Problems solved by technology

The disadvantages of these inorganic copper fungicides are: poor safety, should not be mixed with other pesticides, otherwise it is easy to cause phytotoxicity; easy to cause outbreaks of mites after use, etc.; copper ion utilization rate is low, and the duration is short
Its disadvantage is firstly that it uses a large amount of heavy oil, which greatly increases the cost of the product (it is estimated that the cost of obtaining the same content of copper rosinate is more than three times the cost of the aqueous phase method), which reduces the cost performance of the product; Secondly, heavy oil, as an organic solvent, has serious pollution to the environment. At present, the country has suspended the registration of new emulsifiable oil products in the pesticide registration process.
[0006] Simultaneously, the Chinese invention patent application that the patent application number is 200510043522.0 discloses a kind of rosinic acid copper water emulsion and preparation method thereof, but the solvent that it uses also belongs to organic solvent, also does not really solve the environmental pollution that uses organic solvent to bring and high cost problem

Abstract

The invention discloses a copper rosinate suspending agent and a preparation method thereof. The copper rosinate suspending agent comprises the following components in percentage by weight: 10-50% of copper rosinate raw powder, 3-10% of dispersing agent, 0.1-1.5% of thickening agent, 2-5% of anti-freezing agent and the balance of water. By adoption of the copper rosinate suspending agent and the preparation method thereof, a whole production process is finished once, the production period is short, the production efficiency is high, and the energy consumption in production is low; no waste liquid, waste slag or waste gas is generated in the whole production process, so that the environmental friendliness is good; a prepared suspending agent is a water-based preparation without any organic solvent, therefore, the suspending agent is safe, environment-friendly, relatively low in cost and convenient to use and does not cause dust pollution.

Description

technical field [0001] The invention relates to a copper rosinate suspending agent and a preparation method thereof. Background technique [0002] At present, broad-spectrum copper fungicides commonly used in agriculture are generally inorganic copper fungicides, such as common Bordeaux mixture, copper hydroxide, copper oxychloride, cuprous oxide, etc. The disadvantages of these inorganic copper fungicides are: poor safety, should not be mixed with other pesticides, otherwise it is easy to cause phytotoxicity; easy to cause mites outbreak after use, etc.; copper ion utilization rate is low, and the duration is short. [0003] Copper rosinate is a new type of copper preparation bactericidal pesticide with high efficiency, low toxicity and broad spectrum, which has the new characteristics of long-lasting effect and convenient use. Copper rosinate has dual functions of prevention, protection and treatment. It can be used to prevent and control common plant diseases caused by v...
