Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

Abrasives used for buffing in metalworking use solids called blue bars, white bars, etc., which are related to the improvement of the washability of products after polishing. It is.

[0002]

2. Description of the Related Art Conventional solid abrasives have used abrasive powders and fats and oils such as paraffins and fatty acids. However, in many cases, it is difficult to clean the product which has adhered to the metal surface as buffing after use. As a washing method, an aqueous solution in which a surfactant is dissolved is used at a high temperature, or washing is performed with a harmful organic solvent or the like, but it is inefficient.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to improve a conventional abrasive which produces a buff residue which is difficult to clean and to obtain a solid abrasive which produces a buff residue which is easy to clean.

[0004]

Means for Solving the Problems Conventionally, water-insoluble fats and oils are used as a binder for an abrasive, but the present invention is water-soluble and has physical properties similar to conventional ones. The goal was to find one that was safe in terms of health and safety and pollution. As a result of examining various kinds of surfactants, the inventors have found that the problem can be solved by selecting and using water-soluble surfactants having a melting point of 30 ° C. to 160 ° C.

[0005]

The solid abrasive produced by using such a binder has the same usability as that of the conventional one when polishing, and the buff residue cleaning is sufficient by immersing it in water at room temperature or by giving vibration. Can be done.

EXAMPLE (1) 800 g of chromium oxide powder for polishing and 200 g of polyethylene glycol (an example of polyalkylene glycol) were put in a stainless steel beaker and heated with stirring to form a paste as a whole. This was poured into a container made of aluminum, cooled, and then taken out to obtain a solid abrasive. The stainless steel material was polished using this, and then cleaned, but the polishing condition was the same as that of the conventional product, and the cleaning property was easily performed with room temperature water. (2) In a stainless steel beaker, 700 g of aluminum oxide powder for polishing, polyoxyethylene polyoxypropylene glycol ether (an example of a water-soluble surfactant) 3
When 00 g is added and heated with stirring, the whole becomes a paste state. This was poured into a container made of aluminum, cooled, and then taken out and tested. The polishing condition was the same as that of the conventional product, and the cleaning property was easily performed with normal temperature water. (3) Chrome oxide powder 8 for polishing in stainless steel beaker
When 100 g of polyoxyethylene fatty acid ester (an example of a water-soluble surfactant) and 100 g of polyethylene glycol are added and heated with stirring, the whole becomes a paste state. This was poured into an aluminum container, cooled, and then taken out and tested. The polishing condition was the same as the conventional one, and the cleanability was easily performed with normal temperature water. (4) 700 g of aluminum oxide powder for polishing and 300 g of polyoxyethylene alkyl ether phosphate (an example of a water-soluble surfactant) are placed in a stainless steel beaker and heated while stirring to form a paste state. This was poured into an aluminum container, taken out after cooling, and tested. The polishing condition was the same as the conventional one, and the cleanability was easily performed with normal temperature water. (5) Chromium oxide powder 8 for polishing in stainless steel beaker
When 00 g and 200 g of polyoxyethylene alkylphenol ether (an example of a water-soluble surfactant) are added and heated while stirring, the whole becomes a paste state. This was poured into an aluminum container, taken out after cooling, and tested. The polishing condition was the same as the conventional one, and the cleanability was easily performed with normal temperature water. (6) In a stainless steel beaker, 700 g of aluminum oxide powder for polishing, polyoxyethylene polyoxypropylene block polymer (an example of a water-soluble surfactant) 30
When 0 g is added and heated while stirring, the whole becomes a paste state. This was poured into an aluminum container, taken out after cooling, and tested. The polishing condition was the same as the conventional one, and the cleanability was easily performed with normal temperature water.

[0007]

According to the present invention, buffing cleaning after polishing, which has hitherto been a difficulty in buffing using a solid abrasive, can be performed with water, which makes buffing cleaning safe, sanitary, and pollution-free. It is excellent in that it is low and the work is efficient.
