Abstract

The invention discloses an antibacterial insulating glass plate and a preparation method thereof and belongs to the field of tableware. The antibacterial insulating glass plate is prepared from, by weight, 25-45 parts of modified diatomite, 20-40 parts of silicon dioxide, 15-35 parts of composite fiber, 10-30 parts of nano silicon carbide, 5-15 parts of boron nitride, 5-25 parts of sodium silicate, 15-35 parts of borax pentahydrate, 15-35 parts of calcium carbonate, 5-25 parts of graphene nanoplatelets, 4-12 parts of xylogen and 10-30 parts of sintering aids. The preparation method includes that part of the raw materials of silicon dioxide and the like are subjected to ultrasonic dispersion prior to being placed in a ball mill, the sintering aids and xylogen are added for ball mill drying, and the rest raw materials are then added for treatment of melting, casting molding, annealing, tempering and the like to obtain the glass plate. The glass plate is high in strength, good in insulation, antibacterial, bright in color, exquisite in quality, suitable for microwave heating, high in adaptability and long in service life.

Description

technical field [0001] The invention belongs to the field of tableware manufacturing, and in particular relates to an antibacterial heat-insulating glass dinner plate and a preparation method thereof. Background technique [0002] Dinner plates are daily necessities that people use a lot, and the hygiene of dinner plates is also closely related to people's health. At present, high-temperature disinfection is required for daily use of dinner plates (especially public places such as restaurants and hotels), but Disinfected dinner plates will come into contact with various secondary pollution sources during transportation, storage, and use, and secondary pollution is inevitable, so the hygiene of the dinner plate is very worrying, especially the primary dinner plate. , its pollution problem is particularly prominent, how to enhance the antibacterial properties of dinner plates has become a research direction in the industry. [0003] Traditional dinner plates are mainly made o...
