Technical field

The present invention relates to a kind of carbon fibre reinforced composite and red mud recovery and reuse of waste field, specifically a kind of method for comprehensively utilizing carbon fibre reinforced composite and red mud discarded object develops a kind of low energy consumption, large scale CFRP high efficiente callbacks CF new method.Specific method is that carbon fibre reinforced composite is immersed in degraded bleeding agent at normal temperatures and pressures, resin matrix is set to be swelled degraded, isolate carbon fiber or its filler, recycling carbon fibre is made after scrubbed drying, it is added to again using infiltration waste liquid as bonding agent and pore creating material in red mud and clay mixture, sintering prepares building heat preservation or ornament materials, or will infiltration waste liquid and carbon fiber waste-filament mixture be directly added into red mud and clay mixed sintering, prepare fibre reinforced building heat preservation or ornament materials.

Background technology

Red mud is the solid waste discharged in aluminum oxide smelting process, and often producing 1t aluminum oxide can output 1.0-1.8t red mud【Wang Hong etc., based on molten point of Bayer red mud experiment on Comprehensive Utilization of direct-reduction, light metal, 2013,1:19-22；Zhu Jun etc., the synthetical recovery of red mud and utilization, mineral products protection is with utilizing, and 2008,2:52-54】.At present, China's red mud adds up volume of cargo in storage up to 3.5 hundred million t【The red mud from sintering process such as Liu Changjun fundamental characteristics is studied, environmental project journal, 2009,3 (4):739-742；The such as Jiang Yuehua Zhengzhou red mud for alumina plant chemistry and mineral characteristic and recycling are inquired into, light metal, 2007,10:18-21】.Comprehensive utilization ratio is only 5 %.Red mud is largely idle to be stored up, and both land occupation, waste of resource, and cause severe contamination to environment hinder the sustainable development of aluminum i ndustry.Red mud light-weight insulating brick has the advantages that density is low, thermal and insulating performance is good, corrosion-resistant, is incombustible material, can be widely applied to Green energy-saving buildings.With the development of social economy, the energy consumption problem of building receives much concern, and China's building energy consumption is 3 times of developed country, and 10 % that building energy consumption accounted for energy total flow from 1978 rise to 30 more than %.Into after 21st century, new and effective insulating wall material is researched and developed, by the most attention of countries in the world, Europe and the U.S. is particularly.Improve the requirement with building energy conservation to make red mud construction material better meet building function, it is necessary to which constantly research, exploitation are conducive to improving architectural environment, energy-conservation, save useless soil, profit, the production of high-strength, the multi-functional construction material of environmental protection and application technology.

Carbon fibre reinforced composite is classified by matrix, is mainly divided to two major classes:One class is reinforcedathermoset matrices, such as common epoxy resin, unsaturated polyester resin；Another kind of is thermoplastic matrix, such as common nylon, polyethers ether ketone resin.This two classes matrix material has many different properties.Thermoplastic matrix is realized using the change of the thawing of resin, flowing, cooling, the physical state of solidification.The change of its physical state is reversible, i.e., reshaping, processing are possible.In contrast to this, the shaping of reinforcedathermoset matrices is to form cross-linked structure using after the chemical reaction between molecular resin, solidification, and its process is irreversible.With insoluble insoluble characteristic, therefore its recovery is extremely difficult.

With the increasingly extensive application of carbon fibre composite, produced thermosetting resin junk is growing day by day, on the one hand huge pressure is brought to environment, carbon-fibre component containing high value in another aspect composite, if carrying out simply accumulation to composite or burial being handled, it will result in the waste of resource and the pollution of environment, thus the recovery of thermosetting resin and its composite is increasingly subject to the concern of academia and industrial quarters.

Because composite structure is different, resin matrix used also varies, and can solve the problems, such as the recovery of all composites without any method, it is therefore necessary to according to the characteristics of composite itself, develop suitable system scheme, solve the problems, such as the recovery of each class material.Many countries, especially European and American developed countries, have put into effect many related decrees handled on thermosetting resin and its composite, have forbidden handling these solid waste using having environment the method for potential hazard in the world.On the whole, composite recovery technology necessarily develops towards the direction of environmental protection, low energy consumption, low corrosion, and require recovery product can high level recycle, meet the requirement of sustainable development.

Herein from carbon fiber-reinforced resin composite materials and red mud solid waste integrated treatment problem, using treatment of wastes with processes of wastes against one another method, turn waste into wealth, realize that resources circulation is used, reach the purpose of energy-saving and emission-reduction.
