Preparation method for novel porcelain tire body inorganic repairing material and porcelain product repaired by inorganic repairing material

Abstract

The invention discloses a preparation method for a novel porcelain tire body inorganic repairing material and a porcelain product repaired by the inorganic repairing material. Kaolin and commercially pure chemical raw materials are adopted. The novel porcelain tire body inorganic repairing material is prepared from the following raw materials in percentage by weight: 55 to 62 percent of kaolin, 10 to 15 percent of sodium hydroxide, 6 to 9 parts of sodium silicate, 8 to 10 percent of beta-semi-hydrated gypsum and 10 to 17 percent of deionized water. The inorganic repairing material is obtained by calcining, ball milling, drying and stirring the raw materials. By adopting the preparation method, the defects of sparse structure, low strength, high water absorption and lack in porcelain quality due to repair of a porcelain tire body with gypsum are overcome; moreover, the novel inorganic repairing material is scientific and reasonable in production method, is easy to implement, and has a wide market prospect.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials (ceramics), and in particular relates to a preparation method of a novel inorganic restoration material for porcelain carcass and a restored porcelain product. Background technique [0002] Repairing porcelain carcass is also called carcass filling. There are roughly three methods: one is gypsum filling, which is simple, convenient and low-cost. It is the main method of porcelain repairing and filling at present. The texture of porcelain, and it is easy to absorb moisture and expand, which will cause new damage to the utensils; the second is to fill the gap with porcelain powder or stone powder and adhesive, use old porcelain, crush and sieve, add epoxy resin and other adhesives, and shape and cast Filling in gaps, but it is easy to age and change color; the third is to fill gaps with porcelain and porcelain, that is, to fire another ceramic piece that is the same as the original ob...

[0002] Repairing porcelain carcass is also called carcass filling. There are roughly three methods: one is gypsum filling, which is simple, convenient and low-cost. It is the main method of porcelain repairing and filling at present. The texture of porcelain, and it is easy to absorb moisture and expand, which will cause new damage to the utensils; the second is to fill the gap with porcelain powder or stone powder and adhesive, use old porcelain, crush and sieve, add epoxy resin and other adhesives, and shape and cast Filling in the vacancy, but it is easy to age and change color; the third is to fill the vacancy with porcelain and porcelain, that is, to burn another ceramic piece that is the same as the original object, and to fill the vacancy after cutting and grinding, which is extremely difficult and difficult to popularize.

It can be seen that the current restoration of porcelain, especially the restoration of ancient famous porcelain, has certain technical defects, and it is difficult to meet the relevant needs.

[0003] At present, there is no report of using other inorganic cementitious materials to repair porcelain carcass. Therefore, ceramic mineral raw materials are used to prepare an inorganic cementitious material that solidifies rapidly at room temperature and has similar physical properties to porcelain carcass. It is used to repair porcelain carcasses. Body, especially the ancient famous porcelain body has great innovation and application prospects
