Description
Technical field
The present invention relates to a kind of polyurethane mosquito-dispelling tablet and preparation method thereof, belong to the technical field of household chemicals.
Background technology
Most area in the world, mosquito is serious public health problem.Estimate, about have 700,000,000 people to be infected various disease by mosquito every year, and in every 17 people, just have 1 people to die from the various diseases infected by mosquito.Especially in torrid areas, multiple infectious disease is often transmitted to the mankind by mosquito.
Along with the continuous progress of modern science and technology, various mosquito repellent product, as disc type, liquid, electric mosquito repellent, is developed and is sold to each corner of the mankind.But in the various types of mosquito repellent product that market is sold, its active ingredient is all the chemicals with chrysanthemum ester class insecticidal constituent, in burning or volatilization process, forms gas, except kill mosquitoes, certain injury is also existed to human body.But difference is only that their carrier is different, does not have a kind of anti-mosquito incense sheet to be completely harmless.
But improving constantly along with human living standard and quality of life, to the avirulence of mosquito repellent product, the requirement of property easy to use and crowd's applicability is also more and more higher.Adopt the Pure natural plant essential oil with mosquito repellent special efficacy, effectively repel mosquitoes can bite, avoid traditional mosquito repellent product gasification ingredient to damage human body while kill mosquitoes.
Polyurethane full name is polyurethanes, is the general designation of the macromolecular compound containing repetition carbamate groups on main chain.It is formed by organic diisocyanate or polyisocyanates and dihydroxy or polyol addition polymerization.Polyurethane material purposes is very wide, can replace rubber, plastics, and nylon etc. are applied to the every field that life is produced.Wherein MDI Series of Polyurethane is nonpoisonous and tasteless, belongs to environmental protection series products, is mainly used in the fields such as medicine equipment, packaging for foodstuff and communal facility.Preparing in polyurethane process, first by natural plant essential oils and base polyurethane prepolymer for use as blended, after add vulcanizing agent sulfuration, following advantage can be arrived: the polyurethane after a, sulfuration becomes the effective carrier of natural plant essential oils, be convenient to the product being prepared into various pattern, carry with or furnish; Be rich in a large amount of natural plant essential oils being rich in mosquito repellent function in b, polyurethane products, can effectively become to catching up with mosquito in certain space, avoid being bitten; C, plants essential oil to be dispersed in polyurethane product, to have delayed its release and volatilizes, mosquito repellent function can have been played for a long time; D, polyurethane and natural plant essential oils all belong to environmental protection series products, Nonpoisonous, non-environmental-pollution, are applicable to all kinds of crowd.
Therefore, polyurethane mosquito-dispelling tablet newly developed, because the difference of active ingredient, repel mosquitoes is changed into from the mosquito that kills of traditional product, to the injury of human body while avoiding desinsection, there is Nonpoisonous, non-environmental-pollution characteristic, the every field that family, office, travelling etc. are closely bound up with human lives can be widely used in.The present invention produces thus.
Summary of the invention
For the above-mentioned technical problem of prior art, the object of the present invention is to provide a kind of polyurethane mosquito-dispelling tablet and preparation method thereof, this mosquito-dispelling tablet is rich in natural plant essential oils composition, naturally place and just there is mosquito repellent function, and there is the excellent specific properties such as the simple and product design of Nonpoisonous, non-environmental-pollution, processing technology is diversified, the every field that family, office, travelling etc. are closely bound up with human lives can be widely used in.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of polyurethane mosquito-dispelling tablet, comprise polyurethane and natural plant essential oils, described natural plant essential oils comprises wormwood, geranium, peppermint, Chinese ilex and lemon, and the mass percent of described polyurethane, wormwood, geranium, peppermint, Chinese ilex and lemon is constructed as follows:
Polyurethane 80-95 wt.%
Wormwood 0.1-10 wt.%
Geranium 0.1-10 wt.%
Peppermint 0.1-10 wt.%
Chinese ilex 0.1-10 wt.%
Lemon 0.1-10 wt.%.
A preparation method for polyurethane mosquito-dispelling tablet, comprises the following steps:
(1), wormwood, geranium, peppermint, Chinese ilex and lemon are mixed in certain proportion natural become plants essential oil;
(2), the PAUR performed polymer of methyl diphenylene diisocyanate end-blocking is heated to 80-120 DEG C, ensure that performed polymer is liquid, pour the natural plant essential oils in a certain amount of step (1) into, mechanical agitation mixing 3-5 minute, property adds the vulcanizing agent 3 after thawing again, 3 '-dichloro-4,4,4 '-diphenylmethanediamiand, is uniformly mixed 1-3 minute;
(3), by the viscous liquid of step (2) gained directly pour in special die, then insert vulcanizing press sulfuration, namely die sinking obtains polyurethane mosquito-dispelling tablet.
The parameter of described vulcanizing press is: curing temperature 120-160 DEG C, sulfide stress 8-16MPa, cure time 10-60 minute.
Beneficial effect of the present invention is as follows:
Compared with the mosquito-dispelling tablet sold with existing market, polyurethane mosquito-dispelling tablet of the present invention is rich in natural essential oil composition, and Polyurethane carrier and plants essential oil all have human body without any side effects, is suitable for crowd extensive.This polyurethane anti-mosquito incense sheet is easy to use, can naturally place, and without the need to lighting or heating, is easy to carry or places, having long-term efficacy.In addition, it is different that processing mold pressed by polyurethane, can be prepared into various shape, as sheet, round shape, Irregular parts etc., also has processing technology simple, the advantage that cost is low.
