Description

One kind mixes graphene, carbon fiber and boron nitride nanosheet 3D printing modified ABS material And preparation method thereof
Technical field
The invention belongs to 3D printing technique field, and in particular to one kind mixes graphene, carbon fiber and boron nitride nanosheet 3D Printing modified ABS material and preparation method thereof.
Background technology
3D printing (3DP) is one kind of rapid shaping technique, and it is a kind of based on mathematical model file, with powder Shape metal or plastics etc. can jointing material, come the technology of constructed object by way of successively printing.
3D printing is typically what is realized using digital technology file printing machine.Often in the neck such as Making mold, industrial design Domain is used for modeling, after be gradually available for the direct manufactures of some products, had zero printed using this technology Part.The technology is in jewelry, footwear, industrial design, building, engineering and construction (AEC), automobile, Aero-Space, dentistry and medical treatment Industry, education, GIS-Geographic Information System, civil engineering, gun and other field have all been applied.
3D printing has many different technologies.Their difference is in the way of available material, and with Different layer building establishment portion parts.3D printing common used material has nylon glass, PLA, ABS resin, durability nylon material, stone Cream material, aluminum, titanium alloy, stainless steel, silver-plated, gold-plated, rubber type of material.
Wherein, ABS resin is to be used for the material of fused glass pellet (FDM) technology earliest, and the print temperature of the material is 210-260 DEG C, glass transition temperature is 105 DEG C, and it has lot of advantages, and such as intensity is higher, and toughness is preferable, impact resistance, absolutely Edge number, it is anticorrosive, it is low temperature resistant, but heating is needed during ABS printings, while the material contract on cooling is it is obvious that easily go out The quality problems such as existing warpage, cracking.
The content of the invention
An object of the present invention is simple there is provided a kind of preparation method in view of the shortcomings of the prior art, prepares Modified ABS material excellent performance the preparation for mixing graphene, carbon fiber and boron nitride nanosheet 3D printing modified ABS material Method.
An object of the present invention is to be less prone to warpage there is provided one kind in view of the shortcomings of the prior art, ftractureed, to the cold What shrinkage significantly improved mixes graphene, carbon fiber and boron nitride nanosheet 3D printing modified ABS material.
Technical program of the present invention lies in provide one kind to mix graphene, carbon fiber and boron nitride nanosheet 3D printing modification The preparation method of ABS material, it is characterised in that the preparation method is to mix dried SBS and ABS with surfactant Uniformly；Then glass fibre and graphene, carbon fiber and boron nitride nanosheet are added, mixing, Screw Extrusion after heating is done It is dry, obtain modified ABS material.
The present invention further comprises following preferred technical scheme：
It is preferred that scheme in, SBS and ABS mass ratio is 1-5：5-10.
SBS and ABS mass ratio is more preferably 2-4：6-8.
It is preferred that scheme in, with respect to 100 mass parts ABS, the addition of boron nitride nanosheet is 1-5 parts.
It is preferred that scheme in, with respect to 100 mass parts ABS, the addition of graphene nanometer sheet is 1-5 parts.
It is preferred that scheme in, with respect to 100 mass parts ABS, the addition of carbon fiber nanometer piece is 1-5 parts.
It is preferred that scheme in, with respect to 100 mass parts ABS, the amount of glass fibre is 5-20 parts.
It is preferred that scheme in, with respect to 100 mass parts ABS, the amount of glass fibre is 5-10 parts.
It is preferred that scheme in, the glass fibre be nano-grade glass fibre, its a diameter of 10-100nm.
It is preferred that scheme in, with respect to 100 mass parts ABS, the addition of the surfactant is 1-5 parts.
It is preferred that scheme in, the heating-up temperature be 150-250 DEG C.
The drying temperature is preferably 50-80 DEG C, and drying mode is vacuum drying.
Above-mentioned preparation method is preparation-obtained to mix graphene, carbon fiber and boron nitride nanosheet 3D printing modified ABS Material.
Compared with prior art, the advantage of the invention is that：
1st, in 3D printing ABS material, simple addition glass fibre easily easily causes anisotropic, makes the heat transfer of material Ability is uneven.And be usually that point is contacted between fiber and fiber, it is unfavorable for heat transmission.Add a certain proportion of high heat conduction stone Black alkene, carbon fiber and boron nitride nanosheet, nanometer sheet are wrapped in fiber surface, and line-face contact is presented, enhances in composite The passage of heat in portion, simultaneously because the high-specific surface area of nano material, moreover it is possible to the interfacial adhesion between reinforcer and ABS matrixes Power, reduces the interface resistance of composite inner.
2nd, by the combination of SBS+ABS+ glass fibres+graphene, carbon fiber and boron nitride nanosheet, not only greatly reduce Usage amount needed for glass fibre, and largely improve the performance of ABS material.
3rd, warpage, cracking phenomena are largely reduced.
4th, contract on cooling performance significantly improves.
