preparation example Construction

[0016] Further, the preparation method of castor oil waterborne shape memory polyurethane comprises:

[0017] Weigh 5-8 parts by mass of castor oil, 5-8 parts of isophorone diisocyanate, 0.2 parts of catalyst, 0.5-3 parts of 2,2-dimethylolpropionic acid and 0.4-0.8 parts of triethylamine;

[0018] Mix castor oil and isophorone diisocyanate, add catalyst, feed nitrogen, react at 60-80°C for 1-3 hours, the mass of catalyst added is 40-60% of the total amount of catalyst weighed ;

[0019] Cool down to 40-50°C, add acetone, 2,2-dimethylolpropionic acid and the remaining catalyst, react at 40-50°C for 0.5-1.5 hours, the amount of acetone added is 50-100% of the total volume of the reaction system ;

[0020] Cool down to 20-30°C, add triethylamine, react for 20-40 minutes, add water to obtain castor oil water-based shape-memory polyurethane.

[0021] Specifically, the catalyst is at least one of dibutyltin dilaurate and stannous octoate.

[0022] Specifically, the betaine-type ...

Embodiment 1

[0027] 1. Preparation of castor oil waterborne shape memory polyurethane

[0028] Add 6.883g of castor oil and 6.766g of isophorone diisocyanate (IPDP) into a 500mL three-neck round bottom flask, add 0.1g of dibutyltin dilaurate, blow in nitrogen, and react at 70°C for 2 hours.

[0029] Cool down to 50°C, add 120mL of acetone, 1.8g of 2,2-dimethylolpropionic acid and 0.1g of dibutyltin dilaurate catalyst, and react at 50°C for 1h.

[0030] Cool down to 30°C, add 0.6g triethylamine to react for 30min to neutralize the unreacted acid, add 60mL distilled water dropwise under high-speed stirring at 1000rpm to obtain a blue and transparent clear solution, remove acetone from the solution through a rotary evaporator, and obtain a solid content of approx. 25 wt% aqueous shape memory polyurethane emulsion.

[0031] Then, the above water-based shape-memory polyurethane emulsion was used as the main raw material, and distilled water was added to obtain water-based shape-memory polyuret...

Abstract

The embodiment of the invention provides an ironing agent, and relates to the technical field of clothing. The ironing agent is prepared from the following components in parts by mass: 1 to 5 parts ofcastor oil waterborne shape memory polyurethane, 0.5 to 2.5 parts of high-molecular fatty alcohol, 0.5 to 1 part of betaine-ionic surfactant and 91.5 to 98 part of water. When fabrics are ironed, theironing agent is uniformly sprayed onto the fabrics, and then the fabrics are ironed and dried; when the fabrics are deformed, a temperature is heated to an ironing agent resin transition temperatureor above, and the fabrics are quickly restored into an original shape under an effect of the shape memory, namely, an even state, so that shape maintenance and wrinkle resistance of the fabrics are realized.

Description

technical field [0001] The invention belongs to the technical field of clothing, in particular to an ironing agent and a preparation method thereof. Background technique [0002] Clothing is a necessity in people's lives. With the improvement of people's living standards, the requirements for clothing are getting higher and higher, such as the shape and shape of clothing. In fact, after the clothes are worn for a long time and washed for a long time, the clothes will become soft or wrinkled, which greatly affects the appearance. Usually ironing will improve the wrinkled state of clothes. However, the traditional ironing method is to spray clear water onto the surface of the clothes and use high temperature to make the fabric of the clothes flat, but the clothes can only be kept flat in a short time. [0003] In order to solve the above problems, oligomers or organic compounds are mainly used as ironing textile auxiliaries in the prior art, such as silicone gel or sodium ca...
