Layer.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is a part of the embodiment of the utility model, instead of all the embodiments.Based on the reality in the utility model
Apply example, those of ordinary skill in the art's every other embodiment obtained without making creative work, all
Belong to the range of the utility model protection.
The utility model is further described in detail with reference to the accompanying drawing:
As shown in Figure 1, according to a kind of multilayer polyurethane foaming hot-pressed board provided by the utility model, comprising: precoat
1, glue layer 2, keriotheca 4 and glass foaming layer 3；Keriotheca 4 is set between two layers of glass foaming layer 3, and precoat 1 passes through glue
Water layer 2 is adhered to 3 surface of a glass foaming layer；Glass foaming layer 3 includes layer glass fibrous layer 32 and three layers of polyurethane foam
Layer 31, layer glass fibrous layer 32 is staggered with three layers of polyurethane foaming layer 31.
In this embodiment, by the way that the glass layer 32 of two layers of low grammes per square metre to be substituted to the glass fibre of one layer of high grammes per square metre,
The number of plies of the glass layer 32 and polyurethane foaming layer 31 that make entire plate increases, and enhances while reducing material weight
The structural strength of plate, to improve the strength character of plate while cost is reduced.
In the above embodiment, it is preferable that glass foaming layer 3 is that polyurethane spray is applied to the keriotheca being placed in mold
4 and 32 two sides of glass layer, and permeate between keriotheca 4 and glass layer 32, the foaming of the interlayer of glass layer 32
Form polyurethane foaming layer 31.
Specifically, multilayer polyurethane foaming hot-pressed board is produced by semi-automatic production line, first draws keriotheca 4
Pre-set dimension is stretched and be cut to, glass layer 32 is cut into pre-set dimension, then by compound glass fibrous layer 32 and keriotheca 4
