Glass fiber reinforced polyethylene powder

Abstract

The invention discloses a glass fiber reinforced polyethylene powder, which comprises the following components by mass: 50%-70% of polyethylene, 5%-15% of glass fiber, 10%-15% of a compound halogen-free flame retardant, 5%-15% of nano-calcium carbonate, 0.1%-0.5% of calcium stearate, 0.1%-1% of an antioxidant, and 0.5%-1% of pentaerythritol stearate. The glass fiber is alkali-free chopped glass fiber that has a diameter of 8-15micrometers and a surface treated by a silane coupling agent. The powder provided by the invention utilizes the blending synergistic effect of glass fiber and nano-carbon fiber, significantly improves the impact toughness, rigidity and heat resistance of the material, and has good halogen-free flame retardant effect, can achieve the UL94V-0 flame retardant grade, and has good use effect and social and economic benefits when applied to construction, transportation, electric wires and cables, chemical machinery and other fields.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to glass fiber reinforced polyethylene fuel powder. Background technique [0002] Due to its low price, easy molding and processing, and many excellent properties, polyethylene has a large market demand and is widely used. However, polyethylene has disadvantages such as poor stress crack resistance, flammability, insufficient heat resistance and poor impact toughness, which limit its application range. Contents of the invention [0003] The object of the present invention is to provide a glass fiber reinforced polyethylene fuel powder with good mechanical properties and excellent heat resistance. [0004] The technical solution adopted by the present invention to solve the technical problem is: a glass fiber reinforced polyethylene fuel powder, the components of which are proportioned by mass percentage: polyethylene 50% to 70%, glass fiber 5% to 15%, compound Formulat...
