Compared with the prior art, the method disclosed by the invention fully uses phenyl butyl sulfonic acid potassium as the fire retardant, after the fire retardant, the antioxidant, the lubricant and the flame-retardant master batches are mixed, extruded and pelleted, the whole preparation technology is simple, a complex ladder temperature control step is not needed, the obtained products have the characteristics of transparence, thin walls, high impact strength, excellent flame retardant property, zero toxicity and zero harm, and the application range is wide.

The invention discloses an ecological plant outer wall which comprises a steel framework and a wall board fixed to one side of the steel framework. The wall board is provided with a bearing part whichextends inwards and is provided with a stud or an internal thread connector in an embedded mode. An inserting fixing part is fixed on the bearing part through the stud or the internal thread connector. Inserting grooves are formed in the two ends of the inserting fixing part. A cultivation plate rack and an outer cover are connected into the inserting grooves correspondingly. An overturning coverplate is rotatably connected to the wall board at one side of the bearing plate, and plant through holes are formed. The steel formwork is fixedly connected with cultivation containers. According tothe technical scheme, plants can gain sunlight well, the physical performance of a curtain wall is not influenced, and the wind resistance, thermal insulation, and watertight and airtight performanceof the curtain wall are not influenced. Mounting, maintaining and plant cultivation are more convenient, and popularization is facilitated.

The invention relates to a preparation method of a single crystal ZnS nano-wire, which belongs to the field of preparative technique of semiconductor material. The method comprises the following steps: inletting the mixed gas of argon and hydrogen with a flow rate of 108 to 113ml/min into a tube furnace; putting the ZnS powder in a quartz boat as a evaporation source, and putting the ZnS powder together with the boat in the tube furnace, and putting a cleaned silicon chip in the furnace, which is 25 to 30mm from the evaporation source, wherein the evaporation source is in the direction of inlet airflow while and the silicon chip is in the direction of outlet airflow; heating the tube furnace to 890 to 910 DEG C with the holding time of 80 to 120min and a pressure of 0.015 to 0.03MPa in the furnace. A layer of white ZnS nano-wire film is deposited on the silicon chip when the temperature of the furnace drops to a room temperature. The method requires a low synthesis temperature and does not apply a foreign catalyst. The prepared ZnS nano-wire has a face-centered cubic structure; the length of 10 to 15Mum and a diameter of only 20 to 30nm at the tip. The nano-wire is single crystal with a higher crystalline quality. The preparation method has the advantages of simple and convenient operating process, available raw material, low cost and easy scale production.

The invention discloses plant oil polyol containing phosphorus and nitrogen as well as a preparation method and application of the plant oil polyol. The preparation method of the plant oil polyol containing phosphorus and nitrogen comprises the following steps: 1) mixing epoxidized soybean oil, 9, 10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide and an acidic/basic catalyst, and carrying out a reaction so as to obtain the plant oil polyol containing phosphorus; and 2) mixing the phosphorus-containing vegetable oil polyol with an amine compound, and reacting to obtain the phosphorus-nitrogen-containing vegetable oil polyol.
