Embodiment 1

[0027] Preparation of Preliminary Example 1 High Purity Montmorillonite

[0028] 1. After the montmorillonite raw ore is crushed, take 50g sample and add 1L water (5% slurry concentration), mechanically stir for 15min, let it stand for 2min, and extract the supernatant by siphon method;

[0029] 2. Discard the coarse slag (impurities insoluble in water), add 4% sodium pyrophosphate dispersant (promote dispersion and suspension) to the upper liquid, stir, and draw out the upper slurry after standing and settling, and discard the middle slag;

[0030] 3. Centrifuge the upper slurry at high speed for 10 minutes, dry the upper high-purity slurry, and obtain high-purity montmorillonite after crushing.

Embodiment 2

[0031] Preliminary Example 2 Preparation of High Purity Attapulgite

[0032] 1. After the attapulgite raw ore is crushed, take 50g sample and add 1L water (5% pulp concentration), stir mechanically for 15min, let it stand for 2min, and extract the supernatant by siphon method;

[0033] 2. Discard the coarse slag (impurities insoluble in water), add 4% sodium pyrophosphate dispersant (promote dispersion and suspension) to the upper liquid, stir for a certain period of time, take out the upper slurry after standing and settling, and discard the middle slag;

[0034] 3. Centrifuge the upper slurry at high speed for 10 minutes, dry the upper high-purity slurry, and obtain high-purity attapulgite after crushing.

[0035] The preparation of embodiment 1 mineral complex

[0036] Get the high-purity montmorillonite and attapulgite prepared in preliminary examples 1 and 2, and make the two into suspensions with a concentration of 2% (g / ml) respectively, after soaking for 2 hours, acco...

Embodiment 3

[0039] Example 3 Preparation of mineral complex

[0040]Get the high-purity montmorillonite and attapulgite prepared in preparatory examples 1 and 2, and make the two into suspensions with a concentration of 10% (g / ml) respectively. After soaking for 2 hours, follow the montmorillonite: attapulgite= The two suspensions were mixed at a mass ratio of 9:1, stirred magnetically for 2 hours, centrifuged at 2000 r / min for 10 minutes, dried, and the prepared compound was passed through a 200-mesh sieve to obtain the product.

Abstract

The invention discloses a mineral composite capable of removing mycotoxin as well as a preparation method and application thereof. In the preparation method, by utilizing the characteristics of stable structure, strong adsorption and the like of high-purity montmorillonite and attapulgite, and the high-purity montmorillonite and the attapulgite are mixed in an aqueous solution and stirred, interact and intercalate to obtain the mineral composite. The mineral composite can be used for effectively removing the mycotoxin in a feed, and especially has a cooperative and synergistic adsorption effect on T-2 toxin. The mineral composite can be used as a mildew removing agent or feed additive, and the dosage of the mineral composite in the feed can be 0.3-1.5wt%; and the mineral composite can effectively adsorb various mycotoxins in the feed, and has the functions of improving the feed conversion rate, reducing the feed cost, reducing diarrhea and the like.

Description

technical field [0001] The present invention relates to a mineral compound, in particular to a mineral compound capable of effectively adsorbing mycotoxins and a preparation method thereof. The present invention also relates to the application of the mineral compound as a mildew remover or feed additive, belonging to the field of mineral compounds . Background technique [0002] Montmorillonite, also known as bentonite, is a silicate with a layered chain structure, which has various properties such as thixotropy, adsorption, and suspension. Attapulgite, also known as palygorskite, has an intermediate structure between a chain structure and a layered structure. Montmorillonite and attapulgite have been widely used in the feed industry. As feed additives, they can promote the metabolism of animal organisms, improve feed conversion rate, make animals have strong appetite, thick fur, fast weight gain, early slaughter, and reduce feeding costs. Montmorillonite and attapulgite a...
