The invention provides room-temperature vulcanized rubber cement for a static balance patch of an aircraft tire and a preparation method of the room-temperature vulcanized rubber cement, and the room-temperature vulcanized rubber cement is prepared by taking natural rubber as a main material and C5 petroleum resin, an anti-aging agent BLE-W, an anti-aging agent RD, an anti-aging agent 4020, an anti-reversion agent HVA-2, precipitated white carbon black, a silane coupling agent, high-wear-resistance carbon black, a diethyl dithiocarbamic acid accelerant and insoluble sulfur as auxiliary materials. One part is mixed through an open mill or an internal mixer to prepare masterbatch containing insoluble sulfur, then the masterbatch is dissolved in n-heptane to obtain first masterbatch cement, the other part is directly dissolved in n-heptane to obtain second masterbatch cement containing the accelerant SDC, and the two kinds of rubber cement are mixed according to the mass ratio of 1: 1 during use. The rubber cement is moderate in hardness and can perfectly accord with a natural rubber inner liner of an existing aircraft tire, the bonding strength between a static balance sheet using the rubber cement and a tire lining of the tire is high, and the rubber cement has the advantages of relatively high tensile strength and tearing strength, good heat aging resistance and room-temperature vulcanization capacity.

This invention discloses a semi-sandwich structured ruthenium triphenylphosphine dithiocarboxylic acid complex with a simple preparation process and its applications. The complex has the structure shown in Figure (I), with the central ruthenium and... η 5 - Coordination with cyclopentadiene, triphenylphosphine, and dithiocarboxylic acid derivatives, wherein the dithiocarboxylic acid ligands are selected from ethyl xanthic acid, isopropyl xanthic acid, ... N,N Diethyldithiocarbamic acid, morpholine dithiocarbamic acid, and carbazole dithiocarbamic acid. This invention employs a simple one-step method of room temperature preparation and recrystallization purification using a ruthenium precursor and dithiocarbamic acid ligand. This method offers advantages such as readily available raw materials, mild reaction conditions, simple post-processing, and high yield. In vitro tests show that the complexes exhibit excellent anti-proliferative activity against non-small cell lung cancer A549 cells, significantly superior to cisplatin. The complexes demonstrate activity by reducing mitochondrial membrane potential, inducing intracellular reactive oxygen species accumulation, and arresting the cell cycle (G1 phase), leading to late apoptosis in A549 cells.

The invention belongs to the field of rubber materials, and particularly relates to a durable high-resilience rubber composite material and a preparation method thereof.

The first accelerant is selected from sulfoxide diethyldithiocarbamate, sulfoxide dibenzyl dithiocarbamate, sulfone dithiocarbamate and sulfone dibenzyl dithiocarbamate, and the second accelerant is selected from sulfoxide diethyldithiocarbamate, sulfoxide dibenzyl dithiocarbamate, sulfone dithiocarbamate and sulfone dibenzyl dithiocarbamate; the second accelerant is 4, 4 '-dithio-dimorpholine, 2-morpholinyl dithio-benzothiazole, N-oxydiethylene-2-benzothiazole sulfenamide, and dibenzoyl morpholine. The invention further discloses a preparation method of the flame-retardant flame-retardant flame-retardant flame-retardant flame-retardant flame-retardant flame-retardant flame-retardant flame-retardant flame-retardant flame-retardant flame-retardant flame-retardant flame-retardant flame retardant. The rubber composite material provided by the invention has excellent high resilience and use durability.

The invention belongs to the technical field of biological medicine and tumor diagnosis and treatment, and particularly relates to manganese diethyldithiocarbamate loaded nanoparticles and a pharmaceutical composition. The nanoparticles loaded with the manganese diethyldithiocarbamate are prepared from an amphiphilic polymer and diethyldithiocarbamate according to the mass ratio of (0.25 to 4) to 1; the manganese diethyldithiocarbamate accounts for more than 50% of the molar mass of the diethyldithiocarbamate; the amphiphilic polymer is one or more of DSPE (Distearoyl Polyethylene)-PEG (Polyethylene Glycol), DSPE-PEG-folic acid, DSPE-PEG-phenylboronic acid and DSPE-PEG-arginyl glycyl aspartic peptide. According to the application, the amphiphilic polymer of the DSPE-PEG and the derivative of the DSPE-PEG and the ethyl dithiocarbamate are adopted to form the nano-particles, and hydrophobic manganese ethyl dithiocarbamate can be wrapped in a hydrophobic micro-area.
