Long-effective insect prevention fiber and insect prevention net as well as preparation method thereof

Abstract

The invention relates to a long-effective insect prevention fiber which is characterized by being prepared by using polyolefin resin as a base material, and adding the following assistant materials accounting for the weight percentage of the base material into the base material: 0.001-10 percent of melamine resin, 0.01-2 percent of permethrin and 0.01-0.5 percent of deltamethrin or 0.01-1.5 percent of cyhalothrin. The invention also discloses a preparation method of the long-effective insect prevention fiber and a long-effective insect prevention net. The long-effective insect prevention fiber or the insect prevention net has the characteristics of long effective time, low cost and the like. The insect prevention fiber not only can effectively prevent and dispel insects, but also can prevent insecticides from being in direct contact with crops. Aiming at the characteristic of outdoor application, the insect prevention fiber sufficiently extends the seepage of pyrethrin from the inner part of the fiber, reduces loss due to rain pouring and vaporization, and increases the effective period of the product. The insect prevention fiber is mainly applied to prevention nets for production in agriculture, forest industry and animal industry, namely insect prevention nets for agricultural big-arch shelters, insect prevention nets for trees and insect prevention nets for animal industry.

Description

technical field [0001] The invention relates to a fiber, in particular to a long-acting insect-proof fiber for agriculture and forestry; the invention also relates to an insect-proof net and a production method of the long-acting insect-proof fiber. Background technique [0002] In the process of agricultural and forestry planting, the success or failure of pest control measures is directly related to the success or failure of planting. The general practice in the prior art is to directly spray pesticides to crops to deworm when insect pests occur or are about to occur. The crops in one season need to be sprayed multiple times, and the pesticides are in direct contact with the crops, which is prone to pesticide residues. Moreover, the method of spraying pesticides to eliminate insects cannot expel flying birds, mosquitoes and flies. When crops or fruits mature, flying birds peck and mosquitoes breed will greatly reduce crop yields and affect the economic benefits of plantin...

Problems solved by technology

The crops in one season need to be sprayed many times, and the pesticides are in direct contact with the crops, which is prone to pesticide residues

Moreover, the use of pesticide spraying to eliminate insects cannot drive away flying birds, mosquitoes and flies. When crops or fruits mature, flying birds peck and mosquitoes breed will greatly reduce crop yields and affect the economic benefits of planting.
