Description
Technical Field
The invention belongs to the field of waterproof material preparation, and particularly relates to a copper-plated glass fiber base asphalt root-puncture-resistant waterproof coiled material.
Background
The development of green planting roofs is one of effective ways for relieving the urban heat island effect and protecting the urban ecological environment, the green planting roof engineering is composed of planting, waterproofing, drainage, heat preservation and insulation and other comprehensive technologies, the roofing waterproofing technology is particularly important, and once leakage occurs, great economic loss can be caused. The root puncture-resistant waterproof material is a high-efficiency waterproof material which inhibits the root system from further growing to the waterproof layer and avoids destroying the waterproof layer, the plant root system in the planted roof system has extremely strong penetrability, and if the root puncture-resistant waterproof material is selected improperly, the root puncture-resistant waterproof material can be penetrated by plant roots to cause leakage of buildings.
The root penetration resistant waterproof coiled material of asphalt is one of waterproof materials with larger use amount at present, and the root penetration resistant performance of the waterproof coiled material of asphalt realizes the function of root resistance by adding a chemical root-resisting agent into the asphalt or using a copper foil base. The chemical root-resisting agent has the following problems: firstly, the addition amount of the chemical root-blocking agent is too large, which can cause the plant to develop badly and even die, and the chemical root-blocking agent cannot play a role in blocking roots when the addition amount is too small; secondly, the added chemical root-resisting agent is easily decomposed to cause the failure of the root-resisting agent when the asphalt coiled material is constructed at high temperature and is melted at a joint, so that the integral root-resisting performance of the coiled material is poor; and thirdly, the chemical root inhibitor has timeliness and fails as the chemical root inhibitor changes along with the prolonging of time.
At present, the root-blocking principle of the copper foil tire base asphalt root-puncture-resistant waterproof coiled material is that the plant root system meets metal copper ions and can change the growth direction, so that the plant root system is blocked from continuing to grow downwards, and the copper foil tire base asphalt root-puncture-resistant waterproof coiled material has the advantages of stability and good root-blocking effect. However, the copper foil asphalt waterproof coiled material is hard, not easy to bend, and low in tensile strength and tear strength, so that a tire body is easy to bulge and break when the coiled material is subjected to corner folding in the construction process, the female corner part is difficult to treat, and the tire body is easy to wrinkle when heated in the construction process, and a void at a rosin joint and a seam is easy to form. Meanwhile, the copper foil base has poor adhesion with asphalt, and is easy to peel and delaminate. In addition, copper belongs to noble metals, and the copper foil is used as a base, so that the use amount of copper metal is increased, and the cost is increased.
CN07032689 discloses a root puncture-resistant SBS modified asphalt waterproof coiled material, which comprises an SBS modified asphalt layer and a surface barrier layer; irregular bulges are arranged on the plastic fixing net of the surface barrier layer, fine sand and mineral aggregate barrier mixtures are filled among the bulges, the PE film covers the surfaces of the bulges, and the plastic fixing net is attached to the surface of the SBS modified asphalt layer. The surface soil thickness is not more than forty centimeters, and the surface soil has no load-bearing effect.
CN107933035 discloses a root penetration resistant waterproof roll of modified asphalt, comprising an upper surface isolation layer, an upper modified asphalt layer, a base layer, a lower modified asphalt layer and a lower surface isolation layer which are of five-layer structure, wherein the upper and lower modified asphalt layers are made of modified asphalt, the modified asphalt is 90# petroleum asphalt; no. 70 petroleum asphalt; engine oil; styrene butadiene rubber; phenolated lignin; polyvinyl alcohol; n-phenyl-3-aminopropyltrimethoxysilane; a chemical root-arresting agent; tributyl citrate, hydrogenated rosin pentaerythritol ester; sodium carboxymethyl cellulose and modified nano calcium carbonate.
