Abstract

The invention relates to a preparation method of a polypropylene composite flame-retardant material. The preparation method comprises the following steps of 1, taking 45 parts by weight of polypropylene, and crushing the polypropylene into polypropylene particles having the diameter less than 5mm by a crusher, 2, uniformly mixing the polypropylene particles and 50 parts by weight of organic clay MMT, and adding 5 parts by weight of aluminum hydroxide into the mixture, and 3, heating the mixture until partial fusion, and cooling to obtain the polypropylene composite flame-retardant material. Through utilization of the organic clay MMT in polypropylene, polypropylene flame-retardant performances are improved effectively. Through utilization of aluminum hydroxide, composite material flame retardation is not influenced and can be improved. The preparation method has simple processes. The polypropylene composite flame-retardant material obtained by the preparation method has good flame retardation.

Description

technical field

[0001] The invention relates to a preparation method of a flame retardant material, in particular to a preparation method of a polypropylene composite flame retardant material. Background technique

[0002] In modern offices and homes, many materials are flammable. Due to the uncertainty of fire, when a fire occurs, many materials will burn. On the one hand, a lot of heat is generated, and more importantly, many materials will emit toxic gases and smoke, which increases the hazard of fire.

[0003] In order to reduce the hazards of fire, many flame retardant materials have been tested or used, but many flame retardant materials currently face problems such as high cost, poor flame retardant effect, and low mechanical strength, which limit the application of flame retardant materials. SUMMARY OF THE INVENTION

[0004] The object of the present invention is to provide a preparation method of polypropylene composite flame retardant material with good flame re...

Examples

Embodiment 1

[0012] A preparation method of polypropylene composite flame retardant material, comprising the following steps:

[0013] Step 1, take 45 parts by weight of polypropylene, and form polypropylene particles with a diameter of less than 5mm by a crusher;

[0014] Step 2, after mixing the polypropylene particles with 50 parts by weight of organoclay MMT, add 5 parts by weight of aluminum hydroxide;

[0015] Step 3: After the mixture is heated to a partial melting point, the polypropylene composite flame retardant material is obtained by cooling.
