Abstract

The invention belongs to the technical field of waterproof coatings, and provides a normal-temperature rapid-reaction non-cured rubber asphalt waterproof coating. The coating comprises a component A and a component B; the component A is composed of the following components: 2-10 parts of an isocyanate, 10-30 parts of polyether polyol, 1-5 parts of 3-(2,3-epoxypropoxy)propylmethyldiethoxysilane, 0.5-3 parts of boron nitride, 0.1-1 part of sorbitol, 20-40 parts of petroleum asphalt, 10-20 parts of tackifying resin, 10-20 parts of aromatic oil, 10-20 parts of a plasticizer and 1-5 parts of surfactant; and the component B is composed of the following components: 2-30 parts of amino-terminated polyether, 1-5 parts of an amino chain extender, 20-50 parts of petroleum asphalt, 20-50 parts of aromatic oil, 1-5 parts of a surfactant, 1.3-3.5 parts of polyethyleneimine, 0.1-0.5 part of a catalyst and 0.5-2 parts of nano kaolin. The mass ratio of the component A to the component B is (1-3):1 during application. During using, the component A and the component B are mixed, and then scraping coating or spraying coating construction is carried out by using the mixture. According to the technicalscheme, the problem that a non-cured rubber asphalt waterproof coating in the prior art has poor adhesion and low peeling strength to a substrate is solved.

Description

technical field [0001] The invention belongs to the technical field of waterproof coatings, and relates to a normal-temperature quick-response type non-curing rubber asphalt waterproof coating and an application thereof. Background technique [0002] Nowadays, there are more and more applications of composite waterproofing in waterproofing projects, especially the composite use of non-curing rubber asphalt waterproofing coatings and asphalt waterproofing membranes is becoming more and more prosperous. 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 sta...
