Description
Technical field
The invention belongs to discarded printing material resource utilization and cycling and reutilization technical fields, are related to a kind of useless paper money of utilization
The method that ticket paper, concerning security matters waste paper and waste plastics prepare composite material.
Background technique
Useless banknote is a kind of special waste paper resources, and banknote body paper mainly uses cotton fiber, has fiber fineness high, fine
The features such as dimension is long, draw ratio is big, flexible, intensity is good.With the fast development of China's economic growth, banknote is in financial field
Circulation is increasing, due to factors such as time, environment, frequency of use and keeping methods, inevitably results in the broken of banknote
Replacement is undermined, is required according to the People's Bank's " damaged RMB recovery operation checks embodiment ", it must not be to customer payment " seventy percent
Newly " RMB below, this increases the yield of useless paper money every year further.
Due to the particularity of banknote in use, the characteristics such as its is durable, physical index is excellent are determined, meanwhile,
Using a variety of special mode of printings, ink content is more and complicated component, can not effectively be removed using current de-inking method
Ink, and the printing ink wastewater processing difficulty removed is big, so that useless paper money has greatly in terms of recycling with resource utilization
Difficulty.And it uses and burns and fill out the significant wastage that the useless paper money of the measures such as sea processing undoubtedly causes quality plant fiber.In addition, in useless paper money
Also need to fully consider the concerning security matters problem of these special waste paper during ticket/concerning security matters waste paper resource utilization.So useless paper money
Ticket/concerning security matters waste paper application technology as the second resource becomes current line a great problem in the industry.In addition to this, handling process is transported in banknote
In, a large amount of waste plastic packing cases are also generated, how this high-quality waste plastics of high-efficiency resource recycling is paid close attention in the industry.
The present invention uses useless banknote/concerning security matters waste paper and packaging waste plastics for raw material, using hot pressing/extrusion molding process technology
The compound composite material of production green, has tempting application prospect, useless paper money efficient utilization, resource-effective and protection, discard
Object recycles and resource utilization, the exploitation of green construction material and energy-saving and emission-reduction etc. all have it is extremely important existing
Sincere justice.
Summary of the invention
The object of the present invention is to provide a kind of sides that composite material is prepared using useless bank-note paper, concerning security matters waste paper and waste plastics
Method, solving the prior art, presence can not effectively remove ink, place in terms of processing to useless bank-note paper, concerning security matters waste paper and waste plastics
The problem of reason difficulty is big and is unable to resource recycling.
The technical scheme adopted by the invention is that preparing composite material using useless bank-note paper and concerning security matters waste paper waste plastics
Method, specific operation process include the following steps:
