Abstract

The invention discloses a preparation method of ABS composite plastic for a shell of an air conditioner remote controller. The preparation method comprises the following steps: mixing polyphosphoric acid and tetrahydrofuran-propylene oxide copolymerization diol, heating and stirring, adding bisphenol F epoxy resin, continuously stirring, adding phthalic anhydride and trimethyl-propane trimethacrylate, heating and stirring, cooling and pulverizing to obtain a prefabricated material a; mixing ABS resin, polycarbonate resin, polystyrene and the prefabricated material a uniformly to obtain a prefabricated material b; and adding talcum powder, trichloroethyl phosphate, pine tar and an antioxidant B215 into the prefabricated material b, feeding into a double-screw extruder and performing extrusion granulation to obtain the ABS composite plastic for the shell of the air conditioner remote controller. The process is simple, convenient to operate, high in benefit, low in cost and suitable for industrialized production. The composite plastic has high shock resistance, high smoothness, high heat stability and high toughness, the brittleness is reduced, the shock resistance is enhanced, and the thermal deformation temperature is increased.

Description

technical field [0001] The invention relates to the technical field of remote controls, in particular to a method for preparing an ABS composite plastic for an air conditioner remote control shell. Background technique [0002] In modern life, remote control has become a standard configuration of almost all electrical appliances. It can be said that we cannot live without a remote control for a day in our daily life. The remote control of the air conditioner is a necessary configuration of the air conditioner. The shell of the remote control of the air conditioner plays an important role in protecting the internal components and ensuring the normal operation of the air conditioner. [0003] Polycarbonate is an amorphous engineering plastic, which is commonly used to prepare air conditioner remote control shells. It has excellent impact strength, thermal stability, gloss, antibacterial properties, flame retardant properties and anti-pollution properties, but its molecular ri...
