Embodiment 1

[0020] Based on 100 parts by weight, get 60 parts of 40wt% CaCl 2 Aqueous solution, 5 parts of C12EO9, 5 parts of AES, 1.6 parts of n-butanol, 28.4 parts of 5# white oil. Then put them together in a reactor and mix evenly, and stir at a speed of 300 rpm for 12 minutes at normal temperature to form a microemulsion type oil stain cleaning agent.

[0021] Investigate the solubilization ability of the microemulsion type cleaning agent of the prepared microemulsion type cleaning agent to other types of oil phases of high temperature stability, long-term stability, low temperature stability and microemulsion type cleaning agent respectively according to the following methods:

[0022] 1. Stability measurement:

[0023] Long-term stability: Place the product statically for a long time, observe the appearance, and pay attention to whether there is a clear delamination.

[0024] High-temperature stability: Place the sample in a high-temperature roller heating furnace at 120°C for 15-...

Embodiment 2

[0031] Based on 100 parts by weight, take 55 parts of 50wt% NaCl aqueous solution, 10 parts of a mixture of Span60 and Tween20 in a weight ratio of 1:1, 5 parts of SDS, 3 parts of ethanol, and 27 parts of diesel oil. Then put them together in a reactor and mix them evenly, and stir at a speed of 50 rpm for 20 minutes at normal temperature to form a microemulsion type oil stain cleaning agent.

[0032] Investigate the feature of microemulsion type cleaning agent by the method of embodiment 1, data is as follows:

Abstract

The invention discloses a micro-emulsion type oil stain cleaning agent and a preparation method thereof. The micro-emulsion type cleaning agent comprises 55-84 parts of inorganic salt aqueous solution with concentration of 20-50wt%, 5-10 parts of nonionic surfactant, 5-10 parts of ionic surfactant, 1-3 parts of cosurfactant and the balance of oil phase based on 100 parts by weight. The preparation method comprises the steps of uniformly mixing the ionic surfactant, nonionic surfactant and cosurfactant with the inorganic salt aqueous solution to obtain a mixed liquid, dropwise adding the oil phase into the mixed liquid under a room-temperature stirring condition, and standing to obtain the micro-emulsion type oil stain cleaning agent. The micro-emulsion type cleaning agent disclosed by the invention is formed under a high-salt concentration condition and has the advantages of good long-term stability, high-temperature stability and low-temperature stability; meanwhile, a small quantity of surfactant is required, the solubilizing ability on various types of oil phases is strong, and a good cleaning effect is realized on polar and non-polar oil stains.

Description

technical field [0001] The invention relates to a microemulsion-type universal oil stain cleaning agent for effectively removing grease and dirt under high calcium salt conditions and a preparation method thereof, belonging to the technical field of oil stain cleaning agents. Background technique [0002] In recent years, general-purpose liquid detergents have been widely used to clean oil stains on metal surfaces. Generally speaking, such detergents are used in normal temperature and low-salinity conditions, but in high-temperature, high-salt environments, ordinary detergents The cleaning effect is not obvious or even loses the cleaning effect. In addition, this type of cleaning agent has a large amount of active ingredients, a complex formula, and high raw material prices, which have great limitations in practical application. [0003] Compared with other types of cleaning agents, microemulsion cleaning agents have extremely low interfacial tension and strong solubilizing...
