Abstract
The invention discloses an additive suitable for magnesium household porcelain and an application method of the additive. The application method comprises the steps of: compounding and optimizing 0.5-1 percent of a dispersant, 19-27 percent of a flexibilizer, 2-5 percent of a coupling agent, 50-65 percent of methylcellulose, 5-13 percent of polyethylene glycol, 3-7 percent of maleic anhydride-sodium acrylate and 2-5 percent of melamine, and then adding 0.5-2 percent of the additive into a slurry formula of the magnesium household porcelain to prepare thinner and more transparent magnesium household porcelain with a higher breaking strength. Moreover, the application method meets the requirements of low cost and high grade of export production, therefore, the household porcelain additive has a wide application prospect.
Description
Technical field
The invention belongs to domestic ceramics field of material technology, be specifically related to a kind of additive and the using method thereof that are applicable to magnesia household china.
Background technology
Magnesia porcelain is the main product of high-grade household ceramics export foreign trade, and porcelain body is as white as polished jade, sparkling and crystal-clear pool profit.It both had traditional high-grade porcelain free of pinholes, without fall slag, immaculate, colourless dirty, without scratch, glaze paint light, footing light, opening's edge light, be out of shape little requirement, there are again the advantages such as physical strength is high, thermal stability good, lead-indium alloy is low, acid and alkali-resistance, and are suitable for the modern ways of life such as machine washing, high temperature steaming sterilization, electric oven continuous high temperature and microwave heating.But due to raw materials for production, cause current magnesia daily ceramic product thickness thicker, seriously hinder the lifting of the class of its product.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of technique is simple, synthesis cost is low, the additive being applicable to magnesia household china of stable performance and using method thereof.
For solving above technical problem, technical scheme of the present invention is: a kind of additive being applicable to magnesia household china, it is characterized in that including following component by weight percentage:

Trimeric cyanamide 2 ~ 5%
Wherein:
Described dispersion agent is water glass, sodium carbonate, trisodium phosphate, Sodium hexametaphosphate 99, tripoly phosphate sodium STPP wherein one or more;
Described toughner is liquid silastic, polyethers, polysulfones, polyimide wherein one or several.
Described coupling agent is the KH-550 that union carbide corporation of the U.S. produces.
The molecular mass of described polyoxyethylene glycol is 5000-7000.
The molecular weight of described maleic acid anhydride-propenoic acid sodium is 8000-10000.
The using method of above-mentioned additive, is characterized in that comprising the steps:
The first step: dispersion agent, toughner, coupling agent, methylcellulose gum, polyoxyethylene glycol, maleic acid anhydride-propenoic acid sodium, trimeric cyanamide are carried out being mixed and made into additive according to proportioning;
Second step: by magnesia household china formulated blank;
3rd step: by weight percentage the additive of 0.5 ~ 2% is added in magnesia household china blank, and by ball milling household china blank mixed with additive and namely complete modification.
Described magnesia household china formula is attaclay 14 %, burns attaclay 36%, talcum 40%, Jiepai clay 4 %, outstanding col soil 4%, Pingjiang River feldspar 2%.
Innovation of the present invention there are provided a kind of additive that can reduce magnesia household china thickness, be applicable to most of magnesia household china blank raw material, and meet the low cost of outlet production, high-grade needs, be ideal domestic ceramics additive, therefore there are wide market outlook.
