Anti-icing coating fabric for membrane structure building, and preparation method thereof

Abstract

The present invention provides an anti-icing coating fabric for a membrane structure building, and a preparation method thereof. The coating fabric comprises an anti-ice coating, an optical substrate layer, a polytetrafluoroethylene coating, a fiber layer, an adhesive layer and a welding layer. The thickness of the anti-ice coating is 10-25 mum, and the filled materials of the anti-ice coating comprise, by mass, 1.5-4.5% of hollow glass beads with the diameter of 2-8 mum, and 1.5-3% of polytetrafluoroethylene of SiO2, wherein the particle size of the polytetrafluoroethylene of the SiO2 is 30-60 nm. The thickness of the optical substrate layer is 30-70 mum, and the filled materials of the optical substrate layer comprise, by mass, 2-4% of TiO2 with the particle size of 60-80 nm, and 1-1.5% of polytetrafluoroethylene of ZnS, wherein the particle size of the polytetrafluoroethylene of the ZnS is 30-50 nm. The anti-icing coating fabric of the present invention has the following advantages: the anti-icing performance and the cold resistance of the membrane structure are increased; the formula is simple, only the inorganic filler is required to add, and no long-time chemical reaction is required; the main processing processes of various steps are the same, and the process has strong controllability.

Description

technical field [0001] The invention belongs to the field of material technology, and in particular relates to an anti-icing coating fabric for membrane structure buildings and a preparation method thereof, which are mainly used in the construction industry and can also be used in aviation vehicles. Background technique [0002] Contemporary, with the continuous development of material technology, the acoustics, optics, internal temperature control and other problems of the coated fabric structure have been well solved, the flexible architectural membrane structure has become a new architectural form, its unique mechanical properties It can provide people with various architectural structures, so that people can get a new visual experience. Due to the thin thickness of the coated fabric, the membrane structure is different from the thicker walls of the reinforced concrete structure. Even if the thermal insulation coefficient of the coated fabric itself is high, its thermal i...

Problems solved by technology

However, the design of coated fabrics needs to consider many factors comprehensively. Reducing the infrared emissivity of the material alone will cause the heat absorbed by the membrane structure during the day to be unable to dissipate, which will greatly increase the temperature inside the membrane structure and affect the internal comfort.
