that the nano wires are easy to cluster, the surface area is small, and the exposed Lewis acid sites are less, so that the polyethylene glycol is further used for enhancing the dispersibility of the water and the molybdenum trioxide nano wires, the large clusters are avoided being generated, the morphology of the water and the molybdenum trioxide nano wires is regulated and controlled in a coordinated manner, the surface area is increased, more Lewis acid sites are exposed, and the pollutant degradation capability of the molybdenum trioxide nano wires is greatly enhanced. This is also demonstrated by the reduced ability of disodium ethylenediamine tetraacetate or polyethylene glycol alone to control hydrated molybdenum trioxide in examples 4 and 5 to degrade gaseous pollutants.
Test example 2
And testing the influence of light irradiation on the ageing degree of the prepared environment-friendly decorative material.
Reference GB/T3923.1-2013 section 1 of textile fabric tensile properties: determination of breaking Strength and elongation at break the breaking strength difference before and after ultraviolet ageing of the environmental protection decorative materials prepared in examples and comparative examples was determined in the test method. The textile fabric tensile testing machine is adopted, the tensile speed is 20mm/min, and the pretension is 2N.
Sample preparation: cutting 20 pieces of samples with the size of 50mm multiplied by 200mm from the environment-friendly decorative materials prepared in the examples and the comparative examples, and aging 10 pieces of samples for 72 hours under an ultraviolet lamp with the light intensity of 500Lux to obtain experimental samples; the other 10 blocks were left without ultraviolet irradiation for 72 hours to obtain blank samples. The test results were obtained as an average of 10 samples, and the difference in breaking strength between the samples before and after ultraviolet aging=the average of breaking strength of the blank samples-the average of breaking strength of the test samples.
The test results are shown in Table 2.
Table 2: breaking strength difference test result of samples before and after ultraviolet aging
| Breaking strength difference/kN | |
| Example 1 | 0.2 |
| Example 3 | 0.3 |
| Comparative example | 2.1 |
As can be seen from Table 2, the environmental-friendly decorative materials using silica sol as the binder in each example still maintained good tensile strength after irradiation with ultraviolet rays for 72 hours, while the comparative examples used polyvinyl alcohol as the binder, and the tensile properties were drastically reduced after irradiation with ultraviolet rays. When the silicon solution loses moisture, monomer silicic acid gradually polymerizes into high-polymer silica gel, and colloid molecules are increased along with the evaporation of the moisture, so that a very stable silica bond coating film is finally formed, and the problem that the coating film is degraded by a photocatalyst, so that the coating film is aged and falls off is avoided. In addition, the silica bond coating film is compact and hard, does not generate static electricity, is difficult to adhere various dust in the air, has strong pollution resistance, and has obviously better water resistance, heat resistance and mechanical property than the organic coating. In addition, a layer of coating film can be formed on the surface of the photocatalyst-activated carbon particles in the dehydration process of the silica sol, so that the contact between the photocatalyst and the non-woven fabric is reduced, and the non-woven fabric is prevented from being aged by active free radicals generated by the photocatalyst. While organic binders, typified by polyvinyl alcohol, are clearly unsuitable for film-forming coatings containing photocatalysts. The active free radical generated by the photocatalyst can decompose the organic adhesive and further damage the non-woven fabric fiber, so that the service life of the prepared environment-friendly decorative material is shortened.
