Problems solved by technology

[0003] However, the existing problems in the current engineering application are: the adhesion problem of the combined use of waterproof coiled materials and waterproof coatings needs to be further resolved
If the bonding force is too strong, it is difficult for the waterproof layer to adapt to the adverse effects of the deformation of the base layer; if the bonding force is too weak, the coating and the coiled material are easy to separate. There is almost no peeling area in the layer, and the tensile stress cannot be transmitted to both sides but can only be concentrated in the cracked part. A small crack may cause the waterproof layer to be pulled; Accelerated aging due to high stress state, or fatigue failure due to repeated stretching

preparation example Construction

[0032] The preparation method of following high heat-resistant non-cured asphalt waterproof coating mainly comprises as follows:

[0033] (1) Add asphalt and softened oil, and raise the temperature to 130°C to 190°C, stir to dissolve completely;

[0034] (2) Add rubber powder, control the temperature at 130°C-190°C, and stir evenly (for example, stir for 40-90 minutes).

[0035] (3) Add oxidized polyethylene wax to the system in step (2), control the temperature to 130°C-170°C, and stir evenly (for example, stir for 70-95 minutes).

[0036] (4) Add fillers in batches to the system in step (3), control the temperature at 130°C-170°C, and stir evenly (for example, stir for 120-150 minutes).

[0037] (5) Cool down to 130°C to 160°C, and then discharge and pack.

Embodiment 1

[0039] Add 170 parts of asphalt, 50 parts of softening oil, 18 parts of polysulfide rubber, 8 parts of rubber powder, 4 parts of oxidized polyethylene wax (copolymer of polyethylene), and 80 parts of filler (talcum powder) in order, start the colloid mill, Mix and stir at 130°C-190°C for 3-6 hours until the system is uniform, and the material is discharged to obtain a high heat-resistant non-curing asphalt waterproof coating. Its performance index detection is shown in the following table:

[0040] Table 1. Test results of non-cured asphalt waterproof coating with high heat resistance

[0041]

[0042]

Embodiment 2

[0044] 220 parts of asphalt, 40 parts of softening oil, 15 parts of polysulfide rubber, 15 parts of rubber powder, 12 parts of oxidized polyethylene wax (graft polymer of polyethylene and vinyl acetate), 10 parts of rosin resin, 12 parts of plasticizer , 120 parts of filler (heavy calcium powder), 8 parts of defoamer are added in order, start the colloid mill, mix and stir at 130 ° C ~ 170 ° C for 4 ~ 8 hours, until the system is uniform, and the material is discharged, that is, high heat resistant Non-curing bituminous waterproof coating. Its performance index detection is shown in the following table:

Abstract

The invention relates to a high-heat-resistance non-cured asphalt waterproof coating and a preparation method thereof and belongs to the technical field of waterproof coating. The high-heat-resistance non-cured asphalt waterproof coating mainly comprises: 150-220 parts of asphalt, 30-55 parts of softening oil, 0-20 parts of rubber, 0-12 parts of rosin resin, 0-15 parts of rubber powder, 0-14 parts of a plasticizer, 2-10 parts of oxidized polyethylene wax, 60-150 parts of a filler and 0-10 parts of a defoaming agent. The non-cured asphalt waterproof coating has the advantages that the heat-resistant temperature can reach 90 DEG C, the adhesive performance is good, the waterproof performance is excellent, the construction temperature range is wide, and cracks in the waterproof base can be automatically repaired. The coating can be used alone and can be also used in combination with asphalt rolled waterproof materials.

Description

technical field [0001] The invention relates to an asphalt waterproof coating, in particular to a high heat-resistant non-curing asphalt waterproof coating and a preparation method thereof, belonging to the technical field of waterproof coatings. Background technique [0002] Waterproof materials are an important line of defense to ensure that construction projects are protected from water corrosion. Commonly used waterproof materials include waterproof membranes and waterproof coatings. At present, the most widely used composite waterproof system of waterproof membrane and waterproof coating is to combine waterproof coating and membrane, so that the waterproof layer not only has the advantages of uniform thickness and stable quality of the membrane, but also has the advantages of good integrity of the waterproof layer of the coating film. It has been widely used in waterproofing projects, and has played a very good role in improving the quality of waterproofing projects. ...
