Abstract
The invention discloses an environment-friendly dirty object manual collecting bag. The environment-friendly dirty object manual collecting bag is formed by processing a poly vinyl alcohol thin film, and the thin film comprises the following materials (in percentage by weight): 10-90% of poly vinyl alcohol resin raw material, 0-20% of a filler, 0-50% of natural polymer material and 8-50% of plasticizer. The environmental-friendly dirty object manual collecting bag has water resistance and toilet flushing property at the same time, is used for collecting dirty objects containing certain water such as faeces and vomit of patients and faeces of pets, is difficult to break, can be also thrown into a toilet to be rushed and melted and is convenient to use, environment-friendly and healthful.
Description
Technical field
The present invention relates to a kind of biodegradation type collecting bag, especially provide the filthy object of a kind of environment-friendly type manual collecting bag.
Background technology
21 century is environmental protection century, and environmental problem is increasingly important, and energy resource more is becoming tight, and constructs recycling economy society, walks the criterion that sustainable development path has become all trades and professions development and mankind's activity.For adapting to the requirement of New Times, Plastic Packaging Materials is except requiring to satisfy the requirement that Package Quality and quantity etc. is improved market day by day, and its development must be to economize on resources save energy, easy to be recycled with the back, easily dispose or easily dissolved by environment or be degraded to the starting point of technological development.Plastic wrapping novel material, novel process, new technology, product innovation continue to bring out, and forward high-performance, multi-functional, active adoption new raw material, new technology, widen Application Areas and directions such as plastic wrapping and environmental protection coordinated development develop.
Usually return in the daily life and run into reluctant filthy article such as patient's rubbish, pet excrement; contain many germs in these dunghills; as: germs such as tubercule bacillus, brucellosis, salmonellosis; if let alone to be exposed to occurring in nature; not only hinder environmental health, and germ propagates or enters underground water, river and the polluted water resource easily in the ight soil in air.Properly in time handling these dunghills, is current environmental protection requirement.
Behind the collecting dung that pet owner can only accomplish pet is drained it is abandoned as domestic refuse at present.Owing to contain a certain amount of moisture in the ight soil, for ease of collecting and carrying, more commonly use the collecting bag of common plastic film processing such as polyethylene (P0lyethene is called for short PE) film, be characterized in being difficult for infiltration in the process of carrying and certain intensity and low price being arranged.But general thins such as PE film all are the nondegradable macromolecular materials of occurring in nature, and a large amount of uses will bring following environmental problem.
How can conveniently use, to collect at any time, can not pollute environment again, be a urgent problem.
Summary of the invention
Technical problem to be solved by this invention is: provide the filthy object of a kind of environment-friendly type manual collecting bag.
The technical solution used in the present invention is:
The manual collecting bag of the filthy object of a kind of environment-friendly type, be to utilize PVA (PVOH) FILM to process, described film is made up of following material: polyvinyl alcohol resin raw material 10-90wt.%, filler 0-20wt.%, natural macromolecular material 0-50wt.%, softening agent 8-50wt.%.
Preferably, described polyvinyl alcohol resin raw material is that the polyvinyl alcohol with low alcoholysis level resin of 80-93m0l% and high alcoholysis degree polyvinyl alcohol resin that alcoholysis degree is 93.1-99.99m0l% are formed by alcoholysis degree, and the part by weight of described polyvinyl alcohol with low alcoholysis level resin and high alcoholysis degree polyvinyl alcohol resin is 90: 10-0: 100.
Preferably, the polymerization degree of described polyvinyl alcohol resin is 2000-2200.
Preferably, described filler is a kind of in paraffin, polyethylene wax, silicon-dioxide, talcum powder or the calcium carbonate.
Preferably, described natural macromolecular material is a kind of in Mierocrystalline cellulose, xylogen, starch, chitin and the chitosan.
Preferably, described softening agent is a kind of in glycerine, Glycerol dimer, polyoxyethylene glycol, polypropylene glycol, the Sorbitol Powder.
The filthy manual collecting bag of environmental protection of the present invention has water tolerance and flushing the toilet property simultaneously, is used for collecting the dunghill that contains certain moisture, for example when the ight soil of sufferer, vomitus or pet dung etc., namely be not easy brokenly suitablely, can lose again to dash in the toilet and melt, easy to use, environmentally-friendly sanitary.
Embodiment
Specifically describe below by the present invention of embodiment.
The preparation method of toilet-flushing type biodegradation type collecting bag provided by the present invention can may further comprise the steps:

Step 2: the compound of step 1 preparation added to carry out granulation in single screw rod or the twin screw extruder, the temperature range from the feed opening to the discharge port is controlled to be 95-150 ℃, 150-250 ℃, 150-250 ℃, 150-250 ℃, 150-200 ℃ successively;
Step 3: the pellet of the compound of step 1 preparation or step 2 preparation added to carry out blown film in single screw rod or the twin screw extruder in 150-250 ℃ temperature range, the temperature range from feed opening to the discharging mode draught animals is controlled to be 90-150 ℃, 150-250 ℃, 150-250 ℃, 150-250 ℃, 150-250 ℃ successively;
Step 4: the processing film of using step 3 extrusion-blown modling to obtain becomes single bags or is combined processing and manufacturing with the water-soluble film of routine to become double-ply bag.
S embodiment 1:
Thick 30 microns of PVA film, water-soluble partially (flushing the toilet property) material: PVA resin 74%, calcium carbonate 0.7%, talcum powder 11%, glycerine 11%, water 3.3% (weight percent).
Embodiment 2:
Thick 30 microns of PVA film, water-soluble material partially: PVA resin 18%, starch 42%, calcium carbonate 1%, glycerine 21%, Sorbitol Powder 12%, water 6% (weight percent).
