AI Technical Summary

Problems solved by technology

However, due to the addition of a large amount of inorganic substances, the compatibility between the inorganic mineral powder and the resin matrix material is deteriorated, resulting in a great decline in the physical and mechanical properties of the final product.
Although the red phosphorus flame retardant system can partially solve the problem of large addition amount and product performance degradation, it is limited by the production of corrosive and toxic gases during the processing of red phosphorus, poor color toning of red phosphorus products, and low ignition point of red phosphorus. The use of red phosphorus flame retardant products

Abstract

The invention discloses high glowing filament flame-retardant reinforced polyamide 66 (PA66), which is prepared from the following materials in parts by weight: 60-80 parts of PA66, 12-15 parts of phenolic fibers, 8-10 parts of a tetrafluoroethylene-hexafluoropropylene copolymer, 10-14 parts of a flame retardant, 5-7 parts of a toughening agent, 1-3 parts of an antioxidant, 2-4 parts of a stabilizer, 0.5-1 part of calcium palmitate and 1-3 parts of the triisopropyl phenyl phosphate. The high glowing filament flame-retardant reinforced PA66 is prepared by optimizing the chemical components, so that the internal structure of polybutylene terephthalate (PBT) plastic is improved on a microcosmic level; the high glowing filament flame-retardant reinforced PA66 has excellent mechanical properties, heat resistance and flame retardant property.

Description

technical field [0001] The invention relates to a plastic, in particular to a high glow wire flame retardant reinforced PA66 and a preparation method thereof. Background technique [0002] Because PA66 has excellent mechanical strength, wear resistance, self-lubricating property, corrosion resistance and good formability, but it has insufficient heat resistance and impact resistance under low temperature conditions, and has defects in dimensional stability and electrical properties. , so that its promotion and use are subject to certain limitations. In recent years, with the development of PA66 modification technology, as a new material for electrical components, it not only requires high rigidity, good heat resistance and dimensional stability, but also requires good processability and flame retardancy. , so flame retardant enhanced PA66 has a great market prospect. [0003] However, pure PA66 resin also has disadvantages such as poor flame retardancy, low mechanical stre...
