Abstract
The invention belongs to the field of environmental protection technology, discloses a method used for biological treatment of medical abandoned infusion bags, and provides a degradable mulch film prepared from the medical abandoned infusion bags. The method is capable of realizing recovery of the medical abandoned infusion bags, obtaining the degradable mulch film with excellent properties, changing waste into valuables, and achieving two aims via one action.
Description
Technical field
The invention belongs to environmental technology field, be specifically related to a kind of method of the discarded infusion bag of medical treatment of carrying out a biological disposal upon, also relate to a kind of environment-friendly degradable mulch film that utilizes discarded infusion bag to prepare.
Background technology
Along with plastics consumption constantly increases, waste plastic is also on the increase.China's waste plastic is mainly plastics film, plastic wire and fabric, porous plastics, plastic package box and container, daily plastic goods, plastics bag and agricultural mulching etc. at present.Wherein medical transfusion bag belongs to the one of medical waste plastic, and because it contains drug contamination, very large restriction has been received in its recovery.At present, medical infusion bags is mainly the soft bag of non-PVC composite membrane, non-PVC composite membrane be plastic material by three layers of different melting points as polypropylene (PP), polyethylene (PE), polyamide (PA) and multiple resilient material (SEBS), co-extruded films under 100 grades of cleaning conditions.PP material has good aqueous vapor barrier property, has good consistency with various liquids, can guarantee the stability of liquid; But it reclaims the general mode of burning that adopts, and environment has been produced to pollution, and wasted resource.
Degradative plastic film is a kind of Novel mulching film producing for the needs of environment protection for adapting to society, and main raw material is that degradation master batch mixes and produces with plastic pellet masterbatch.Degraded is to utilize the microorganism of occurring in nature to corrode mulch film or utilize the effect of sunlight oxidation and the degraded that reaches.Along with human society is to the deepening constantly of the environmental problem level of understanding, solve " white pollution " that discarded mulch film causes and set up environment friendly society, set up the good interaction of human and environment, only way is applied degradable mulch exactly.And wherein the development of photo-degradable and bio-degradable mulch film and promote particularly important.The research of two degradative plastic films, is the development trend of China's mulch film industry from now on, is also the prerequisite of Sustainable Development agricultural.There is more degradable mulch in prior art, but a lot of mulch film is when having improved degradation function, has reduced the physico-chemical property of mulch film itself, and such as the parameter such as tensile strength and elongation at break obviously declines; In this case, staff can not select degradable mulch, causes environment-friendly degradable mulch film large-scale promotion to apply.
Prior art needs a kind of method of the discarded infusion bag of medical treatment of carrying out a biological disposal upon, and the degradable mulch that utilizes discarded infusion bag to prepare.
Summary of the invention
In order to overcome the defect of prior art, the invention provides a kind of method of the discarded infusion bag of medical treatment of carrying out a biological disposal upon, and the degradable mulch that utilizes discarded infusion bag to prepare is provided; The present invention had both recycled discarded infusion bag, had also prepared preferably degradable mulch of various aspects of performance.
The present invention realizes in the following way,
A method for the discarded infusion bag of medical treatment of carrying out a biological disposal upon, it comprises the steps:
1) collect the discarded infusion bag of medical treatment, put into 0.9% sodium chloride solution and soak 240 hours, then take out and dry, put in plastic crusher, be ground into particle, obtain raw material A;
2) raw material A, polyglycolic acid, poly(lactic acid), chitosan, Polyvinylpyrolidone (PVP), methylcellulose gum, ground dolomite, lime borate and the W-Gum that step 1) are obtained are put in retort successively, the stirring of raw material limit is added on limit, within standing 30 minutes after stirring, obtains mixture 1; Wherein the part by weight of raw material A, polyglycolic acid, poly(lactic acid), chitosan, Polyvinylpyrolidone (PVP), methylcellulose gum, ground dolomite, lime borate and W-Gum is: 100:6:15:20:8:12:2:3:30;
3) again by step 2) gained mixture 1 adds twin screw extruder, at screw speed 120-180 rev/min, at 180 ℃-200 ℃ of temperature, melt extrudes granulation, obtains mixture 2;
4) step 3) gained mixture 2 is mixed and obtains mixture 3 with dioctyl sebacate, agar, Trisodium trimetaphosphate, iron stearate, cobalt stearate, epoxy chloropropane and barium stearate under the condition of 200 revs/min; Wherein, the part by weight of mixture 2, dioctyl sebacate, agar, Trisodium trimetaphosphate, iron stearate, cobalt stearate, epoxy chloropropane and barium stearate is: 100:1:0.3:0.1:0.2:0.1:0.1:0.3;
5) again step 4) gained mixture 3 is sent into single screw extrusion machine, hot-melt extruded blowing at 180 ℃, cuts, packs and get final product.
The invention also discloses a kind of degradable mulch, it is prepared as follows and forms:
1) collect the discarded infusion bag of medical treatment, put into 0.9%(mass volume ratio) sodium chloride solution soak 240 hours, then take out and dry, put in plastic crusher, be ground into particle, obtain raw material A;
2) raw material A, polyglycolic acid, poly(lactic acid), chitosan, Polyvinylpyrolidone (PVP), methylcellulose gum, ground dolomite, lime borate and the W-Gum that step 1) are obtained are put in retort successively, the stirring of raw material limit is added on limit, within standing 30 minutes after stirring, obtains mixture 1; Wherein the part by weight of raw material A, polyglycolic acid, poly(lactic acid), chitosan, Polyvinylpyrolidone (PVP), methylcellulose gum, ground dolomite, lime borate and W-Gum is: 100:6:15:20:8:12:2:3:30;
3) again by step 2) gained mixture 1 adds twin screw extruder, at screw speed 120-180 rev/min, at 180 ℃-200 ℃ of temperature, melt extrudes granulation, obtains mixture 2;
4) step 3) gained mixture 2 is mixed and obtains mixture 3 with dioctyl sebacate, agar, Trisodium trimetaphosphate, iron stearate, cobalt stearate, epoxy chloropropane and barium stearate under the condition of 200 revs/min; Wherein, the part by weight of mixture 2, dioctyl sebacate, agar, Trisodium trimetaphosphate, iron stearate, cobalt stearate, epoxy chloropropane and barium stearate is: 100:1:0.3:0.1:0.2:0.1:0.1:0.3;
5) again step 4) gained mixture 3 is sent into single screw extrusion machine, hot-melt extruded blowing at 180 ℃, cuts, packs and get final product.
The discarded infusion bag of medical treatment that the application reclaims use generally refers to the soft bag of the conventional non-PVC composite membrane of prior art.
The beneficial effect that the present invention obtains is as follows: the present invention had both recycled discarded infusion bag, also utilizes this waste to prepare preferably degradable mulch of various aspects of performance for raw material, kills two birds with one stone; The present invention has reduced environmental pollution, and waste is effectively utilized, and has realized and having turned waste into wealth; Mulch film prepared by the present invention not only possesses good degradability, and the parameter such as tensile strength and elongation at break has also had raising; The mulch film production method simple possible that the present invention produces, raw materials cost is cheap, can be mass-produced.
