Fluorocarbon resin refers to fluorine-containing resin or polymers containing a large number of C-F bonds in their molecular structure. Because the electronegativity of fluorine atoms is large, the carbon-fluorine bond energy is strong, and the fluorine atoms are closely arranged around the carbon main chain, which can provide better protection. The special structure gives fluorocarbon resin excellent weather resistance, chemical resistance, heat resistance, low temperature resistance and other properties.
As a high-performance resin material, fluorocarbon resin has been widely used in many fields due to its excellent performance.
1)Fluorocarbon resin has strong C-F bonds as its skeleton. Compared with other resins, it has better heat resistance, chemical resistance, cold resistance, low-temperature flexibility, weather resistance and electrical properties, and due to its good crystallinity , so it has non-adhesive and non-wetting properties.
2)Due to the excellent weather resistance, corrosion resistance and chemical resistance of fluorocarbon resin, exterior wall coatings made of fluorocarbon resin as film-forming material have extremely high weather resistance, but the preparation cost of fluorocarbon resin coating is very high. High, mostly used in fields with special requirements.
3)Fluorocarbon resin has certain environmental protection properties and can be recycled and reused, further reducing the burden on the environment. However, the cost of fluorocarbon resin recycling is relatively high and it is still in its initial stage. However, with technological advancement and cost reduction, the application prospects of fluorocarbon resin recycling will be broader.
In addition, experiments have shown that the double-layer energy-storage luminescent coating prepared based on fluorocarbon resin has the advantages of heat resistance, water resistance, weather resistance and scratch resistance. The initial brightness is higher than that of a single-layer energy-storage luminescence coating, and the afterglow time is longer. Although the price of fluorocarbon resin is relatively high, as the main film-forming substance of the bottom layer and surface layer, it has good compatibility and excellent film layer performance.
According to its structure and performance characteristics, fluorocarbon resin can be mainly divided into the following three types: PTFE (polytetrafluoroethylene), PVDF (polyvinylidene fluoride) and FEVE (copolymer of fluoroolefin and alkyl vinyl ether or ester) things)
Fluorocarbon resin is a material with wide application value, and its application fields cover many aspects:
