Description
Technical field
The present invention relates to a kind of organic coating composition, more particularly, the present invention relates to a kind of non-sticky metallic coating composition that has wear resisting property and antiseptic property for the metallic surface.
Background technology
Non-viscous paint has advantages of low surface energy and high heat resistance, mainly is coated on the metallic surfaces such as aluminium, cast iron, stainless steel, plays protection, decoration, the function affect such as heat-resisting, not sticking, easy clean.The temperature of non-viscous paint life-time service is between 180 ℃～250 ℃, thereby selected resin should have, and strong adhesion, Good Heat-resistance, hardness are high, the characteristics of good mechanical property.
The exploitation of non-viscous paint has had the history in more than 30 years so far, although developed multiple coating for applying non-sticky metallic coating over more than 30 year, its main component mostly is still tetrafluoroethylene (PTFE) and is the macromolecular material of main component.
Tetrafluoroethylene is the perfluoro polymkeric substance that is formed by the tetrafluoroethylene copolymerization.It is high that tetrafluoroethylene has degree of crystallinity, molecular weight is large, does not have side chain in the molecule, fluorine atom closely be arranged in the C-C skeleton around, C-F bond energy height and fluorine atom play the constructional features such as shielding effect to main chain, it is little that these characteristics have determined that it has a frictional coefficient, do not absorb water, sticking, do not fire, weathering resistance is good, and the characteristics such as use temperature wide ranges and dielectric properties excellence are so that fluorine coating has possessed the good characteristic that other coating does not possess.But tetrafluoroethylene is expensive, and strict to the processing requirements of ground when having construction, poor processability, melt temperature is high and be insoluble to the shortcoming such as common solvent, thereby has limited its application.
Have in the silicone resin-the Si-O-Si-structure, demonstrate the performances such as good weathering resistance, thermotolerance, anti-staining property and chemically stable, be suitable for using as the non-viscous paint composition.But pure silicone resin needs hot setting, and long construction inconvenience set time, and with the poor adhesive force of metallic substance, poor solvent resistance, physical strength are not high simultaneously.CN101955727A discloses a kind of non-viscous paint of pliable and tough water-fast steam, and this non-viscous paint is take polyester modified organic silicon resin and Resins, epoxy as main component, have snappiness good, can tolerate water vapour, characteristics easy to clean.CN102079938A discloses a kind of high temperature resistant non-viscous paint, and the main component of this non-viscous paint is the organic-silicon-modified saturated polyester by the preparation of silicone resin intermediate reaction.Described high temperature resistant non-viscous paint has good resistance toheat, non-viscosity energy and good metal adhesion.With other resins such as acrylic resin and Resins, epoxy silicone resin is carried out chemical modification, can improve the performance of silicone resin.But the metal adhesion of acryl-modified silicone resin resin is poor, can not satisfy the requirement of non-viscous paint; Shock resistance and the hardness of epoxy resin modified organosilicon resin are low, all can not satisfy the requirement of non-viscous paint.
