【発明の詳細な説明】 （産業上の利用分野） 本発明はホウロウ浴槽の補修方法に関するものである。[Detailed description of the invention] (Industrial application field) The present invention relates to a method for repairing an enameled bathtub.
（従来技術とその問題点）
従来、ホウロウ浴槽の補修方法として、表面が荒れたり
、キズついたりしたホウロウ破損部をエポキシ樹脂パテ
で埋めて補修する方法が採用されているが、部分補修で
あるため、パテの色合わせを入念に行っても補修部分と
補修しない部分の色違いがはっきりと識別され、また、
補修彎の風呂水との浸漬を繰り返すことによってホウロ
ウとパテとの接着度が低下し、パテが剥離するという問
題点がある。そのため、ホウロウ浴槽全面に均一に塗料
を塗布する方法が採用されるが、色むらの点は解消され
るものの、塗膜剥離の問題は依然解消されない。(Prior art and its problems) Conventionally, the method of repairing enamel bathtubs has been to fill in the damaged parts of the enamel, where the surface is rough or scratched, with epoxy resin putty, but this is only a partial repair. Therefore, even if you carefully match the putty colors, the difference in color between the repaired area and the unrepaired area can be clearly distinguished, and
There is a problem in that repeated immersion of the repair curvature in bath water reduces the degree of adhesion between the enamel and the putty, causing the putty to peel off. Therefore, a method is adopted in which paint is applied uniformly over the entire surface of the enamel bathtub, but although this solves the problem of uneven color, the problem of paint peeling still remains.
そこで、本出願人はフッ化水素を主成分とするエツチン

。Therefore, the applicant roughened the enamel surface with an etching solution containing hydrogen fluoride as a main component, filled in the scratches with epoxy resin putty if necessary, and then applied a solution prepared by diluting a silane coupling agent with an organic solvent to the substrate. We have proposed a repair method that involves sequentially applying an epoxy resin as a base coat and then applying an epoxy resin as a base coat (Japanese Patent Application No. 52,820/1982).
. However, surface treatment with etching liquid is dangerous because it uses powerful chemicals, and after the surface treatment, many work steps are required including base coating, base coat treatment, and top coat treatment, making repair work complicated. Moreover, this has led to the problem of high work costs.

そこで、本発明はエツチング液という劇薬を使用せず、

とを要旨とするホウロウ浴槽の補修方法にある。(Means for Solving the Problems) The present invention uses a bisphenol-based epoxy resin as the epoxy resin used as an undercoat, and mixes an aminosilane-based coupling agent into the curing agent. This was developed based on the fact that it is possible to perform a repair treatment with sufficiently high adhesive strength without pre-treatment of the base, and involves a sanding process to remove deteriorated areas on the surface of the enamel bathtub, and 100 parts by weight of the resin in a solvent. The aminosilane coupling agent is added to the curing agent diluted with 7.5 to 7.5% of the above resin content.
30 parts by weight is diluted with a solvent and mixed in, and then the curing agent mixture is mixed with bisphenol-based epoxy resin, and an undercoating process in which this is applied as a paint, and a topcoating process in which a urethane resin paint is applied are sequentially performed. The main point is how to repair an enameled bathtub.

である。On the other hand, it has been found that aminosilane coupling agents are particularly effective as silane coupling agents to be mixed into the curing agent, such as 3-aminopropylethoxysilane, 3-aminopropyl-triethoxysilane, etc. Silane, 3-aminopropyl-methyl-jethoxysilane, 3-aminopropyltrimethoxysilane, 3

である。The blending ratio of the aminosilane coupling agent to the above curing agent is usually 7.5 to 30 parts by weight of the aminosilane coupling agent other than the solvent per 100 parts by weight of the curing agent resin. If it is less than 7.5 parts by weight, the adhesive strength between the bisphenol-based epoxy resin and the enamel bathtub surface will not be sufficient;
This is because even if the amount exceeds 30 parts by weight, no improvement in adhesive strength will be observed and the epoxy resin will not be sufficiently cured.

業工数を減らせることができる。(Effects of the Invention) As is clear from the above description, according to the present invention, an aminosilane cup is used to make an old enamel bathtub look like new without causing scratches or discoloration. Since we use an undercoating process in which a curing agent mixed with a ring agent is mixed with bisphenol-based epoxy resin and applied as a paint, it is possible to remove deteriorated parts of enamel without using dangerous hydrogen fluoride in the sanding process. This allows for easy and sufficient surface treatment, and since there is no need to perform surface treatment before base coating, the number of work steps can be reduced.
