Method for extracting and refining rutin

A method for extracting and refining rutin comprises the following steps of (1) extraction: smashing raw materials, adding organic solvent into the smashed raw materials, performing extraction for 2-4 times, mixing extracting solution and concentrating the mixed extracting solution to thick extract with organic solvent content smaller than or equal to 5wt%; (2) alkali dissolution-acid sediment: adding alkaline water into the thick extract, then heating the mixture and stirring, filtering the heated mixture, regulating pH of alkaline filtrate to be 3-4, standing, filtering, drying to obtain a rutin pure product; and (3) mother liquor treatment: enabling obtained acid mother liquor to penetrate through a chromatographic column filled with resin, after the acid mother liquor penetrates through the chromatographic column, firstly using deionized water to wash a column bed until outflow liquid is neutral and colorless, introducing eluent into the chromatographic column and collecting eluate until outflow liquid is colorless, concentrating the eluate to the volume which is 5-10% of the original volume in a pressure reduction mode, cooling the concentrated eluate to achieve crystallization, filtering, using the deionized water to elute a filter cake, and drying the eluted filter cake to obtain a mother liquor rutin product. The prepared rutin is high in yield and purity, and the quality of the rutin reaches the international standard.

3D-nanostructure NiCo2S4 electrode material for super capacitor and preparation method thereof

The invention relates to a 3D-nanostructure NiCo2S4 electrode material and a preparation method thereof. The 3D-nanostructure NiCo2S4 electrode material is in a three-dimensional nanostructure formed through self-assembly of hexagonal NiCo2S4 nanosheets. The 3D-nanostructure NiCo2S4 electrode material is prepared through a hydrothermal method and a follow-up sulfuration process. The preparation method comprises 1) dissolving divalent cobalt salt and divalent nickel salt into an alkaline aqueous solution, and obtaining an intermediate product in a three-dimensional structure through hydrothermal reaction; and 2) dispersing the obtained intermediate product into a sulfur source solution so as to carry out hydrothermal sulfidizing processing, and thus the 3D-nanostructure NiCo2S4 electrode material can be obtained. On the basis of high seudocapacitance activity and high conductivity of the NiCo2S4 material, specific surface area is improved by forming the 3D nanostructure, and the obtained product is allowed to have excellent super capacitor performance; the hydrothermal and follow-up sulfuration processing processes are simple and are easy to operate and control; and the method is suitable for continuous large-scale production.

Preparation method of high-polymer self-adhesive waterproof roll

The invention relates to a preparation method of a high-polymer self-adhesive waterproof roll. The technical scheme is as follows: the preparation method comprises the steps of fully coating an SIS (Styrene-Isoprene-Styrene) hot melt pressure sensitive self-adhesive on a main plastic high-polymer waterproof layer by using a hot melt pressure sensitive adhesive coating machine to form an SIS hot melt pressure sensitive self-adhesive layer; then, coating an anti-adhesive isolating membrane on the pressure sensitive self-adhesive layer to prepare a high-polymer self-adhesive waterproof roll product, wherein the main plastic high-polymer waterproof layer is a high-density polyethylene cross laminated film or modified high-density polyethylene film; the anti-adhesive isolating membrane is a silicon oil coated polyurethane isolating membrane. The preparation method has the beneficial effects that firstly, the roll can be permanently and organically combined with the concrete of a structural layer due to the application of the SIS hot melt pressure sensitive self-adhesive, so that no hidden water breakthrough dangers in the intermediate process are caused, and the reliability of a waterproof layer is improved; secondly, the high-polymer self-adhesive waterproof roll is excellent in impact and puncture resistance and capable of bearing the impact of a construction load directly acting on the high-polymer self-adhesive waterproof roll; thirdly, the high-polymer self-adhesive waterproof roll is relatively strong in chemical corrosion resistance and favorable in resistance to alkaline water from concrete; fourthly, the SIS hot melt pressure sensitive self-adhesive is strong in self-healing property.
