Problems solved by technology

Although the patent makes full use of the advantages of nano-carbonyl iron powder, it also shows that after nano-filling asphalt, the effect of nano-materials can still be well exerted, but problems such as smoke caused by molten asphalt in the preparation process still need to be resolved

Abstract

The invention discloses a preparation method for a copper nanorod-reinforced asphalt root blocking material applied to a planted roof. According to a technical scheme in the invention, the preparationmethod comprises the following steps: dissolving matrix asphalt with a cosolvent, and carrying out mechanical shearing and stirring to form a reaction matrix; then adding small-molecule monomers, a promoter and a root blocking agent, and carrying out continuous stirring; and adding modified copper nanorods, and performing polymerization and cross-linking of the small-molecule monomers under the action of an initiator so as to finally prepare the root blocking material. The preparation method of the invention realizes the integrated waterproofing and root-blocking construction of the planted roof, and has the advantages of simple process, low production and construction temperature, low production cost, low construction difficulty, friendliness to environment and capacity of effectively improving the tear resistance of the root blocking material.

Description

technical field [0001] The invention relates to the field of planting roofing materials, in particular to a method for preparing copper nanorod-reinforced asphalt planting roofing root-resistance materials. Background technique [0002] With the rapid popularization of planting roofing technology in my country, root puncture-resistant waterproof materials for planting roofs are very important and widely used. According to the relevant requirements of JGJ155-2007 "Planting Roof Engineering Technical Regulations", root puncture-resistant waterproof materials must have the ability to withstand plant root puncture, biological corrosion, and mold resistance in long-term wet conditions. At present, some waterproof materials on the market generally have many problems including product raw material formula, production process, supporting construction technology and so on. As one of the waterproof materials, asphalt and its products require high processing temperature in the product...
