Embodiment Construction

[0014] In order to better understand the present invention, the embodiments of the present invention will be explained in detail below with reference to the accompanying drawings.

[0015] Such as figure 1 As shown, a phenolic resin composite sandwich panel includes a first plate body 1 and a second plate body 2. A sandwich layer 3 is provided between the first plate body 1 and the second plate body 2. The board body 1 and the second board body 2 are made of phenolic resin plates. The inner surfaces of the first board body 1 and the second board body 2 are subjected to sandblasting or rough grinding with a grinding wheel, and the inner surface is roughened to form a rough inner surface. The upper surface layer 4, the lower surface layer 5, and the two sides of the sandwich layer are respectively bonded to the rough inner surface layers of the first plate body and the second plate body through epoxy resin glue. Of course, the inner surfaces of the first plate and the second plate...

Abstract

The invention discloses a composite phenolic resin sandwich panel which comprises a first panel and a second panel, wherein a sandwich layer is arranged between the first panel and the second panel; the first panel and the second panel are made of phenolic resin panels; the inner surfaces of the first panel and the second panel are rough surfaces; two sides of the sandwich layer are respectively adhered to the rough surfaces of the first panel and the second panel through an epoxy resin adhesive. According to roughening treatment on the adhesion surface, the roughness of the adhesion surface is improved, the adhesion area between the adhesion surface and the sandwich layer is enlarged, the adhesion strength is improved, and by adoption of the phenolic resin, the composite phenolic resin sandwich panel is low in compressive strength, high in ageing resistance, light in weight and good in fireproof performance and is particularly suitable for occasions with high comprehensive requirements such as fire resistance.

Description

Technical field [0001] The invention relates to the technical field of plastic plates, in particular to a phenolic resin composite sandwich panel. Background technique [0002] Most of the plastic composite panels in the prior art use polyvinyl chloride, polystyrene and other materials as the outer layer. The composite panels made of these materials have the problem that the overall quality is relatively heavy and easy to deform after use. The bonding reliability between the connecting layers is poor, and it is easy to loosen and crack. At the same time, many plates have defects such as flammability, low compressive strength, and poor aging resistance, which are not suitable for use in occasions with high comprehensive performance requirements. Summary of the invention [0003] The purpose of the present invention is to provide a phenolic resin composite sandwich panel in order to solve the above-mentioned problems in the prior art; the present invention increases the roughness of...
