Problems solved by technology

The emulsifier currently used in industrial colloidal explosives is S-80 or polyisobutylene succinimide polymer emulsifier (the former has poor stability and the latter has insufficient emulsification), but due to the presence of oil in the production of industrial colloidal explosives phase and water phase, the density difference is large, and the acidity of the supersaturated solution of nitrate is low. On the other hand, due to the performance requirements of oxygen balance in industrial explosives, the addition of emulsifiers and oil phase materials is relatively low, resulting in the current existence of industrial colloidal explosives. Defects that need to be improved, such as poor emulsifiability during the process, high safety risks during emulsification, harsh emulsification conditions, and poor product stability

Abstract

The invention discloses a dimer acid emulsifier which is prepared from dimer acid, polyol, a catalyst, a diluent and polyamine or alcohol amine. The mass ratio of the dimer acid to the polyol is 100: (10-30); the addition amount of the catalyst is 0.01-0.1%. The dimer acid, the polyol and the catalyst react to obtain an intermediate containing a lipid group, namely dimer acid polyol ester, and the mass ratio of the dimer acid polyol ester to the polyamine or alcohol amine is 100: (5-40); the addition amount of the diluent is 50% of that of the dimer acid. Compared with the prior art, the emulsifier has the advantages that the emulsifier is used for industrial colloidal explosives, the emulsibility in the product preparation process is greatly improved, the emulsifier can be smoothly emulsified in the state of reducing the stirring strength in the emulsion preparation process, the emulsifier has a certain self-emulsifying function, and the stability of colloid is greatly improved after the emulsification is finished.

Description

Technical field [0001] The present invention relates to an emulsifier, and more particularly to a dimeric acid emulsifier. Background technique [0002] The dimeric acid is a dibasic acid produced by two molecules of C8 unsaturated fatty acids such as oleic acid, linoleic acid or the like, containing two polar carboxyl groups and a large non-polar hydrocarbon group, which chemistry The properties are similar to fatty acids, and there are two carboxyl groups in the molecule, and there are a variety of reactions such as lipidation, amination, and a large alkyl group in the molecule containing 1-3 double bonds, which can occur, polymerization and other chemical reactions. . Dimic acid is generally used in the field of resin, cosmetics, and the field of lubricating oil. Industrial colloidal explosives currently use the emulsifier for S-80 or polyisobutylntia -tyimide polymer emulsifier (poor stability in front, is not sufficiently emulsified), but due to industrial glue explosive pro...
