Abstract

The invention discloses a glass fiber reinforced and high flame retardancy modified polyethylene composite material, comprising the following components by the weight percent: 45-60% of polyethylene, 20-40% of glass fiber, 10-20% of main fire retardant, 2-6% of auxiliary flame retardant, 0.3-0.5% of anti-dripping agent, 0.1-1% of antioxidant, and 0.1-1% of lubricant. Compared with the prior art, the glass fiber reinforced and high flame retardancy modified polyethylene composite material has the beneficial effects that the prepared polyethylene composite material disclosed by the invention has the characteristics of being high in fire resistance, high in mechanical strength, better in mobility, excellent in electrical property and the like, achieves the UL94V-0 grade of flame retardant effect, and can be widely applied to the industries such as electric appliances, automobiles, chemical engineering, machinery, packaging and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a glass fiber-reinforced and highly flame-retardant modified polyethylene composite material. Background technique [0002] Polyethylene is light, non-toxic, has excellent dielectric properties, chemical stability, corrosion resistance, etc., and is cheap, easy to form and process, and can be widely used in electrical appliances, chemicals, food, machinery, packaging and other industries. However, due to its low oxygen index, flammability, and a large amount of heat generated during combustion, it is easy to spread flames and cause large fires. Therefore, it is particularly important to deal with the flame retardant problem of polyethylene. Contents of the invention [0003] The purpose of the present invention is to provide a glass fiber reinforced and highly flame retardant modified polyethylene composite material with good flame retardancy, heat resistance and mech...
