Abstract

The invention discloses a manufacture method of a degradable fluorescent plastic housing material for mobile phones. The manufacture method includes: mixing well corn starch with 30-60% by weight of furfural resin, polyhydroxyalkanoate, elastomer, shell powder, eggshell powder, a flame retardant, a plasticizer and a stabilizer, adding the mixture into a stirrer, and stirring at 78-88 DEG C for 20-30 min to obtain a product A; mixing well an antioxidant with the balance of the furfural resin, polyhydroxyalkanoate, elastomer, shell powder, eggshell powder, flame retardant, plasticizer and stabilizer, adding the mixture into the stirrer, and stirring at 78-88 DEG C for 20-30 min to obtain a product B; mixing the product A and the product B; feeding the mixture into a twin-screw extruder, melting and blending, extruding, cooling, and granulating, wherein extruding is performed under extrusion temperature of 200-230 DEG C, nose temperature of 210-240 DEG C and screw rate of 110-160 rpm. Themanufacture method is simple and easy to perform; the manufactured material herein is degradable, so that the quantity of waste housings of mobile phones in the environment can be greatly decreased,and the environmental pollution pressure is relieved.

Description

technical field [0001] The invention relates to a plastic mobile phone casing, in particular to a method for manufacturing a degradable mobile phone fluorescent plastic casing material. Background technique [0002] With the development of science and technology, people's lives are becoming more and more convenient. With the emergence of various consumer electronics products, industrial control equipment electronics products, and vehicle-mounted electronics products, people spend more and more time in contact with these electronics products. More and more attention is paid to the safety and usability of mobile phones, and mobile phones are one of the most prominent ones. During the use of mobile phones, in order to protect the safety of mobile phones and prolong the service life of mobile phones, mobile phone cases have emerged as the times require.
