Abstract

The invention relates to a heat preservation wall slab for a rear wall of a greenhouse. The heat preservation wall slab adopts a 5-layer structure, wherein the middle layer is a center slab layer that is 5-10 mm in thickness; the two layers above and below the center slab layer are heat preservation layers that are 10-20 mm in thickness; and the two layers above and below the heat preservation layers are antiflaming layers that are 5-10 in thickness. The center slab layer is pressed at one time by using aluminum alloy, wood plastic, aluminum plastic and polyphenyl foam particles; each heat preservation layer is formed in such a manner that two plastic foam slabs are bound together by a binding material layer; and each antiflaming layer consists of magnesium chloride, magnesium oxide, expanded vermiculite, binding agent and emulsifier. The heat preservation wall slab for the rear wall of the greenhouse has the advantages that the manufacturing is simple, the wall is high in strength, the heat preservation effect is good, and the flame resistance is high.

Description

technical field [0001] The invention relates to the field of building plate composite materials, in particular to thermal insulation materials for the back wall of a greenhouse. Background technique [0002] At present, most of the back walls of greenhouses on the market only focus on the strength and do not solve the thermal insulation function, which causes the heat in the greenhouse to dissipate relatively quickly, requiring increased heating capacity, resulting in a waste of fuel resources. And even though some greenhouse building materials pay attention to its thermal insulation function, there are defects that they cannot be flame-retardant. Therefore, it is of great significance to manufacture building wall panels for greenhouses that are both heat-insulating and flame-retardant. Contents of the invention [0003] In view of the above-mentioned defects existing in the prior art, the object of the present invention is to provide a light-weight thermal insulation wal...
