Description

Technical Field

[0001] This technical solution mainly involves the "field of organosilicon chemistry", "field of emulsion preparation technology" and "field of polymer materials", and specifically involves an organosilicon emulsion, a preparation method and an application. Background Art

[0002] Silicone is an important chemical raw material, widely used in various industries, such as construction, automobiles, electronics, textiles, etc. Among them, silicone emulsion is an important silicone product, which has good stability, weather resistance, lubricity and water resistance. However, the preparation process of silicone emulsion is complicated, and the proportion of various raw materials and reaction conditions need to be precisely controlled to ensure the quality and performance of the product.

[0003] Amino silicone oil of organic silicon is usually used in hair care products to improve the softness and combing properties of hair. Its advantage is that it contains hydrophilic groups and is easy to emulsify into emulsion and add to water-based hair care products. The method of mercapto modification is usually used in silicone rubber to improve the toughness of silicone rubber, and is also used in the textile industry to treat the surface of fabrics. Mercapto and amino co-modified silicone oil can take advantage of the advantages of the two groups to adjust the smoothness and toughness of hair.

[0004] Although the existing technology for preparing silicone emulsions has made some progress, there are still some problems and shortcomings. First, the types and proportions of raw materials in the existing technology are relatively fixed and difficult to adjust according to actual needs, which limits the performance and application range of the emulsion. Secondly, the reaction conditions in the existing technology are relatively harsh, such as high temperature, high pressure and long reaction time, which not only increases the production cost, but also increases the safety risk of production.

[0005] In addition, the existing technology for preparing mercapto and amino co-modified silicone oil emulsions often adopts a direct emulsification method. This method has low efficiency in obtaining the emulsion, and the emulsifier used is generally a non-silicone emulsifier with weak emulsification performance. In addition, the internal phase silicone oil is usually end-capped and cannot form a cross-linked network structure, resulting in poor film-forming effect. It has not yet been applied to the field of hair care.

[0006] In view of this, the present invention provides an organosilicon emulsion, a preparation method and an application thereof. Summary of the invention

[0007] The purpose of the present invention is to provide a silicone emulsion, a preparation method and an application thereof in view of the deficiencies of the prior art.

[0008] In order to solve the above technical problems, the following technical solutions are adopted:

[0009] A silicone emulsion comprises amino- and mercapto-modified silicone, an emulsifier and water, wherein the amino- and mercapto-modified silicone is a type of modified silicone material with amino groups and mercapto groups introduced into the silicone molecular structure, and the emulsifier is a polyether-modified silicone emulsifier.

[0010] The present invention proposes another technical solution: a method for preparing an organosilicon emulsion, characterized in that: the reactants are prepared as follows:

[0011] Internal phase oil: polydimethylsiloxane monomer, aminosilane, mercaptosilane;

[0012] Emulsifier: polyether modified silicone emulsifier;

[0013] Catalyst: basic catalyst;

[0014] Terminator: organic acid;

[0015] The specific reaction steps are as follows:

[0016] S1. The polydimethylsiloxane monomer, polyether-modified silicone emulsifier and water are stirred at 800-1200 rpm for 20 min until completely uniform, and then circulated 2-5 times through a homogenizer at a pressure of 20-40 MPa;

[0017] S2. First add aminosilane and mercaptosilane, then add alkaline catalyst, heat to 80-85°C, and react for 10-20h;

[0018] S3. Add terminator to adjust pH to neutral, and the discharge reaction is completed.

[0019] A further improvement based on the technical solution is that the polydimethylsiloxane monomer is a mixture of one or more of D3, D4, D5 and linear silicone oil.

[0020] A further improvement based on the technical solution is that the aminosilane is one of γ-aminopropyltriethoxysilane, β-aminoethyl-γaminopropylmethyltrimethoxysilane, and 1,3-bisaminopropyltetramethyldisilane.

[0021] A further improvement based on the technical solution is that the mercaptosilane is one of 3-mercaptopropylmethyldimethoxysilane and 3-mercaptopropyltrimethoxysilane.

[0022] A further improvement based on the technical solution is that the polyether-modified silicone emulsifier is one or a mixture of PEG-3 polydimethylsiloxane, PEG-6 polydimethylsiloxane, PEG-8 polydimethylsiloxane, PEG-10 polydimethylsiloxane, and PEG-12 polydimethylsiloxane.

[0023] A further improvement based on the technical solution is that the alkaline catalyst is one of sodium hydroxide, potassium hydroxide and tetramethylammonium hydroxide.

[0024] A further improvement based on the technical solution is that the organic acid is one of glacial acetic acid, tartaric acid, lactic acid and citric acid.

[0025] A further improvement based on the technical solution is that the content of the polydimethylsiloxane monomer is 25%-40%, the content of the aminosilane is 2%-10%, the content of the mercaptosilane is 0.5%-5%, the content of the polyether modified silicone emulsifier is 2%-10%, the content of the alkaline catalyst is 0.01%-1%, the content of the organic acid is 0.01%-1%, and the rest is water.

[0026] The present invention proposes another technical solution: the organosilicon emulsion is applied to hair care products to improve combing performance, enhance hair strength, enhance heat conduction efficiency on the hair surface, and reduce hair damage.

[0027] Or the organosilicon emulsion is used in color protection products to reduce color fading and maintain color brightness.

[0028] The above technical solution has the following beneficial effects:

[0029] This organosilicon emulsion connects amino and thiol groups to an uncapped organosilicon structure by emulsion polymerization. When used in hair care products, it has certain film-forming properties and thus a certain waterproof effect. At the same time, the modified thiol structure can combine with the broken disulfide bonds on the surface of damaged hair. In this way, through the molecular force between the organosilicon structure and the hair surface, plus the ionic bond force between the amino group and the hair surface and the covalent bond force between the thiol group and the hair surface, its film-forming properties are more stable and can cover the hair surface more efficiently. In addition, the emulsion prepared by emulsion polymerization of organosilicon polyether modified emulsifier has better stability, high production efficiency, no waste, and is more suitable for mass production. The specific beneficial effects are as follows:

[0030] 1. Strong flexibility: The types and proportions of raw materials of the present invention can be adjusted according to actual needs, rather than just a few fixed ones, so that silicone emulsions with different properties and application ranges can be prepared, thereby enhancing the flexibility and adaptability of the product.

[0031] 2. Optimization of reaction conditions: The reaction conditions of the present invention are relatively mild. Although high temperature and high pressure are still required, the reaction time is short, which reduces production costs and improves production safety. At the same time, such reaction conditions are also easier to control, which is conducive to improving the stability and service life of the product.

[0032] 3. Accurately control pH: The present invention adopts a special pH adjustment method, which can more accurately control the pH value of the emulsion to make it neutral, thereby ensuring the stability and service life of the emulsion, avoiding the problems caused by inaccurate pH adjustment in the prior art.

[0033] In general, compared with the prior art, the present invention has higher flexibility, better reaction conditions and more precise pH control, which make the present invention have greater advantages and better application prospects in the preparation process of silicone emulsion.

[0098]

[0099]

[0100] The laboratory tests are as follows:

[0101] (1) Combing performance test

[0102] Take 4g of damaged real hair, wash it with 10% sodium lauryl ether sulfate for 3 times, place it in a constant temperature and humidity chamber for 24h, test the combing work with a hair combing tester (Dia-stron), test it 10 times, take the average value, and get the combing work W1. Then, take 3g of conditioner and apply it evenly on the test hair, rinse it with clean water 3 times, place it in a constant temperature and humidity chamber for 24h, test the combing work, test it 10 times, take the average value, and get the combing work W2. Calculate the reduction in combing work W%: W = (W1-W2) / W1.

[0104] After rinsing with clean water three times, place it in a constant temperature and humidity chamber for 24 hours, and test the reduction in combing work again. Repeat the above operation 5 times and record the reduction in combing work. The results are as follows.

[0105] (2) Hair strength test

[0106] Take a healthy human hair bundle and divide it into 2 parts, each part is about 4g, one part is washed 3 times with 10% sodium lauryl ether sulfate, and the other part is washed 3 times with conditioner. Both parts are blow-dried with a hair dryer and placed in a constant temperature and humidity chamber for 24 hours. The tensile force of the hair at break is measured by a texture analyzer (TA-X20) and recorded as F1. Then, the hair is ironed 10 times with a curling iron. After returning to room temperature, the tensile force of the hair at break is measured by a texture analyzer (TA-X20) and recorded as F2. The difference in tensile force ΔF is calculated to determine the degree of damage to the hair after ironing. The larger the difference, the more serious the degree of damage. The results are shown in Table 3.

[0109]

[0110] (3) Color protection performance test

[0111] A healthy human hair bundle was taken and divided into two parts, each weighing about 4 g. After being dyed evenly with a commercially available red hair dye, one part was washed three times with 10% sodium lauryl ether sulfate, and one part was washed three times with a conditioner. Both parts were blow-dried with a hair dryer and placed in a constant temperature and humidity chamber for 24 hours. The color difference ΔE of the hair before and after washing was measured with a colorimeter. The smaller the difference, the better the color protection effect. The results are shown in Table 4.

[0115] 20 volunteers were selected and divided into 5 groups. The same hair dye was used for hair perming and dyeing experiments. The above hair conditioner was used for one week before perming and after dyeing (each group corresponds to an embodiment / control example). After perming and dyeing, the smoothness and health of the hair were evaluated and scored. The evaluation results are shown in the following table
