The development of the last 70 th century has been developed for over 50 years, and with the gradual improvement of the material development, the application range of the material is wider and wider, and the material comprises the fields of food sanitation, medical appliances, small household appliances, aerospace, electronic appliances and the like.

In recent years, especially polyphenylsulfone PPSU and PES, sulfone polymers have been known for their high mechanical strength, heat and oxidation resistance, hydrolysis resistance, and resistance to many acids/bases and solvents. In the application field of food contact products, the product has excellent chemical corrosion resistance, can resist the soaking of general liquid medicine and acid-base liquid, can be washed by detergent and does not generate chemical change; the special characteristics of hot water hydrolysis resistance and superheated steam, the heat resistance temperature is up to 200 ℃, and the repeated high-temperature boiling and steam disinfection can be realized; more importantly, the environment-friendly and environment-friendly composite material does not contain bisphenol A (BPA, environmental hormones and carcinogenic chemical substances disturbing endocrine), conforms to Reach and RoHS rules, is the most ideal and most safe and environment-friendly material which is recommended by the United states, European Union and the like and conforms to infant and food application, has particularly suitable application advantages and prospects, has wide temperature tolerance, can be used in the range of-40-190 ℃, has the retention rate of mechanical performance indexes such as toughness and strength of more than 80 percent, can be used for sterilizing bottles under the condition of high-temperature steam, can be stored for a long time at extremely low temperature, and can not cause the problems of embrittlement, fracture and the like under the low-temperature environment in winter in the north for a long time; in addition, due to its high transparency and excellent colorability, the prepared products are bright and transparent in color, such as baby bottles, coffee machines, cups, non-stick coatings, and the like. Therefore, in recent years, the application and development of the water-based paint are more and more extensive in household kitchens and bathrooms.

Along with the continuous improvement of living standard of people, the demand of families and office places on barreled water is increasing day by day, the barreled water and the water dispenser enter thousands of households and can be seen in public areas such as offices, office buildings, hotels and the like, even in many families, and the barreled water brings convenience and fashion to people. The quality of bottled water is, for various reasons, somewhat problematic. In the barreled water industry, fish eyes are mixed, some fake and fake barreled water appears occasionally, the number of pure water microbial colonies or escherichia coli number seriously exceeds the standard, and some detections exceed the standard by tens of times; the trace elements necessary for human body are obviously less, the conductivity is obviously lower, and the requirement of national standard can not be met at least. All kinds of diseases, due to the annual use of the poor quality barrelled water, cause the increase of tumor diseases and chronic diseases, and influence the physical and mental health of the majority of drinkers to different degrees. The quality problem is many, and quality of service is poor, and safe nothing ensures, has become bottled water trade a big urgent problem of awaiting solution. The barreled water is scientifically selected, which has great significance for improving health.

As the next mainstream drinking water form, the barreled water has obvious advantages compared with the traditional 'plain boiled water'. Firstly, the barreled water is relatively pure and convenient to drink, and can meet the drinking water requirement of relatively concentrating a plurality of mouths; certainly, the defects of the method are not few, the bottled water which is firstly opened needs to be drunk as soon as possible about 15 days, because the bottled water is not live water and bacteria can quickly breed in the water if the bottled water is placed for too long, so that the water quality is polluted, and the problem is that consumers cannot know how long the bottled water is drunk and whether the bottled water is overdue or not; in addition, the market is not standard, and black workshops that the media report that the barreled water is illegally filled are often seen, so that people are not relieved. And illegal operations of dealers and water supply points are avoided, and counterfeit and fake or unqualified purified water is distributed. At present, a large number of unqualified buckets exist in the market, the raw materials of the existing drinking buckets are basically Polycarbonate (PC) or Polyester (PET), but due to the fact that the market competition of barreled water is very strong, some illegal merchants buy the buckets made of inferior raw materials, even waste plastics and compact discs at low price in order to gain violence. Drinking these poor quality barrels of water for a long period of time can also damage the digestive system and nervous system of the human body, causing dizziness, stomachache and even cancer. The used water barrel is recycled and circulated. Is these buckets recycled for repeated use, is absolute disinfection treatment? In the transportation and storage of water, pollution may be brought in by grabbing and squeezing. When the water is improperly placed and exposed to the sun, small molecular substances such as plastic additives and the like can be separated out into water, so that the water quality pollution is aggravated.

General-purpose plastics such as PC or PET are too popular, which results in the unsmooth quality of the products sold on the market, and may contain ingredients with unknown food insecurity, meanwhile, the general-purpose plastics must be added with various modifying aids to be used, including toughening agents, plasticizers, lubricants, toner masterbatch, inorganic and organic fillers, and the like, so as to improve the defects of brittleness, fluidity, color and the like, and with the addition of the aids, various additives containing ingredients with unknown food insecurity are brought, and the risk of food safety and sanitation is also greatly increased.

The PPSU material replaces a barreled water barrel made of PC and PET materials, so that safety risks existing in the water barrel can be perfectly solved, and because the PPSU material is excellent in heat resistance and weather resistance and does not have the problems of aging degradation and the like after being used for a long time, 2, the PPSU material is excellent in hot water resistance and acid and alkali resistance, and can be washed and soaked by hot water or acid and alkali liquor for tens of thousands of times; 3. no modification auxiliary agent is added, so that no micromolecule is separated out into the drinking water, and the water quality safety is ensured; 4. the appearance is transparent and light yellow, the atmosphere is exquisite, the PC or PET material is not needed to be added with toner or color master batch for coloring, and the addition of micromolecules is increased.

More importantly, the preparation of the sulfone polymer must have a very high technical threshold, the threshold is difficult to imitate, the cost is high, only a few companies in the world have production capacity at present, so that counterfeit and shoddy raw materials can be prevented from being used from a material source, and potential safety hazards caused by material problems are fundamentally eliminated.

The main reason for causing quality problems of the barreled water.

1. In the production aspect: (1) in the water source development and water treatment processes, some enterprises which do not have production qualification are mixed in the barreled water market, and in order to earn violence, some illegal manufacturers do not operate according to related regulations, and the quality of the barreled water is reduced because of the fact that the workers are stolen and the materials are falsely lost, or polluted water sources are used, or the production process is not closed. (2) Problems arise during the cleaning and disinfecting process of the tub. At present, most of barrels for barreled purified water are reused, and the common use of a recycling barrel is one of the main reasons for causing the overproof of microorganisms in the purified water. Without subsequent reprocessing, even the otherwise sanitary drums can become contaminated as long as cleaning and sterilization is not amenable to the process. (3) And (5) packaging. The plastic packaged barreled water has the possibility of air entering due to poor sealing and poor material, and toxic and harmful substances in the air pollute the water in the water barrel.

2. Storage and transportation: barreled water is provided for an end user through a water delivery station, and if transportation, storage and loading and unloading are not standard or the water station has other illegal operation behaviors, the water quality can be caused to be in problem. Most barreled water production enterprises 'water delivery' rely on all levels of dealers and water delivery stations to a great extent. At present, most barreled water sales in our province are lack of supervision, the threshold of an agent is very low, and in recent years, a lot of local water stations are complained in a lot of places, such as a water station is suddenly closed, water delivery is not timely, water quality is problematic, a deposit is not returned, a water ticket is wasted, and the like. Moreover, the phenomenon that tap water is used as brand barreled water and fake purified water is used as true purified water occurs when the inferior barrel is used for replacing the brand barrel. It has become a diving rule in the bottled water industry for individual enterprises to replace "PC" (polycarbonate regular barrel material) drinking water barrels with "PET" (irregular barrel material) drinking water barrels. After the PET barrel is used or heated for a long time, some carcinogenic substances can be released by the PET, and the digestion and nervous systems of the human body can be damaged to a great extent.

3. User or home use aspect: problems with barreled water in a user or home typically manifest in two situations: (1) if the water dispenser is not cleaned for a long time, secondary pollution is caused, and (2) the barreled water cannot be drunk up in time, so that pollution is easily caused. Especially mineral water and spring water, the remained water will grow green moss after 3-4 days, which affects water quality.

Based on the above problems, scientific and reasonable countermeasures must be taken to improve. (1) Strict quality and service management control, strict operation rules and quality management are carried out on enterprises engaged in production and operation of drinking water, transparent management and supervision are carried out on the management process of production and circulation of the barreled water, and the management process comprises processing, filling, transportation, circulation, use, auditors in all links and the like of the barreled drinking water, so that users can have right of knowledge and supervise in real time, and the sanitation, safety and health of resident drinking water are ensured. (2) The quality standard of the barreled drinking water is revised, the production standards of various barreled drinking water in the current market are different, the uniform and standard quality standard is not available, and the requirements on the conductivity and the mineral content are different. The national standard is urgently needed to be formed, the supervision is convenient, and the consumer can be ensured to drink the beverage with confidence. (3) The method further enhances the production of the barreled drinking water, the internal management and the external supervision of an enterprise of operation, formulates and implements strict quality management and service standards, enhances the standard assessment and optimal configuration of related professional talents, adopts various effective measures, supervises the production and scientific management of various barreled water drinking production enterprises according to the related national standards, formulates and implements more scientific barreled water delivery service standards, optimizes the service quality and furthest reduces the pollution of the barreled water in various links. (4) The supervision and punishment of all levels of governments and administrative parts are increased, the whole social force is started to effectively supervise and complain the quality of the barreled water, illegal crimes, fake and inferior goods, successful and false marking behaviors of barreled drinking water production and management enterprises are timely checked and released, evidences are found, and related enterprises and personnel are strictly investigated and treated until criminal responsibility is pursued. (5) Guiding and educating the consumers to improve the right-maintaining consciousness and ensure the rights and interests. The method can remind consumers in time to select high-quality production enterprises and brands which are good in credit and have legal operation qualification, pay attention to the identification, the label, the execution standard and the production date (production batch number) when the consumers purchase the barreled water.

To achieve the points, consumers must know safety information of the barreled water in real time, and at the moment, only a display screen is embedded into the barreled water barrel to be transported.

Flexible screens, called OLEDs. The successful mass production of the flexible screen is not only greatly better than the manufacturing of a new generation of high-end smart phone, but also has a profound influence on the application of wearable equipment due to the characteristics of low power consumption and flexibility, and the flexible screen can be widely applied along with the continuous penetration of a personal intelligent terminal in the future. Compared with a traditional screen, the flexible screen has the advantages of being obvious, being lighter and thinner in size and lower in power consumption than original devices, being beneficial to improving the cruising ability of equipment, and meanwhile, based on the characteristics of being bendable and good in flexibility, the durability of the flexible screen is greatly higher than that of the traditional screen, and the probability of accidental damage of the equipment is reduced.

OLEDs are thin and can be mounted on flexible materials such as plastic or metal foils. Instead of glass, plastic can make the display more durable and lighter. The flexible OLED panel is concave from top to bottom with a bending radius of 700 mm.

The OLED adopts a plastic substrate instead of a common glass substrate, and a protective film is adhered to the back surface of the panel by means of a thin film packaging technology, so that the panel can be bent and is not easy to break. The flexible screen can be rolled but cannot be folded, future products can be folded, and the appearance can be changed more.

In short, the OLED display is more and more popular with consumers, and the application field thereof is also more and more extensive.

The OLED display screen is embedded in the barreled water barrel, and when the barreled water barrel is used, the power supply is connected, so that all information of corresponding water can be conveniently inquired, including a water quality monitoring report, a detector, a production date and a use condition, and information required by other customers, such as pictures, videos, advertisements and the like, can also be displayed. When the water is used up, the bucket and the display screen return to the factory together, the display screen is detached before the bucket is cleaned, and after the bucket is filled, the water quality information of the batch is input into the OLED and reloaded, and finally the water quality information is provided for consumers.

Due to the excellent performance and the special practicability of the PPSU and the PES in food contact, the PPSU and the PES have a tendency of being more and more accepted by families on household daily necessities, for example, the invention discloses a wine bottle cap which is made of the PPSU or the PES as a base material, which is a typical application and is a safe and sanitary material, and the problems of embrittlement, fracture and the like can not occur after long-term use in the low-temperature environment in winter in the north. The invention also provides a production process thereof, and belongs to the technical field of manufacturing in the food contact industry. The method conforms to the low-carbon, environment-friendly, healthy, sanitary and green life concept and life style which are more and more emphasized and advocated by people.

The prepared barreled water barrel has the advantages of exquisite and large appearance, high-efficiency anti-counterfeiting performance, production by a general injection molding machine and the like due to the fact that the sulfone polymer is called as 'gold plastic', is convenient to use by a user, is easy to distinguish, can be matched with colors according to needs, and is exquisite and large in appearance.

The invention discloses a barreled water bucket made of PPSU or PES, which is light amber full transparent resin, is not added with any modification auxiliary agent, is made of pure resin, and overcomes the use defects of the existing material such as food sanitation safety risk, mechanical safety risk and the like. The invention also provides a production process of the bucket, which is suitable for industrial production.

The produced barreled water barrel can be recycled after being used as engineering materials to produce engineering parts such as gears, valve plates and the like. The material becomes a new high-performance material which can be recycled, and the problem of pollution caused by waste or garbage is avoided.

The barreled water bucket made of the PPSU or PES base material is not decomposed at a high temperature below 190 ℃, can be repeatedly sterilized at a high temperature, has no volatilization of harmful substances, has smooth surface, acid and alkali resistance, corrosion resistance, wear resistance, difficult residual bacteria, no mildew and difficult scald when in use, and is a sanitary and safe tableware. Based on the characteristics, the PPSU or the PES is used as the base material, and the barreled water barrel can be prepared, so that the special adaptability is realized.

The patent that has not seen the drinking water barreled cask that has disclosed used PPSU or PES as the substrate before, this patent belongs to the original patent, uses PPSU pure resin or PES pure resin, solves a great deal of problems that current barreled cask exists well, eliminates the potential safety hazard.

No patent publication of barreled water with sulfone material as base material is found. The barreled water made of other materials is usually blended and added with an antibacterial agent to realize the antibacterial performance, the commonly used antibacterial agent is basically a metal ion antibacterial agent containing Ag, Zn, Au and the like, is an effective antibacterial agent and also belongs to a commonly used antibacterial agent blended into a high polymer material, only van der Waals force coexists with a high polymer material substrate and is easy to migrate, and when the material containing Ag is used for a long time, Ag + is released and possibly enters a human body, so that the concentration of silver ions in the human body is increased to cause systemic side effects.

Chlorphenisin (Chlorophenesin) with molecular formula of C₉H₁₁O₃Cl, molecular weight 202.635, alias names including: 3-p-chlorophenoxy-1, 2-propanediol; chlorobenzene, monochlorobenzene; 3- (4-chlorophenoxy) -1, 2-propanediol in the form of white to off-white crystalline powder, commonly used as preservativeWidely used in cosmetics, compatible with most preservatives (including potassium sorbate, sodium benzoate, methylisothiazolinone).
