Abstract

The present invention relates to the multifunctional surfactant for pressure-sensitive adhesive as shown in the following chemical structural formula, Among them, R 1 for C 5 ~C 10 Saturated branched chain hydrocarbon group, R 2 for C 8 ~C 18 Saturated straight chain hydrocarbon group, R 1 with R 2 different; a=0~10, b=2~10, c=0~10, d=2~25, are all integers; M is selected from Li + , Na + , K + , NH 4 + one or more of them. It also relates to a method for preparing a multifunctional surfactant for pressure-sensitive adhesives, comprising the following steps: 1) carrying out monoesterification of alcohol ether and maleic anhydride; and 3) sulfonating the product obtained in step 1) to obtain the final product. In the molecular design of the present invention, branched chain hydrocarbon groups are used to provide osmotic wettability, straight chain hydrocarbon groups provide emulsifying ability, and EO and PO blocks provide defoaming and antifoaming properties. The synthesis method of the invention is simple, easy to operate, less harmful to the environment, and simultaneously provides wetting, emulsifying and defoaming properties, and has wide application prospects in the field of pressure-sensitive adhesive emulsions.

Description

technical field [0001] The invention relates to a multifunctional surfactant for pressure-sensitive adhesives and a preparation method thereof, belonging to the field of gemini surfactants. Background technique [0002] Gemini surfactant molecules contain two or more hydrophilic groups and hydrophobic groups, which are chemically bonded by an intermediate linking group (Spacer) to form a new type of surfactant. Compared with traditional surfactants, Gemini surfactants usually have the following characteristics: [0003] Gemini surfactants are more likely to aggregate into micelles, that is, have a rather low CMC value, and are more suitable for use as emulsifiers and dispersants. This is mainly due to the fact that the two ionic head groups connected by chemical bonds in the molecule are tightly connected, which makes the hydrophobic groups have a strong interaction and inhibits the separation caused by the electrostatic repulsion between the hydrophilic ionic head groups. ...
