2533 results about "Epoxidized soybean oil" patented technology

Epoxidized soybean oil (ESBO) is a collection of organic compounds obtained from the epoxidation of soybean oil. It is used as a plasticizer and stabilizer in polyvinyl chloride (PVC) plastics. ESBO is a yellowish viscous liquid.

Cold-resistant oilproof flame-retardant PVC (Polyvinyl Chloride) cable material and preparation method thereof

The invention relates to a cable material, and in particular relates to a cold-resistant oilproof flame-retardant PVC (Polyvinyl Chloride) cable material and a preparation method thereof. The polyvinyl chloride cable material comprises the following components: PVC resin powder, a plasticizer, nitrile butadiene rubber powder, a stabilizer, epoxidized soybean oil, a fire retardant, Elvaloy, an antioxidant and a lubricant. The preparation method comprises the following steps of: evenly stirring the PVC resin powder, the plasticizer, the nitrile butadiene rubber powder, the stabilizer, the epoxidized soybean oil, the fire retardant, the Elvaloy, the antioxidant and the lubricant in a high-speed mixer; performing banburying in a banbury mixer at the temperature between 120 and 140 DEG C; extruding by using double screw rods; granulating by grinding and hot-cutting; conveying materials by using a cyclone separator; and screening by using a vibrating screen and packaging, thereby obtaining the finished cold-resistant oilproof flame-retardant PVC cable material product. Compared with the common flame-retardant PVC cable material, the polyolefin cable material provided by the invention has the effects that the cold-resistant performance is improved; the oilproof performance of the product is improved greatly; and the problem that the cold-resistant PVC cable material plasticizer is easy to separate out is solved.

Method for preparing epoxidized soybean oil or epoxy fatty acid methyl (ethyl) ester through catalysis of organic rhenium oxide-urea peroxide

The invention discloses a method for preparing epoxidized soybean oil or epoxy fatty acid methyl (ethyl) ester through the catalysis of organic rhenium oxide-urea peroxide, which belongs to the technical field of liquid-phase catalytic epoxidation. The method utilizes a biomass material, namely soybean oil or unsaturated fatty acid methyl (ethyl) ester, adopts organic rhenium oxide as a catalyst, utilizes urea peroxide to react to synthesize the epoxidized soybean oil or the epoxy fatty acid methyl (ethyl) ester under the conditions without carboxylic acid and protonic acid, and avoids the use of strong acid catalysts during the epoxidation, so the method has small corrosion on equipment; the method avoids the use of the carboxylic acid, makes the post-treatment simple, and has no wastewater; and the method ensures that the process has simple operation, meets the requirement of epoxidized clean production, and is environment-friendly. The product can be taken as a plasticizer to be widely applied to nontoxic polyvinyl chloride (PVC) products and transparent PVC products, namely industrialized products such as transparent bottles, transparent boxes, food and drug packing materials, medical PVC 'blood transfusion bags', environment-friendly photocurable coatings and the like.
