Acid-treated attapulgite padding and preparation method thereof

Abstract

The invention discloses an acid-treated attapulgite padding and a preparation method thereof, and relates to the technical field of animal tools. The padding comprises the following raw materials in parts by weight: 350-450 parts of acid-treated attapulgite, 15-25 parts of starch, 1-5 parts of a preservative and 180-220 parts of water. The acid-treated attapulgite padding is rod-shaped, has the length of 5-20 mm and the width of 0.3 mm, has natural moisture of less than or equal to 5%, is uniform and consistent in color, has no obvious color difference, no pungent smell and no mildew smell, has certain water absorption capacity, thermal insulation performance, bacteriostasis and odor removal functions, and is high in hardness and non-toxic. The attapulgite is modified by adopting 2 mol / L industrial sulfuric acid, and the acid treatment result increases the specific surface area and water absorption performance of the attapulgite. Mouse feeding experiments prove that compared with traditional padding, the padding has lower replacement frequency and remarkably reduced use cost. The padding disclosed by the invention takes the acid-treated attapulgite as a main component, and is simple in manufacturing process, low in cost and easy to popularize and use.

Description

technical field

[0001] The invention belongs to the technical field of animal utensils, and in particular relates to a litter with attapulgite treated with 2mol / L industrial sulfuric acid as a main raw material and a preparation method thereof. Background technique

[0002] Attapulgite clay is a magnesium-aluminum-rich silicate mineral, which is earthy and dense and occurs in sedimentary rocks and weathered crusts, and its color is white, blue-gray, brick red, etc. Its relative density is about 1.6, it is not easy to disperse when it is wet, and it has viscosity and plasticity; it shrinks little when dry and does not produce cracks; it has strong water absorption. The pH is about 8.5, and there are many internal crystal channels, so the specific surface area is very large, up to 350m per gram 2 above. Attapulgite deposits with industrial significance are mainly distributed in a few countries such as the United States, China, and Spain, and there are very rich attapulgite m...

[0036] One of the preparation methods of embodiment 1 acid treatment attapulgite pad

[0037] The acid-treated attapulgite litter is prepared from the following raw materials in parts by weight: 400 parts of acid-treated attapulgite, 25 parts of corn starch, 3 parts of potassium sorbate, and 200 parts of water.

[0038] The acid-treated attapulgite gasket comprises the following steps:

[0039] (1) Pulverize the attapulgite and pass through a 200 mesh sieve, then modify it with 2mol / L industrial sulfuric acid, the solid-liquid ratio is 1:10, stir the mixed solution on a magnetic stirrer for half an hour, and let it stand at room temperature Set aside for 24 hours, add distilled water to wash to remove excess sulfuric acid, filter with a vacuum pump, dry in a blast drying oven, then continue to crush and pass through a 200-mesh sieve, and store for future use.

[0040] (2) Weigh 400 parts of acid-treated attapulgite and 3 parts of potassium sorbate, and mix them uniformly.

[0056] Example 3 Key Index Evaluation Method of Acid Treatment Attapulgite Pad

[0057] Evaluation method of sensory indicators: Place the litter sample in a white tray, in an environment without direct sunlight, sufficient light, and no peculiar smell, check the color, mildew and impurities with eyes, and check the smell with nose.

[0058] figure 2 It is acid-treated attapulgite litter. It can be seen from the figure that the litter has uniform color, no obvious color difference, and no foreign impurities visible to the naked eye. The detection of its smell with the method of sniffing, finds that this litter has no irritating smell, also has no moldy smell.
