The invention discloses an awning cloth coating technology. The technology comprises steps as follows: (a), coating slurry is prepared; (b), base cloth is processed; (c), the base cloth is dried; (d), the base cloth is calendered; (e), the coating slurry is transferred; (f), a thin film and the base cloth are overlapped; (g), awning cloth initial fabric is subjected to water-proof finish; (h), the awning cloth initial fabric is detected; (i), the awning cloth is trimmed, and a finished product is obtained. According to the awning cloth coating technology, chemical additives are added to polyvinyl chloride paste resin, so that the performance of the coating slurry is improved, the base cloth can be rapidly coated with the thin film in a base cloth coating process, the coating is even and reliable, the coating time is short, the thickness of the thin film can be controlled, and the thickness and the breadth of the finished product of the awning cloth are effectively controlled; the preparation efficiency of the awning cloth is improved, the awning cloth has waterproof, mould-proof, cold-resistant, anti-aging, anti-static properties and other properties, besides, breaking strength, tearing elongation and tearing strength of the awning cloth are greatly superior to those of traditional awning cloth, the quality of the finished product of the awning cloth is wholly improved, and demands of users are met.
