Problems solved by technology

According to relevant statistics, tragic events caused by smoke in fires account for more than one-third of the total death toll. There are many types of flame retardants available for poly-9-aminononanoic acid fibers, but they are generally single Addition, although it can improve the flame retardancy of poly-9 amino nonanoic acid fiber, the flame retardant effect is not particularly ideal. In addition, the addition of flame retardant is relatively large, which has a certain impact on other properties of poly-9 amino nonanoic acid fiber, such as Affect its fluidity, plasticity, etc.

Embodiment 1

[0009] Embodiment 1 provides a modified poly-9-aminononanoic acid and its preparation method, which is composed of the following components by weight ratio: poly-9-aminononanoic acid: 72%; red phosphorus: 5%; decabromodiphenylethane: 15% %; Melamine Phosphate: 5%; Strengthening Agent: 1%; Flow Modifier: 1%; Antioxidant: 0.5%; Lubricant: 0.5%.

[0010] The above raw materials are prepared according to the weight ratio, and then poly-9 aminononanoic acid is dried on a vacuum dryer at a temperature of 85-90 degrees for 6-8 hours, and then mixed with red phosphorus, decabromodiphenylethane, melamine phosphate, Strengthening agent, flow modifier, antioxidant and lubricant are weighed according to the proportion and mixed in the mixer at low speed for 15 minutes. The gap between the mixing blade and the cylinder wall of the mixer should not be greater than 3mm. The mixing effect should be visually observed that the various particles and powders are basically uniform, without obvious...

Abstract

The invention relates to modified poly-9 aminononanoic acid and a preparation method thereof. The modified poly-9 aminononanoic acid is composed of the components of, by weight: 68-77% of poly-9 aminononanoic acid, 4-6% of red phosphorus, 13-15% of decabromodiphenylethane, 3-5% of melamine phosphate, 1-2% of an enhancer, 1-2% of a flow modifier, 0.5-1% of an antioxidant, and 0.5-1% of a lubricant. According to the invention, a phosphorus-series flame-retardant, a nitrogen-series flame-retardant and a halogen-series flame-retardant are composed, such that a maximal synergetic effect of the flame-retardants is developed. A flame-retarding effect of nylon products is greatly improved, and dose of flame-retardant can be reduced, such that cost is reduced. Also, compatibility between the flame-retardant and resin is improved, such that a synergetic effect of flame-retardant is optimized.

Description

technical field [0001] The invention relates to a modified composite material of high molecular polymer, more specifically, the invention relates to a modified poly-9-amino nonanoic acid composite material. In addition, the present invention also relates to a method for preparing modified poly-9-aminononanoic acid. Background technique [0002] With the development of society, consumers and manufacturers pay more and more attention to the fire protection requirements of daily necessities such as electronic appliances. Unmodified nylon has poor flame retardancy, its vertical combustion can only reach UL94 V-2 level, its oxygen index is about 24, and it will drip during combustion. It is easy to cause fire, and the vertical combustion of modified nylon can reach V-0 level, which greatly improves its fire safety on finished products. Especially in the field of electronic products, countless fires have been caused by nylon, causing great losses. Therefore, the flame-retardant ...
