Spraying rapid-hardening rubber asphalt water-proofing material for pitched roof

Abstract

The invention provides a spraying rapid-hardening rubber asphalt water-proofing material for a pitched roof. According to the spraying rapid-hardening rubber asphalt water-proofing material, emulsified asphalt and high-molecular polymer rubber latex are prepared into liquid rubber asphalt emulsion component in the ratio by the latest technology, and then the liquid rubber asphalt emulsion component is mixed with a coagulating agent in the ratio so as to obtain a water-based spraying material. By adopting the spraying rapid-hardening rubber asphalt water-proofing material, the problem due to the construction of the pitched roof can be effectively solved. According to the spraying rapid-hardening rubber asphalt water-proofing material for the pitched roof, a cold-constructing spraying mode is adopted, which is simple to operate and high in efficiency; and the water-proofing weak and detailed links at the parts in the pitched roof, such as through-wall pipes and water falling ports, can be conveniently and quickly treated. The spraying rapid-hardening rubber asphalt water-proofing material can be quickly sprayed and cured to generate a film, and the film can be generated within 30 seconds; and the formed water-proofing film has the characteristics of high breaking elongation (more than 1000%), high elastic recovery rate (more than 90%), high bonding strength (more than 0.5MPa), outstanding low-temperature resistance (out of breaking at -30 DEG C), outstanding ageing resistance and high acid and alkali resistance.

Description

technical field [0001] The invention relates to a waterproof paint, in particular to a spray-coated quick-setting rubber asphalt waterproof paint for sloping roofs. technical background [0002] Many sloping roofs are basically designed without a waterproof layer. Many people think that concrete and tiles can achieve a good waterproof effect. In addition, if the roof has a certain slope, the water will be drained in time without causing leakage. Facts have proved that this design idea is wrong. Because there are too many joints in the blocks, the integrity of the roof cannot be fully guaranteed during construction, and it is prone to leakage, especially during storms and typhoons. Moreover, the tiles will produce fine cracks under the sun and rain all year round, which will reduce or even lose the waterproof ability of the tiles themselves. Ordinary waterproof membranes are more difficult to construct on slopes, and the comprehensive waterproof performance of the membranes ...
