Problems solved by technology

The application of polysiloxanes in aqueous solutions can cause various problems during industrial applications due to the high shear forces of jet dyeing machines which often delaminate the emulsion when used in jet dyeing machines, forming silicone spots , pollute the textiles, increase the cost and difficulty of subsequent cleaning
[0003] At present, aminoalkylsilane and hydroxyl polysiloxane are used as raw materials to make aminopolysiloxane, which is widely used in various fabric finishing, although it can improve the appearance and flexibility of fabrics or leather goods, and increase the resistance of textiles or leather goods. Tear resistance, water resistance, oil resistance, more luster, etc. ([J]. Insulating Materials, 2006, 39(1): 59-63.), but the traditional aminopolysiloxane has poor wear resistance and still exists Poor hydrophilicity makes textiles have poor air permeability and other disadvantages

Embodiment 1

[0049] Embodiment 1, the preparation of compound (a1)

[0050] Reagents: Compound (a1) was purchased from Shenyao (Xianghe) Technology Co., Ltd.; Compound (b1) was prepared by referring to the method described in the patent US3971627A; LiClO 4 Purchased from Shanghai Zhongli Industrial Co., Ltd.

[0051] The synthetic route is as follows:

[0052]

[0053] Specific preparation method:

[0054] Dissolve 90 g of compound (a1) in 250 mL of warm THF (tetrahydrofuran), add 1 g of LiClO 4 and compound (b1), under the protection of nitrogen, control the temperature at about 150-200° C., heat to reflux, and react for 3 hours. After the reaction was complete, the mixture was filtered and the organic phase was separated. The obtained organic phase was washed successively with pure water and saturated sodium chloride, then dried with anhydrous sodium sulfate, and finally spin-dried to obtain compound (1a). The modified polysiloxane has a viscosity of about 350,000 mPa.S at 25° C....

Embodiment 2

[0059] Embodiment 2, the preparation of softening emulsion containing compound (a1).

[0060] Mix 20g of compound (a1) and 3mL of the compound of fatty alcohol polyoxyethylene ether AE09 and ester polyvinyl chloride ether SG-40 (1:2, w / w), and then add 4mL of hydrochloric acid, continue Stir until the pH range is 6-7; continue to stir the compound until a large amount of foam occurs, then slowly add 100 mL of water while stirring to obtain a microemulsion containing the compound (1a).

Embodiment 3

[0061] Embodiment 3, mechanical stability test

[0062] Sample: the sample of the comparative example was prepared according to the method described in Example 3 of the patent CN10148518A; the sample of the test example was prepared according to the method described in Example 2.

[0063] Test method: Weigh (400±0.5) g of filtered (177 μm pore size, 80-mesh filter) emulsion into a suitable container (about 100 mm in diameter and about 180 mm in height) of about 500 mL, and place it on a high-speed dispersing machine base On, fix with clips, start the dispersant (the stirring head is toothed disc type, about 40mm in diameter), adjust the speed at 2500r / min, disperse for 0.5h, then filter, and wash the residue on the inner wall of the container into the filter with tap water , Rinse the filter screen with tap water, dry all the precipitates, calculate the mass percentage of the precipitates, and measure the above experiment 3 times in parallel; observe whether the emulsion break...

Abstract

The invention relates to the field of high polymer materials, in particular to an ammonia-containing hydroxyl siloxane polymer and a preparation method thereof. The ammonia-containing hydroxyl siloxane polymer is specifically a polymer as shown in a formula (I) which is shown in the description. The polymer has good hydrophily, good wear resistance and good air permeability and is suitable for being used as a softener in leather industry or as a blending and softening agent in textile industry.

Description

technical field [0001] The invention belongs to the technical field of polymer compounds. It specifically relates to the preparation and application of a polymer containing organosiloxane in the field of leather or textile light industry. Background technique [0002] Textile products generally need to take necessary anti-corrosion, wear-resistant, and supple measures to improve the quality of the product. The use of softeners for protection is the simplest and most effective method. At present, when fabrics are protected and softened, an aqueous solution is usually used. In addition to the aqueous solution, polysiloxane is also added, and it is usually temporarily prepared into the form of an aqueous emulsion with the help of a suitable emulsifier. The application of polysiloxanes in aqueous solutions can cause various problems during industrial applications due to the high shear forces of jet dyeing machines which often delaminate the emulsion when used in jet dyeing mach...
