Description

Dressing non-primer mixture nail shooting pill tablet formula and preparation method thereof
Technical field
The present invention relates in a kind of nailing ammunition technical field about formula of dressing non-primer mixture nail shooting pill tablet and preparation method thereof.
Background technology
Non-primer mixture nailing ammunition in the market, when use in physical environment, storage, the degradation such as percussion rate, power of product is easily made because of the tablet moisture absorption, the easy moisture absorption is there is in storage, use, transportation, percussion poor performance, causes machinery percussion sensitivity low, the problem of work reliability difference, and the security of production process is poor, very easily pyrophoricity accident occurs.In the technological process of production adopted, for obtaining the material of certain granules degree, after carrying out gel, need sieve material material, the material after screening needs to be dried by moisture to very low state (less than 3%) ability compression molding.But often size is uneven to sieve the granular material that obtains, and containing a large amount of soluble cotton dust, cause drying and the material dust of compression molding is many, moisture is low, easily causes breakneck combustion explosion accident, manufacturability and poor stability.China Patent No. ZL9711769.9 disclosed " non-primer mixture nailing ammunition " and " film-covered nail shooting pill " disclosed in 201120287439.9 (publication number CN202192601U), due to and unresolved machinery percussion sensitivity low, percussion poor performance problem and can not come into the market smoothly; Although China Patent No. ZL200410016637.6 improves patent and with the addition of the sensitive materials such as oxygenant, metalliferous mineral particle, priming explosive, but still there is safety issue; Although China Patent No. 201210188018.X (publication number CN102675007A) " preparation method of the non-primer mixture powder charge of high mechanical sensitivity ", soluble cotton is mixed with the aqueous solution and carries out prilling process, solve the low problem of sensitivity and safety issue, but there is manufacturability issues and can not produce in batches.
Summary of the invention
The object of the invention is the weak point existed for prior art, there is provided a kind of soluble cotton dust content lower, dust pollution is few, humidity resistance is excellent, easy and simple to handle, process safety, without the need to carrying out the preparation method of the dressing non-primer mixture nail shooting pill tablet of screening operation, to solve in existing minimizing non-primer mixture nailing ammunition preparation technology engineering, easily there is the problem of the easily moisture absorption in the safety problem of blast accident and use procedure, storage process.
In order to the non-primer mixture nail shooting pill tablet formula and preparation method that to solve in existing non-primer mixture nailing ammunition preparation technology engineering the easily problem of the moisture absorption in safety problem that blast accident easily occurs and use procedure, storage process can be achieved through the following technical solutions:
Dressing is without a percussion projectile nail tablet preparation formula, and this propelling charge composition is composed of the following components by weight percentage:
Described moisture is moisture residual in technique preparation process, and tranquilizer, binding agent, solvent all add in gel (plasticizing) operation, and coating material adds at enrobing processes.
Prepare the method for described dressing without percussion projectile nail tablet, it is characterized in that comprising the steps: that concrete step is as follows:
Obtain solution: soluble cotton presses any value of 89.80wt% ~ 99.78wt% scope, weigh the soluble cotton that moisture content content is 20wt% ~ 40wt%, with total amount, by the tranquilizer of 0.20wt% ~ 0.75wt%, the binding agent of 0.01wt% ~ 0.45wt%, consumption is that 20wt% ~ 80wt% solvent dissolves, and is mixed with tranquilizer solution, binder solution; Then the above-mentioned solution prepared is dropped in gel kneader, gel 30min ~ 60min; Again by the above-mentioned gel material prepared, put into pressure stretch machine equipment, companding shaping is even-grained granular material; Adopt drying plant, preparation granular material dry with 40 DEG C ~ 70 DEG C bake out temperatures, dry to moisture content be 3wt% ~ 15wt%; The material drying particle of gained is suppressed on tabletting machine, and compression molding is sheet tablet; The tablet of preparation joins in coating pan; In tablet fill weights, adopt the coating material of 0.01wt% ~ 3.0wt% and compound concentration be the coating liquid even application of 1wt% ~ 5.0wt% at coat tablets, form one deck moisture-proof film at coat tablets.
The present invention has following beneficial effect compared to prior art:
(1) the present invention selects one or more in hydroxyl cellulose acetate butyrate (CAB), polyvinylpyrrolidone (PVP), cellulose acetate phthalate (CAP) as coating material, and the humidity resistance of obtained non-primer mixture nail shooting pill tablet is excellent.
(2) the present invention selects the pressure stretch machine equipments such as oil press, water pressure engine, screw compress machine to carry out shaping to gel material, the granular material size obtained is even, good fluidity, and outside material, wave (moisture)≤15wt%, the condition of compression molding can be met, wave outside gel material compared to prior art nail shooting pill pharmaceutical worker skill and must control at≤3wt%, can the moisture content of compression molding few, and soluble cotton dust content is lower in the granular material obtained, dust pollution is few, easy and simple to handle, process safety.This technique being waved moisture by improving outside material, being decreased dust, solves the process safety sex chromosome mosaicism existed in subsequent handling, inherently improves process safety.
(3) the present invention adopts gel, companding shaping, first drying, compression molding, dressing, secondary drying, obtained product tablet size and the consistence of density good, support the use in nailing fastening equipment use properties reliable.
(4) the present invention is on ZL9711769.9 patent No. basis, with moisture soluble cotton for base-material, by adding moisture soluble cotton, solvent, tranquilizer, binding agent in gelling machine (kneader), after mixing certain hour, complete gel, then particulate state is compressed to by pressure stretch machine, again by after its first drying, tabletting machine is adopted to be shaped to tablet, finally the tablet after shaping is added in coated pot, coating material is adopted to carry out dressing, after its secondary drying, namely composition and engineering obtained of the present invention improves obtained dressing without percussion projectile nail tablet, preparation technology's security is good and tablet humidity resistance is excellent, solve the easy moisture absorption of non-primer mixture nailing ammunition, percussion poor performance, the manufacturability of production process and safety issue, obtained dressing is high without percussion projectile nail medicine percussion rate, power is large, percussion rate reaches 100wt%, when using the A3 steel plate that the YD nailing shooting thickness that head of a nail diameter is 8mm is 8mm, its shooting degree of depth can reach more than 15mm.
The present invention is different from patent of invention 201210188018.X (publication number CN102675007A) " preparation method of the non-primer mixture powder charge of high mechanical sensitivity ", do not need soluble cotton to be mixed with the aqueous solution and carry out granulation, do not need to carry out screening operation, but by improving nail shooting pill tablet composition and engineering, the mode coated by kneader gel mixture, companding shaping, coating material improves technique.
The film-covered nail shooting pill that the present invention is also different from described in patent of invention " film-covered nail shooting pill " is different from the preparation technology of dressing non-primer mixture nail shooting pill tablet prepared by this patent, and coating material of the present invention is not within the protection domain of patent " film-covered nail shooting pill ".
