Abstract

The invention relates to a fiber spray coating structure with a surface coating. The fiber spray coating structure comprises a fiber spray coating. The surface of a base layer is coated with the fiberspray coating. The fiber spray coating structure is characterized by further comprising the surface coating, and the surface of the fiber spray coating is coated with the surface coating. Pores are formed between surface layer particles of the surface coating, so that the porosity is high, the sound transmission effect is good, and the good sound absorption and noise reduction effects of the fiber spray coating are ensured without being damaged and reduced. The surface coating has high strength and is water-tolerant. The fiber spray coating structure with the surface coating can be cleaned through a dust collector or a water gun. The problem that a fiber spray coating cannot be cleaned after getting dirty after long-time use is solved. The fiber spray coating structure with the surface coating has the lower cost and higher cost-performance ratio. The surface coating is good in heat preservation and insulation performance, high in corrosion resistance and stable in chemical property. In the possession of the excellent performance, the fiber spray coating structure with the surface coating is easy to construct and facilitates production practice.

Description

Technical field [0001] The invention relates to the field of building construction, in particular to a fiber spraying structure with a surface coating and a preparation method thereof. Background technique [0002] Fiber spraying is a cost-effective functional coating in the construction field, which integrates multiple functions such as sound absorption and noise reduction, fire prevention and heat preservation. Because of this feature of integrating multiple functions into one, it has been promoted quickly in China and more and more applications. However, fiber spraying also has the shortcomings that the surface is not resistant to dirt, and cannot be processed after absorbing dust and can only let its look and feel deteriorate. [0003] The patent document "Sound-absorbing coating structure and construction method for computer room" with the application number CN201710561910.0 proposes a structure of "sound-absorbing cotton coating + protective surface layer", but the surface l...
