Butyl rubber waterproof membrane and preparation method thereof

Abstract

The invention provides a butyl rubber waterproof coiled material and a preparation method thereof. The components of the butyl rubber waterproof coiled material of the present invention are proportioned in parts by mass as follows: butyl rubber, 100 parts; SIS, 10 parts ; Carbon black, 20 parts; Light calcium, 40 parts; 201 phenol formaldehyde resin, 10 parts; Vaseline, 10 parts. The butyl rubber waterproof coiled material of the invention has superior performance, good tensile performance, good temperature resistance, long service life, convenient repair, recyclability and recycling; in addition, the product is simple to produce, easy to construct, and low in overall cost.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a butyl rubber waterproof coiled material. At the same time, the invention also relates to a preparation method of the butyl rubber waterproof coiled material. Background technique [0002] SBS waterproof membrane is impregnated and coated with asphalt made of styrene-butadiene-styrene thermoplastic elastomer as a modifier, and the upper surface is covered with polyethylene film, fine sand, mineral flakes (granules) or aluminum foil. A sheet-shaped waterproof membrane that can be curled made of insulating materials such as copper foil and copper foil. The existing SBS waterproof material has the disadvantages of temperature sensitivity, low tensile strength and elongation, and poor aging resistance, and blowtorches are required for construction, which has potential safety hazards. [0003] The polymer waterproof membrane is based on synthetic rubber, synthetic resin o...

Problems solved by technology

Adhesives are needed in the construction process, and most adhesives contain organic solvents, which pollute the environment

[0004] The current butyl rubber waterproofing membrane is fully glued in the construction process. Since the construction membrane is firmly pasted on the waterproof base layer by the adhesive, once the base layer cracks, the butyl rubber waterproofing membrane will not have any space to extend and will Leakage is caused; while using the empty paving method or strip sticking method, there is water under the waterproof layer and the leakage point cannot be judged, resulting in extremely difficult maintenance.
