Halogen-free flame-retardant conductive polypropylene composite material

Abstract

A halogen-free flame-retardant conductive polypropylene composite material belongs to the technical filed of polymer materials. The halogen-free flame-retardant conductive polypropylene composite material comprises, by weight, 81-87 parts of a polypropylene resin, 14-21 parts of a compatilizer, 7-12 parts of an elastomer, 23-31 parts of a flame retardant, 0.6-1.1 parts of an antioxidant, 0.4-0.8 parts of graphite, 17-24 parts of a glass fiber, 0.8-1.3 parts of a processing assistant and 1.8-2.6 parts of carbon black. Test results show that the halogen-free flame-retardant conductive polypropylene composite material has a bending strength of above 56-73MPa, a notch impact strength of above 12.5-15.2kj / m<2>, a thermal deformation temperature of 121-146DEG C and a flame retardation property of V-0 (UL-94-V-0-1.6mm), so the composite material has excellent strength and flame retardation property; the flame retardant is reasonably selected, so the composite material free from halogens is environmentally friendly; and the surface does not generate static electricity, so the safety is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a halogen-free flame-retardant conductive polypropylene composite material. Background technique [0002] Polypropylene resin has excellent physical and mechanical properties and is widely used in various industries. In particular, polypropylene reinforced with glass fibers has the characteristics of light specific gravity and high strength, so it can be widely used in automobiles, construction and other fields to replace steel. However, due to the good insulation of polypropylene materials, it is easy to accumulate charges on the surface to form static electricity. After the accumulation of static electricity, it is easy to hurt people or cause other losses. Therefore, reducing the accumulated static electricity on the surface of polypropylene composite materials is a requirement of the automotive industry for interior decoration. [0003] In addition, as...
