The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments:
The present invention comprises as shown in Figure 1: outer field pulp layer 1, outer field pulp layer 1 comprise that the raw material of following weight portion adds the water mixed pulp through proportioning and forms:
100 parts of high-early-strength sulphate aluminium cement or ferrous aluminate cements;
0~35 part in flyash;
0~10 part of building glue;
0.1~0.2 part frother.
Landfill has plastic-coated fiberglass gridding cloth 2 in the pulp layer 1, and pulp layer 1 inside is coated with foam layer 4, has through hole in the foam layer 4, is perfused with column slurry body 3 in the through hole.Column slurry body 3 connects upper surface and pulp layer soffit, and playing increases anti-folding, resistance to compression effect.The two ends up and down of column slurry body 3 shown in Figure 3 have groove, and anti-pressure ability is stronger.
Building glue can be for building 107 or 801 glue.Frother can be the rosin blowing agent.
Foam layer 4 is the highly foamed polystyrene plastic foamboard.Perhaps added in high-early-strength sulphate aluminium cement or ferrous aluminate cement, flyash, for building 107 or 801 glue at 10~30: 1 by volume by foam grain, water mixes and makes.
Among Fig. 2, the embodiment shown in Figure 3, the both sides of plate body of the present invention have tenon 6 and tongue-and-groove 5 respectively, so that install and use.
Below in conjunction with embodiment in detail preparation method of the present invention is described in detail:
Embodiment 1 (foam layer 4 is whole highly foamed polystyrene foam flitch):
Present embodiment 1 is by the raw material proportioning of following weight portion be made (most preferred embodiment):
