Embodiment 1

[0028] A montmorillonite composite flame retardant material, comprising the following components by weight:

[0029] 60 parts of polypropylene resin, 1 part of modified montmorillonite, 2 parts of phosphorus-containing flame retardant, 1 part of flame retardant synergist, 1 part of compatibilizer and 0.1 part of antioxidant.

[0030] Wherein, modified montmorillonite is prepared by the following method:

[0031] Add montmorillonite to 90°C water, ultrasonically disperse for 0.5h to prepare a montmorillonite dispersion with a concentration of 5wt%, then add intercalation agent and protonating agent, control the temperature to 90°C, continue ultrasonically dispersing for 0.5h, then Filter to get the first precipitate, put the first precipitate in a beaker, add 90°C water, stir for 0.5h, filter to get the second precipitate, put the second precipitate in a beaker, add 90°C water, stir for 0.5h, Filter to obtain the third precipitate, put the third precipitate in a beaker, add 90...

Embodiment 2

[0037] A montmorillonite composite flame retardant material, comprising the following components by weight:

[0038] 80 parts of polypropylene resin, 3 parts of modified montmorillonite, 5 parts of phosphorus-containing flame retardant, 2 parts of flame retardant synergist, 5 parts of compatibilizer and 0.5 part of antioxidant.

[0039] Wherein, modified montmorillonite is prepared by the following method:

[0040] Add montmorillonite to water at 80°C, ultrasonically disperse for 1 hour to obtain a montmorillonite dispersion with a concentration of 10 wt%, then add intercalation agent and protonating agent, control the temperature at 80°C, continue ultrasonically dispersing for 1 hour, and then filter. To obtain the first precipitate, put the first precipitate in a beaker, add 80°C water, stir for 0.5h, filter to obtain the second precipitate, put the second precipitate in a beaker, add 80°C water, stir for 0.5h, filter, To obtain the third precipitate, put the third precipit...

Embodiment 3

[0046] A montmorillonite composite flame retardant material, comprising the following components by weight:

[0047] 65 parts of polypropylene resin, 1.5 parts of modified montmorillonite, 3 parts of phosphorus-containing flame retardant, 1.3 parts of flame retardant synergist, 2 parts of compatibilizer and 0.2 part of antioxidant.

[0048] Wherein, modified montmorillonite is prepared by the following method:

[0049]Add montmorillonite to water at 80°C, ultrasonically disperse for 1 hour to obtain a montmorillonite dispersion with a concentration of 6 wt%, then add intercalation agent and protonating agent, control the temperature at 80°C, continue ultrasonic dispersion for 1 hour, and then filter. To obtain the first precipitate, put the first precipitate in a beaker, add 80°C water, stir for 0.5h, filter to obtain the second precipitate, put the second precipitate in a beaker, add 80°C water, stir for 0.5h, filter, To obtain the third precipitate, put the third precipitat...

Abstract

A montmorillonite composite flame retardant material and a preparing method thereof are disclosed. The montmorillonite composite flame retardant material includes, by weight, 60-80 parts of polypropylene resin, 1-3 parts of modified montmorillonite, 2-5 parts of a phosphorus containing flame retardant, 1-2 parts of a flame retardant synergistic, 1-5 parts of a compatilizer and 0.1-0.5 part of an antioxidant. Through specific component composition, the components are synergistic. The montmorillonite composite flame retardant material does not generate toxic or harmful gas after combustion, is free of harm to human bodies and is free of environment pollution. A preparing process is simple and convenient, the cost is low and the method is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of composite flame-retardant materials, and in particular relates to a montmorillonite composite flame-retardant material and a preparation method thereof. Background technique [0002] Polypropylene (Polypropylene, abbreviated as PP), as a light weight, non-toxic, cheap general-purpose plastic, has a wide range of sources, low density, good mechanical properties, excellent insulation properties, stress resistance, corrosion resistance, and easy processing and molding. Advantages, widely used in electrical appliances, chemicals, machinery, prevention, food packaging and other industries. Since polypropylene is a hydrocarbon material, its oxygen index is only 17.4-18.5%. It is flammable and burns fast, and produces a large number of molten droplets during combustion, which can easily spread flames and bring many hidden dangers to people's production and life. In order to overcome this shortcoming, people oft...
