Problems solved by technology

[0005] In order to solve the problem of durability and strength, vulcanized rubber and chemically cross-linked polymer coils are often used in the production process, because vulcanized or cross-linked polymers will lose weldability and reduce adhesion, often affecting the reliability of construction. Hidden dangers, especially the poor quality of welding and bonding joints, have also become the main cause of roof leakage

Abstract

The invention belongs to the field of research and development of high performance and high durability of universal materials in the field of novel materials, and particularly relates to an organic rear earth polymer ultraviolet crosslinked exposed waterproof roll and a preparation method thereof. According to the technical scheme, the organic rear earth polymer ultraviolet crosslinked exposed waterproof roll is prepared from the following materials: blended polymers, a compound lead salt stabilizer, a plasticizer, a softener, a filling pigment, an organic rare earth polymer, a crosslinking activator, an ultraviolet initiator and an initiating promoter. Molecular crosslinking is carried out by virtue of external natural ultraviolet rays in the field by using an ultraviolet and rare earth compound crosslinking system, so that the molecular conformation is changed and an ultraviolet-tolerant mechanism is formed so as to obtain a colored waterproof roll which can be exposed to use, and therefore the roll becomes a feasible technical case of high durability of the universal material.

Description

technical field [0001] The invention belongs to the field of high-performance and high-durability research and development of general-purpose materials in the field of new materials, and in particular relates to an organic rare-earth polymer ultraviolet crosslinking exposed waterproof coiled material and a preparation method. Background technique [0002] The rapid development of urban construction and the construction industry has brought about quality problems of buildings, among which the complaint of waterproof layer leakage has always been at the top of the list, so the problem of roof waterproofing of buildings has also received great attention and has become a key factor in the progress of construction technology. One of the keys. An effective way to solve the leakage problem from a technical point of view is to use polymer waterproof membranes to replace the previous asphalt-based membranes. Among them, the most notable comprehensive technical and economic characteri...
