Problems solved by technology

However, carbon black is expensive and difficult to disperse, high energy consumption and polluting the environment
Moreover, if the particle size is too small and the specific surface area is too large, the surface energy is extremely large, and it is easy to agglomerate, which belongs to excess function
Not only affect the use effect, but also increase the cost

Embodiment 3

[0103] Example 3: PVC black cable sheathing material.

[0104] 100 parts polyvinyl chloride

[0105] 65 parts plasticizer

[0106] Lead salt stabilizer 7 parts

[0107] Modified superfine coal powder (1000 mesh) 40 parts

[0108] 1 part paraffin

[0109] 3 parts antimony trioxide

[0110] The above-mentioned materials are weighed and added to a high-speed mixer for kneading, discharged after 12 minutes, entered into a twin-screw extruder for granulation, and then cooled to obtain the finished product. Its performance can reach the national standard GB / T 8815-2002: "soft polyvinyl chloride plastics for wire and cable".

[0111] In Examples 1 to 3, 2 to 7 parts of stabilizers and plasticizers (including dioctyl esters, dibutyl esters, acetyl citrate esters, epoxy soybean oil, etc.) are 2 to 7 parts, and the fineness above 800 mesh Adding 90 parts of modified superfine coal powder has a slight decrease in performance, but still meets the relevant standards.

Abstract

The invention relates to modified refined coal compound plastic. It includes plastic 100 portions, polyvinyl chloride and the matched plasticizer 1-95 portions, stabilizer 2-7 portions; plastic 100 portions and polyethylene, polypropylene, ethane acetic acid ethylene copolymer, polystyrene or ABS, and bulk additive 5-90 portions. The physical and chemical indexes are: carbon content >=90%, 18um screenings <=1%, dispersant and coupling agent 0.5-6 portions. The parent material carbon content of the invention could be over 70%. When being used in polyethylene and polyvinyl chloride cable material, it could make cable material ageing resistance, reinforcing action and equally black.

Description

technical field [0001] The invention belongs to components and formulations of composite materials, especially the formulation and application of modified superfine coal powder composite plastics. Background technique [0002] CN86102709 The formula of polypropylene matrix resin is a formula of polypropylene matrix resin, which contains polypropylene matrix resin and carbon black. The amount of carbon black is equivalent to 0.01-0.6% of the weight of polypropylene matrix resin. The resin formula is suitable for the production of paint with excellent paint Performance molded products. [0003] CN88105121.7 Nylon reinforced cable trough provides a nylon reinforced cable trough for laying underground cables in railway telecommunication systems. The composition and weight percentage distribution ratio of the material for making this cable trough is: polyethylene 35-45; polypropylene 15-26; aging nylon cord 13-28; talcum powder 10; stone powder 10; carbon black 3.
