Abstract

The invention discloses a method for preparing an acrylate printing adhesive, which is prepared by the following steps: (1) weighing a common monomer, a special monomer, an emulsifier, an initiator and deionized water in a mixing ratio; (2) mixing 40 to 60 percent of deionized water weighed in the mixing ratio, 40 to 60 percent of emulsifier weighed in the mixing ratio and 40 to 60 percent of initiator weighed in the mixing ratio to prepare liquid I; (3) mixing the common monomer and the special monomer, which are weighed in the mixing ratio, with 60 to 40 percent of deionized water, 60 to 40 percent of emulsifier and 60 to 40 percent of initiator, stirring and emulsifying to prepared liquid II; (4) dripping the liquid II into the liquid I; (5) after the liquid II is dripped, stirring, keeping temperature for reaction and obtaining an initial product of the acrylate printing adhesive; and (6) dripping ammonia water into the initial product of the acrylate printing adhesive to regulating the pH value of the initial product of the acrylate printing adhesive to 6.5 to 7.5, and filtering to obtain the acrylate printing adhesive product. The adhesive prepared by the method has high performance, and the environmental-protection problem in the synthesis and use processes of the adhesive is solved.

Description

technical field [0001] The invention relates to the technical field of preparing printing adhesives, in particular to an environmentally friendly and ecological method for preparing acrylate printing adhesives. technical background [0002] Pigment printing is a method of using the adhesive to form a film on the surface of the fabric, adhering the paint without affinity and reactivity to the fabric, and then fixing the paint on the surface of the fabric after baking, endowing the fabric with various colors and Graphic printing process. Compared with the traditional printing process, pigment printing has many advantages. For example, pigment printing is not limited by fabric fibers, nor is it affected by weaving methods; The technological process saves water, electricity and gas, and reduces the pollution of printing and dyeing wastewater to the environment; therefore, this process is widely used in the printing and dyeing industry. According to incomplete statistics, pigme...
