Abstract

The invention discloses a DTM polyester macromolecular composite waterproof coiled material which comprises a polyester layer I, a macromolecular layer I, a macromolecular layer II and a polyester layer II. All the physical mechanical properties are obviously higher than the national standard; the normal-temperature tensile breaking strength is not smaller than 91N / cm in the longitudinal direction and is not smaller than 96N / cm in the transverse direction; the normal-temperature elongation at break is not smaller than 616 percent in the longitudinal direction and is not smaller than 678 percent in the transverse direction; the tearing strength is not smaller than 70N in the longitudinal direction and is not smaller than 77N in the transverse direction; the combined strength is not smaller than 1.0N / mm in the longitudinal direction; furthermore, the DTM polyester macromolecular composite waterproof coiled material has performances such as aging resistance and corrosion resistance.

Description

technical field [0001] The invention relates to a DTM polyester polymer composite waterproof coiled material and a production method, belonging to the technical field of chemical product production. Background technique [0002] At present, waterproofing membranes occupy an important position in building materials, and the quality of waterproofing membranes directly affects the quality of the entire construction project. Ordinary waterproofing membranes are mainly petroleum, asphalt, paper tires and linoleum, which account for about 70% of the total market in the near future, polymer waterproofing membranes only account for about 10%, and the rest are waterproof coatings and other waterproofing membranes materials, but this type of material has its own shortcomings that are difficult to overcome. For example, a large amount of waste gas is produced during the preparation of asphalt, which seriously pollutes the environment, and is prone to burns and fire accidents. In part...
