Description
Technical field
The present invention relates to ceramic field, relate in particular to a kind of ceramic size height and admittedly contain promotor and preparation method thereof.
Background technology
Along with ceramic industry constantly uses high-quality china clay, cause the tonerde resource more and more deficienter, because it is non-renewable, ceramic industry is had to bring into use and is contained the more clay of poor material, be used for producing various ceramic products, yet because the congenital defect of material causes the ceramic body undercapacity, slurry is difficult to the problems such as dispergation, causes the product of producing that the defectives such as crackle, the angle of rupture, scarce limit are arranged.At present, what the China ceramic industry head it off generally adopted all is water reducer, and common ceramic water reducing agent is owing to be subjected to the impact of the factors such as molecular structure, relative molecular mass, and its effect is unsatisfactory, especially poor effect on blank strength and viscosity reduction.Affected high flowability and the mold effect that admittedly contains slurry.And the base substrate toughener domestic also mainly be to use methylcellulose gum, treated starch, polyvinyl alcohol etc., these organic high molecular polymer costs higher and also use also convenient not.Therefore, good height contains promotor admittedly can be issued at lower addition excellent effect, keeps good processing performance, promotes ceramic industry to less energy-consumption, high quality, the development of high yield aspect.
Ceramic industry is a high energy consumption industry, and wherein the energy more than 80% all is used to burn till and drying process.Day by day deep along with China's energy-saving and emission-reduction work, ceramic industry is faced with acid test, how energy-saving and emission-reduction become the major issue that current ceramics faces, and a guardian technique problem of energy-saving and emission-reduction is exactly how to reduce to obtain under the add-on of less water, and ceramic size still has preferably blank strength, flowability and lower viscosity.
What research was more at present is the polycarboxylic acid polymeric superplasticizer, and poly carboxylic acid just has high dispersing property and protects preferably the performance of collapsing through suitable modification under low incorporation.General all is to prepare first active large monomer, and then the monomer with certain proportioning mixes direct employing solution polymerization or obtains finished product through steps such as oversulfonate, esterifications.These methods, technique are comparatively complicated, and will introduce organic solvent, the technique such as need to remove after react again, separate complex, and not environmental protection, and market-oriented not, preparation cost is also higher.
And the adding of water reducer can not make blank strength increase, and is also not ideal enough for the ceramic size viscosity reduction dispersion effect that superelevation contains admittedly.
Therefore research admittedly contains ceramic size to height and has base substrate strengthens, viscosity reducing effect is good height and admittedly contain the promotor tool and have very important significance.
