Description

A kind of 3D printing modified ABS for mixing boron nitride nanosheet and aluminum nitride nanometer particle With PP materials and preparation method thereof
Technical field
The invention belongs to 3D printing technique field, and in particular to a kind of boron nitride nanosheet and aluminum nitride nanometer particle mixed 3D printing modified ABS and PP materials 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, plating aluminium nitride, 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 and PP excellent material performances the 3D printing modified ABS for mixing boron nitride nanosheet and aluminum nitride nanometer particle and The preparation method of PP materials.
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 the 3D printing modified ABS and PP materials of boron nitride nanosheet and aluminum nitride nanometer particle Material.
Technical program of the present invention lies in provide a kind of 3D printing use for mixing boron nitride nanosheet and aluminum nitride nanometer particle The preparation method of modified ABS and PP materials, it is characterised in that the preparation method is that dried PP and ABS and surface live Property agent be well mixed；Then glass fibre, boron nitride nanosheet and aluminum nitride nanometer particle, mixing, screw rod after heating are added Extrusion, dries, obtains modified ABS and PP materials.
The present invention further comprises following preferred technical scheme：
It is preferred that scheme in, PP and ABS mass ratio is 1-5：5-10.
PP 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 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, with respect to 100 mass parts ABS, the addition of aluminum nitride nanometer particle is 1-5 parts, and its particle diameter is 0.1-5nm。
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.
The preparation-obtained 3D printing modification for mixing boron nitride nanosheet and aluminum nitride nanometer particle of above-mentioned preparation method ABS and PP materials.
Compared with prior art, the advantage of the invention is that：
1st, 3D printing is with ABS and PP materials, and simple addition glass fibre 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 nitrogen Change boron nanometer sheet and aluminum nitride nanometer particle, boron nitride nanosheet and aluminum nitride nanometer particle disperse and adsorbed in fiber surface, Point-line-face contact is presented, the passage of heat of composite inner is enhanced, simultaneously because the high-specific surface area of nano material, also Interfacial adhesion between energy reinforcing fiber filler and ABS matrixes, reduces the interface resistance of composite inner.
2nd, by the combination of PP+ABS+ glass fibres+boron nitride nanosheet+aluminum nitride nanometer particle, not only greatly reduce Usage amount needed for glass fibre, and largely improve the performance of ABS and PP materials.
3rd, warpage, cracking phenomena are largely reduced.
4th, contract on cooling performance significantly improves.
5th, the yellowing phenomenon of products obtained therefrom of the present invention significantly improves.
