Problems solved by technology

The second is chemical root resistance. During the production of waterproof membranes, a chemical root resistance agent [main components are (R)-2-(4-chloro-2-methylphenoxy) octyl propionate and di- 2-(4-Chloro-2-methyl-phenoxy)propionic acid-polyethylene glycol], so that the plant roots cannot access the waterproof membrane
The effect of chemical root resistance is more prominent, but there are also some unavoidable disadvantages
For example, heating during construction and high-temperature stirring during production will destroy root inhibitors; excessive or insufficient dosage of root inhibitors will have adverse effects
Therefore, the current root-puncture-resistant waterproofing membrane generally combines two kinds of root-blocking methods to ensure better waterproof and root-puncture-resistant effects. There is a waterproof project for planting in the area, which cannot meet the engineering application

Abstract

The invention provides a SBS modified asphalt root puncture resistant waterproof coiled material and a production method thereof, belonging to the technical field of waterproof coiled materials. Including upper surface isolation layer, SBS modified asphalt layer, middle base layer, SBS modified asphalt layer and lower surface isolation layer; SBS modified asphalt layer is made of the following raw materials in parts by weight: 90# petroleum asphalt 50‑60 10-20 parts of 10# petroleum asphalt, 20-30 parts of SBS rubber, 15-25 parts of fluorosilicone rubber, 2-4 parts of vulcanizing agent, 0.5-1 part of vulcanization accelerator, 5-10 parts of silane coupling agent, 5-8 parts of active tackifying resin, 0.8-1.2 parts of antioxidant, 20-30 parts of filler, 3-5 parts of chemical root inhibitor. The waterproof membrane has good resistance to plant root puncture and strong salt and alkali resistance, and is suitable for waterproof projects in saline-alkali areas that require planting.

Description

【Technical field】 [0001] The invention relates to the technical field of waterproof coiled material, in particular to a SBS modified asphalt root puncture resistant waterproof coiled material and a production method thereof. 【Background technique】 [0002] With the development of urbanization in our country, green land is gradually decreasing. In order to improve living conditions and living environment, roof gardens have become the first choice for developers and architects. However, roof gardens have high requirements for waterproof membranes, not only to be waterproof, but also to be able to resist the invasion of plant roots into the membranes for a long time. Because the traditional waterproof membrane and ordinary polymer waterproof materials do not have root-resistant properties, they are easily penetrated by plant root tips, causing damage to the waterproof layer and leakage of the building, which will directly lead to the failure of the "building planting and greeni...
