Embodiment 1
[0032] The suction material device of the present invention comprises a suction part and a closing part. The suction part is composed of a substrate and a magnet embedded in the substrate. The magnets are distributed in parallel in several rows and columns in the substrate. A magnet / iron sheet combination is embedded on one side. The joint part is composed of a base plate and an iron sheet embedded in the base plate.
[0033] refer to figure 1 , the manufacturing method of the suction device material comprises the following steps:
[0034] 1. Mix 133g of bisphenol A epoxy resin, 5.7g of four-functional epoxy resin, 2.8g of electronic grade dicyandiamide, 0.046g of dimethylimidazole, 20g of 10 micron aluminum hydroxide, and 30g of dimethylformamide into a gel Glue with a time of 250-255 seconds;
[0035] 2. After the 7628 cloth and 2116 cloth are impregnated with the glue solution, put them into an oven at a temperature of 180°C-220°C to bake, and then cool to obtain 7628 w...

[0049] refer to figure 1 , the manufacturing method of the suction device material comprises the following steps:
[0050] 1. Mix 133g of bisphenol A epoxy resin, 5.7g of four-functional epoxy resin, 2.9g of electronic grade dicyandiamide, 0.046g of dimethylimidazole, 20g of 10 micron aluminum hydroxide, and 29g of dimethylformamide into a gel Glue with a time of 250-255 seconds;
[0051] 2. After the 7628 cloth is impregnated with the glue solution, put it into an oven at a temperature of 180°C-220°C to bake, and then cool to obtain a 7628 cloth prepreg with a gel time of 120-125 seconds and a resin content of 44.1%-44.9%. Cut the 7628 cloth prepreg to the required size;
[0052] 3. When matching, stack four 7628 cloth prepregs together;
[0053] 4. Cover both sides of the laminated prepreg in step 3 with a release film, and then put a certain number of laminated plates and stainless steel plates into a vacuum press for pressing, at 100°C- Pressing is carried out between...
Embodiment 3
[0065] refer to figure 1 , the manufacturing method of the suction device material comprises the following steps:
[0066] 1. Mix 133g of bisphenol A epoxy resin, 5.7g of four-functional epoxy resin, 2.8g of electronic grade dicyandiamide, 0.044g of dimethylimidazole, 20g of 10 micron aluminum hydroxide, and 30g of dimethylformamide into a gel Glue with a time of 253-258 seconds;
[0067] 2. After the 7628 cloth and 1506 cloth are impregnated with the glue solution, put them into an oven at a temperature of 180°C-220°C to bake, and then cool to obtain the 7628 cloth with a gel time of 122-127 seconds and a resin content of 44.1%-44.9%. Cloth prepreg and 1506 non-preg with a gel time of 122-127 seconds and a resin content of 42.6%-43.4%, cut the 7628 cloth prepreg and 1506 cloth prepreg into the required size;
[0068] 3. When matching, stack four 7628 cloth prepregs together;
[0069] 4. Cover both sides of the laminated prepreg in step 3 with a release film, then laminate...
