Abstract

The invention relates to a coating material and a preparation method thereof, particularly a recyclable coating material and a preparation method thereof. The coating material is composed of the following components in parts by weight: 100 parts of corn starch, 8-16 parts of carboxyethyl cellulose, 3-8 parts of alkyd resin, 12-20 parts of low density polyethylene resin, 3-8 parts of glycerol, 4-10 parts of calcium stearate, 1-5 parts of liquid paraffin, 1.0-1.6 parts of calcium propionate, 1.2-1.8 parts of titanium white, 0.5-0.8 part of reinforced modifier, 0.1-0.5 part of stabilizer and 0.2-0.6 part of initiator. The coating material solves the problem of low degradability of the coating material in the prior art, implements recycling, protects the environment and saves the resources.

Description

technical field [0001] The invention relates to a coating material and a preparation method thereof, in particular to a recyclable coating material and a preparation method thereof. Background technique [0002] Laminating, also known as "overplastic", "mounting glue", "film sticking", etc., refers to the use of transparent plastic film to apply heat and pressure to the surface of printed matter to protect and increase gloss. Laminating film has been widely used for surface binding and protection of book covers, picture albums, commemorative albums, postcards, product brochures, calendars and maps. At present, common film-coated packaging products include cartons, cartons, handbags, fertilizer bags, seed bags, self-adhesive labels, etc. [0003] Lamination is to put a layer of film on the outer packaging of the product to make the appearance of the product more beautiful, shiny, and dirt-resistant. There are many products that need this process, such as the outer packaging ...
