Description

TECHNICAL FIELD

[0001] The present application relates to a kind of baking-free glazed decorative plate, in particular to a kind of large amount of solid waste baking-free glazed decorative plate and preparation method thereof. BACKGROUND

[0002] At present, the preparation of baking-free glazed decorative plate is to use fiber cement board, glass, stone or metal plate as substrate, and to coat glaze layer on the substrate. The glaze layer is usually made of inorganic powder mixed with resin material. However, the glaze layer has the problem of adhesion with the substrate. Therefore, the current standard requires the flat tensile bonding strength of the glaze layer with various substrates to be 0.5 MPa to 1.5 MPa. However, under the long-term environmental effect, with the aging of the resin adhesive, there are problems such as aging, cracking, peeling and falling off of the glaze layer.

[0003] The utility model discloses a baking-free glazed decorative plate, which includes a glaze layer, a shaping layer, a substrate layer and a fixing layer. The layers are coated with hot melt adhesive and pressed into shape. The material of the glaze layer is not specified, only that the glaze layer is placed on the gypsum layer, and the glaze layer and the shaping layer are connected by the gypsum. It can be seen that the glaze layer is a plate material, which is bonded to the shaping layer by the gypsum. Then, waterproof paint is coated on the side of the plate body. The utility model is essentially a multi-layer bonded board. The hot melt adhesive and the waterproof paint have the problem of aging. After the hot melt adhesive ages, the bonding will fail. The aging of the waterproof paint will cause water to enter the gypsum layer, resulting in the failure of the gypsum bonding due to moisture.

[0004] The manufacturing method of the baking-free sintering preparation of the stone-like decorative plate disclosed in CN104163614A is characterized by the following components: 50-80% of building waste, 10-35% of active magnesium oxide, 5-20% of magnesium chloride, 0.5-2% of color powder, 5-20% of water, 0.01-0.1% of boron oxide and 0.5-1% of curing agent. The above-mentioned building waste, active magnesium oxide, magnesium chloride, water and boron oxide are mixed and stirred uniformly to form a composite material. Then, the composite material is injected into a mold and vibrated to form. Finally, the product is demolded, dried and polished to become a stone material. However, the document does not specify what the so-called building waste is and what its composition is. There is no description or data support for the high bending resistance and shock resistance of the product. The unique surface treatment technology used in the manufacturing process is also not described in the document.

[0005] Paper mill lime mud is an industrial solid waste produced by paper industry, about 0.8-1 tons of lime mud solid waste is produced for every 1 ton of pulp paper, the main chemical components of lime mud are calcium carbonate, silicon dioxide and residual alkali, the pulp used for papermaking is mainly bagasse pulp, compared with wood pulp papermaking, the papermaking lime mud of bagasse pulp has the characteristic of high silicon dioxide content, and cannot be used for producing calcium carbonate like the papermaking lime mud of wood pulp, at present, can only be landfilled or used for flue gas treatment of thermal power, which not only causes waste of land resources and environmental pollution, but also wastes the resources of calcium carbonate and silicon dioxide in the lime mud. SUMMARY

[0006] The technical problem to be solved by the present application is to provide a large-mixing-amount multi-solid-waste unburned glaze decorative plate and a preparation method thereof.

[0007] The technical solution for solving the above technical problem is: a large-mixing-amount multi-solid-waste unburned glaze decorative plate is prepared by weighing materials in a certain weight ratio, adding water to stir to form a slurry in a factory, and pouring into a mold to form. The content of each component material is as follows: cement: 700-950 parts, silica ash: 80-160 parts, carbide slag powder: 90-120 parts, lime mud residue: 120-160 parts, boron mud: 300-500 parts, aluminum dihydrogen phosphate: 110-150 parts, silicon slag: 1500-1750 parts, expanding agent: 60-80 parts, water reducing agent: 7-10 parts, defoaming agent: 0.2-0.5 parts, modifier: 0.7-1.6 parts, fiber: 3-10 parts, and water: 320-425 parts.

The suspension A prepared in B1 and the silicon slag are put into the double-shaft forced concrete mixer, and mixed and stirred with the slurry A prepared in B2 for 5 minutes to prepare a slurry of a decorative plate blank; B4. The slurry of the blank is poured into a decorative plate forming mold placed on a vibrating table, and the vibrating table is started to vibrate for 60 seconds; B5. The decorative plate forming mold is moved to the glass laminating machine, the surface of the blank paste in the forming mold is covered with a film, and the mold is moved into a curing room with a temperature of 80 DEG C and a relative humidity of 95% for curing for 1 day to complete the preparation of the glazed decorative plate. Before use, the film covering the upper surface of the decorative plate is torn off.

[0009] The cement is one of Portland cement P.O 52.5, Portland cement P.O 52.5R; The silica content of the silica fume is ≥92%, the specific surface area is ≥27 m2 / g, the water requirement ratio is ≤120%, and the activity index is ≥105%; The carbide slag powder is an industrial solid waste generated in the acetylene production process, and the calcium hydroxide content is ≥85%, and the mesh number is 200; The white mud slag is white mud slag powder treated by drying, grinding and screening after being generated in the papermaking of cane pulp, and the calcium carbonate content is ≥83%, the silicon dioxide content is 6-10%, the calcium oxide content is ≥4%, and the mesh number is 250-325; The boron mud is boron mud powder treated by drying, grinding and screening after being generated in the production of boric acid, and the magnesium oxide content is ≥35%, the silicon dioxide content is ≥30%, and the mesh number is 100-200; The aluminum dihydrogen phosphate is a white powder, and the aluminum dihydrogen phosphate content is ≥98%, and the mesh number is 800; The silicon slag is zirconium sand silicon slag, and the silicon dioxide content is ≥65%, the zirconium dioxide content is ≥10%, and the mesh number is 20-100; The expanding agent is GNA high-efficiency anti-cracking waterproof expanding agent; The water reducing agent is early strength type polycarboxylic acid water reducing agent powder, and the water reducing rate is ≥25%, the compressive strength ratio is 1d≥180%, 3d≥180%, 7d≥150%, and 28d≥140%; The defoaming agent is AGITAN P803 defoaming agent; The modifier is tridecafluorooctyltriethoxysilane; The fiber is a mixture of polypropylene fiber and polyvinyl alcohol fiber in a weight ratio of 4:6, wherein the polypropylene fiber has a length of 6 mm, a single filament diameter of 20-25 μm, a tensile strength of 500 MPa, and an elastic modulus of 4-5 GPa; the polyvinyl alcohol fiber has a length of 6 mm, a single filament diameter of 10-20 μm, a tensile strength of 1500 MPa, and an elastic modulus of 30-40 GPa; The film is a PE film with a surface tension of 35 mN / m; The stirring shaft of the electric heating high-speed dispersion tank has a rotating speed of ≥1000 r / min, and the blade linear speed is ≥15 m / s; The forming die is of a size specified in the current national standard JC / T 412.1, JG / T 396.

[0010] The double-shaft forced concrete mixer and the glass laminating machine are conventional equipment in the industry and belong to a known product.

[0011] Due to the above technical scheme, the large-volume multi-solid waste baking-free glazed decorative panel and the preparation method thereof have the following beneficial effects: 1. The present application makes full use of various industrial solid wastes, and the solid waste content is as high as 62%~67%. The industrial solid wastes are consumed, the land resource occupied by the solid wastes is reduced, the environmental problems caused by the large consumption of clay and other non-renewable mineral resources in the prior art, high energy consumption and high carbon emission in the sintering process, etc. are solved, and good social, environmental and economic benefits are achieved.

[0012] 2. The modified agent and the silica ash are fully mixed and contacted by high-speed stirring in an electric heating high-speed dispersion tank. Under the weak acidic environment provided by the 60℃ water temperature and the aluminum dihydrogen phosphate dissolution, the tridecafluorooctyltriethoxysilane is more easily hydrolyzed to generate silanol, which is condensed with the hydroxyl group on the surface of the silica ash to form a stable Si-O-Si covalent bond, and the fluorocarbon is linked to the surface of the silica ash, so that the silica ash is modified to have hydrophobicity and oleophobicity. The hydrophobicity and the ultra-high specific surface area of the silica ash make the modified silica ash more easily float to the surface of the slurry when vibrating, and in the silicate slurry environment, the over-doped modified silica ash reacts with the calcium hydroxide provided by the cement hydration product, calcium carbide slag and white mud slag to generate calcium silicate gel, continuously consumes the calcium hydroxide generated by the cement hydration, and cooperates with the H + ions released by the hydrolysis of the aluminum dihydrogen phosphate and the residual silicic acid in the silica slag to make the pH value of the slurry reach 9~10, so that an environment suitable for the generation of magnesium phosphate crystals is obtained. The aluminum dihydrogen phosphate reacts with the calcium silicate gel and the magnesium oxide in the boron mud under the present mixing ratio, production process temperature and ultra-low water-binder ratio environment, and after hardening, crystalline calcium phosphate, crystalline magnesium phosphate and crystalline magnesium silicate with glass luster are obtained. The upper surface of the slurry can be tightly attached and spread on the PE film with a surface tension of 35 mN / m before hardening, and after hardening, a thin layer of glaze with glass luster, flatness, hardness, hydrophobicity and oleophobicity is obtained, so that the present application does not need various resin-based film-forming aids used in the existing baking-free glaze technology to form a glaze layer or a glue adhesive to paste a glaze layer, avoiding the problems of yellowing, cracking and peeling of the glaze after a certain period of time due to the aging of the resin, and the glaze has the characteristics of hydrophobicity and oleophobicity without additional coating, solving the problem that the existing hydrophobic decorative panel generally sprays a water-repellent agent on the surface, and the coating generally fails within 2~8 years.

[0013] 3. The zircon sand silicon slag is selected in a continuous gradation, the silicon slag is mixed with the slurry in the last stage of stirring to reduce the adsorption of the silicon slag to the water of the slurry, and after the slurry is poured into a forming mold, the coarse granular silicon slag is vibrated to the bottom of the slurry through vibration, and after the slurry is hardened, the coarse granular silicon slag is relatively concentrated at the bottom of the glazed decorative plate. Because the silicon slag contains a large amount of amorphous silicon dioxide, the adsorption is good, so that the bottom surface of the glazed decorative plate has good adsorption. In the field construction, the base surface can be firmly bonded by bonding mortar without pre-soaking. At the same time, due to the ultra-low water-binder ratio of the slurry, the cement stone structure is dense, and during the hydration process, the calcium sulphoaluminate in the expansive agent reacts with the gypsum and calcium hydroxide in the slurry to form ettringite, which is interspersed in the cement slurry to fill capillary pores and micro-cracks. Magnesium oxide is hydrated to form magnesium hydroxide gel, which is interwoven with hydrated calcium silicate gel to further block the water seepage channel, improve the compactness of the matrix, and make the present application have high strength, high frost resistance, water resistance and good bonding construction performance. The problem of low strength and poor frost resistance of the products with good bonding construction performance on the market is solved. The products with high strength need to be soaked for 1 day before being pasted and constructed, otherwise they are easy to be hollowed and fallen off due to poor bonding with the bonding mortar after a period of time.

[0014] 4. The fibers are compounded with polypropylene fibers and polyvinyl alcohol fibers in a certain proportion, and the two kinds of fibers play a synergistic effect to make up for the deficiency of single fiber, so as to improve the impact resistance of the decorative plate. The initial crack resistance is improved by the polyvinyl alcohol fiber with high strength, high modulus and excellent adhesion to the matrix, the micro-crack initiation and expansion is inhibited, and the macro-crack stage of the polypropylene fiber is improved by bridging to increase the energy consumption. Through this "soft and hard combination" synergistic mechanism, the present application has high impact resistance.

[0015] 5. The white mud slag is a white mud waste slag produced by sugarcane pulp papermaking industry of Guangxi papermaking enterprises, and the main component is calcium carbonate. However, because the sugarcane pulp has a relatively high content of silicon dioxide compared with wood pulp, it cannot be recycled and processed to produce calcium carbonate like the white mud of wood pulp papermaking. Therefore, the current treatment method of sugarcane pulp is mainly flue gas desulfurization of thermal power plant or stacking on land. The flue gas desulfurization of thermal power plant can only utilize about 5% of residual alkali in the white mud, and waste slag after desulfurization still needs to be stacked on land, which not only occupies land resources, but also causes environmental pollution. The present application makes full use of the components of calcium carbonate and silicon dioxide in the white mud of sugarcane papermaking by utilizing the component characteristics, and uses them as micro materials and color adjusting agents for decorative panels. The impurities of alkali and silicon in the white mud can also be used for the generation of cement stone, which provides a new way for the treatment of white mud of sugarcane papermaking.
