[0005] Chinese patent CN98100930.1 (1998.03.19) discloses a kind of butadiene as the main monomer, adopts microemulsion copolymerization method to prepare adhesive, its particle size is 40-50nm, it is mainly used in traditional paint textile printing , no application in inkjet printing
U.S. Patent USP6117939 (2000.09.12) and USP6365675 (2002.04.02) adopt low-shear emulsification and add co-surfactant to prepare thermoplastic acrylate microemulsion, but the solid content of preparation is low, can not form self-crosslinking coating film, also No application in inkjet printing
Chinese patent CN03113855.1 (2003.03.06) discloses high solid content acrylate microemulsion and its preparation method and application, the average particle diameter of its microemulsion is less than 100nm, but the weight ratio of soft monomer and hard monomer in microemulsion Less than 1, the film formation is relatively hard, and the application field is wood coatings
However, its high polymer is a structural high polymer, such as block polymer, graft polymer or branch polymer, and the preparation process is loaded down with trivial details. If the ratio is less than 1, the polymer is only used as a dispersant for pigment particles. When it is applied to inkjet printing, the fabric needs to be pretreated with a crosslinking agent first, and then printed after drying, which is a complicated process.

Abstract

The disclosed preparation method for nano-polymer microemulsion in ink-jet printing comprises: using soft monomer butyl acrylate as main polymonomer for well film-forming flexible; adding comonomer with cross-linkging group to form three-dimensional space network structure and fix the color particle hard on textile fabric to prevent film tacky and endow the fabric with well resistance ability; adding polymerisable surfactant to let the polymer microemulsion have super stability even with much soft monomer and average size less than 100nm hard to agglomeration. This invention can obtain the product with small size and narrow distribution.

Description

technical field [0001] The invention relates to an adhesive for textile printing, in particular to a nanoscale polymer microemulsion for textile inkjet printing and a preparation method thereof. Background technique [0002] Inkjet printing technology is a brand-new textile printing technology. It sprays the ink containing pigment (dye or pigment) onto the substrate to be printed through the nozzle of the inkjet printing machine, and is controlled by the computer to form a pattern according to the design requirements. According to the performance of the ink, the printed fabric with certain fastness and vividness can be obtained through proper post-processing. Compared with traditional printing methods, inkjet printing has many advantages such as printing high-precision personalized patterns, meeting the production requirements of small batches and multiple varieties of textiles, quick response, saving time and space, and environmental protection. [0003] One of the core te...
