Description

A kind of preparation method of the unleaded glaze of domestic ceramics of inexpensive high rigidity
Technical field
The present invention relates to ceramic technology field, more particularly to a kind of system of the unleaded glaze of domestic ceramics of inexpensive high rigidity Preparation Method.
Background technology
Fritted glaze has the advantages that property of glaze is good, safe, stability is good, temperature of glaze firing scope is wide, in daily pottery Porcelain, defend and have very extensive application with fields such as ceramics, architectural pottery, the art pottery, bioceramics.According to performance and application The difference in field, fritted glaze can be divided into leaded fritted glaze, lead-free fritting enamel, clear frit glaze, translucent fritted glaze, milky white molten Block glaze etc..So far, the development of fritted glaze is highly developed, still, as the development and people of society are to product property And the increasingly lifting of security performance requirement so that fritted glaze is reducing cost, safety and environmental protection, properties of product raising and novel product Still there is very big research space in the fields such as research and development.Lead clear frit glaze because melting behaviour is excellent, the transparency is good, glossiness is high, The many merits such as temperature of glaze firing scope is wide, cost is low, and as the representative products in earliest fritted glaze.But lead glaze product exists The phenomenon of lead dissolution inevitably occurs during use, and harm is brought to the health of human body of user, this is also limit The critical defect of lead glaze production development processed.With the development of society, the improvement of people's living standards, people increasingly focus on the person Health and catering product, the security of living environment.Lead glaze product is gradually abandoned by people, and lead-free fritting enamel arises at the historic moment, generation The arena of history is climbed up for lead frit glaze.
Lead-free transparent fritted glaze is substituted with oxides such as Bi2O3, Y2O3, B2O3, MgO, ZnO, BaO, SrO, Li2O Pb O and a kind of fritted glaze prepared, it not only solves the potential safety hazard of lead glaze, and molten with being compared favourably with lead glaze Melting property, the transparency, glossiness, glaze firing performance, are widely used in architectural pottery, domestic ceramics, defend with fields such as ceramics, especially It is the domestic ceramics closely related with food, but this glaze uses the high-alkali composition of high boron more, cost is higher, and product is most In the presence of the transparency it is poor, firing range is narrow, product defects is more the deficiencies of, this just need further to process raw material and technique progress It is modified.
The content of the invention
The object of the invention be exactly in order to make up prior art the defects of, there is provided a kind of domestic ceramics of inexpensive high rigidity without The preparation method of lead glaze material.
The present invention is achieved by the following technical solutions:
A kind of preparation method of the unleaded glaze of domestic ceramics of inexpensive high rigidity, including step in detail below:
(1)Potassium feldspar, quartz sand, calcite, fluorite, glass dust are subjected to ball milling respectively, it is stand-by to cross 120 mesh sieves, then with oxygen Change zinc, borax used 20 mesh sieve to be sufficiently mixed for 2-3 times after mixing;
(2)Corundum crucible is put into melting furnace, starts to add above-mentioned mixed powder after being preheated to 1100-1150 DEG C, using point The mode of secondary dosage is added, and is warming up to 1350-1400 DEG C with 3-5 DEG C/min speed, then temperature control 60-90 minutes, being fused into can Wire drawing state;
(3)The glass metal melted is poured into rapidly into water quenching in cold water, into small frit, to be dried in vacuo after collection, obtain the small of drying Frit, small frit is added in the 1.8-2 times of water measured after stirring and be sent into the progress thick ball milling of one-level, ball in intermittent ball mill Grinding media is zirconium dioxide microballoon, pulp after thick ball milling 40-50 minutes, then is added and continuously run in ball mill by regulating valve, The two level ball milling 30-40 minutes matched by different ball-milling mediums, three-level ball milling 50-60 minutes, last overflow pulp;
(4)By step(3)0.02-0.03% carboxymethyl cellulose is added in obtained glaze slip, is stirred.
A kind of preparation method of the unleaded glaze of domestic ceramics of inexpensive high rigidity, step(1)Described in zinc oxide, boron Sand is chemical pure preparation.
A kind of preparation method of the unleaded glaze of domestic ceramics of inexpensive high rigidity, step(1)Described in potassium feldspar, stone Sand, calcite, fluorite, glass dust, zinc oxide, the proportioning of borax account for respectively total glaze 18.06%, 33%, 15.92%, 7.3%、8.72%、7%、10%。
A kind of preparation method of the unleaded glaze of domestic ceramics of inexpensive high rigidity, step(2)Described in gradation charging Mode specifically refer to:Divide mixed powder to 5-6 batches, control and added within 50-60 minutes.
A kind of preparation method of the unleaded glaze of domestic ceramics of inexpensive high rigidity, step(3)Described in the thick ball of one-level The particle diameter and proportioning of the ball-milling medium of mill are respectively that a diameter of 80mm big ball of zirconium dioxide is accounted in 80%, a diameter of 40mm Ball accounts for 20%;The ball-milling medium proportioning of described two level ball milling accounts for 80% for ball in a diameter of 40mm zirconium dioxide, is a diameter of 20mm bead accounts for 20%;The ball-milling medium proportioning of described three-level ball milling accounts for 20% for ball in a diameter of 40mm zirconium dioxide, A diameter of 20mm bead accounts for 80%.
It is an advantage of the invention that:The present invention by scientific and reasonable composition proportion, do not add Li2O, SrO, BaO, cost of material is reduced, flux and Network former are used as by diboron trioxide, rationally control the addition of borax, energy Enough so that glaze melts fully and has good glossiness and transparency, and frit temperature of glaze firing is low, has energy-saving low-carbon Effect, it is with the obvious advantage compared with the glaze of the high-alkali composition of high boron;Grading ball milling is used during grinding glaze, to replace Intermittent ball mill time processing finished pulp, both ensure that stabilization of the proportioning of glaze before and after ball milling and uniformly, after ball milling Frit particles are finer and smoother uniformly, specific surface area increase, are advantageous to the uniform and stable and steady quality of follow-up glazing, while have again There are higher grinding efficiency and relatively low energy consumption.
Be used for the glazing of household ceramic blank by glaze made of present invention process, by obtained after glaze firing hardness it is high, Glossiness is high, the safe glaze layer of acid and alkali-resistance, and not leaded, harmless, and environmental protection is attractive in appearance, and external quality is excellent while can protect The inherent quality of ceramic body is demonstrate,proved, improves the wear-resisting and mechanical strength of domestic ceramics, whole technical process adheres to low-carbon, section Energy, the environmentally friendly purpose of emission reduction, are worthy of popularization.
