Polycarbonate (PC)/glass fiber (GF) alloy for intelligent water meter housing and preparation method thereof

Abstract

The invention discloses a PC / GF alloy for the housing of an intelligent water meter and a preparation method thereof. The raw material formula of the PC / GF alloy for the housing of the intelligent water meter comprises the following components, by weight, 30-50 parts of PC, 30-50 parts of a recycled material of the PC, 0.5-2 parts of titanium dioxide, 9.5-11.5 of a GF, 2-6 parts of a cold resistant agent E920, 0.1-0.5 parts of an antioxidant 1010, 0.1-0.5 parts of an antioxidant 168, 0.3-0.5 parts of an ultraviolet resistant agent UV-531, 0.03-0.08 parts of diffusion powder EBS, 0.04-0.08 parts of ultramarine blue powder, 0.02-0.04 parts of iron oxide red powder, and 0.005-0.01 parts of high temperature resistant fluorescein powder. All performance indexes of the PC / GF alloy for the housing of an intelligent water meter reach or exceed standards of a national water reticulation system, and the PC / GF alloy which has the characteristics of high performance, high shock resistance, high stability, good cold resistance, stable body, high toughness, standard compliant color, and accordance of environmentally friendly standards and the like can be applied to cold regions.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to the field of polymer materials for smart water meter casings, and in particular to a polycarbonate / glass fiber alloy for smart water meter casings prepared from recycled polycarbonate materials 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 p...

Problems solved by technology

[0005] (1) Incineration or landfill method, because harmful gases such as sulfur dioxide are generated during the incineration process, which can easily cause environmental pollution, and landfill method, PC 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
