Abstract

The invention discloses a polyether modified polyacrylate ink-absorbing and fast-drying coating agent, a preparation method and application thereof. The preparation method comprises the following steps of enabling methyl methacrylate, butyl acrylate, acrylic acid and propenol polyether to react, so as to obtain a propenol polyether modified monomer mixed solution; using lauryl sodium sulfate and AEO-4 as emulsifiers, using sodium bicarbonate as a buffer agent, using polyvinyl alcohol as a stabilizing agent, using persulfate as a catalyst, and adopting an emulsion polymerizing method, so as to obtain the polyether modified polyacrylate ink-absorbing and fast-drying coating agent containing one polyether chain. The prepared polyether modified polyacrylate ink-absorbing and fast-drying coating agent has the advantages that the absorbing property of the coating agent film on water-soluble ink is improved by the polyether chain in the coating agent molecules, and the easiness in foaming of the coating agent is avoided by the polypropylene oxide chain; the active function groups in the coating agent can generate crosslinking function in the fabric arrangement process, so that the adhesion force of the coating agent onto textile is improved; the obtaining of raw materials is easy, the technology is simpler, the reaction control is easily controlled, and the obtained coating agent has better ink-absorbing and fast-drying properties.

Description

Technical field [0001] The invention relates to a polyether modified polyacrylate, a preparation method and application thereof, in particular to a polyether modified polyacrylate ink-absorbing quick-drying coating agent for textiles and a synthesis method thereof. Background technique [0002] The current inkjet printing technology of textiles is developing rapidly, especially in outdoor advertising, inkjet printing, exhibition wall textiles and other applications. However, the inkjet printing of textiles has disadvantages such as less ink absorption, longer surface drying time, and poor image clarity. However, coating a layer of ink-absorbing coating agent on the textile surface can better improve the ink absorption of textiles. Dry performance promotes the rapid development of inkjet printing technology in the textile field. [0003] At present, the application of ink-absorbing coating agents in the fields of paper printing and inkjet is relatively mature, and there are many re...
