Problems solved by technology

[0003] 1. Due to the hot-melt barbecue, the surface of the coil is damaged to a certain extent, the structure of the coil is damaged, and the life of the coil itself is affected and the waterproof effect is reduced;
[0004] 2. Open flame construction has unsafe hidden dangers and is easy to cause fire;
[0005] 3. Toxic and harmful gases are produced during the construction process, which not only damages the health of workers, but also pollutes the environment
To solve this problem, the only way is to change the construction process of modified asphalt waterproofing membrane, and seek a construction process with no pollution and little pollution. The cold bonding method came into being. The cold bonding method is the direction and direction of future membrane construction. trend, but there is no suitable cold adhesive for waterproofing membranes

Embodiment 1

[0026] The steps during the preparation of a modified asphalt cold adhesive are as follows:

[0027] The first step is to add 15 parts by weight of naphthenic oil to 45 parts by weight of No. 100 asphalt and heat it to 140 ° C for 1 hour to dissolve;

[0028] The second step is to add 10 parts by weight of SIS1105 or SBS796 and 10 parts by weight of emulsifier OP-10 to the asphalt and heat up to 180 ° C for 1.5 hours to dissolve;

[0029] Step 3 Then add 10 parts by weight of styrene-butadiene rubber powder to the asphalt and keep the temperature at 180°C to dissolve for 1.5 hours;

[0030] Step 4 Cool the asphalt to 140°C, add 15 parts by weight of terpene resin, and discharge after fully dissolving.

Embodiment 2

[0032] The steps during the preparation of a modified asphalt cold adhesive are as follows:

[0033] The first step is to add 15 parts by weight of naphthenic oil to 45 parts by weight of No. 100 asphalt and heat it to 140 ° C for 1 hour to dissolve;

[0034] The second step is to add 10 parts by weight of SIS1105 or SBS796 and 10 parts by weight of emulsifier OP-10 to the asphalt and heat up to 180 ° C for 1.5 hours to dissolve;

[0035] Step 3 Then add 10 parts by weight of styrene-butadiene rubber powder to the asphalt and keep the temperature at 180°C to dissolve for 1.5 hours;

[0036] Step 4 Cool the asphalt to 140°C, add 15 parts by weight of hydrogenated rosin, and discharge after fully dissolving.

Embodiment 3

[0038] The steps during the preparation of a modified asphalt cold adhesive are as follows:

[0039] The first step is to add 15 parts by weight of aromatic oil to 45 parts by weight of No. 100 asphalt and heat it to 140 ° C for 1 hour to dissolve;

[0040] The second step is to add 10 parts by weight of SIS1105 or SBS796 and 10 parts by weight of emulsifier OP-10 to the asphalt and heat up to 180 ° C for 1.5 hours to dissolve;

[0041] Step 3 Then add 10 parts by weight of styrene-butadiene rubber powder to the asphalt and keep the temperature at 180°C to dissolve for 1.5 hours;

[0042] Step 4 Cool the asphalt to 140°C, add 15 parts by weight of C5 resin, and discharge after fully dissolving.

Abstract

The invention belongs to the technical field of cold adhering construction of waterproof coiled materials, and discloses a modified asphalt cold adhesive and a preparation process of the modified asphalt cold adhesive. The modified asphalt cold adhesive is mainly technically characterized by comprising No.100 asphalt, a thickening agent, an organic solvent, butadiene styrene rubber powder, a modifier, an emulsifier, etc.; the thickening agent is terpene resin, hydrogenated rosin, abietin or C5 resin; the organic solvent is naphthenic oil or aromatic oil; the modifier is SIS1105 or SBS796; and the emulsifier is OP-10. According to the modified asphalt cold adhesive, the high-quality solvent is adopted, nearly no harm and pollution are brought to the atmosphere and the environment, the problem that a polyethylene film is hardly adhered can be solved, and the construction is low; and when the modified asphalt cold adhesive is adopted and used for carrying out the construction to the waterproof coiled material through a cold adhering way, the process is simple in construction, and green and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of cold bonding construction of waterproof coiled materials, and in particular relates to a modified asphalt cold adhesive and a preparation process thereof. Background technique [0002] The modified asphalt waterproof membrane is tightly bonded between the membrane and the base surface to form an outsourcing waterproof layer around the entire building structure to achieve the waterproof effect. At present, the bonding between the modified asphalt coil and the base surface is mainly achieved by hot-melt method. The hot-melt method is to melt a layer of hot-melt polyethylene (PE) film on the surface of the modified asphalt waterproofing membrane and the modified asphalt rubber with an alcohol blowtorch or a spray gun, and then stick it on the surface coated with benzene and other solvents while it is hot. Base treatment agent on the base of the building. Although the hot-melt method is simple in process an...
