Problems solved by technology

[0002] Adhering permethrin compounds on fabrics by dipping method can kill harmful insects, while the existing methods of manufacturing insect-repellent fabrics are to first soak the fabrics in insect-repellent liquid, which usually requires a long time of soaking to allow insect-repellent liquid to penetrate or adhere On the surface of the fabric, another method is to heat, dry and solidify the fabric soaked in the insect repellent liquid, so that the insect repellent liquid forms a film on the surface of the fabric, but heating the fabric will cause part of the insect repellent liquid to disintegrate or sublimate, so now The insect-proof net in the prior art is usually less than 5% to the adsorption of insect-proof liquid

Embodiment 1

[0031] Warping and weaving with 100D polyester low elastic yarn has a grammage of 40G / M 2 The mesh fabric is washed and dried at a temperature below 110 degrees Celsius. Then prepare the insect-proof styling liquid, get the weight percent content to be respectively 62% deltamethrin, 20% urea-formaldehyde resin, 15% dioctyl maleate sodium sulfonate, 3% emulsifier as the insect-proof styling liquid raw materials. Put the urea-formaldehyde resin into the methanol solution with a concentration greater than or equal to 99% according to the ratio of 1:40 by weight, and prepare the methanol solution of the urea-formaldehyde resin; In methanol solution, wherein the emulsifier contains 23% by weight of fatty alcohol polyoxyethylene ether, 27% of alkylphenol polyoxyethylene ether, and 50% of nonylphenol polyoxyethylene ether, stir evenly to obtain insect-proof stereotypes liquid. Mix the insect-proof styling liquid and water evenly in a ratio of 1:3, and then coat the mixture of the ...

Embodiment 2

[0033] Weave a mesh fabric with 75D polyester low elastic yarn, wash and dry it for later use. Prepare insect-proof styling liquid, by weight percent, the raw materials include 60% deltamethrin, 20% urea-formaldehyde resin, 15% sodium butylnaphthalene sulfonate, and 5% emulsifier, which includes 25% by weight of fatty alcohol polyoxyethylene ether, 25% by weight of alkylphenol polyoxyethylene ether, and 50% by weight of nonylphenol polyoxyethylene ether. Dissolve the urea-formaldehyde resin in the ethanol solution with a concentration greater than 98% according to the weight ratio of 1:30, and prepare the ethanol solution of the urea-formaldehyde resin, then put deltamethrin, sodium butylnaphthalene sulfonate and emulsifier into the above-mentioned urea-formaldehyde In the ethanol solution of the resin, the insect-proof sizing liquid is prepared. Finally, the insect-proof sizing liquid and water are mixed at a ratio of 1:5, and then the mixed liquid is coated on the mesh fabri...

Abstract

The invention relates to a method for manufacturing insect-proof net. The method includes the following steps: A, preparing insect-proof sizing solution,I, raw materials of the insect-proof sizing solution include: pyrethrin, urea resin, penetrant and emulsifier, wherein the emulsifier contains fatty alcohol-polyoxyethylene ether, alkyl phenol polyoxyethylene ether and nonyl phenol polyoxyehyleneether; II, urea resin in formula ratio is dissolved in methyl alcohol or ethyl alcohol, thus forming alcoholic solution of urea resin; III, pyrethrin, penetrant and emulsifier are added into the alcoholic solution of urea resin in formula ratio, thus obtaining the insect-proof sizing solution; IV, the insect-proof sizing solution is uniformly mixed with water by weight ratio of 1:(3-5); B, coating mixture of insect-proof sizing solution and water on a network fabric; and C, sizing. In the invention, penetrant and emulsifier are added into the insect-proof sizing solution, so that pyrethrin playing a main role in insecticidal action can be accelerated to penetrate into the interior of fiber, and the insect-proof net has the advantages of high production efficiency and good insecticidal effect.

Description

technical field [0001] The invention relates to a method for manufacturing an agricultural insect-proof net, which can be used in the fields of manufacturing agricultural greenhouse nets, fruit insect-proof net bags, tree insect-removing protective nets, and the like.
