Aerogel Coatings: Solving the Issues of External Wall Insulation Board Falling Off and Low Fire Resistance
Table of Contents
Hazards of Exterior Wall Insulation Materials
Current insulation materials, due to inherent defects and other reasons, exhibit phenomena such as cracking and detachment, leading to issues like easy cracking, water leakage, and accidents such as damaging vehicles and injuring people. Subsequent maintenance costs are higher, generating a significant amount of construction waste that impacts the city’s image. Additionally, the flammability of the materials, coupled with the risk of fire when they detach, poses further dangers.
Advantages of Using Aerogel Coating as Exterior Wall Insulation Material
1. Excellent Thermal Insulation and Energy Saving: A 3mm layer of aerogel insulation coating achieves a thermal resistance value of 0.8-0.9m²*K/W. Using a 3mm aerogel coating is equivalent to the insulation effect of a traditional 60mm insulation board.
2. Safety and Fire Prevention: Aerogel coating can reach fire protection grade A2. Its strong crack resistance prevents the cracking or detachment of the exterior surface caused by thermal expansion and contraction.
3. Environmental Friendliness: Aerogel coating is a nanoscale water-based coating that does not contain Volatile Organic Compounds (VOC), making it non-toxic and environmentally friendly.
4. Simple Construction Process: Traditional insulation materials require 7-15 construction steps, while the coating insulation system involves only 5 steps. Utilizing a spray application process reduces construction complexity, shortens construction periods, and ensures safety.
5. Excellent Sealing Effect: The aerogel coating forms a dense layer on the exterior wall, minimizing the risk of water leakage.
6. Minimal Exterior Wall Detachment: Due to the high viscosity of aerogel coating, it does not experience detachment issues even after years of use, unlike some other materials.
Introduction to Anchor-tech's Aerogel Insulation Coating:
The multi-layer thermal insulation coating system developed by Anchor-tech is based on three principles: ultra-high reflection, radiation, and blocking. It utilizes nanotechnology to prepare water-based nano solar reflective materials, aerogel water-based nano insulation coatings, and water-based nano rust-proof primers. These three functional water-based coatings work synergistically to provide insulation, heat resistance, waterproofing, and decorative functions for buildings. This coating system, using light and thin coatings, replaces heavy insulation boards.
