Abstract
The invention discloses a method for preparing antibacterial polyurethane textile finishing liquid. The method comprises the steps of: firstly, adding an organic solvent N-methylpyrrolidone, MDI (4,4'-Methylenediphenyl Diisocyanate), HDI (Hexamethylene Diisocyanate) and a catalytic amount of dibutyltin dilaurate, and stirring and heating for dissolution; dropwise adding a mixed solution of polyether polyatomic alcohol N330, 1,4-butanediol and 1,3-dyhydroxy trimethylacetic acid, and reacting at 70-95 DEG C for 1-5h to obtain a prepolymerization product; then adding caprolactam, and reacting at 90-135 DEG C for 1-2h to obtain blocked polyurethane; then, adding aminoethyl imine propyl polysiloxane and an antibacterial agent nano zinc oxide, and polymerizing for 1-3h; and finally adding diethanol amine to obtain a product. The antibacterial polyurethane textile finishing liquid acquired according to the invention has the advantages of increased waterproofness, high antibacterial efficiency, high duration and capabilities of making fabrics with softness, crease resistance, washing fastness, wear resistance, good rebound resilience, freshness and good handfeel.
Description
Technical field:
The present invention relates to a kind of antibiotic property polyurethane textile dressing liquid, particularly the preparation method of antibiotic property polyurethane textile dressing liquid.
Background technology:
The enhancing of Along with people's growth in the living standard, the awareness of environment protection and health; Spin in clothes, family, travel, industry such as transportation; Requirement to the weaving special material is also increasingly high, requires lining to have certain softness, characteristic such as crease-resistant, and is also increasingly high to the quality requirements of softener.Amido silicon oil is widely used as the soft finishing agent of each kind fabric, gives good flexibility of fabric and smooth feeling.Polyurethane resin has adjustable, wear-resisting, the anti-solvent of soft durometer, low temperature resistant reaching with most of materials has than characteristics such as strong cementabilities, and development in recent years is rapid.Polyurethane successfully has been applied to textile printing and dyeing industry at present; It can give the good pliability of fabric, sense of fullness, washable, wear-resisting, resilience is good, smooth, good hand touch, antistatic etc., research and development in textile industry and application have obtained extensively and rapidly development.Yet, through the product of common fabric auxiliary agent arrangement, at a certain temperature and humidity conditions; Microorganism (bacterium and mould) will breed in a large number; Mould secretion causes the biodegradation of polyurethane, causes fiber surface to produce mildew and crackle, influences appearance of fabrics and service life; Therefore, extremely urgent to the research of functional antibiosis property finishing agent.
Summary of the invention:
Goal of the invention: the defective to prior art exists the invention provides a kind of antibiotic property polyurethane textile dressing liquid and preparation method thereof.
Technical scheme: for realizing the foregoing invention purpose; The present invention adopts following technical scheme: a kind of preparation method of antibiotic property polyurethane textile dressing liquid; May further comprise the steps: a, adding organic solvent N-Methyl pyrrolidone, 4 in being full of the agitated reactor of inert gas; The dibutyl tin laurate of 4 '-'-diphenylmethane diisocyanate MDI, hexamethylene diisocyanate HDI and catalytic amount stirs heating for dissolving down; B, in the solution that step a obtains, drip PPG N330,1,4-butanediol and 1, the mixed solution of 3-dihydroxy pivalic acid, 70 ~ 95 ℃ down reaction 1 ~ 5h obtain prepolymer product; C, continuation add the end-capping reagent caprolactam, and react 1 ~ 2h down at 90 ~ 135 ℃, obtain end-sealed type polyurethane; D, then add amido silicon oil aminoethyl imines propyl group polysiloxanes and antiseptic nano zine oxide, polymerisation 1 ~ 3h; E, add the diethanol amine neutralizer at last, the antibiotic property polyurethane products.
The mass ratio of said MDI and HDI is 1 ~ 5:1.
Said antiseptic nano zine oxide is of a size of 50 ~ 250nm.
According to above technical scheme; Can realize following beneficial effect: compared with prior art, the present invention has the following advantages: the present invention obtains antibiotic property polyurethane textile dressing liquid, and water proofing property improves; Antimicrobial efficiency is high; Longer duration makes fabric sofetening, crease-resistant, and is washable, wear-resisting, resilience is good, smooth, good hand touch.
The specific embodiment:
Below in conjunction with embodiment the present invention is done detailed description further, but the scope that the present invention requires to protect is not limited to the scope that embodiment representes.
