Embodiment 1

[0021] A preparation process of organic attapulgite clay anti-caking agent, comprising the following steps:

[0022] (1) Take lightweight attapulgite clay, weather it for 5 months, and dry until the water content is less than 20%;

[0023] (2), crush the dried attapulgite clay with a crusher, and sieve to obtain fine soil with a particle size of 8-10mm;

[0024] (3) Put the crushed clay into the kiln and dry at 300°C until the moisture is less than 5%;

[0025] (4) Mix the dried clay and surfactant palm hydrogenated oil evenly in a ratio of 100:1 by weight;

[0026] (5) Use a grinding device to grind the clay treated in step (4) into a 400-mesh attapulgite powder, and pack it into bags.

Embodiment 2

[0028] A preparation process of organic attapulgite clay anti-caking agent, comprising the following steps:

[0029] (1) Take lightweight attapulgite clay, weather it for 6 months, and dry it until the water content is less than 20%;

[0030] (2), the dried attapulgite clay is crushed with a crusher, and sieved to obtain fine soil with a particle size of 10mm;

[0031] (3) Put the crushed clay into the kiln and dry at 300°C until the moisture is less than 5%;

[0032] (4) Mix the dried clay with palm hydrogenated oil, erucamide, and octadecyl primary amine in equal quantities, and mix them evenly at a weight ratio of 100:1;

[0033] (5) Use a grinding device to grind the clay treated in step (4) into a 400-mesh attapulgite powder, and pack it into bags.

Abstract

The invention belongs to the field of industrial additives and in particular relates to a process for manufacturing an organic attapulgite clay anti-blocking agent. The process comprises the steps of (1), weathering and drying light attapulgite clay; (2), breaking the dried attapulgite clay by using a breaker and sieving to obtain fine soil with a particle size of 8-10mm; (3), adding the broken clay into a kiln and drying at 280-350 DEG C till the content of water is less than 5%; (4), mixing the dried clay with a surfactant evenly according to a certain ratio; (5), grinding the processed clay in the step (4) into attapulgite powder with 300-500 meshes by using a grinding device, filling the attapulgite powder in bags and packaging. According to the process, the inorganic clay is used as the raw material, so that the process is extensive in source of raw materials, simple and free of toxic or side effect; the anti-blocking agent is good in anti-blocking effect; no pollutant is produced in the process of manufacturing.

Description

technical field [0001] The invention belongs to the field of industrial additives, and in particular relates to a production process of an organic attapulgite clay anti-caking agent. Background technique [0002] Attapulgite clay refers to a clay mineral with attapulgite as the main component. Attapulgite is a crystalline hydrated magnesium aluminum silicate mineral with a unique layer chain structure. There is a lattice replacement in its structure, and the crystal contains variable amounts of Na+, Ca2+, Fe3+, Al3+. It is needle-like, fibrous or fibrous aggregates. The anti-caking agent is mainly used to prevent the agglomeration of powdery or granular substances, and mainly uses the surface properties of the substance to prevent the agglomeration of the substance. The existing anti-caking agents are expensive, complicated in production process and often have certain toxicity. Contents of the invention [0003] In order to solve the above-mentioned shortcomings of the p...
