Metal core self-repairing root resisting waterproof coiled material and preparation method thereof

Abstract

The invention discloses a metal core self-repairing root resisting waterproof coiled material and a preparation method thereof. The metal core self-repairing root resisting waterproof coiled material comprises a metal core layer; the two sides of the metal core layer are each provided with a macromolecule layer; one side or two sides of each macromolecule layer away from the metal core layer is provided with or are each provided with a non-cured-rubber layer; and the outer surfaces of the non-cured-rubber layers are provided with anti-adhesion isolation layers. Each non-cured-rubber layer is composed of, by mass, 30-50 parts of matrix asphalt, 6-8 parts of naphthenic oil, 12-16 parts of SEPS rubber, 10-15 parts of polyisobutylene, 0.5-0.8 part of modification additives, 5-10 parts of tackifying resin, 0.1-0.5 part of a reaction active agent, 15-25 parts of nanometer calcium carbonate and 0.5-1.0 part of a chemical root resisting agent. The metal core self-repairing root resisting waterproof coiled material integrates sealed waterproofing performance and multiple root resisting, and has the characteristics of self-repairing, puncture resistance, sealing adhesion, ageing resistance and long service life; and meanwhile, the metal core self-repairing root resisting waterproof coiled material has the multiple root resisting function, has a multiple insurance effect on preventing plant root puncture and solves the problem that roots of a roof greening plant puncture a waterproof layer.

Description

technical field [0001] The invention relates to building waterproof materials, in particular to a metal core self-repairing root-blocking waterproof coiled material and a preparation method thereof. Background technique [0002] With the continuous advancement of the "sponge city" construction, the focus of urban construction is no longer "concrete forest", that is, it can "breathe" like a sponge. As one of the important means of realization, roof greening measures have ushered in unprecedented challenges and opportunities. . [0003] The first link in the construction of "sponge city" is the problem of "absorption". To make urban buildings have the functions of absorbing, storing and slowing down rainwater, green roof measures can be adopted. long-standing problem. [0004] Many planted roofs have roof leakage after about 2 to 3 years, and the shortest one has roof leakage in less than 1 year. Compared with general roofing projects, the frequency of water leakage on plant...

AI Technical Summary

Problems solved by technology

[0005] The reason is that traditional waterproof materials cannot meet the requirements of the roof green planting system, because these materials do not have root-resistance properties and are easily penetrated by plant root tips, resulting in the failure of the "roof green" system and bringing hidden dangers to building safety
