Description
Technical field
The present invention relates to a kind of ceramic cold glaze with antibacterial, degerming functions and preparation method thereof, belong to chemical field.
Background technology
" glaze " is to cover that ceramic body is lip-deep is rich in the glassy thin layer of glossiness, and its function is to improve the physics and chemistry performance of billet surface.Conventionally ceramic body surface is loose porous, coarse unglazed, easily stain and attractive in appearance, health and the mechanical property of the disadvantages affect goods such as moisture absorption, and the use of glaze can overcome these shortcomings and improve the performance of goods.First, " glaze " can improve ceramic surface whiteness, glossiness, by increasing color and forming a decoration function such as rich and varied pattern; Secondly, improve goods hardness, increase its thermostability; Then, in chemical property, prevent the erosion of liquid, gas, microorganism, make goods acid and alkali-resistance, anticorrosive and antibacterial.Effect based on glaze on ceramic, glaze is constantly being given prominence to and enhancing in the importance of ceramic industry, directly affects quality and the cost of ceramic.
Traditional enamel frit makeing technology is the performance requriements according to base substrate, and ceramic raw material (quartz, feldspar, clay etc.) and some industrial chemicals are coordinated by a certain percentage, covers billet surface through high-temperature roasting melting, forms the glass coating that is rich in glossiness.Glaze prepared by this technology has strong mechanical property and high glossiness, but because needs burn till (～1350 ℃) under hot conditions, firing period is grown (14-16 hour), and therefore technical qualification harshness, energy consumption remain high, and do not meet the requirement of energy-conserving and environment-protective.At present, some low-temperature sintering technologies start to be applied to the preparation of pottery " glaze ".For example, the firing temperature of crystalline glaze can complete at 1150 ℃-1200 ℃, and in the cycle shorter (50-60 minute), the starting material of employing are take zinc oxide and silicon-dioxide as main, titanium dioxide as nucleator (Liu Yang, etc. Chinese pottery, 2007,43(8), 36-37; Chen Shugang, etc. silicate circular, 2013,32(8), 1661-1665).And if in raw material, add the material such as chromic oxide or plumbous oxide, will be that Tc further reduces, the firing temperature of glaze just can complete (Wang Yongqing, ceramic journal, 2009,30(3) 341-344 at 800～900 ℃ so; Paddy is luxuriant and bdautiful, etc. Chinese pottery, 2010,46(8), 51-53).
But, no matter be traditional high temperature sintering technology or existing crystalline glaze technology, all effectively save energy, reduce burnup, enhance productivity.
Summary of the invention
Technical problem to be solved by this invention is the deficiency existing for above-mentioned prior art and a kind of ceramic cold glaze with antibacterial, degerming functions and preparation method thereof is provided, this pottery cold glaze can be formed at ceramic idiosome surface under the condition that is no more than 100 ℃, and can antibacterial under sun exposure, degerming.
