Abstract

The invention discloses an anti-sagging modified asphalt waterproof coating. The waterproof coating is prepared from, by weight, 75 to 125 parts of a silicone acrylic emulsion, 200 to 300 parts of cationic emulsified asphalt, 65 to 75 parts of water, 260 to 350 parts of talcum powder, 1.8 to 2.2 parts of a defoaming agent, 4.5 to 5.5 parts of a dispersing agent, 2.6 to 3.4 parts of a thickening agent and 18 to 22 parts of anti-sagging auxiliary agent polyglycerol-3 diisostearate. The invention also discloses a preparation method of the anti-sagging modified asphalt waterproof coating. The modified asphalt waterproof coating prepared by the invention has the characteristics of high solid content, good stability, high drying speed, good anti-sagging performance, good high temperature resistance and good low temperature resistance.

Description

technical field [0001] The invention relates to the field of building waterproof materials, in particular to an anti-sag modified asphalt waterproof coating and a preparation method thereof. Background technique [0002] Traditional waterproof materials mainly include flexible waterproof materials such as waterproof membranes, waterproof coatings, and sealing ointments, as well as rigid waterproof materials that are based on cement substrates and add liquid medicine and other additives. Waterproof coating refers to a coating formed by coatings that can prevent rainwater or groundwater from seeping. Waterproof coatings can be divided into emulsion type, solvent type, reactive type and modified asphalt according to the state and form of the coating. [0003] In recent years, with the rapid development of my country's infrastructure construction, people's demand for waterproof coatings is increasing, and the performance requirements for waterproof coatings are also getting high...
