Description
Technical field
The present invention relates to ceramic green body reinforcing agent, and in particular to a kind of high-efficiency ceramic base substrate enhancer compositions and its be made
Product, belong to ceramic additive and Production of Ceramics field.
Technical background
Ceramic industry is high pollution, high-energy source consumption, high resource consumption " three high industries ", quick with ceramic industry
Development, tonerde resource is more and more deficienter, energy-saving and emission-reduction, appropriateness be thinned be Chinaware Progression the only way which must be passed.The preparation of blank
Link is very important, and the dry tenacity of base substrate is then an important indicator, its yield rate and quality to product has weight
Influence.In current Production of Ceramics, the low phenomenon generally existing of yield rate caused by green strength deficiency, suitably thinned pottery
Porcelain products, its green strength and are remarkably decreased into porcelain intensity, and during conveying and use, the probability of damage or cracking is significantly
Increase.And present ceramic product specification has the trend for the more doing the more big, thus improve blank strength for Production of Ceramics particularly
It is important.It is a kind of important means for improving blank strength to select efficient base substrate reinforcing agent.
Base substrate reinforcing agent has two class of organic reinforcing agent and inorganic strengthening agent.Inorganic strengthening agent usually has bentonite, waterglass
Deng, organic reinforcing agent through it is common have methylcellulose, carboxymethyl cellulose, hydroxyl methylcellulose, polyvinyl alcohol, POLYPROPYLENE GLYCOL with
And alginate etc., there is new ceramics reinforcing agent such as Sodium Polyacrylate complexing agent, modified starch polymer etc. again recently.City
Commodity base substrate reinforcing agent has two kinds of powder and liquid on face, the former readily packaged transport but easily moisture absorption conglomeration, the latter are then easy to
Disperse in ceramic slurry, use is more convenient.
For example, Li Jiake etc. has synthesized a series of Sodium Polyacrylate of different relative molecular masses, applied to artistic porcelain
In base substrate, have studied influence of the Sodium Polyacrylate to the body of artistic ceramics intensity, deformation rate, and Sodium Polyacrylate is strengthened mechanism into
Discussion is gone；The result shows that Sodium Polyacrylate can effectively improve the fabrication strength of the body of artistic ceramics, reduce the deformation of base substrate
Rate, when the mass fraction that reinforcing agent c is added is 0.6%, the dry tenacity increment rate of base substrate is up to 167.5%, the deformation of base substrate
Rate is reduced to 10% from 50%.But Sodium Polyacrylate reinforcing agent there are it is expensive, still to coordinate inorganic strengthening agent to make
The characteristics of using.
