Description
Technical Field
The invention relates to the technical field of alloy materials, in particular to an antistatic high-strength ABS modified material and a preparation method thereof.
Background
For metal products, plastic products have the advantages of light specific gravity, recycling, environmental protection, excellent strength and the like, but the conductivity is poorer than that of metals, so that the plastic products are easy to electrostatically adsorb, can adsorb some small molecular pollutants, dust and the like, influence the use and quality of the products, and seriously possibly cause disasters such as fire disasters and the like. Therefore, antistatic modification of plastic materials is becoming a need of the industry. At present, common additives on the market are antistatic agents which are long-acting and short-acting and are modified according to different actual requirements, but the effect of the antistatic agent can only reach the surface resistivity of 108～109On the other hand, if the requirements are higher, other modification aids are required to be added for improvement, for example, the more common conductive carbon black is used, and the surface resistivity of the general material can reach 102～104Left and right, close to copper material. However, the conductive carbon black is an inorganic filler, when the addition amount is increased, the strength of the conductive carbon black is obviously reduced, the material shows obvious brittleness, and simultaneously, the carbon black has a high oil absorption value, is difficult to disperse in the material, causes difficult processing, is difficult to produce a modified conductive material with an ideal effect, has unstable surface resistivity, and cannot be practically produced and adopted in industrialized products.
Disclosure of Invention
The invention aims to overcome the technical problems and provides an antistatic high-strength ABS modified material.
The invention also provides a preparation method of the antistatic high-strength ABS modified material.
In order to achieve the purpose, the invention adopts the following technical scheme: an antistatic high-strength ABS modified material comprises the following components in parts by weight:
30-70 parts of acrylonitrile-butadiene-styrene copolymer, 20-40 parts of polycarbonate, 5-20 parts of methyl methacrylate-butadiene-styrene copolymer, 2-5 parts of modified glass fiber, 6-10 parts of carbon nano tube, 2-6 parts of conductive carbon black, 3-6 parts of dispersing agent and 1-2 parts of antioxidant.
The acrylonitrile-butadiene-styrene copolymer has good mechanical strength, chemical resistance, corrosion resistance, impact resistance and dimensional stability. The resistivity of the conductive carbon black can reach 102～104And the material is similar to copper material, and can improve the antistatic performance of the material. The inventor researches and discovers that the strength of the material is obviously reduced and the material shows obvious brittleness as the adding amount of the conductive carbon black is increased because the conductive carbon black is the inorganic filler. The invention uses the carbon nano tube and the conductive carbon black to improve the surface resistivity of the material and reduce the consumption of the conductive carbon black, and simultaneously adopts the polycarbonate, the methyl methacrylate-butadiene-styrene copolymer and the modified glass fiber to improve the problem of low impact resistance and the impact strength, thereby obtaining the ABS modified material with high strength and antistatic property. The high-efficiency dispersant and the antioxidant are added to improve the processing performance and prolong the service life of the material.
Preferably, the preparation method of the modified glass fiber comprises the following steps:
ultrasonically dispersing glass fiber in deionized water, heating to 45-50 ℃ in a water bath, dropwise adding an ethanol solution of tetra-n-butyl titanate under the stirring condition, reacting for 4-8h, centrifugally separating, washing and drying to obtain composite fiber; adding the composite fiber into deionized water, performing ultrasonic dispersion uniformly, heating to 60-70 ℃, dropwise adding hydrochloric acid mixed solution of stannic chloride and antimony trichloride under the stirring condition, adjusting the pH to 2-3, reacting for 2-3h, performing centrifugal separation, washing, drying, and calcining in a muffle furnace at 350-400 ℃ for 3-5h to obtain the modified glass fiber.
As the conductive carbon black can cause the reduction of the impact strength of the ABS material, the invention enhances the impact resistance of the ABS material by reducing the dosage of the conductive carbon black and adding the modified glass fiber. Titanium dioxide nanoparticles generated after hydrolysis of tetrabutyl titanate by a sol-gel method are deposited on the surface of the glass fiber, and a punctate convex structure is formed on the surface of the glass fiber, so that the roughness of the surface of the glass fiber is increased, the resin and the glass fiber are combined more tightly, and the impact resistance of the antistatic ABS material is obviously enhanced. In the research of the inventor, the glass fiber can improve the strength of the ABS material, but the glass fiber influences the resistivity of the ABS material and reduces the antistatic performance, and aiming at the problem, the invention deposits a tin oxide thin layer with good conductivity on the surface of the glass fiber, and antimony oxide is doped in the tin oxide, so that the negative influence of the glass fiber on the antistatic performance of the ABS material is avoided.
Preferably, the mass ratio of the tin tetrachloride to the composite fiber is 1: 10-15.
In the experimental process, researches find that the mass ratio of the stannic chloride to the composite fiber has important influence on the impact resistance and the antistatic property of the high ABS material. When the mass ratio of the stannic chloride to the composite fiber is lower than 1:15, and the amount of the stannic chloride is insufficient, the stannic oxide deposited on the surface of the composite fiber is not enough to form a thin layer to cover the composite fiber, so that the conductivity of the composite fiber is influenced, and the antistatic property of the ABS material is further influenced; when the mass ratio of the tin tetrachloride to the composite fiber is higher than 1:15, the tin tetrachloride is excessive, the tin oxide layer deposited on the surface of the composite fiber is too thick, and the titanium dioxide protruding structure on the surface of the glass fiber is completely covered, so that the protruding structure on the surface of the glass fiber disappears, the roughness of the surface of the glass fiber is reduced, the bonding strength of the glass fiber and resin is reduced, and the impact resistance of the ABS material is reduced. The mass ratio of the tin tetrachloride to the composite fiber is controlled to be 1:10-15, so that the reinforcing effect of the glass fiber on the ABS material is maintained, the resistivity of the glass fiber is improved, and the weakening of the antistatic effect of the ABS material caused by the glass fiber is avoided.
Preferably, the tube diameter of the carbon nano tube is 10-20nm, and the length of the carbon nano tube is 3-15 nm.
Preferably, the DBP absorption value of the conductive carbon black is 380-460Ml/100 g.
Preferably, the dispersant is at least one of polysiloxane dispersant and N, N' -ethylene bisstearamide.
Preferably, the antioxidant is at least one of antioxidant 1076, antioxidant 1010 and antioxidant 168.
The preparation method of the antistatic high-strength ABS modified material comprises the following steps:
1) adding polycarbonate, carbon nano tubes, conductive carbon black and a dispersing agent into an internal mixer for mixing, uniformly mixing, then sending into a double-screw extruder for granulation, and drying to obtain PC master batches;
2) adding the PC master batch, acrylonitrile-butadiene-styrene copolymer, methyl methacrylate-butadiene-styrene copolymer, antioxidant and modified glass fiber into a stirrer, uniformly mixing, feeding the mixed material into a double-screw extruder, and carrying out melt mixing, extrusion, air drying and grain cutting to obtain the antistatic high-strength ABS modified material.
Preferably, the mixing temperature of the materials in the step 1) in the internal mixer is 260 ℃ and 270 ℃, and the mixing time is 20-30 min.
Therefore, the invention has the following beneficial effects: 1) the surface resistivity of the material is improved by using the carbon nano tube and the conductive carbon black, the using amount of the conductive carbon black is reduced, and meanwhile, the problem of low impact resistance of the material is solved by using the polycarbonate, the methyl methacrylate-butadiene-styrene copolymer and the modified glass fiber, so that the impact strength of the material is improved, and the high-strength antistatic ABS modified material is obtained; 2) titanium dioxide nanoparticles generated after hydrolysis of tetrabutyl titanate by a sol-gel method are deposited on the surface of the glass fiber, and the glass fiber forms a punctiform convex structure, so that the roughness of the surface of the glass fiber is increased, the resin and the glass fiber are more tightly combined, and the impact resistance of the glass ABS material is obviously enhanced; 3) a tin oxide thin layer with good conductivity is deposited on the surface of the glass fiber, and antimony oxide is doped in the tin oxide, so that the negative influence of the glass fiber on the antistatic performance of the ABS material is avoided.
