Abstract
The thick water-proof coating is prepared with petroleum asphalt, chlorosulfonated polyethylene, phenolic resin, hydrogenated castor oil, filler, compound solvent and some additive through heating and stirring, and features high solid content, less times of brushing and low pollution.
Description
The present invention relates to the architectural waterproof material technical field.It exactly is a kind of thick-slurry type waterproof paint.
Existing widely used waterproof paint, distinguish with regard to formulation, solvent-borne type and water-latex type two big class (response type such as urethane and epoxy resin class coating are arranged, because of too expensive, limited its widespread use), solvent-borne type and water-emulsifying type waterproof coatings, the shortcoming that a maximum is all arranged are exactly solid content not high (general about 40～50%), and once brushing film forming is thin, and (0.3～0.4mm) will just can reach required thickness through repeatedly brushing.Thereby influenced construction speed widely, increased difficulty.
Purpose of the present invention is exactly the shortcoming at above-mentioned waterproof paint, provides a kind of solid content height, brushing number of times few (once brushing can reach 0.8～1mm thick), pollutes for a short time simultaneously, uses solvent few, volatilizable film forming solvent-borne type thick-slurry type waterproof paint.
The present invention realizes above-mentioned purpose like this, with petroleum pitch (60# first or second) is base-material, chlorosulfonated polyethylene is material modified, resol is binding agent, hydrogenated castor oil is a thixotropic agent, process white, talcum powder are stopping composition, and dimethylbenzene, butanols are double solvents, also are aided with stablizer (tribasic toxilic acid aluminium, triethylene tetramine) and form.
Embodiment is as follows for prescription of the present invention (weight %):
Petroleum pitch (60#) 30
Chlorosulfonated polyethylene 12
Resol 0.5
Hydrogenated castor oil 1.5
Tribasic toxilic acid aluminium 4.5
Triethylene tetramine 0.5
Process white 25
Talcum powder 10
Dimethylbenzene 15.7
Butanols 0.3
Technological process of the present invention is:
1, petroleum pitch is added reactor and be heated to 200～220 ℃ of dehydrations, cool to 120～110 ℃.
2, add dimethylbenzene, butanols solvent, stir.
3, add chlorosulfonated polyethylene, stirring and dissolving (110 ℃ of temperature).
4, add hydrogenated castor oil, phenolic resin, tribasic toxilic acid aluminium, triethylene tetramine, stirring and dissolving (110 ℃ of temperature).
5, add process white, talcum powder stirs, the discharging packing.
Thick-slurry type waterproof paint physicals of the present invention is as follows by national standard " roofing waterproof paint quality index and test method " test:
| Index name | Index | Test result |
| Thermotolerance | 80±2℃5h | No change |
| Alkali resistance | The calcium hydroxide saturated solution soaks (15d) | Qualified |
| Cohesiveness | MPa≥0.2 | Qualified |
| Watertightness | Power hydraulic pressure 0.1MPa30min | Qualified |
| Low temperature flexibility | -10 ℃ of φ mm rods around | Flawless |
| Anti-fragility | Basic crack 〉=0.2mm | Do not ftracture 0.4mm film |
| Surface drying | ≤4h | Qualified |
| Do solid work | ≤24h | Qualified |
| Solid content | ≥45% | 80％ |
Test proof thick-slurry type waterproof paint quality of the present invention is closed the symbol national standard, and solid content is up to 80%, and speed of application is fast, suitable especially blade coating, and through using for many years, effect is fine.
