Background technology
The main raw material of soft ceramic mud is polyvinyl chloride and lime carbonate, binding property is bad under the normal temperature state, prolonged preservation easily wears out and fades, bubble easily during the baking soft ceramic mud,, finished product is burnt and melt if when temperature surpasses 200 ℃, even may cause burning, generate chloride pungency toxic smog, the selling price of soft ceramic mud is higher, is unfavorable for promoting the use of.
The Chinese patent publication number is: CN 101186736, open day: on May 28th, 2008, name is called " a kind of soft ceramic mud and preparation method thereof ", disclose: " a kind of soft ceramic mud and preparation method; it is prepared from by following parts by weight of component: polyvinyl chloride (PVC) paste resin 15~40, bizinc resin 20~55, lime carbonate 15~35, softening agent 0.1~0.4, toner 0.5~0.15, all the other are micro-moisture and impurity ".
The weak point of above-mentioned patent is that the soft ceramic mud main raw material that this technology is produced is polyvinyl chloride (PVC) paste resin, bizinc resin and lime carbonate, and binding property is bad under the normal temperature state, is unfavorable for making moulding, and bizinc resin belongs to dangerous product.
The Chinese patent Granted publication number is: CN 1273531, Granted publication day: on September 6th, 2006, name is called " a kind of manufacture method of transparent texture resin clay ", disclose: " a kind of manufacture method of transparent texture resin clay; it is characterized in that: it is at first mixed together by ethylene powder-vinyl acetate copolymer, starch, glycerol, sanitas, spices and adds water purification again and stir into mud shape thing; and then add whiteruss and mix and stir, vacuum-packed finished product ".
The weak point of above-mentioned patent is that the transparent texture resin clay main raw material that this technology is produced is ethylene powder-vinyl acetate copolymer and starch, ethylene powder-vinyl acetate copolymer has hormesis to eyes and skin, be not suitable for being used to manufacture the raw material of handicraft, need a large amount of starch in this product, be unfavorable for promoting the use of.
Summary of the invention
The objective of the invention is to overcome weak point in the prior art, a kind of production method of blue attapulgite soft ceramic mud is provided.
The production method of blue attapulgite soft ceramic mud is: blue sand shape Attapulgite mixture is added in the horizontal dough mixer that has turned round, and the sodium polyacrylate gelating soln slowly added in the blue sand shape Attapulgite mixture, mix and stir and be blue sand shape Attapulgite mixture; Be sprayed on the blue sand shape Attapulgite mixture with methyl-silicone oil, the work in-process of kneading au bleu Attapulgite soft ceramic mud are pressed into tabular blue attapulgite soft ceramic mud at last, pack to be finished product.
The blue attapulgite soft ceramic mud is made up of Concavo-convex stick after purifying stone clay powder, white bentonite in powder, sepiolite powder, anatase thpe white powder, cobalt blue, pigment dyestuff indigo plant, sodium polyacrylate, propylene glycol, methyl-silicone oil and distilled water.
Use the wet beneficiation craft of Attapulgite, the screening of mineral such as the hydromica in the attapulgite clay, quartz, opal and carbonate is got rid of, obtain a kind of Concavo-convex stick after purifying stone clay, Concavo-convex stick after purifying stone clay soil property exquisiteness, smooth surface, quality is lighter, be viscosity and plasticity-when moist, its viscosity can reach more than the 3000mPas, helps the bonding between the raw material, the dry post-shrinkage ratio of attapulgite clay is little, and does not produce be full of cracks; Described Concavo-convex stick after purifying stone clay powder is that Concavo-convex stick after purifying stone clay is carried out abrasive dust, the Concavo-convex stick after purifying stone clay powder particle fineness that the present invention selects for use≤0.074 millimeter.
The white wilkinite is the wilkinite of a kind of high whiteness and high brightness, have excellent plasticity, cohesiveness and oilness, help improving the intensity after property bright in luster, plasticity-and the seasoning of blue attapulgite soft ceramic mud, the white bentonite in powder particle fineness that the present invention selects for use≤0.074 millimeter.
Sepiolite is a kind of rich fibrous magnesium silicate clay mineral, be light white or canescence, have fine and smooth soft, viscosity is strong, shrinking percentage is low and plasticity-the is good characteristics of satin luster, light weight, help improving property bright in luster, gloss and the mouldability of blue attapulgite soft ceramic mud, sepiolite powder particle fineness≤0.074 that the present invention selects for use millimeter.
Anatase thpe white powder has excellent water dispersible and remarkable optical property, form and aspect stability, size-grade distribution is good, characteristics with high gloss, high reducing power, high covering power, anatase thpe white powder particle fineness≤0.005 that the present invention selects for use millimeter helps improving the property bright in luster of blue attapulgite soft ceramic mud.
Cobalt blue is a kind of blue powder, has fabulous opacifying power, the color transparency and high-strength characteristics, cobalt blue particle fineness≤0.045 that the present invention selects for use millimeter.
Pigment dyestuff indigo plant is a kind of blue powder, has lovely luster, strong coloring force, sun-proof excellent property, acidproof, alkaline-resisting and do not have characteristics of transport property, the blue particle fineness of the pigment dyestuff that the present invention selects for use≤0.045 millimeter.
The present invention selects cobalt blue and pigment dyestuff indigo plant simultaneously for use, can make full use of the advantage of two kinds of blue pigmentss, helps making the color of blue attapulgite soft ceramic mud more bright-coloured.
Sodium polyacrylate is a kind of white powder, odorless, tasteless and nontoxic can be slowly soluble in water, forms utmost point heavy-gravity transparent gel, have thickening, emulsification, figuration, multiple function such as expanded, stable, can improve the cohesiveness and the ductility of blue attapulgite soft ceramic mud.
Propylene glycol is the stable water-absorbent liquid of a kind of water white transparency toughness, and is water-soluble, in the present invention as solvent, emulsifying agent, frostproofer and lubricant.
Methyl-silicone oil is a kind of water white thick liquid, has colourless, tasteless, not volatile and water-fast characteristics, in the present invention as defoamer, releasing agent, lubricant and optical brightener.
Distilled water is meant with the pure water of distillating method preparation, uses distilled water can effectively improve the viscosity of sodium polyacrylate gelinite in the present invention.
The present invention is achieved by following technical proposals:
1, the production method of blue attapulgite soft ceramic mud is: 1. blue sand shape Attapulgite mixture is added in the horizontal dough mixer that has turned round, and the sodium polyacrylate gelating soln slowly added in the blue sand shape Attapulgite mixture, mix and stir and be blue sand shape Attapulgite mixture; 2. blue sand shape Attapulgite mixture is added in the kneader, be sprayed on the blue sand shape Attapulgite mixture work in-process of kneading au bleu Attapulgite soft ceramic mud with methyl-silicone oil; 3. blue attapulgite soft ceramic mud work in-process are added in the oodle maker and press repeatedly 2~4 times, be pressed into tabular blue attapulgite soft ceramic mud at last, pack and be finished product.
2, the batching of blue attapulgite soft ceramic mud is made up of following component by weight percentage: blue sand shape Attapulgite mixture 60~85%, sodium polyacrylate gelating soln 10~35% and methyl-silicone oil 0.1~5%.
