Background technique
Insulating layer in use, is easy to appear cracking phenomena in building trade, and national sector standard is required at it
On must there is anticracking grout or decorative mortar to carry out matching protection, need layer-by-layer gradual change, flexible release to resist on building heat preservation
Cracking, has also been formed insulating layer, just must matcoveredn or crack-resistant layer.In order to effectively prevent gypsum base thermal insulation mortar from opening
It splits, and efficiently uses industrial waste, specific aim has developed a kind of water-proof gypsum base anticracking grout.
Summary of the invention
Present invention aim to address above-mentioned deficiencies, provide a kind of water-proof gypsum base anticracking grout.
To achieve the above object, the present invention provides a kind of water-proof gypsum base anticracking grout, the parts by weight point of each component
It is not as follows:
The desulfurized gypsum, i.e. semi-hydrated gypsum, be steam power plant wet desulphurization after waste residue after drying and calcining process
The by-product of generation, main component CaSO41/2H2O, mesh number are 80-120 mesh.
The miberal powder is S95 slag powders, is fine powder of the waste residue of steel mill discharge after water quenching grinding.
The cement is general 42.5 cement of silicon.
The basic matterial is CaO, and mesh number is 325 mesh.
The cellulose ether is hydroxypropyl methyl cellulose ether (HPMC), and viscosity is 45000 or 75000MPa.S.
The water-reducing agent is melamine SM-1013.
The reinforcing material is wood fibre PWC500.
The river sand fineness is sand in 0.35-0.5mm.
The present invention also provides a kind of above-mentioned preparation methods of water-proof gypsum base anticracking grout, the specific steps of which are as follows:
A, by desulfurized gypsum, miberal powder, cement, basic matterial, cellulose ether, retarder, water-reducing agent, reinforcing material, can be again
Dispersed latex powder, river sand measure be stirred 2-3min according to the ratio；
B, it will be poured into after the water measured according to the ratio in stirring that step a is obtained material and 2-3min be mixed, obtain water-fast stone
Cream base anticracking grout.
For the present invention by reducing the cementitious material using rigidity, increasing a certain amount of has that cohesive force, flexibility be good, bonding
The strong additive redispersable latex powder of power, improves the flexibility of product, so that flexibility of the present invention is good；By adding strengthening material
Expect that wood fibre enhances cracking resistance, so that cracking resistance of the present invention is good；Desulfurized gypsum is rationally utilized, is carried out by rational proportion
Modified excitation, makes it become hydraulic material from air-setting material, solves resistance to water problems；Effective use consumption industrial waste
Material, energy conservation and environmental protection reduce cost.
