Abstract

The invention discloses a fluorine-silicon-modified acrylate adhesive which is prepared by the following raw materials by weight parts: 50 parts of water, 0.1-1 part of an anionic emulsifier, 10-20 parts of acrylate polymerizable monomers, 0.2-1 part of acrylic acid, 0.5-5 parts of fluorine containing organosilicon monomers, 0.1-2 parts of co-emulsifier and 0.1-1 part of an initiator. The fluorine-silicon-modified acrylate adhesive is a stable fluorine-silicon-modified acrylate emulsion, can be used for pigment printing, is soft in touch, high is color fastness, good in system stability and stable in product quality, and effectively solves problems of incompatible touch and fastness, and hot sticking and cold shortness existing in present acrylate adhesives. The invention further discloses a preparation method of the fluorine-silicon-modified acrylate adhesive. According to the method, stable fluorine-silicon-modified acrylate emulsion is prepared through miniemulsion polymerization. The method is simple in preparation, easy to implement and operate, and easy for industrial production, and has wide application prospect.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to an environment-friendly fluorosilicon-modified acrylate adhesive, a preparation method thereof, and an application as a pigment printing adhesive. Background technique [0002] Pigment printing is a method of mechanically fixing the paint that has no affinity and reactivity to fibers on the surface of the fabric with the help of adhesives. It only needs to fix the color and does not need to be washed. Therefore, it has the advantages of energy saving, water saving, and emission reduction, and is widely used by printing and dyeing enterprises. It is also listed by the National Economic and Trade Commission as one of the processes for promoting clean production in the textile industry. [0003] However, the handling properties such as feel and rubbing fastness of pigment printed fabrics largely depend on the performance of pigment printing adhesives. At present, the most widely used in ou...
