[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The ceramic product of the present invention uses a glaze based on bamboo charcoal modification to glaze the green body, and then sinter and improve to make the ceramic product. The glaze based on bamboo charcoal modification uses quartz, potassium feldspar, calcite and borax as matrix materials, and adds modified bamboo charcoal powder as a blending agent to optimize the functional effect of the product; the modified bamboo charcoal powder is preheated by bamboo charcoal, and then stirred and modified with a modifier solution to optimize the performance effect of the bamboo charcoal powder in the glaze, thereby enhancing the functionality of the product. At the same time, bamboo charcoal itself can optimize the fluidity of the glaze system in the system, so that the glaze is more evenly distributed during the glazing process, ensuring the uniformity of the glaze layer; 2. The modifier solution uses pyrophyllite as the matrix, which is improved by irradiation to activate its activity. At the same time, it is further improved by ultrasonic treatment with silicon carbide fiber solution. The silicon carbide fiber, boron nitride, lanthanum chloride solution and zirconia in the silicon carbide fiber solution are mutually blended and optimized. The needle-shaped silicon carbide fiber is used to reconcile flaky boron nitride, silica and other raw materials to coordinate and optimize pyrophyllite, thereby strengthening and enhancing the system performance, and further improving the performance stability and performance coordination of the system; 3. The glass microsphere carrier is optimized by blending titanium dioxide, cerium oxide and glass microsphere solution. The glass microspheres in the glass microsphere solution are used as the matrix, and the interfacial property and dispersibility between the system raw materials are enhanced by sodium lignosulfonate solution and silane coupling agent KH550. At the same time, titanium dioxide and cerium oxide are further blended, and the glass microsphere carrier thus prepared is better coordinated with the bamboo charcoal modifier, enhancing the coordination of the strength, heat insulation and anti-fouling properties of the system in the system, as well as the waterproof and weather resistance stability of the product; 4. The conditioner based on the modified cordierite body is heat-treated with cordierite at 155 - 165 °C for 10 - 15 min first, then heated to 270 - 280 °C at a rate of 2 - 5 °C / min, held for 20 min, and then air-cooled to room temperature to optimize the activity efficiency of cordierite. Then, it is further processed by ball milling with the modifier. In the modifier, barium carbonate, a 5% sodium dodecylbenzenesulfonate solution by mass fraction, and aluminum borate whiskers are mutually blended and optimized. The whisker-like structure of aluminum borate whiskers coordinates barium carbonate and is incorporated into the cordierite system, thereby further enhancing the performance coordination and stability of the system. Bismuth titanate, nano-molybdenum disilicide, and yttrium oxide are sintered and improved to make the conditioning material, which is further ball-milled twice to cooperate with the modified cordierite body. Thus, the conditioner based on the modified cordierite body strengthens the structure of the green body system and optimizes the system performance in the green body system, thereby further improving the performance effect of the product.

[0078] The products of Examples 1 - 3 and Comparative Examples 1 - 11 are respectively subjected to performance tests of strength, heat insulation and stain resistance under conventional conditions and waterproof and weather-resistant conditions. The waterproof and weather-resistant conditions are to place the products in water for 12 h, and then irradiate them under an ultraviolet intensity of 100 W / m 2 for 12 h. The above is one cycle, and the cycle is repeated 10 times; the test results are shown in Table 1.

[0079] Table 1 Performance test results of the products of Examples 1 - 3 and Comparative Examples 1 - 11:

[0080] It can be concluded from Examples 1-3 and Comparative Examples 1-11 that the highest compressive strength of the product in Example 3 of the present invention can reach 195 MPa, the lowest thermal conductivity can reach 0.02 W / m·k, the antifouling property can reach Grade 5, the compressive strength, heat preservation and heat insulation, and antifouling property of the product can be improved in a coordinated manner, and the waterproof and weather resistance stability effects of the product are remarkable; It can be seen from Comparative Example 1, Comparative Example 7 and Example 3 that when one of the modified bamboo charcoal powder and the modifier based on the modified cordierite body is not added to the product, the product performance deteriorates significantly. Only when the two are used in combination and cooperate synergistically, the product performance effect is the most remarkable; It can be seen from Comparative Examples 1-6 and Example 3 that the bamboo charcoal modifier is not added during the preparation of the modified bamboo charcoal powder, the bamboo charcoal modifier is not treated with the modification liquid, the glass microsphere carrier is not added during the preparation of the modified bamboo charcoal powder, titanium dioxide and cerium oxide are not added during the preparation of the glass microsphere carrier, and the glass microsphere liquid is not added during the preparation of the glass microsphere carrier. The performance of the product shows a deteriorating trend to varying degrees; The modified bamboo charcoal powder prepared by mixing the bamboo charcoal modifier with the specific glass microsphere carrier, titanium dioxide and cerium oxide of the present invention has the most remarkable product performance effect. And when the modification liquid is not used to treat the bamboo charcoal modifier, the product performance also shows an obvious deteriorating trend; It can be seen from Comparative Examples 8-11 and Example 3 that the modified cordierite body is not added during the preparation of the modifier based on the modified cordierite body, the modifier is not added to the modified cordierite body, the blending material is not added during the preparation of the modifier based on the modified cordierite body, and bismuth titanate and nano-molybdenum disilicide are not added to the blending material. The performance of the product also shows a deteriorating trend. The modifier based on the modified cordierite body and the modified cordierite body prepared by combining the blending material and the modifier obtained by the specific method of the present invention have the most remarkable product performance effect. Using other methods instead is not as effective as the present invention.

[0081] Based on the above tests, the modification liquid of the present invention has a great influence on the product performance. Based on this, further exploration of the present invention is carried out.

[0082] Experimental Example 1: Same as Example 3, except that silicon carbide fiber liquid is not added to the modification liquid.

[0083] Experimental Example 2: Same as Example 3, except that boron nitride is not added to the silicon carbide fiber liquid.

[0084] Experimental Example 3: Same as Example 3, except that silicon carbide fiber is not added to the silicon carbide fiber liquid.

[0085] Experimental Example 4: Same as Example 3, except that zirconia was not added to the silicon carbide fiber solution and water was used instead of the lanthanum chloride solution.

[0086] Experimental Example 5: Same as Example 3, except that irradiated pyrophyllite was not added to the modification solution.

[0087] The products of Experimental Examples 1-5 were subjected to the same performance tests, and the test results are shown in Table 2: Table 2 Performance test results of the products of Experimental Examples 1-5:

[0088] It can be seen from Experimental Examples 1-5 that when silicon carbide fiber solution and irradiated pyrophyllite were not added to the modification solution, the product performance deteriorated most significantly among the preparation factors of the modification solution. Secondly, when boron nitride, silicon carbide fiber, or zirconia was not added to the silicon carbide fiber solution, or water was used instead of the lanthanum chloride solution, the product performance showed a deteriorating trend. Only when the modification solution was prepared by the method of the present invention, the product performance effect was the most significant. In the preparation of the modification solution, none of the raw materials can be missing. Only by using the specific raw material ratio of the present invention and using other raw material ratios, the effect is not as significant as that of the present invention.
