Problems solved by technology

[0007] Silicone-modified acrylate polymers have been used as an adhesive product with excellent performance. However, silicone-modified acrylate adhesives can solve the problem of the contradiction between the feel and fastness of adhesives. also has inherent flaws that are determined by its own consequences
High organic silicon content makes the fabric feel soft, but the fastness is reduced, especially the dry rubbing fastness is poor; low organic silicon content makes the fabric feel harder

Embodiment 1

[0072] In a four-neck flask with stirring, add 2.06 parts of dodecylbenzenesulfonic acid to 250 parts of water, heat to dissolve completely, then cool to room temperature, blow nitrogen for 15 minutes, and add octamethylbenzene under rapid stirring. 122.06 parts of cyclotetrasiloxane and 3.9 parts of vinyltriethoxysilane. After the addition, stir and emulsify quickly for 1 hour. After the emulsification is complete, slow down the stirring speed, start heating, heat to 85°C, keep warm for 3 hours, and then cool to room temperature, use 10% sodium carbonate solution to neutralize to about pH=7, and filter the material with 100-mesh nylon mesh to obtain low-molecular-weight silicone emulsion IA, with a pH value of 7.12, a gel rate of 2.07%, and a conversion rate of 96.42%. for:

Abstract

The invention belongs to the field of high polymer chemistry and pigment printing adhesion agents, and particularly relates to an organosilicone modification pigment printing adhesion agent and a preparation method thereof. The organosilicone modification pigment printing adhesion agent is obtained through copolymerization between low molecular weight organosilicone emulsion and an unsaturated monomer, and the structure of an organosilicone modification macromolecular compound is shown as a general formula (I). The pigment printing adhesion agent has the superior application performances of being soft in hand feel, high in all fastnesses, convenient to apply and the like. Particularly, the pigment printing adhesion agent not only can be used as printing on pure cotton fabric, but also can be used as printing on pure chemical fiber or blended fabrics.

Description

technical field [0001] The invention belongs to the field of macromolecule chemistry and pigment printing adhesive, in particular to an organosilicon modified pigment printing adhesive and a preparation method thereof. Background technique [0002] Pigment printing is a printing method that uses adhesives to adhere pigments to textiles, and is one of the most popular printing techniques at present. Printing paste is composed of colorants, adhesives, thickeners and a small amount of auxiliary materials. The quality of printing adhesives is the main factor restricting the development of pigment printing. Printing adhesives with excellent performance should comprehensively consider the three factors of printing fastness, fabric feel and whether the screen is blocked, especially the feel and fastness. At present, there are roughly three types of adhesives widely used, namely, acrylic esters, butadiene and polyurethanes. Among them, acrylate adhesive film has high transparency ...
