Problems solved by technology

However, nonylphenol-type reactive emulsifiers have difficulty in biocompatibility and related environmental problems
With the improvement of national environmental protection requirements, the application of such products has been restricted
[0005] In addition, some reactive emulsifiers have too many reaction sites, which may also lead to unsatisfactory performance of the product

Embodiment 1

[0084]The molar ratio of hydrogenated cardanol to allyl glycidyl ether is 1 / 1.05, weigh 200g of hydrogenated cardanol (actually measured hydroxyl value 184.24mgKOH / g) with a moisture content (<1000ppm) into the reactor, and add 0.92gNaH , under the protection of nitrogen, stir and heat up to 90°C. Slowly add a total of 86.65 g of allyl glycidyl ether to the reaction kettle dropwise, the dropwise addition is completed within 1 hour, continue to stir for 8 hours, lower the temperature, and take a sample of 1-1#.

Embodiment 2

[0086] With reference to the method of Example 1, the molar ratio of hydrogenated cardanol and allyl glycidyl ether is 1 / 1.05. Weigh 255g of hydrogenated cardanol into the reaction kettle, add 1.15g of NaH, stir and raise the temperature to 90°C under the protection of nitrogen. Slowly add a total of 108.1 g of allyl glycidyl ether to the reaction kettle dropwise, and the dropwise addition is completed within 1 hour, continue to stir for 4 hours, and take a sample of 1-2#-1; continue to stir and react until 8 hours, and take a sample of 1 -2#-2 samples.

Embodiment 3

[0088] With reference to the method of Example 1, the molar ratio of hydrogenated cardanol and allyl glycidyl ether is 1 / 2.0. Weigh 300g of hydrogenated cardanol into the reaction kettle, add 1.35g of NaH, stir and raise the temperature to 80°C under the protection of nitrogen. Slowly add 130g of allyl glycidyl ether dropwise to the reaction kettle, the dropwise addition is completed within 1 hour, continue to stir for 4 hours, lower the temperature, take a sample of 1-3#-2, continue to stir for 8 hours, and take a sample of 1-3#-2 3#-1 sample.

Abstract

The invention provides a hydrogenated reactive emulsifier with excellent stability and water resistance and its preparation method and application. The hydrogenated cardanol or hydrogenated cardanol polyether side chain used does not contain double bonds and has moderate reactivity. The reactive emulsifier is a compound containing the structure shown in formula (I): the reactive emulsifier provided by the present invention can react more effectively with the polymerized monomer, so that the obtained polymer emulsion has excellent stability and composition membrane water resistance.

Description

technical field [0001] The invention belongs to the field of surfactants, and in particular relates to a hydrogenation reaction emulsifier with excellent stability and water resistance, a preparation method and application thereof. Background technique [0002] Emulsion polymerization is a common method for preparing high-molecular-weight, water-based polymer dispersions. The obtained polymer emulsions are widely used in industrial fields such as building interior and exterior wall coatings, adhesives, and paper sizing agents. Emulsifiers refer to surfactants that can stabilize emulsions, and are widely used in food, daily necessities, chemical and other industries. In the emulsion polymerization process, the main function of the emulsifier is to provide a place for nucleation, reaction and growth of the polymer particles, to stabilize the heterogeneous polymerization reaction process, and to ensure the dispersion stability of the emulsion product during storage and transpor...
