Abstract

The invention discloses environment-friendly phosphorus-nitrogen one-component intumescent flame retardant-modified nylon 6 which is prepared from the following components in parts by weight: 50-90 parts of nylon 6, 5-25 parts of a phosphorus-nitrogen one-component intumescent flame retardant, 2-10 parts of an inorganic synergistic flame retardant, 2-10 parts of a compatilizer and 1-5 parts of an antioxidant. The invention further discloses a preparation method of the environment-friendly phosphorus-nitrogen one-component intumescent flame retardant-modified nylon 6. A safe and environment-friendly high-performance nylon 6-modified material with good mechanical properties and a good flame-retardant property is obtained through introducing environment-friendly common flame-retardant nylon 6 with the good flame-retardant property and water solubility resistance of the phosphorus-nitrogen one-component intumescent flame retardant and the inorganic synergistic flame retardant; and the environment-friendly phosphorus-nitrogen one-component intumescent flame retardant-modified nylon 6 has good development potential and wide application prospects.

Description

technical field [0001] The invention belongs to the field of polymer material modification, and in particular relates to an environment-friendly phosphorus-nitrogen single-component intumescent flame retardant modified nylon 6 and a preparation method thereof. Background technique [0002] Compared with inorganic and metal materials, the flammability of polymer materials has seriously restricted their wider development and application. Therefore, it is of great scientific significance and application value to carry out relevant flame retardant research. Studies have confirmed that it is an effective method to improve the flame retardancy of polymer materials by adding flame retardants; therefore, the development of high-efficiency flame retardants has become a hot spot in the field of flame retardancy of polymer materials. [0003] Nylon 6 has excellent comprehensive properties and occupies an important position in the field of engineering plastics. However, while it has e...
