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 monomer and 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 coatings and coating dyeing, and in particular to a preparation method and use of a cationic adhesive. Background technique [0002] Paint dyeing is one of the water-less and water-less dyeing and finishing technologies advocated for many years. However, the conventional dyeing technology currently used simply uses anionic binders as the medium to dye fabrics with paint, which suffers from poor dyeing depth and color fastness. Obvious defects such as low strength, hard feel and sticky rollers have restricted the popularization and application of paint dyeing. [0003] From the perspective of the coating dyeing mechanism, the coating has no affinity for the fiber. The dyeing of the fiber by the coating is to adhere the coating to the fiber through the action of an adhesive. Conventional adhesives are negative. Since most fibers are negatively charged in the dye bath, the paint is also negatively charged. Due to electrostatic r...
