Abstract

The invention discloses masterbatch for a mosquito-repelling net, comprising a granular main body, wherein the main body contains thermoplastic resin and alphamethrin. The processing method comprises the following steps of: 1), adding thermoplastic resin, alphamethrin, antioxidant and stabilizer; 2), stirring the materials for 40-50min to uniformly mix; and 3), sending the stirred mixture to a screw melting extruder to shear, melt and disperse, and finally, extruding, cooling and grain-sized dicing to obtain needed masterbatch. Compared with the prior art, the masterbatch has the advantage that alphamethrin is taken as pesticide, and trace amount of alphamethrin pesticide is effectively mixed to thermoplastic resin by setting process parameters during the processing according to characteristics of alphamethrin so as to realize slow and effective release. The mosquito-repelling net made of the masterbatch has the advantages of long-acting performance, safety and no toxicity for the human body and water washing resistance.

Description

technical field [0001] The invention belongs to the field of preparation of color masterbatches, in particular to a color masterbatch used for mosquito repelling mosquito nets. Background technique [0002] It shows that in life, especially when the weather is hot and humid, mosquito bites have caused great troubles to people, and mosquitoes can spread diseases through contact with human blood, such as malaria, dengue fever, meningitis, etc., affecting people's health. [0003] The traditional anti-mosquito means are mainly driven by smoke, but it is more harmful to the human body. Although with the development of technology, electric heating and low-toxic or non-toxic organic mosquito repellents are generally used to directly volatilize to generate mosquito repellent gas. The method can only be used indoors, and the mosquito repellent gas cannot reach a sufficient concentration to repel mosquitoes outdoors due to the fast air flow. Another kind of anti-mosquito method is t...
