The invention discloses a self-cleaning material for
signal lines. The self-cleaning material is prepared from the following ingredients, by weight, 30-40 parts of hydroxyl-terminated
fluorine-containing
polyester polysiloxane, 10-20 parts of
chitosan-
adipic acid dual
coating modified
calcium carbonate, 40-60 parts of diisocyanate
fluoride, 20-30 parts of a PS-b-PDMS-b-PS segmented
copolymer, 10-15 parts of POE-g-MAH and 15-25 parts of a
processing aid. The invention also discloses a preparation method of the self-cleaning material for
signal lines. The product has characteristics of low
surface tension of fluoroalkyl-containing and
siloxane-containing structures, hydrophobicity, oleophobicity and the like. When the product is applied to
signal lines, the product has advantages of self-cleaning function, high anti-
pollution ability, flexibility, good elasticity, good hand feeling, good weatherability, chemicals resistance,
antibacterial property and the like, and is not easy to scratch or leave a trace. When in use, the product can keep bright in appearance for a long time. thus, the defect that most existing
fluorine-containing materials have high
hardness and inflexible molecular chain and are not applicable to
signal lines is overcome.
