Toilet-flushing type biodegradable collection bag

Abstract

The invention provides a biodegradable collection bag, in particular provides a flushing-type biodegradable collection bag which has certain water resistance and can be rapidly softened or smashed by a larger current rush. The flushing-type biodegradable collection bag is made from a film which is made from processing materials comprising polyvinyl alcohol resin, a packing material, a natural polymer material, a plasticizer and the like. The flushing-type biodegradable collection bag organically combines the water resistance and the flushability of the film, and meets the flushability and biological degradability while having certain water resistance. The biodegradable collection bag can not be dissolved and broken while being used for collecting dunghill with certain moisture such as feces of patients, puke and feces of pets, and can be rapidly softened and smashed to be flushed into a sewage pipe after being put into a toilet to contact with a large amount of water, and finally the biodegradable collection bag can be completely biodegraded in a septic tank.

Description

technical field [0001] The invention relates to a biodegradable collection bag, in particular to provide a flushing type biodegradable collection bag which has certain water resistance but can be softened or broken rapidly by the impact of relatively large water flow. Background technique [0002] In the current society, the pet feces caused by the increasing number of pets have brought many environmental problems. Pet feces contain many germs, such as: tuberculosis, brucellosis, salmonellosis and other germs. If they are allowed to be exposed to nature In addition, it is not only harmful to environmental sanitation, but also the germs in the feces are easy to spread in the air or enter groundwater and rivers to pollute water resources. It can be said that these pet feces have become a serious source of pollution. Therefore, many countries have expressly stipulated that pet owners must collect and process the feces of their pets. [0003] At present, pet owners can only co...

AI Technical Summary

Problems solved by technology

However, ordinary films such as PE films are non-degradable polymer materials in nature, and a large amount of use will bring the following environmental problems: 1) Since the bag film does not have biodegradability and flushability, people can only use it after use. It is discarded as household garbage, resulting in a large amount of non-degradable garbage; 2) discarding and processing pet feces containing many germs as daily garbage will easily cause germs to spread in the air, which will bring harm to the health of residents and garbage disposal personnel. Harm; 3) It is very difficult and costly to classify and recycle garbage; 4) When landfilling is used to dispose of garbage, pet feces containing many germs are likely to cause germs to enter the groundwater during landfilling or in rivers, thereby polluting water resources

Moreover, what the patent pursues is still the water solubility of the film

[0008] Therefore, the various PVA films currently disclosed are difficult to fully meet the needs of people to collect and process some filth with a certain amount of water in their daily lives, and can be discarded in ordinary flush toilets for treatment, especially for collecting pet feces. The need for such filth
