2 results about "Styrene Monomer" patented technology

Styrene is one of the most important monomers produced by the chemical industry today. Styrene monomer is a basic building block of the plastics industry. The conventional method of producing styrene involves the alkylation of benzene with ethylene to produce ethylbenzene, followed by dehydrogenation of ethylbenzene to styrene.

Plasma preparation method of polystyrene fluorescent microspheres and reaction equipment of plasma preparation method

ActiveCN105713126ALong fluorescence lifetimeImprove thermal stabilityLuminescent compositionsOrganic synthesisPolystyrene
The invention discloses a plasma preparation method of polystyrene fluorescent microspheres and reaction equipment of the plasma preparation method, and relates to the technical field of organic synthesis of fluorescent microspheres. A rare earth organic complex is adopted as a starting raw material, plasma of polystyrene is polymerized on the surface of the rare earth organic complex to coat the surface of the rare earth organic complex with a layer of polystyrene, and thus polystyrene fluorescent microspheres are formed. The method includes the main steps of 1, performing plasma pretreatment of the rare earth organic complex; 2, performing plasma polymerization, wherein plasma of polystyrene monomers is polymerized and deposited on the surface of the rare earth organic complex. The polystyrene fluorescent microspheres obtained through the preparation method have a long fluorescent lifetime and good heat stability, and the preparation process is simple, easy to perform and free of environmental pollution.

Automobile trim material combined with non-woven fabric and woven fabric

InactiveCN105034535ASignificant advantage effectLow priceSynthetic resin layered productsLaminationSodium bicarbonateWarm water
The invention provides an automobile trim material combined with a non-woven fabric and a woven fabric The automobile trim material is prepared by virtue of the following steps: 1, cutting ramie into 70mm fibers, putting the fibers into a stainless steel vessel, adding a sodium bicarbonate solution and stirring for 60 minutes; 2, cleaning jute fibers and drying the jute fibers; 3, adding warm water at a temperature of 30 DEG C, performing constant-temperature bath for 60 minutes, adding 1% constant temperature bath and 0.1% ceric ammonium nitrate, cleaning, and then drying; 4, putting the jute fibers on fur machine equipment, and performing shredding mixing on the jute fibers and polypropylene fibers; 5, carding the fibers into a net shape by use of a carding machine; 6, paving the fibers to form a multilayer net body with weight per square meter of 1500g; 7, paving polypropylene fabrics on both sides as surface layers, and performing reciprocating reinforcement by use of a needling machine; and 8, pressing to prepare an automobile trim material sectional material by use of die pressing equipment. The automobile trim material produced by the method is low in price, is capable of adsorbing sound and insulating heat, is high in rigidity, durable in use, simple in technological process and free from environmental pollution.
