Abstract

PURPOSE:To enable exact detection of the degree of corrosion inside a radiator from the color change of radiator cooling water by adding an aqueous soln. consisting of orthophenanthrone, org. solvent compatible with water and ascorbic acid of the specific ratio with respect to said three material to the cooling water. CONSTITUTION:A soln. consisting of 0.2-10pts.wt. org. solvent such as methanol, ketone, etc. compatible with water with respect to 1pt.wt. orthophenanthrone, 0.5-20pts.wt. ascorbic acid and water of the amt. enough to dissolve these materials is added to radiator cooling water for detecting the corrosion in the radiator. The effect of preventing corrosion of the radiator and the nonfreezing property of the cooling water can be obtd. by incorporating futher ethylene glycol and condensated sodium phosphate respectively at 1-10wt% and 10-50wt% by the total weight of the compsn. thereto. If such detecting liquid is added at 10- 1,000ml to the cooling water, the cooling water discolors quickly when corrosion is high. Even if the cooling water is colored red or green, the cooling water discolors to a brown color and therefore the corrosion is distinctly detected.

Description

【発明の詳細な説明】 −内部の腐蝕検出用に用いられろ組成物に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION - A composition for use in internal corrosion detection.

ラジェーター特に自動車のラフエータ−には、冷却媒体
として水が入れられるがこのためラジェーター内部が錆
びやすくなる。Water is used as a cooling medium in radiators, particularly in automobile luffers, but this makes the interior of the radiator susceptible to rust.

しかしラジェーター内部を直接観察することは出来ない
ので、ラジェーター内部の腐蝕状態を簡便に知ることが
できる手段が従来から望まれていた。However, since it is not possible to directly observe the inside of the radiator, there has been a desire for a means to easily determine the corrosion state inside the radiator.

本発明は上記の課題を解決し得るランエータ−内部の腐

ター内部の腐蝕検出用組成物である。This composition is added to the radiator cooling water, and its color change indicates the progress of corrosion. That is, the object of the present invention is 1 part by weight of orthophenanthroline, 0.2 to 10 parts by weight of a water-compatible organic solvent, 0.5 to 10 parts by weight of an organic solvent compatible with water,
A composition for detecting corrosion inside a radiator, comprising 20 parts by weight of 7-scorhinic acid and at least an amount of water sufficient to dissolve them.

ても特段の利点がなく、コスト及び取扱いやすさの点か
らより多量に含まれることは望ましくない。Methyl ketone and methyl ether are used. Such water-compatible organic solvents include orthophenanth. It helps phosphorus dissolve stably in water and is essential for producing the discoloration reaction that indicates corrosion with good reproducibility. The organic solvent is
It should be contained in an amount of 0.2 to 10 parts by weight per 1 part by weight of orthophenanthroline. If the amount is less than 0.2 parts by weight, sufficient discoloration cannot be obtained. On the other hand, there is no particular advantage if more than 10 important parts are included, and it is not desirable to include more than 10 important parts from the viewpoint of cost and ease of handling.

アスコルビン酸は、オルトフェナンスロリン１重量部当
り０５〜２０重量部含まれなければならない。０５重量
部より少いと、変色反応が十分でなく。Ascorbic acid should be contained in an amount of 05 to 20 parts by weight per 1 part by weight of orthophenanthroline. If the amount is less than 0.5 parts by weight, the color change reaction will not be sufficient.

一方２０重量部より多く含めることはコストが高くなり
好ましくない。On the other hand, it is not preferable to include more than 20 parts by weight because it increases the cost.

This not only provides a rust preventive effect on the radiator and antifreeze properties to the cooling water, but also increases the stability of the color change reaction of the present invention.

The red color is due to the addition of Alamance (color change No. 2), and the green color is due to the addition of soap green. If the composition of the present invention is used in cases where the coolant has these colors, the red or green color of the coolant will first disappear, and then, if there is corrosion, it will take on a brownish color. Therefore, the composition of the present invention exhibits excellent effects when used in conventional automobile radiators.
