Silicon acrylic emulsion printing adhesive

Abstract

The invention discloses a silicon acrylic emulsion printing adhesive, relating to the technical field of chemical engineering. The silicon acrylic emulsion printing adhesive is prepared by the following steps: (1) firstly, feeding purified water, tert-butyl alcohol and methanol into a reaction kettle for evenly stirring and mixing, heating to 50-60 DEG C to obtain a solution a for later use; (2) dissolving nano titanium dioxide, butyl acrylate, plant fibers, acrylic acid and anionic ring-opening polymerization emulsion into the solution a, fully stirring evenly, heating while stirring until the temperature achieves 80-90DEG C, and preserving heat for 2 hours to obtain a solution b for later use; (3) adding hydrogen silicon oil, an emulsifying agent and ethylene silicon oil into the solution b, and evenly stirring for 30minutes at the stirring speed being 3500r / min to obtain a solution c for later use; (4) controlling the temperature of the solution c to be 40-45DEG C, then dropwise adding dimethylformamide within 0.5 hour, and cooling to room temperature to obtain the solution d for later use; and (5) regulating the pH value of the solution d to be neutral through ammonium water, and discharging to obtain an adhesive. The silicon acrylic emulsion printing adhesive has multiple advantages of no environmental pollution, no hazard, complete chromatography, easy color matching, fresh color and the like, and can be widely applied in the printing and dyeing industry.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a silicone acrylic emulsion printing adhesive. Background technique [0002] The pigment printing process has the advantages of simplicity, short production process, energy saving and water saving, complete color spectrum, bright colors, clear pattern outline and distinct layers, and is suitable for various fibers and blended fabrics. In pigment printing, insoluble pigments have no affinity for fibers, and this printing method requires a binder to fix the paint on the textile. Acrylic adhesives are often used as adhesives for pigment printing. Acrylic polymers contain functional groups such as carboxyl groups and ester groups, have strong polarity, and have strong adhesion to pigments and fibers; good transparency, weather resistance, anti-oxidation and UV resistance; acid and alkali resistance, stability and oil resistance Good, with high breaking strength and elonga...

Problems solved by technology

However, there are disadvantages such as poor water resistance, brittleness at low temperature and stickiness at high temperature, etc., so that the printing process has always had problems such as unsatisfactory rubbing fastness of printed fabrics, hard hand feeling and poor breathability and comfort of the film.
