Detailed Description
The present invention will be described in detail with reference to specific examples, but the present invention is not limited to these examples.
As shown in FIG. 1, an example of a structure of a mica board product with blind holes is shown, and the structure comprises three different types of blind holes, and the manufacturing method provided by the method of the invention relates to three types of blind hole models including but not limited to blind holes with any geometric shapes. The thickness of the mica plate product is between 0.2 and 30mm, and the depth of the blind hole is between 0.1 and 29.9 mm.
Examples
As shown in fig. 2, the present embodiment provides a method for manufacturing a mica plate with blind holes, which includes the following steps:
(1) according to the length and width of the appearance of a mica plate product, a large piece of mica paper raw material (the mica paper contains glue which is dried, and the thickness of the mica paper is between 0.01mm and 0.15 mm) is cut into a plurality of small-sized mica paper according to the size requirement, and the size needs to be kept with a proper allowance, so that the appearance can be conveniently cut by a rear machine. Then, according to the thickness requirement of the mica plate product, a plurality of mica paper are stacked to form a first mica paper raw material and a second mica paper raw material, wherein the thicknesses of the first mica paper raw material and the second mica paper raw material can be the same or different, and are specifically determined according to the specification of the mica plate product.
(2) The first mica paper raw material is hot-pressed by a hot press, the hot-pressing temperature is set between 100 ℃ and 300 ℃, the pressure is set between 0MPa and 40MPa, the hot-pressing time is set between 0.1 hour and 20 hours (the hot-pressing time is influenced by the hot-pressing product quantity, the strength of the mica plate and other performance requirements), the first mica plate is formed after the hot pressing is finished, and a plate-shaped structure with a certain thickness is formed, as shown in fig. 3. Wherein, the thickness of the first mica plate is equal to the depth of the blind hole.
(3) And machining the second mica paper raw material, and manufacturing a through hole by a machining method according to the shape and the size and the position requirements of the blind hole of the finished mica plate, wherein the front projection shape and the position requirements of the through hole are the same as those of the blind hole. The second mica paper stock is processed to make through holes by means of cutting die punching, stamping, laser cutting and the like, but is not limited to these means. After machining is complete, a third mica paper stock with through holes is formed, as shown in FIG. 4.
(4) The first mica plate and the third mica paper raw material which are single-piece are stacked together according to the size requirement of the mica plate product, the first mica plate and the third mica paper raw material are put into a hot press for hot pressing, the hot pressing temperature is set between 100 ℃ and 300 ℃, the pressure is set between 0MPa and 40MPa, the hot pressing time is set between 0.1 hour and 20 hours, the first mica plate and the third mica paper raw material are hot pressed together to form a whole plate, namely a second mica plate, and the second mica plate has the shape of blind holes, as shown in figure 5.
