Abstract
The invention relates to a preparation method of a composite flame-retardant material. The preparation method comprises the following steps of 1, taking 68 parts by weight of polyimide, and crushing the polyimide into polyimide particles having the diameter less than 5mm by a crusher, 2, uniformly mixing the polyimide particles and 30 parts by weight of vermiculite, and adding 2 parts by weight of tubular graphite into the mixture, and 3, heating the mixture obtained by the step 2 until partial fusion, and cooling to obtain the polyimide composite flame-retardant material. Through utilization of vermiculite in polyimide, polyimide flame retardation is effectively improved. Through utilization of tubular graphite, composite material flame retardation is not influenced and can be improved. The preparation method has simple processes. The composite flame-retardant material obtained by the preparation method has good flame retardation.
Description
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 polyimide composite flame-proof 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 polyimide composite flame-proof material
The present invention is achieved in that
A kind of preparation method of composite flame-proof material comprises the steps:
Step 1, get the polyimide of 68 weight parts, make diameter less than the polyimide particles of 5mm by crusher;
Step 2, the vermiculite of polyimide particles and 30 weight parts is mixed after, add the tubular graphene of 2 weight parts;
Step 3, miscellany is heated to partial melting after, the cooling polyimide composite flame-proof material that namely makes.
The present invention can effectively improve the flame retardant properties of polyimide by add vermiculite in polyimide, and the tubular graphene 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.
