Abstract

The invention discloses an antirust anti-oxidation water-borne impervious sealant for a container. The sealant is made from the following raw materials, by weight part, 40-60 of a polyacrylate emulsion with the solid content being 40-50%, 5-10 of polychloroprene latex with the solid content being 40-50%, 3-5 of EP-44 water-borne epoxy resin emulsion with the solid content being 40-50%, 3-5 of rosin, 2-4 of liquid paraffin, 3-5 of a titanate coupling agent, 40-60 of barite powder, 3-5 of tributyl citrate, 0.5-1 of potassium sorbate, 0.5-1 of inositol hexaphosphate, 0.5-1 of glyceride citrate, and 10-15 of water. The sealant for a container is high in elasticity, good in water resistance and impermeability and excellent in sealing performance. The sealant has antirust and anti-oxidation effect, is good in durability and long in service life, and is green and eco-friendly.

Description

technical field [0001] The invention relates to the technical field of sealants, in particular to an anti-rust, anti-oxidation, water-based and impermeable container sealant and a preparation method thereof. Background technique [0002] Sealant is a sealing material that guides the deformation with the shape of the sealing surface, is not easy to flow, and has a certain adhesiveness. It is an adhesive used to fill the configuration gap to play a sealing role. play an important role. In recent years, with the rapid development of the container transportation industry, sealant, as the main auxiliary material in the container manufacturing process, has also received more attention on its performance. Traditionally, solvent-based butyl rubber or neoprene sealants are used for container sealing. These types of sealants have heavy odor and large VOC emissions, which may cause environmental pollution and even harm to the human body, failing to meet environmental protection requir...
