The application provides a polypropylene dissolving agent and application thereof, and belongs to the technical field of olefin dissolving agents.The polypropylene dissolving agent comprises the following raw materials in mass fractions: dicyanamide salt ionic liquid 10-25 parts, betaine salt 5-15 parts, tetrafluoroborate salt ionic liquid 5-15 parts, ethyl sulfate salt ionic liquid 5-15 parts, acetate salt ionic liquid 10-20 parts, long carbon chain anion ionic liquid 10-40 parts, dispersant 2-18 parts and auxiliary agent 2-20 parts.Under the condition of 180-280 DEG C, the mass fraction of the polypropylene dissolving agent of the application to polypropylene with a molecular weight of 500-1000 million can reach more than 15%, and the wet processing of the ultra-high molecular weight polypropylene into a film can be realized, and the polypropylene diaphragm or polypropylene fiber obtained by processing has the characteristics of high temperature resistance, high strength (including tensile and puncture strength), high porosity, high air permeability and the like.

This invention discloses a zinc-containing hydraulic oil composition, which, by weight percentage, comprises the following components: 0.4-0.8 wt% zinc dialkyl dithiophosphate, 0.2-0.5 wt% bisphenol antioxidant, 0.1-0.25 wt% auxiliary antioxidant, 0.2-0.5 wt% ionic liquid, 0.02-0.05 wt% rust inhibitor, 0.01-0.02 wt% demulsifier, 0.01-0.02 wt% antifoaming agent, 1-5 wt% ester base oil, and the balance being mineral base oil. The zinc-containing hydraulic oil composition disclosed in this invention employs a three-antioxidant system, an azo ethyl sulfate ionic liquid, and a polyester compound system, providing effective corrosion and anti-wear protection for metals. It possesses advantages such as antioxidant properties, low sludge content, and good compatibility with other additives. Through the mutual compatibility of various additives, it exhibits excellent anti-wear properties, rust prevention, demulsification properties, thermal stability, and hydrolytic stability, meeting the stringent operating requirements of high-temperature and high-pressure hydraulic oil systems.
