Description
Technical field
The invention belongs to the technical field of metal surface spraying, more particularly, the present invention relates to a kind of technique at metal surface spraying non-sticking lining composition.
Background technology
Non-viscous paint has advantages of low-surface-energy and high-fire resistance, mainly is coated on the metal surfaces such as aluminium, cast iron, stainless steel, plays protection, decoration, the function affect such as heat-resisting, not sticking, easy clean.The long-term temperature of using of non-viscous paint 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-sticking lining over more than 30 year, its main component mostly is still polytetrafluoroethylene (PTFE) (PTFE) and is the macromolecular material of main component.
Polytetrafluoroethylene (PTFE) is the perfluoro polymer that is formed by the tetrafluoroethene copolymerization.It is high that polytetrafluoroethylene (PTFE) 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 design features such as shielding action to main chain, it is little that these characteristics have determined that it has a coefficient of friction, do not absorb water, sticking, do not fire, against weather is good, and the characteristics such as serviceability temperature wide ranges and dielectric properties excellence are so that fluorine coating has possessed the good characteristic that other coating does not possess.But polytetrafluoroethylene (PTFE) 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 organic siliconresin-the Si-O-Si-structure, demonstrate the performances such as good weatherability, heat resistance, anti-staining property and chemically stable, be suitable for using as the non-viscous paint composition.But pure organic siliconresin needs hot setting, and long construction inconvenience hardening time, and with the poor adhesive force of metal material, poor solvent resistance, mechanical 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 epoxy resin as main component, have pliability good, can tolerate steam, 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 organic siliconresin intermediate reaction.Described high temperature resistant non-viscous paint has good heat resistance, non-viscosity energy and good metal adhesion.With other resins such as acrylic resin and epoxy resin organic siliconresin is carried out chemical modification, can improve the performance of organic siliconresin.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.
