There are provided a resin composition, which has optical properties such as a high refractive index, has excellent restorability and scratch resistance, and has good adhesion to a substrate, and, when utilized as an optical member (lens) used, for example, in screens for projection televisions or the like, can satisfy various property requirements, and a cured product of the resin composition. The resin composition comprises: an oligomer component comprising urethane (meth)acrylate, produced by reacting a bisphenol A polyalkoxydiol, an organic diisocyanate and a hydroxyl-containing mono(meth)acrylate, and a bisphenol A epoxy (meth) acrylate; a monomer component comprising a phenoxy polyethylene glycol (meth)acrylate and a bisphenol A polyethoxydiol di(meth)acrylate; and a photopolymerization initiator. The resin composition has a refractive index of not less than 1.55 after resin curing.

The invention discloses a novel oxygen fertilizer and preparation and application methods of the oxygen fertilizer. Mixtures of one or more of calcium peroxide, sodium peroxide and magnesium peroxide act as a core; nano chitosan doped with sodium alginate as the binding agent serves as a wrapping membrane; and the outer layer of the wrapping membrane is further wrapped by paraffin as a conditioner, so that a slow-release oxygen fertilizer is prepared. The oxygen fertilizer contains 70-75% of the core by weight, 20-25% of the wrapping membrane by weight, and 3-10% of the conditioner by weight and the particle diameter of the oxygen fertilizer particles is 3-10mm. The novel oxygen fertilizer prepared by the preparation method disclosed by the invention can supply oxygen to waterlogged plants for a long time and is convenient and simple to apply, simple in production process and environment-friendly, and saves time and labor and can be used widely.

The invention discloses a core-shell type silicon-containing synergistic flame retardant and a preparation method thereof, which is characterized in that 50ml of deionized water and 150ml of ethanol are added into a reaction kettle equipped with a stirring and reflux device, and after stirring evenly, 50g of Ammonium polyphosphate and 1g OP-10, heated to 45°C under stirring, added concentrated ammonia water to adjust the pH value to 9-11, then slowly added 5g organic silicon oxide compound dropwise at a speed of 3ml / min, stirred for 150min, and then The reaction kettle was lowered to room temperature, filtered, washed, and the filter cake was dried at 120°C and 30mmHg. The average particle size of the obtained product does not increase significantly, the free flow of particles is good, the shell is dense and uniform, the water property is greatly reduced, and the high temperature water resistance is significantly improved. It can be used as a polymer material such as polyolefin, polyurethane, rubber, and foam. Flame retardant, it can also be used for flame retardant of paper, wood, fabric, etc.

The invention relates to an on-line replaceable thermocouple used for measuring the temperature of a sulfur furnace, including a thermocouple and a protective sleeve outside the thermocouple, and the thermocouple with the protective sleeve measures temperature through the thermocouple installed on the sulfur furnace. The support pipe extends into the sulfur furnace, and the side of the temperature-measuring support pipe is provided with a first blowing interface and a second blowing interface which are spaced apart from each other. One end of the first and second blowing interfaces communicates with the temperature-measuring support pipe. The other end of the first and second blowing ports is connected to the protective gas source, the rear end of the thermocouple is connected to the junction box, the junction box is sealed with the temperature measurement support tube, and the temperature measurement support tube between the protective sleeve and the junction box A micro-pressure pressure gauge is installed on the top, and the rear end of the temperature-measuring support tube is provided with a rotary valve capable of closing the temperature-measuring support tube. The invention can effectively avoid the leakage and leakage of hydrogen sulfide gas, prolong the service life of thermocouples, improve the accuracy of temperature measurement, and replace the thermocouples without shutting down the furnace, thereby prolonging the operating period of the device and greatly improving the production efficiency.
