First base plate 3 and second base plate 4 are the cement layer of pouring on intermediate lamella 1, and anticracking layer 2 is the net cloth, and first default is greater than the second default, sets up first base plate 3 into the base plate that plays main supporting role to provide sufficient intensity for interior wallboard, so the thickness of second base plate 4 can be very little, and second base plate 4 can be very thin promptly, has reduced production cost. The grid cloth is arranged in the thin second substrate 4, so that the second substrate 4 cannot crack and has certain strength, and the quality of the whole inner wallboard is improved. The utility model provides a production process of interior wallboard can be as follows:

first, a layer of cement slurry in a molten state is laid in a mold.

Then, when the cement paste is not set, i.e., when the cement paste has a certain plasticity and fluidity, the first face of the intermediate sheet 1 is directed toward the mold, and the intermediate sheet 1 is brought into contact with the cement paste in the mold.

The second side of the intermediate plate 1 is then covered with an anti-splinter layer 2.

And finally, paving a layer of cement paste with the thickness of a second preset value on the second surface of the middle plate 1, and taking out the inner wallboard from the mould after the cement paste is completely solidified.

Further, the middle plate 1 is a heat insulation plate or a sound insulation plate. The heated board forms for insulation material die-casting, has the function that prevents the temperature diffusion in the wall with the wall outside for intermediate lamella 1 has heat retaining effect for the interior wallboard of heated board. Similarly, the middle plate 1 and the inner wall plate of the sound insulation plate have the sound insulation function. In actual production, can be according to the nimble material composition of adjusting intermediate lamella 1 of customer's needs to satisfy customer's demand, make the utility model provides an interior wallboard application scope is extensive.
