Abstract
The invention relates to a method for preparing a botanical anti-mosquito microcapsule finishing agent, which comprises the following steps: (1) plant essential oil and monomeric isocyanate with the mass ratio of between 1 to 1 and 1 to 2.5 form an organic phase; (2) 2 to 2.5 percent polyvinyl alcohol and 0.15 to 0.75 percent sodium alginate form an aqueous phase; (3) the organic phase is injected into the aqueous phase, the mass ratio of the organic phase to the aqueous phase is 10 to 90, and the organic phase and the aqueous phase are emulsified with the rate of between 9,000 and 11,000r/min to form an oil-in-water emulsion; and (4) the oil-in-water emulsion is transferred into a reaction kettle, the monomeric isocyanate and a catalyst, namely dibutyl tin laurate are dripped into the oil-in-water emulsion, the stirring rate of between 800 and 2,000r/min is maintained, and the mixture reacts for 2 to 3 hours at room temperature and then reacts for 1 to 2 hours by dripping a curing agent into the mixture to obtain the botanical anti-mosquito microcapsule finishing agent. The preparation method has the advantages that the preparation method is simple, has strong maneuverability and low cost, and is suitable for industrialized production.
Description
Technical field
The invention belongs to the preparation field of antimosquito finishing agent, particularly relate to a kind of preparation method of plant source microcapsule dressing agent for preventing mosquito.
Background technology
Mosquito sucks blood, harasses the sleep except that directly stining thorn, also can propagate multiple disease. and the mosquito of China passes disease and mainly contains malaria, lymph filariasis, Japanese Type-B encephalitis and dengue fever (or dengue hemorrhagic fever) four classes, also has yellow fever and various equine encephalitis etc. in addition.The behavior of sucking blood of hematophagus is the process of a complexity, and repellant mainly acts on the osmoreceptor of insect feeler, influences the impression of insect to host's smell, thereby the people is avoided by insect bites or attack.Bring into play repellent action by the sense of smell that stimulates insect, mosquito contact human body can effectively prevent mosquito near human body, even also can be escaped, fly away before sucking blood, reason is the nerve ending that contact back repellent active ingredient acts on mosquito, makes mosquito that action entanglement and action obstacle take place.The plant source mosquito repellant is compared with chemical repellant, have the degraded rapid, residual less, to characteristics such as the person poultry toxicity are low.Plants essential oil is the inferior natural disposition material in the plant, these materials be in the long-term and insect coevolution process of plant for resisting the chemical substance that the behavior of insect herbivore produces, insect is had tag, stomach toxicity, avoid keep away, multiple biologically actives such as food refusal and inhibition growth.The cry of advocating " back to nature " " sustainable development " along with global range is strong day by day, and the natural plant source mosquito repellant of exploitation safety has also caused extensive concern.
Summary of the invention
Technical problem to be solved by this invention provides a kind of preparation method of plant source microcapsule dressing agent for preventing mosquito, and this method is simple, and is workable, and cost is low, is fit to suitability for industrialized production.
The preparation method of a kind of plant source microcapsule dressing agent for preventing mosquito of the present invention comprises:

(3) organic facies is injected aqueous phase, the mass ratio of water and organic facies is 10:90, with 9000-11000r/min emulsification 10-20min, forms O/w emulsion;
(4) above-mentioned O/w emulsion is changed in the reactor, drip monomer polyethylene glycol (consumption is 0.5 times of molal quantity of vulcabond) and 0.02% catalyst dibutyl tin dilaurate, keep stir speed (S.S.) 800-2000r/min, and after reacting 2-3 hour under the room temperature, drip the 0.2-0.24g curing agent and reacted again 1-2 hour, can make plant source microcapsule anophelifuge finishing agent.
Plants essential oil is bay leaves oil, geranium oil, pine tar, cedar wood oil or citronellal in the described step (1).
In the described step (1) monomeric diisocyanate be 2,4 toluene di-isocyanate(TDI)s, 2,6 toluene di-isocyanate(TDI)s, diphenyl methane-4,4 '-vulcabond or triphenyl methane-4,4 ' 4 " triisocyanate.
Monomeric diisocyanate is 2,4 toluene di-isocyanate(TDI)s in the described step (1).
The monomer molecular weight polyethylene glycol is 400kg/kmol in the described step (4).
Curing agent is ethylenediamine or benzenediol in the described step (4).
Prepared microcapsule can directly apply to the back arrangement of textile, and is convenient and swift, and running product safety is particularly suitable for developing the textile that underwear, skirt, socks, bedding etc. and human body directly contact.
Beneficial effect
(1) equipment required for the present invention is simple, and cost is low, and is easy to operate, can be mass-produced.
(2) the plant source microcapsule anophelifuge finishing agent product of the present invention's preparation is stable, and capsules disperse is good, and narrow particle size distribution is by the size of the controlled glue capsule of change condition.
