Abstract

The invention discloses a high-flame-retardancy halogen-free non-reinforced polyamide (PA) material and a preparation method thereof. The invention is characterized in that the high-flame-retardancy halogen-free non-reinforced PA material comprises the following components in parts by weight: 68-87 parts of PA, 0-3 parts of compatible toughener, 0.2-2 parts of antioxidant, 0.1-1 part of organosilicon lubricant, 12-22 parts of halogen-free flame retardant, 0.1-0.2 part of anti-dripping agent, 1-4 parts of MCA (melamine cyanurate) and 0.5-1.5 parts of color master batch. The high-flame-retardancy halogen-free non-reinforced PA material has the advantages of high mechanical property retentivity, favorable flame-retardant effect and excellent tracking index. The method is simple to operate, has the advantages of low cost, high production benefit and high and stable mechanical properties of the material, is very suitable for industrial production, can prolong the service life of the material, and can reduce the environmental pollution.

Description

technical field [0001] The invention relates to a highly flame-retardant halogen-free non-reinforced polyamide material and a preparation method thereof, belonging to the technical field of polymer materials and processing. Background technique [0002] Polyamide resin (PA) has excellent characteristics such as wear resistance, firm quality, cold resistance, non-toxicity, corrosion resistance, easy molding, and easy dyeing. In recent years, due to the dioxin problem, some brominated flame retardants have been banned by the EU RoHS directive. With the global advocacy of the harmonious and sustainable development of human beings and the ecological environment, and the increasingly stringent international environmental protection legislation, the development of high-efficiency, halogen-free PA flame-retardant technology has become an urgent problem to be solved. [0003] The existing method of modifying non-halogenated non-reinforced polyamide materials is difficult to achieve...
