Problems solved by technology
[0004] However, the current option 1 still has certain limitations. A mature and efficient new phosphorus-containing flame retardant has not yet appeared on the market to replace the widely used aluminum diethylphosphinate. In terms of cost economy, flame retardant efficiency, etc. In terms of consideration, more efficient new phosphorus-containing flame retardants are still in the development process
For the second option, researchers mostly use existing compounds and phosphorus-containing flame retardants to try synergistic effects. For example, in some of the above-mentioned patents, there are problems such as the use of halogens and antimony white, the problem of sacrificing other properties of the resin, and the prohibition of silicon in some products. questions and so on

Abstract
The invention relates to a halogen-free flame-retardant polyamide composite material and a preparation method thereof. The composite material comprises polyamide resin, filler, phosphinate, a melaminederivative, borate, a flame-retardant synergist and other assistants. The flame=retardant synergist used in the invention has a significant improvement effect on the flame retardant property, can improve the heat resistance and stability of the material, and has no negative influence on other mechanical properties or electrical properties.
Description
technical field [0001] The invention belongs to the field of polyamide composite materials, in particular to a halogen-free flame-retardant polyamide composite material and a preparation method thereof. Background technique [0002] Since halogen-free flame-retardant reinforced polyamide has excellent electrical properties, mechanical properties, flame-retardant properties, etc., it has a wide range of applications in the fields of electronics and new energy vehicles. With the development trend of miniaturization and thin-wall of many products, higher requirements are put forward for the flame retardant performance of materials. For example, the flame retardant V-0 grade with a thickness below 1.0mm has become the mainstream demand. Phosphorus-based flame retardants are a kind of high-efficiency and environmentally friendly flame retardants with great application prospects in nylon materials, among which aluminum diethylphosphinate is the most typical. Pure aluminum diethyl...
