Description

Technical Field

[0001] The invention belongs to the technical field of metal plates, and specifically refers to a metal plate that releases negative ions and a processing technology. Background Art

[0002] In modern society, people pay more and more attention to a healthy and comfortable living environment. As a substance beneficial to the human body and the environment, negative ions have received widespread attention. Studies have shown that negative ions have many positive effects. They can combine with positively charged dust, smoke, bacteria and other particles in the air, causing these particles to condense into groups and settle, thereby purifying the air. At the same time, negative ions can also enter the human body through breathing and have a positive effect on the physiological functions of the human body, such as improving cardiopulmonary function, enhancing human immunity, and relieving fatigue.

[0003] In the existing technical field, there are mainly the following ways to generate and utilize negative ions. On the one hand, there are independent negative ion generators, which usually require an external power supply and are placed in a specific location. Their usage scenarios are greatly limited, and the negative ions in the overall space are unevenly distributed, making it difficult to achieve all-round air optimization. On the other hand, although some materials also have a certain ability to release negative ions, there are problems such as unstable release, short service life, or poor compatibility with other materials.

[0004] In many fields such as building decoration, furniture manufacturing and vehicle interior, metal sheet is a widely used basic material. However, traditional metal sheet only has basic physical properties, such as strength and hardness, but does not have the functional characteristic of releasing negative ions. This makes it impossible to enjoy the benefits of negative ions in an environment where metal sheets are used as decorative or structural materials. With the improvement of people's requirements for environmental quality, there is an urgent need for a new material that can combine the excellent physical properties of metal sheets with the negative ion release function to meet the needs of improving environmental quality in different scenarios. The metal sheet and processing technology for releasing negative ions of the present invention are produced based on such market and technical background. Summary of the invention

[0005] The purpose of the present invention is to provide a metal plate material and a processing technology for releasing negative ions. The metal plate material in the present invention can continuously and stably release negative ions, which can effectively improve the surrounding air environment and improve the air quality. It can reduce dust absorption and reduce bacterial growth when applied in the fields of interior decoration. The processing technology of the present invention is simple and easy to operate. Different base metal plates and negative ion releasing layer materials can be selected according to actual needs to adapt to various production scales and application scenarios. The metal plate material of the present invention is similar to ordinary metal plates in appearance and can be widely used as decorative materials in the fields of construction, furniture, and transportation. It will not have a significant impact on the original design style, and at the same time, it has the unique advantage of increasing the negative ion releasing function.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a metal plate material for releasing negative ions and a processing technology, wherein the metal plate material is composed of a base layer, a negative ion releasing layer and a protective layer.

[0007] Furthermore, the base layer is composed of one or more of stainless steel, aluminum alloy and galvanized steel plate.

[0008] Furthermore, the negative ion releasing layer comprises the following components in parts by weight: 20-100 parts of negative ion generating material, 1-20 parts of binder, 1-20 parts of dispersant, and 2-30 parts of stabilizer.

[0009] Preferably, the negative ion releasing layer comprises the following components in parts by weight: 50-90 parts of negative ion generating material, 2-8 parts of binder, 1-5 parts of dispersant, and 3-7 parts of stabilizer.

[0010] Furthermore, the negative ion generating material consists of tourmaline powder and quartz powder.

[0011] Furthermore, the adhesive includes one or more of silicone resin, epoxy resin and polyurethane resin.

[0012] Furthermore, the dispersant includes one or more of lignin sulfonate, polycarboxylate, polyethylene glycol and fatty alcohol polyoxyethylene ether.

[0013] Furthermore, the stabilizer includes one or more of dibasic lead phosphite, dibutyltin maleate and rare earth stabilizers.

[0014] The present invention also provides a processing technology for a metal plate that releases negative ions, and the processing technology comprises the following steps:

[0015] (1) Use ultrasonic cleaning to clean the surface of the base metal plate to remove oil, impurities, etc. on the surface; the ultrasonic cleaning frequency is 20-50kHz, and the cleaning time is 5-15 minutes. Rinse the cleaned metal plate with clean water and dry it.

[0016] (2) Mix the negative ion powder and the binder in a predetermined ratio, stir them in a mixer at a speed of 50-200 rpm for 20-60 minutes to fully mix the two, and then add a proper amount of diluent to adjust the viscosity of the mixture for subsequent coating operations. The diluent can be an organic solvent or water that matches the binder, and the added amount accounts for 10%-30% of the total mass of the mixture.

[0017] (3) Spraying the negative ion release layer mixture onto the pretreated base metal plate, with the coating thickness controlled between 0.05 mm and 0.5 mm; after coating, the metal plate is placed in a curing furnace for curing. The curing allows the negative ion release layer to be firmly attached to the base metal plate, forming a stable metal plate that releases negative ions.

[0018] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The metal plate in the present invention can continuously and stably release negative ions, which can effectively improve the surrounding air environment and improve the air quality. When used in fields such as interior decoration, it can reduce dust absorption and reduce bacterial growth; (2) The processing technology of the present invention is simple and easy to operate. Different base metal plates and negative ion release layer materials can be selected according to actual needs to adapt to a variety of production scales and application scenarios; (3) The metal plate of the present invention is similar to ordinary metal plates in appearance and can be widely used as decorative materials in the fields of construction, furniture, and transportation. It will not have a significant impact on the original design style, while adding the unique advantage of negative ion release function. BRIEF DESCRIPTION OF THE DRAWINGS
