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

The preparation method of polypropylene composite materials fire retardant material

Technical field

The present invention relates to a kind of preparation method of fire retardant material, particularly relate to a kind of preparation method of polypropylene composite materials fire retardant material.

Background technology

In modern handle official bussiness and place, house, a lot of materials are all inflammable materials.Due to the uncertainty of fire, in the time of presence of fire, a lot of materials can burn, and produce a large amount of heats on the one hand, and main is that a lot of materials can send toxic gas and flue dust, thereby has increased the hazardness of fire.

In order to reduce the harm of fire, a lot of fire retardant materials are arranged in test or use, but a lot of fire retardant materials faces that cost is high, flame retardant effect is poor at present, low etc. the problem of physical strength, and the application of fire retardant material is restricted.

Summary of the invention

The object of the present invention is to provide a kind of good flame retardation effect, prepare the preparation method of simple polypropylene composite materials fire retardant material

The present invention is achieved in that

A kind of preparation method of polypropylene composite materials fire retardant material comprises the steps:

Step 1, get the polypropylene of 45 weight parts, make diameter less than the polypropylene GRANULES of 5mm by crusher;

Step 2, the polyorganosilicate MMT of polypropylene GRANULES and 50 weight parts is mixed after, add the aluminium hydroxide of 5 weight parts;

Step 3, miscellany is heated to partial melting after, the cooling polypropylene composite materials fire retardant material that namely makes.

The present invention can effectively improve polyacrylic flame retardant properties by add polyorganosilicate in polypropylene, and the aluminium hydroxide that adds in addition neither affects the flame retardant effect of matrix material, can improve flame retardant effect again.Has method simple, the advantages such as good flame retardation effect.
