Description
The present invention relates to a kind of tensio-active agent that is used to improve the inorganic salt performance, particularly a kind of compound crystal modifier that is used to improve the inorganic salt performance.
Ammonium nitrate is a kind of water absorbability and the very strong inorganic salt of anti-caking, and has bad brilliant sex change energy and insensitiveness performance, thereby has influenced the result of use of ammonium nitrate.When especially it being used as the oxygenant of explosives, the blast performance and the use properties of explosives will be influenced directly.Other many inorganic salt as nitrate, perchlorate, vitriol, phosphoric acid salt etc., also have above-mentioned defective to some extent.For a long time, the problems referred to above have been carried out a large amount of research both at home and abroad, successively adopted several different methods, the method for wherein adding tensio-active agent can be improved some performance of inorganic salt to a certain extent.But owing to adopt the tensio-active agent of single variety, its effect is partial, limited.
The objective of the invention is to propose a kind of NEW TYPE OF COMPOSITE crystal modifier for the shortcoming that overcomes present technology.Compound crystal modifier of the present invention combines with various inorganic salt, can significantly reduce anti-caking, the water absorbability of inorganic salt, improves brilliant sex change, improves susceptibility.The present invention is applicable to the improvement to various inorganic salt performances.
The compound crystal modifier that designs according to the present invention is characterized in that containing (quality %): 10～90 conventional surfactants, 5～80 lipid acid or (with) fatty acid metal salt, 2～10 organic hydrophobic agents; Conventional surfactants is an alkylamine salt, the mixture of one or more in the carboxylate salt of alkyl or alkylbenzene, vitriol, sulfonate or the carbonate; Lipid acid or (with) fatty acid metal salt is C
12～C
18Lipid acid or (with) their metal-salt of zinc, aluminium, calcium, sodium etc.; Organic hydrophobic agent is paraffin, pitch, machine oil, silicone oil, ceresine, Vaseline, rosin etc. and their mixture.Wherein conventional surfactants be octadecane amine or (with) one or both mixtures in the acetate of n-Laurylamine, dodecane sulfonate, dodecylbenzene sulfonate; Lipid acid or (with) soap is: stearic acid, Palmiticacid or (with) one or more mixtures in their zinc, calcium, aluminium, sodium salt.
The principle of design of compound crystal modifier of the present invention is: inorganic salt all are strong polar materials, and very high surface energy is arranged, and this is the basic reason of their moisture absorptions, caking etc.Conventional surfactants all has " amphiphilic " constructional feature, and when hydrophilic group acted on the inorganic salt surface molecular, oleophilic group pointed to extraneous; So form one deck hydrophobic nature " film " at particle surface, permeate when crystal grain is inner when conventional surfactants, reactive force between disturbing molecule changes the inorganic salt crystalline form; " stratiform ", " tubulose " or " pencil " of tensio-active agent in inorganic salt solution arranged, and can change crystallization direction and shape effectively, makes to separate out crystalline intensity and bonding force reduction.Utilize this principle, finiteness at single Action of Surfactant, compound crystal modifier of the present invention adopts two or more conventional surfactants and organic hydrophobic agent to form, their coefficient results, make the inorganic salt particle surface set up fine and close, multilayer hydrophobic nature " film ", effect to the inorganic salt crystals is further strengthened, thereby has very strong modifying function, and the inorganic salt original physical properties is better improved.When if the present invention is used for inorganic salt, be aided with suitable pressure crystallization condition, wherein moisture is vaporized rapidly, is overflowed, and then forms the inorganic salt particle that inside is full of self sensitization of " air gap ", surface imperfection.So the present invention is specially adapted to do the crystal modifier of the inorganic salt of explosive oxygenant.
The present invention compared with prior art, its distinguishing feature is: (1) adopts kinds of surface promoting agent and hydrophober, the effect that the inorganic salt physicals is improved is very remarkable.For example, ammonium nitrate with compound crystal modifier processing of the present invention, cake strength only is 1/12～1/20 of a common ammonium nitrate, and rate of moisture absorption is reduced to 1/6～1/10 of common ammonium nitrate, and the brilliant alternating temperature degree of ammonium nitrate III ()/() IV phase is changed into 52～56 ℃ by 32.1 ℃; (2) inorganic salt after the modification act on suitable susceptibility to external world, make powder ammonium nitrate explosive as modified ammonium nitrate, also have the blast performance of cap-sensitivity, high explosion velocity and high-power when not containing sensitizing agent; (3) compound crystal modifier technology is simple, reliable, and cost reduces about 20% than single tensio-active agent, is convenient to suitability for industrialized production and application.
Concrete prescription of the present invention and technology are provided by following examples.
The compound crystal that the present invention proposes is that the various starting material that properties-correcting agent adopts all meet the Ministry of Chemical Industry's part of standards or company standard.
