Method for producing environment-friendly rubber softening oil

The invention relates to a method for producing environment-friendly rubber softening oil. The method is characterized by comprising the following steps: decompressing and distilling mineral oil; adding a catalyst into cut fraction at a temperature of between 280 and 340 DEG C to carry out a high-pressure hydrogenation reaction; adding the obtained product into carclazyte to be refined, and carrying out vacuum filtration to obtain refined mineral oil; treating bottom oil of a vacuum tower by the conventional propane deasphalting process to obtain an asphalt solution; distilling the asphalt solution under reduced pressure, taking cut fraction at a temperature of between 270 and 330 DEG C to be oxidized to obtain oxidized asphalt; mixing and stirring the obtained refined mineral oil and the oxidized asphalt in proportion by weight of 2.5-3.5:1.2-1.5 at a temperature of between 50 and 80 DEG C. The environment-friendly rubber softening oil has the advantages that the softening property, the compatibility and the intermiscibility are the same as or similar to the prior product high aromatic oil, but as the rubber softening oil does not contain or contains trace polycyclic aromatic hydrocarbon, so the rubber softening oil does not have carcinogenicity, does not pollute human body and environment, and meet the requirement of environment-friendly rubber extending oil.

Polyphenol cross-linking agent and application thereof to preparation of anti-calcification biovalve

The invention relates to a polyphenol cross-linking agent and application thereof to preparation of an anti-calcification biovalve. The polyphenol cross-linking agent is prepared in a way that polyphenol compound is dissolved in organic solvent, and then, buffer solution is adopted for dilution, wherein the polyphenol compound is selected from one or multiple of procyanidine, curcumin, resveratrol, puerarin, aloin and aloe-emodin. The preparation method for the anti-calcification biovalve comprises the following steps: dipping a bio-based material which completely removes cells into the polyphenol cross-linking agent to be subjected to cross-linking, and fully cleaning after ending; dipping in PBS (polybutylene succinate) solution and / or D-Hanks solution to be subjected to post-processingto obtain the anti-calcification biovalve. The anti-calcification biovalve provided by the invention has better mechanical property and stability, tissue calcification, inflammation and thrombus can be obviously reduced, biotoxicity is lowered, service life is greatly prolonged, and the defects of serious calcification, short service life and the like of biological cardiac valve materials processed with a traditional glutaraldehyde crosslinking method are overcome.

Copper ferrite/graphene quantum dot composite material, and preparation method and application thereof

The invention provides a copper ferrite/graphene quantum dot composite material, and a preparation method and application thereof. The material is well applicable to colourimetry detection field, and is especially applicable to colourimetry detection on organic phosphorus pesticides. Graphene quantum dot and copper ferrite are firstly respectively prepared and then mixed, so that a CuFe2O4/GQDs composite material is prepared by utilizing electrostatic incorporation effect. Additionally, the composite material possesses excellent electrical conductivity, good electron transmission performance, substantially-enhanced catalytic effect, and further enhanced detection sensitivity. Also, because the GQDs surface carries a certain amount of hydrophilic groups, combination of GQDs is relatively beneficial for dispersing of CuFe2O4/GQDs in water. The method detecting organic phosphorus pesticides employs a chromogenic substrate TMB which is relatively sensitive in color development and free of carcinogenicity, the employed CuFe2O4/GQDs nanometer composite material possesses magnetism, and is extremely easily separated, recovered and utilized through a physical process, and the green chemistry idea is satisfied.
