The invention belongs to the field of building decoration materials, and relates to a soft porcelain material with ultraviolet blocking and toxic gas removing functions and a preparation method thereof.
Background
The soft porcelain is a novel flexible planar decorative material, is obtained by molding and processing water-based polymer emulsion and inorganic substances such as cement, soil, quartz sand or mineral powder and the like, and is an ecological environment-friendly building material. The appearance of the soft porcelain is exactly like the porcelain, but the soft porcelain lacks the ice-cold, heavy and fragile texture of the traditional ceramic material, has the characteristics of light weight, thin body, water and air permeability, natural color, various patterns, flexibility, elasticity and the like, is easy to cut and paste, has low cost and convenient construction, is suitable for building decoration of external walls, internal walls, ground and the like, and greatly enriches and beautifies the living and working environments of people.
With the development of the technology, people develop various and colorful soft porcelain materials such as stone imitation materials, leather imitation patterns, wood imitation grains and the like in succession, and the soft porcelain materials meet the requirement of building nature returning. Along with the improvement of living standard of people, the requirements of people on living environment are higher and higher, such as the requirements of odor elimination, bacteriostasis, antibiosis, warmness, comfort and the like. There have been many studies on soft porcelain in the prior art,
For example, patent application with publication number CN104030613A discloses a preparation method of a soft porcelain material, the soft porcelain is prepared by mixing an organic material and an inorganic material, and has waterproofness, flexibility and ultra-long weather resistance, the preparation process is simple, and a high-temperature firing link is not required, however, the soft porcelain prepared by the application has a conventional process, does not have special functionality, and cannot meet the requirements of people on living environment.
The patent application with the publication number of CN104277317A discloses a preparation method of a phase-change temperature-regulating soft ceramic material, and on the basis that the prepared soft ceramic material has better surface finish and better stain resistance, the performance indexes of the material are more uniform and more stable, so that the prepared soft ceramic material has excellent tensile strength and shear strength, and the comprehensive performances of water resistance, flame retardance, acid and alkali corrosion resistance, thawing resistance, earthquake resistance, crack resistance and the like. But the nano material used by the substance undoubtedly increases the cost of the soft porcelain.
The patent application with the publication number of CN104446177A discloses a method for preparing a soft porcelain archaized brick by utilizing manganese slag tailings, wherein manganese slag tailings powder is mixed with quartz sand, cement, emulsion and water according to a corresponding proportion to prepare slurry with certain fluidity, and then the slurry is prepared into soft porcelain.
The invention mainly aims to solve the problems in the prior art, such as complex preparation process, single function, high cost, uneven mechanical properties of soft porcelain materials and the like.
According to the multilayer structure of the rectorite, the natural rectorite has better capability of absorbing and capturing gas, however, the natural rectorite in China mostly belongs to calcium-based rectorite, Ca 2+ has stronger adsorption force with the surface of the rectorite particles, and a bilayer formed in water is thinner than Na +, so the expansion factor is low, the dispersibility is poor, and the reaction activity is small, and therefore, the functional particles are difficult to load on the rectorite in the reaction process.
The titanium dioxide can decompose toxic gas such as formaldehyde under photocatalysis, and has an antibacterial function, the soft porcelain material is prepared by mixing inorganic and organic materials, and fine pores exist on the surface of the soft porcelain material, so that the soft porcelain layer has good air permeability, and in addition, the titanium dioxide has certain blocking and absorbing functions on ultraviolet rays.
The invention aims to prepare a soft porcelain material with ultraviolet blocking and toxic gas removing functions, rectorite is selected, rectorite is modified by a certain means, and then titanium dioxide is attached to the rectorite to prepare the soft porcelain material.
Disclosure of Invention
In order to solve the problems in the prior art and prepare the soft porcelain material with ultraviolet blocking and toxic gas removing functions, the invention adopts the following method.
Because the rectorite in China mostly belongs to calcium-based rectorite, and the dispersibility of the calcium-based rectorite in a solvent is poor, which is not beneficial to subsequent reactions, firstly, the invention modifies the rectorite and adopts a cation exchange method to convert the calcium-based rectorite into the sodium-based rectorite.
The method comprises the steps of putting calcium-based rectorite into a certain amount of deionized water, adding a proper amount of NaCl, mechanically stirring to uniformly disperse the calcium-based rectorite, heating the dispersion, adding a buffer solution to adjust the pH value to 8-11, continuously stirring, cooling and filtering, washing the filtered material with water for a plurality of times to remove impurity ions, and drying the filtered filter cake to obtain the sodium-based rectorite.
the heating temperature is 80-100 ℃.
The buffer solution is Na 2 CO 3 and NaHCO 3 solution.
The bilayer formed by sodium-based rectorite in solution is thinner and has a lower expansion factor than Na +, so the dispersibility is better than that of calcium-based rectorite, which is beneficial to the reaction.
Because a large amount of organic materials are used in the preparation process of the soft porcelain, in order to ensure that the rectorite has better dispersibility and improve the uniformity of the performance of the soft porcelain material, the sodium-based rectorite obtained by the method is dispersed in the silicone-acrylic emulsion, and in order to further improve the dispersibility of the rectorite, the rectorite is organically modified. Organic modification mainly utilizes the negative charge of a montmorillonite layer of the rectorite, can adsorb organic polar molecules, and selects a proper organic modifier to organically modify the rectorite. The method mainly comprises the following steps:
And (2) putting the prepared sodium-based rectorite into a quantitative silicone-acrylic emulsion, adding a proper amount of alkyl trimethyl ammonium bromide, mechanically stirring to uniformly disperse the sodium-based rectorite, heating the dispersion, continuously stirring, and cooling to obtain the organic modified rectorite.
The alkyl trimethyl ammonium bromide is one or more of dodecyl trimethyl ammonium bromide, hexadecyl trimethyl ammonium bromide and octadecyl trimethyl ammonium bromide.
The heating temperature is 80-100 ℃.
In order to introduce the nano titanium dioxide, the invention adopts the hydrolysis of titanium n-butyl titanate Ti (OBu) 4 to prepare the nano titanium dioxide, the nano titanium dioxide prepared by the hydrolysis method can be loaded on rectorite, and simultaneously can be more uniformly dispersed in a silicone-acrylic emulsion after being organically modified according to rectorite, so that the slurry for preparing the soft porcelain material is uniformly dispersed, and the mechanical property of the soft porcelain material is further improved, and the specific hydrolysis method is as follows:
Slowly adding a certain amount of n-butyl titanate Ti (OBu) 4 into 1.0mol/L hydrochloric acid solution at room temperature, stirring, adjusting the pH value to about 1.5 by using NaOH solution after reacting for a period of time, continuously stirring until the solution is colorless and transparent, adjusting the pH value to 6-9 by using NaOH solution to obtain n-butyl titanate Ti (OBu) 4 hydrolysis solution, adding the obtained n-butyl titanate Ti (OBu) 4 hydrolysis solution into silicone-acrylic emulsion of organic modified rectorite, and continuously stirring to obtain 2 nano composite material for later use.
The rectorite/TiO 2 nano composite material is organically modified, and has excellent dispersing performance in silicone-acrylic emulsion, and the prepared rectorite/TiO 2 nano composite material has no layering phenomenon in the silicone-acrylic emulsion.
The soft porcelain material is obtained by taking the obtained rectorite/TiO 2 nano composite material as a raw material and mixing, stirring, reversing a mold, curing and forming other materials, and the specific steps are as follows:
Weighing 20-30 parts of the rectorite/TiO 2 nano composite material silicone-acrylate emulsion and 1-3 parts of inorganic pigment in parts by weight, adding into a stirring kettle, and uniformly stirring to obtain a mixed emulsion material;
Adding 2-10 parts of flame retardant, 5-30 parts of cement, 25-35 parts of quartz sand and 1-3 parts of coupling agent into a kneader, and uniformly mixing to obtain mixed powder
And adding the obtained mixed powder into the obtained mixed emulsion material, uniformly stirring, injecting into a mold, drying at 90-130 ℃ for 2-4 hours, and demolding to obtain the soft porcelain material with ultraviolet blocking and toxic gas removing functions.
