Water-proof adhesive and using method thereof
(1) technical field
The invention belongs to the building construction technology field, particularly a kind of water-proof adhesive and using method thereof.
(2) background technology
In the building construction at present, high-molecular polythene third (washing) synthetic fibre, the application of polyvinyl chloride (PVC) waterproof roll seldom because these materials are when being directly used in roofing construction, the big foaming of moisture cannot be constructed, and this material also is subjected to the influence of uviolizing easily, therefore country forbids that also not designing these coiled materials is used for roofing, just adopts this type of material at the vault position, and utilizes cement to add the rubber powder sticking construction, and the constructional method different-effect also is not quite similar during owing to construct, and comes off easily.Waterproof mainly adopts the SBS modified asphalt waterproof coiled material on the roofing at present, but shortcomings such as not environmental protection, cost height, bonding force are poor, roofing can not be gone up people's activity, the life-span is short that this material exists, and in relatively moister environment, the SBS material is also peeled off the generation hollowing easily.Therefore research and develop that a kind of to solve the bad water-proof adhesive of existing water-proof material adhesive property in wet environment imperative.In addition, under the situation of advocating the environmental protection and energy saving product energetically, if this product can be further used for high-molecular polythene third (washing) synthetic fibre of environmental protection, the bonding of polyvinyl chloride (PVC) waterproof roll then has more the market adaptability.
(3) summary of the invention
The object of the present invention is to provide a kind of water-proof adhesive that cohesiveness is good in wet environment and using method thereof.
The technical solution used in the present invention is as follows:
Water-proof adhesive, comprise lining, described lining is mixed by the raw material of following weight percentage: white cement 10-40%, mica powder 5-20%, grey calcium powder 5-20%, wollastonite powder 5-15%, quartz sand 10-40%, dispersibility rubber powder 0.1-0.7%, organosilicon powder 0.1-0.5%, xylogen 0.1-0.5%, polypropylene fibre 0.1-0.4%; Described quartz sand is the 20-80 order.
Further, in order to reduce the use cost of binding agent, described binding agent also comprises bed material, and described bed material is mixed by the raw material of following weight percentage:
White cement 10-40%, grey calcium powder 5-20%, wollastonite powder 5-20%, sepiolite powder 10-40%, coarse whiting 10-40%, polyvinyl alcohol powder 0.1-1%, xylogen 0.1-0.6%.
In the binding agent raw material of the present invention, white cement plays cohesive action, and that mica powder has is heat insulation, the effect of antiultraviolet, and wear resistance is good; The ash calcium powder can increase agglutinating intensity, toughness; Wollastonite powder is in order to gain in strength; Silicone content is not less than 98% in the quartz sand, and intensity height, wear resisting property are good; The dispersibility rubber powder is used for bonding, and organosilicon powder has favorable waterproof property; The xylogen good water-retaining property, insulation plays cohesive action simultaneously; The polypropylene fibre pulling force is good, can increase toughness; Not heat conduction of sepiolite powder in the bed material, insulation; Pva powder bonds.Form as can be known from it, no matter be lining or bed material, described binding agent water resistance is good, therefore can be applicable to the bonding of the bigger waterproof roll of wet environment and water content; Its uvioresistant and excellent heat insulation property can be applied to the bonding of outdoor particularly roof waterproof coiled material; And good wear resistance can guarantee walking about of people on the roofing; Described binding agent is a white, uses elegant in appearance; Binding agent of the present invention in addition is an aqueous binders, can be applicable to multiple occasion.
Described lining and bed material all are that separately raw material uniform mixing is got final product.Bed material is not necessary.
Binding agent of the present invention can use preferred following mode according to general binding agent:
At first to state a bit, during use, can only use lining, the cost height of lining only, use cost height; After cooperating bed material to use, can reduce use cost and but realize same adhesive effect.
If only use lining, can carry out in such a way: described lining is added water to into pasty state, directly be applied in afterwards carry out on two faces of waterproof roll bonding, the waterproof roll that bonds again after perhaps directly being applied on the exposed face of substrate and waterproof roll respectively, the total smearing thickness of lining is 2-6mm.
If lining cooperates bed material to use: be applied on the exposed face of waterproof roll after lining and water is mixed into pasty state, bed material and water are mixed into carry out on another face that is applied in substrate or waterproof roll behind the pasty state bonding.
Further, the smearing thickness of lining is 2-4mm, and the smearing thickness of bed material is 1-2mm.
The volume ratio of lining and water is 2-4: 1.
The volume ratio of bed material and water is 2-4: 1.
The volume ratio of lining, bed material and water is preferably 3: 1.
Described waterproof roll is polyethylene polypropylene or polyester material or polyvinylchloride material.
Described binding agent is used for the construction of roof waterproof coiled material bonding.
With respect to prior art, the present invention has following beneficial effect:
Water-proof adhesive of the present invention, the water resistance height can be applied to wet environment, has filled the blank in present technique field; Heat insulation, uvioresistant and fastness to rubbing are good, and the waterproof roll usage period after the standard code bonding must not be less than 5 years, use the time limit of service of the roof waterproof coiled material of binding agent of the present invention to be not less than 10 years.
