3-[DIMETHOXY(METHYL)SILYL]PROPYL GLYCIDYL ETHER - Reference Information
| LogP | 1.7 at 20℃ |
| application field | 3-(2, 3-epoxypropoxy) propylmethyldimethoxysilane beneficial effect: 1) the invention provides a preparation method of an epoxy-based organic fluorine silicone oil emulsion deepening finishing agent by reacting octamethylcyclotetrasiloxane, trifluoropropylmethylcyclotrisiloxane and a hydrolysate of an epoxy silane coupling agent under the action of a strong base catalyst, the epoxy-based organic fluorine silicone oil emulsion deepening finishing agent is obtained. The deepening finishing agent is applied to the fabric after finishing, so that the fabric has a soft and smooth hand, and the side chain contains fluorine atoms, after baking at high temperature, the film is formed, and fluorine atoms are easily enriched on the surface of the film, so that the refractive index of the fiber surface is greatly reduced, the amount of reflected light on the fiber surface is reduced, and the deepening effect is obvious. 2) The invention prepares a fabric darkening agent, which contains epoxy groups, so that when the post-finishing is baked at high temperature, the epoxy group reacts with the hydroxyl group on the surface to form a stable covalent bond, thereby increasing the adhesion to the fiber and improving the color fastness and washing resistance of the colored fabric. |
| Application | 1. 3-(2, 3-epoxypropoxy) propylmethyldimethoxysilane is an epoxy-based organofluorosilicone oil emulsion deepening finishing agent: Raw material composition and weight percentage content of the deepening finishing agent: octamethylcyclotetrasiloxane 5-35%, trifluoropropyl methyl cyclotrisiloxane 0.5 ~ 10% ,3-[(2,3)-glycidoxy] propylmethyldimethoxysilane 0.1~6%, capping agent 0.001 ~ 0.1%, strong alkaline catalyst 0.001 ~ 0.1%, emulsifier 0.1~2%, deionized water balance. 2. An antioxidant nylon material, prepared from the following parts by weight of raw materials: nylon resin 100-104 parts, glass fiber 10-20 parts, 3-[(2,3)-Glycidoxy] propylmethyldimethoxysilane 0.4-1.0 parts, dibutyltin maleate 0.2-0.6 parts, plasticizer 0.6-2.0 parts, antioxidant 0.6-2.5 parts. The anti-oxidation nylon material of the invention improves the mechanical properties and processing stability of the nylon material, and is convenient for industrial application. |
| Use | typical curing times are 16-20 hours at room temperature or 1 hour at 100 °c. |
