Problems solved by technology

[0004] However, most of the non-curing rubber asphalt waterproof coatings in the domestic market are as described in the above scheme, and their performance is uneven. Especially in long-term use, it is difficult to meet the secondary water seepage phenomenon caused by the further development of water seepage cracks in actual buildings. , especially in large-scale municipal infrastructure, the water seepage cracks that often appear in settlement joints, deformation joints, etc. are under great stress and develop extremely fast, which will tear the non-curing rubber asphalt waterproof coating filled in it, affecting the long-term use of buildings When the waterproof performance requirements

Abstract

The invention discloses a non-cured rubber asphalt waterproof coating. The non-cured rubber asphalt waterproof coating comprises, by weight the following components: 55-60 parts of modified asphalt, 5-10 parts of tackifying resin, 10-15 parts of rubber powder, 15-20 parts of liquid filler, 10-15 parts of powdery filler and 5-10 parts of metallocene type polypropylene. By adopting the composition,the added tackifying resin further improves the viscidity of the asphalt, meanwhile the powdery filler and the rubber powder can also improve the liquidity and creep properties of the asphalt, the added liquid filler and the added metallocene type polypropylene further improve the overall creep properties of the waterproof coating, the non-cured rubber asphalt waterproof coating can meet the waterproof demands of different cracks, the bonding performance and self-healing property are both improved, and an engineering application range is further widened.

Description

technical field [0001] The invention relates to the field of waterproof materials, in particular to a non-cured rubber asphalt waterproof coating and a preparation process thereof. Background technique [0002] Asphalt is a by-product of oil extraction, but it is widely used in various projects. It is a natural high-quality waterproof, moisture-proof and anti-corrosion organic gel material. The non-curing rubber asphalt waterproof coating is a waterproof coating that is made of rubber and asphalt as the main component and mixed with additives to maintain a viscous paste within the service life. It has more features than simple asphalt as a waterproof component. Good advantages have been gradually accepted and recognized by the market in recent years. [0003] The Chinese patent document whose application publication number is CN107142017A discloses a non-curing rubber asphalt waterproof coating, which includes asphalt, softening oil, synthetic rubber, resin, tackifying resi...
