Problems solved by technology

[0003] At present, since flame retardants are all powders, it is extremely difficult to mix them evenly when mixed with raw materials, and the dust raised during mixing will pollute the surrounding environment and affect health. At the same time, it can also reduce the cost of producing plastic devices

Abstract

The invention discloses a phosphor-nitrogen halogen-free flame-retardant master batch used for engineering plastics, and a preparation method thereof. The phosphor-nitrogen halogen-free flame-retardant master batch used for the engineering plastics comprises components by mass: 70%-90% of a phosphor-nitrogen halogen-free flame retardant, 10%-20% of a carrier, 3%-5% of a dispersant and 1%-3% of a coupling agent. The prepared master batch has the characteristics of high concentration, low cost and convenient use. Due to the adoption of the phosphor-nitrogen halogen-free flame retardant, the master batch has the characteristics of small dosage, small influence on mechanical and electrical properties of a plastic matrix, good flame-retardant effect and excellent processing properties. By using the master batch to modify the flame retardance of the plastics, not only can production process be simplified, but also production efficiency can be increased; and the problems of non-uniform distribution and dust pollution possibly caused by directly adding the flame retardant can be prevented. The master batch provided by the invention also meets flame-retardant and environment-friendly requirements of efficiency, low smoke, halogen free and no poison gas release, fits a development trend of non-halogen, non-toxicity, no dust pollution and reduced cost for flame retardance of the plastics, and has wide market prospects.

Description

technical field [0001] The invention relates to a flame-retardant masterbatch and a preparation method thereof, in particular to a phosphorus-nitrogen-halogen-free flame-retardant masterbatch for engineering plastics and a preparation method thereof. Background technique [0002] Engineering plastics are a class of high-performance polymer materials that can be used as structural materials, withstand mechanical stress in a wide temperature range, and are used in harsh chemical and physical environments, and have good mechanical properties and dimensional stability. Engineering plastics are widely used in various fields due to their exceptional performance, but overall there are too many products with relatively low technical content, and some still have defects such as insufficient flame retardancy. In the 21st century, the issue of sustainable development has been paid more and more attention by the governments of various countries. Green chemistry and technology and the in...
