Antistatic flame-retardant polypropylene material and preparation method thereof

Abstract

The invention discloses an antistatic flame-retardant polypropylene material which is prepared from the following raw materials in parts by weight: 78 parts of PP resin, 10 parts of an antistatic agent, 10 parts of POE resin, 0.1 part of PETS, 0.2 part of diffusion oil, 1.2 parts of zinc stearate, 0.8 part of an antioxidant, 15 parts of a filling agent, 3 parts of an impact modifier, 3 parts of aflame retardant, 0.1 part of a slipping agent and 0.3 part of pigment powder, wherein the antistatic agent comprises an antistatic agent H95 and an antistatic agent 3500 in a weight ratio of 3:1; theantioxidant comprises an antioxidant 712 and an antioxidant RC 1726 in a weight ratio of 1:3; the filling agent is nanometer calcium carbonate with the particle diameter of 5 nm; the flame retardant comprises dibromoneopentyl glycol and melamine in a weight ratio of 1:2; and the slipping agent comprises stearamide and tri-octadecyl ester citrate in a weight ratio of 3:1. Compared with the prior art, the antistatic effect of the polypropylene material is greatly improved, and the impact strength, heat distortion temperature, tensile strength and flame retardancy are improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an antistatic flame retardant polypropylene material and a preparation method thereof. Background technique [0002] Flame retardant and antistatic polypropylene is widely used in mining, chemical industry, oil and gas transportation and other fields due to its excellent flame retardant and antistatic properties. Since the polypropylene material itself is a flammable and insulating material, the usual method is to add a certain amount of flame retardant and antistatic agent to the system to meet the flame retardant and antistatic performance requirements of its products, but the use of a large number of additives It will cause a significant decline in the mechanical properties of the polypropylene material itself, such as toughness. [0003] In the production process of polypropylene plastic, in order to improve the corresponding functions, flame retardants, antistatic...

Problems solved by technology

If more functional improvers are added, the mechanism will be more complicated and difficult to predict and deduce

[0004] At present, the prior art has disclosed some technical solutions of antistatic and flame retardant polypropylene materials. Although these polypropylene materials have excellent antistatic effect and the surface resistivity reaches 5-8 orders of magnitude, the comprehensive performance including antistatic There is still room for continuous improvement in performance, such as impact strength, heat distortion temperature, tensile strength, etc.
