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 preparation technology thereof that can form waterproof layer.
Background technology
Waterproof paint is the buildings waterproof construction material of using always, but cement concrete building ubiquity seepage defect, for addressing these problems, though existing market has multiple waterproof paint, though have advantages such as inexpensive, the anti-leakage ability is relatively poor, and construction is complicated, environmental pollution is very big, is difficult to extensively promote the use of.Especially expand with heat and contract with cold, build seam displacement, erosion resistance, fatigue resistance etc. is the difficult point of waterproofing work always.
The self-healing elastic water proofing paint is to utilize multiple auxiliary agent reaction to form, not only on performance, be better than K11 waterproof paint, JS waterproof paint, polyurethane water-proof paint, and constructing operation is very simple, solid content reaches more than 90%, no volatile matter, never solidify, lancination advances this coating to be extracted again, and the very fast healing of the edge of a knife is watertight, have good self-healing property, erosion resistance, fatigue resistance, and the cohesive force good with multiple dissimilar materials.But Construction of Thermal Spraying, knife-coat application and grouting for water plugging construction also can be constructed at wet ground.Extensively apply to waterproof such as subway, bridge dye, house.
Summary of the invention
The purpose of this invention is to provide a kind of is main waterproof composition with pitch, but knife-coat application, spraying application and grouting for water plugging construction, waterproof paint with the impervious ability of tangible height, solved the defective that the building movement joint that waterproof paint can not be tackled on the market, displacement are stitched, expanded with heat and contract with cold and stitch, and this coating solidifies never.
It is the preparation technology of the waterproof paint of major ingredient with pitch that another object of the present invention provides a kind of, the simple directly blade coating of preparation technology is in building surface, having high temperature does not trickle for 130 ℃,-30 ℃ 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 anti-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 is formed 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:
With rubber, SBS, zinc oxide, pitch in reactor, heat 100-190 ℃, stir and to add polyisobutene again after one hour, and stir in the plastic tank of the sealing of packing into then in ten minutes, can obtain the self-healing elastic water proofing paint.
By the waterproof paint of pitch, rubber production, though 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 is a main raw material of producing waterproof paint, after the adding not only the water proof anti-seepage ability further improve, and self-healing property, extensibility further strengthen.Lancination advances this waterproof paint, after extracting again, and the very fast healing of the edge of a knife, one centimeter long waterproof paint can elongate 30 centimeters.
The invention has the beneficial effects as follows, this self-healing elastic water proofing paint is owing to adopt SBS, polyisobutene is a main raw material, the waterproof that makes this waterproof paint not only have common waterproof paint to be possessed, moisture-proof function is outer and improved the weatherproof ability of buildings, high temperature does not trickle for 130 ℃,-30 ℃ are not ftractureed, self-healing property strengthens, construction technology is simpler, but knife-coat application, the stifled construction of spraying application and 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, is convenient to scale operation, and product can be widely used in subway, the tunnel, waterproofing works such as building.
