Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sponge soap for cleaning the human body, clothing, utensils, etc. from contamination at low cost and efficiently.

The next day and day will be “trying.”

Traditionally, when cleaning contaminated objects on the human body, clothing, utensils, etc., cleaning agents such as soap or synthetic detergents are applied to a flexible substrate such as polyurethane foam, and then mechanical cleaning is performed. It has been common practice to increase efficiency and promote foaming, but in this case, a large amount of cleaning agent is wasted along with cleaning water, which is not only uneconomical, but also causes an increase in contaminated wastewater, which poses a problem of environmental pollution.

1' In order to solve the above-mentioned problem, the present invention uses a sponge soap made by impregnating and filling an open cell type synthetic resin foam with a known alkali soap, thereby preventing wastage of cleaning agent. At the same time, we provide a cleaning agent with high foaming efficiency and excellent cleaning efficiency that can be obtained at a low price, and in particular, it greatly contributes to the prevention of environmental pollution by keeping the degree of contamination of cleaning wastewater to less than half of the conventional level. be.

Shumi Mamezatateya The present invention comprises a porous foamed synthetic resin base consisting of a large number of continuous pores, a cleaning soap impregnated into the continuous pores, and, if desired, fragrances, dyes and other additives mixed with the soap. General synthetic resin foams are used as the porous synthetic resin base for sponge soaps, but in particular thermosetting resins, such as open cells of phenolic, melamine, urea, and alkyd polyester isocyanate resins, are used. Type foams can be used, and flexible polyurethane foams are particularly preferred for economic and purpose reasons.

In addition, soda soap is commonly used as a cleaning agent, and its hardness, cleaning power, and degree of foaming can be selected depending on the purpose.
By passing the foam substrate through a bare bath, the cleaning agent, usually in solid or greasy form, is impregnated into its continuous body. If desired, fragrances, dyes, and other additives suitable for the purpose can be added to the cleaning agent.

When using the sponge soap with the above structure,
The contaminated object can be easily separated from the object by soaking it lightly in water, applying an appropriate amount of water to the object, and then moving the wetted sponge soap into contact with the contaminated object to form foam. Separated contaminants can be easily removed from the contaminant by post-watering.

A sponge soap that is used once can be used many times until the filled soap body is completely consumed, making it economical.

Manufacturing example width 70cm, length 130cm+m, thickness 5cm density 50
A flexible open-cell polyurethane foam of g/33 is moved on a roller conveyor as a base, and 1 having the following composition is used.
A soap pot filled with liquid plain glue at 00℃ (length 1
．． 5ms width 90mm, depth 501mm) is supplied via a guide roller and a compression roller, and the first stage compression row arm has a thickness of 1cm.
The liquid soap was compressed to 3 cm using a second-stage compression roller and moved through the liquid soap bath at a speed of 60 (2) 7 minutes, and the liquid soap was sufficiently absorbed and impregnated into the continuous chest of the substrate. The material was pulled up by a guide row, transferred to a roller conveyor, and dried by passing through an infrared drying tunnel to obtain a soap-impregnated solid sponge board.

The solid sponge board thus obtained was 13 cm long and 8 cm wide.
The cake was cut into cakes with a size of 400g and a weight of 400g, and molded into a product.

Composition of a bare soap bath: Coconut oil-based soap glue 15 parts Caustic soda aqueous solution 75 parts Neutral fat 10 parts Example Using the sponge soap produced in the above manufacturing example, semi-coat it with a solvent of water and castor oil in a ratio of 8:1. 20g charcoal powder
It was possible to completely clean 60 1D contaminated cotton sheets that had been evenly contaminated with this method. The weight of soap consumed was 380g, and the total amount of washing waste water was 500j.

Using the same bare metal composition as in the above example, the length is 13c.
A soap cake with a width of 7 (2) and a thickness of 5 cm was molded. Its pure stone content weight was 430 gr.
The contaminated sheets No. 1-, which were prepared in the same manner as in Examples, were thoroughly washed, and the number of washed sheets was 38 until the soap cake was reduced to an unusable size. The total amount of washing wastewater is 8001
Met. Note that the ratio of foaming and carbonization between the comparison soap and the sponge soap according to the present invention was approximately 1:4.

Effects of the Invention By using the sponge soap of the present invention, the amounts of water and detergent required for complete cleaning of contaminants of the same degree of contamination can be reduced to approximately half of those of conventional products. This fact means that the amount of contaminated wastewater is halved, and the concentration of sulfur in the center of the wastewater is also about half, so the degree of contamination is actually A compared to when ordinary soap is used.
