Problems solved by technology

At present, the flame retardants and antistatic agents used in the market are mainly additive additives, which can only be evenly distributed in the material when added, and the content of active ingredients of this additive is low. For a good flame retardant and antistatic effect, it is necessary to increase the amount of additives added, which will cause a significant drop in material performance and increase the cost

Abstract

The invention discloses a flame-retardant antistatic nylon material. The nylon material is prepared by mixing, in parts by weight, 60-85 parts of polyamide, 5-25 parts of a toughening agent, 10-20 parts of a mixed agent of antimony trioxide and 1,2-bis(pentabromophenyl) ethane, 0.5-1 part of an antistatic agent and 0.1-0.5 part of an antioxidant, wherein the polyamide has a relative viscosity of 2-3. Mechanical properties of the prepared flame-retardant antistatic nylon 6 meet requirements for preparation of mining machinery tools, and flame retardancy and antistatic level both meet requirements of the MT113-85 standard, and are at a domestic advanced level. The material has permanent flame retardant and antistatic properties, the problem of difficult production is overcome, and popularization of the material becomes possible. The mining machine tools prepared by the material are light in weight, easy to shape and process, and low in price.

Description

technical field [0001] The invention relates to the technical field of nylon materials, in particular to a flame-retardant and antistatic nylon material and a preparation method thereof. Background technique [0002] Nylon has excellent mechanical properties, wear resistance, oil resistance, solvent resistance, and self-lubricating properties. It is one of the engineering plastics with a wide range of uses. Since nylon is an excellent electrical insulating polymer material, its surface resistance is 1014-1016 ohms, its volume resistivity is 1013-1014 ohms, it is easy to generate static electricity, and it has no flame retardancy, which limits the use of nylon in the industry. Applications. With the development of China's synthetic material industry and the continuous expansion of application fields, flame retardants have broad market prospects in various fields such as chemical building materials, electronic appliances, transportation, aerospace, daily furniture, interior d...
