Embodiment Construction

[0021] refer to figure 1 , a laminated board, comprising a laminated support plate or cover plate layer 1, a high elastic buffer material layer 2, a common elastic buffer material layer or a high temperature resistant barrier material layer 3, a steel plate layer 4, and a product layer 5 to be laminated. The structure of the product layer 5 to be pressed is copper foil layer 51-adhesive sheet layer 52-copper foil layer 51, and both sides of the product layer 5 to be pressed are provided with steel plate layers 4, and the laminated board The layer 5 of the product to be laminated is composed of one or more layers and the steel plate layer 4 repeatedly at intervals. .The combined mode of the reinforced elastic buffer material can be followed by ordinary elastic buffer material layer or high temperature resistant barrier material layer 3, high elastic buffer material layer 2, ordinary elastic buffer material layer or high temperature resistant barrier material layer combination 3...

Abstract

The invention provides a hot-press elasticity-enhanced buffering material composition comprising at least one layer of a high-elasticity buffering material with an energy-storage modulus of 1-1000Mpa within a specific temperature range. The specific temperature range is 0-70 DEG C, 70-150 DEG C, 150-250 DEG C or 250-400 DEG C. The elasticity-enhanced buffering material also comprises a common-elasticity buffering material or a high-temperature-resistant barrier material. According to the hot-press elasticity-enhanced buffering material composition, with excellent resilience of the high-elasticity buffering material in the composition in a lamination process after lamination stress deformation, a substrate cavity defect with the use of a single common-elasticity buffering material such as kraft paper in a laminated plate lamination process can be effectively ameliorated or eliminated, and laminated plate product quality can be improved.

Description

technical field [0001] The invention relates to the technical field of laminated boards, in particular to a combination of reinforced elastic buffer materials for hot pressing and a laminate containing the combination of reinforced elastic buffer materials for hot pressing. Background technique [0002] At present, in the manufacturing process of laminates, thermosetting or thermoplastic resins and reinforcing materials are first made into impregnating materials (adhesive sheets) by wet or dry methods, and then the impregnating materials (adhesive sheets) are combined with copper foil, heated, pressurized, melted and flowed. Cured into one piece to make a laminate. [0003] During the lamination heating and pressing process, if there are defects such as uneven thickness, deformation, uneven temperature, hard foreign matter and other structural parts such as the lamination hot plate, rigid support plate and cover plate, the impregnating material cannot be applied during the l...
