Problems solved by technology

In the patent CN1583811, cationic monomers are used to prepare water-soluble cationic polymer powder products, which are used as clay stabilizers, paper-making strengthening agents, etc., but are hardly used in paint dyeing, and the paint dyeing adhesives reported in a large number of literature and patents (such as patent CN101020805) are all anionic, and the research of introducing cationic group is then relatively few

Abstract

The invention relates to cation adhesive emulsion, a method for making the same and a use of the same. The adhesive emulsion is generated through the reaction of the following compositions: soft monomer, hard monomer, crosslinking monomer, compound emulsifier of cation and nonionic emulsifier and initiator. When made, a mixed body of the soft monomer, the hard monomer and the crosslinking monomerand an initiator aqueous solution are added in the emulsifier and distilled water to carry out reaction; and the cation adhesive emulsion is made after cooling down and filtration. The aqueous latex not only has a simple making method, but also can be used in textile fabric coating dyeing, textile fabric function finish or the gluing fixative during nano material afterfinish; moreover, the aqueous latex can be used as the film former of an aqueous coating material.

Description

technical field [0001] The invention relates to paint and paint dyeing, in particular to a preparation method and application of a cationic adhesive. Background technique [0002] Pigment dyeing is one of the anhydrous and less water dyeing and finishing technologies advocated for many years, but the conventional dyeing technology currently used only uses anionic binder as the medium to realize the dyeing of paint on fabrics, which has poor dyeing depth and color fastness. Obvious defects such as low density, hard hand feeling and sticky roller restrict the popularization and application of paint dyeing. From the perspective of paint dyeing mechanism, paint has no affinity to fibers, and the dyeing of paint to fibers is to fix the paint to fibers through the action of adhesives. Conventional adhesives are negative loading. Since most fibers are negatively charged in the dyeing bath, the paint is also negatively charged. Due to electrostatic repulsion, the combination of th...
