Abstract

The invention relates to a novel adhesive for adhesive sticker. The novel adhesive for the adhesive sticker consists of the following raw materials in parts by weight: 6 to 12 parts of iso-tridecanolpolyoxyethylene ether, 30 to 40 parts of dibutyl phthalate, 40 to 50 parts of polyvinyl formal of 15 percent, 20 to 24 parts of copper oxide, 18 to 22 parts of aluminum hydroxide, 8 to 14 parts of sodium hexametaphosphate, 20 to 30 parts of modified epoxy resin, 10 to 12 parts of hydroxyethyl saponin gum, 8 to 12 parts of hydroxy propyl cellulose and 30 to 38 parts of emulsifier OP-10. The novel adhesive for the adhesive sticker has the following beneficial effects: (1) the adhesive is environmentally-friendly in component, harmless for a human body in the production process, high in adhesionproperty, not liable to remove and excellent in durability; and (2) the adhesive has high waterproof property, high-temperature resistance and wide application range, is suitable for paper labels to use and is also suitable for wood and film plastic to use.

Description

technical field [0001] The invention belongs to the field of self-adhesives, and in particular relates to a novel adhesive for self-adhesives. Background technique [0002] Self-adhesive, that is, self-adhesive label material, is a composite material that uses paper, film or special materials as the fabric, adhesive on the back, and silicon-coated protective paper as the backing paper. [0003] Due to the variety of coating techniques, the formation of self-adhesive materials has different grades. The current development direction is from traditional roll coating and doctor blade coating to high-pressure casting coating, so as to ensure the coating quality to the maximum extent. Uniform sensibility, avoiding the generation of air bubbles and pinholes, and ensuring the coating quality, while the domestic technology of casting cloth coating is not yet mature, and the traditional roll coating is mainly used in China. [0004] Adhesive bonding (bonding, bonding, cementation, gl...
