Abstract

The invention belongs to the technical field of waterproof coatings, and provides a non-cured rubber asphalt waterproof coating for facades. The non-cured rubber asphalt waterproof coating comprises 30-60 parts of asphalt, 0-30 parts of softening oil, 2-5 parts of SBS, 1-4 parts of SBR, 0.5-3 parts of a tackifier, 0.5-5 parts of an amorphous alpha-olefin copolymer, 2-8 parts of a non-curing modifier, 15-40 parts of a filler and 0.2-1 part of a heat stabilizer. A preparation method for the coating comprises the following steps: mixing the asphalt and the softening oil until a temperature reaches 135-145 DEG C, adding the amorphous alpha-olefin copolymer, the non-curing modifier, the SBS, the SBR and the tackifier, carrying out heating to 170-190 DEG C, performing swelling for 3-4 hours, allowing a treated mixture to pass through a colloid mill, adding the heat stabilizer and the filler, and carrying out discharging at 150-160 DEG C. With such a technical scheme, the non-cured rubber asphalt waterproof coating provided by the invention overcomes the problems that conventional non-cured rubber asphalt waterproof coatings are prone to sagging and difficult to thickening in the facade construction process and a waterproof coiled material slides and falls off when the non-cured rubber asphalt waterproof coatings are used in cooperation with the coiled material.

Description

technical field [0001] The invention belongs to the technical field of waterproof coatings, and relates to a non-cured rubber asphalt waterproof coating for facades and a preparation method thereof. Background technique [0002] Leakage in building structures has long been a difficult problem in the construction industry. Due to thermal expansion and contraction, vibration, displacement, settlement and other reasons, the waterproof layer of the building will often be separated, delaminated, aged, and cracked, which will cause the waterproof layer of the building to fail, and leakage and water channeling will occur. General waterproof materials can meet the conventional waterproof requirements, but the special parts in the building structure where the concrete is easily deformed, such as deformation joints, have higher requirements for the use of waterproof materials, which should have good impermeability, cohesiveness, flexibility and extensibility, Requirements for loss re...
