Problems solved by technology

Although these modification methods can inhibit yellowing or non-yellowing to a certain extent, the price of the exchange is that the original soft and smooth style of amino silicone oil will inevitably be reduced.
At the same time, due to the influence of the reaction depth of the modifying reagent and the active hydrogen in the aminosilane and the degree of activity of the modifying reagent, the modification is often very unbalanced and difficult to control.
As a result, the modified product has poor stability and a flat feel
Moreover, toluene and organic alcohols are used in most modification methods, which have caused a considerable degree of negative impact on the health of production operators and the atmospheric environment

Abstract

The invention discloses a method for preparing branched-chain amino long-chain alkyl co-modified silicone oil, and microemulsion liquid thereof as well as an application thereof. The constitutional formula of the silicone oil is shown on the right. Hindered amino-silane, secondary amidocyanogen silane and alkyl silane (which are not easy to change color and denaturize under high temperature) as well as linear body are chosen in the method for reaction through polymerization balance, and the desired amino-modified silicone oil is synthesized. When the microemulsion softening agent emulsified by the product is used to neaten textile fabrics, high softness and smooth texture can be achieved. In addition, the product has sound stability to shearing force, centrifugal force as well as electrolyte, hard water, and the like, and the product does not has any adverse effect on the color light of textile fabrics, and yellow stain can be avoided. The product is applicable to white and light-colored textile fabrics neatening, particularly applicable to easy-care neatening of mercerized wool textile fabrics and white and light-colored textile fabrics, the processed textile fabrics have the advantages of soft, smooth and plumpy texture, and the original color tone and style can be maintained.

Description

technical field [0001] The invention relates to a silicone polymer, in particular to a branched-chain amino long-chain alkyl co-modified silicone oil and its application. Background technique [0002] Amino-modified silicone oil is widely used in textile printing and dyeing, leather, papermaking, and daily necessities care due to its excellent and outstanding soft and smooth feel. However, because the contained amino groups, especially the primary amino groups, are easily oxidized, the white and light-colored fabrics after finishing are yellowed, which affects the finishing effect of the fabric and the aesthetics of clothing. There are many ways to modify amino groups to inhibit or reduce yellowing. Such as modification with epoxy group, co-modification with epoxy group and acrylate (JP-6-184946.1994, JP-4-119174.1992); modification with polyoxyalkylene glycidyl ether (JP-9-21071.1997); Modification with polyether isocyanate and epoxy (JP-P-4-11081.1992); modification with...
