Problems solved by technology

The above three requirements have created difficulties for the preparation of polymer solutions for electrospinning. The existing intrinsic oil-absorbing polymers all have cross-linked structures, which reflect the insoluble characteristics, and it is difficult to prepare solutions. Even if linear polymers are obtained, although they can be prepared A satisfactory solution is obtained, but the fiber mat is easily soluble in oily organic matter after forming and does not have oil absorption function

Abstract

The invention discloses a manufacturing method of oil absorbing fiber felt, belonging to the technical field of manufacturing of fiber felts. By simultaneously adopting a semi-interpenetrating polymer network technique and an electrostatic spinning technique, the manufacturing method comprises the following steps: firstly, synthesizing monomers, which are unlikely to form cross-linked structures, to linear non-crosslinking methacrylate polymers by suspension polymerization; dissolving the polymers in a solvent suitable for electrostatic spinning to prepare liquor, and adding monomers, which are likely to form cross-linked structures and contain an initiator, into the liquor; preparing polymer liquor containing the semi-interpenetrating network structure by liquor polymerization; after insulating and defoaming, spraying the liquor to a receiving roller by an electrostatic spinning method; and along with volatilization of the solvent, after fibers are cured, fixing the semi-interpenetrating network structure inside the fibers so as to form the fiber felt with an intrinsic oil absorbing function. Compared with existing polypropylene fiber felt, the fiber felt disclosed by the invention has the advantages of higher adsorption rate, stronger oil keeping capacity and the like, and satisfies the industrial practical demands.

Description

technical field [0001] The invention relates to a fiber mat manufacturing technology, in particular to a method for manufacturing a polymethacrylate fiber mat with an oil-absorbing function. The manufacturing method utilizes semi-interpenetrating polymer network technology and electrospinning technology at the same time. Background technique [0002] According to the data released by the Ministry of Environmental Protection in 2011, there are more than 30,000 industrial organic wastewater polluting enterprises with oily organic substances under key monitoring nationwide. The ecological environment has brought devastating damage. It can be seen that the disorderly discharge of industrial organic wastewater and various frequent oil spill accidents have become the main channels for oily organic matter to pollute water resources and the ecological environment. Oily organic pollution has the characteristics of environmental persistence, bioaccumulation, semi-volatility, long-dist...
