1% composition, second group is divided into polyisocyanates component 100%, and the ratio of the first component and the second component is 100:100 ~ 200.
Preferably, the cellular board with spraying polyurethane combine material by a decorative layer, a surface layer, a honeycomb core,
One bottom is combined into one and forms a glass fabric paper honeycomb core reinforcing plate, and surface layer is located above bottom, honeycomb core
Above bottom, decorative layer is unlikely to deform for decorating cellular board, surface layer, bottom for promoting cellular board intensity.
Preferably, the decor surface uses spiral lamination structure.
Preferably, first component and the second component uniformly mix.
The present invention also provides a kind of cellular boards, and the preparation application method expected is combined with spraying polyurethane, which is characterized in that
It is the following steps are included: the first component is prepared according to the following steps: polyether polyol, crosslinking agent or the chain extension in the first component
Agent, catalyst, inner pattern releasing agent applicable, mill base and water sequentially add in stirred tank according to formula rate, stir 2 ~ 4 hours, and stirring is abundant
Inspection by sampling after uniformly, after the assay was approved barrelling；Second component be directly adopt commercially available PM200 or M20S or 44V20 or
The isocyanate products such as 5005 and similar thick MDI, the first component and the second component are uniformly mixed.
The positive effect of the present invention is that: the present invention can reduce the volatilization of VOC, improve fastness, structure letter
It is single, it is at low cost.
Detailed description of the invention
Fig. 1 is the schematic diagram of the invention in glass fabric honeycomb core reinforcing plate.
Specific embodiment
Present pre-ferred embodiments are provided with reference to the accompanying drawing, in order to explain the technical scheme of the invention in detail.
As shown in Figure 1, cellular board of the present invention with spraying polyurethane combine material 3 include the first component and the second component, first
Component is by polyalcohol 60 ~ 90%, crosslinking agent/chain extender 5 ~ 20%, catalyst 0.5 ~ 2.5%, inner pattern releasing agent applicable 0 ~ 5%, 0 ~ 5% He of mill base
Water 0.1 ~ 1% forms, and second group is divided into polyisocyanates component 100%, the ratio of the first component and the second component for 100:100 ~
200, it is therefore preferable to which 100:120 ~ 180, optimal is 100:160 ~ 180.
Cellular board combines material 3 for the 4, bottoms of honeycomb core of surface layer 2, one of decorative layer 1, one with spraying polyurethane
5 are combined into one and form a glass fabric honeycomb core reinforcing plate, and surface layer 2 is located at 5 top of bottom, and honeycomb core 4 is located at bottom
5 top of layer, decorative layer 1 are unlikely to deform, honeycomb core 4 for decorating cellular board, surface layer 2, bottom 5 for promoting cellular board intensity
Light weight, for reducing overall weight.
Cellular board of the present invention combines the preparation method of material the following steps are included: the first component presses following step with spraying polyurethane
Rapid preparation: in the first component polyether polyol, crosslinking agent or chain extender, catalyst, inner pattern releasing agent applicable, mill base and water is according to matching
Square ratio sequentially adds in stirred tank, stirs 2 ~ 4 hours, stirs full and uniform rear inspection by sampling, after the assay was approved barrelling；Second
Component is to directly adopt commercially available ten thousand Hua Huaxue of PM200() or M20S(BASF) or 44V20(Cohan wound) or 5005(Hensel
It is graceful) and the isocyanate products such as similar thick MDI, the first component and the second component are uniformly mixed by mixing apparatus.
Cellular board combines material with spraying polyurethane and is equably sprayed on generation processing cellular board two sides, by being molded, solidifying, bee
Nest plate is combined with spraying polyurethane expects for decorative layer, surface layer, cellular board, bottom to be combined into one and forms a glass fabric
