Description

technical field

[0001] The invention relates to the field of polymer materials, in particular to the field of polycarbonate / ABS alloy, in particular to a polycarbonate / ABS alloy which can be used to prepare cold-resistant smart meter housings and a preparation method thereof. Background technique

[0002] Polycarbonate (PC) is a general-purpose plastic containing carbonate groups. According to the structure of ester groups, it can be divided into aliphatic, aromatic and other types. It is a colorless and transparent amorphous thermoplastic material. Its chemical The property is resistant to weak acid, weak alkali, neutral oil, ultraviolet light and strong alkali, and its physical property is linear expansion rate: 38×10cm / cm 2 , The thermal deformation temperature is 135°C, and it has the disadvantages of poor stability, easy cracking due to stress, low impact resistance to notches, poor wear resistance, low adhesion to metal parts, high viscosity, poor fluidity and affectin...
