Problems solved by technology

The fineness of the sericite used in this invention is 100~200nm. In this field, the fineness of sericite is generally 400~800 mesh, that is, 18000nm~38000nm. When the finer sericite is used, the phenomenon of post-thickening is very easy to occur. The use of sericite in this invention is obviously inapplicable. The phenomenon of agglomeration and deposition is easy to occur when adding physical fillers in the preparation of coatings. In this invention, modified Blending of sericite and modified sepiolite powder will easily cause the deposition of inorganic fillers, which will affect the uniformity and stability of the coating
In addition, in the actual application process, the paint toughness of this kind of paint is poor, and it is easy to fall off in the process of repeated wrinkles, losing the effect of paint

Abstract

The invention discloses a preparation method of a durable anti-aging water-based coating for rain gears, and belongs to the technical field of rain gear coatings. The preparation method includes the following steps: (1) preparation of modified composite filler and (2) preparation of a finished coating product. The prepared rain gear coating has good flexibility, excellent adhesion, high gloss, excellent wear resistance and excellent dulling resistance, and the defects of peeling, caused by repeated wrinkles during use, of the coating and reduction of anti-aging performance are overcome effectively.

Description

Technical field [0001] The invention belongs to the technical field of rain gear coatings, and specifically relates to a method for preparing long-lasting and anti-aging water-based rain gear coatings. Background technique [0002] Rain gear generally refers to all rain-shielding appliances, including raincoats, rain boots, umbrellas, tents, nano raincoat umbrellas, beach umbrellas, waterproof pants, air conditioning covers, etc. Nowadays, rain gear is not only used for sheltering the rain, but also for sunshade. Rain gear, especially umbrellas, nano raincoat umbrellas, beach umbrellas, etc., are mostly used in shrinking folding structures. Nowadays, in order to improve the anti-ultraviolet aging resistance of rain gear, they are mostly used in The surface of the rain gear is coated or sprayed with anti-ultraviolet aging paint to improve the performance of the umbrella. However, the reciprocating action of opening and folding is required during use, which leads to the phenomenon ...
