Embodiment 1

[0098] The molar ratio of isomeric carbooctaol (2-EH alcohol) and allyl glycidyl ether is 1 / 1.05, and 200g of 2-EH alcohol (measured hydroxyl value 431.5mgKOH / g) is weighed up to the standard (<1000ppm) ) into the reaction kettle, add 0.9gNaH, under the protection of nitrogen, stir and heat up to 90°C. Slowly add a total of 184.5 g of allyl glycidyl ether to the reaction kettle dropwise, the dropwise addition is completed within 1 hour, continue to stir for 8 hours, cool down to 50-60°C, and take a sample of 1-1#.

Embodiment 2

[0100] Referring to the method of Example 1, the molar ratio of 2-EH alcohol to allyl glycidyl ether is 1 / 1.05. Weigh 250g of 2-EH alcohol into the reaction kettle, add 1.13g of NaH, stir and raise the temperature to 90°C under the protection of nitrogen. Slowly add a total of 230.1 g of allyl glycidyl ether dropwise to the reactor, and the dropwise addition is completed within 1 hour, continue to stir and react for 4 hours, and sample 1-2#-1 sample; continue to stir and react for 8 hours, and sample as 1-2#-2 samples.

Embodiment 3

[0102] Referring to the method of Example 1, the molar ratio of 2-EH alcohol to allyl glycidyl ether is 1 / 2.0. Weigh 300g of 2-EH alcohol into the reaction kettle, add 1.35g of NaH, stir and raise the temperature to 80°C under the protection of nitrogen. Slowly add 526.8g of allyl glycidyl ether dropwise to the reaction kettle, the dropwise addition is completed within 1 hour, continue to stir and react for 4 hours, cool down, take a sample of 1-3#-2, continue to stir for 8 hours, and take a sample of 1-3#-1 sample.

Abstract

The invention relates to a reactive emulsifier and a preparation method and application thereof. The reactive emulsifier is a compound containing a structure as shown in a formula (I) which is described in the specification. The reactive emulsifier provided by the invention can be selectively made into a nonionic reactive emulsifier or an anionic reactive emulsifier according to actual demands soas to adapt to use under different conditions and occasions, can be independently used or matched with other reactive emulsifiers for use, and has the advantages of excellent water whitening resistance, favorable adhesive force, favorable freeze-thaw storage performance, favorable adaptability and wide application range.

Description

technical field [0001] The invention belongs to the field of surfactants, in particular to a reactive emulsifier and its preparation method and application. 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 architectural coatings, water-based wood paints, water-based industrial anti-corrosion paints, water-based inks and adhesives. 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 transportation.
