Description
Technical Field
The invention belongs to the technical field of composite material recovery, and particularly relates to a method for recovering a carbon fiber reinforced bismaleimide resin matrix composite material.
Background
Carbon fiber reinforced resin matrix Composite (CFRP) is widely applied in the industrial fields of aerospace, ocean engineering, new energy equipment and the like in view of the characteristics of excellent high strength, thermal stability, fatigue resistance and the like. The increasing amount of CFRP results in the production of large amounts of waste. Generally, CFRP composite materials can be divided into two types, namely thermosetting resin-based composite materials and thermoplastic resin-based composite materials, wherein thermosetting resins have insoluble and infusible properties due to a three-dimensional crosslinked network structure formed by curing, so that the recycling of thermosetting resin-based composite materials for industrial use at present becomes a difficult challenge in the composite material industry field of all countries of the world.
At present, the CFRP composite material waste is mainly recovered by a mechanical method, a pyrolysis method and a chemical method. Among them, the chemical method is the most widely studied technique, and it refers to a technique of breaking the cross-linking bond of the resin matrix by the combined action of the solvent and heat, decomposing the resin matrix into a polymer with low molecular weight or a small molecular substance, dissolving the polymer or the small molecular substance in the solvent, and separating out the carbon fiber. The resin matrix used in CFRP composites is typically a thermosetting epoxy resin (EP), and in order to meet the requirement of higher temperature resistance, many novel thermosetting resin matrix materials, such as Bismaleimide (BMI) resins, have been developed. BMI resins, which have both excellent high temperature resistance and EP easy processability, are considered to be the fastest growing and most promising high performance resin matrix for composite materials. The carbon fiber reinforced bismaleimide resin matrix composite is mainly applied to the field of aerospace, such as various types of aircrafts. There are few reports about chemical recovery methods of carbon fiber reinforced bismaleimide resin matrix composites at home and abroad.
In the prior art, a supercritical/subcritical fluid method is adopted for recycling the carbon fiber reinforced bismaleimide resin matrix composite material, and the degradation efficiency of the method is high, but on one hand, the method is high in required temperature, on the other hand, the method belongs to high-pressure reaction, the high-pressure reaction can only be intermittently operated, and the frequent temperature rise and the temperature drop cause the reaction time to be too long, so that the method is unfavorable for industrialized amplification. In contrast, the resin matrix in the composite material can be degraded into soluble substances under normal pressure by adopting a proper solvent, so that the problem of frequent operation of high-pressure reaction can be avoided, the process is simple and convenient, and the further industrialization is facilitated. Therefore, the method for efficiently and rapidly recycling the carbon fiber reinforced bismaleimide resin matrix composite material under the mild condition with simple operation has good development prospect.

After the reaction is finished, after the reaction device is cooled to room temperature, separating the reacted carbon fiber and the liquid product through a filter screen, collecting the carbon fiber product, washing the collected carbon fiber product with absolute ethyl alcohol for a plurality of times to remove resin matrix residues and adhered degradation liquid on the surface of the carbon fiber product, washing the carbon fiber product with deionized water for 2-3 times, and drying the washed carbon fiber in a baking oven at 100-110 ℃ for 12h. And weighing the dried carbon fiber product, and calculating the degradation rate. The method has the advantages of simple operation, low reaction temperature, short reaction time, high recovery efficiency, good surface morphology of the recovered carbon fiber and good retention rate of mechanical properties.
The technical scheme of the invention is as follows: a method for recycling carbon fiber reinforced bismaleimide resin matrix composite material is characterized by comprising the following specific steps:
step one: cutting the carbon fiber reinforced bismaleimide resin matrix composite material into a sample, and cleaning and drying the cut composite material sample;
step two: adding the composite material sample obtained in the first step into an ethanolamine solvent, heating to 140-160 ℃, and then carrying out constant-temperature reaction for 3-5 h;

step four: and (3) placing the cleaned carbon fiber product in an oven at 100-110 ℃ for drying for 12 hours, and completing the recovery of the carbon fiber reinforced bismaleimide resin matrix composite material.
The invention further adopts the technical scheme that: in the first step, the composite material sample is 30 multiplied by 20 multiplied by 5mm 3 The cutting surface is flat and uniform, and has no tearing phenomenon.
The invention further adopts the technical scheme that: in the second step, the concentration of the ethanolamine solvent is 99.5%.
The invention further adopts the technical scheme that: the ethanolamine solvent is 30mL.
The invention further adopts the technical scheme that: in the third step, a filter screen is adopted to separate the reacted carbon fiber product and the liquid product.
The invention further adopts the technical scheme that: the degradation rate of the carbon fiber reinforced bismaleimide resin matrix composite is calculated, firstly, a composite sample in the first step is weighed, and then, a carbon fiber product dried in the fourth step is weighed; thereafter, the degradation rate was calculated according to the following formula:
wherein: dr is the degradation rate of the composite material, and is wt%; w (W) a G is the mass of the composite material sample; w (W) b G for recycling the carbon fiber mass; w (W) resin 33.5wt% of resin in the composite material.
Advantageous effects
The invention has the beneficial effects that:
the invention provides a method for recycling a commercial carbon fiber reinforced bismaleimide resin matrix composite material under normal pressure. And (3) putting the composite material sample into an ethanolamine solution, reacting for 3-5 hours at 140-160 ℃, separating a degraded carbon fiber product, washing with absolute ethanol and deionized water, and drying in an oven. And weighing the dried carbon fiber product, and calculating the degradation rate. The method has the advantages of simple operation, mild conditions, high recovery efficiency, clean and tidy surface of the recovered carbon fiber and high retention rate of mechanical properties.
Experiments show that the carbon fiber reinforced bismaleimide resin matrix composite material can be efficiently degraded and recovered after being reacted in an ethanolamine solution at 140-160 ℃ for 3-5 hours, the degradation rate reaches 82-98 wt%, and the surface of the recovered carbon fiber is clean and tidy, and the tensile property retention rate is 88-94%.
Compared with the reaction conditions (high pressure, reaction temperature 240 ℃ C., reaction time 10 h) in the prior art, the reaction conditions in the process are milder (normal pressure, reaction temperature 140-160 ℃ C.) and the reaction time is shorter (3-5 h). The conditions of the reaction are greatly reduced due to the different solvents used for the reaction. The three-dimensional network structure of the resin matrix after curing and forming mainly comprises benzene rings and five-membered imide rings, and the benzene rings are relatively stable, so that only the five-membered imide rings can be opened when the resin matrix is decomposed. The five-membered imide ring is acid-resistant, namely stable in acid condition, so that the reaction condition for degrading the bismaleimide resin matrix by using the mixed solvent of calcium nitrate and acetic acid in the literature is harsh, and the treatment time is long; however, the catalyst is unstable under alkaline conditions and tends to open the ring. Therefore, the alkaline organic solvent ethanolamine is used as a reaction medium, so that the bismaleimide resin matrix in the composite material is efficiently decomposed under mild conditions, and the degradation and recovery of the composite material are realized.
The recycled carbon fiber has small loss of mechanical property, the whole operation process is simple, convenient and safe, the used reagents are common reagents, are cheap and easy to manage, and are used for promoting the industrialized recycling of the carbon fiber reinforced thermosetting resin matrix composite material and adding tiles. The invention is described in detail below with reference to the drawings and the detailed description.
