The Chinese invention patent application with the publication number CN 101497967A discloses a method for preparing a fabric softening and finishing agent block water-soluble silicone oil. 1. The preparation of polyorganosiloxane-polyether linear block copolymer and the ammonolysis of block copolymer four preparation steps improve the contradiction between the hand feeling and hydrophilicity of ordinary hydrophilic polyether modified amino silicone oil , but the preparation process is complicated and the cost is high
Such products are represented by special silicone oils such as Magnasoft SRS, Magnasoft JSS and Magnasoft SILQ of Momentive Corporation of the United States. Several domestic companies and research institutions are developing such products. The cost of this type of hydrophilic silicone softener is very high. The price of general amino silicone oil is several times higher, so it is not suitable for application in general products, and as far as the current Momentive products are concerned, the application is selective for fabrics. For example, Magnasoft SRS is especially suitable for soft finishing of polyester and wool products, with excellent hand feeling. , less hydrophilic

Abstract

The invention discloses aminosilicone durable hydrophilic potentiating agent, and a preparation method and the application thereof. The preparation method is that methyl silicone oil containing hydrogen, allyl-terminated epoxy-terminated compound and allyl polyether are reacted under the effect of platinum catalyst in oxygen-free condition, so that the aminosilicone durable hydrophilic potentiating agent is obtained. The method has the advantages that the reaction step is simple, the reaction condition is mild, and the method is simple and easy. The aminosilicone durable hydrophilic potentiating agent not only can be independently used before and after the softening finish of traditional aminosilicone, but also can be co-bathed with traditional aminosilicone emulsion; as the agent has good penetrability, wettability and reactivity, the agent can not only keep the soft and smooth feel of the traditional aminosilicone, but also give good hydrophilicity to fabrics in the condition that the use level is low, and also has durability; and the difference between the fabric finished by the aminosilicone durable hydrophilic potentiating agent and the fabric finished by the independently used traditional traditional aminosilicone emulsion is that fabric treated by the aminosilicone durable hydrophilic potentiating agent can be directly repaired without treatment.

Description

technical field [0001] The invention belongs to the technical field of textile chemical industry, and in particular relates to an amino silicone oil (emulsion) durable hydrophilic synergist and its preparation method and application. Background technique [0002] Amino-modified silicone oil has been produced and applied in my country for more than 20 years. At present, it is still a dominant variety in softening finishing auxiliaries. Amino silicone oil can be widely used in the soft finishing of various natural fibers and synthetic fibers. The fabrics treated with it have the advantages of softness, smoothness, plumpness and washability. Traditional amino silicone oils can give fabrics a good feel, but there are also Congenital deficiency, in addition to the ordinary amino silicone oil emulsion will cause demulsification and oil floating due to factors such as alkali on the cloth surface or long-term shearing during use, the fabric after ordinary amino silicone oil emulsion...
