Matte TPO skin material with low processing viscosity as well as preparation method and application of TPO skin material

The invention provides a matte TPO skin material with low processing viscosity as well as a preparation method and application of the TPO skin material. The TPO skin material is formed by filling a thermoplastic polyolefin (TPO) with nanoparticles, wherein the mass ratio of the TPO to the nanoparticles is (90-99.5):(0.5-10); and the nanoparticles include one or more selected from the group consisting of multi-layer graphene, carbon nanotubes, monodisperse polystyrene microspheres, manganese oxide nanowires, iron tetroxide nanoparticles, fumed silica, and nano carbon black particles. The nanoparticles are packed in the TPO, so that the free volume of the polymer is increased, and the density of entanglement points is reduced; at the same time, interface slip occurs between the nanoparticlesand the polymer, the interface slip acts as a lubricant to reduce the viscosity of the system, so that the process temperature of operation such as mixing, calendaring and extrusion in the material processing process is reduced; the nanoparticles play a matting effect; the added nanoparticles have little effect on the mechanical properties of the material and improves the friction-resistant coefficient; and the TPO skin material provides guidance for industrial production.

Low-gloss low-smoke halogen-free flame-retardant polycarbonate composite material

The invention specifically relates to a low-gloss low-smoke halogen-free flame-retardant polycarbonate composite material, belonging to the field of polymer composite materials. The polycarbonate composite material comprises the following components by weight: 70-90% of branched polycarbonate resin, 5-20% of PC composite resin, 1-5% of an epoxy-reactive compatilizer, 0.5-2% of a matting agent, 0.1-1% of a sulfonate flame retardant, 0.1-1% of a polysiloxane flame retardant and 0.5-1.5% of an auxiliary agent. The polycarbonate composite material of the invention has the advantages that the PC composite resin, the epoxy-reactive compatilizer and the matting agent have good synergistic effect and ensure low glossiness of the composite material without influence on the flame retardancy and smoke density of the composite material; high-concentration epoxy groups play the roles of chain extension and cross-linking, so certain extinction effect is exerted on the polyester material; and since branched PC is compounded with the sulfonate flame retardant and the polysiloxane flame retardant, the testing smoke density in the combustion process is very low on the basis of ensured flame retardancy.
