[0040] Further, the preparation method of described novel PME plastic comprises the following steps:

[0041] S1, send the PC masterbatch and UHMWPE ultra-high molecular polyethylene into a vacuum drying oven respectively, and dry them in vacuum. Hourly rise 7°C until the temperature reaches 118°C, then send the dried PC masterbatch and UHMWPE ultra-high molecular polyethylene into the heating box, the heating temperature is 90°C ~ 93°C, after baking for 4.5h ~ 5h , take out the spare;

[0042] S2, Put the baked PC masterbatch, UHMWPE ultra-high molecular polyethylene and other raw materials into a high-speed mixer for mixing treatment to obtain a mixture. The temperature of the mixing treatment is 140 ° C ~ 145 ° C, and the duration of the mixing treatment is 18 minutes ~23min, put the mixture into the reaction kettle, seal it and replace it with nitrogen gas for 8~9 times, heat to react, the reaction pressure is 3.0MPa~3.1MPa, the reaction temperature is 210℃~218℃, and the ...

Embodiment example 1

[0062] Calcium carbonate, glycerin, hydroxypropyl methylcellulose ether, diatomaceous earth, propylene glycol and xylitol are mixed according to the mass ratio of 3:2:1:2:1:3 to make plastic additives, and then carbon black, Carbon fiber and medium-alkali glass fiber are mixed according to the mass ratio of 1:1:2 to make antistatic agent;

[0063] Add pentane solvent to the reaction kettle, then add 130 parts of propylene, 7 parts of triethylaluminum and 13.5 parts of methylalumoxane in sequence, stir evenly, and then continuously feed ethylene to carry out one-stage polymerization reaction. The temperature of one-stage polymerization reaction is 100°C, pressure 2.5MPa, time 4.5h, the product obtained from the first-stage polymerization reaction and 55 parts of 1-butene, 10 parts of nano-metal powder and 3 parts of fluorescent powder were subjected to a second-stage polymerization reaction, and the temperature of the second-stage polymerization reaction was 90°C , pressure 1.8...

Abstract

The invention relates to the technical field of PME plastics, in particular to a novel PME plastic which comprises PC master batch, UHMWPE ultra-high molecular weight polyethylene, a plastic additive, a composite flame retardant and an antistatic agent, and is specifically prepared from the following components in parts by weight: 90 to 110 parts of the PC master batch, 10 to 60 parts of the UHMWPE, 10 to 20 parts of the plastic additive, 10 to 15 parts of the composite flame retardant and 10 to 15 parts of the antistatic agent. According to the design, the problems that the flame retardant property and the antistatic property of the existing PME plastic are relatively weak, and the application range is limited are effectively solved.

Description

technical field [0001] The invention relates to the technical field of PME plastics, in particular to a novel PME plastic. Background technique [0002] PME plastic is prepared by mixing PC fabric and UHMWPE ultra-high molecular polyethylene, which has good wear resistance and self-lubricating properties. [0003] At present, the flame retardant and antistatic properties of PME plastics are weak, and the scope of application is limited. [0004] In summary, the present invention solves the existing problems by designing a new type of PME plastic. Contents of the invention [0005] The object of the present invention is to provide a kind of novel PME plastics, to solve the problem that proposes in the above-mentioned background technology. [0006] To achieve the above object, the present invention provides the following technical solutions: [0007] A new type of PME plastic, including PC masterbatch, UHMWPE ultra-high molecular polyethylene, plastic additives, composit...
