Abstract
A disclosed preparation method for a nanometer titanium dioxide finishing agent comprises the following steps: (1) mixing water and concentrated hydrochloric acid to prepare a hydrochloric acid aqueous solution; (2) uniformly mixing tetrabutyltitanate and glacial acetic acid, dropwise adding into the hydrochloric acid aqueous solution, continuously stirring for 5-6 h for a reaction; (3) dissolving an adhesive in water to prepare an adhesive aqueous solution with a mass percent of 1%; and (4) adding the solution obtained in the step (2) into the adhesive aqueous solution, and then dispersing for 20-30 min in the presence of ultrasonic to obtain the nanometer titanium dioxide finishing agent. The preparation method for the finishing agent is simple in operation and low in cost, and fabrics finished by using the prepared finishing agent has good ultraviolet resistant endurance and antibacterial property.
Description
Technical field:
The present invention relates to fabric finishing agent technical field, relate in particular to a kind of preparation method of nanometer titanium dioxide finishing agent.
Background technology:
Along with the progress of science and technology and the raising of living standards of the people, people propose more, higher requirement to textile product, the uvioresistant energy of such as clothes and antibiotic property etc.Nano titanium oxide has the features such as nontoxic, tasteless, active high, Heat stability is good, not easily decomposition, the uvioresistant of textiles excellence, the function such as antibacterial can be given, but directly using nano particle to exist easily reunites, the problem of difficulties in dispersion, and there is shortcomings such as arranging rear fabric feeling, drape style, moisture permeability variation, have impact on the extensive use of nano material.Take nanometer technology as the nano functional finishing agent that core is developed, not only efficient but also environmental protection, undoubtedly for the finishing functions of textiles brings revolutionary change.
Summary of the invention:
The object of this invention is to provide a kind of preparation method of nanometer titanium dioxide finishing agent, this preparation method is simple to operation, can significantly improve anti-ultraviolet property and the antibiotic property of fabric after prepared finishing agent finish fabric.
Object of the present invention is achieved through the following technical solutions:
A preparation method for nanometer titanium dioxide finishing agent, comprises the following steps:
(1) mixed in hydrochloric acid being 36% by the concentration of the water of 7.5-8.5 weight portion and 0.0025-0.003 weight portion evenly obtains aqueous hydrochloric acid solution;
(2) at 20-30 DEG C, after the glacial acetic acid of the tetrabutyl titanate of 1 weight portion and 0.6-0.8 weight portion is mixed, be slowly added dropwise in above-mentioned aqueous hydrochloric acid solution, continuous stirring reaction 5-6h;
(3) adhesive of 0.1 weight portion is dissolved in the water of 9.9 weight portions and obtains the binder aqueous solution that mass fraction is 1%;
(4) gained solution in step (2) being added weight fraction is in the binder solution of 1%, then at ultrasonic lower dispersion 20-30min, obtains described nanometer titanium dioxide finishing agent.
Preferred as technique scheme, described adhesive is polyacrylate dispersion, one or more combination in polymethylacrylic acid emulsion, acrylamide and acrylate copolymer emulsion or acrylate and acrylonitrile compolymer emulsion.
Beneficial effect of the present invention is: finishing agent preparation method provided by the invention, simple to operate, with low cost, and the fabric using the finishing agent of preparation to arrange has good uvioresistant durability and antibiotic property.
