Abstract
The invention discloses a cover glaze which is characterized in that: the constituents of the cover glaze are as follows by weight percentage: 90-96 percent of matte fusion cake, 4-6 percent of gas knife soil, 0.08-0.2 percent of sodium carboxymethylcellulose, 0.03-0.36 percent of industrial sodium tripolyphosphate, and 0.20-0.26 percent of ceramic dispergator, and water accounting for 20-26 percent of total proportion of the raw materials. The preparation process flows of the cover glaze are as follows: raw material incoming inspection--batching--ball milling--detection--deironing and sieving--decaying--warehousing and being sieved by 250 meshes of deironing oscillating screen. The ball milling time is 7-10 hours, and ball-milling glazeslip specific gravity is 1.4-1.9g/cm<3>, and the fineness is 0.6-1.0mm; the flowing speed of the ball-milling glazeslip is controlled above 55s. The cover glaze has the advantages of transparent and smooth performance, bright color and luster and wide market prospect.
Description
Technical field
The present invention relates to the ceramic raw material field, more particularly relate to a kind of prescription and preparation technology thereof of cover-coat enamel.
Background technology
Socioeconomic growth at full speed, driven the development of building trade, and ceramic building materials such as ceramic are higher because of its hardness, wear resistance good, the density height, shrinkage strain is little, good decorating effect, on market, use quite extensive, cover-coat enamel is one deck enamel that covers in enamel or ceramic product manufacturing process on product surface or the ground-coat enamel, plays corrosion-resistantly, and can increase functions such as product decoration effect.At present, cover-coat enamel in the production is of a great variety, as the ceramics of the prior art requirement difference to frit in the glazing program, the performance difference of glaze, glaze volume must have certain thickness, and Properties Control strictness such as temperature in the sintering procedure, product cannot multifuel combustion, and the row of production produces and is restricted, production efficiency is lower, traditional raw glaze is when application product, and poor heat stability easily produces aberration, product is yielding, the scope of application is little, and high-temperature viscosity is big, and promptly temperature flowing is poor, cause glaze to seem coarse, antifouling property is good inadequately, and yield rate is low etc., in addition the product transparency, slicknesss etc. are still waiting the further space of raising.
Summary of the invention
Purpose of the present invention is exactly in order to solve the deficiency of prior art, and a kind of cover-coat enamel that ceramic uses and preparation method thereof that makes that provides, this cover-coat enamel surface transparent is smooth, bright in colour attractive in appearance, and applicable scope is wide, the glaze slip performance is good, firing range is wide, firing property good, and cost is lower; Its preparation technology rationally, simply.
The present invention adopts following technical solution to realize above-mentioned purpose:
A kind of cover-coat enamel is characterized in that, the components by weight of this cover-coat enamel is: mute light frit 90～96%, air knife soil 4～6%, Xylo-Mucine 0.08～0.2%, industrial tripoly phosphate sodium STPP 0.30～0.36%, ceramic dispergator 0.20～0.26%; The water 30～36% that also comprises the above-mentioned raw materials overall proportion.
Preparation technology's flow process of this cover-coat enamel is as follows, the raw material incoming inspection, and------ball milling---detects------old---use of sieving of putting in storage that deironing is sieved to batching.
The ball milling time after the described batching is 7～10 hours, and ball milling glaze slip proportion is at 1.4～1.9g/cm
3, fineness is 0.6～1.0mm; Described ball milling glaze slip flow rate control is more than the 55s; The above-mentioned in addition glaze that the puts in storage 250 purpose deironing vibratory screening apparatuss that to sieve.
The firing temperature of described cover-coat enamel is 1054～1074 ℃.
Described firing period is 50～60min.
The weight of described cover-coat enamel is 50～200g/600*600 dish.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
One, this cover-coat enamel goods good decorating effect, the glaze exquisiteness, clean mark, the transparent light of smooth surface, texture is good, and is applied widely applicable to ceramics and other ceramics, is specially adapted to internal and external wall brick.
Two, hardness height; When cover-coat enamel of the present invention is applied to ceramic, product and traditional ceramics brick glaze face abrasion tester are detected, adopt two kinds of samples to get the 100*100 specification, carry out specimen test simultaneously, setup parameter, commentaries on classics in 4 minutes 1200 is ground, and finds that this product is excellent, and traditional ceramics brick surface is well damage then.
Three, firing temperature is wide; Use firing temperature of the present invention is wide, and glass melting temperature is at 1054～1074 ℃, so burning till difficult aberration, the yield rate height of producing of back finished product.
Four, glaze is smooth, and antifouling property is good; Under equal conditions, adopt product of the present invention and traditional porcelain tile to compare test simultaneously, sample has adopted ink, tea, red wine, olive wet goods to test respectively, after being coated with 30 minutes, cleaning this product can clean up fully, do not leave stain, and the traditional porcelain tile there is obviously stain to exist.
Five, production technique of the present invention is simple, efficient is higher, and production cost is low, because glaze is moist transparent, color development is strong, the difficult generation phenomenon of fading, technical process is succinctly reasonable, has good thermostability, the sintering curve kiln is regulated little, the finished product planeness is good, can not produce the later stage distortion, can reduce cost about 30%.
Six, long service life; Water-intake rate of the present invention is lower than 0.2, and when being applied to suitable environment, moisture-sensitive can not keep the glaze lines clear as new, the texture gracefulness for a long time.
Seven, good product performance; When this cover-coat enamel was applied to ceramic tile, wear resistance was good, the hardness height, and greater than 7, capacity antacid is strong greater than 45Mpa, Mohs' hardness for the product folding strength, and environmental protection is radiationless
Eight, this cover-coat enamel new technology is used the yield rate height, the class height, and the product of producing is the top grade product, compares with traditional raw glaze material, and the production economic benefit has improved more than 25%, has good marketable value.
Embodiment
