TECHNICAL FIELD

[0001] The utility model belongs to wave -absorbing material technical field, specifically relates to a carbon titanium base wave -absorbing rubber patch. BACKGROUND

[0002] With the rapid development of electronic technology, mobile communication, computer and household appliance and other electronic products are increasingly popular, and people's living environment is suffering from increasingly serious electromagnetic pollution. At the same time, the increasing number of high-rise buildings in the city further deteriorates the electronic environment. Reducing electromagnetic interference has become the focus of global electronic industry. As a kind of material that can convert electromagnetic wave into other forms of energy, wave -absorbing material can effectively control its propagation, reduce reflection and suppress interference, thereby playing an important role in electromagnetic wave management.

[0003] However, the application of wave -absorbing material at present mainly concentrates in high -end field, and the popular field is less applied. The reason is that the existing wave -absorbing material is mostly expensive, and is usually customized design for specific application, and presents the characteristics of 'one thing one use one design'. This not only consumes a lot of manpower and material resources, but also limits its application in wider field. In engineering application, in addition to requiring wave -absorbing material to have high absorption rate to electromagnetic wave in a wide frequency band, it also requires it to have light weight, high temperature resistance, moisture resistance, corrosion resistance and other excellent properties. INVENTION CONTENTS

In addition, the material can be recycled after use, which not only meets the environmental protection concept, but also reduces the use cost. More importantly, it has wave -absorbing, light weight, high temperature resistance, moisture resistance, corrosion resistance, self -cleaning and other excellent properties, which can meet the strict requirements of wave -absorbing material in engineering application, daily life and other fields, and play the role of controlling electromagnetic wave propagation, reducing reflection and suppressing interference.

[0005] In order to achieve the above-mentioned purpose of the application, the utility model provides a kind of carbon titanium base wave-absorbing rubber paste, which is composed of first structure layer, second structure layer, third structure layer, fourth structure layer and fifth structure layer;The first structure layer is the middle layer, and the upper and lower sides thereof are the second structure layer and the third structure layer respectively, the side of the second structure layer away from the first structure layer is the fourth structure layer, and the side of the third structure layer away from the first structure layer is the fifth structure layer;The upper and lower surfaces of the first structure layer are tightly connected with the second structure layer and the third structure layer respectively, the other side of the second structure layer is tightly connected with the fourth structure layer, and the other side of the third structure layer is tightly connected with the fifth structure layer;The first structure layer is a wave-absorbing rubber layer, the second structure layer and the third structure layer are temperature-resistant and corrosion-resistant layers, and the fourth structure layer and the fifth structure layer are hydrophobic and oleophobic self-cleaning coatings.

The second structure layer and the third structure layer are polyurethane films containing hydrated titanium dioxide, i.e. mixed films of hydrated titanium dioxide and polyurethane; wherein the polyurethane is a solvent, and the titanium dioxide plays a functional role.

[0007] By adopting the above-mentioned structure design scheme of carbon titanium base wave-absorbing rubber paste, the wave-absorbing layer, temperature-resistant and corrosion-resistant film layer and self-cleaning film layer are arranged in sequence from the center to the outside in a central symmetric manner.

The thickness of this structure layer is prepared according to demand and is not limited.

[0009] Further, the second structure layer and the third structure layer are respectively arranged on the surface of the first structure layer by magnetron sputtering technology.

The drawings are only schematic and do not represent the shape and thickness of the structure layers.

The thickness of the structure layer is not limited and can be prepared according to requirements.

[0013] The second structure layer and the third structure layer are temperature-resistant and corrosion-resistant film layers. A titanium dioxide hydrate solution with a concentration of 0.5-2 mol / L is dispersed in polyurethane varnish with a mass fraction of 20%-40%, and then the second structure layer and the third structure layer are respectively formed on the upper and lower surfaces of the first structure layer by magnetron sputtering technology. The thickness of the second structure layer and the third structure layer is 100-500 μm. After the second structure layer and the third structure layer are dried, the next structure layer is constructed.

[0014] The fourth structure layer and the fifth structure layer are self-cleaning film layers, which are mainly hydrophobic and oleophobic self-cleaning transparent coatings. Raw materials can be directly purchased from the market. The self-cleaning coating is formed on the surface of the second structure layer and the third structure layer by magnetron sputtering or coating technology to form a transparent network hydrophobic and oleophobic layer. The thickness of the fourth structure layer and the fifth structure layer is 50-200 μm.

[0015] The carbon titanium-based wave-absorbing rubber patch is made, and when applied, a suitable colloid is selected to adhere the rubber patch to a device or equipment that needs to be applied; the rubber patch can be cut and trimmed according to the needs of the application scene to facilitate adhesion and use.

The first structure layer deeply integrates the characteristics of the wave-absorbing material and the rubber, which not only facilitates the user to cut according to the actual use demand, but also effectively reduces or even avoids the interference of electromagnetic waves. The second structure layer and the third structure layer significantly improve the temperature resistance and corrosion resistance of the material, so that it can maintain stable performance in complex environments. The fourth structure layer and the fifth structure layer endow the material with self-cleaning ability, which can effectively prevent water and dirt, further enhance the practicality and durability of the material, and also have many excellent properties such as wave-absorbing, light weight, temperature resistance, humidity resistance, corrosion resistance, etc.
