Abstract

PROBLEM TO BE SOLVED: To make it possible to remove dire without using a detergent by foaming a melamine resin and forming a sponge cleaner as an elastic foaming body. SOLUTION: The sponge cleaner is formed as the open cellular body by foaming the melamine resin. The process for producing the melamine resin sponge produces an elastic foaming body mainly composed of the melamine resin by frothing an aqueous solution containing for example, a precondensate of melamine/formaldehyde, an emulsifier, a liquid foaming agent, a hardener and additives, then curing the foam. The sponge cleaner is the elastic foaming body consisting of the melamine resin as a base material and is, therefore, capable of chipping off the dirt sticking to a product without using the detergent and without flawing the product by the proper cushion property and hardness of the resin. The chipped off dirt enters the inside of the cells of the elastic foaming body and is, therefore, capable of preventing clogging.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sponge cleaner capable of removing dirt adhering to automobiles, furniture, household electric appliances, tableware and the like without using a detergent.

[0002]

2. Description of the Related Art Conventionally, sponge scourers are often made of foamed urethane resin to form a sea surface, and are commercially available of a type impregnated with an abrasive, or a layer formed by laminating hard fibers such as nylon, saran, and metal. .

[0003]

However, the sponge scourer based on the urethane resin removes dirt with a detergent, and when the dirt is severe and the dirt is removed with the hard fiber. May damage the target surface of dirt. In addition, there is a problem that the detergent is soaked in the cloth and discolored in the case of cloth furniture for applying the detergent. Furthermore, there is a problem that after the use of the detergent, wiping must always be performed with water, which is a very complicated operation. In view of the above, an object of the present invention is to provide a sponge cleaner capable of removing dirt without using a detergent in order to solve the above problems.

[0004]

According to the present invention, there is provided a sponge cleaner formed of an open cell by foaming a melamine resin in order to achieve the above object.

The method for producing a melamine resin sponge of the present invention includes, for example, a pre-condensate of melamine / formaldehyde,
An emulsifier, a liquid foaming agent and a curing agent, optionally bubbling an aqueous solution containing a conventional additive, and then curing the foam to produce an elastic foam mainly composed of a melamine resin. 0.2 to 4% by weight of an alkali salt of an organic acid, polyphosphoric acid or boric acid,
An alkaline earth salt or aluminum salt aqueous solution is added.

[0006]

The sponge cleaner of the present invention is an open-cell foam based on a melamine resin, so that it has a moderate cushioning property and resin hardness without using a detergent and without damaging the product. , Can remove the adhered dirt, the dirt that has been scraped, enters into the bubbles of open cells,
Prevent clogging. After use, dirt is washed away by washing with water and can be used repeatedly. Furthermore, by using the hydrated material, slippage is improved and workability is improved. Since the sponge cleaner of the present invention has the above characteristics, it is suitable for removing stains from tableware such as pottery, glass, metal, and plastic, bathtubs, electric appliances, lighting fixtures, furniture, and automobiles.
