Problems solved by technology

At present, the following three materials are mainly used to manufacture membrane switches: ① Polyvinyl chloride (PVC), the panel made of PVC is stable to acid, alkali and salt at room temperature, has good wear resistance, flame resistance and self-extinguishing, noise and shock absorption, Good electrical insulation, but poor thermal stability; ② Polycarbonate (PC), the panel made of polycarbonate has low water absorption, good dimensional stability, excellent bending, tensile and compressive strength, and heat resistance Excellent cold resistance, electrical insulation and atmospheric aging resistance, but it has poor chemical resistance, poor fatigue resistance, and is prone to stress cracking
③PET resin, the panel made of PET resin is currently the most popular switch panel on the market, because it has good chemical resistance, is insoluble in general

Abstract

The invention relates to an antibacterial fluorescent PET/PC (Polyethylene Terephthalate/Polycarbonate) alloy and a preparation method thereof and belongs to the technical field of high polymers. The antibacterial fluorescent PET/PC alloy comprises the following components in parts by weight: 20-40 parts of PET, 80-100 parts of PC, 1-3 parts of a compatilizer, 0.5-1 part of antioxidant 1010, 0.2-0.5 part of antioxidant 168, 2-5 parts of rare earth aluminate noctilucent powder, 1-3 parts of ultraviolet absorber (UV) and 1-3 parts of a natural antibacterial agent. According to the product, the PET and PC are compounded, so that the prepared product has excellent performances of the PET and PC, is high in heat resistance and high in dimensional stability and has a sterilization function. According to the antibacterial fluorescent PET/PC alloy, light-induced energy storage noctilucent powder which is harmless to a human body is added, so that the product has the fluorescence characteristic, and normal use of a switch can be guaranteed when the light source is dark.

Description

technical field [0001] The invention belongs to the technical field of macromolecules, and in particular relates to an antibacterial fluorescent PET / PC alloy and a preparation method thereof.
