Insect killing paste
The present invention relates to a kind of medicine of killing sanitary insect pest, specifically a kind of medicine of killing various pests such as cockroach, ant, fly, termite.
Cockroach is a kind of spreading disease, serious harm people's lives and healthy a kind of sanitary insect pest, and it haunts about kitchen, dining room, food processing factory etc. and locates, and it relatively likes sweet, fragrant, the soft food of food, very troublesome.The deinsectization articles for use kind of killing cockroach on the market is a lot, and the method for various granules, tablet, propellant and some physics is arranged.Have his own strong points, but one one kinds of existing effects of luring preferably and killing are not arranged as yet, and the deinsectization articles for use that keep better effects are chronically arranged simultaneously.United States Patent (USP) (USP4,812,310-1989) a kind of insect killing paste prescription of killing cockroach is disclosed, Maxforce is a kind of lotion of killing cockroach that better stomach poison function is arranged, but this lotion in a short time will soon be dry and cracked, greatly reduces its allure.
The purpose of this invention is to provide a kind of allure and poisoning power is strong, can make lotion keep long-term soft simultaneously again, surface wettability, thus make it that insect killing paste agent prescription of longer residual effect and preparation method thereof be arranged.
The insecticide composition that the present invention proposes serves as main poisoning thing with the orthene insecticide of 0.01-3%, other has better stomach poison function to cockroach also available chlopyrifos or decis etc., but do not have the insecticide of food refusal effect, also can select other insecticide for use according to the requirement of killing different insects.Adding 0-50% forming agent, 2-50% water, 5-70% softening agent, 10-70% attractant, 0-1% preservative and 0-1% antioxidant forms.Wherein forming agent is generally carboxymethyl cellulose and agar etc., and softening agent is a glycerine, and attractant is dry powder, corn flour, analysis for soybean powder of sucrose, milk powder, dusty yeast, honey, maltose, beef extract and various animal visceras etc.Preservative is methyl p-hydroxybenzoate, propylparaben or sorbic acid etc.Antioxidant is BHT (2, the 6-2 tert-butyl group-4-methylphenol).
The preparation method is as follows:
In first container, the softening agent that adds forming agent in the A component, water, attractant and 70% by weight percentage successively mixes heated and stirred, temperature remains on 80-100 ℃, to be formed dose dissolves, and each component fully mixes, and continues insulation under the 80-90 ℃ of condition.Preservative, antioxidant and remaining 30% softening agent with the B component in another container mix the back heating, and remain under the 70-90 ℃ of condition standby.Insecticide is joined in the A component, add the B component while stirring simultaneously, after waiting to stir, stop heating, and in stirring, make temperature reduce to room temperature rapidly.At this moment, mixture lotion.Also can be in plastic containers with the can immediately of this lotion, treat that its cooling curing forms the soft lotion of definite shape, or be poured into while hot in the special mould, stripping forming again after the cooling.Can change the denseness of its lotion according to different instructions for uses, increase the content of forming agent, can increase the denseness of lotion, otherwise reduce the consumption of forming agent, the consumption that increases softening agent then can reduce the denseness of lotion, the polytype insect killing paste of the suitable preparation of this program.
The present invention can be prepared into the insect killing paste that matches with the cockroach feeding habit.Therefore, allure and poisoning power are strong, and have characteristics such as residual effect is lasting and not dry for a long time.Because softening agent has used glycerine in the prescription, can keep moistening for a long time at normal temperatures, and it is had with the similar profile state of ointment, thereby extremely strong to the palatability of various cockroaches.A large amount of take in malicious cream and be detained in the deadly cockroach body a certain amount of insecticide is arranged, because of cockroach has the habit of the similar corpse of ingesting, so after cockroach eats this corpse, also can be poisoned to death, this is referred to as chain effect, and the experiment of table one will further confirm positive effect of the present invention.
The chain effect of table one, insect killing paste
