Insect-prevention masterbatch for manufacturing large-scale grain storage device

Abstract

The invention belongs to the technical field of chemical synthesis, and specifically relates to an insect-prevention masterbatch for manufacturing a large-scale grain storage device. The insect-prevention masterbatch is made from the following raw materials, by weight percentage, 30-35% of an insect-prevention traditional Chinese medicine, 45-60% of a main material, 3-5% of a coupling agent, 3-5% of polyethylene wax and 2-10% of gas-phase white carbon black. The insect-prevention traditional Chinese medicine is one or more of pericarpium zanthoxyli, mugwort, litsea cubeba, polygonum flaccidam, calamus, camphor trees, pyrethrum, ailanthus altissima leaves and Sichuan chinaberry leaves. The manufactured grain storage device can effectively prevent insects from biting and prevent damage by rats, allows grain to be saved, and prolongs the storage time of grain. The insect-prevention masterbatch has no toxic or side effect on the human body, is low in processing cost, and simple in manufacture principle and is safe and eco-friendly.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis, and in particular relates to an anti-insect masterbatch for preparing large-scale grain storage equipment. Background technique [0002] Today, with the rapid development of science and technology, food is still an important commodity and material. Food is the most important thing for the people. It is especially important to store food well and prevent insects from biting rats. Storage safety is very important to China's food security. Perfect storage facilities and technical support are necessary conditions for realizing food security. However, according to statistics, so far more than 50% of China's grain is stored in the hands of farmers. These farmers mainly use woven bags and gunny bags. , noodle bags, mats, and self-built granaries and other grain storage equipment to store grain. Most of these equipment are very simple and have poor grain storage performance. The problems of ro...

[0002] Today, with the rapid development of science and technology, food is still an important commodity and material. Food is the most important thing for the people. It is especially important to store food well and prevent insects from biting rats. Storage safety is very important to China's grain security. Perfect storage facilities and technical support are necessary conditions for realizing food security. However, according to statistics, so far more than 50% of China's grain is stored in the hands of farmers. These farmers mainly use woven bags and gunny bags. , noodle bags, mats, and self-built granaries and other grain storage equipment, most of these equipment are very simple, poor grain storage performance, and serious problems of rodents, insects, and mildew. According to data, the average annual loss of grain storage by farmers across the country is 8%, with an annual loss of 20 million tons of grain; at present, in order to reduce losses, depositors usually use drugs such as methadone powder, dioxin powder, and aluminum phosphide to repel insects and rodents, resulting in serious pesticide residues exceeding the standard. This kind of grain is processed into Consumption of the product will cause great harm to physical and mental health, especially aluminum phosphide, which reacts with carbon dioxide in the air to produce phosphine, which is a highly toxic gas that is fatal to humans and other animals

[0003] Therefore, we need a large-scale grain storage equipment, which can store grain together and avoid insect bites and rodents. At the same time, the same is true for large-scale grain stations. They are generally stored in good warehouses, but granaries cannot do this either. Prevent insects and rodents, so the country loses a lot of grain every year due to insects and rodents. In addition, some granaries use stainless steel structures, which are very expensive and impractical, and the follow-up repair costs are very high
