[0004] The Chinese invention patent with the application number of 201410842871.8 discloses a preparation method of grafted polypropylene non-woven fabric-based ion exchange material. The photosensitizer is benzophenone, which is grafted to polypropylene non-woven fabric under ultraviolet light irradiation. However, it mainly uses acrylic acid monomers to graft non-woven fabrics without compounding monomers, and it is only used in the field of adsorption of rare earth ions, and its application range is narrow

Embodiment 1

[0025] (1) Preparation of melt-blown polypropylene non-woven fabric: After the polypropylene chips or masterbatches are extruded and heated by a screw extruder to form a molten state, they are then metered into the spinneret by a gear metering pump, and the melt is under the action of its own gravity It is sprayed out by the melt-blown nozzle, and at the same time, it is refined into polypropylene microfibers under the action of high-speed hot air. After being cooled by the outside air, it solidifies into a network, and finally forms a melt-blown polypropylene non-woven fabric, abbreviated as MBPP.

[0026] (2) Boil the melt-blown polypropylene non-woven fabric in deionized water for 90 minutes, soak it in absolute ethanol for 2 hours, and then wash it to remove surface impurities, then dry it at 65-75°C, and weigh it.

[0027] (3) Under the pressure of 30Pa and the power of 40W, the non-woven fabric was first pretreated in a low-temperature plasma device for 5 minutes, so tha...

Abstract

The invention discloses an ultraviolet compound melt-blowing polypropylene oil-absorbing non-woven fabric and its preparation method. According to the preparation method, a photosensitizer, compound monomers, solvents and melt-blowing polypropylene non-woven fabric are involved, wherein the photosensitizer relates to benzophenone, the compound monomers refer to optional two of butyl methacrylate,dodecyl methacrylate, methyl acrylate and butyl acrylate, and the solvents refer to isopropyl alcohol and deionized water. The non-woven fabric can adsorb oil substances in different type, has good oleophylic hydrophobicity, can absorb oil but water, can be reused, can also adsorb some heavy-metallic ion. Besides, as the optimum processing condition good for achieving the optimum oil absorption capacity is reached as researched, the fabric has more thorough oil absorption performance and better oil holding capacity.

Description

technical field [0001] The invention belongs to the technical field of polypropylene nonwoven fabrics, and in particular relates to an ultraviolet composite meltblown polypropylene oil-absorbing nonwoven fabric and a preparation method thereof. Background technique [0002] In recent years, with the increasing frequency of human activities, a series of accidents such as oil field leakage, oil tanker oil leakage, oil pipeline rupture and the discharge of oily wastewater have caused serious pollution of rivers and oceans, bringing immeasurable ecological disasters and economic loss. After crude oil spills, effective and timely recovery and cleaning are necessary measures to protect the environment and human safety, and at the same time reduce the loss of oil resources. Oxidation of oil dissolved in water needs to consume dissolved oxygen in water, causing aquatic organisms to die due to lack of oxygen. In addition, there are a variety of toxic substances in oil and its decom...
