Problems solved by technology

Therefore, non-curing rubber asphalt waterproof coatings are widely used at present, but the traditional non-curing rubber asphalt waterproof coatings have low heat resistance, basically around 65-70 degrees, and the façade construction is easy to flow and slip under high temperature in summer. For this kind of heat resistance, the general stress relaxation is also above 0.25, and the creep property is not very good.

Abstract

The invention provides a heat-resistant non-cured rubber asphalt waterproof coating, a preparation method and a coiled material thereof. The heat-resistant non-cured rubber asphalt waterproof coatingcomprises the following components in parts by weight: 55-65 parts of asphalt, 1-5 parts of tackifying resin, 1-5 parts of SBS, 20-35 parts of a plasticizer, 1-5 parts of modified SBR, 10-17 parts ofdesulfurized rubber powder, 2-4 parts of a silane coupling agent and 0.2-0.5 part of a heat-resistant modifier. The product obtained by adopting the technical scheme of the invention is green and environment-friendly, not only can keep a never-cured form, but also has higher heat resistance and cohesiveness, the heat resistance can reach 100 DEG C, the thermal aging property is good, and long-termand reliable waterproof and heat-resistant functions can be exerted.

Description

technical field [0001] The invention belongs to the field of building engineering materials, and in particular relates to a heat-resistant non-curing rubber asphalt waterproof coating, a preparation method and a coiled material thereof. Background technique [0002] In building waterproofing engineering, the vibration of the building, thermal expansion and contraction, subsidence, deformation and cracking of the base will cause the waterproof layer to break and cause leakage. In practical engineering applications, for waterproof projects with large deformation of the base, the waterproof layer is generally constructed using the empty laying method or the point-bonding method to alleviate the damage to the waterproof layer caused by deformation and cracking of the base, but it is still prone to local leakage and Cause water leakage and so on. Therefore, there is an urgent need for a new type of creep material in the field of building waterproofing. The property can well abs...
