発明の技術分野
本発明は、有機溶剤に溶解して常温で速やかに硬化させ
ることができ、しかも基材との密着性に優れた含フッ素
共重合体およびその用途に関する。DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a fluorine-containing copolymer that can be dissolved in an organic solvent and rapidly cured at room temperature and has excellent adhesion to a substrate, and uses thereof. .
発明の技術的背景ならびにその問題点
建築物、車輌、船舶、航空機等の外装分野には耐候性、
耐久性の優れた塗料が要求され、ポリエステル系または
アクリル系の高級外装塗料が利用されている。しかし、
既存塗料の屋外耐用年数は短く、上述の高級塗料でさえ
数年で美観と基材保護作用を失ってしまう。Technical background of the invention and its problems Weather resistance,
Paints with excellent durability are required, and high-grade exterior paints based on polyester or acrylic are used. but,
Existing paints have a short outdoor service life, and even the above-mentioned high-quality paints lose their aesthetic appearance and substrate protection effect within a few years.

発が試みられている。On the other hand, fluoropolymers are extremely stable both thermally and chemically, and have excellent weather resistance, water resistance, chemical resistance, solvent resistance, mold releasability, low friction, and water repellency. Suitable as a surface treatment agent for various substrates. However, conventionally known fluoropolymers suffer from the above-mentioned properties,
It was difficult to form a coating film because it was soluble in organic solvents, making it extremely difficult to use it as a paint. For example, currently known paints made from fluorine-based polymers are mostly powder paints, with only a small amount of PVdF (polyvinylidene fluoride).
It is simply used as an organic solvent-dispersed paint by taking advantage of its ability to dissolve in specific solvents at high temperatures. Moreover, since these fluoropolymer paints require baking at high temperatures to form a film, their field of use has been limited to areas where heating equipment is available. In addition, the need for heating equipment and the baking process are
This is not desirable from the viewpoint of the safety of the people involved in the work and the environment of the workplace. Therefore, in recent years, attempts have been made to develop fluoropolymers that are solvent-soluble or do not require a baking process at high temperatures.

あり、有機溶剤には実質的に不溶である。For example, JP-A-57-34107 discloses a quaternary copolymer consisting of fluoroolefins, cyclohexyl vinyl ethers, alkyl vinyl ethers, and hydroxyalkyl vinyl ethers, and this copolymer is soluble in organic solvents. It is also described that it can be cured at room temperature. However, in order to cure this copolymer at room temperature, a melamine-based curing agent or a urea resin-based curing agent is required, and as a matter of course, it is used in a two-component type, which is poor in workability. Further, the glass transition temperature of this copolymer is relatively high, at or above room temperature, that is, at or above 25°C. Furthermore, although no actual example is described in Japanese Patent Publication No. 46-39472, an organosilicon compound having an olefinic unsaturated bond and a hydrolyzable group is added to PTFE (polytetrafluoroethylene) using an organic hydroperoxide. It has been suggested that those mechanically treated in the presence of a radical initiator such as the above are crosslinked and cured by water at room temperature. However, the fluoropolymer produced by this method is a polymer in which an organosilicon compound is grafted onto PTFH, and is substantially insoluble in organic solvents.
