Embodiment Construction

[0023] In terms of parts by weight, put 20-25 parts of calcium borate, 30-35 parts of blast furnace slag, and 10-15 parts of fly ash into a small mixer and mix the materials for 5-8 minutes to obtain a mixed powder, which is fed to the mixed powder Add 8 to 10 parts of silica sol with a mass fraction of 40%, and 80 to 100 parts of deionized water, and mix evenly to obtain a mixed slurry; add a sodium hydroxide solution with a mass fraction of 40% to the mixed slurry, and adjust the pH to 10.0~10.5, let it stand for 2~3 hours, put the above mixed slurry in the planetary ball mill, control the weight ratio of the ball to material to 10:1, the ball milling speed is 400~500r / min, ball mill 1~2h, continue to the planetary ball mill Add 2% n-butanol of the weight of the mixed slurry and let it stand for defoaming for 40-50 minutes to obtain a soft porcelain slurry; put 400-500g of degummed bone into a calciner, heat up to 200-300°C, and heat-preserve and calcinate for 40-50 minutes...

Abstract

The invention discloses a preparation method of microbubble energy-saving soft porcelain, belonging to the technical field of building and decoration material preparation. The energy-saving effect ofthe soft porcelain is embodied in two aspects. The soft porcelain is mainly prepared from blast furnace slag and fly ash, that is, the soft porcelain meets environment protection and energy conservation requirements in material utilization. During press forming process, silica sol infiltrates into liquid paraffin to form a silica core structure, wherein the liquid paraffin is used as a phase-change temperature-regulating material. In the invention, a liquid phase during sintering mainly comes from the silica sol, and amorphous silica in the silica sol is first subjected to gel dehydration andparticle aggregation during heating process, nitrogen in ammonia gas is fixed into fermentation filter residue through the slight rotting effect of microorganisms in peels, the nitrogen-containing fermentation filter residue and soft porcelain slurry are mixed and then subjected to hot press sintering to form a hexagonal boron nitride crystal, thereby improving the heat preservation and energy conservation effect; bone powder added contains hydroxyapatite crystals and amorphous hydrogen phosphate, so that the soft porcelain looks more textured, and has broad application prospects in building decoration materials.

Description

technical field [0001] The invention discloses a preparation method of microbubble energy-saving soft porcelain, which belongs to the technical field of preparation of construction and decoration materials. Background technique [0002] Soft porcelain, also known as "soft porcelain". What distinguishes soft porcelain from traditional ceramics is its texture. Soft tiles are soft in texture, feel like cowhide, with prominent patterns and strong three-dimensional effect. Because the carcass contains more glass phases, the firing temperature is lower and the transparency is better, but the hardness and strength are poor, and the product is easily deformed. . This kind of porcelain originated in Florence, Italy in 1568. Part of the white porcelain produced in the northern region of my country, as well as the frit porcelain and bone ash porcelain used for decoration and furnishing, all belong to this category. [0003] Main raw materials of soft ceramic technology products: or...
