Abstract

The invention discloses a flame retardant nylon material. The flame retardant nylon material comprises, by weight, 130-150 parts of nylon, 4-6 parts of lauryl mercaptan, 2-3 parts of stearic acid, 1-2parts of diacetone acrylamide, 2-4 parts of calcium aluminate, 0.5-1 part of diisocyanate, 0.7-1 part of 2-mercaptobenzimidazole, 3-5 parts of ammonium polyphosphate, 15-20 parts of expanded perlite,16-20 parts of thionyl chloride, 2-4 parts of ethylenediamine, 10-18 parts of a sol emulsion and 0.4-1 part of dodecyltrimethylammonium chloride. When the material is burned, organic matters are carbonized, and then are dispersed among expanded perlite layers to isolate the direct calcination of flame and obstruct the heat conduction, so the flame retardant nylon material has very good synergistic effects, prolongs the flame-retardant time and improves the fireproof performance of finished products.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a flame-retardant nylon material and a preparation method thereof. Background technique [0002] Due to its good mechanical properties, processability, heat resistance, corrosion resistance, and self-lubricating properties, nylon is widely used in various fields such as electronic communications, textiles, and chemical manufacturing. However, nylon also has disadvantages. Its chemical structure is mainly composed of carbon and hydrogen. Nylon is highly flammable, and there are potential fire hazards in people's daily life and production. Sexual smoke can cause serious consequences in a fire. In view of this, many countries are currently attaching great importance to the flame retardant modification of nylon, and are committed to the development and production of various flame retardants; [0003] In recent years, with the rapid development of the country's current manufactu...
