Problems solved by technology

Polymer emulsifier (T152), as the most typical polybutene succinimide emulsifier, is often used in combination with SPAN-80 in production, but the inventors found through research that the stability of the emulsifier after compounding Still unsatisfactory, so it is of great significance to invent a polybutene succinimide emulsifier with better stability

Embodiment 1

[0045] 82.4g (0.08mol) of polyisobutylene succinic anhydride (Mn=1030g / mol) with a saponification value of 108.86mg / gKOH, 33.0g of base oil were put into the reactor, and N,N-dimethyl-1,3-propane Add 8.0g (0.078mol) of diamine to the dropping funnel, stir, heat up to 40°C, add N,N-dimethyl-1,3-propanediamine dropwise, after the dropwise addition, continue to react for 1.0h, Raise the temperature to about 130~150°C, and under the vacuum degree of 0.08MPa, when the acid value is basically unchanged, the reaction is ended to obtain polyisobutylene succinimide, and 5.7g of base oil is added to make the base oil account for the weight of the mass. 30% of.

[0046]Put 79.5g (0.05mol) of the polyisobutylene succinimide product prepared above into the reactor, add 8.5g (0.055mol) of diethyl sulfate into the dropping funnel, stir, raise the temperature to about 80°C, and add sulfuric acid dropwise After the diethyl ester is added dropwise, continue to react until the amine value is su...

Embodiment 2

[0048] Put 79.5g (0.05mol) of polyisobutylene succinimide prepared according to the method described in Example 1 into the reactor, add 6.1g (0.055mol) of 3-chloro-1,2-propanediol into the dropping funnel, and stir , the temperature was raised to about 80°C, and 3-chloro-1,2-propanediol was added dropwise. After the dropwise addition, the reaction was continued until the amine value was basically unchanged, and the reaction was ended to obtain the emulsifier P2, and 2.6g of base oil was added. , so that the active matter content is about 70%.

Embodiment 3

[0050] Put 82.4g (0.08mol) of polyisobutylene succinic anhydride (Mn=1030g / mol) with a saponification value of 108.86mg / gKOH, and 80g of n-octane into the reactor, and put N,N-dimethyl-1,3-propane Add 9.0g (0.088mol) of diamine to the dropping funnel, stir, heat up to 50°C, add N,N-dimethyl-1,3-propanediamine dropwise, after the dropwise addition, continue the reaction for 0.5h, Raise the temperature to about 130°C, under the vacuum degree of 0.04MPa, and react until the acid value is basically unchanged, the reaction is terminated, and the solvent is removed to obtain polyisobutylene succinimide.

[0051] Put 55.7g (0.05mol) of polyisobutylene succinimide prepared above, 60g of n-octane, and 30g of isopropanol into the reactor, dissolve 7.0g (0.06mol) of sodium chloroacetate with 15g of water, and add it dropwise Liquid funnel, stirring, heating up to about 80°C, dropwise adding sodium chloroacetate solution, after the dropwise addition, continue to react until the amine valu...

Abstract

The invention provides a polyisobutylene succinimide quaternary ammonium salt emulsifier and a preparation method thereof. The preparation method comprises the following steps: performing amination reaction on polyisobutylene succinic anhydride and an amination reagent to obtain polyisobutylene succinimide; and then, performing quaternization reaction on the polyisobutylene succinimide and a quaternization reagent to obtain the polyisobutylene succinimide quaternary ammonium salt emulsifier. The emulsifier has fine stability quality and is used for the preparation of an emulsion explosive in the emulsion explosive industry.

Description

technical field [0001] The invention relates to an explosive emulsifier, in particular to a polyisobutylene succinimide quaternary ammonium salt emulsifier for producing emulsion explosives and a preparation method thereof. Background technique [0002] The emulsifier plays a key role in the emulsion explosive. The emulsifier makes the oxidant water phase and the fuel oil phase form a water-in-oil emulsion explosive matrix. The performance of the emulsifier determines the explosive performance and storage performance of the emulsion explosive. [0003] At present, the emulsifiers widely used in the production of emulsion explosives are mainly SPAN-80 and polybutylene succinimide (single-hang, double-hang and multi-hang) emulsifiers. The advantage of SPAN-80 is that it is easy to emulsify, that is, it can be emulsified at a relatively low speed, but its molecular structure contains double bonds, which are easy to demulsify and crystallize after being oxidized, so that the emu...
