Abstract

The invention discloses a high-toughness antimony system compound flame retardant nylon material and a preparation method thereof. The nylon material is prepared from, by weight, 50-70 parts of nylon 66, 30-50 parts of nylon 6, 3-8 parts of antimony trioxide, 8-15 parts of a flame retardant A, 10-20 parts of a flame retardant B, 3-8 parts of plasticizer, 15-25 parts of a toughening agent, 2-6 parts of a coupling agent, 2-6 parts of a lubricating agent and 1-3 parts of an antioxidant agent. Two resin of nylon 66 and nylon 6 are adopted as composite basic materials, performance advantages of the two resin are combined, the high-toughness antimony system compound flame retardant nylon material has good flame retardant and smoke inhibiting performances and excellent impact resistance and processing performance by optimizing matching and adding auxiliaries for modification. The high-toughness antimony system compound flame retardant nylon material is prepared from halogen-free and nontoxic environment-friendly raw materials and auxiliaries, and the prepared product is an environment-friendly high-toughness antimony system compound flame retardant nylon material.

Description

technical field [0001] The invention belongs to the technical field of flame-retardant materials, and in particular relates to a high-toughness antimony compound flame-retardant nylon material and a preparation method thereof. Background technique [0002] Nylon 66 (PA66) is a polar semi-crystalline polymer. Because it has more amide groups, it can form more hydrogen bonds, so it has strong mechanical properties and a high melting point, so it is widely used as a engineering plastics. The chemical and physical properties of nylon 6 (PA6) are similar to PA66, but PA6 has a lower melting point and a wider process temperature range, and its impact resistance and solubility resistance are better than PA66. Both PA66 and PA6 contain amino groups, which will release a small amount of inert gas when they are burned and decomposed. Therefore, the combustion process is relatively slow and has certain flame retardant properties. sex. [0003] At present, nylon (PA) is more and more...
