Problems solved by technology
Undoubtedly, the tensile strength of this type of laminated board in the prior art is obviously not ideal because its reinforcing material is fiber or fiber bundle, not biaxial or multiaxial fabric; The sheets are bonded with an adhesive, which is not only troublesome in the process, but also relatively high in preparation costs, and this kind of bonding connection is seam bonding, and it is extremely easy to add gas phase or liquid phase substances such as acids and alkalis. Penetrating into the bonding seam, resulting in degumming and delamination, which directly affects the practical quality and service life of the laminated board

Description
technical field [0001] The invention relates to a production method of a continuous glass fiber cloth reinforced thermoplastic sheet laminate, belonging to the field of material technology. Background technique [0002] The continuous glass fiber cloth reinforced thermoplastic plastic sheet of the present invention is a kind of thermoplastic plastic as the base material, with continuous glass fiber cloth as the internal reinforcement material, impregnated with thermoplastic plastics (such as polypropylene, polypropylene and other plastics) through the glass fiber cloth. ) A reinforced plastic sheet made by rolling. The thickness of this reinforced plastic sheet is generally in the range of 0.5~1mm, and most of them are provided in rolls for practical application or subsequent reprocessing. The production method of the continuous glass fiber cloth reinforced thermoplastic plastic sheet of the present invention was applied for a Chinese patent on the same filing date as the p...
