Benefits of technology

This patented technology has been developed for creating an environmentally friendly waterproof coat that can be easily applied without any binder or other materials used during application. It also includes various technical features such as safety concerns associated with it's use, cost savings due to its low content of organic solvents (no binding agents), easy applicability at different temperatures, and ease of clean up after usage.

Problems solved by technology

This patented describes how we can create an improved rubbing cloth that prevents dirt particles from sticking onto its surfaces while still being comfortable for workers in their worksites. Additionally, there are concerns about environmental issues caused by excessively wetting the fabric with oil or other liquids used overcoat layers when applied without causing them to stick out too much.

Embodiment 1

[0016] Firstly, the substrate is treated with an aqueous surfactant solution, which is an aqueous solution of sodium dodecylbenzenesulfonate with a concentration of 7%. It is then compounded with the coating and finally dried.

[0017] Coating formula: water-based silicone modified acrylic resin 35%, water 40%, aluminum oxide 10%.

[0018] The vibration mass loss rate after airgel felt + coating is 0.05%

[0019] The thermal conductivity of airgel felt + coating is 0.022w / m.K.

Embodiment 2

[0021] Add a wetting agent to the coating, directly compound with the airgel felt, and dry.

[0022] Coating formula: 42% acrylic emulsion, 35% water, 9% tin dioxide, 1% polyether modified silicone

[0023] The vibration mass loss rate after airgel felt + coating is 0.07%

[0024] The thermal conductivity of airgel felt + coating is 0.0215w / m.K.
