Embodiment 1

[0035] A. First, add 2 parts by weight of compound emulsifier and 20 parts by weight of deionized water into the polymerization reactor, stir and heat up;

[0036] B. 30 parts by weight of deionized water, 7 parts by weight of composite emulsifier, 25 parts by weight of hard monomer (8 parts by weight of styrene and 17 parts by weight of methyl methacrylate composite) are added in the pre-emulsification kettle, Under the condition of constant speed (820 rev / min), after stirring for 360 minutes, a pre-emulsion was obtained, and 4.96 parts by weight thereof were weighed as the bottom seed reaction solution for subsequent use;

[0037] C. Raise the temperature of the polymerization reactor in step A to 70°C, drop 4.96 parts by weight of the bottom seed reaction solution in step B, and then add 1 part by weight of the initiator as the bottom initiator to react for 90 minutes, and continue to the polymerization reactor Add 200 parts by weight of deionized water, slowly lower the te...

Abstract

The invention discloses a polyacrylate binder for pigment printing. The binder is prepared by polymerizing the following raw materials: a hard monomer, a soft monomer, a functional monomer, a compound emulsifying agent, organic silicone, an initiator, a pH regulating agent and deionized water. The invention also provides a preparation method of the polyacrylate binder for the pigment printing. According to the binder and the preparation method disclosed by the invention, proper proportion of the soft monomer to the hard monomer is selected, the mixture of a negative ion emulsifying agent and a nonionic emulsifying agent is used, and the binder is obtained through core-shell polymerization reaction so as to ensure that the binder for the pigment printing disclosed by the invention has pretty low film forming temperature, pretty good water resistance, and good scrubbing resistance, and can be widely applied to a pigment printing process in a dyeing and printing industry.

Description

technical field [0001] The invention belongs to the field of textile paints, in particular to a polyacrylate paint printing adhesive and a preparation method thereof. Background technique [0002] The pigment printing process not only has the characteristics of bright color, complete color spectrum, high color yield and easy color matching, but also has the advantages of simple process flow, energy saving and low cost, so it has developed rapidly in recent years and has become more and more popular. The printing and dyeing industry attaches great importance to it. The pigment printing process mainly uses the adhesive film-forming substance to fix the pigment that is insoluble in water, has no affinity and reactivity to the fabric on the fabric, so as to achieve the purpose of coloring, so the performance of the adhesive will directly affect the printed product. the quality of. [0003] However, this type of material still has some technical weaknesses in practical applicat...
