Abstract

The invention discloses a method for preparing functional material by thermosetting resin and application, wherein the thermosetting resin is crushed or broken and then subjected to acid treatment, and can be used for separating oil-water mixture; treating the crushed resin particles with hydrogen peroxide or a mixed solution of hydrogen peroxide and an acid to prepare a binder; bonding the pulverized resin particles with binders such as epoxy resin, polydimethylsiloxane and the like to prepare a hydrophobic coating; amine cured epoxy resin particles useful for acidity indication detection and acid-base gas monitoring; the information encryption material can be prepared by combining an amine-cured and an anhydride-cured epoxy resin. The invention realizes various functional applications of the thermosetting resin by direct crushing or post modification treatment. The method is simple, efficient and low in energy consumption, and can effectively solve the problems of environment and resources caused by wastes.

Description

Method for preparing functional material by using thermosetting resin and application
Technical Field
The invention belongs to the technical field of recovery of high polymer materials, and particularly relates to a method for preparing a functional material by using thermosetting resin and application thereof.
Background
The thermosetting resin and the composite material thereof have excellent performances of high modulus, solvent resistance, heat resistance, light weight, high strength and the like, and are widely applied to the aerospace industry, the automobile industry, the shipbuilding industry, the wind power generation industry, the building industry and the like. However, since the thermosetting resin cannot be dissolved in a solvent or melted by heating, there is a great harm to the environment due to the edges and corners generated during the production process, unused prepreg, and waste material having a long service life. At present, the recovery treatment method of thermosetting resin is mainly burying and burning, but the two recovery methods have serious environmental pollution and can not meet the increasing environmental protection requirement; and the recycling rate is low, which causes serious resource waste. Therefore, efficient recycling of thermosetting resins has become a very important issue from the viewpoint of environment and energy saving.
The current recycling strategies for thermoset resins mainly include physical recycling, energy recycling and chemical recycling. Physical recycling mainly refers to the mechanical method of crushing the thermosetting resin, and using the crushed thermosetting resin as a filler to manufacture various new composite materials, such as artificial boards in buildings, waterproof asphalt or concrete. The recovery method has low cost and relatively simple treatment process. However, the recycled products obtained by recycling have low added value and limited economical efficiency. Energy recovery is a method of recovering thermosetting resin by incineration or the like, and collecting and recovering energy for use. Recovered energyUsually, the fuel is converted into electric energy or heat energy and utilized, and can also be used for heating, steam turbine power generation and the like instead of part of fuel. Although the energy recovery method is simple and easy, the requirements on equipment are high, the conditions are not easy to control, and CO is generated in the incineration process2、SO2Harmful gases such as HCl and HF cause environmental pollution. The chemical recovery is to decompose and recover the thermosetting resin by a chemical or thermal degradation method, and the product obtained by degradation can be used as a production raw material or transportation fuel of downstream industries, and mainly comprises a pyrolysis method, a solvent decomposition method and the like. Pyrolysis method is to destroy the molecular chain of polymer by high temperature to degrade resin matrix, the obtained pyrolysis gas and pyrolysis oil can be used as energy recovery, and solid by-product can be further recycled. Chemical solvents are not used in the recovery process, secondary pollution to the environment is reduced, however, toxic and harmful gases can be released in the treatment process, and the recovery rate of matrix resin is low. The solvent decomposition method mainly uses ethylene glycol, ammonia water, nitric acid and the like as reaction media to carry out resin depolymerization, thereby recycling resin micromolecules in the decomposition liquid. Compared with pyrolysis, the solvent decomposition method is much milder, does not need too high temperature, but generally needs to use organic solvent or catalyst, thereby introducing the problems of solvent recovery and secondary pollution, and has longer reaction time, higher cost and energy consumption, and great difficulty in realizing industrial application.
In conclusion, the existing recycling technology generally has various disadvantages, such as high equipment requirement, complex operation process, harsh reaction conditions, toxic degradation solvent, easy environmental pollution, low recycling efficiency and the like. Therefore, a green and economic recovery mode is sought, and the efficient utilization of the thermosetting resin for preparing the functional material has very important significance.
Disclosure of Invention
Aiming at the problems in the existing thermosetting resin recovery technology, the invention recovers the thermosetting resin by a mechanical crushing method, and is applied to oil-water mixture separation, binding agent, hydrophobic coating, acidity indication detection, acid-base gas monitoring and information encryption, thereby endowing the thermosetting resin with high recovery value.
