Abstract

The invention discloses a long glass fiber reinforced nylon composite material, a preparation method thereof, and an application of the composite material in electric cutters. The composite material comprises 1-2 parts of cyclohexane, 5-7 parts of ethyl stearate, 3-4 parts of maleic anhydride, 1-2 parts of bisphenol A type liquid epoxy resin, 50-70 parts of nylon resin, 20-40 parts of glass fibers, 0.2-1 part of an antioxidant, 0.2-1 part of a lubricant and 0.1-1 part of pigment. The long glass fiber reinforced nylon composite material matrix has high impact performance, greatly reduces use ofa toughening agent, and can meet performance requirements of related products.

Description

technical field [0001] The invention relates to a plastic composition and a preparation method thereof, in particular to a long glass fiber reinforced nylon composite material, a preparation method and an application in electric cutters. Background technique [0002] In power tools, long glass fiber nylon has high impact performance, but currently it is often not tough enough for some brightly colored power tools. At present, in order to improve the toughness of the product, it is necessary to add a toughening agent to meet the requirements. The toughening agent has an effect on the color of the product. In addition, some thermosetting resin adhesives, such as epoxy resin, phenolic resin and unsaturated polyester resin glue After curing, the adhesive has low elongation and high brittleness. When the bonding part is subjected to external force, it is easy to generate cracks and expand rapidly, resulting in cracking of the adhesive layer. It is not fatigue-resistant and cannot...
