Description

Black attapulgite plasticine and production method thereof

Technical field

The present invention relates to plasticine, be specifically related to a kind of black attapulgite plasticine and production method thereof.

Background technology

The black plasticine of selling on the market is made up of flour, talcum powder, Paris white, breeze, grease, spices, pigment, sanitas, poster paint, industrial pigment and water.

Flour mixes with water under normal temperature condition, and adhesive property is lower, talcum powder, Paris white and breeze with can not form the mineral colloid after water mixes, be to depend on flour and grease and be bonded together fully.The plastic poor-performing of this plasticine, the finished product after the making are easy to generate drying, cracking, distortion, mouldy and rotten, also can make the operator that a kind of greasy feeling is arranged on hand in making processes, and it is bad to reuse effect.

Use poster paint and the synthetic black plasticine of industrial pigment color to be easy to fade, change beige into, but also can produce pollution.

Summary of the invention

The objective of the invention is to overcome weak point in the prior art, a kind of black attapulgite plasticine and production method thereof are provided.

Black attapulgite plasticine is made up of the sticking attapulgite clay powder of height, propylene glycol, guar gum, dimethyl polysiloxane, pine soot, activity charcoal powder and deionized water.

The production method of black attapulgite plasticine: after propylene glycol, guar gum are dissolved in the deionized water, be gelating soln, the sticking attapulgite clay powder of height, pine soot and activity charcoal powder slowly added in the gelating soln stir, mix the back and be work in-process, dimethyl polysiloxane added in the work in-process stir, the mixture after stirring is the finished product of black attapulgite plasticine.

Attapulgite clay has higher plasticity-under aqueous situation, good stability, and the hardness of attapulgite clay is Mohs 2～3 degree; Attapulgite clay is viscosity when moist, viscosity can reach more than the 3000mPas, the dry post-shrinkage ratio of attapulgite clay is little, and does not produce be full of cracks, and high sticking attapulgite clay powder is the powdery attapulgite stone clay that the complete processing of employing raising viscosity of attapulgite clay is produced.

Propylene glycol is the stable water-absorbent liquid of a kind of water white transparency toughness, and almost tasteless odorless is water-soluble, thereby is widely used as moisture adsorbent, emulsifying agent, antifreezing agent, lubricant and solvent in food, medicine and cosmetic industry.A kind of natural thickening material of guar gum, outward appearance be from white to yellowish free flowing powder, can be dissolved in cold water or hot water, meet behind the water and form gelatinoid, reach the effect of rapid thickening.

Dimethyl polysiloxane is a kind of water white thick liquid, and odorless is tasteless, water insoluble, is used for defoamer, fruit glaze agent and anticaking agent.

Pine soot is to be raw material with the pine tree, and under oxygen situation, oil plant can not fully burn and just form cigarette ash, and collecting its cigarette ash is pine soot, is the black profit of a kind of color and luster, the light and prolonged non-fading natural black pigment of quality.

Gac is that outward appearance that a kind of carbonaceous material is made is that black, the prosperity of internal void structure, specific surface area are big, a class microcrystalline carbon materials of high adsorption capacity.

The present invention is achieved by following technical proposals:

1, the batching of black attapulgite plasticine is made up of following component by weight percentage: high sticking attapulgite clay powder 45～65%, propylene glycol 0.1～10%, guar gum 0.1～10%, dimethyl polysiloxane 0.1～5%, pine soot 0.01～5%, activity charcoal powder 0.01～5% and deionized water 20～35%.

2, the production method of black attapulgite plasticine: (1) adds deionized water in the stirrer earlier, propylene glycol, guar gum is added in the deionized water stir again; (2) after propylene glycol, guar gum are dissolved in the deionized water, be gelating soln, the sticking attapulgite clay powder of height, pine soot and activity charcoal powder slowly added stir in the gelating soln, mix the back and be the work in-process of black attapulgite plasticine; (3) dimethyl polysiloxane is added in the work in-process of black attapulgite plasticine and stir, the mixture after stirring is the finished product of black attapulgite plasticine.

The sticking attapulgite clay powder of described height is the attapulgite clay that adopts the complete processing production that improves viscosity of attapulgite clay, it is characterized in that, and from the attapulgite clay of mining area exploitation, need be through 30～120 days natural weathering; Modification processing method is: calculate by weight percentage, take from the attapulgite clay 94～98% after the right weathering, evenly add 2～6% yellow soda ash, import jointly in the fermentation vat, add clear water and soak ageing, soak time is 72～120 hours; Get the attapulgite clay after the immersion, stir in the input stirrer, and the attapulgite clay after will stirring, be extruded into thin slice through extrusion machine, its gauge control is at 0.5～2 millimeter, with the attapulgite clay thin slice, carry out airing, the attapulgite clay thin slice after the airing, its water content≤15%; Batching is calculated by weight percentage: the attapulgite clay 94～98% after the airing, High hydrophilous resin 0.5～5% and Mierocrystalline cellulose 0.5～3%, above-mentioned batching is stirred, and carry out abrasive dust in the back input grinding machine that stirs, particle fineness≤0.074 millimeter.

Above-mentioned production technique is to adopt " improving the complete processing of viscosity of attapulgite clay " in application on June 20th, 2005 by the inventor, and the Chinese patent Granted publication number is: CN 1317067C, Granted publication day: on May 23rd, 2007.

Black attapulgite plasticine viscosity height, soft plasticity-is good, and the black profit of color and luster is prolonged colour-fast; Have that water-retentivity is strong, shrinking percentage is little, indeformable, not hardening, do not produce be full of cracks, not mouldy, never degenerate not skin irritation, nontoxic, non-corrosiveness and do not have the characteristics of greasy feeling.

The black attapulgite plasticine production technique is simple, and is with low cost, and can be repeatedly used, and the stronger market competitiveness is arranged.

Black attapulgite plasticine is applicable to industrial art shape-designing, art education and toy for children.
