Abstract

The invention belongs to the technical field of plastic particles, in particular to a highly flame-retardant and highly wear-resistant plastic particle and a preparation method thereof. The plastic particle solves the problem that since the addition amount of flame retardants in the prior art is large, the mechanical property and wearing resistance of plastic particles decline, the flame retardingeffect of the flame retardants is poor, and surface contamination of products and potential environmental protection hazards are likely to be caused. The highly flame-retardant and highly wear-resistant plastic particle is prepared from nylon, polyetheretherketone, polyphenylene pyridinium diimidazole fibers, ammonium polyphosphate, a flame retardant reinforcing agent, butyl octadecenoate, a silane coupling agent and an antioxidant. The prepared highly flame-retardant and highly wear-resistant plastic particle has stable uniform performance, excellent toughness, wear resistance, oxidation resistance and flame retardancy and a low wearing resistance coefficient, and on the premise of high wearing resistance, a test strip which is made of the plastic particle and is 0.5mm in thickness can pass a UL-V-Level 0 test. The comprehensive performance is excellent.

Description

technical field [0001] The invention relates to the technical field of plastic particles, in particular to a high flame-retardant and high wear-resistant plastic particle and a preparation method thereof. Background technique [0002] Polymer materials are materials based on polymer compounds, including plastics, rubber, fibers, films, adhesives and coatings. Among them, plastics, synthetic fibers and synthetic rubber, known as the three major synthetic materials of modern polymers, have become important materials that are indispensable for national economic construction and people's daily life. Polyamide, commonly known as nylon, is a polycondensation polymer compound with a -CONH structure in its molecule. It is usually obtained by polycondensation of dibasic acids and diamines. PA is widely used to replace copper and other advantages. Non-ferrous metals are used to make machinery, chemicals, and electrical parts, such as diesel engine fuel pump gears, water pumps, high-p...
