Description

 Deworming masterbatch composition and method for producing an insect repellent masterbatch composition  

The invention relates to an insect repellent masterbatch composition and a method for producing an insect repellent masterbatch composition, in particular to an insect repellent which can effectively deworm and even disinfesate the natural pyrethroid. A granule composition and a method for producing an insect repellent masterbatch composition.

Taiwan is located in the subtropical zone and has a warm and humid climate. It is suitable for the growth of various crops and relatively a breeding ground for pests and diseases. However, as the global population increases, the demand for agricultural products increases, but crops provide humans under the harm of insects. The yield of crops consumed is reduced. At present, farmers mainly spray pesticides on crops to avoid insect caries. Among them, organophosphorus and carbamate are the most commonly used pesticides. The main reason is that they can effectively kill insects and have half life in natural humidity and temperature. short. However, these two types of pesticides have a great adverse effect on human health, which will cause an increase in carcinogenic rate, which is neurotoxic in the body, causing muscle paralysis, resulting in difficulty in breathing, decreased heart rate and blurred vision, and death. Therefore, finding ways to achieve natural deworming or pest control is an important issue that must be addressed to reduce or eliminate the use of pesticides.

There is already a functional fiber that provides a fiber with a long-lasting insect-repellent effect, but it is a chemical pyrethrin such as deltamethrin or permethrin, but its chemical pyrethroids. May be harmful to the human body, for example, brain and motor nerve disorders, immune system abnormalities, allergies, carcinogenicity, reproductive toxicity or environmental hormonal effects. In general, the recommended human body allows the upper limit of exposure to pyrethroids to be 5 mg per cubic meter.

Although natural pyrethrins are highly fat-soluble, they are easily metabolized and therefore do not form cumulative toxic effects in humans. However, they are easily decomposed by sunlight and are easily decomposed into non-toxic products in water. The pyrethrin is difficult to apply to long-term daily necessities. Due to the climatic factors of the environment, outdoor wind and rain, and ultraviolet rays, the natural pyrethrin contained in the product is accelerated and decomposed.

EXPERIMENTAL RESULTS 2-2: Decomposition of a deworming foaming mat without modified nano-mica at atmospheric pressure

An insect-repellent foaming pad (area 5 × 5 cm ^ 2 , 5 g, thickness 0.2 cm, density 0.94, random sample) without modified nano mica was placed under a confined space of atmospheric pressure (60* 60*60 cm3) For three days, 0.01, 0.05 and 0.09 mg of natural pyrethrin or a mixture of air per cubic centimeter of air detected in the three confined spaces with an electronic capture detector. The concentration of chemical pyrethrin is much lower than the allowable concentration in the air set by the Labor Committee of the Executive Yuan (5 mg per cubic centimeter of air), indicating that the deworming foam pad without modified nano-mica is in one The amount of natural pyrethrin or chemical pyrethrin which is decomposed and released under atmospheric pressure and which is decomposed and released, but the average error is found to be quite large among the three random samples, and the cause of the result is mixed. Uneven.

Experimental Results 2-3: Destruction Experiment

The deworming foaming pad (area 5×5 cm ^ 2 , 5 g, thickness 0.2 cm, density 0.94, random sample) without modified nano mica was used as a destructive experiment, and the modified mica mica was not used. The insect foaming pad was immersed in 1 liter of sulfuric acid solution (1 mol/L) for two hours, and then the concentration of natural pyrethrin or chemical pyrethrin in the solution was analyzed by HPLC, and the natural pyrethrum of the three solutions was found. The concentration of fine or chemical pyrethrin is 0.02, 0.03 and 0.05 ppm, respectively, so the insecticidal foam pad without modified nano-mica can be decomposed by acid and release natural pyrethrin or chemical pyrethrin. However, the average error was found to be quite large among the three random samples, and the reason for the result was due to uneven mixing.

The dispersant formulation of the present invention was judged from Experiment 1 and Experiment 2 (comprising 0.05 to 30 parts by weight of nano calcium carbonate and 35 to 80 parts by weight of the dispersant with respect to 100 parts by weight of the dispersant) Nano-mica and 0.05~20 parts by weight of nano-cerium oxide) have better mixing effect than pure calcium carbonate as dispersing agent. In addition, the inventors found in the research and development process that improper dispersing agent or dispersion was used. There are three phenomena in the composition of the deworming masterbatch prepared when the proportion of the formulation is incorrect. One is that the pyrethrin is not released in the deworming masterbatch composition; the other is in the deworming masterbatch composition. The pyrethrum is mixed and uneven; the third is the rate of pyrethrin release in the deworming masterbatch composition.

An insect repellent masterbatch composition according to the present invention is capable of producing an insect-repellent fiber or a foaming mat having natural pyrethrin or/and chemical pyrethrin through spinning, extrusion or other forming techniques; Worm fiber is used to make single yarn, monofilament, double yarn, mixed yarn, short silk, filament fabric with insect repellent or pest control; and / or used to make box nets and yarns with insect repellent or insecticidal function Polyester products of mesh, yarn bag, non-woven fabric, gauze, gauze and filter.
