Abstract

The invention relates to a flame-retardant abrasion-resistant PET (polyethylene terephthalate) composite material and a preparation method thereof. The flame-retardant abrasion-resistant PET compositematerial is prepared from the following components in parts by weight: 80 to 100 parts of PET, 16 to 20 parts of flame retardant agent, 6 to 10 parts of abrasion resistant agent, 0.1 to 0.3 part of compatiblizing agent and 0.1 to 0.5 part of antioxidant. A beta-BC2N material is a novel material having an orthorhombic crystal system, and is a second hard material only to diamonds. By adopting theflame-retardant abrasion-resistant PET composite material disclosed by the invention, a compound type abrasion resistant agent beta-BC2N material / boron nitride is prepared, and the abrasion resistanceperformance of the composite material is better than that of a single abrasion resistant agent titanium nitride.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a flame-retardant and wear-resistant PET composite material and a preparation method thereof. Background technique [0002] Polyethylene terephthalate (PET) is a widely used polymer resin, which has good fatigue resistance, good heat resistance, excellent dimensional stability and other advantages. In some specific application fields, there are requirements for flame retardancy and wear resistance of PET, and ordinary PET composite materials cannot meet the requirements. [0003] In view of the state of the art, the inventor obtained a flame-retardant and wear-resistant PET composite material through years of production practice. This material has not been reported so far, which has very important practical significance for expanding the application of PET composite materials. Contents of the invention [0004] The object of the present invention is to provide a flam...
