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 environment. In the aspect of indoor decoration, because some toxic substances such as formaldehyde and the like are generally volatilized from traditional wall building materials, paints and the like to harm human health, the development of wallpaper conforms to the environmental protection concept, and the wallpaper also has the advantages of convenience in use, various styles, low price and the like, and is challenging the status of traditional wall decoration materials in indoor decoration.
At present, wallpaper in the market has various varieties, such as pure paper wallpaper, fabric wallpaper, metal wallpaper, natural material wallpaper, PVC wallpaper and the like, and although the pure paper wallpaper has respective advantages, the wallpaper also has some disadvantages, such as pure paper wallpaper has good environmental protection performance, but has the disadvantages of water resistance, moisture resistance, scrubbing resistance and the like, the wallpaper is not easy to be cleaned, the requirement on construction technology is high, and obvious seams are easily generated once the wallpaper is not operated properly; although the PVC wallpaper has the advantages of sound absorption effect, high cost performance and easiness in cleaning, the PVC wallpaper is poor in air permeability and not environment-friendly; fabric wallpaper, like silk wallpaper and satin wallpaper, cannot be widely popularized due to the defects of high price, difficulty in cleaning and the like; although natural wallpaper made of natural materials has rich local soil smell and is natural and simple, the durability and the fire resistance are poor. Therefore, the green environment-friendly non-woven wallpaper is unique. The non-woven wall paper is a new high-grade wall decoration material made up by using natural fibre of cotton and hemp, etc. or synthetic fibre of polyester fibre and acrylic fibre, and adopting the processes of non-woven forming, resin-coating or hot-rolling gluing and printing, etc. in turn. The air-permeable fabric is not easy to break and age, has soft texture, certain moisture resistance, air permeability and the like, and is favored by more and more consumers.
At present, the research on the non-woven fabric wallpaper mostly focuses on the fields of wear resistance, antibiosis, mildew prevention, 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 fabric wallpaper. The improvement of the mechanical property of the fabric is usually from the viewpoint of improving the non-woven fabric material or adding inorganic filler, is environment-friendly and is not easy to generate substances harmful to human bodies, however, the improvement of the chemical property of the fabric is usually realized by using a large amount of organic solvents, is not environment-friendly and is harmful to human bodies. Especially when the photocatalyst material is applied to formaldehyde removal of the photocatalyst material, the organic solvent is used as the film forming agent, the dispersibility and the immobilization time of the photocatalyst material on the non-woven fabric are enhanced, the photocatalyst material is easily decomposed by the photocatalyst material 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 shortened. The photocatalyst material is a material which can rarely degrade formaldehyde under the condition of room temperature illumination in the prior art, and has the defects that the catalytic degradation capability under visible light is poor, and the wallpaper is easily damaged by generated oxidation free radicals, so that the research direction of improving the degradation capability under visible light and fixing the photocatalyst material on the wallpaper can not damage the wallpaper is very meaningful.
CN 110373915A discloses an environment-friendly non-woven fabric wallpaper capable of absorbing and degrading formaldehyde and a preparation process thereof, wherein water-based acrylic acid is used as an adhesive, nano manganese dioxide is fixed on the surface of the non-woven fabric, the adhesive and the non-woven fabric are greatly corroded due to the strong oxidizability of the manganese dioxide, the manganese dioxide is easily inactivated due to the reaction of the manganese dioxide and formaldehyde, and the service life of the prepared non-woven fabric is relatively short.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides an environment-friendly decorative material and a preparation method thereof.
A preparation method of an environment-friendly decorative material comprises the following steps:
(1) presetting non-woven fabrics: treating the non-woven fabric by using a needle plate type heat setting machine, and presetting at the temperature of 180-220 ℃ for 40-50s to obtain a preset non-woven fabric;
(2) calendering pretreatment: and (3) calendering the pre-shaped non-woven fabric by adopting a calender, wherein the surface linear speed and the fabric speed ratio of the rubbing roll are (1-3): 1, obtaining the calendered non-woven fabric at the temperature of 50-70 ℃ for 50-70 s;
(3) taking 700 parts by mass of 500-fold water, adding 1-4 parts by mass of a dispersing agent, stirring at a rotating speed of 100-fold 200r/min for 1-3min, adding 10-15 parts by mass of a photocatalyst and 20-60 parts by mass of activated carbon, and stirring at a rotating speed of 2000-fold 3000r/min for 20-40min to obtain a photocatalyst-activated carbon dispersion liquid;
(4) adding 200 parts by mass of 100-plus-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), and stirring at the rotating speed of 300r/min for 10-20min to obtain non-woven fabric finishing liquid;
(5) and (3) calendering the non-woven fabric prepared in the step (2) according to a bath ratio of 1 g: (40-60) mL of the non-woven fabric finishing liquid prepared in the step (4) is immersed in the non-woven fabric finishing liquid, the non-woven fabric finishing liquid is stirred for 10-20min at the rotating speed of 100-200r/min, the non-woven fabric is taken out and dried at the temperature of 70-90 ℃ to obtain a primary impregnated non-woven fabric, and the primary impregnated non-woven fabric is again immersed in the non-woven fabric finishing liquid according to the bath ratio of 1 g: (40-60) soaking the obtained product in mL into the non-woven fabric finishing liquid prepared in the step (4), stirring at the rotating speed of 100-200r/min for 10-20min, taking out, and drying at the temperature of 70-90 ℃ to obtain a soaked non-woven fabric;
(6) and (3) calendering and finishing: and (3) calendering the impregnated non-woven fabric obtained in the step (5) by adopting a calender again, wherein the surface linear speed and the fabric speed ratio of the rubbing roll are (1-3): 1, the temperature is 50-70 ℃, and the time is 50-70s, so as to obtain the environment-friendly decorative material.
The dispersant 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 ground 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, influences the subsequent heat treatment process, and is pre-shaped before the coating is finished in order to ensure that the non-woven fabric can keep good dimensional stability in the high-temperature baking process. The pre-setting treatment greatly reduces the longitudinal and transverse shrinkage of the spunlace base fabric, particularly the longitudinal direction, which also shows that the pre-setting treatment improves the dimensional stability of the base fabric.
Although dimensional stability of the spunlace base fabric is improved after pre-setting, the surface flatness of the base fabric is still poor, so that calendering treatment needs to be carried out on the pre-set spunlace base fabric. The base fabric after calendering finishing has a compact structure and relatively small gaps among fibers, so that slurry is not easy to permeate into the spunlace base fabric during subsequent coating finishing, and the smooth surface of the coating film can be ensured.
And then, immersing the non-woven fabric subjected to shaping and calendaring pretreatment into the prepared non-woven fabric finishing liquid, fully soaking the pretreated non-woven fabric into the finishing liquid, drying, forming a film on the surface, and calendaring again to obtain the environment-friendly decorative material. Most of the non-woven fabric finishing liquid prepared by the invention adopts inorganic materials, only the dispersant adopts polyethylene glycol dispersant, and the polyethylene glycol is easy to be degraded into carbon dioxide and water by a 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 human health, 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, and the activated carbon has extremely strong adsorbability, can absorb harmful gases such as formaldehyde released by a wall body and the like, and is convenient for the degradation of the photocatalyst; in addition, the activated carbon has extremely strong conductivity, can conduct photoproduction electrons, reduces the recombination rate of photoproduction electrons and holes, enhances the catalytic capability of the photocatalyst, and greatly improves the efficiency of catalytic degradation of harmful gases due to the synergistic effect of the photoproduction electrons and the holes. According to the invention, the silica sol is used as the adhesive, when the silicon solution loses moisture, the monomer silicic acid is gradually polymerized into high polymeric silica gel, the colloidal molecules are enlarged along with the evaporation of the moisture, and finally, a stable silicon-oxygen bond coating film is formed, so that 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 silicon-oxygen bond coating is compact and hard, does not generate static electricity, is difficult to adhere various dust in the air, has strong pollution resistance, and has water resistance and heat resistance obviously superior to those of organic coatings. In addition, the nano-scale silicon dioxide particles in the silica sol are easily adsorbed by the active carbon, so that a layer of silicon dioxide protective film is formed on the surface of the photocatalyst-active carbon particles, the contact between the photocatalyst and the non-woven fabric fiber is reduced, the photocatalyst is prevented from aging the non-woven fabric, 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 filler of the finishing liquid, the heavy calcium carbonate can improve the whiteness and the opacity of a coating film and improve the absorptivity of the printing ink, and the price is low, but the fluidity of the coating is lower. The heavy calcium carbonate also has the advantages of reducing the viscosity of the slurry and improving the fluidity of finishing liquid, so that the coating can not be too thick after the non-woven fabric is soaked. Sliding deviceThe stone powder has good fiber covering capacity, and can improve the whiteness, smoothness and opacity of a coating base material; has good rheological property and stability. The two are mixed for use, so that the binding capacity of the filler and the non-woven fabric fiber is increased, the viscosity of the finishing liquid is reduced, and the cost is reduced. In addition, the wear resistance and the flame retardant capability of the non-woven fabric are further enhanced by adding the filler, the contact between the photocatalyst and the non-woven fabric fibers can be reduced, and the service life of the wallpaper is prolonged by cooperating with the silica sol. The main component of the talcum powder is MgO-SiO2In the dehydration process of silica sol, MgO. SiO is formed with silica2The structure of-SiO-OSi enhances the stability of the film and is not easy to fall off.
Still further, since most of the conventional photocatalysts are ultraviolet-responsive photocatalysts or have a very low utilization rate of visible light, their 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 thermal catalytic capability, photo-thermal synergy and 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 paramolybdate and 1.5-11 parts of modifier into 320 parts of 280-one-waste water at 75-85 ℃ by mass, and stirring at the rotating speed of 100-one-waste 200r/min for 5-10min to obtain a precursor solution;
s2, adding 4-6 parts by mass of 65-68 wt% nitric acid into the precursor solution at a speed of 1-2mL/min at a temperature of 75-85 ℃, stirring at a rotation speed of 100-.
The modifier is one or a mixture of polyethylene glycol 400 and sodium ethylene diamine tetracetate; preferably, the modifier is prepared by mixing polyethylene glycol 400 and sodium ethylene diamine tetracetate according to a mass ratio of (1-10) to (0.5-1).
According to the invention, ethylene diamine tetraacetic acid is adopted to chelate metapholybdate ions, the crystal growth direction of the metamolybdate ions is controlled, the hydrated molybdenum trioxide generated by polyethylene glycol dispersion is used to avoid the generation of large clusters, the morphology of the hydrated molybdenum trioxide is cooperatively regulated by the ethylene diamine tetraacetic acid and the polyethylene glycol, and the surface area of the hydrated molybdenum trioxide is increased. The photocatalyst prepared by the invention is hydrated molybdenum oxide, the band gap of the photocatalyst is 2.8-3.0eV, and the photocatalyst can directly absorb visible light and catalyze and degrade pollutants. In addition, due to the introduction of crystal water, the molybdenum trioxide generates lattice distortion to form Jahne-Teller effect, the Jahne-Teller distortion increases Lewis acid site sites to promote the adsorption and activation of oxygen, the thermal catalytic performance of hydrated molybdenum trioxide is greatly improved, meanwhile, the crystal water and the molybdenum trioxide coordinate, and due to the fact that water is an electron-rich ligand, the energy required by electrons to jump from the crystal water to the molybdenum trioxide is less than that required by electrons in the molybdenum trioxide to jump from the molybdenum to the oxygen during light excitation, the energy required by light excitation electron jump is reduced, and the photo-generated electrons-holes can be generated under the excitation of longer-wavelength visible light, and the utilization rate of the visible light is improved. Due to the photo-thermal synergistic effect caused by the structural water, the prepared hydrated molybdenum oxide has the performance of degrading pollutants in an indoor natural light environment. The degradation reaction is simple, low in cost, energy-saving and space-saving, and is suitable for indoor or limited space cleaning.
The invention has the beneficial effects that:

Test example 1
The common pollutant gas removal rate of each environment-friendly decorative material prepared in the examples and the comparative examples is determined, and the test method of the common pollutant gas removal rate refers to QB/T2761-2006 method for determining the purification effect of indoor air purification products. The sample was 1m2The 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 500 Lux.
Record the concentration of formaldehyde (mg/m) for each set of initial test chambers3) Total volatile organic concentration (mg/m)3) Benzene concentration (mg/m)3) And recording the formaldehyde concentration (mg/m) of each group of 72h test chambers3) Total volatile organic concentration (mg/m)3) Benzene concentration (mg/m)3) Calculating the reduction rate (%) of each pollutant;
wherein, the formaldehyde reduction rate (%) is 1- (formaldehyde concentration of 72h test chamber/formaldehyde concentration of initial test chamber) × 100%;
the total volatile organic matter reduction rate (%) is 1- (total volatile organic matter concentration of the 72h test chamber/total volatile organic matter concentration of the initial test chamber) × 100%;
the benzene reduction rate (%) × 1- (benzene concentration in 72h test chamber/benzene concentration in initial test chamber) × 100%.
Table 1: gas pollutant removal rate test of environment-friendly decorative material
As can be seen from table 1, the lowest removal rate of formaldehyde, total volatile organic compounds and benzene is shown in example 1, because the environment-friendly decorative material prepared in example 1 only contains activated carbon, and adsorbs certain volatile harmful gases by virtue of the adsorption effect of the activated carbon, when the activated carbon is saturated in adsorption, the balance is achieved, and the amount of the volatile harmful gases in the test chamber is not reduced any more. The removal rate of the gas pollutants in the embodiment 2 is obviously higher than that in the embodiment 1, because the hydrated molybdenum trioxide is added into the environment-friendly decorative material prepared in the embodiment 2, 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 pollutants. In addition, due to the introduction of crystal water, the molybdenum trioxide generates lattice distortion to form Jahne-Teller effect, the Jahne-Teller distortion increases Lewis acid site sites to promote the adsorption and activation of oxygen, the thermal catalytic performance of hydrated molybdenum trioxide is greatly improved, meanwhile, the crystal water and the molybdenum trioxide coordinate, and due to the fact that water is an electron-rich ligand, the energy required by electrons to jump from the crystal water to the molybdenum trioxide is less than that required by electrons in the molybdenum trioxide to jump from the molybdenum to the oxygen during light excitation, the energy required by light excitation electron jump is reduced, and the photo-generated electrons-holes can be generated under the excitation of longer-wavelength visible light, and the utilization rate of the visible light is improved. Due to the photo-thermal synergistic effect caused by the structural water, the prepared hydrated molybdenum oxide has the performance of degrading pollutants in an indoor natural light environment. The removal rate of the gas pollutants in the embodiment 3 is obviously higher than that in the embodiment 2, because sodium ethylene diamine tetracetate and polyethylene glycol are added as modifiers in the process of preparing the hydrated molybdenum trioxide, ethylene diamine tetracetate can chelate metapholybdate ions, and the crystal growth direction of the hydrated molybdenum trioxide is controlled in the process of nucleating and crystallizing the molybdenum trioxide, flower-shaped clusters consisting of nanowires are prepared, but the prepared hydrated molybdenum trioxide is low in dispersity and surface area and less in exposed Lewis acid sites due to the fact that the nanowires are easy to cluster, therefore, the dispersibility of the water and molybdenum trioxide nanowires is further enhanced by the polyethylene glycol, the large clusters are prevented from being generated, the shapes of the water and molybdenum trioxide nanowires are cooperatively regulated, the surface area of the hydrated molybdenum trioxide is increased, more Lewis acid sites are exposed, and the pollutant degradation capability of the hydrated molybdenum trioxide is greatly enhanced. This is also demonstrated by the fact that disodium ethylenediaminetetraacetate or polyethylene glycol alone, which regulates hydrated molybdenum trioxide, both have a reduced ability to degrade gaseous pollutants.
Test example 2
The influence of the light irradiation on the aging degree of the prepared environment-friendly decorative material is tested.
Reference GB/T3923.1-2013 part 1 of tensile Properties of textile fabrics: the difference between the breaking strength before and after ultraviolet light aging of the environment-friendly decorative material prepared in the examples and the comparative examples is measured by the test method of breaking strength and breaking elongation. A 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 material prepared in the embodiment and the comparative example, 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 UV irradiation for 72 hours to obtain blank samples. The test result is the average value of 10 samples, and the difference of the breaking strength of the samples before and after ultraviolet aging is the average value of the breaking strength of the blank sample-the average value of the breaking strength of the experimental sample.
The test results are shown in Table 2.
Table 2: test result of fracture strength difference of sample before and after ultraviolet aging
Differential breaking force/kN | |
Example 1 | 0.2 |
Example 3 | 0.3 |
Comparative example | 2.1 |
As can be seen from Table 2, the environmentally friendly decorative material using silica sol as the binder in each example still maintained a good tensile strength after being irradiated with ultraviolet for 72 hours, while the comparative example using polyvinyl alcohol as the binder sharply decreased the tensile strength after being irradiated with ultraviolet. The reason is that when the silicon solution loses moisture, monomer silicic acid is gradually polymerized into high polymer silica gel, colloid molecules are enlarged along with the evaporation of the moisture, and finally a stable silicon-oxygen bond coating film is formed, so that the problem that the coating film is degraded by a photocatalyst, so that the coating film is aged and falls off is solved. In addition, the silicon-oxygen bond coating is compact and hard, does not generate static electricity, is difficult to adhere various dust in the air, has strong pollution resistance, and has water resistance, heat resistance and mechanical property obviously superior to those of organic coatings. In addition, the silica sol can form a coating film on the surface of the photocatalyst-activated carbon particles in the dehydration process, 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 represented by polyvinyl alcohol are clearly not suitable for film-forming coatings containing a photocatalyst. The active free radicals generated by the photocatalyst can not only decompose the organic adhesive, but also further damage the non-woven fabric fibers, thereby shortening the service life of the prepared environment-friendly decorative material.
