Description

Technical Field

[0001] The invention relates to the technical field of microwave absorbing materials, and in particular to a fully open-pore water-resistant microwave absorbing material and a manufacturing process thereof. Background Art

[0002] Microwave absorbing material sheets are widely used in the field of electronic products. Electronic products are increasingly developing towards intelligence, integration, lightness, and multi-functions. With the increase in circuit board integration and the improvement in data transmission speed, the heat generated by electronic devices such as chips is getting higher and higher, and the components on the circuit board often cause electromagnetic interference to adjacent components, resulting in electronic products using up power too quickly, operating failures, slow running, etc. Therefore, absorbing material sheets are often applied to electronic components.

[0003] The existing technology has the following problems:

[0004] 1. The existing fully open-pore water-resistant microwave absorbing materials have low microwave absorption efficiency, and some microwaves will pass through the fully open-pore water-resistant microwave absorbing materials and affect other electronic devices;

[0005] 2. When the fully open-pore water-resistant microwave absorbing material is bent, the fully open-pore water-resistant microwave absorbing material often cracks, thereby causing damage to the fully open-pore water-resistant microwave absorbing material;

[0006] 3. The existing fully open-pored water-resistant microwave absorbing materials have complex process flows during the production process, which greatly reduces the production efficiency of the fully open-pored water-resistant microwave absorbing materials and increases the loss of raw materials required for the production of the fully open-pored water-resistant microwave absorbing materials. Summary of the invention

[0007] The present invention provides a fully open-pore water-resistant microwave absorbing material and a manufacturing process thereof to solve the problems raised in the above background technology.

[0008] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0009] In the first aspect, the present invention provides a fully open-pore water-resistant microwave absorbing material, comprising a first microwave absorbing cone layer, the lower surface of which is fixedly connected to a first microwave absorbing plate layer, the lower surface of which is fixedly connected to a first microwave emitting plate layer, the lower surface of which is fixedly connected to a guide reinforcement plate layer, the lower surface of which is fixedly connected to a second microwave emitting plate layer, the lower surface of which is fixedly connected to a second microwave emitting plate layer, the lower surface of which is fixedly connected to a second microwave absorbing plate layer, and the lower surface of which is fixedly connected to a second microwave absorbing cone layer.

[0010] A further improvement of the technical solution of the present invention is that the guide reinforcement plate layer includes a reinforcement plate layer, the back side of the reinforcement plate layer is fixedly connected to the upper surface of the second microwave emitting plate layer, a circular guide hole is opened in the horizontal direction of the front side of the reinforcement plate layer, and a hexagonal guide hole is opened in the vertical direction of the front side of the reinforcement plate layer.

[0011] The above-mentioned technical scheme is adopted, and the reinforcement plate layer, hexagonal guide holes, and circular guide holes in the scheme cooperate with each other to reinforce the interior of the fully-open-pore water-resistant microwave absorbing material, prevent the fully-open-pore water-resistant microwave absorbing material from cracking when the fully-open-pore water-resistant microwave absorbing material is bent, and divert the water entering the interior of the fully-open-pore water-resistant microwave absorbing material, thereby improving the drainage effect of the fully-open-pore water-resistant microwave absorbing material and preventing water from entering the fully-open-pore water-resistant microwave absorbing material and being unable to dry for a long time.

[0012] In a second aspect, the present invention further provides a process for manufacturing a fully open-pore water-resistant microwave absorbing material, the process for manufacturing a fully open-pore water-resistant microwave absorbing material comprising the following steps:

[0013] Step 1: Weigh and classify the raw materials;

[0014] Step 2: Mix the classified raw materials separately;

[0015] Step 3: extrusion molding;

[0016] Step 4: Material splicing;

[0017] Step 5: Drying and cooling;

[0018] Step 6: Packing and storage.

[0019] A further improvement of the technical solution of the present invention is that: the step 1 comprises: classifying and stacking the weighed raw materials, namely:

[0020] A1. Microwave absorbing materials: materials that are easy to absorb microwaves, and are also the main materials required for the manufacture of fully open-pore water-resistant microwave absorbing materials;

[0021] A2. Microwave reflecting materials: They are used to emit the microwaves that have passed through the microwave absorbing material but have not been absorbed, so that the microwave absorbing material can absorb the microwaves for the second time.

[0022] A3. Reinforcement materials: materials used to reinforce the middle part of the fully open-pored water-resistant microwave absorbing material to avoid breakage when the fully open-pored water-resistant microwave absorbing material is bent.

[0023] The adoption of the above technical solution makes it easier to classify and process the raw materials, thereby improving the production efficiency of the fully open-pore water-resistant microwave absorbing material.

[0024] A further improvement of the technical solution of the present invention is that: the step 2 comprises: symmetrically taking the classified raw materials and mixing them separately to make the raw materials evenly mixed, and the mixing time is 0.5-1h.

[0025] By adopting the above technical scheme, the raw materials are classified and evenly tempered, thereby improving the microwave absorption efficiency of the fully open-pore water-resistant microwave absorbing material.

[0026] The further improvement of the technical solution of the present invention is that: the step three comprises: extruding the raw materials after being mixed evenly, and respectively extruding the raw materials into:

[0027] B1. Plate with cone: The evenly mixed microwave absorbing raw materials are extruded into a plate with cone by using a mold;

[0028] B2. Flat plate: Use a mold to extrude the evenly mixed microwave emitting raw materials into a plate with a relatively flat surface;

[0029] B3. Plates with flow guide holes: Use a mold to extrude the evenly mixed reinforcement raw materials into plates with flow guide holes.

[0030] The adoption of the above technical scheme makes it easier to process the raw materials, reduces the technical requirements for the production and processing of the fully open-pore water-resistant microwave absorbing material, and facilitates the processing of the fully open-pore water-resistant microwave absorbing material.

[0031] A further improvement of the technical solution of the present invention is that the step four comprises: using an adhesive material to sequentially splice the extruded raw materials to form a prototype of a fully open-pore water-resistant microwave absorbing material.

[0032] By adopting the above technical scheme, the qualified rate of the fully open-pore water-resistant microwave absorbing material after production is improved, thereby reducing the cost required for the production of the fully open-pore water-resistant microwave absorbing material.

[0033] A further improvement of the technical solution of the present invention is that the step five comprises:

[0034] C1. Using a heating device to heat the fully open-pored water-resistant microwave absorbing material prototype to remove moisture from the fully open-pored water-resistant microwave absorbing material prototype, so that the raw materials in the fully open-pored water-resistant microwave absorbing material prototype are mutually adsorbed to form a fully open-pored water-resistant microwave absorbing material, the heating temperature is 55-75 degrees, and the heating time is 2-3 hours;

[0035] C2. Use cooling equipment to cool the fully open-pore water-resistant microwave absorbing material to reduce its temperature to 20-25 degrees, and the cooling time is 1-1.5 hours.

[0036] By adopting the above technical scheme, the molecular structures inside the prototype of the fully open-pored water-resistant microwave absorbing material are adsorbed to each other to form the material.

[0037] A further improvement of the technical solution of the present invention is that step six includes: after testing the fully open-pore water-resistant microwave absorbing material after processing, the open-pore water-resistant microwave absorbing material is packaged, and then the open-pore water-resistant microwave absorbing material is placed in a warehouse for storage.

[0038] By adopting the above technical scheme, the qualified rate of the fully open-pore water-resistant microwave absorbing material after processing is judged, thereby achieving the effect of controlling the quality of the fully open-pore water-resistant microwave absorbing material after production.

[0039] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0040] 1. The present invention provides a fully open-pored water-resistant microwave absorbing material and a manufacturing process thereof. The first microwave absorbing cone layer, the first microwave absorbing plate layer, the first microwave emitting plate layer, the second microwave emitting plate layer, the second microwave absorbing plate layer and the second microwave absorbing cone layer cooperate with each other. Most of the microwaves entering the fully open-pored water-resistant microwave absorbing material are absorbed by the first microwave absorbing plate layer and the second microwave absorbing plate layer. At the same time, the first microwave absorbing cone layer and the second microwave absorbing cone layer are used to reduce the refraction of microwaves after impacting the fully open-pored water-resistant microwave absorbing material. The first microwave emitting plate layer and the second microwave emitting plate layer are used to emit microwaves passing through the outer wall of the first microwave absorbing plate layer and the second microwave absorbing plate layer, so that the microwave absorbing material absorbs the microwaves again, thereby improving the absorption efficiency of the fully open-pored water-resistant microwave absorbing material, reducing the influence of microwaves on surrounding buffers, and avoiding the problem that microwaves generated between electronic devices interfere with microwaves generated by other electronic devices.

[0041] 2. The present invention provides a fully-open-pore water-resistant microwave absorbing material and a manufacturing process thereof. The reinforcing plate layer, the hexagonal guide holes, and the circular guide holes cooperate with each other. The inside of the fully-open-pore water-resistant microwave absorbing material is reinforced by the reinforcing plate layer to prevent the fully-open-pore water-resistant microwave absorbing material from cracking when being bent, thereby preventing the fully-open-pore water-resistant microwave absorbing material from being unable to be used normally. The hexagonal guide holes and the circular guide holes are used to guide water entering the fully-open-pore water-resistant microwave absorbing material, thereby improving the drainage effect of the fully-open-pore water-resistant microwave absorbing material and preventing water from entering the fully-open-pore water-resistant microwave absorbing material and failing to dry for a long time, thereby affecting the microwave absorption effect of the fully-open-pore water-resistant microwave absorbing material.

[0042] 3. The present invention provides a fully-open-pore water-resistant microwave absorbing material and a manufacturing process thereof. Through the method of classified processing, it is convenient to carry out assembly line processing on the fully-open-pore water-resistant microwave absorbing material during production, thereby improving the production efficiency of the fully-open-pore water-resistant microwave absorbing material and greatly reducing the time required for the production of the fully-open-pore water-resistant microwave absorbing material. At the same time, it avoids the waste of raw materials caused by the original complicated process flow, greatly improves the processing effect of the staff through the reasonable allocation of labor, and greatly reduces the production and processing cost of the fully-open-pore water-resistant microwave absorbing material.
