Abstract

The invention discloses a butyl tape primer for roofing TPO waterproof coils and an application thereof. The application comprises: applying the primer to a construction substrate, and then adhering the butyl tape to the surface of the primer The raw material of butyl tape comprises the first butyl rubber matrix and oxide, and oxide is the combination of one or more selected from manganese dioxide, zinc oxide, lead dioxide and trilead tetroxide; In terms of content, the primer includes: 8-25% of the second butyl rubber matrix; 1-15% of the second tackifying resin; 0.2-2% of the cross-linking agent; 65-85% of the organic solvent; Benzoquinone dioxime; primer of the present invention works synergistically with conventional butyl rubber containing oxides after construction, can significantly improve the peel strength, stickiness and water resistance of butyl tape, especially can also solve the long-term problem of concrete The performance of butyl tape caused by water immersion is seriously degraded.

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 ...
