Abstract
The invention discloses a hydrophobic roof sloping material and a construction method thereof and belongs to the technical field of construction materials. The material comprises cement, lightweight aggregate, waterproof gel and water, which are dispensed in a certain proportion to prepare a sloping layer meeting construction requirements in a construction process. The material has the characteristics of low cost, high hydrophobicity, high durability, convenience for construction, no burning, low volume weight and the like, and is low in thermal conductivity coefficient and high in heat-preservation performance; when the material and the method are used for the sloping engineering of a heat-preservation roof, the thickness of a heat-preservation layer can be effectively reduced.
Description
Technical field
The invention belongs to building material technical field, particularly a kind of roofing hydrophobic is looked for slope material and constructional method thereof.
Background technology
The construction work flat roof deck is in order to reach the purpose of getting rid of rain water on roof; often adopt and look for the method on slope to cause the slope of roof, on the horizental roof plate, lay one deck as light materials such as slag (cinder), haydite, cinder concrete, gas concrete particle, haydite concretes as sloping layer.Above several routine is looked for the slope material, the working procedure complexity, and construction technology is relatively backward; The materials procurement difficulties such as haydite; The volume water absorption rate is large, the mass defects such as infiltration, channeling water easily occur; Unit weight is large, has increased the load of roofing; Thermal conductivity is large, and heat-insulating property is poor.
The present invention adopts cement, light skeletal, waterproof gel and water to prepare to have that hydrophobicity performance is excellent, high insulating effect, operating efficiency is high, unit weight is little, do not burn, hydrophobic that the life-span is long is looked for the slope material.Can be used for new building roof slope making engineering, also can be used for the roof slope making of reconstruction of existing building engineering.
Summary of the invention
The object of the present invention is to provide a kind of roofing hydrophobic to look for slope material and constructional method thereof.Solve tradition and looked for the problems such as the working procedure existed in slope material and construction process is complicated, materials procurement is difficult, the volume water absorption rate is large, unit weight is large, heat-insulating property is poor.
A kind of roofing hydrophobic looks for the slope material to comprise: cement, light skeletal, waterproof gel and water, its proportioning is: 1:1.5～3:0.01～0.02:1.5～2.5.Wherein cement is a kind of in ordinary Portland cement, silicate cement, aluminosulfate cement, ferro-aluminate cement or magnesia oxychloride cement, the limited ordinary Portland cement of selecting.Light skeletal is pearlstone, expanded and vitrified small ball, haydite and floats in pearl one or more.The composition of waterproof gel and proportioning are vegetables oil: 15～20wt%; Stearic acid: 4～8wt%; Basic cpd: 5～12wt%; Trimeric cyanamide: 8～11wt%; Tai-Ace S 150: 3～6wt%; Water glass: 5～10wt%; Polyvinyl alcohol: 5～8wt%; Tributyl phosphate: 0.5～2wt%; Water: 36～40wt%.
The construction of for a kind of roofing hydrophobic, looking for the slope material, its concrete steps are: at first by cement, light skeletal, waterproof gel and water, the ratio according to 1:1.5～3:0.01～0.02:1.5～2.5 mixes and paves on roofing, step on or roll and will look for the slope material compaction by pin, require final thickness and the gradient must meet design requirements.
The invention has the advantages that:
1, the present invention adopts cement, light skeletal, waterproof gel and water to obtain through mix, have that cost is low, hydrophobic nature good, good endurance, do not burn, the outstanding advantages such as unit weight is low.
2, thermal conductivity of the present invention is low, good heat insulating, for have heat insulation house surface look for the slope engineering time, can effectively save the thickness of thermal insulation layer.
3, the present invention is directed to the roofing hydrophobic and look for the quick construction of slope material simple, by cement, light skeletal, waterproof gel and water through mix, pave, compacting gets final product.
