Problems solved by technology

However, amino silicone oil cannot be used directly, it must be emulsified with an emulsifier before use
During the use of amino silicone oil, there are problems such as easy demulsification, floating oil, sticking to rollers, sticking cylinders, and easy to produce silicone oil spots. A series of problems such as the fabric cannot be repaired
[0003] In recent years, block silicone oil, which replaces amino silicone oil products, has gradually become popular in the market. However, due to the complicated s

Example Embodiment

[0021] Example one

[0022] A method for synthesizing low-solvent block silicone oil, including the following steps: Step 1. Add low-hydrogen-containing silicone oil and allyl epoxy polyether with a molar ratio of 1:2 to the reaction kettle, wherein the low-hydrogen silicone oil at the end is added The molecular weight is 4000, and the molecular weight of allyl epoxy polyether is 500-2000. Then add a certain amount of isopropanol to the reactor, heat the reactor to 70°C, stir evenly, add a certain amount of chloroplatinic acid, keep the temperature for 4 hours, and then lower the temperature to below 40°C and discharge to obtain the intermediate Step 2: Put the intermediate and diethylenetriamine with a molar ratio of 1:1 into the reaction kettle, keep the reaction at 80°C for 12 hours, and cool to below 40°C to obtain low-solvent block silicone oil. In step 1, the weight ratio of isopropanol to all the materials in the reactor is 5:100, and the weight ratio of chloroplatinic ac...

Abstract

The invention discloses a synthetic method of a low-solvent block silicone oil. An intermediate is obtained through reaction of end low hydrogen containing silicone oil and allylic epoxy polyether. The low-solvent block silicone oil prepared by the preparation method is stable in quality and the fabric hand feeling finishing agent is prepared by the low-solvent block silicone oil, aiming at different fabrics and the pursuit of the styles of customers, the molecular weight can be changed and the amine in the amination process can be changed; and the end low hydrogen containing silicone oil andthe allylic epoxy polyether of the block silicon oil are low in molecular weight and the polymorphism of the amine in the amination process greatly improve the flexibility of the block silicone oil, and the effects of different styles can be finished for different fabrics or the same fabric, and a corresponding hand feeling style can be effectively sorted out according to customer requirements.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a method for synthesizing low-solvent block silicone oil and a hand finishing agent containing the low-solvent block silicone oil. Background technique [0002] At present, more than 80% of the hand finishing agents for textiles on the market need to use amino silicone oil. The molecular main chain of amino silicone oil is composed of Si-O bonds with excellent flexibility, and amino groups of different structures are introduced into the side chains according to different aminosilane coupling agents. The amino groups have strong polarity, reactivity, and adsorption. Chemical properties such as resistance, thus endowing amino silicone oil with innate advantages in the effect of fabric hand finishing. However, amino silicone oil cannot be used directly, and must be emulsified with an emulsifier before use. During the use of amino silicone oil, there are problems such as ...
