Embodiment 1
[0026] The polyester material is composed of the following raw materials by weight: 100 parts of polyester and 10 parts of flame retardant.
[0027] The preparation method comprises the following steps: after melting the polyester in an open mill, adding a flame retardant to disperse evenly; placing the mixed raw materials in a twin-screw machine, extruding by melting, and granulating.
[0028] The flame retardant is composed of flame retardant A and flame retardant B in a mass ratio of 1:5.
Embodiment 2
[0030] It is basically the same as Example 1, the only difference is:
[0031] The flame retardant is composed of flame retardant A and flame retardant B in a mass ratio of 1:6.
Embodiment 3
[0033] It is basically the same as Example 1, the only difference is:
[0034] The flame retardant is composed of flame retardant A and flame retardant B in a mass ratio of 1:7.

Abstract
The invention discloses a composite flame retardant for plastics. The composite flame retardant for plastics is compounded by an N-phosphorus compound substituted phosphinimine type flame retardant and a phosphonate type flame retardant. Compared with the prior art, the composite flame retardant for plastics of the present invention has less total amount of flame retardant added, good flame retardancy and little influence on the mechanical properties of materials. In the field of plastics, it has a good application prospect.
Description
technical field [0001] The invention relates to the field of flame retardant technology, in particular to a composite flame retardant for plastics. Background technique [0002] Plastic is ubiquitous in nearly every aspect of modern life. Its easy-to-form properties facilitate a wide range of applications from packaging, transportation and construction to consumer electronics, automotive and aerospace. In particular, high-performance plastic polymers are increasingly used to reduce weight and improve fuel efficiency in aviation and automobiles, where plastic properties are critical. However, plastics are inherently flammable and subject to a high risk of fire, so research and development of flame retardants, especially halogen-free flame retardants, are being developed to improve safety and reduce risks. Phosphorus-based flame retardant is a low-smoke, low-toxic, environmentally friendly halogen-free flame retardant, and has become a hot topic in the field of halogen-free ...
