Embodiment 1

[0018] Embodiment 1: the preparation of plant extract

[0019] Take the leaves of Lemon Eucalyptus, Eucalyptus microphyllum, Eucalyptus microphyllum, Candelabra, Red sea olive, and Mint in equal amounts, totaling 7 catties, crush them, add 20 catties of water, heat to boiling, distill for 1 hour with a wine distillation device, and collect the oil to obtain The plant extract, detected by HP6890GC / HP5973 MS, is composed of 9.26% α-pinene, 1.12% β-pinene, 3.95% p-cymene, 35.03% 1,8-eucalyptus by mass fraction Brain, 0.15% γ-terpene, 50.21% methyl salicylate, 0.28% carvrene; sprinkle it on top of Styrofoam, and the Styrofoam immediately dissolves into much smaller plastic pellets or plastic block.

Embodiment 2

[0020] Embodiment 2: the preparation of plant extract

[0021] Take the leaves of Lemon Eucalyptus, Eucalyptus microphylla, Eucalyptus microphyllum, Candelabra, Red sea olive, and mint in equal amounts, totaling 7 catties, crush them, add 20 catties of water, heat to boiling, distill for 90 minutes with a wine steaming device, and collect the oil to obtain The plant extract is detected by HP6890GC / HP5973 MS, and its composition is calculated by mass fraction as 3% α-pinene, 0.5% β-pinene, 0.5% p-cymene, 20% 1,8-eucalyptus Brain, 3% gamma-terpene, 70% methyl salicylate, 3% carvrene; sprinkle it on top of Styrofoam, and the Styrofoam immediately dissolves into much smaller plastic pellets or plastic block.

Embodiment 3

[0022] Embodiment 3: the preparation of plant extract

[0023] Take the leaves of Lemon Eucalyptus, Eucalyptus microphyllum, Eucalyptus microphyllum, Candela mellifera, and mint in equal amounts, 7 catties in total, crush them, add 20 catties of water, heat to boiling, distill for 50 minutes with a wine steaming device, and collect the oil to obtain The plant extract, detected by HP6890GC / HP5973 MS, is composed of 15% α-pinene, 2.98% β-pinene, 8% p-cymene, 45% 1,8-eucalyptus by mass fraction Brain, 0.01% gamma-terpene, 29% methyl salicylate, 0.01% carvrene; sprinkle it on top of Styrofoam, and the Styrofoam immediately dissolves into much smaller plastic pellets or plastic block.

Abstract

A plant extraction used for reconditioning of cellular polystyrene and its preparation method and assemblage are disclosed. It is produced by: grinding the leaves of Eucalyptus citriodora Hook, Eucalyptus exserta F.Muell, Eucalyptus robusta Smith, kandelia candel, rhizophora stylosa, mint herb, soaking with water, distilling, collecting the oil, preparing the combination of materials adding in the accessories and the water by dispersing at high rate. Its advantages include: innocuous, contamination free, converting the huge waste cellular polystyrene into small rapidly, reclaiming and utilizing easily, volatilizing easily so as not to pollute the reclaimed waste cellular polystyrene, less dosage, low cost, conveniently using without heating and compressing, not having the cellular polystyrene analyzing, having high purity of the reclaimed product.

Description

technical field [0001] The present invention relates to a kind of plant extract used for regeneration treatment of polystyrene foam plastics and its preparation method, and also relates to the composition mainly composed of the extract, which can turn bulky waste polystyrene foam plastics into Small plastic blocks, easy to recycle, transport and reuse. Background technique [0002] Styrofoam is widely used, and waste Styrofoam causes white pollution. The main method to deal with it is the heating recovery method, which needs to establish a special device for centralized treatment, which is costly and has waste gas and waste residue emissions, and causes secondary pollution to the environment. Contents of the invention [0003] The object of the present invention is to provide a kind of material that is used for polystyrene foam regeneration treatment, make it can handle waste polystyrene foam easily again without pollution, solve the various problems of above-mentioned pr...
