Description

Pressure storage bucket with thermoplastic elastic separation membrane

The present invention relates to a pressure storage bucket having a thermoplastic elastic separation membrane, and more particularly to a pressure storage bucket having a odorless, recyclable and non-vulcanizable thermoplastic flexible separation membrane.

After reverse osmosis (RO) or other water filters are used for water filtration, the filtered water is flowed into the pressure storage tank for water storage. The pressure storage tank is covered by an upper cover and a lower cover. The cover is formed to form an internal space having a diaphragm for partitioning the internal space into a water storage area and a gas storage area, and the diaphragm is made of a rubber material and has a deformability; when needed When filtering the water, it is only necessary to open the water outlet of the upper cover, and the filter water which is deformed by the pressure balance and squeezes the water storage area is discharged from the water outlet of the upper cover.

Because the diaphragm used for the pressure storage tank needs to have good airtightness and water tightness, the prior art membranes are mostly made of butyl rubber, wherein the butyl rubber is passed through a thermoforming machine or a rubber injection molding machine. After injection molding, in order to strengthen the hardness and strength of the butyl rubber, it must be sulphurized in a high temperature and high pressure environment. However, the butyl rubber which has been sulphurized not only produces odor, but also changes its molecular structure to a network polymer (net). Polymer) loses its plasticity and becomes a thermosetting rubber, so that the separator cannot be recycled and reused; and in order to solve the disadvantage that the separator is odor-prone in use, the prior art processes the separator by secondary vulcanization, wherein The secondary sulfurization treatment must be carried out at a high temperature, which has the disadvantages of being time consuming and energy consuming.

In view of the fact that the prior art membrane is apt to produce odor and cannot be recycled and reused, the purpose of the present invention is to provide a pressure storage bucket having a thermoplastic elastic separation membrane which does not require vulcanization treatment and thus has no odor and has The advantages of recycling can be reused.

In order to achieve the above object, the present invention provides a pressure water storage bucket having a thermoplastic elastic separation membrane, wherein the pressure storage water tank comprises a cover body, a base and a separation membrane; the cover body comprises a water storage material capable of accommodating the filtered water. a space and a water inlet and outlet connected to the water storage space; the base includes a gas-receiving space for accommodating the gas and an air inlet communicating with the gas-filling space, and the base is covered with the cover body; The separation film is disposed between the cover body and the base to partition the water storage space and the gas tolerance space, and the separation film is a thermoplastic elastomer comprising styrene ethylene/butylene styrene block copolymer (styrene ethylene) /butylene styrene block copolymer, SEBS block copolymer) and polypropylene (PP).

According to the present invention, the separator film styrene ethylene/butylene styrene block copolymer and polypropylene may be mixed in an appropriate ratio as needed.

Preferably, the separation film is obtained by plastic injection molding, which comprises: after melting the raw material at a high temperature, injecting the raw material into a mold by pressure, and after cooling forming, the above system is prepared. There is no need to add sulfur in the process.

Preferably, the cover body and the base are composed of polypropylene as a raw material.

The pressure storage water tank of the present invention has a thermoplastic elastic separation membrane, wherein the separation film is obtained by blending a styrene ethylene/butylene styrene block copolymer with polypropylene, and is prepared by plastic injection. Light weight (about 0.9), no phthalate salt, and good compatibility with the cover and base formed from polypropylene as raw material, and fully compatible, making the thermoplastic thermoplastic elastic separator The pressure storage bucket can directly pulverize the pressure storage bucket without disassembling, so that the separation membrane, the cover body and the base can be recycled and reused; and the separation membrane does not need to be added with sulfur treatment in the process, so that the separation membrane has no odor. Therefore, the disadvantages of the prior art requiring secondary sulfurization treatment can be improved.

The separator film comprises a styrene ethylene/butylene styrene block copolymer and a polypropylene obtained by plastic injection molding, and the process does not require sulfur addition, and when the materials of the cover body, the base and the separation film are similar (including Polypropylene), when the cover body, the base, and the separation film are fused to each other, the bonding property is good, and thus the product has high airtightness.

As shown in FIG. 1, the pressure water storage tank 1 having the thermoplastic elastic separation membrane 1 includes a cover body 10, a base 20 and a separation film 30. The cover body 10 includes a water storage space 11 for accommodating filtered water and an inlet and outlet port 12 communicating with the water storage space 11;

The base 20 includes a gas-receiving space 21 for accommodating a gas, and an air inlet 22 communicating with the gas-filling space 21, and the base 20 is covered with the cover body 10;

The partition film 30 is disposed between the cover 10 and the base 20 to partition the water storage space 11 of the cover 10 and the air space 21 of the base 20. The separation film 30 is a thermoplastic elastomer containing benzene. Ethylene ethylene/butylene styrene block copolymer and polypropylene.

The separating film 30 is obtained by plastic injection molding of the above raw materials, and the steps include: after melting the raw materials at a high temperature, injecting the raw materials into a mold by pressure, and preparing the materials after cooling, wherein the above The separation film formed in the production process is odorless and odorless, and still has good elasticity, so that the pressure water storage tank 1 can stably and continuously output the filtered water stored in the water storage space 11.

When the present invention is used, as shown in FIG. 2, the filtered water of the reverse osmosis or other water filter is introduced into the water storage space 11 of the cover body 10 through the water inlet and outlet 12 of the cover body 10, and then the filtered water is used. The inlet and outlet port 12 of the lid body 10 is opened, and the diaphragm 30 is deformed by pressure equalization and the water storage space 11 is squeezed, so that the filtered water is discharged from the inlet and outlet port 12 of the lid body 10.
