Embodiment 1

[0017] Example 1 , Using eggshells as raw materials to prepare abrasives

[0018] The eggshell friction agent is prepared by using the eggshells of chicken eggs, duck eggs, goose eggs, pigeon eggs and quail eggs as raw materials respectively according to the following steps.

[0019] A. Wash and dry the eggshells, put them into a pulverizer to crush the eggshells, and obtain eggshell powder with a particle size of 150-250 mesh;

[0020] B. Put the obtained eggshell powder in a ball mill, adjust the specific gravity of the ball material, the size and quantity of the grinding medium as required, and control the speed to pulverize. After ball milling, ultrafine eggshell powder with an average particle size of 0.1-100 μm is obtained.

[0021] The superfine eggshell powder obtained above can be made into a friction agent without adding additives.

Embodiment 2

[0022] Example 2 , Composition determination of friction agent

[0023] Get the eggshell friction agent that embodiment 1 obtains and measure its composition, the result is as follows:

Embodiment 3

[0028] Example 3 , Eggshell friction agent is used in the production of daily chemical products

[0029] Get the eggshell friction agent that embodiment 1 obtains, adopt conventional method to produce toothpaste and skin cleanser respectively by following formula (note: the percentage in the following formula is weight percent).

[0030] 1. Toothpaste

[0031] Eggshell abrasive: Appropriate amount Preservative: 0-0.5%

[0032] Humectant: 15-50% Sweetener: 0-1.0%

[0033] Detergent: 0.5-2.5% Special additives: 1-2%

[0034] Thickener: 0.4~6.0% Flavor: 1~2%

[0035] Deionized water: balance.

[0036] The friction agent used to make toothpaste needs to be powdery solid, with fine particles and soft texture. Eggshell friction agent has obvious advantages in this respect.

[0037] 2. Skin cleanser

[0038] Eggshell friction agent: Appropriate amount Glycerin: 14.0%

[0039] Myristic Acid: 15.0% Potassium Hydroxide: 6.0%

Abstract

The invention discloses an application by adopting an eggshell to prepare a friction agent and a frication agent prepared by the eggshell thereof. By adopting the eggshell to prepare the friction agent, the invention not only effectively utilizes the eggshell, but also protects the health of gingival and oral mucosa when being used for cleaning teeth, for the friction agent produced by eggshell containing a large amount of trace elements and nutrition compositions that are beneficial to human health. At the same time, the invention is used for cleaning skin as cosmetics, so as to have excellent performances of moistening, enhancing skin elastic and luster, etc. Compared with the industrial material such as mineral deposit containing calcium, the eggshell is a pure natural biological material, which has the advantages of no heavy metal impurities containing such as mercury, lead and manganese, no stimulation, toxicity and side effect in human body, having high security and environment friendly. The invention has wide application prospect in the friction agent field.

Description

technical field [0001] The invention belongs to the field of daily chemicals, and in particular relates to a new application of using eggshells to prepare abrasives. Background technique [0002] In the field of daily chemicals, abrasives are widely used in toothpaste and other cleaning products, for example, in toothpaste, the content of abrasives accounts for about 25-60%. As a high-quality friction agent, it must have moderate particle size and hardness, that is, moderate friction, so that it can remove the dirt on the surface of the object without causing damage to the surface of the object and its surroundings. [0003] In the field of daily chemicals, the calcium-containing friction agents that are widely used mainly include: calcium hydrogen phosphate dihydrate, calcium hydrogen phosphate anhydrous, calcium pyrophosphate, tricalcium phosphate, insoluble sodium metaphosphate and calcium carbonate. [0004] The following is a performance comparison of the above calcium...
