Problems solved by technology

[0007] The present invention aims at the problem that the conventional products in the prior art have insufficient initial viscosity, breaks away from the base layer and is not full of pavement during construction on wet ground. After research and development, a non-curing rubber asphalt waterproof coating for wet ground of the present invention is obtained. The non-curing rubber asphalt is waterproof The coating is a new type of environmentally friendly, high-solid hot-melt asphalt waterproof coating that can be applied on wet ground

Abstract

The invention provides non-cured rubber asphalt waterproof coating for wet floors and a preparation method thereof. The non-cured rubber asphalt waterproof coating comprises a component I and a component II, wherein the component I is prepared from high-grade asphalt, softening oil, aromatic oil, a modifying, a ductility enhancing agent, rubber powder, petroleum resin, a filler and an anti-aging agent; the component II is prepared from ethyl acetate, rosin resin, a titanate coupling agent and calcium oxide. On wet or water-stained construction floors, a layer of component II is paved first andthen the component I is paved after 2 minutes. The non-cured rubber asphalt waterproof coating is novel environment-friendly and high-solid content hot-melt asphalt waterproof coating which can be applied to the wet floors. The non-cured rubber asphalt waterproof coating can be safely constructed rapidly on the wet floors while the quality is guaranteed; the initial adhesiveness and the full paving effect are not worse than those during construction on dry floors; the construction period can be greatly shortened.

Description

technical field [0001] The invention relates to a non-curing rubber asphalt waterproof coating for wet ground and a preparation method thereof, belonging to the technical field of architectural waterproof coatings. Background technique [0002] Non-curable rubber modified asphalt coating for waterproofing is a waterproof coating made of rubber and asphalt as the main components and mixed with additives to maintain a viscous paste within the service life. The coating can close the cracks and capillary pores of the base layer, and can adapt to complex construction work surfaces; it will not solidify for a long time after contacting with air, and always maintain the characteristics of viscous colloid, with strong self-healing ability, sticky to the touch, and difficult to peel off. °C still has good bonding properties. It can solve the problems of waterproof layer fracture, flexural fatigue or premature aging under high stress state caused by the cracking stress of the base la...
