Background

At present, the external structure of many products, especially the electric products, is complex, and the cleaning products can not be cleaned in a large area by water, so the cleaning glue which can be kneaded into various shapes is put into the market and widely applied.

The cleaning glue is mainly used for cleaning dead corners of various objects, such as computer keyboards, automobile inner chambers, shoes and electric appliances with complex outer structures, and is very high in applicability especially for electric appliance products with densely arranged keys.

Although the existing cleaning glue can be kneaded into various shapes and has strong dust and powder sticking capacity, the existing cleaning glue still has many defects which are mainly expressed in that:

1) the cleaning glue has complex and unsafe components, and partial cleaning glue has fading condition;

2) the cleaning glue needs to be heated for production, so that the cost is high;

3) the existing cleaning glue has weak cleaning capability on dirt adhered on the outer surface of an electric appliance, has larger elasticity and poorer permeability;

4) the chemical property is unstable, especially the acid and alkali resistance, the oxidation reduction resistance and the light and heat resistance are poor, so that the storage life of the product is not long at the normal temperature of 10-25 ℃, generally 6-8 months, and the service life is shorter.

In addition, the existing cleaning glue is prepared by combining phthalate and the like serving as softening agents and polyvinyl alcohol, has toxicity, and is very harmful to human bodies after being operated by naked hands for many times during cleaning; in terms of color, the existing cleaning glue is mainly divided into red, yellow and blue, wherein the color has a very great effect on the cleaning glue, and is mainly used as the bottom color of the cleaning glue to easily see the dirt and dust particles to be cleaned.

The existing cleaning glue is mostly used with industrial pigments, and the cleaning glue is easy to change color after being used for many times, is relatively unsafe, and is easy to turn into black to be used after being used for cleaning the metal surface.
