Description

Technical Field

[0001] The invention belongs to the technical field of polypropylene composites, and in particular relates to an antistatic PP composite material based on high-gloss carbon black and a preparation method thereof. Background Art

[0002] As an important thermoplastic, polypropylene (PP) material has been widely used in various industries due to its excellent chemical stability and cost-effectiveness. In the field of composite materials and decoration, polypropylene is particularly favored due to its light weight, dimensional stability and chemical corrosion resistance.

[0003] However, pure polypropylene material has poor antistatic properties and is prone to static electricity accumulation under certain circumstances, which limits its application in certain static-sensitive applications, especially in finishing materials, where static electricity can easily absorb dust in the air, resulting in insufficient aesthetics of the finish.

[0004] In order to overcome the above problems, various methods including adding conductive fillers are used in the prior art to reduce the electrostatic properties of polypropylene materials. Among them, carbon black, as an ideal conductive filler, has a significant effect in long-term antistatic performance due to its extremely high conductivity and low cost. However, carbon black particles have a complex porous structure and a surface area with many defects, which not only enables them to effectively absorb or scatter light, but also causes the glossiness of the surface of the polypropylene material to decrease, causing the polypropylene products to lose transparency and smooth appearance, which significantly limits its application in fields with high requirements for decorativeness and gloss. Summary of the invention

[0005] In order to solve the technical problems mentioned in the background technology, the object of the present invention is to provide an antistatic PP composite material based on high gloss carbon black and a preparation method thereof.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] An antistatic PP composite material based on high-gloss carbon black comprises the following raw materials in parts by weight: 100 parts of PP resin, 15-20 parts of POE resin, 8.5-12 parts of high-gloss carbon black, 0.6-0.8 parts of antistatic additive, 10-15 parts of filler, 2.5-3.5 parts of lubricant and 0.12-0.15 parts of antioxidant.

[0008] The high gloss carbon black is prepared by the following method:

[0009] Step A1: Preheat pentaerythritol tetraacrylate, p-hydroxythiophenol and ethyl acetate to dissolve, introduce nitrogen protection, then add photoinitiator and mix well, then control the temperature to 55-70°C, use 150-220W / m 2UV irradiation, stirring at 90-120 rpm for 2.5-3.5 hours, removing ethyl acetate after the reaction is completed to obtain a surface modifier;

[0010] Furthermore, the feed ratio of pentaerythritol tetraacrylate, p-hydroxythiophenol, photoinitiator and ethyl acetate is 10mmol:40mmol:6-10mg:80-110mL. Under ultraviolet initiation, the active thiophenol structure of p-hydroxythiophenol and the terminal double bond of pentaerythritol tetraacrylate are click-added to introduce terminal phenol structure modification.

[0013] Furthermore, the feed ratio of the conductive carbon black, the surface modifier and the acetone is 50g:3.2-4.4g:270-350mL, the molecular weight of the surface modifier is relatively high, and the molecule contains a large number of benzene ring structures, and the porous structure on the surface of the conductive carbon black has a strong adsorption effect, and the surface modifier is adsorbed and loaded onto the surface pore wall of the conductive carbon black to form a composite modification;

[0014] Preferably, the average particle size of the conductive carbon black is 30-50 nm. Within this particle size range, the carbon black is easily dispersed and colored and forms a continuous conductive network. At the same time, it has good adsorption properties and can effectively load the surface modifier in the gaps.

[0015] Step A3: The modified carbon black, aniline and tetrahydrofuran are stirred and dispersed, and then hydrochloric acid is added and mixed. The temperature of the water bath is controlled at 40-60° C., and ammonium persulfate solution is slowly added to react for 3.5-5.5 hours. After the reaction is completed, the precipitate is centrifuged and washed with water until neutral and dried to obtain high gloss carbon black;

[0016] Furthermore, the feed ratio of modified carbon black, aniline, ammonium persulfate, hydrochloric acid and tetrahydrofuran is 50g:7.8-9.5g:1.2-1.8g:300-400mL:70-90mL. The surface modifier molecules adsorbed on the surface of the modified carbon black contain a large number of ester groups and phenolic hydroxyl groups, which produce hydrogen bonds with aniline, enriching aniline in the surface voids of the modified carbon black, and the phenolic hydroxyl groups provide protons to protonate the aniline molecules in the voids, preferentially starting the polymerization process, and forming polyaniline filling in the carbon black voids.

[0017] Preferably, the antistatic auxiliary agent is selected from anionic antistatic agents to synergistically reduce the surface resistance of the composite material.
