Embodiment 1

[0035] Embodiment 1 A kind of preparation method of penetrating agent

[0036] This example is a preparation method of a penetrating agent, which is obtained by esterification and sulfonation of polyether-modified silicone oil maleate in sequence, and the specific steps are carried out in the following order:

[0037] (1Ⅰ) Preparation of Polyether Modified Silicone Oil Maleate

[0038] In a four-necked flask filled with toluene, add polyether-modified silicone oil and maleic anhydride with a molar ratio of 1:1.2. After they are all dissolved, react for 8 hours at 30°C with stirring, stop heating, and remove toluene and residual maleic anhydride. Acid anhydride, cooling and discharging, to obtain a liquid product, the obtained polyether modified silicone oil maleate structural formula is as follows, denoted as A1;

[0039]

[0040] m is an integer of 0-10; n is an integer of 3-53.

[0041] (1Ⅱ) Preparation of penetrant

[0042] (11) In the reactor, add A1, polyoxyethylene...

Embodiment 2-5

[0045] The preparation method of embodiment 2-5 penetration agent

[0046] Examples 2-5 are a preparation method of a penetrating agent, the preparation method is similar to that of Example 1, the only difference is that the corresponding technical parameters in the preparation process are different, as shown in the following table.

Abstract

The invention discloses a penetrant and a preparation method thereof. In the structure of the penetrant, a polyether modified silicone oil side chain, sulfonate and a polyoxyethylene ether chain are introduced; the penetrant has low foaming and defoaming properties, can be well dispersed in water, has good compatibility with other solvents, and has good wettability. The invention further disclosesthe preparation method of the penetrant. The penetrant is prepared by sequentially esterifying and sulfonating polyether modified silicone oil maleate. The preparation method is simple, the process is easy to control, the cycle is short, and a prepared product is high in purity. The preparation method is applicable to preparation of the penetrant.

Description

technical field [0001] The invention belongs to the field of polymer synthesis, and in particular relates to a penetrating agent and a preparation method thereof. Background technique [0002] Penetrant refers to a class of chemicals that can help the substance that needs to penetrate to penetrate the substance that needs to be penetrated. It has good stability and penetration. In the industry, surfactants, organic or inorganic solvents, or a variety of A complex mixture of surfactants and solvents. Its main function is to reduce interfacial tension, increase absorption and permeability, and is widely used in various industries. [0003] However, the existing penetrating agent has poor compatibility, especially when used with other solvents, the penetrating effect is poor, and more foam is generated, which directly affects the penetrating effect and the quality of the final product. Contents of the invention [0004] The purpose of the present invention is to provide a p...
