The invention discloses a special binder for a granulated fertilizer and a preparation method thereof, and belongs to the technical field of fertilizer additives, and the method comprises the following steps: taking corn starch as a raw material, carrying out acetic anhydride esterification to prepare starch acetate, and carrying out graft copolymerization on the starch acetate, acrylic acid and acrylamide monomers to form a starch graft polymer solution; then coating the surface of the acid-activated zeolite with chitosan through electrostatic self-assembly to obtain chitosan-modified zeolite, and finally mixing a starch grafted polymer solution with a chitosan-modified zeolite suspension, curing, drying and crushing to obtain the binder. An organic-inorganic hybrid structure is constructed through a flexible network of the starch grafted polymer and a rigid framework of the chitosan modified zeolite, a stable three-dimensional network is formed by utilizing multiple intermolecular acting force, the strength, pulverization resistance and slow release performance of fertilizer particles can be synchronously improved, and the preparation method is suitable for high-nitrogen compound fertilizer granulation and has a wide application prospect. The problem of bonding failure caused by ammonia release can be effectively solved, and the method has the advantages of good stability, environmental friendliness and simple and convenient process.

The invention relates to the technical field of adhesives, and provides an anti-bulge degradable leather plastic adhesive and a preparation method thereof.The anti-bulge degradable leather plastic adhesive is designed by adopting an epoxy-terminated polyurethane emulsion as a main body and adopting a composite formula of a fluorine-free polar modified epoxy compound dispersion liquid, starch acetate, a silane compound and cellulose nanocrystals as auxiliary materials. Through the processes of prepolymerization, end group sealing, modification reaction, cross-linking curing and the like, the synergistic effect among the components is realized, and the excellent performances that the interface bonding strength is greater than or equal to 12MPa, the water vapor transmission rate is less than or equal to 280g per square meter per day and the water absorption rate is less than or equal to 4.0% are realized; the technical problems that a traditional adhesive is poor in anti-swelling performance, insufficient in bonding strength and poor in water resistance are solved, and wide industrial application value is achieved.

The invention relates to the technical field of food processing, in particular to lactic-acid-containing tapioca balls and a preparation technology thereof.The lactic-acid-containing tapioca balls are composed of 40%-50% of cassava starch, 9%-15% of starch acetate, 4.5%-8% of a flavor modifier, 0.3%-0.5% of a structure stabilizer, 0.2%-0.3% of lactic acid, 0.25%-0.6% of gamma-polyglutamic acid and the balance water; the flavor improver comprises modified brown sugar, mogroside and modified bamboo charcoal powder. In order to solve the problems that the tapioca pearls are single in taste and difficult to coexist in fineness and chewiness, the tapioca pearls containing lactic acid provided by the invention not only improve the flavor level of the tapioca pearls, but also realize comprehensive improvement of the chewiness, fineness, freeze-thaw stability and shelf life of the tapioca pearls, can keep the taste and texture at low temperature, and are suitable for market promotion.

The invention relates to the technical field of adhesives, and discloses a low-temperature-resistant casein starch adhesive and a preparation method thereof.The low-temperature-resistant casein starch adhesive is prepared from, by weight, 100 parts of casein, 20-46 parts of starch acetate, 18-40 parts of polyvinyl alcohol, 35-50 parts of urea, 2-6 parts of siloxane cross-linking agent and the like. The siloxane cross-linking agent contains a large amount of epoxy groups and can react with amino groups of casein, hydroxyl groups of starch acetate and hydroxyl groups of polyvinyl alcohol, so that the cross-linking degree and cohesion of the casein starch glue are improved, and the adhesive has higher peel strength and adhesive property. After low-temperature and high-humidity treatment, the casein starch glue still has higher peel strength and excellent low-temperature and moisture resistance.

The invention discloses a feed additive for preventing and treating bacterial enteritis of poultry and a preparation method of the feed additive, and relates to the technical field of feed additives. The feed additive comprises the following raw materials: benzoic acid, a coating material, a synergist and an essential oil component, the synergist is prepared by mixing malic acid and fumaric acid; the essential oil component is prepared by mixing thymol, eugenol, oregano essential oil, trans-anethole and piperine; the coating material is prepared from hydroxypropyl methyl cellulose, starch acetate and glyceryl monostearate. The preparation method of the feed additive comprises the steps of preliminary mixing, coating material preparation and finished product feed additive preparation. The prepared feed additive is good in benzoic acid slow-release effect, excellent in antibacterial ability and capable of effectively inhibiting bacterial enteritis of poultry.
