Abstract

The invention relates to an environment-friendly smoke-suppression-type non-cured rubber-asphalt waterproof coating material and a preparation method thereof. An environment-friendly waterproof material with a smoke suppression effect is achieved through adding smoke suppressants of certain fractions based on a non-cured rubber-asphalt waterproof coating material. The waterproof coating material contains the ingredients in percentage by weight: 35-45% of modified asphalt, 25-35% of dispersant, 5-12% of tackifier, 0.5-1.5% of physical smoke suppressant, 3-5% of polymer smoke suppressant and 20-30% of heavy calcium carbonate. The waterproof coating material has good creep property and bond strength and is outstandingly characterized by having smoke suppression characteristic. According to the waterproof coating material, a large volume of harmful smoke generated during the high-temperature melting of the non-cured rubber-asphalt waterproof coating material can be effectively suppressed. The waterproof coating material disclosed by the invention has the characteristics of never curing, low-temperature resistance, no high-temperature flow, good waterproof performance, environmental friendliness, smoke suppression and the like, and can be extensively applied to waterproof projects of various building structures.

Description

technical field [0001] The invention relates to a waterproof coating, in particular to an environment-friendly and smoke-suppressing non-curing rubber asphalt waterproof coating and a preparation method thereof. technical background [0002] Non-curing rubber asphalt waterproof coating has the characteristics of low temperature resistance, high temperature non-dripping, never curing, excellent creep performance, etc., especially when dealing with defects such as building deformation joints and displacement joints, it has a good waterproof effect. Therefore, non-curing rubber asphalt waterproof coatings have been widely promoted and applied in the field of building waterproofing in recent years. However, the non-curing rubber asphalt waterproof coating needs to be melted at high temperature before construction. During the high-temperature melting process, the non-curing rubber asphalt waterproof coating will release a large amount of asphalt smoke as the temperature rises. T...
