Modified polyether silicone oil
Modified polyether silicone oil has the unique advantages of excellent wettability, low surface tension and physiological inertness. It has been widely used in the fields of pulp and paper, agrochemicals, leather chemicals, especially fabric finishing and cosmetics. application.

1. Application in the textile industry
Fabrics finished with amino-modified polyether silicone oil (especially cotton fabrics) still retain good hydrophilicity and achieve high wrinkle resistance and super smooth feel. Adding it to the dyeing agent allows the reactive dye and the direct dye to not fade when the fabric is wet and dry. The treatment of the fabric or fiber with an amino group-modified polyether silicone oil containing an ester group allows the fiber fabric to be both ultra-soft and hydrophilic.
Polyether silicone oil containing arylamino group has higher heat resistance than ordinary polyether silicone oil, and is suitable as high temperature resistant fiber oil agent or resin additive. If it is added to ordinary polyether modified silicone oil, it can improve polyether. The heat resistance of silicone oil. The organosilicon copolymer containing epoxy group, amino group and polyether is easily soluble in water, can form a lake with water-soluble dye, can be enriched and formed on the surface of the fiber; has a sliding effect, can reduce the surface friction coefficient of the fiber It can significantly improve the dry and wet rubbing color fastness of the fabric; it can also make the dyed product after fixing has no color change problem, and still maintain the breathability of the fabric and the soft hand taking performance.
The fabric prepared by the amino group and the epoxy group co-modified polyether silicone oil has extremely low surface tension, and the contact angle with water is more than 150 ° C, showing superior hand feeling, and has good flexibility, fluffiness and slip. Sleek, can be repaired, not yellow. The carboxyl group-modified polyether silicone oil containing ester group has good dispersing effect on disperse blue dye, and can prevent dye re-aggregation when dyeing at high temperature; and phosphate ester modified polyether silicone oil has good lubricity and antistatic property to fiber. Sex.

2. Application in the daily chemical industry
The amino-modified polyether silicone oil is applied to the shampoo, which can not reduce foaming, reduce viscosity, and has a certain adsorption effect on the hair, and can make the hair fluffy, soft, smooth, antistatic and easy to comb. Amino-modified polyether silicone oil can be used in personal care products to produce skin-care products that are colorless, odorless, non-irritating to the human body, and do not affect the normal breathing and sweating of the skin. It also reduces the surface tension of cosmetics and is beneficial to cosmetics. It spreads on the skin and hair, imparts shine and antistatic properties to the hair, and has good inhibition to bacteria.
Adding amino-modified polyether silicone oil to the hair conditioner and hair styling formula not only has a shape-preserving effect, but also is easy to form a film, which makes the hair shiny and smooth, and can be used in the hair detergent formulation to make the hair Soft and shiny. Compared with the shampoo without silicone oil, the wet combing effect of the 2% quaternized polyether silicone oil can be increased by 28%, and the dry combing effect can be increased by 21.2%.

3. Application in papermaking and leather industry
When the amino-modified polyether silicone oil is added to the straw, the softness of the paper sheet can be increased by 48 mN with respect to the softness of the blank, and the softening effect is remarkable. The amino-modified polyether silicone oil is used for paper treatment, has a good softening effect, and has excellent wetting effect on paper fibers.
Leather slip agents containing polyether silicone oil, amino silicone oil and hydroxy silicone oil can meet the requirements of light, durability, smoothness, oiliness and waterproof. After the surface of the shoe is wiped with a shoe polish containing methyl silicone oil, polyether silicone oil or amino silicone oil, the brightness is very good; and after wiping the shoe polish, the brightness can be maintained for a long time to use the polyether modified silicone oil for the degreasing of the leather and Hair removal treatment can improve the quality of leather and reduce pollution.

4. Application in agriculture
Due to the low surface tension, the amino-modified polyether silicone oil can greatly reduce the surface tension of the pesticide, promote the rapid wetting of the pesticide emulsion, and penetrate into every small part of the leaves, stems and stems of the plant, so that the action of the pesticide can be maximized; And the action time is greatly extended. Vegetable and fruit residual pesticide cleaning agent containing polyether silicone oil and sucrose monolaurate, the surface pesticide residue removal rate is over 70%, the bacterial and parasitic egg removal rate is over 90%, and it is non-toxic and non-irritating to human body. High degradation rate.

5. Applications in other fields
Coating the fluorocarbon-modified polyether silicone oil on the inner surface of the phosphatized steel radiator, the coating can withstand the corrosion of alkaline water (pH 12 or higher) with high temperature of 140~C, adhesion and resistance The high temperature dynamic circuit water impact corrosion performance is excellent, can guarantee the service life of the steel radiator, and is non-toxic and odorless.
The silicone lubricant composed of amino polyether silicone oil or/and polyether silicone oil can effectively promote the lubricity and moisture absorption of the surface of the medical device and reduce the stimulation to the human body.
Polishing agents formulated with polyether silicone oils, amino silicone oils and nonionic surfactants are used in the polishing of vehicles such as automobiles to give vehicles a bright luster with long-lasting stain and water resistance.

6. Conclusion
As a non-toxic and non-polluting “green” product, modified polyether silicone oil is used more and more widely in various industries. With the deepening of research work, its application will be more extensive.
