Low-Vicat high-tensile polycarbonate and polymethyl methacrylate composite board and preparation method thereof

Abstract

The invention relates to a low-Vicat high-tensile polycarbonate and polymethyl methacrylate composite board. The composite board comprises a base layer, composite layers, reinforcing ribs, a protective layer and a wear-resistant layer, the composite layers are arranged on the upper side and the lower side of the base layer correspondingly, and the base layer and the composite layers are connected in a hot melting mode. The reinforcing ribs are arranged between the base layer and the composite layers, and the reinforcing ribs are connected with the base layer and the composite layers in an embedded mode; the protective layer is arranged on the outer side of the composite layer, and the protective layer is connected with the composite layer in a hot melting mode. The wear-resistant layer is arranged on the outer side of the protective layer, and the wear-resistant layer is connected with the protective layer in a bonding mode. By improving the structure, the composite board has the advantages of being convenient to machine and durable, and therefore the problems and defects in the prior art are effectively solved and overcome.

Description

technical field [0001] The invention relates to the technical field of composite panels, and more particularly, to a low-dimensional high-stretch polycarbonate and polymethyl methacrylate composite panel and a preparation method thereof. Background technique [0002] Composite panels are often seen in daily life, mainly including metal composite panels, wood composite panels, color steel composite panels, etc. All types of composite panels have their application fields and advantages, among which plastic composite panels are durable and durable. It is favored for its aesthetic good properties. [0003] However, although the common plastic product composite board has good water resistance and aesthetics, its softening point is relatively high, resulting in relatively poor processing performance, and its tensile strength and impact strength are also insufficient, which limits its performance. applications in more fields. [0004] In view of this, research and improvement are...
