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-viscous paint for metallic surface with wear resisting property and antiseptic property.
Background technology
Non-viscous paint has advantages of low surface energy and high heat resistance, is mainly coated on the metallic surfaces such as aluminium, cast iron, stainless steel, plays protection, decoration, the function affect such as heat-resisting, not sticky, easy clean.The temperature of non-viscous paint life-time service is between 180 DEG C～250 DEG C, thereby selected resin should have, and strong adhesion, Good Heat-resistance, hardness are high, the feature of good mechanical property.
The exploitation of non-viscous paint has had the history of more than 30 years so far, although developed multiplely for applying the coating of non-sticky metallic coating over more than 30 year, its main component is still tetrafluoroethylene (PTFE) mostly for the macromolecular material of main component.
Tetrafluoroethylene is the perfluoro polymkeric substance being formed by tetrafluoroethylene copolymerization.It is high that tetrafluoroethylene has degree of crystallinity, molecular weight is large, there is no side chain in molecule, and fluorine atom is closely arranged in 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 features have determined that it has frictional coefficient, do not absorb water, not sticky, do not fire, weathering resistance is good, and the features such as use temperature wide ranges and dielectric properties excellence, make fluorine coating possess the good characteristic that other coating does not possess.But tetrafluoroethylene is expensive, and there is when construction, poor processability strict to the processing requirements of ground, melt temperature is high and be insoluble to the shortcomings such as common solvent, thereby limited its application.
Have in silicone resin-Si-O-Si-structure, demonstrates the performances such as good weathering resistance, thermotolerance, anti-staining property and chemically stable, is suitable for using as non-viscous paint composition.But pure silicone resin needs hot setting, and long construction inconvenience set time, simultaneously with the poor adhesive force of metallic substance, poor solvent resistance, physical strength is not high.CN101955727A discloses a kind of non-viscous paint of pliable and tough water-fast steam, and this non-viscous paint is taking polyester modified organic silicon resin and epoxy resin as main component, have snappiness good, can tolerate water vapour, feature 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 of preparing by silicone resin intermediate reaction.Described high temperature resistant non-viscous paint has good resistance toheat, non-viscosity energy and good metal adhesion.Silicone resin is carried out to chemical modification with other resins such as acrylic resin and epoxy resin, can improve the performance of silicone resin.But the metal adhesion of acryl-modified silicone resin resin is poor, can not meet the requirement of non-viscous paint; Shock resistance and the hardness of epoxy resin modified organosilicon resin are low, all can not meet the requirement of non-viscous paint.
