Embodiment 1

[0053] Raw materials: Diatomite comes from the Liudaogou mining area in Linjiang, Jilin Province, and its main chemical composition and content are SiO 2 : 63.77%, Al 2 o 3 : 18.97%, Fe 2 o 3 : 1.48%, TiO 2 : 0.06%, CaO: 0.48%, K 2 O: 0.16%, Na 2 O: 0.04%. Aluminum hydroxide is analytically pure, white powder with the chemical formula Al(OH) 3 . Copper chloride dihydrate is analytically pure, green powder, chemical formula is CuCl 2 ·H 2 O.

[0054] The preparation process steps are as follows:

[0055] (1) Weigh 12.84g of sodium hydroxide and dissolve it in 115.6mL of distilled water, respectively take 10.07g of diatomite ore sample and 4.50g of aluminum hydroxide and join in the above-mentioned sodium hydroxide solution, and age with magnetic stirring for 30min to make Diatomaceous earth and aluminum hydroxide are fully dispersed in sodium hydroxide solution to form silica-alumina sol.

[0056] (2) Add the suspension obtained in step (1) into a 150.0 mL hydrothe...

Embodiment 2

[0060] The raw materials and steps are the same as in Example 1, except that 12.89g of sodium hydroxide is dissolved in 116.0mL of distilled water, and 10.83g of diatomite ore samples and 4.84g of aluminum hydroxide are added to the above-mentioned sodium hydroxide solution middle. Hydrothermal reaction at 110 ° C for 5h.

Embodiment 3

[0062] Same as the raw materials and steps in Example 1, the difference is: 13.20g sodium hydroxide is dissolved in 119.0mL distilled water, 5.17g of diatomite ore samples and 2.31g of aluminum hydroxide are added to the above-mentioned sodium hydroxide solution middle. Hydrothermal reaction at 110 ° C for 5h.

Abstract

The invention provides a feed antibacterial agent containing a copper-carrying X-type molecular sieve and a preparation method of the feed antibacterial agent. Aiming at the defects of the traditionalmethod for preparing the X-type molecular sieve material at present, the invention provides a method for synthesizing the X-type molecular sieve from diatomite as a silicon source and part of aluminum source with a hydrothermal method; a copper-carrying molecular sieve antibacterial material is further prepared from the X-type molecular sieve as a carrier with an ion exchange method, and accordingly, antibiotics in feed are replaced. Harm of the antibiotics to people and animals is greatly reduced. The antibacterial agent has obvious advantages in preparation cost, product performance, process flow, environmental friendliness, cost performance and the like; the raw materials are from natural minerals, thereby being richly sourced and low in cost; the synthesis process is green and environmentally friendly, the equipment requirement is low, the product performance is high, and industrial production potential is achieved.

Description

technical field [0001] The present invention relates to the technical field of antibacterial agents for feed, in particular to an X-type molecular sieve copper-loaded antibacterial agent for feed and a preparation method thereof Background technique [0002] The diarrheal disease of animal pups caused by Escherichia coli is the main cause of its low survival rate, and the current solution is to add antibiotics to the feed. However, with the increase of drug resistance of pathogenic bacteria, the extensive use of antibiotics will inevitably produce resistance and residues in the environment, seriously endangering the health of humans and animals. Therefore, finding ways to reduce the amount of antibiotics or alternatives to antibiotics has become a research focus in various countries. In order to achieve the purpose of antibacterial and sterilizing, domestic and foreign efforts are made to load antibacterial substances on various adsorbent materials to make them have antibact...
