Problems solved by technology

[0003] In order to overcome the above-mentioned defects, the purpose of the present invention is to provide a kind of macromolecular material and preparation method thereof for coating feed additives, synthesized the ternary copolymerization macromolecule sensitive to pH, due to its own special molecular structure characteristics and its The pH sensitive range makes it more firmly combined with molecules such as rumen-passing additives or drugs, and can directly form a coating film on the surface of rumen-passing additives or drugs, and ensure that the polymer coating material is compatible with feed additives or The drug molecule does not detach, thus overcoming the shortcomings of the weak combination of the blended polymer coating material and the coated product, and the wide pH sensitivity range of some other synthetic polymer coating materials

Abstract

A synthetic polymer material for coating feed additive and its preparation are disclosed. The process is carried out by: taking styrene, diacetyl-pyridine or acrylic amide or methyl-acrylic dimethylamine carbethoxy monomer as raw materials, taking K2S208 as evocating agent and synthesizing to obtain ternary irregular co-polymer. It's stable, has better pH sensitivity and damp resistance. It can avoid feed additive or medicine from being decomposed early.

Description

technical field [0001] The invention belongs to a polymer copolymer, in particular to a polymer material for coating feed additives and a preparation method thereof. Background technique: [0002] The additives or medicines fed to ruminants are decomposed prematurely in the rumen, which affects the absorption of active ingredients such as feed additives or medicines by the abomasum, thereby increasing the feeding cost. In order to protect the additives and drugs fed to ruminants without loss or as little loss as possible when they pass through the rumen, one of the commonly used methods is to use some biocompatible polymer coating materials to coat the additives or drugs. It is then fed to ruminants. At present, the polymer coating materials used in China are blended polymers formed by simply blending natural polymers and some resins, such as the patent "CN95107793.7 A protective film for rumen-passing preparations" applied by the Beijing Institute of Nutrient Sources ". ...
