Abstract
The present invention provides modified rooting-resisting and waterproof asphalt sealing paste which is characterized in that the sealing paste is a mixture prepared from the components by weight: 40 to 60 of bitumen, 10 to 20 of atactic polypropylene, 2 to 5 of polyethylene, 2 to 5 of polypropylene, 5 to 10 of engine oil, 20 to 30 of filling material and 1 to 2 of rooting-resisting agent. The present invention has the preparation method that bitumen is added into a stirring tank, and the atactic polypropylene, the polyethylene, the polypropylene and the filling material are gradually added in the state of stirring and are uniformly mixed and stirred; the temperature can be always controlled from 180 to 210DEG C; the rooting-resisting agent and lube oil are uniformly mixed and are added in the material for full stirring and uniformly mixing; the sealing paste is produced through discharging, weighing and packaging. The present invention has the advantages of good rooting-resisting performance, strong heat resistance, good low-temperature performance, strong corrosion resistance, low cost and convenient use. The present invention can be widely used for occasions needing sealing and water prevention and resisting plant root growth for roof gardens, building roofs, underground buildings, bitumen roads, underground conduit interfaces, dams, runway panel seams, etc.
Description
Technical field:
The present invention relates to waterproof technique, a kind of body of paste modified asphalt composite that is used for building waterproof and has the root resistance effect is provided especially.
Background technology:
Continuous expansion along with urban construction, improving constantly of people's living standard, the big city land price rises steadily, greenery area in people's living environment is more and more littler, schedule is laid out in the reasonable utilization of roof area gradually, as in the roof construction roof garden, green plantss such as plantation flowers and plants, vegetables, fruitlet wood, not only can beautify the environment but also can have a rest for the people roof, carry out recreation.But, what the structure garden at first ran on the top, house is exactly the waterproof problem on roof, the various asphalt waterproofing materials that run in the market, just waterproof does not have the root resistance effect, thereby the waterproof layer of buildings leaks with regard to being easy to be penetrated by the root of plant, make troubles for people's life, cause damage.Therefore, the applicant has submitted a patent application on August 26th, 2002 to Patent Office of the People's Republic of China, wherein discloses a kind of modifying asphalt anti-root water-proof coiled material, application number 02274909.8.In the building waterproof construction, the cornice of roofing, gutter, the following mouth of a river, parapet, smokestack, the pipeline of turnover roofing and the waterproofing node place of vault, it is not enough only using coiled material, also is badly in need of the water-tight that a kind of and the matching used root resistance waterproof sealing compound of anti-root water-proof coiled material are finished buildings jointly.
The technology contents of invention:
The object of the present invention is to provide a kind of favorable waterproof property that both had, have the root resistance waterproof sealing compound of root resistance effect again, its functional, easy construction.
The invention provides a kind of modified aseismatic and waterproof asphalt sealing paste, it is characterized in that sealing cream is the mixture of being made by the raw material of following parts by weight:
Pitch 40～60

Modified aseismatic and waterproof asphalt sealing paste provided by the invention, described root-resistant agent are selected from phenoxy group fatty acid ester, phenoxy carboxylic acid root-resistant agent.
Modified aseismatic and waterproof asphalt sealing paste of the present invention, used pitch can be the petroleum pitch of the various trades mark such as No. 90, No. 140 road bitumens, No. 100, No. 180, first-selected No. 140 road bitumens.
In the modified aseismatic and waterproof asphalt sealing paste of the present invention, used stopping composition can be talcum powder, wilkinite, cock soil or Calcium hydrogen carbonate, first-selected talcum powder.
The present invention also provides the preparation method of above-mentioned modified aseismatic and waterproof asphalt sealing paste, it is characterized in that technological process is as follows:
A adds stirred pot with pitch, adds Atactic Polypropelene, polyethylene, polypropylene, stopping composition mixing and stirring under whipped state successively, and temperature is controlled in 180～210 ℃ of scopes all the time;
B mixes root-resistant agent earlier with lubricating oil, add in the above-mentioned material fully to mix again;
The c blowing, weigh, be packaged into product.
Among the preparation method of modified aseismatic and waterproof asphalt sealing paste provided by the present invention, be controlled to be the opportunity of whipping process a after preceding a kind of mixing of materials stirs and add a kind of material in back again.
Among the preparation method of modified aseismatic and waterproof asphalt sealing paste of the present invention, among the whipping process b, when all materials add, and temperature-stable is in the time of 195 ± 5 ℃ in the stirred pot, and the mixing of materials stirring reaction finishes.
Among the preparation method of modified aseismatic and waterproof asphalt sealing paste of the present invention, for preventing product material sedimentation before the packing moulding, layering, among the process c, stirred pot does not still stop to stir when the packing of product.
Modified aseismatic and waterproof asphalt sealing paste of the present invention has following advantage:
1, the root resistance performance is good.Can stop roots of plants to penetrate waterproof layer long-term effectively, being specially adapted to roof of buildings, vault needs each node of water-tight, and dykes and dams, asphalt roads, runway Surface plate seam etc. should prevent that again the root of weeds trees from penetrating the occasion of waterproof layer by water-tight.
2, thermal stability height can be adjusted as required with method of the present invention, produces the sealing compound of 100～150 ℃ of different thermal stabilitys, to adapt to the service requirements under China south and the high temperature occasion.
3, low-temperature performance is good, can adjust as required with method of the present invention, produces the sealing compound of the different low-temperature tenderness between-10 ℃～-30 ℃, to be fit to the service requirements under sub-northeast and the low temperature condition.
4, resistance to chemical attack is strong, and sealing compound of the present invention is at 50% sulfuric acid or Ca (OH)
21 year surface of submergence is no abnormal in the solution, is applicable to the environment and the occasion of soda acid.
5, cost is low.The raw material sources of sealing compound of the present invention are extensive, do not need valuable, special and imported materials, and production technique are simple.
