Abstract
A self-healing elastic waterproof paint and its preparation technology. The raw materials of the self-healing elastic waterproof paint are 20-40 wt% of rubber, 15-20 wt% of SBS, 1-2 wt% of zinc oxide, 20-50 wt% of asphalt and 2-10 wt% of polyisobutylene. The waterproof paint provided by the invention not only enhances the waterproofness and weather resistance of buildings, but also further raises the acid and alkali resistance of buildings, and simultaneously, it is convenient for construction; the waterproof paint can solve waterproof engineering difficulties such as the phenomenon of expending with heat and contracting with cold, the building seam displacement, corrosion resistance, fatigue resistance and the like, and its solid content reaches over 90% with no volatile matter being generated; it is never solidified, never melted at the high temperature of 130 DEG C, and never cracked at the temperature of minus 30 DEG C; when stabbing the paint with a knife, the knife edge heals so quickly that no drops of water can penetrate through the edge; the paint has good self-healing performance, corrosion resistance, fatigue resistance and good adhesion stress with a plurality of heterogeneous materials, it is widely used for the water proofing of subways, bridges, houses, pools and the like, and suitable for the thermal spraying construction, spreading construction, slip-casting leak stopping construction and wet-ground construction as well.
Description
Technical field
The invention belongs to waterproof paint and fabricating technology field thereof, be specifically related to a kind of self-healing elastic water proofing paint and the preparation technology thereof that can form waterproof layer.
Background technology
Waterproof paint is conventional buildings waterproof construction material, but cement concrete building ubiquity seepage defect, for addressing these problems, though existing market has multiple waterproof paint, though have the advantages such as inexpensive, anti-leakage ability is poor, and construction is complicated, environmental pollution is very large, is difficult to extensively promote the use of.Especially expand with heat and contract with cold, build the difficult point that seam displacement, erosion resistance, fatigue resistance etc. are waterproofing works always.
Self-healing elastic water proofing paint utilizes multiple auxiliary agent to react to form, in performance, be not only better than K11 waterproof paint, JS waterproof paint, polyurethane water-proof paint, and constructing operation is very simple, solid content reaches more than 90%, non-volatile thing, never solidify, lancination enters this coating and extracts, and the edge of a knife heals very soon, watertight, there is good self-healing property, erosion resistance, fatigue resistance, and the cohesive force good with multiple dissimilar materials.Construction of Thermal Spraying, knife-coat application and grouting for water plugging can construct, also can construct at wet ground.Be widely used in the waterproof such as subway, bridge dye, house.
Summary of the invention
The object of this invention is to provide a kind of is main waterproof composition with pitch, can knife-coat application, spraying application and grouting for water plugging construct, there is the waterproof paint of obvious high impermeability, solve building deformation joint, displacement seam, the defect of stitching of expanding with heat and contract with cold that on market, waterproof paint can not be tackled, and this coating never solidifies.
It take pitch as the preparation technology of the waterproof paint of major ingredient that another object of the present invention is to provide a kind of, the simple directly blade coating of preparation technology is in building surface, there is high temperature 130 DEG C do not trickle,-30 DEG C are not ftractureed, and solid content is more than or equal to 90%, watertightness 0.1Mpa, 30 minutes waterproof, cohesive strength is more than or equal to 0.3Mpa, and extensibility (non-processor) is more than or equal to 25mm, and resistance to strong acid, highly basic.
For achieving the above object, the technical scheme taked of the present invention is as follows:
A kind of self-healing elastic water proofing paint, is characterized in that the total weight percent that described waterproof paint raw material forms is
Rubber 20-40%
SBS 15-20％
Zinc oxide 1-2%
Pitch 20-50%
Polyisobutene 2-10%
Specifically, self-healing elastic water proofing paint and preparation technology thereof, is characterized in that described preparation technology is:
Rubber, SBS, zinc oxide, pitch are heated in a kettle. 100-190 DEG C, stir after one hour and add polyisobutene again, and stir and then load in the plastic tank of sealing for ten minutes, self-healing elastic water proofing paint can be obtained.
By the waterproof paint of pitch, rubber production, although have general water-proof function, impervious not ideal enough, especially can not tackle expanding with heat and contract with cold of building seam.But because SBS produces the main raw material of waterproof paint, after adding, not only water proof anti-seepage ability improves further, and self-healing property, extensibility strengthen further.Lancination enters this waterproof paint, then after extracting, the edge of a knife heals very soon, and the waterproof paint of a centimeter long can elongate 30 centimeters.
The invention has the beneficial effects as follows, this self-healing elastic water proofing paint is owing to adopting SBS, polyisobutene is main raw material, the waterproof making this waterproof paint not only have common waterproof paint to possess, moisture-proof function is outer and improve the weatherproof ability of buildings, high temperature 130 DEG C does not trickle,-30 DEG C are not ftractureed, self-healing property strengthens, construction technology is simpler, can knife-coat application, spraying application and the stifled construction of slip casting, its composition and construction meet the environmental requirement of national defined, this self-healing elastic water proofing paint apparatus and process is simple, be convenient to scale operation, product can be widely used in subway, tunnel, the waterproofing works such as building.
