Abstract

A soaking-seed rice film forming agent belongs to the technical field of the pesticide, which aims at providing a soaking-seed rice film forming agent that has the excellent characteristics of the traditional film forming agent, can be soaked in the water, suitable for the seed-soaking sprout-promoting habit in the south of China and has definite prevention object. The key technical points of the soaking-seed rice film forming agent are the weight account of the raw material compositions of 150 to 320 styrene, 150 to 32 acrylic acid and the ester of the acrylic acid, 30 methacrylic acid and the ester of the methacrylic acid, 6 sodium dodecyl sulfate, 12 polyoxyethylene nonyl phenyl ether, 6 potassium peroxydisulfate, 18 tert-butyl mercaptan, 1.5 tetraglycol ester and 500 de-ionized water. The film forming agent is not dissolved and fractured in the water, which can improve the glass transition temperature, the membrana dermalis strength, the tensile strength, the rheological property, the water resistance and the film forming property of the seed coating agent. After trial test, the soaking-seed rice film forming agent is proved to have a favorable application effect after applied to the seed coating agent.
