Problems solved by technology

The problems of chemical root inhibitors are as follows: 1. If the amount of chemical root inhibitors is too large, it will cause stunted growth or even death of plants; When the joints are hot-melted, it is easy to cause the added chemical root inhibitor to decompose and lead to the failure of the root inhibitor, which makes the overall root resistance of the coil worse; 3. The chemical root inhibitor is time-sensitive. The agent changes and becomes invalid
However, the copper foil asphalt waterproof membrane is relatively hard, not easy to bend, and has low tensile and tear strength. Therefore, the carcass is easy to bulge and break when the membrane encounters a corner during construction, and it is difficult to handle the inner corner. During the construction process, the carcass is easy to wrinkle when heated, and it is easy to form false welds and voids at the seams
At the same time, the copper foil base has poor adhesion to asphalt, and is prone to peeling and delamination
In addition, copper is a precious metal, and the use of copper foil as a base increases the amount of copper used and increases the cost.

Abstract

The invention discloses a copper-coated glass fiber base asphalt root puncture-resistant waterproof coiled material. The glass fiber is placed in a degreasing liquid for degreasing and neutralization; it is sensitized in a sensitizing liquid; it is activated in an activating liquid; and copper plating is adjusted with ammonia water. The pH value of the liquid is placed in the copper plating solution for copper plating; the asphalt impregnated material is prepared with No. 60 petroleum asphalt, and the SBS modified asphalt coating material is prepared with No. 180 asphalt, SBS, naphthenic oil and talcum powder; copper-coated glass fiber cloth or The copper-coated glass fiber mat prepared from copper-coated glass fiber bundles is used as the base of the coil and unfolded on the coil production line, fully soaked with asphalt impregnated material, covered with SBS modified asphalt coating material, and coated with polyethylene film isolation material on the surface , after cooling and staying, lowering the temperature, and packing into rolls, a copper-coated glass fiber base asphalt root-resistant waterproof membrane is obtained. The invention has high tensile and tear strength, good root puncture resistance and waterproof effect; adopts surface copper plating method, greatly reduces the usage of precious metal copper, and saves production cost.

Description

technical field [0001] The invention belongs to the field of waterproof material preparation, and in particular relates to a root-puncture-resistant asphalt-coated copper-coated glass fiber waterproof coiled material. Background technique [0002] The development of green planted roofs is one of the effective ways to alleviate the "urban heat island" effect and protect the urban ecological environment. The green planted roof project consists of multiple comprehensive technologies such as planting, waterproofing, drainage, thermal insulation, etc., among which roof waterproofing technology is particularly important. Once leakage occurs, it will cause great economic losses. Root puncture-resistant waterproof material refers to a kind of high-efficiency waterproof material that can inhibit the further growth of roots to the waterproof layer and avoid damage to the waterproof layer. The plant roots in the planting roof system have strong penetrability. If the root puncture-resis...
