High-impact environment-friendly halogen-free flame retardant reinforced nylon material and preparing method thereof

Abstract

The invention provides an environment-friendly halogen-free flame retardant reinforced nylon material which is low in cost, high in anti-electric-arc capability, controllable in color and stable and reliable in product quality during injection moulding. The environment-friendly halogen-free flame retardant reinforced nylon material comprises, by weight, 15-60% of gather adipic acid diamine, 10-30% of polyamide 6, 3-15% of halogen-free flame retardant A, 5-15% of halogen-free flame retardant B, 3-10% of compatilizer, 0.3-1.5% of nucleating agent, 5-30% of glass fiber and 0.3-1.0% of complex antioxidant. Compared with the prior art, the environment-friendly halogen-free flame retardant reinforced nylon material has the advantages of being low in cost; due to the fact that the halogen-free flame retardant, the antioxygen and the surface nucleating agent are combined and compounded, the flame retardancy of the gather adipic acid diamine is enhanced, the problems that the flame retardant drops easily during surface precipitation and product combustion are effectively solved, and the anti-electric-arc capability of the material is improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-impact environment-friendly halogen-free flame-retardant reinforced nylon material and a preparation method thereof. Background technique [0002] Nylon, as a man-made polymer, fiber and plastic, was invented and created by Wallace Carothers of DuPont Company in Wilmington, USA on February 28, 1935, and it was launched in the market in 1938 and entered the people's in daily life. With various improvements such as reinforcement, toughening, and flame retardancy, nylon products meet the needs of various fields, and thus become one of the most demanded and used engineering plastics. However, with the development of society, people pay more and more attention to environmental protection, and more and more halogen-free flame-retardant nylons emerge as the times require. [0003] Most of the traditional halogen-free flame-retardant nylon uses coated red phosphorus o...

AI Technical Summary

Problems solved by technology

[0003] Most of the traditional halogen-free flame-retardant nylon uses coated red phosphorus or melamine salt (MCA) as the flame retardant, and the products that use coated red phosphorus as the flame retardant are mostly red or black, and there are limitations in the use of colors; And it is easy to produce phosphorus-containing gas during the preparation process, which has pollution problems to the environment; at the same time, if melamine salt (MCA) is used as a flame retardant product, it is prone to surface premature death in the process of injection molding into parts. Injection molding into black or colored parts is prone to water marks and dripping when burning. In addition, the traditional halogen-free flame-retardant nylon uses a single flame retardant, and there are few types of compounding, which has product limitations. In this regard, it is particularly important to find a halogen-free flame-retardant nylon material with controllable color and stable and reliable quality during injection molding
