Abstract

The invention discloses a butyl adhesive tape primer for a roof TPO waterproof roll, and application thereof. The application comprises the following steps: applying the primer to a construction matrix, and then adhering a butyl adhesive tape to the surface of the primer. Raw materials of the butyl rubber tape comprise a first butyl rubber matrix and an oxide, and the oxide is selected from one ora combination of more of manganese dioxide, zinc oxide, lead dioxide and lead tetroxide; the primer comprises, by weight: 8-25% of a second butyl rubber matrix, 1-15% of a second tackifying resin, 0.2-2% of a cross-linking agent, and 65-85% of an organic solvent; and the cross-linking agent is p-benzoquinone dioxime, The primer disclosed by the invention has a synergistic effect with conventionaloxide-containing butyl rubber after construction, so that the peel strength, persistent adhesion, water resistance and the like of the butyl rubber tape can be remarkably improved, and particularly,the problem that the performance of the butyl rubber tape is seriously reduced due to long-term soaking of concrete can be solved.

Description

technical field [0001] The invention belongs to the field of butyl rubber waterproof sealing adhesive tapes, in particular to butyl tapes for TPO waterproof coils, in particular to a butyl tape primer for roof TPO waterproof coils and an application thereof. Background technique [0002] Butyl rubber waterproof sealing adhesive tape has excellent air tightness, high temperature resistance and good adhesion at low temperature. It is suitable for lap joint sealing of polymer waterproof membranes such as TPO, and seams in color steel plate and sun board projects. Waterproof and airtight, sealing and waterproofing of subway tunnel structure construction joints, etc. [0003] The biggest disadvantage of butyl rubber is that it is easy to cold flow, that is, the cohesive strength is low, and a series of methods must be adopted in the production process to improve the cohesive strength, that is, the stickiness index. In addition, when used for concrete sealing and bonding, due to ...
