Preparation method of SBS (Styrene Butadiene Styrene) root-resistant waterproof coiled material

Abstract

The invention relates to the technical field of building waterproofing, in particular to a preparation method of an SBS (styrene-butadiene-styrene) root-resistant waterproof coiled material. The waterproof coiled material sequentially comprises an upper sealing film, an upper asphalt layer, an upper sealing layer, a base material, an upper weaving layer, an aluminum plate layer, a lower weaving layer, a lower sealing layer, a lower asphalt layer and a lower sealing film from top to bottom. The preparation method comprises the following steps of: preparing and sequentially forming raw materials of a waterproof layer, sequentially forming and welding a root-resistant layer, and combining the waterproof layer and the root-resistant layer. The production and preparation processes of the waterproof coiled material are refined and classified, the waterproof layer and the root-resistant layer are produced in different production lines at the same time and are integrated in the final combination forming line, and the final combination forming of the coiled material is divided into a gluing pre-connection part and a hot melting final curing part. According to the preparation method, gaps of all parts of the coiled material can be effectively eliminated, the waterproof performance and the root resistance are integrated, the whole preparation process is optimized, and the production efficiency of the coiled material is improved.

Description

technical field [0001] The invention relates to the technical field of building waterproofing, in particular to a preparation method of an SBS root puncture-resistant waterproofing coiled material. Background technique [0002] Most of the current buildings are made of reinforced concrete structure. During the use of the building, it will always be eroded by the external environment. In order to ensure the service life of the building, it is necessary to make the building resistant to external erosion. For reinforced concrete structures, the most important thing is to ensure their good waterproof performance, because if the water flow erodes into the material, it will cause corrosion of the steel bars, loss of strength, and eventually make the overall aging of the building difficult to use. [0003] Most of the current building waterproofing projects use waterproof coiled materials or color steel tiles to build methods, and waterproof coiled materials are more concealed and ...

Problems solved by technology

[0004] However, the current preparation method of root-penetration-resistant waterproof membrane is too simple, the strength of the root-penetration-resistant layer in the membrane is insufficient, the overall root-penetration resistance of the membrane is poor, and the types of plants that can be cultivated are limited.
