Abstract

The present invention relates to a fluororesin primer containing poly(ether-ketone-ketone) resin and a laminating body using the same, and belongs to the technical field of polymers. The fluororesin primer containing poly(ether-ketone-ketone) resin of the present invention is composed of the following substances in percentage by mass: 5-15% of poly(ether-ketone-ketone); 5-15% of polyethersulfone;20-35% of F40; 0.5-5% of surfactant; 1-5% of viscosity-increasing colloid; 5-15% of organic solvent; 0.5-1% of pigment; and the balance of water. The fluororesin primer containing poly(ether-ketone-ketone) resin has the characteristics of strong adhesion, good heat resistance and excellent chemical resistance. At the same time, the present invention also provides the laminating body using the same, and solves the problem that a conventional fluororesin anticorrosive coating has poor adhesion to a metal substrate and poor vacuum resistance.

Description

technical field [0001] The invention relates to a fluororesin primer containing polyether ketone ketone resin and a laminate using the same, belonging to the technical field of polymers. Background technique [0002] Polyether ketone ketone (PEKK), as a high-performance thermoplastic engineering plastic, has excellent heat resistance and excellent mechanical properties. At present, polyether ketone ketone is used as a coating, which has many excellent properties, such as excellent combination with the substrate, good chemical resistance, high temperature resistance and so on. At present, the polyethylene-tetrafluoroethylene copolymer (F40) is coated on the metal substrate, because the non-stickiness of the fluorine material itself leads to poor adhesion of the coating. The traditional fluororesin primer has a certain binding force to the coating, but the bonding is only limited to physical bonding. In a high vacuum state, problems such as coating peeling will occur. [000...
