Abstract
A process for preparing non-dusting hydros by hydroxy-contained alcohol polymer includes such steps as proportioning the hydroxy-contained alcohol polymer as assistant and the hydros in Wt. ratio of (0.2-1):100, using methanol as solvent to preparing the assistant solution at 60-70 deg.C while stirring, adding the solution to the washed hydros, immersing for 1-10 min, and filtering with high-pure nitrogen gas under at least 0.2 MPa.
Description
Technical field: the present invention relates to a kind of production method of not having the dust vat powder and products thereof, particularly do not have method of dust vat powder and products thereof as wrapping up auxiliary agent production with the alkoxide polymer that contains hydroxyl.
Background technology: the method for the synthetic vat powder of existing industrial sodium formate method is: the material after synthetic, filter, washing, dry, cooling, piece together and mix the back and obtain the manufactuerer's output insurance powder through four unification moisture eliminators, this product objectively exists poor stability, smell big, uses to consume shortcomings such as high, that dust is big.
Summary of the invention: purpose of the present invention is exactly to solve that the product stability that background technology exists is poor, smell big, use and consume shortcomings such as high, that dust is big.Solving this technical problem the technical scheme that is adopted is: the alkoxide polymer production that a kind of usefulness contains hydroxyl does not have method of dust vat powder and products thereof, material after synthesizing in the synthetic vat powder method of sodium formate method, filter through four unification moisture eliminators, washing, dry, cooling, piece together mixed back and obtain not having the dust vat powder, it is characterized in that washing the compounding agent solution that the back adds the alkoxide polymer that contains hydroxyl, (1) preparation of this compounding agent solution is: with contain hydroxyl and molecular weight make auxiliary agent greater than 5000 alkoxide polymers, by auxiliary agent and vat powder weight ratio is 0.2～1.0: 100 take by weighing auxiliary agent, in auxiliary agent preparation pot, make solvent with methyl alcohol, be mixed with 2～15% compounding agent solution, the control solvent temperature is 60～70 ℃, stirs auxiliary agent is dissolved fully; (2) interpolation of compounding agent solution is: the compounding agent solution for preparing is joined in the vat powder that washing is good in four unification moisture eliminators, leave standstill to soak and auxiliary agent is fully contacted behind the 1-10min with material and reach abundant bonding parcel, use then that 0.2Mpa is above, the nitrogen of content 〉=99.5% is above-mentioned compounding agent solution press filtration, carry out drying, cooling, assembly by drying program again and make no dust vat powder product after mixing.Wherein, with molecular weight greater than 5000 polyoxyethylene glycol as auxiliary agent, also the useful molecules amount greater than 5000 polyvinyl alcohol as auxiliary agent; Preferable range by auxiliary agent and vat powder weight ratio is 0.3～0.8: 100 take by weighing auxiliary agent; Be mixed with the compounding agent solution of 2.5～9.5% preferable range; Methanol solvate adds preceding with the gas in the nitrogen replacement preparation pot in auxiliary agent preparation pot.
The beneficial effect that the present invention and background technology comparison are had is: owing to adopt technique scheme, one, since present method adopt contain hydroxyl and molecular weight greater than 5000 alkoxide polymer as auxiliary agent, this auxiliary agent has the following advantages: (1) has film forming ability to can be used for parcel; (2) have sufficient chemical stability, do not have the side effect that influences user's derived product result of use; (3) water-soluble and pure, both be fit to the existing working condition of vat powder, also be fit to client's working conditions; (4) have thermostability, do not decompose, never degenerate, antioxidant capacity is strong, is fit to preservation condition and application conditions; (5) have certain adhesive capacity, can make small dust bonding.Two, because the binding property of auxiliary agent has limited the flowability of fine particle effectively, obviously reduce the flying dust phenomenon, played and reduced dust and the big effect of irritating smell, purified operating environment, obviously reduced stimulation and murder by poisoning degree, had good benefits in environment human body.Three, owing to the good stability of auxiliary agent, the large and small steady state that all is in of the particle of parcel has been eliminated because the small-particle vat powder easily decomposes rotten defective, has strengthened the stability of product, and the prevented from caking inefficacy has prolonged storage period.Four,,,, place that flowability improves after 24 hours though flowability is a little than the common product difference during blowing so hardness is better at normal temperatures for the outer parcel of vat powder because the solidification value of auxiliary agent is higher.Five, because the package action of vat powder behind the chance water, at first is that shell is earlier water-soluble, provide favourable guarantee for avoiding vat powder to decompose, so in the dissolving use, reduced the SO that decomposes generation by the interface
2Smell has improved the effective rate of utilization of vat powder, for client's consumption reduction provides favourable condition.Six, compounding agent solution adds that to be selected in the qualified latter stage of washing and filter pressing be because vat powder production at this moment is in SOT state of termination, does not have other unfavorable factor to package action fully, and is respond well.Seven, no dust vat powder constant product quality, technical maturity have overcome the inner quality defective of regular grade vat powder product preferably, have improved the stability of product, play the effect that guarantees HUMAN HEALTH, three-waste free discharge.
Embodiment: embodiment 1, the alkoxide polymer production that a kind of usefulness contains hydroxyl does not have method of dust vat powder and products thereof, material after synthesizing in the synthetic vat powder method of sodium formate method, filter through four unification moisture eliminators, washing, dry, cooling, piece together mixed back and obtain not having the dust vat powder, the compounding agent solution that after washing, adds the alkoxide polymer that contains hydroxyl, wherein, the preparation of compounding agent solution is: weigh polyoxyethylene glycol 20kg, methyl alcohol 500L carries out following operation: at first open auxiliary agent preparation pot hand hole plate, add weighing and polyoxyethylene glycol through crushing, close hand hole plate, feed P=0.30MPa to auxiliary agent preparation pot, the nitrogen replacement of content 〉=99.5% 3-4 time, the methyl alcohol 500L that in pot, adds weighing under the normal pressure, close pot last all valves, open and stir, open the chuck hot-water valve and be warming up to 60 ℃, stir 10min, auxiliary agent is dissolved fully.The interpolation of compounding agent solution is: the compounding agent solution for preparing is joined in the material that washing is good in four unification moisture eliminators, behind the static immersion 3min, auxiliary agent and material are fully contacted reach abundant bonding parcel, the nitrogen of using 0.3MPa, content 〉=99.5% then is the compounding agent solution press filtration, carries out drying, cooling, the assembly even back blowing that is mixed by normal drying program again and is packaged as finished product.Going distillation to reclaim methyl alcohol behind during the compounding agent solution of press filtration goes and the post again reuses for producing.
