Problems solved by technology

Among them, IFR is one of the most promising halogen-free flame-retardant materials due to its advantages of high flame-retardant efficiency, low smoke, low toxicity, and no corrosive gas release. However, although the existing IFR system has other flame-retardant The system has incomparable advantages, but it also has many shortcomings, such as low flame retardant efficiency, poor water resistance, insufficient thermal stability, etc., which seriously restrict its further popularization and application.

Embodiment 1

[0013] 1) Weigh 31.5 parts by weight of melamine and place it in a reaction kettle, add 250 parts by weight of deionized water, slowly add 16 parts by weight of nitric acid dropwise after ultrasonic treatment for 30 minutes, heat up to 90°C after magnetic stirring for 1 hour, and slowly add 33.8 parts by weight of pyrophosphoric acid Sodium, under the action of a magnetic field, pass in neon gas to purge for 1~2h, then continue to stir at 90~100°C, monitor the pH value of the reaction solution, when the pH value is ≥ 6.0, stop the reaction to obtain a white paste, use Wash with deionized water for 3 to 5 times, filter with suction, and then place in a vacuum drying oven at 100°C to dry to constant weight, crush and sieve to obtain melamine pyrophosphate powder for later use;

[0014] 2) Weigh 30 parts by weight of melamine pyrophosphate and 50 parts by weight of polypropylene, and blend them in an ML-E internal mixer at 170°C for 10 minutes, and then transfer the blend to an op...

Embodiment 2

[0018] It is exactly the same as Example 1, except that 24 parts by weight of melamine pyrophosphate and 12 parts by weight of pentaerythritol are added.

Embodiment 3

[0020] It is exactly the same as Example 1, except that 24 parts by weight of melamine pyrophosphate and 8 parts by weight of pentaerythritol are added.

Abstract

The invention discloses a preparation method of a novel flame-resistant material. Melamine, nitric acid, tetrasodium pyrophosphate and the like are taken as raw materials, an antioxidant 1330 and a Sb2O3-diatomite / MOF-5 composite are introduced, and the novel flame-resistant material is prepared through methods including ultrasonic treatment, organic synthesis, physical compounding and the like. The prepared novel flame-resistant material has excellent flame retardancy, is low in production cost and high in flame-retardant efficiency and can meet the flame-retardant requirements through littleaddition.

Description

technical field [0001] The invention belongs to the field of material preparation, and in particular relates to a preparation method of a flame retardant material. Background technique [0002] Polymer materials are closely related to people's production and life, bringing convenience but also danger. Their flammable and fire-prone characteristics seriously threaten people's life and property safety. Flame retardant materials are a class of additives that can prevent polymer materials from being ignited or inhibit flame propagation, and are widely used in the flame retardant treatment of polymer materials. [0003] Polypropylene (PP), as one of the most productive polymer materials, is widely used in the automotive industry, house decoration, electronics and electrical fields. However, PP is a flammable material, its limiting oxygen index (LOI) is only 17.0%~17.5%, and PP is not easy to form charcoal during combustion, accompanied by a large number of molten droplets, which...
