Abstract
The present invention relates to a preparation method of polyurethane anti-bacterial aromatic microcapsule. Its raw material includes oil phase and water phase, in which the oil phase is formed from polyisocyanate, essence, inorganic anti-bacterial agent and cyclohexane, and the water phase is composed of sodium hydroxide, sodium alginate and deionized water. Its preparation method includes the following several steps: adding polyethylene glycol and acetone into oil phase, mixing them and drop-adding the obtained mixture into water phase for 1.5-2hr, stirring speed is 400-600 rpm at 40-60deg.C, after the drop-addition is completed, heating to 50-70deg.C, making reaction for 1-1.5hr, filtering the obtained product so as to obtain the invented product white emulsion. The grain size of said microcapsule prepared by using the invented method is 20-4 micrometers.
Description
Technical field
The present invention relates to a kind of weaving aromatic micro-capsule, especially relate to a kind of preparation of polyurothane antibiotic aromatic micro-capsule.
Background technology
Aromatic micro-capsule is by spices and be wrapped in outer capsule material and constitute, and particle diameter is at 20-40um.Aromatic micro-capsule is widely used in textile industry, and main effect has: reduce spices and extraneous contacting, thereby prevent that the spices volatilization is too fast, reduce fragrance loss, have certain slow releasing function, and prolong fragrance remaining time.Its capsule material of aromatic micro-capsule in the past adopts melamino-formaldehyde resinoid, materials such as gelatin mostly.Because there is the cyst wall instability in it, problems such as porosity is irregular, therefore its slow release is not high, spices fragrance remaining time with its parcel is short, and these materials adopt the preparation of oiliness system mostly, and some monomer free does not meet environmental requirement sometimes, and do not have antibacterial functions, be easy to breed bacteria and lost efficacy.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of fragrance slow release higher, environmentally friendly, have the preparation method of preparation of the polyurothane antibiotic aromatic micro-capsule of antibacterial functions.
The object of the present invention is achieved like this: a kind of preparation of polyurothane antibiotic aromatic micro-capsule is characterized in that: the oil phase of the preparation material of polyurothane antibiotic aromatic micro-capsule is made up of polyisocyanates, essence, inorganic antiseptic and cyclohexane; Water is made up of NaOH, sodium alginate and deionized water; Preparation technology adds polyethylene glycol and acetone in above-mentioned oil phase, be added dropwise to aqueous phase after the mixing, 1.5-2 hour drip off, mixing speed is at 400-600 rev/min, temperature remains on 40-60 ℃, after dripping off, be warming up to 50-70 ℃, reacted 1-1.5 hour, the product suction filtration that obtains, product is a white emulsion, and the proportioning of the each component of its preparation material is:
Oil phase:
Polyisocyanates 3-4 weight portion
Essence 15-20 weight portion
Inorganic antiseptic 1-2 weight portion
Cyclohexane 20-25ml;
Water:
NaOH 0.3-0.5 weight portion
Sodium alginate 0.3-0.5 weight portion
Deionized water 200 weight portions;
Polyethylene glycol 3～5 weight portions.
Polyisocyanates of the present invention can be IPDI, TDI or HDI.
Inorganic antiseptic of the present invention can be nano silicon oxide, titanium oxide or the basic zirconium phosphate of load silver ion, zinc ion; Molecular weight polyethylene glycol can be 400,600 or 800.
Because polyisocyanates belongs to an indispensable monomer of polyurethane, can give the polyureas resilience, high-modulus, the present invention uses polyisocyanates that spices is coated, and the aromatic micro-capsule fragrance slow release that obtains is higher, environmentally friendly, environmental protection more, and the capsule material has certain resilience, is easy to processing; Add inorganic antiseptic, make product have antibacterial functions, these microcapsules are to Escherichia coli, staphylococcus aureus, and Candida albicans has extremely strong antibacterial ability.
