Description

  The present invention relates to a dryer which is a drying accelerator for a paint using an oxidation polymerization type resin, and a paint using the dryer.

  A drying accelerator (dryer) for drying the paint is added to the paint containing the oxidation polymerization type resin. The dryer used is generally a metal salt of a heavy metal such as cobalt, manganese, lead, iron or zinc and various carboxylic acids (hereinafter sometimes abbreviated as “metal soap”). Among these metal soaps, cobalt metal soap has been used as a main dryer so far because of its excellent drying performance.

  Cobalt metal soap has excellent drying performance, but is listed in Group 2B, which is listed as “suspected to be carcinogenic to humans” in the list of carcinogenic risks of the International Cancer Institute. There is a point that there is a concern, the supply of metal cobalt is unstable because it is a rare metal, the cost of cobalt metal soap is expensive, etc., while reducing the amount of cobalt metal soap used, it is high There has been a demand for a dryer having curing performance.

  Therefore, in order to achieve a smaller amount of cobalt metal soap used, cobalt metal soap, manganese metal soap, and at least one amino alcohol selected from diethanolamine, diethylethanolamine, dibutylethanolamine, and n-butyldiethanolamine are contained. The dryer which performs is proposed (for example, refer patent document 1). However, since cobalt metal soap is still used, it has not solved the above-mentioned carcinogenic concerns, raw material supply anxiety and high cost problems.

  As a dryer that does not use cobalt metal, a dryer using manganese soap and bipyridyl in combination has already been proposed before the disclosure of Patent Document 1 (see, for example, Patent Document 2).

  In general, when a paint is applied, in order to prevent the occurrence of uneven coating, it is common practice to repeatedly apply a paint having a low concentration of coating film forming components. When overcoating, wrinkles and shrinkage occur in the coated film unless the coating interval is left. For this reason, the paint including the dryer disclosed in Patent Document 1 and Patent Document 2 has to have an interval of about one day when it is repeatedly applied, which has a problem of poor coating efficiency. There is also a problem that the gloss of the coating surface is not sufficient.
