Problems solved by technology

At present, due to the limitations of equipment and molds at home and abroad, it is impossible to produce ultra-large and ultra-thick polymethyl methacrylate sheets.
The invention patent obtained by the applicant first: a polymethyl methacrylate bonding preparation method, which is the first time in China to disclose the processing of the side bonding surfaces of more than two polymethyl methacrylate sheets, taking into account the high overall strength , high shear strength, no influence on light transmittance, when the impact strength and elastic modulus are enhanced, the production of super-large planar size plates has been realized, but the technical problems of ultra-thick size plate production have not been overcome, neither at home nor abroad. There are related technologies that can realize the production of ultra-thick acrylic sheets

Abstract

The invention relates to a multi-layer one-time body composite manufacturing method of an acryl plate. The method comprises the following steps: feeding a plate into a forming mold to manufacture an acryl plate with a fixed plate thickness of L cm; preparing a composite material into composite material slurry; preparing a composite coating liquid to obtain the composite coating liquid; the coating thickness of the composite coating liquid being L / 10mm; performing multi-layer composite molding on the plate; mold making and preheating; performing composite pouring; carrying out nitrogen pressure maintaining during whole mold preparation; and carrying out high-temperature demolding. The method is simple in production process, and can effectively consider the properties of high shear strength, high light transmittance and the like of multi-layer compounding.

Description

Technical field [0001] The present invention relates to an acrylic sheet, particularly a method for manufacturing a composite acrylic sheet multilayer body once. Background technique [0002] PMMA is a thermoplastic material having excellent impact resistance, aging resistance, high light transmission properties, widely used in advertising signs, technology products, kitchen, electronic information, rail, aerospace, aquarium field. With the continuous expansion of its field of application, large size and thick PMMA sheet market demand. At present, due to the limitations outer equipment, a mold, and can not produce large-size thick polymethyl methacrylate plate. Applicants previously obtained a patent: preparation of methyl methacrylate adhesive polyethylene, in two or more first time discloses a polymethyl methacrylate plate bonding surface side is processed, taking into account the overall strength , high shear strength, light transmittance of no effect, enhanced impact strength...
