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
The invention belongs to technical field of textile chemical engineering, be specifically related to hydrophilic synergist of a kind of amido silicon oil (emulsion) durability and preparation method thereof and application.
Background technology
Amino-modified silicone oil in soft after-treating auxiliary, remains a kind of occupying leading position at present in the history in existing more than 20 year of China's production application.Amido silicon oil can be widely used in the soft finish of various natural fabrics and synthetic fiber; Have softness, advantage such as smooth, plentiful and washable through the fabric of its arrangement, traditional amido silicon oil can give fabric good feel, but also exists inborn deficiency; Except in use; Common amino silicon oil emulsion is because cloth is worn the influence of factors such as alkali or long-time shearings can occur outside breakdown of emulsion and the floating oil phenomenon, and the fabric after the common amino silicon oil emulsion of process is put in order can be hydrophobicity and makes the snugness of fit variation; And cause returning something for repairs at lining, bad when redying owing to infiltration, absorb the inhomogeneous serious look flower that occurs; Therefore can't directly return something for repairs, must use special silicone oil stripper could amido silicon oil thoroughly be divested, just can redye then.Amido silicon oil is because hydrophilicity is poor in addition, and the fabric antistatic property after its arrangement is also poor, is easy to generate the caused variety of issue of static.Therefore, the hydrophilic modifying of common amido silicon oil becomes a focus of present silicone softening agent research, present stage the hydrophilic organic silicone softener mainly contain three types, be respectively the amino block silicone oil of polyether modified silicon oil, hydrophilic polyether modified amino silicon oil and linear polyether.
The representative products of polyether modified silicon oil is the CGF of former Chenguang Chemical Inst., Ministry of Chemical Industry research and development, is characterized in good hydrophilic property, and feel is general, and washability is relatively poor.The hydrophilic polyether modified amino silicon oil is to introduce amino and hydrophilic polyether segment simultaneously at the polysiloxane molecule side chain; So just can be under the prerequisite that to a certain degree keeps the amido silicon oil feel; Improve the hydrophily of fabric, solved traditional amido silicon oil exist can not return something for repairs after dying, snugness of fit difference and difficult problem of cleaning.The maximum problem of hydrophilic polyether modified amino silicon oil is after hydrophily is better improved; Feel is often comfortable not as the amino-modified silicone oil softness; Vice versa; Be the relation of contradiction between the two, there is hydrophilic unabiding problem in this type of silicone oil like the DC8600 of Dow Corning Corporation and the TEX180 of GE Toshiba in addition.Publication number is that the Chinese invention patent of CN 1919896A discloses a kind of method for preparing hydrophilic silicon oil; This method adopts silicon oil of low hydrogen content and polyethers under the effect of chain-transferring agent and catalyst, to react; Introduce amino coupling agent; Prepare amino modified hydrophilic silicon oil at last, this method has been improved the hydrophily of amido organosilicon softener, but the feel of the fabric of handling is declined to a great extent.And the amino block silicone oil of linear polyether is owing to be that straight-chain polyether amino is block modified; It pushes the hydrophilic organic silicon fabric finishing agent on the step of a renewal; Well balance feel and hydrophilic contradiction; Product each item has good stability, and is very outstanding at aspects such as high temperature resistant, anti-high shear, electrolyte-resistant and strong acid-base resistances, almost is fit to all back finishing process.Publication number is the preparation method that the Chinese invention patent application of CN 101497967A discloses a kind of fabric softener block water-soluble silicon oil; This method adopts the amidatioon of amino coupling agent, preparation, the polysiloxane-preparation of polyethers linear block copolymers and the ammonia of block copolymer of the hydrogeneous methylsiloxane intermediate of end to separate four preparation processes; The feel of common hydrophilic polyether modified amino silicon oil and the contradiction between the hydrophily have been improved; But complicated process of preparation, cost are very high.This series products is with the Magnasoft SRS of U.S. Mai Tu company, and extraordinary silicone oil such as Magnasoft JSS and MagnasoftSILQ are representative, and domestic existing several companies and research institution are at this series products of exploitation; The cost of this type of hydrophilic organic silicone softener is very high; Be the several times of general amido silicon oil price, inapplicablely in common product, use, and with regard to the product that steps figure at present; Selective during application to fabric; Such as the soft back arrangement that Magnasoft SRS is particularly suitable for washing the suede series products, feel is good, and is hydrophilic relatively poor.
The present development of tradition amido silicon oil is very ripe, and its style and feel are varied, comprises softness, smooth, fluffy and elasticity etc.; Its applicable scope has almost comprised all fabric types (cotton, hair, wash etc. and various BLENDED FABRIC); And it has very high cost performance, therefore, and in long period of time; The tradition amido silicon oil still can be a softener kind of occupying leading position; But people are increasingly high to the hydrophilic and snugness of fit requirement of fabric, under these circumstances, seek the problem that a kind of amido silicon oil synergist with good hydrophily and durability becomes needs solution.
