This invention belongs to the field of packaging and printing materials, specifically relating to a high-temperature resistant water-based micro-crosslinked transfer coating. The raw materials for this high-temperature resistant water-based micro-crosslinked transfer coating consist of the following components: methacrylic acid, N-hydroxymethylacrylamide, butyl acrylate, methyl methacrylate, diallyl phthalate, 1,6-hexanediol diacrylate, tricyclodecanedimethylol diacrylate, trimethylolpropane triacrylate, di(trimethylolpropane)tetraacrylate, potassium persulfate, sodium bicarbonate, alkylphenol polyoxyethylene ether ammonium sulfate, nonylphenol polyoxyethylene ether, deionized water, ethanol, ammonia, wetting agent, defoamer, and film-forming agent. Its beneficial effects include a stable reaction process during the preparation of this high-temperature resistant water-based micro-crosslinked transfer coating, reducing the likelihood of slag formation or explosive polymerization; high gloss in the coating film; good adhesion to vacuum metallization; minimal fogging or whitening; high-temperature molding resistance up to 180℃; and easy peeling of PET film with a high yield.

The application discloses a photovoltaic cable for a sea surface wind power system, which comprises copper conductors twisted by a plurality of copper wires, a surface of the copper conductors is coated with an insulating layer, and a sheath layer is coated on the outer surface of the insulating layer; the sheath layer is composed of the following components in parts by weight: ethylene-octene copolymer 50 parts, ethylene-vinyl acetate copolymer 20-40 parts, LLDPE resin 15-30 parts, organic flame retardant 8-20 parts, anti-UV agent 0.3-1 part, irradiation sensitizer 0.5-1.2 parts, lubricant 1-2 parts, antioxidant 0.5-1.5 parts, maleic anhydride 1-3 parts, and oleic acid amide 0.7-2 parts; the irradiation sensitizer is at least one of triallyl isocyanurate, triallyl isocyanurate, and diallyl phthalate. The photovoltaic cable for the sea surface wind power system improves the color stability of the sheath layer of the cable in day-night seasonal changes and improves the weather resistance of the cable according to the harsh use environment of the offshore photovoltaic cable.

This application relates to the field of high-performance adhesive tapes, and more specifically, to a PI silicone gold finger tape and its preparation method. The tape includes a body, from which a polyimide film layer, an organosilicon base layer, and an organosilicon pressure-sensitive adhesive layer are sequentially disposed from the upper surface to the lower surface. The organosilicon pressure-sensitive adhesive layer is prepared by curing the following raw materials in parts by weight: 100 parts organosilicon pressure-sensitive adhesive, 1-3 parts crosslinking agent, 70-100 parts solvent, and 2-8 parts synergist. The synergist is composed of α-Q-trialkoxysilane-terminated polyurethane, diallyl phthalate, and a mixture of isocyanate-containing phenyl organosilicon. The synergist formed by the three compounds in the above scheme synergistically constructs an interpenetrating crosslinking network, thus enabling the tape to exhibit wide-temperature-range adhesive stability, no residue after peeling after treatment at 260℃ for 30 minutes, and excellent long-term aging resistance, meeting the extreme requirements of high-end applications.

This invention discloses an inorganic-doped surface-grafted demulsification functional layer oil-water separation microsphere resin agglomeration material and its preparation method. The invention uses diallyl phthalate-acrylate highly absorbent resin as a substrate, and simultaneously introduces a certain proportion of hydrophilic monomers to form a synergistic effect. Through multi-level structural design, surface phosphonation modification is initiated, and chemically grafted demulsification functional molecular chain matrix and -Si-O-P-inorganic nanoparticles are constructed on the resin surface. This creates a four-in-one micro-nano multi-level rough structure integrating "highly absorbent substrate-phosphine coordination interface-micro-nano rough structure-demulsification functional layer," possessing both demulsification and agglomeration adsorption functions. This invention achieves the coupling of demulsification and agglomeration adsorption functions at the molecular scale, exhibiting highly efficient separation performance for emulsified oily wastewater. It realizes integrated and efficient separation of emulsified oily wastewater through demulsification-agglomeration-adsorption, and possesses excellent cyclic regeneration stability.
