Embodiment Construction

[0007] An organic polymer composite material used to manufacture electric bicycle battery shells, composed of the following components by weight: polystyrene 80%, styrene impact modifier 15%, antioxidant 1.5%, lubricant 1.5% , other additives 2%. Its preparation method is: first weigh the above-mentioned five kinds of raw materials in proportion and then mix them in a mixer at a low speed for 10 minutes. In the case of a cut screw combination, in a good vacuum state, kneading and extruding at a certain screw speed, the water-cooled strands are diced and sieved and dehydrated.

Abstract

The invention discloses a material for battery case for electric bicycle, which is organic macromolecular composite material, comprising the following components based on weight percentages: 80% of polystyrene, 15% of styrene shock resistant modifier, 1.5% of anti-oxidant, 1.5% of lubricating agent and 2% of other auxiliaries. The preparation method is as follows: weighing the five raw materials based on percentages, and mixing them in a blender at low speed for 10 min until no obvious blocks or aggregation exists, and timely milling and extruding the mixture with a parallel equidirectional double-screw extruder under screw combination with certain shearing strength and well kept vacuum condition at certain screw revolving speed, and cooling by water, draw strips, dicing into granules, sieving the granules and dewatering them.

Description

technical field [0001] The invention relates to an organic polymer material, in particular to a battery case material used for an electric bicycle. Background technique [0002] An electric bicycle refers to a mechatronic personal vehicle that uses a battery as an auxiliary energy source on the basis of an ordinary bicycle, and is equipped with motors, controllers, batteries, handlebars, brake handles and other operating components and display instrument systems. It is environmentally friendly and energy-saving. , flexible operation and favored by consumers, as oil prices continue to rise and road congestion is getting worse, more and more people prefer to use electric bicycles as a new means of transportation. The core component of an electric vehicle is the battery, and the battery is protected by a plastic casing. Ordinary plastic casings will age due to wind and sun, and will also be deformed and cracked due to uneven road surfaces, which will affect the normal operation...
