Problems solved by technology

[0002] The drip irrigation belt is made of polyvinyl chloride as the main raw material, by adding carbon black, plasticizer, lubricant, processing aid, heat stabilizer, calcium carbonate (CaCO 3 ) and other auxiliary materials, it has the advantages of good tensile strength, flame retardancy, corrosion resistance, electrical insulation performance, etc., but it also has the disadvantages of being intolerant to insect bites and short service life.
Because it is easily bitten by pests during use, and tearing damage occurs, its application is greatly limited

Abstract

The invention discloses a modified anti-pest-biting polyvinyl chloride drip irrigation belt applied to the field of agricultural water-saving irrigation facilities. The modified anti-pest-biting polyvinyl chloride drip irrigation belt is prepared from, by mass, 0.75-1.5 parts of carbon black, 15-35 parts of plasticizer, 0.5-2 parts of lubricating agents, 0.3-3 parts of processing aids, 0.5-2 parts of heat stabilizers, 10-25 parts of calcium carbonate (CaCO3)10, 0.05-0.1 part of deltamethrin and 60-75 parts of polyvinyl chloride. According to the modified anti-pest-biting polyvinyl chloride drip irrigation belt, by adding the deltamethrin, the insecticidal spectrum is wide, the effect is achieved on multiple pests such as lepidoptera pests, orthoptera pests, thysanoptera pests, hemiptera pests, diptera pests and coleopteran pests, and therefore the modified polyvinyl chloride drip irrigation belt has the excellent comprehensive performance; compared with a common polyvinyl chloride drip irrigation belt, the modified anti-pest-biting polyvinyl chloride drip irrigation belt has the advantages that pest biting is effectively prevented, the service life of the drip irrigation belt is guaranteed, and the labor cost of pesticide spraying in agricultural planting is lowered.
