Embodiment 1

[0015]

[0016] Preparation method: Heat petroleum asphalt to 140°C, then add softener, modifier and flame retardant, stir evenly, continue to heat up to 160°C, develop at this temperature for 30 minutes, start the colloid mill to accelerate the swelling process, and make the modified The homogenization of the active agent is more complete. After 1 hour, add the anti-aging agent, stop the colloid mill, stir at a constant speed for 2 hours, add the filler, continue to develop for 45 minutes, and the product is produced after discharge.

[0017] The performance parameters of the flame-retardant non-curing rubber asphalt waterproof coating in this example are as follows: solid content 99.9%, heat resistance at 70°C without running, sliding, and dripping, low-temperature flexibility below -30°C, and extensibility at -5°C 30mm , Dry base surface and wet base surface adhesion are 100% cohesive failure, qualified self-healing, thermal aging, chemical corrosion basically no change a...

[0019]

[0020] Preparation method: Heat petroleum asphalt to 160°C, then add softener, modifier and flame retardant, stir evenly, continue to heat up to 180°C, develop at this temperature for 40 minutes, start the colloid mill to accelerate the swelling process, and make the modified The homogenization of the agent is more complete. After 1.5 hours, add the anti-aging agent, stop the colloid mill, stir at a constant speed for 1.5 hours, add the filler, continue to develop for 80 minutes, and the product is produced after discharge.

[0021] The performance parameters of the flame-retardant non-curing rubber asphalt waterproof coating in this example are as follows: solid content 99.9%, heat resistance 75°C without running, sliding, dripping, low temperature flexibility below -30°C, extensibility at -5°C 30mm 100% cohesive failure of dry base surface and wet base surface, qualified self-healing property, basically no change after heat aging and chemical corrosion for 160 hou...

[0023]

[0024] Preparation method: Heat petroleum asphalt to 160°C, then add softener, modifier and flame retardant, stir evenly, continue to heat up to 180°C, develop at this temperature for 50 minutes, start the colloid mill to accelerate the swelling process, and make the modified The homogenization of the active agent is more complete. After 1.5 hours, add the anti-aging agent, stop the colloid mill, stir at a constant speed for 2 hours, add the filler, continue to develop for 80 minutes, and the product is produced after discharge.

[0025] The performance parameters of the flame-retardant non-curing rubber asphalt waterproof coating in this example are as follows: solid content 99.9%, heat resistance 85°C without running, sliding, dripping, low temperature flexibility below -30°C, extensibility 30mm at -5°C , Dry base surface and wet base surface adhesion are 100% cohesive failure, qualified self-healing, no change after heat aging, chemical corrosion 200h, flame reta...

Abstract

The invention relates to a non-cured rubber asphalt waterproofing coating with flame retardance property. The non-cured rubber asphalt waterproofing coating is prepared from the following raw materials in parts by weight: 35-55 parts of petroleum asphalt, 5-25 parts of softener, 2-8% of flame retardant, 0.1-3 parts of antiaging agent, 5-20 parts of filling agent, and 0.1-2 parts of modifier. The non-cured rubber asphalt waterproofing coating disclosed by the invention has flame retardance property, the flame-retardant problem of a hot-melt waterproofing material can be effectively solved, the non-cured rubber asphalt waterproofing coating is convenient to construct, reliable to adhere, and self-healing, the non-cured rubber asphalt waterproofing coating and a self-adhesion modified asphalt waterproofing sheet material are composed to form a waterproofing system, and the water leakage and channeling problems caused by cracking of a waterproof layer due to deformation of a base layer can be effectively solved.

Description

technical field [0001] The invention relates to a self-healing non-curing waterproof coating, in particular to a non-curing rubber asphalt waterproof coating with flame-retardant properties, which belongs to the fields of building waterproof materials and civil construction engineering waterproofing. Background technique [0002] In recent years, non-curing rubber asphalt waterproof coatings have been greatly applied and promoted in the field of building waterproofing. However, although the non-curing asphalt coatings currently on the market have good waterproof effects, they do not have flame retardancy, which limits Its scope of application increases the risk of hot-melt construction and increases the risk of fire in buildings. Contents of the invention [0003] Aiming at the needs of the existing technology and the market, the invention invented a non-curing rubber asphalt waterproof coating with flame-retardant properties, which has both waterproof and flame-retardant ...
