Technical Field
The utility model relates to a high-strength cushion pad, and belongs to the technical field of materials.
Background
In the process of manufacturing a laminate such as a printed circuit board, in the step of press forming and thermocompression bonding, a laminate material to be pressed is sandwiched between hot plates serving as a heating and pressing mechanism, and a certain pressure and heat are applied. In order to obtain a molded article with high accuracy, it is necessary to perform hot pressing by interposing a flat plate-like cushioning material between a hot plate and a laminate material in order to uniformize the heat and pressure applied to the laminate material over the entire surface in the hot pressing.
Conventionally, a paper material in which about 3 to 20 pieces of kraft paper or linter paper are laminated has been used as a hot press cushioning material in many cases. A paper-made cushioning material is inexpensive, and has well-balanced physical properties in terms of cushioning properties, in-plane uniformity, and heat transfer properties. However, the paper-made cushioning material has a disadvantage that it cannot be repeatedly used in a plurality of presses because it has no restoring force of voids after pressing and further constituent fibers are thermally deteriorated.
The utility model application with application number 201911210682.8 discloses a novel cushion pad, which sequentially comprises the following components from top to bottom: the surface layer comprises a polytetrafluoroethylene layer, a glass fiber cloth layer and a fluororubber layer with air holes inside; the first thick cloth layer is prepared by soaking glass fiber cloth in liquid fluororubber and curing; a first thin cloth layer which is made of fluororubber containing air holes inside; a second thick cloth layer; a second thin cloth layer; a third thick cloth layer; a third thin cloth layer; a fourth thick cloth layer; a fourth fabric layer; a fifth thick cloth layer; a fifth cloth layer; and a sixth thick cloth layer. The novel cushion pad is composed of glass fiber and fluororubber containing air holes, has the outstanding advantages of excellent cushion performance, good heat resistance (capable of being used at high temperature of 240 ℃ for a long time), low deformation rate and the like, and is a high-performance cushion pad material superior to the traditional press-fit pad and kraft paper.
However, the cushion pad in the prior art has the defects of complex structure, high production cost, unstable performance and the like.

In another embodiment of the present invention, each of the first and second cloth layers includes a basalt fiber cloth surface layer and a fluororubber inner layer, or a polyester silicone resin surface layer, a basalt fiber cloth intermediate layer, and a fluororubber inner layer.
Further, the thickness and the weight of each thick cloth layer are equal or unequal, and the thickness and the weight of the first thin cloth layer and the second thin cloth layer are equal; the ratio of the thickness of any thick cloth layer to the thickness of the first thin cloth layer and the second thin cloth layer is 2.5-5; the ratio of the weight of any thick cloth layer to the weight of the first thin cloth layer and the second thin cloth layer is 3-5.5.
Furthermore, the continuous thick cloth layer is four layers, namely a first thick cloth layer, a second thick cloth layer, a third thick cloth layer and a fourth thick cloth layer from top to bottom in sequence; the first thick cloth layer is connected with the inner layer of the fluororubber in the first thin cloth layer; the fourth thick cloth layer is connected with the inner layer of the fluororubber in the second thin cloth layer.
Furthermore, the continuous thick cloth layer comprises six layers, namely a first thick cloth layer, a second thick cloth layer, a third thick cloth layer, a fourth thick cloth layer, a fifth thick cloth layer and a sixth thick cloth layer from top to bottom in sequence; the first thick cloth layer is connected with the inner layer of the fluororubber in the first thin cloth layer; the sixth thick cloth layer is connected with the fluorine rubber inner layer in the second thin cloth layer.
Further, the polyester silicone surface layer is arranged above the glass fiber cloth middle layer, and part of the polyester silicone penetrates into the glass fiber cloth middle layer; the inner fluororubber layer is arranged below the glass fiber cloth middle layer, and part of fluororubber permeates the glass fiber cloth middle layer.
