Description
Technical field
The invention belongs to ceramic technology fields, and in particular to a kind of preparation method and application of antibacterial surface ceramics.
Background technique
Ceramics, be traditionally using natural clay and various natural minerals as primary raw material, by ingredient, molding and drying,
The general designation of various implements made from the techniques such as calcining, belongs to silicate industry scope.It is also the general name of pottery, stoneware and porcelain,
And it makes pottery and is the difference of raw material soil and processing temperature with the fundamental difference of porcelain.With the development of modern science technology, in the last hundred years
Occurring many new ceramic kinds again, some do not use or are rarely employed the traditional ceramics raw material such as clay, feldspar, quartz,
It even is expanded to non-silicate, the range of non-oxidized substance, and many new techniques occurs.In some documents of American-European countries
" Ceramic " is interpreted as to the common name of various inorganic non-metal solid materials.
Ceramic material and product have many advantages, such as hardness height, good stability of the dimension, wear-resisting, resistance to oxidation, high temperature resistant, answer extensively
For industries such as health, medical treatment, life household, civilian and industrial buildings.With social development and improvement of living standard, people
Requirement to quality of life and living environment is also higher and higher, and SARS epidemic in 2002 and the bird flu wreaked havoc in recent years make one
Recognize the importance of living environment health.Anti-bacteria ceramic is a kind of environment-friendly novel functional material, is antibacterial material, anti-
Product of the bacterium technology in conjunction with ceramic material.It keep ceramic inherently using the same of function and decorative effect
When, it is able to suppress or is killed the harmful microorganism for being attached to its surface, has the function of antibacterial, deodorization, self-cleaning etc., by consumer
Welcome, have a vast market prospect, and the research and development of anti-bacteria ceramic technology also become the hot spot in antibacterial field.
Early in late 1980s, developed country just takes the lead in hospital, dining room, senior house using antibacterial building hygiene
Ceramic.Japan is the pioneer of development and application anti-bacteria ceramic.1999, Japan maximum potting company INAX developed one
The Kilamic anti-bacteria ceramic of kind argentiferous, can preferably inhibit the growth of product surface bacterium.Japanese TOTO and Sai Na company
Realize nano-antibacterial keep a public place clean ceramics batch production.Currently, Japanese anti-bacteria ceramic and ceramic tile have anti-microbial property mostly, it is real
It is now commercialized, is widely used in the places such as hospital, school and food processing, and be on sale all over the world.The U.S., Germany, South Korea also phase
After construction sanitary ceramic, in terms of introduce anti-biotic material.As Sai La Mintek of South Korea and Qing Nan university close
Make obtained antibiotic ceramic tile and launches domestic and international market in batches.The U.S. just puts into 2.4 hundred million dollars of expansion early in the 1980s and resists
The research of bacterium ceramics.
The research of China's anti-biotic material since the 1990s, by nearly development in 20 years, achieve it is a series of at
Fruit, but compared with developed countries, there are still larger gaps in terms of anti-bacteria ceramic industrialization in China.
Production of Ceramics process is complicated, including the processes such as sorting, the preparation of base glaze, molding, green compact drying, glazing, firing.Pottery
Porcelain manufacturer usually after determining raw material and technique, seldom change firing process, mostly use adjustment batching of body and glaze form into
The research and development of row product are modified, therefore antibacterial glaze is the key that prepare anti-bacteria ceramic.The processing characteristics of china industry mention antibacterial agent
Gone out higher performance requirement, be embodied in: strong antibacterial, antibacterial long-term effectiveness have very strong heat-resisting ability,
Safety adapts to ceramic preparation process, on ceramic appearance, quality, mechanical and physical performance without influence etc..Currently, common antibacterial
Agent is divided into organic antibacterial agent and inorganic antiseptic two major classes, and inorganic antiseptic has high temperature resistant, safety, broad-spectrum antiseptic, lasting etc.
Advantage, therefore become the first choice of anti-bacteria ceramic antibacterial agent.Currently, both at home and abroad for the inorganic antiseptic in antibacterial ceramic products
Mainly there are three classes: metal ion mixing type, photocatalyst-type and activated by rare earth elements silver system, photocatalysis series antibacterial agent.
There are two main classes for the technology of preparing of anti-bacteria ceramic: one kind is to add the metal ion of antibacterial agent (mainly in glaze
Ag+) stripping property anti-bacteria ceramic, conventional method is that the antibacterial agent of the metal ions such as argentiferous is added directly into ceramic glaze, work
Skill is simple, operates conveniently, and is suitble to large-scale production, using more in large-scale production.This method requires antibacterial glaze and base
Body and former glaze matched guarantee that the original performance of product cannot be influenced while antibacterial effect；Another kind of applied in glaze layer surface
The photocatalyst-type anti-biotic ceramics of catalysis material are applied, which is in the ceramic product surface titanium dioxide coating prepared or two
The film of titania addition metal ion realizes antibacterial functions using low-temperature sintering.Chinese patent CN106082959A passes through
Metal salt is dispersed in tetra-n-butyl titanate by sol-gal process, then anti-bacterial powder is made by calcining, then with ceramic batch
Anti-bacteria ceramic is made in high-temperature calcination together, and the method preparation process is complicated, needs high-temperature calcination, and energy consumption is high.Chinese patent
It is thin that CN1579999 using sol-gal process and the preparation of chemical vapour deposition technique combination technique in ceramic surface prepares anti-bacteria ceramic
Film, but vapour deposition process antibacterial effect needs to be further increased.
In summary mainly have the problem of anti-bacteria ceramic technology of preparing with difficult point: (1) chemically due to silver ion
Matter is active, and silver-series antibacterial agent is coated on ceramic surface or is added in ceramic glaze, can cause ceramic discoloration, and what glossiness was deteriorated asks
Topic, and generally existing additive amount is big when in use for silver-series antibacterial agent, higher cost, while may also bring safety issue；
(2) surface applies in technique, and antibacterial material is coated in ceramic surface, since firing temperature is lower, antibacterial material and ceramic surface
It in conjunction with insecure, is worn vulnerable to scraping, it is poor to show as durability, and film generates complex process, be difficult to control, Ke Nengying
Products appearance is rung, while in sintering process, organic solvent volatilization that may be present, influences environment in film；(3) photocatalysis is anti-
Microbial inoculum has both the features such as antibacterial, degradation, purification, good durability, but competence exertion must act under ultraviolet light, but also exist
Quantum yield is low, the poor defect of heat resistance.Light absorption and the low and poor heat resistance of photocatalysis efficiency, cause nano-titanium system
There are serious use and technological problems for anti-bacteria ceramic, and this greatly limits its use scopes.
Summary of the invention
To solve ceramic surface antibacterial agent durability of the existing technology and poor adhesive force and defect at high cost, this
Invention provides a kind of preparation method of antibacterial surface ceramics.
The present invention containing antibacterial metal silver, copper, zinc dispersion solution in, titanium salt is added, it is anti-by control hydrolysis
