Abstract

The invention relates to a low-molecular-weight polyolefin emulsion applied to a film-forming agent of a seed coating agent and a preparation method thereof. The emulsion is prepared from the following raw materials in parts by weight: 20-40 parts of low molecular weight polyolefin; 2-6 parts of emulsifier; 1-2 parts of co-emulsifier; 1-2 parts of wetting agent; 0.1-2 parts of preservative 0.2 parts; 50‑75 parts of water. A kind of low-molecular-weight polyolefin emulsion applied to the film-forming agent of the seed coating agent of the present invention can be enriched on the surface of the seed coating film to form a hard and slippery isolation layer, thereby preventing the adhesion between the seed coating films and improving the The hardness and smoothness of the seed coating film are improved, and the seed coating film added with polyolefin emulsion is smoother and harder, and the abrasion resistance is obviously improved.

Description

technical field [0001] The invention relates to the technical field of pesticide seed coating, in particular to a low-molecular-weight polyolefin emulsion applied to a film-forming agent of a seed coating agent and a preparation method thereof. Background technique [0002] Seed coating agent (seed coating agent) is processed from related medicaments, nutrients, film-forming agents, dispersants and auxiliary agents. It has certain strength and permeability and can be directly coated on the surface of seeds. It has the functions of seed disinfection, prevention and control of pests and rodents, slow release of fertilizers, avoiding damage to natural enemies, reducing environmental pollution, and improving crop resistance. It can increase seed germination rate, enhance disease resistance and insect resistance, cultivate strong seedlings, The purpose of increasing production and income. Its main ingredients include pesticide raw materials and film-forming agents, wetting and d...
