Abstract

The invention discloses a surface waterproofing protection agent, and preparation and application methods thereof. The surface waterproofing protection agent comprises the following raw materials by mass: 10 to 20% of triisopropylsilane, 2 to 10% of butyl silicate, 13 to 20% of n-octyltriethoxysilane, 8 to 14% of isooctyltriethoxysilane, 3 to 9% of metasilicic acid and 9 to 16% of a coupling agent, with the balance being water. The invention also discloses preparation and application methods for the surface waterproofing protection agent. The surface waterproofing protection agent provided bythe invention can effectively deal with the capillary action of porous materials, prevents water and other ions to enter material with air wrapping characteristics through cracks and capillary action,and allows the durability of the materials to be substantially improved. The application method for the surface waterproofing protection agent is simple. The surface waterproofing protection agent can be directly sprayed onto the surface of a constructed material with air wrapping characteristics, has flame retardation performance, and is free of toxicity, peculiar smell, pollution and side effect on construction workers.

Description

technical field [0001] The invention relates to a surface waterproof protectant and its preparation and application method. Background technique [0002] The characteristic material arresting system is a safety facility arranged in the safety zone at the end of the runway, which uses the energy-absorbing properties of the collapsed material to block the aircraft rushing into it. Its width is consistent with the runway, and its length is tens of meters to Between more than a hundred meters. [0003] The cast-in-place characteristic material arresting system is to fully mix special hydraulic gelling materials, admixtures, water and foaming agents according to a certain proportion to prepare foam slurry, which flows into the arresting bed at the end of the runway by itself through the conveying pipeline, and forms after hardening. An air-wrapped aircraft arresting safety feature with a specific damping coefficient. [0004] Due to various reasons, there will be a large number...
