Problems solved by technology

However, with the rapid development of national public utilities in recent years, the time limit for many road construction projects is tight, so that public utility construction companies have to choose autumn and winter and rainy seasons when the weather conditions are disadvantageous for road construction. The low temperature in autumn and winter , dryness, and high humidity in the rainy season have brought many problems to the construction workers during the construction process. This seasonal construction operation is very inconvenient, which virtually increases the workload of the construction and greatly reduces the construction efficiency.
Therefore, the existing stress cloth can no longer meet the rapid development of construction engineering, and a new type of stress cloth is urgently needed to solve this problem

Embodiment 1

[0018] A self-adhesive stress cloth, including a base cloth and a waterproof layer, the base cloth adopts a warp-knitted directional structure, and the base cloth is made of alkali-free glass fiber yarn (purchased from Taian Glass Fiber Co., Ltd.) and polyester glass fiber cloth (purchased from Taian Fiberglass Co., Ltd.) Composed of Kaifeng Sinoma New Building Materials Co., Ltd.), one side of the base fabric is covered with a waterproof layer. The waterproof layer is a waterproof layer of self-adhesive material. The waterproof layer of self-adhesive material is prepared according to the mass ratio of the following components at a temperature of 150°C and a pressure of 6.5MPA for 2 hours. SBS modified asphalt (purchased from Hebei Baoli Chemical Technology Co., Ltd. Co., Ltd.): elastic asphalt (purchased from Hebei Baoli Chemical Technology Co., Ltd.): EVA resin (purchased from Shanghai Jiahao Adhesive Products Co., Ltd.) is 5:4:1.

Embodiment 2

[0024] This example is basically the same as Example 1, except that the waterproof layer of the self-adhesive material is prepared by copolymerization at a temperature of 160°C and a pressure of 6.5MPA for 3 hours.

Embodiment 3

[0026] This example is basically the same as Example 1, except that the waterproof layer of the self-adhesive material is prepared by copolymerization at a temperature of 170°C and a pressure of 6.5MPA for 4 hours.

Abstract

The invention belongs to the field of building engineering construction and in particular relates to self-adhesive stress cloth. The self-adhesive stress cloth comprises base cloth and a waterproof layer, wherein the base cloth is composed of alkali-free glass fiber yarns and polyester glass fiber cloth. The self-adhesive stress cloth disclosed by the invention can be constructed in autumn and winter or rainy seasons, and the seasonal construction problem is solved; the self-adhesive stress cloth disclosed by the invention is low temperature resistant, normal construction can be performed at atemperature of 0 DEG C or below, and the problem of construction difficulty at a low temperature is solved; the construction efficiency is effectively improved, the construction process is relativelycomplicated in the traditional construction process, while the construction process in the invention is simple; the self-adhesive stress cloth disclosed by the invention has ultrahigh tensile strength, namely two-way tensile strength reaching 50-150KN, and tearing strength, and also has creep resistance, aging resistance and corrosion resistance.

Description

technical field [0001] The invention belongs to the field of building engineering construction, in particular to a self-adhesive stress cloth. Background technique [0002] At present, with the popularization and development of modern building technology and new building material technology, the demand for stress cloth in the field of construction engineering is increasing, and the quality requirements are also getting higher and higher. However, in the current construction process, the traditional stress cloth not only requires a lot of manpower and material resources (construction equipment), but also the construction process is cumbersome. This will result in higher production costs for the construction unit, low construction efficiency, poor operability, and failure to meet market demand, which seriously hinders the development of stress cloth. [0003] In addition, the existing stress cloth is suitable for use in spring and summer. Because in the autumn and winter or ...
