Abstract

The invention discloses a penetrating glue applied to pipeline repair. Raw materials of the penetrating glue comprise, by weight, 80-120 parts of polyether, 2-8 parts of a plasticizer TXIB, 3-9 partsof a catalyst, 4-9 parts of silicate resin, 4-8 parts of a diluent, 2-6 parts of a silane coupling agent KH-570, 10-20 parts of a modified tackifier and 8-16 parts of a waterproof modification auxiliary agent. The invention further provides a preparation method of the penetrating glue applied to pipeline repair. The penetrating glue prepared by the invention has excellent flow penetration effect and good viscosity.

Description

technical field [0001] The invention belongs to the technical field of penetrating glue, and in particular relates to a penetrating glue used in pipeline repair and a preparation method thereof. Background technique [0002] In the case of local cracks, leakage, or damage to the pipeline, when emergency repair is required due to local damage to the pipeline, the CIPP local repair technology can be used to repair the pipeline. Scope of application: Influx of groundwater from leaks such as pipe joints and pipe walls; disconnection, damage, cracks, misalignment; mechanical wear; corrosion. Applicable pipe diameter: 100mm-1350mm. After using this technology to repair the damaged point, a high-strength new pipe combined with the old pipe can be formed, which is wear-resistant and corrosion-resistant, and can normally maintain a life span of more than 30 years. [0003] Repair the airbag, introduce resin-impregnated glass fiber cloth into the damaged part of the pipeline, fill t...
