Polycarbonate/glass fiber alloy used for cold resistant housing of intelligent water meter and preparation method thereof

Abstract

The invention discloses polycarbonate / glass fiber alloy used for the cold resistant housing of an intelligent water meter and a preparation method thereof. The polycarbonate / glass fiber alloy comprises, by weight, 30 to 50 parts of PC, 30 to 50 parts of an PC recycled material, 0.3 to 0.5 part of a fireproof agent FR2025, 0.5 part to 2 parts of titanium dioxide, 9.5 to 11.5 part of glass fiber, 2 to 5 parts of EMA, 0.1 to 0.5 part of an anti-oxidant1010, 0.1 to 0.5 part of an anti-oxidant 168, 0.3 to 0.5 part of an ultraviolet resistant agent UV-531, 0.03 to 0.08 part of diffusion powder EBS, 0.04 to 0.08 part of ultramarine blue powder, 0.02 to 0.04 part of iron oxide red powder 0.005 to 0.01 part of high temperature resistant florescent yellow powder and 2 to 5 parts of a cold resisting agent 2602. The alloy has the characteristics of high performance, high cold resistance, high fire retardancy, high impact, high stability, resistance to static electricity and the like, and can be used for preparing the housing of intelligent water meters used in chilly regions and for preparing terminal rows.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to the field of polymer materials for smart meter casings, and in particular to a polycarbonate / glass fiber alloy that can be used to prepare cold-resistant smart meter casings 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...

Problems solved by technology

[0005] (1) Incineration or landfill, because harmful gases such as sulfur dioxide are generated during the incineration process, which can easily cause environmental pollution. Refractory degradability will also cause great harm to the environment, and this method is currently being phased out;

[0006] (2) Simple recovery and granulation of defective materials, defective products or recycled products without any modification, downgraded to ordinary plastics, although it solves the environmental problem Pollution problems, but failed to fully utilize the economic value of these waste materials
