Problems solved by technology

The non-curing rubber asphalt waterproof coatings currently on the market still have the disadvantage of poor heat resistance, and they often have to be heated above 180°C during construction to be thin enough (viscosity ≤ 1500mPa·s) to facilitate construction, and this type of modified asphalt coatings Usually more than 140 ℃ will produce obvious smoke, which limits its application range. Therefore, it is necessary to develop a high heat-resistant smokeless non-curing rubber asphalt waterproof coating to improve its application range.

Abstract

The invention discloses a high-heat-resistance smokeless non-curing rubber asphalt waterproof coating and a preparation method thereof. The non-cured rubber asphalt waterproof coating is prepared from the following raw materials in parts by weight: 50-60 parts of Kiel asphalt, 35-45 parts of spindle oil, 5-10 parts of butadiene styrene rubber, 5-10 parts of a styrene-ethylene-propylene-styrene block copolymer, 10-20 parts of water-white rosin pentaerythritol ester, 5-10 parts of a ZCR temperature control agent, 15-20 parts of a high-temperature modifier and 4-8 parts of a viscosity modifier. The prepared non-cured rubber asphalt waterproof coating is high in heat resistance, free of sliding, flowing and dripping at the temperature of 105 DEG C, free of smoke during construction, safe, environmentally friendly and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a high heat-resistant smokeless non-curing rubber asphalt waterproof coating and a preparation method thereof. Background technique [0002] Non-curing rubber asphalt waterproof coating is a one-component waterproof coating made of rubber powder, asphalt, polymer and other materials through special modifiers, additives, etc. A new type of waterproof material with creep properties that maintains a viscous paste for a long time in the application state. The coating can close the cracks and capillary pores of the base layer, and can adapt to complex construction work surfaces; it does not cure for a long time after contact with air, and always maintains the characteristics of viscous colloid. Bonding properties. It can solve the problems of waterproof layer rupture, flexural fatigue or premature aging under high stress state caused by the transmission of cracking stress from the ...
