Abstract

The invention discloses a preparation method of an environment-friendly fabric coating for travel bags and suitcases. The environment-friendly fabric coating is prepared from the following raw materials in parts by mass of 60-80 parts of polymer dihydric alcohol, 10-20 parts of diisocyanate, 1-2 parts of a catalyst, 1-2 parts of a plasticizer, 3-6 parts of a neutralizer, 120-160 parts of deionized water, 10-20 parts of nano silicon dioxide, 8-15 parts of epoxidized soybean oil, 10-15 parts of acetone and 2-8 parts of a cross-linking agent. The preparation process is simple; in the finished environment-friendly fabric coating, the nano silicon dioxide and the epoxidized soybean oil are adopted, and a waterborne polyurethane emulsion prepared according to a reasonable ratio is matched and utilized to replace traditional organic latex, so that the fabric coating is non-toxic, odorless, good in stability, environment-friendly, pollution-free and very suitable for being used in tourist attractions.

Description

technical field [0001] The invention relates to the technical field of fabric coating, in particular to a method for preparing an environment-friendly fabric coating for travel bags. Background technique [0002] Coated fabric is a kind of fabric treated by special process, which can form a layer of uniform covering glue on the surface of the fabric, so as to achieve waterproof, windproof and other functions.
