Embodiment 1

[0041] The plant raw material used in this embodiment is corncob.

[0042] Send the plant material into a microwave vacuum tank, vacuumize until the vacuum degree is -0.02MPa, and then perform microwave treatment, the microwave frequency is 300MHz, and the microwave treatment time is 1min;

[0043] The plant raw materials obtained through pretreatment are dried, pre-carbonized, carbonized, calcined, and cooled in sequence. The temperature at each temperature measurement point is 150°C in drying area A, 275°C in pre-carbonization area B, and 450°C in carbonization area C. Observation during warming figure 1 The zone D shown is the temperature of different positions in the combustion zone. When the temperature of a certain place in the combustion zone, such as d2, is too low, open the small hole in that place, introduce air and burn it nearby, so as to raise the temperature in this place and control the bamboo to move down. The temperature of the combustion zone experienced in ...

Abstract

The invention relates to the field of polymers, and in particular relates to a production method of vegetable carbon plastics. The method comprises the following steps in sequence: feeding the raw vegetables into a microwave vacuum tank to undergo microwave treatment; drying, pre-carbonizing, carbonizing, calcining and cooling the pretreated raw vegetables in sequence; controlling combustion to raise the temperature to 700-750 DEG C or 900-1000 DEG C at a rate of 5-15 DEG C / min and maintaining the temperature for 40-80 minutes; then raising the temperature to 1000-1500 DEG C or 1600-1800 DEG C at a rate of 5-15 DEG C / min and maintaining the temperature for 2-8 hours to obtain vegetable carbon; and blending and modifying the base materials such as ultra-high molecular weight polyethylene with molecular weight of 4-7 million and high-density polypropylene with molecular weight of 1-1.4 million and adding a flame retardant, a toughening agent, a coupling agent, an antioxidant and the obtained vegetable carbon in the processing course. The prepared vegetable carbon plastics have the advantages of excellent toughness, higher rigidity and hardness and good antistatic property and flame retardance.

Description

technical field [0001] The invention relates to the field of macromolecules, in particular to a production method of plant charcoal plastics. Background technique [0002] Ultra-high molecular weight polyethylene (UHMWPE) refers to polyethylene with a relative molecular weight of more than 1.5 million. It is a new type of engineering plastic with the best comprehensive performance among current engineering plastics. The molecular structure arrangement of ultra-high molecular weight polyethylene is exactly the same as that of ordinary polyethylene, but because of its very high relative molecular weight, it has many excellent properties that ordinary polyethylene materials do not have. For example: it has ① not easy to adhere to foreign matter; ② chemical corrosion resistance; ③ non-toxic, recyclable and so on. [0003] Although ultra-high molecular weight polyethylene has the above advantages, it also has disadvantages, such as poor temperature resistance (heat distortion te...
