Problems solved by technology

Generally speaking, as the operating temperature decreases, the difference in gel concentration will also increase. Therefore, in high-latitude frigid countries, surfactants with a large difference in gel concentration are easy to gel and solidify, and are not easy to dilute. more limited applicability

Embodiment S-1

[0066] First, 160g (1.0mole) of isodecyl alcohol (manufactured by ExxonMobil Chemical Company, and the product model is Exxal 10, its carbon number distribution is C9: 4%; C10: 89%; C11: 7%), 149g (1.0 mole) of butyl glycidyl ether (butyl glycidyl ether) and 114 g (1.0 mole) of allyl glycidyl ether (allyl glycidylether) were added to the reaction flask, and a ring-opening reaction was carried out to obtain a second intermediate product. Then, 440 g (10.0 mole) of ethylene oxide was added to the second intermediate product, and an addition reaction was performed. After the addition reaction is over, sulfamic acid is added to carry out the esterification reaction. After the esterification reaction is completed, add ammonia water and carry out neutralization reaction to obtain a polymerizable surfactant represented by the following formula (III-1). The obtained polymerizable surfactant was evaluated by the following evaluation method of gelation evaluation, and the obtained resu...

Embodiment S-2 to S-6

[0069] The preparation method of the polymerizable surfactant of embodiment S-2 to S-6 is to use the same synthetic steps as the preparation method of the polymerizable surfactant of embodiment S-1, the difference is that embodiment S- 2 to S-6 are to change the type and amount of reactants. Wherein, the polymerizable surfactants prepared in Examples S-2 to S-6 respectively have the structures shown in the following formulas (III-2) to formulas (III-6). The obtained polymerizable surfactants were evaluated by the following evaluation methods of gelation evaluation, and the obtained results are shown in Table 1-1.

Abstract

The present invention relates to a polymerizable surfactant as shown in formula (I): R 1 Represents an alkyl group having a branched chain structure with 8 to 13 carbons, an alkenyl group with 2 to 5 carbons, phenyl, o-phenylphenyl, styrenated phenyl or styrenated o-phenylphenyl. S 1 represents a single bond or an alkoxy segment, and S 2 Represents an alkoxy segment. The alkoxy segments are respectively composed of at least one alkoxy group, and the alkoxy group is selected from a group consisting of ethoxy, propoxy, butoxy and any combination thereof. in S 1 or S 2 In , the number of alkoxy groups is 1 to 100, respectively. R 2 Represents an alkyl, phenyl or tolyl group with 1 to 4 carbon atoms. R 3 Represents an alkenyl group having 2 to 4 carbon atoms. R 4 Represents a hydrogen atom or an anionic group. x represents an integer of 0 to 3, and y represents an integer of 1 to 3. The prepared polymerizable surfactant has a smaller gel concentration difference.

Description

technical field [0001] The invention relates to a polymerizable surfactant, in particular to provide a polymerizable surfactant with a smaller gel concentration difference and its application. Background technique [0002] In order to comply with the current international environmental protection regulations and reduce the emission of volatile organic compounds (Volatile Organic Compounds; VOCs), traditional oil-based paint resins are gradually replaced by water-based paint resins. However, some properties of water-based coating resins are still not comparable to oil-based coating resins, such as water resistance or weather resistance. The reason is that in the manufacturing process of emulsion polymerization, emulsifiers must be added to water-based paints, but emulsifiers do not have functional groups that can react with monomers, so as the use time increases, the emulsifiers in the resin coating film will migrate. to the surface of the resin, and reduce the related physi...
