Abstract
The invention discloses an environment-friendly polyhydroxyvalerate mosquito-repellent tablet and a preparation method thereof. Polyhydroxyvalerate base materials and natural plant essential oil in the mosquito-repellent tablet comprise the following components in percentage by mass: 80-99.5wt% of polyhydroxyvalerate, 0.1-10wt% of wormwood, 0.1-10wt% of geranium, 0.1-10wt% of mint, 0.1-10wt% of holly and 0.1-10wt% of lemon. The preparation method comprises the following steps: directly adding the natural plant essential oil prepared from different components into polyhydroxyvalerate resin, carrying out uniform stirring, and molding differently-shaped mosquito-repellent products by an injection molding machine. The mosquito-repellent tablet has a unique mosquito-repellent effect when being naturally placed, and is free of toxicity and pollution; meanwhile, polyhydroxyvalerate is an environment-friendly degradable material, so that the mosquito-repellent tablet can be thrown away as daily garbage after being used, and the damage to the environment is avoided.
Description
Technical field
The present invention relates to a kind of environmentally friendly poly-hydroxyl valerate mosquito-dispelling tablet and preparation method.
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.
Poly-hydroxyl valerate (PHV), is the aliphatic copolyester of the different structure synthesized by various carbon source through fermentation by microorganism, is a kind of thermoplastic polyester be widespread in nature, is especially everlasting between bacterial cell and finds.Many physical properties of PHV and mechanical property and polypropylene plastics close, but it has biological degradability and biocompatibility, in vivo can degradable one-tenth beta-hydroxy-butanoic acid, carbonic acid gas and water.The device of harmless decomposition in human body after drug delivery system, implant and some recoveries from illness is can be used for the material that this biological plastics is made, but vs polypropylene, PHV is harder, and more crisp.Conventional plastic degraded needs 100 years, as long as within 12 months, just can decompose with the product that PHV produces, what discharge only has water and carbonic acid gas.This series products can be used for the industries such as packaging for foodstuff, cosmetics, medicine, health and agricultural.Pure natural plant essential oil is added to injection mo(u)lding in poly-hydroxyl valerate matrix resin, following advantage can be reached: a, poly-hydroxyl valerate become the effective carrier of natural plant essential oils, be convenient to the product that injection moulding or hot pressing become 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, poly-hydroxyl valerate product, can effectively become to catching up with mosquito in certain space, avoid being bitten; C, plants essential oil to be dispersed in poly-hydroxyl valerate product, to have delayed its release and volatilizes, mosquito repellent function can have been played for a long time; D, poly-hydroxyl valerate and natural plant essential oils all belong to Degradable environment protection series products, Nonpoisonous, non-environmental-pollution, are applicable to all kinds of crowd.
Therefore, environmentally friendly poly-hydroxyl valerate mosquito-dispelling tablet newly developed, its effect is because the difference of active ingredient, repel mosquitoes is changed into from the mosquito that kills of traditional mosquito repellent 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.
Summary of the invention
A kind of environmentally friendly poly-hydroxyl valerate mosquito-dispelling tablet and preparation method are the object of the present invention is to provide.Product environment friendly of the present invention is gathered hydroxyl valerate mosquito-dispelling tablet and 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.
