Abstract

The invention discloses a long glass fiber enhanced polypropylene composite material water meter casing and a manufacture method of the long glass fiber enhanced polypropylene composite material water meter casing. A thermal plastic composite material water meter casing comprises the following ingredients: blending alloy, auxiliary agents, color powder, antioxidants and ultraviolet absorbers, wherein the blending alloy consists of glass fiber, polypropylene and/or polypropylene modified materials. The thermal plastic composite material water meter casing made by adopting an injection molding forming process has the characteristics of high-temperature resistance, low-temperature resistance, impact resistance, creep deformation resistance, water pressure resistance, hydrolysis resistance, no heavy metal, long service life, low cost, environmental-friendly effect and the like, is easy to process and conforms to the industrial standard of the national plastic water meter casing material, so the thermal plastic composite material water meter casing is particularly suitable for large-scale industrial production and wide popularization and application.

Description

technical field [0001] The invention relates to an engineering plastic water meter casing and a manufacturing method thereof, in particular to an engineering plastic water meter shell with low specific gravity, high and low temperature resistance, high impact resistance, hydrolysis resistance, chemical (reagent) corrosion resistance, (static) water pressure resistance, and non-toxicity. 1. A non-polluting long glass fiber reinforced polypropylene composite material water meter casing and a manufacturing method thereof. Background technique [0002] At present, the commonly used metal water meter shells are mainly made of cast iron through sand casting and secondary processing. The production process consumes a lot of energy, has many procedures, long cycle, heavy environmental pollution, and poor reproducibility of product quality. Cast iron components are prone to rust, which will not only greatly affect the service life, but also affect the water quality, thus bringing ser...
