High anti-impact waterproof and dampproof composite board

Abstract

The invention discloses a high anti-impact waterproof and dampproof composite board which is composited by multiple layers of materials. The high anti-impact waterproof and dampproof composite board comprises an upper structure, a lower structure and a honeycomb paperboard layer which is arranged between the upper structure and the lower structure, wherein the upper structure sequentially comprises an upper wear-resistant plastic film layer, an upper paperboard foaming layer, an upper waterproof film layer and an upper high anti-impact fiber layer from top to bottom; the lower structure sequentially comprises a lower wear-resistant plastic film layer, a lower paperboard foaming layer, a lower waterproof film layer and a lower high anti-impact fiber layer from bottom to top; the upper and lower paperboard foaming layers are panels by foaming paper fibers, polylactic acid, aliphatic polyester and a thermoplastic elastomer as main materials which are mixed. The composite board has excellent anti-impact and waterproof and dampproof properties, is simple in manufacturing process, easy to obtain raw materials and low in cost, can be widely applied in the field of high-grade packages, effectively reduces the thickness of the packaged products and improves the performance.

Description

technical field [0001] The invention relates to the field of composite cardboard, in particular to a high-impact, waterproof and moisture-proof composite board that has excellent impact resistance and is waterproof and moisture-proof. Background technique [0002] In the field of packaging boards, high requirements are put forward for the cushioning properties of the boards. It is necessary for the packaging boards to remain undamaged under strong impact. As the most widely used packaging material in recent years, honeycomb paperboard has good cushioning properties, but It is prone to deformation under long-term large static pressure. At the same time, with the improvement of packaging requirements, more and more products require the packaging to have certain waterproof and moisture-proof characteristics to protect the quality of the inner packaging. Ordinary honeycomb cardboard is difficult to meet. For example, patent CN102991076A discloses a waterproof and moisture-proo...

Problems solved by technology

Ordinary honeycomb paperboard is difficult to meet

For example, patent CN102991076A discloses a waterproof and moisture-proof carton board structure, which adopts a waterproof film, a polymer waterproof layer and a silica gel waterproof layer in the multi-layer cardboard to achieve the effect of waterproof and moisture-proof, but the impact resistance of the board itself is relatively low. Poor, prone to deformation, if the cardboard itself is damaged, it will undoubtedly have a great impact on its waterproof and moisture resistance

Patent CN104057678A discloses a high wear-resistant, waterproof and moisture-proof composite board and its preparation method and application, but it is mainly for the manufacture of composite wood boards, which are heavy and not suitable for light packaging
