Summary of the invention
The object of the invention is to provide a kind of environmental protection, intensity is large, rupture strength good, waterproof fireproofing and freeze proof light composite board.
The present invention realizes by following technological means: by adopting the light materials such as haydite, expanded perlite, prepare a kind of environmental protection, light composite board that combination property is strong with cement, quartz sand, flyash and other auxiliary agents according to certain proportioning.
Light composite board of the present invention, comprise precoat and be positioned at the middle sandwich of layers of two-layer precoat, between described precoat and sandwich of layers, be embedded with grid cloth, wherein, described precoat contains 20～30% cement, 50～70% quartz sand, 0～15% flyash, 1～6% water reducing agent, 0.5～1.5% silicone based waterproof agent and 0～0.1% thickener by weight percentage; Described sandwich of layers contains 30～45% cement, 40～55% haydite, 0～15% expanded perlite, 0.5～2% water reducing agent by weight percentage.
When the precoat of preparation light composite board of the present invention, water/binder ratio is 0.65～0.85; When preparation sandwich of layers, water/binder ratio is 0.45～0.60.
Preferably, in order to guarantee the steady quality of sheet material, in light composite board of the present invention, the granularity of quartz sand used is 40～600 orders.
Preferably, in light composite board of the present invention, water reducing agent used is naphthalene water reducer, particularly efficient naphthalene water reducer.
Preferably, in light composite board of the present invention, thickener used is the hydroxypropyl methylcellulose that hydroxypropyl methylcellulose (HPMC), particularly viscosity are 40000.
The light composite board of making according to formula of the present invention, quality is light, is convenient to install; Intensity is large, rupture strength good, can bear larger mechanical load, thereby building is played to reinforcement effect; In addition, also there is waterproof, fire prevention and anti-freezing property, in long-term use procedure, there will not be the phenomenon of leak, make moist mouldy and bursting by freezing, effectively extended the application life of sheet material, thereby saved use cost.Generally speaking, light composite board of the present invention has good combination property, under adverse circumstances, also can use for a long time, has broad application prospects.
