Abstract

The invention belongs to the technical field of building materials, and provides a novel high-temperature-resistant non-curing waterproof coating. The coating is composed of the following components in percentage by weight: 25-35% of asphalt, 15-30% of rubber oil, 10-20% of waste tire rubber powder, 5-10% of styrene-butadiene rubber, 1-3% of styrene-butadiene-styrene (SBS), 4-10% of tackifying resin, 10-20% of fly ash, 2-5% of a high-temperature modifier and 2-5% of a viscosity reducer, wherein the high-temperature modifier is a BL modifier or polyamide wax. The preparation method is carried out by adopting a three-section-type feeding method and comprises the following steps: adding asphalt and rubber oil, carrying out heating to 150 DEG C, then adding the SBS, the styrene-butadiene rubber, the tackifying resin and the viscosity reducer, carrying out heating to 180 DEG C, then adding the fly ash and a high-temperature modifier, mixing the components at 180 DEG C to form a uniform liquid, and carrying out cooling and discharging to obtain the novel high-temperature-resistant non-curing waterproof coating. The invention solves the problem that a non-curing rubber asphalt waterproofcoating is poor in heat resistance.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a novel high-temperature-resistant non-curing waterproof coating and a preparation method thereof. Background technique [0002] Non-curing rubber asphalt waterproof coating is a hot-melt polymer rubber modified asphalt waterproof coating with high solid content. It has the characteristics of long-term non-curing, self-healing power, sticky when touched, difficult to peel off, and good low-temperature bonding performance. And other characteristics, can solve the problem that the traditional curing coating can not solve the waterproof layer cracking, fatigue damage or premature aging under high stress state caused by the stress change of the base layer transmitted to the waterproof layer. The composite waterproof layer is formed by the combined use of materials, which can solve the problem of water channeling which is difficult to be solved by using waterproof membrane al...
