Easily-degradable ceramic materials and manufacturing method thereof

Abstract

The invention is about a sort of one-off ceramic material. Which is easily degraded. It is made of major material degraded easily, binding admixture, the substance to puff, elasticizer, anti-friction material and water. The major material degraded easily is kaolin clay. The binding admixture is the mixture of innocuous organic and inorganic binding admixture. And the substance to puff is one or two of plant fiber, pearlstone and flotaftion bead. The elasticizer is plant fiber or glass fiber. The lubricant can be selected from plant oil, silicon oil, liquid wax, and polyglycol. The composition is proportioned by degratable major material 20-60%, binding admixture 20-35%, expanding agent 4-42%, toughness enhancing agent 5-10%, lubricant 1-3% and water 10-35%. It can be used for lableware, package lining, and flower pot, etc.

Description

technical field [0001] The invention relates to a degradable material, in particular to a disposable easily degradable ceramic material. Background technique [0002] Since foamed EPS was banned as a material for disposable tableware, various new materials have come out one after another, mainly in the following categories: 1. Paper and paper fiber materials; 2. Plant fiber materials; 3. Degradable plastics; 4. Starch materials; 5. Silicon-calcium composite degradable materials; all of the above materials have defects: paper and paper fiber materials not only consume valuable forest resources, but also generate a large amount of waste water, adding secondary pollution; plant fiber materials organic solubles Many, disposable tableware may produce peculiar smell, and easy to mildew, resulting in secondary pollution, the material itself is a flammable substance, high storage requirements; degradable plastic is not really degradable, when the molecular weight is greater than 200...

[0002] Since foamed EPS was banned as a material for disposable tableware, various new materials have come out one after another, mainly in the following categories: 1. Paper and paper fiber materials; 2. Plant fiber materials; 3. Degradable plastics; 4. Starch materials; 5. Silicon-calcium composite degradable materials; all of the above materials have defects: paper and paper fiber materials not only consume valuable forest resources, but also generate a large amount of waste water, adding secondary pollution; plant fiber materials organic solubles Many, disposable tableware may produce peculiar smell, and easy to mildew, resulting in secondary pollution, the material itself is a flammable substance, high storage requirements; degradable plastic is not really degradable, when the molecular weight is greater than 20000 At the same time, its half-life will be about 100 years; starchy materials are easy to mildew, difficult to store, and consume valuable food resources; silicon-calcium composite degradable materials contain Ca(OH) 2 Alkaline substances such as alkaline substances, buried in the ground will destroy the pH value of the original soil, and it is easy to burn the operator and damage the mold during the production process.

This patent has the following defects: the pH value of the soil is affected when the main material is degraded, the high price of hydroxyethyl cellulose makes it difficult to popularize and apply the high cost of the product, the color of expanded perlite is deep, and whitening agents must be used, and the strength of the finished product must be strengthened
