Occur conflicting or will be understood that the combination of this technical scheme is not present when can not realize, also not in the requires of the utility model
Protection domain within.
The utility model proposes a kind of cracking resistance wallboard.
Wall plastering refers to smear cement mortar, mixed mortar, lime mortar etc. on metope.Coat of plaster, which relies primarily on, plasters
The bonding force of mortar and metope and be adhered on metope.Generally, the change of indoor temperature and humidity is smaller than outdoor, so causing wall
The principal element that cracks in plaster occurs in the inner wall surface of plate is the anti-crack ability of finish coat layer 7.
Floated coat is generally divided into three layers, i.e. bottom (preliminary screed-coat), middle level (screed-coat) and surface layer (finishing coat).
Wherein, the effect of scratch coat is the surface of finish coat and wallboard body is firmly bonded and preliminary levelling；What middle level was plastered
Effect be further it is levelling, reduce due to scratch coat mortar cracking cause top-crack；Finish coat mainly plays decoration and made
With typically requiring the thinner thickness of surface layer.
Reference picture 1, the utility model proposes a kind of cracking resistance wallboard.The cracking resistance wallboard includes wallboard body 1 and coat of plaster
4, the wallboard body 1 has relative first surface 2 and second surface 3.The coat of plaster 4 includes scratch coat layer 5, middle level
