Abstract
The invention provides a creep type hot-melt rubber asphalt waterproof coating which has high solid content (more than 99 percent), good high-temperature resistance, excellent low-temperature flexibility and better creep property. The waterproof coating can be independently used as a waterproof coating layer, can also be compounded with a high polymer (SBS or APP) modified asphalt waterproof coiled material to form two waterproof layer protections, and similar products adopt a thermoplastic elastomer (such as star-shaped SBS) and a rubber powder modifier to modify asphalt. The invention adopts a brand-new polyolefin elastomer modifier and plastic modifier composite system, and compared with the existing non-cured asphalt coating, the product has better creep property and higher bonding strength, and better meets the requirements of facade construction.
Description
Technical field
The present invention relates to a kind of asphaltic base waterproof paint, be mainly used in various waterproofing works, waterproof construction separately, also can with the compound construction of waterproof roll.
Technical background
Domestic modifying asphalt coating mainly is solvent-borne type and water-latex type modified waterproof asphalt material; In use, the defective of various degrees is particularly used in the kitchen and toilet of improper ventilation and buildings; The one, the cycle of prolongation construction operation, the 2nd, the operating personnel is caused healthy effect.In order to change this situation, develop creep type hot melt rubber asphalt waterproof coating, this coating solid content high (more than 99%), high thermal resistance is good, and low temperature flexibility is excellent, and has better creep properties.
Creep type hot melt rubber asphalt waterproof coating can be used as film waterproof material separately; Also can with the compound use of superpolymer (SBS or APP) modified asphalt waterproof coiled material; Constituting two road waterproof layers sets up defences; Promptly be coated with rete together with coiled material layer, use at the tackiness agent (the quite sticking mastic of heat) of this dope layer double as coiled material.
The non-curing bituminous composition that existing market is, solid content high (more than 99%), creep properties is strong, but big area apply, can be used as packing matcrial, advantage such as easy to use, but it exist shortcoming be intensity too low, when facade is constructed, trickle easily.
The key distinction of creep type hot melt rubber asphalt waterproof coating and general modified waterproof asphalt material is that its good creep properties gives compound system self-healing ability and reply base course crack ability, has significantly reduced the engineering maintenance cost.Creep type hot melt rubber asphalt waterproof coating both can be used for newly-built waterproof layer, also can be used for repairing impaired waterproof layer; Both can be used for conventional regional waterproof, and also can be used for the waterproof of Special Areass such as movement joint, with respect to other water-proof material, it has unique advantage to the waterproof of Special Areas.The key element that the waterproof main body produces infiltration is water, slit and the migration force that passes through the water in slit, and waterproofing work is exactly to take the hole and the seam of fine and close clogged with material waterproof main body, stops passing through of water.Therefore from project angle, should at first seal the crack and the capillary channel of basic unit, make basic unit have certain waterproof ability; And then the tack coat with creep function is set, can be with main water barrier and basic unit's secure bond, and have good creep ability and eliminate or reduce the tensile stress of various unfavorable factors to the waterproof layer generation, avoid the waterproof layer tensile failure; Main water barrier with watertightness and weather resistance is set above that again; Add effective protection at last, promptly form complete water proof structure level.Being provided with like this can farthest reduce the influence of unfavorable factor to waterproof layer, improves the safety and the working life of waterproof layer greatly.And the tack coat of creep properties has stronger self-healing function, in case promptly certain position of waterproof layer is punctured destruction, its waterproof failure zone only is confined to damaged position and can not spreads; Simultaneously, the rheological of creep properties material can impel the part creep properties material of periphery gradually to this position migration, fills up damaged position, makes it have water-proof function again.
Summary of the invention
The object of the invention will provide a kind of creep type hot melt rubber asphalt waterproof coating exactly, this coating solid content high (more than 99%), and high thermal resistance is good, and low temperature flexibility is excellent, and has better creep properties.Can be separately as film waterproof material usefulness, also can with the compound use of superpolymer (SBS or APP) modified asphalt waterproof coiled material, constitute two road waterproof layers and set up defences, similar product all adopts thermoplastic elastomer (like star shaped SBS) and rubber powder modified agent that pitch is carried out modification.The present invention adopts brand-new polyolefin elastomer properties-correcting agent and plastic modifier compound system; This product is than existing non-curing bituminous composition; Have better creep properties, cohesive strength is higher, better adapts to the facade construction requirement, than CN201010293450.6 patented product better creep properties is arranged.
