Problems solved by technology

[0006] At present, there is no composite material that uses hydroxyl-terminated fluorine-containing polyester polysiloxane, chitosan surface-modified calcium carbonate, isocyanate, and thermoplastic polyolefin elastomer to prepare fluorine-containing siloxane. Using its low surface energy, self-cleaning effect, good elasticity, and excellent comprehensive performance, it is applied to signal wires to overcome the lack of self-cleaning function of existing signal wires

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a self-cleaning material for signal lines and a preparation method thereof. Background technique [0002] During long-term use, signal wires such as earphone wires often come into contact with oil, moisture, cosmetics, etc. due to storage or wearing. Dirt, oil and water resistance. [0003] Polyurethane (PU) materials have been widely used in many fields and daily life because of their good mechanical properties, low temperature curing, high adhesion strength, and water resistance, solvent resistance, and low temperature resistance. However, with the rapid development and progress of society, higher and newer requirements have been put forward for the protective and decorative properties of materials, especially durability. Facing the new requirements, the original polyurethane materials have shown great shortcomings. , which limits its application, and fluorine-conta...
