Rainproof fabric coating and rainproof fabric production process

The invention discloses a rainproof fabric coating and a rainproof fabric production process, and belongs to the field of textiles. The rainproof fabric production process comprises the following steps of S1, performing material preparation: weighing the following raw materials in parts by weight of 20-30 parts of a waterborne polyurethane emulsion, 1-2 parts of a foaming agent, 70-80 parts of water, 2-3 parts of a thickening agent and 1-1.5 parts of an accelerant; S2, performing material mixing: sequentially adding the waterborne polyurethane emulsion, the water, the foaming agent, the accelerant and the thickening agent prepared in the step S1 while stirring, and until a glue material is mixed to be in a paste shape, forming glue; and S3, performing machine coating: uniformly coating cloth with the glue prepared in the step S3 in a scraping manner, and carrying out drying and curing to obtain a rainproof fabric. According to the rainproof fabric coating and the rainproof fabric production process disclosed
