Problems solved by technology

Among them, during the use of copper-based root inhibitors, due to the weak combination of metal and polymer interfaces, defects are easily formed, which affects the water resistance of the coil.
At the same time, the use of copper salt will affect the water resistance of the coil, making the durability of the coil not high
The organic group root medicine is also used in practice, but it is easy to degrade in sunlight, and it is difficult to maintain the effectiveness for many years

Embodiment 1

[0023] This embodiment provides a root puncture-resistant waterproof membrane for planting roofs, which includes a tire base, an asphalt layer and a root resistance layer sequentially arranged on the tire base; wherein, the root resistance layer includes a waterproof paint surface and a uniformly dispersed layer. The composite nano-copper in the waterproof paint surface includes nano-copper particles and an organic layer uniformly coated on the surface of the nano-copper particles, and the organic layer is a polyacrylate layer.

[0024] In parts by mass, the raw materials of the composite nano-copper include: 50 parts of deionized water, 0.8 parts of sodium bicarbonate, 0.6 parts of initiator, 1.5 parts of surfactant, 1.5 parts of nano-copper particles, 17 parts of methyl acrylate, 15 parts of n-butyl methacrylate and 8 parts of dimethylaminoethyl methacrylate.

[0025] In other embodiments, in parts by mass, the raw materials of the composite nano-copper can be "45-55 parts o...

Embodiment 2

[0033] The difference between this implementation and Example 1 is that the organic layer is polyacrylamide, and in parts by mass, the raw materials of the composite nano-copper include: 50 parts of deionized water, 0.7 parts of sodium bicarbonate, and 0.3 parts of initiator , 0.6 parts of surfactant, 2 parts of nano copper particles, and 29 parts of acrylamide.

[0034] In other embodiments, in parts by mass, the raw materials of the composite nano-copper can be "45-55 parts of deionized water, 0.5-1 part of sodium bicarbonate, 0.2-0.5 part of initiator, 0.4 part of surfactant -0.8 parts, 1-2 parts of nano copper particles, and 20-35 parts of acrylamide".

[0035] The preparation steps of the composite nano-copper include: uniformly mixing acrylamide and 1 / 2 of deionized water to obtain an acrylamide solution; mixing initiator, surfactant, nano-copper particles, sodium bicarbonate and remaining deionized water Put it into the reaction kettle, heat it to 50-60° C. while stirr...

Abstract

The invention provides a root puncture-resistant waterproof membrane for planting roofs, comprising a tire base, an asphalt layer and a root resistance layer sequentially arranged on the tire base; wherein, the root resistance layer includes a waterproof paint surface and is uniformly dispersed in The composite nano-copper in the waterproof paint surface includes nano-copper particles and an organic layer uniformly coated on the surface of the nano-copper particles, and the organic layer is a polyacrylamide layer or a polyacrylate layer. The root puncture-resistant waterproofing membrane for planting roofs has excellent waterproof and root puncture-resistant properties, and has excellent application prospects.

Description

technical field [0001] The invention relates to the technical field of waterproofing, in particular to a root puncture-resistant waterproofing membrane for planting roofs. Background technique [0002] The waterproof membrane is mainly used for building walls, roofs, tunnels, highways, landfills, etc. It is a flexible building material product that can be rolled into a roll to resist external rainwater and groundwater leakage. There is no leakage connection between the building and the building, which is the first barrier of the entire project waterproofing and plays a vital role in the entire project. In order to improve living conditions and living environment, roof gardens have become the first choice of developers and architects around the world. However, roof gardens have high requirements for waterproofing membranes, not only to be waterproof, but also to resist the intrusion of plant roots into the membranes for a long time.
