Abstract

The invention discloses an antiflaming puncture-resisting water-proof sheet as well as a manufacturing method and an application thereof; the sheet consists of 75-90 parts of puncture-resisting water-proof sheet raw material, 10-20 parts of composite antiflaming master batch and 1-5 parts of other assistants. Puncture-resisting water-proof sheet raw material, composite antiflaming master batch and other assistants are metered and mixed evenly according to formula, and the extrusion calendaring formation method is used for manufacturing the antiflaming puncture-resisting water-proof sheet. The antiflaming puncture-resisting water-proof sheet of the invention features numerous excellent comprehensive economic and technical function indexes, such as excellent flame retardance, water resistance, leakage resistance, weather resistance, high tensile strength, low line body expansion, large friction coefficient, strong deformation adaptability, wide temperature adaptation range, convenient usage, long service life, easy construction, low manufacturing cost and the like. The invention can be used for water proofing work such as high speed railway, tunnel, culvert, underground large-scale engineering and the like.

Description

technical field [0001] The invention belongs to the technical field of preparation of building waterproof materials, and relates to a puncture-resistant waterproof sheet (ZLECB for short) with fire resistance and flame retardancy and a preparation method thereof. Background technique [0002] At present, with the extensive application of plastic materials for construction and ordinary civilian plastics, the requirements for the flame retardancy of plastic materials are getting higher and higher. In order to meet the needs of the development of the national economy, more and more plastics are required to meet certain requirements. The flame retardant level, and the current conventional method is to directly produce flame retardant materials, so that plastic products can obtain flame retardant properties. The inventor has been engaged in the research of building waterproof materials for many years. On September 5, 2006, he applied for an invention patent for puncture-resistant...
