preparation example Construction

[0051] A method for preparing a high-rigidity and high-toughness polypropylene antistatic composite material as described above comprises the following steps:

[0052] Step 1, dispersing the nano-reinforcing agent in ethanol with a high-speed mixer to obtain a nano-reinforcing agent dispersion;

[0053] Step 2: Coupling the talc powder with a coupling agent in a high-speed mixer for 5-10 minutes, then adding the nano-enhancement agent dispersion liquid and stirring at a high speed, and making the temperature in the mixer gradually reach 70-80 degrees, and the stirring time is 20-30 minutes. Use pulse filter bag exhaust to make more than 90% of ethanol volatilize from the material;

[0054] Step 3. Put homopolymerized PP, copolymerized PP, compatibilizer, toughening agent and other additives into the mixer and mix for 5-10 minutes, then feed the material into the main feed of the extruder; The side of the cylinder is fed and added.

[0055] Step 4. Extrude the material.

Abstract

The invention discloses a high rigidity high toughness polypropylene anti-static composite material and a preparation method thereof. In the prior art, the cost of the materials of a thin-wall light anti-static turnover box, a foldable anti-static turnover box, and an anti-static turnover car chassis with a large load capacity is high, and the performance of the materials is not good. In order tosolve the problems mentioned above, the invention provides a high rigidity high toughness polypropylene anti-static composite material. The cost of the composite material is low. The composite material can be easily applied to industrial production and application, and is an ideal material for producing a thin-wall light anti-static turnover box, a foldable anti-static turnover box, and an anti-static turnover car chassis with a large load capacity.

Description

technical field [0001] The invention relates to composite materials for injection molding light weight anti-static turnover boxes, foldable anti-static turnover boxes, high-load anti-static turnover vehicles, etc., and belongs to materials used in the fields of electronics and military industry. Background technique [0002] Polypropylene is currently the most cost-effective thermoplastic resin. It has the advantages of light specific gravity, flexible molecular chain, high thermal decomposition temperature, wide processing temperature window, and strong chemical inertness. It is an ideal resin for composite materials. At present, the anti-static turnover boxes in China are all one-piece design, and the transportation cost is high; in addition, because the carbon black and other fillers that endow polypropylene with anti-static properties greatly reduce its strength and toughness, the walls of the popular anti-static turnover boxes on the market It is thicker and more cumber...
