Abstract
The invention relates to a method for producing mellow concave-convex rod suspension. Wherein, it comprises mixing convex-concave rod clay, magnesia, sodium silicate, and macrogol, emerging in emerge pool, compressing in rolling machine, drying, grinding in grinder, and packing. The invention has low cost without using water in preparing casting coat, with suspension rate, non deposit, and high anti-adhesive property.
Description
Technical field:
The present invention relates to suspending agent, be specifically related to a kind of production method of water-based concave-convex stick suspending agent.
Background technology:
Water base suspending agent has production efficiency height, characteristics such as cheap and applied widely, in China's Foundry Production, obtained extensive use, but, the problem that water base suspending agent exists is more, mainly show as the cast paint that uses water base suspending agent to make, easily producing precipitation in long-term storage and transportation, secondly is that the coating brush mark is serious, influences the surface quality of foundry goods.
Good dispersed suspending agent can not only guarantee the dispersing uniformity of each component of coating and the suspension effect of coating effectively, and can also improve the brushability of coating, helps applying, and improves the surface quality of coating and foundry goods.The primary raw material of present water base suspending agent is to select bentonite for use, because bentonite suction back expansion multiple is bigger, directly has influence on the dispersion suspension and the stability of suspending agent, and coating loses adsorbed water when oven dry, be easy to generate crackle.
Chinese patent Granted publication CN1038817, Granted publication day is on June 24th, 1998, name is called: " a kind of composite dispersed suspending agent that is used for cast paint ", disclose: " a kind of composite dispersed suspending agent that is used for cast paint; when the coating that is used for water or organic solvent, it is respectively by 75～85% rectorites; 3～5% tertiary sodium phosphates; 8～12% sodium phosphate trimers; 4～10% sodium carboxymethylcelluloses or 65～78% rectorites; 10～18% tertiary sodium phosphates, 2～5% sodium phosphate trimers, 2～8% polyvinyl butyral resins, 2～5% polyethylene glycol, 1～4% calcium stearate is formed.It is good to adopt the present invention to make the suspension and the crack resistance of the coating that dispersed suspending agent produces, the refractoriness height, thixotropy and brushability are good, long-time place be difficult for precipitate, do not lump, do not harden, easily stirring, redispersibility is good, and low cost of manufacture ".
Use the primary raw material of rectorite in the foregoing invention, recognize that according to retrieval its effect is relatively good, but production cost is still higher, be unfavorable for popularizing in an all-round way use as suspending agent.
Summary of the invention:
The objective of the invention is to overcome weak point in the prior art, provide that a kind of production technology is simple, cheap, suspensibility, plasticity, caking property and lubricity production method of reasonable water-based concave-convex stick suspending agent all.
Water-based concave-convex stick suspending agent is made up of Concave-convex clay rod, bentonite, magnesia, sodium metasilicate and sodium carboxymethylcellulose.
Concave-convex clay rod has unique rod-like fibre crystal shape structure, formed space structure is difficult for being opened, viscosity can be up to more than the 3000mpa.s, dry post-shrinkage ratio is less, dryout or sintering after do not crack, be better than other clay with its excellent caking property, suspension and thickening property, the refractoriness of Concave-convex clay rod is a bit weaker.
The bentonite absorption speed is slow, but water absorption rate and expansion multiple are big, can adsorb 8～15 times of water yields to this volume, dryout or sintering after easily crack, refractoriness is better.
Magnesia can improve Concave-convex clay rod and bentonitic dispersion viscosity, suspendability and refractoriness.
The sodium metasilicate cementitiousness derives from the silicon gel, so be widely used as binding agent, plays the thixotropic effect of enhancing in the batching of water-based concave-convex stick suspending agent.
One of key property of sodium carboxymethylcellulose is the full-bodied colloidal solution of formation soluble in water, and thickening property, flowability and dispersed are preferably arranged.Add sodium carboxymethylcellulose Concave-convex clay rod and bentonite are carried out modification, make both performances obtain complementation, have suspensibility, plasticity, caking property, lubricity, refractoriness and heat endurance preferably in water base suspending agent, hot green tensile strength and dry-pressing intensity all are greatly improved.
The present invention is achieved by following technical proposals:
1, the production method of water-based concave-convex stick suspending agent:
Concave-convex clay rod, bentonite, magnesia, sodium metasilicate and sodium carboxymethylcellulose are mixed by the batching requirement, add water in the input fermentation vat after mixing and soak, soak time was controlled at 24～72 hours; Mixture input twin rollers after the immersion pushes and is tablet, and the THICKNESS CONTROL of tablet is at 0.5～2.0 millimeter; Tablet is transported to the cement threshing ground and carries out airing, the water content of tablet≤13% after the airing, and the input grinding machine carries out abrasive dust, and grain fineness≤0.044 millimeter is packaged as finished product.
2, the batching of water-based concave-convex stick suspending agent comprises following component by weight percentage: Concave-convex clay rod 65～85%, bentonite 5～25%, magnesia 1～5%, sodium metasilicate 1～8% and sodium carboxymethylcellulose 0.05～5%.
The water-based concave-convex stick suspending agent production technology is simple, and cost is very cheap, be used to make water base cast paint after, have that suspensibility height, thixotropy are stable, the brushing performance is good, do not precipitate, do not lump and the characteristics of good fluidity.The suspensibility of water-based concave-convex stick suspending agent: 8 hours=100%, 24 hour 〉=99.5%, 72 hour 〉=99%, 15 day 〉=98.0%.
Water-based concave-convex stick suspending agent is applicable to makes water base cast paint.
The specific embodiment:
Below in conjunction with embodiment, the invention will be further described:
1, the production method of water-based concave-convex stick suspending agent is:
Concave-convex clay rod, bentonite, magnesia, sodium metasilicate and sodium carboxymethylcellulose are mixed by the batching requirement, add water in the input fermentation vat after mixing and soak, soak time was controlled at 48 hours; Mixture input twin rollers after the immersion pushes and is tablet, and the THICKNESS CONTROL of tablet is at 0.5～1.5 millimeter; Tablet is transported to the cement threshing ground and carries out airing, the water content of tablet≤13% after the airing, and the input grinding machine carries out abrasive dust, and grain fineness≤0.044 millimeter is packaged as finished product.
2, the batching of water-based concave-convex stick suspending agent comprises following component by weight percentage: Concave-convex clay rod 80%, bentonite 10%, magnesia 3%, sodium metasilicate 5% and sodium carboxymethylcellulose 2%.
