Problems solved by technology

[0003] However, although the non-curing asphalt coatings currently on the market have good waterproof effects, they do not have flame retardant properties, which limits their application range. Because the hot-melt construction temperature is high, it not only consumes energy, but also is prone to fire. Poor, at the same time high viscosity, not easy to construct, so it is necessary to provide a flame-retardant non-curing rubber asphalt waterproof coating with good fluidity under lower temperature conditions

Abstract

The invention belongs to the technical field of building waterproof materials, and particularly relates to a viscosity-reducing flame-retardant type non-cured rubber asphalt waterproof coating and a preparation method thereof. The waterproof coating is prepared from the raw materials in parts by weight: 30-60 parts of petroleum asphalt, 10-30 parts of a softener, 3-10 parts of a modifier SBS, 5-20parts of a tackifier, 5-20 parts of waste rubber powder, 5-25 parts of a filler, 3-10 parts of a flame retardant and 2-6 parts of a flowability-increasing agent. The waterproof coating provided by the invention has multiple characteristics such as water resistance, viscosity reduction, easy flowing, flame retardance and the like, the construction temperature and energy consumption are reduced, the non-cured rubber asphalt waterproof coating is prevented from fire in construction and application, and the safety of the non-cured rubber asphalt waterproof coating is enhanced. According to the preparation method provided by the invention, the dissolution difficulty of the modifier in the mixture is lowered, on one hand, the dissolution of the modifier is facilitated, and on the other hand, the preparation temperature of the non-cured rubber asphalt waterproof coating is lowered, and the energy is saved.

Description

technical field [0001] The invention belongs to the technical field of building waterproof materials, and in particular relates to a viscosity-reducing flame-retardant non-curing rubber asphalt waterproof coating and a preparation method thereof. Background technique [0002] Non-curing rubber asphalt waterproof coating is a creeping waterproof coating. It is not a water-based coating, nor is it a solvent-based or reactive coating, but a solvent-free, non-film-forming one-component creeping coating. It has good bonding ability with metal, non-metal and concrete substrates, and has dual functions of waterproof and metal anticorrosion. It is suitable for municipal engineering, subway tunnels, dams, pools, road bridges, roofs, toilets, undergrounds Waterproofing and grouting plugging of other parts. [0003] However, although the non-curing asphalt coatings currently on the market have good waterproof effects, they do not have flame retardant properties, which limits their app...
