The invention provides a technology for producing flame-retardation glass fiber composite cloth, which belongs to the technical field of a textile industry. The technology solves the problem of low production efficiency in the prior art. The technology comprises the following steps: a) braiding: performing plain weaving on glass fiber filament to obtain the basic glass fiber cloth; b) dipping: immersing the basic glass fiber cloth in the step a) in slurry for 5-6 hours; c) solidification: performing UV solidification on the dipped basic glass fiber cloth in the step b); d) surface cloth acquisition: selecting the non-woven fabric on market and processing the non-woven fabric, coating the non-woven fabrics with a flame-retardation paint, and drying the material to obtain the flame-retardation surface cloth; e) applying: applying the glass fiber cloth through UV solidification in the step c) through an applying apparatus and the flame-retardation surface cloth to obtain the flame-retardation semi-finished product glass fiber cloth; f) printing and dyeing: placing the flame-retardation semi-finished product glass fiber in a fabric printing and dyeing apparatus for printing and dyeing;and g) drying. The technology has the advantages of increasing production efficiency.
