塗料組成物に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a novel coating composition. More specifically, the present invention provides a novel coating composition that can be used for coating objects made of synthetic resins such as melamine resin or phenolic resin, and for impregnating wood, paper, etc. for waterproofing, stain resistance, and anticorrosion. It is about things.

めのコーテイングを行なつている。[Prior Art] In a conventional method for manufacturing a patterned container made of synthetic resin, the basic form of the container is usually formed in the first molding, and then paper is attached using printed impregnated paper in the second molding. Furthermore, in the third molding process, a coating is applied to protect the paper pattern and other parts applied in the previous process.

が特に汚損され易いという欠点があつた。[Problems to be Solved by the Invention] For example, in the case of tableware made of melamine resin or phenolic resin, coating has traditionally been performed using a molding machine, which makes the coating process difficult and makes the tableware difficult to coat. Coating may not be possible depending on the shape. Further, it was impossible to coat the coating layer over and over again until the desired thickness was achieved. Furthermore, in the conventional method, the burr surface cannot be coated, so the burr surface is particularly susceptible to staining.
本発明は、これらの問題点を解消することを目

ある。 The present invention aims to solve these problems. In other words, the present invention provides a coating composition suitable for coating objects without using a molding machine, and since a molding machine is not used, the composition can be coated over and over, or without burrs. It can also be applied to surfaces to significantly improve the stain resistance of utensils.
［問題点を解決するための手段］
本発明の塗料組成物は、下記の組成からなり、
硬化前は乳白色の一液組成物である。[Means for solving the problems] The coating composition of the present invention consists of the following composition,
Before hardening, it is a milky white one-component composition.
組成：
メラミン樹脂またはグアナミン樹脂10〜15重量部
乳 酸 20〜30重量部
ケイ酸ジルコニウム １〜 ３重量部
メタアクリル酸−２−ヒドロキシプロピルエステ
ル ２〜 ５重量部
エチレングリコール ５〜10重量部
上記の組成物において、メラミン樹脂またはグ

イングの固形部分を形成するもので、樹脂量が10
重量部より少ない場合には、被膜の硬度が著しく
低下し好ましくない。また上記樹脂が15重量部よ
りも多い場合には、樹脂が乳酸に溶解されず、過
剰分が固形状態で残存し塗料組成物が透明になら
ないのでやはり好ましくない。Composition: Melamine resin or guanamine resin 10 to 15 parts by weight Lactic acid 20 to 30 parts by weight Zirconium silicate 1 to 3 parts by weight Methacrylic acid-2-hydroxypropyl ester 2 to 5 parts by weight Ethylene glycol 5 to 10 parts by weight Above In the composition, melamine resin or guanamine resin can be used alone or in combination. These resins form the solid part of the coating and the amount of resin is 10
If the amount is less than 1 part by weight, the hardness of the coating will drop significantly, which is undesirable. Furthermore, if the amount of the resin is more than 15 parts by weight, the resin will not be dissolved in lactic acid and the excess will remain in a solid state, which is not preferable since the coating composition will not be transparent.
乳酸はメラミン樹脂またはグアナミン樹脂の溶
剤の役割を有し、その量が20重量部より少なくな
ると前記樹脂が完全に溶解されない。また、乳酸
が30重量部よりも多い場合には、塗料の粘着性が
低下するので好ましくない。 Lactic acid has the role of a solvent for melamine resin or guanamine resin, and if the amount is less than 20 parts by weight, the resin will not be completely dissolved. Furthermore, if the lactic acid content is more than 30 parts by weight, the adhesiveness of the paint decreases, which is not preferable.
ケイ酸ジルコニウムは、塗面の耐摩耗性を向上
させるために添加するものであり、ケイ酸ジルコ
ニウムの量が１重量部よりも少ないとその効果が
発揮されず、３重量部よりも多い場合には、耐摩
耗性は向上せず逆に塗面に亀裂が生じ易くなり、
また塗料の付着力が低下する。 Zirconium silicate is added to improve the abrasion resistance of the painted surface, and if the amount of zirconium silicate is less than 1 part by weight, the effect will not be exhibited, and if it is more than 3 parts by weight, does not improve wear resistance, but on the contrary, the painted surface is more likely to crack.
Also, the adhesion of the paint decreases.
メタアクリル酸−２−ヒドロキシプロピルエス
テルは塗面の硬度を高め、かつ光沢を与えるため
に添加するものであり、２重量部より少ないとこ
れらの性能の向上はさほど期待できず、また５重
量部よりも多いと塗布に際して液溜りや液垂れが
生じる。 Methacrylic acid-2-hydroxypropyl ester is added to increase the hardness and give gloss to the painted surface, and if it is less than 2 parts by weight, no significant improvement in these properties can be expected, and if it is less than 5 parts by weight, If the amount is more than that, pooling or dripping will occur during application.
更に、エチレングリコールは本発明の塗料組成

にいわゆる「はじき」を生ずるので、前記の範囲
が好適である。 Furthermore, ethylene glycol acts as a diluent in the coating composition of the present invention, and if its amount is less than 5 parts by weight, the phenomenon of viscosity (the coating increases in viscosity over time) occurs; If the amount exceeds 10 parts by weight, the paint will be repelled from the surface to be coated, causing so-called "repellency" in the paint film, so the above range is preferable.
上記塗料組成物は、次のような方法により使用
することができる。 The above coating composition can be used by the following method.
イ あらかじめ成形した器物の被塗布面の塵埃や
汚染などを取り除き清浄にした後、上記塗料組
成物を、、刷毛、スプレー、ウエスなどで塗布
しあるいは浸漬により塗布する。塗布に際して
は液溜りや液垂れができないように薄目に塗布
することが望ましい。(b) After the surface of the pre-formed utensil to be coated is cleaned by removing dust and contamination, the above-mentioned coating composition is applied with a brush, spray, rag, etc., or by dipping. When applying it, it is desirable to apply it thinly to avoid pooling or dripping.
ロ 厚塗りを施す場合は、１回塗布する毎に30分

食性を与えることができる。 In addition, when wood, paper, etc. are impregnated with the coating composition of the present invention, it may be dried at room temperature. By doing so, the coating composition of the present invention is filled into the gaps between the fibers of the wood or paper and cured, thereby imparting water resistance and anticorrosion properties.
また、本発明の塗料組成物は、硬化後に無色透
