Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0024] This specific embodiment adopts the following technical solutions: a film-forming agent for rice seed coating and a preparation method thereof, the following percentages are all mass percentages;

[0025] Weigh 24g of polyvinyl alcohol, add it into a four-necked bottle filled with 276g of distilled water (water temperature 80°C), stir while heating, until the polyvinyl alcohol is completely dissolved, about 3 hours, then pour it into a beaker, and seal it for storage;

[0026] Weigh 2g of sodium alginate, add it to a four-necked bottle filled with 98g of distilled w...

Abstract

The invention provides a film forming agent for rice seed coating and a preparation method thereof and relates to the technical field of suspension seed coating agents. The preparation method comprises the following steps: physically blending 1 percent to 8 percent of polyvinyl alcohol and 1 percent to 3 percent of sodium alginate and styrene to obtain a film-forming material for the rice seed coating; adding 1 percent to 8 percent of the polyvinyl alcohol and 1 percent to 3 percent of the sodium alginate and styrene into a dispersant at the ratio of (1 to 3) to (1 to 3) to (2 to 4); shearing on a high-speed tissue dispersing machine for 20min to 40min under revolutions of 10000rmp to 15000rpm, so as to obtain binary film-forming blending emulsion. The film forming agent has good air permeability and water permeability, has certain elasticity and meets the requirements of the rice seed coating; the film forming agent has a good film forming property and low releasing rate, the germination rate of rice seeds is high and the requirements of a rice suspension seed coating agent are met.

Description

technical field [0001] The invention relates to the technical field of suspension seed coating agents, in particular to a film-forming agent for coating rice seeds and a preparation method thereof. Background technique [0002] The film-forming agent is a seed coating agent that can effectively combine active ingredients such as insecticides, fungicides or fertilizers, and other inactive ingredients together, and form a film with capillary, expansive, or cracked channels on the surface of the seed. An important part of additives. After sowing, the active ingredients of this kind of seeds are slowly released through the membrane pores, and the drugs or other functional components are also slowly released, thereby killing the seeds themselves and the pests or other objects in the soil, and improving the germination rate and growth of the seeds. In rice (water) fields, the film-forming agent needs to have certain water resistance. At present, the film-forming agent of most ric...
