Embodiment 1

[0008] (1) Adjust the temperature of the reactor to 68°C. After the temperature is stable, add 3kg of octadecyldimethyl tertiary amine, 3kg of dimethyl polysiloxane, and 5kg of isopropanol into the reactor. Stir, the speed of the mixer is 300rpm, and the stirring time is 24min; (2) After the stirring is completed, add 2kg of sodium palmitate and 3kg of acrylic acid to the reaction kettle, stir again, the speed of the mixer is 350rpm, and the stirring time is 26min; (3 ) Then add 150kg of water, and use a shearing machine for shearing treatment. The processing time is 5 minutes, and the rotational speed of the shearing machine is 4000rpm; (4) After the shearing, the finishing agent is cooled to room temperature to obtain a water-repellent finishing agent.

Embodiment 2

[0010] (1) Adjust the temperature of the reactor to 70°C. After the temperature is stable, add 2kg of octadecyldimethyl tertiary amine, 4kg of dimethyl polysiloxane, and 4kg of isopropanol to the reactor, and use a mixer to Stir, the speed of the mixer is 300rpm, and the stirring time is 21min; (2) After the stirring is completed, add 4kg of sodium palmitate and 2kg of acrylic acid to the reaction kettle, stir again, the speed of the mixer is 350rpm, and the stirring time is 28min; (3 ) and add 145kg of water, and use a shearing machine for shearing treatment. The processing time is 5 minutes, and the rotational speed of the shearing machine is 4000rpm; (4) After the shearing, the finishing agent is cooled to room temperature to obtain a water-repellent finishing agent.

Embodiment 3

[0012] (1) Adjust the temperature of the reactor to 72°C. After the temperature stabilizes, add 3kg of octadecyldimethyl tertiary amine, 3kg of dimethylpolysiloxane, and 4kg of isopropanol to the reactor, and use a mixer to Stir, the speed of the mixer is 300rpm, and the stirring time is 18min; (2) After the stirring is completed, add 3kg of sodium palmitate and 2kg of acrylic acid to the reaction kettle, stir again, the speed of the mixer is 350rpm, and the stirring time is 30min; (3 ) Then add water to 148kg, and use a shearing machine for shearing treatment. The processing time is 5 minutes, and the rotational speed of the shearing machine is 4000rpm; (4) After the shearing, the finishing agent is cooled to room temperature to obtain a water-repellent finishing agent.

Abstract

The invention relates to a cotton clothes water repellent finishing agent and a preparation method, the cotton clothes water repellent finishing agent comprises the following components by weight ratio: 2-3 parts of octadeyl dimethyl tertiary amine, 3-4 parts of dimethyl polysiloxane, 4-5 parts of isopropanol, 2-4 parts of sodium palmitate, 2-3 parts of acrylic acid and 145-150 parts of water. The cotton clothes water repellent finishing agent of the present invention is prepared by stirring at high temperature and performing shear mixing. The cotton clothes water repellent finishing agent has good water repellency.

Description

technical field [0001] The invention relates to a water-repellent finishing agent and a preparation method thereof, in particular to a water-repellent finishing agent for cotton clothes and a preparation method thereof. Background technique [0002] In the daily wearing process of cotton clothing, water will often drip onto the cotton clothing. Ordinary cotton clothing does not have the function of water repellency. When moisture touches the cotton clothing, the cotton clothing will absorb water and affect people's normal wearing. By finishing the cotton clothes with a water-repellent finishing agent, the cotton clothes after finishing will have a certain water-repellent function. At present, there are many studies on improving the water-repellent performance of cotton clothes, but the cotton clothes finished by conventional water-repellent finishing agents still do not have good water-repellent performance. The patent publication number of CN101476242A discloses a pure cott...
