Problems solved by technology

However, the bonding strength between the skeleton support layers between the foams is not enough to easily cause cracking problems, and the uniformity of heat insulation of the sandwich layer cannot be guaranteed, resulting in gaps between the foams, which have no impact on the mechanical properties and light transmission properties. It will lead to the reduction of the comprehensive performance of the composite board

Abstract

The invention belongs to the technical field of preparation of composite boards, and discloses an efficient heat insulation board and a preparation method thereof. The efficient heat insulation board comprises a first panel layer, a second panel layer and a sandwich layer, wherein the sandwich layer is formed by stacking one or more foam layers, and each foam layer is formed by splicing a plurality of foam blocks; the sandwich layer is located between the first panel layer and the second panel layer, and functional structure layers are arranged between the lower surface of the sandwich layer and the first panel layer, between the upper surface of the sandwich layer and the second panel layer, on the peripheral edge of the sandwich layer and in splicing seams of any two adjacent foam blocks in the sandwich layer; the first panel layer and the second panel layer are both made of a fiber reinforced resin composite material; the foam blocks are polyurethane foam blocks, PVC foam blocks or phenolic foam blocks; and the functional structure layers are composed of aerogel and functional filler. The efficient heat insulation board is provided with the functional structure layers with heat insulation, buffering and mechanical properties, and the overall comprehensive performance advantage of the composite board is further improved.

Description

technical field [0001] The invention belongs to the technical field of composite board preparation, and in particular relates to a high-efficiency heat insulation board and a preparation method thereof. Background technique [0002] The performance of light weight and thermal insulation has always been an important functional attribute in the application of panels, and it is also a hot research direction in the field of panels. Especially in the field of building materials, panels with light weight and excellent thermal insulation performance are very popular. This is because this panel has a low density, which greatly reduces the load-bearing burden of the building skeleton, and reduces the difficulty of construction, and the thermal insulation performance can also meet the application requirements. . [0003] At present, this kind of lightweight thermal insulation composite board is mostly composed of heat-insulating sandwich layers and panels, and the panels are mostly m...
