Low-temperature-resistant asphalt waterproof coating and method for preparing same

Abstract

The invention belongs to the technical field of building waterproof coating, and particularly relates to low-temperature-resistant asphalt waterproof coating. The low-temperature-resistant asphalt waterproof coating comprises, by weight, 70-80 parts of asphalt, 3-5 parts of modification auxiliaries, 10-16 parts of modified plant ash, 6-8 parts of amylopectin, 3-6 parts of sulfur powder, 6-8 parts of natural rubber powder, 1-3 parts of anti-aging agents, 2-4 parts of 2, 6-di-tert cresol, 3-5 parts of carbon black and 1-3 parts of talc powder. The invention further discloses a method for preparing the low-temperature-resistant asphalt waterproof coating. The low-temperature-resistant asphalt waterproof coating and the method have the advantages that the low-temperature-resistant asphalt waterproof coating prepared by the aid of the method is excellent in low-temperature crack resistance and is still excellent in needle penetration in low-temperature environments, excellent toughness can be kept, and accordingly the low-temperature-resistant asphalt waterproof coating and the method have excellent market prospects.

Description

[0001] 【Technical field】

[0002] The invention belongs to the technical field of architectural waterproof coatings, and in particular relates to a low-temperature-resistant asphalt waterproof coating and a preparation method thereof.

[0003] 【Background technique】

[0004] Waterproof coating refers to a coating formed by coatings that can prevent rainwater or groundwater from seeping. According to the coating state and form, waterproof coatings are divided into: emulsion type, solvent type, reactive type and modified asphalt. Emulsion-based and solvent-based waterproof coatings generally have relatively high costs and are not suitable for large-scale use. Therefore, most buildings in my country currently use asphalt waterproof coatings. However, most of the current asphalt waterproof coatings have poor weather resistance and are prone to aging, especially in low temperature environments, which are easy to harden, crack and leak, which affects the waterproof effect of buildin...
