Abstract

The invention discloses a universal hot melt adhesive for bookbinding of book backs and book edges, and relates to the high-performance environment-friendly adhesive. The hot melt adhesive comprises the following components in parts by weight: 5-30 parts of an ethylene-vinyl acetate copolymer I, 5-30 parts of an ethylene-vinyl acetate copolymer II, 5-30 parts of an ethylene-vinyl acetate copolymerIII, 5-30 parts of petroleum resin I, 5-30 parts of petroleum resin II, 5-30 parts of petroleum resin III, 5-30 parts of petroleum resin IV, 5-30 parts of paraffin, 0-10 parts of polyethylene wax, 0-5 parts of an antioxidant I and 0-5 parts of an antioxidant II. The hot melt adhesive prepared by taking the ethylene-vinyl acetate copolymers (EVA) as the main materials is free of solvent or toxicity, belongs to environment-friendly products, has good bonding performance, tensile strength and elongation, and can be used as a back adhesive and an edge adhesive for wire-free bookbinding.

Description

Technical field: [0001] The invention relates to a high-performance environment-friendly adhesive, in particular to a general-purpose hot-melt adhesive for the back of bookbinding and a production method thereof. Background technique: [0002] Hot-melt adhesives do not use any solvents during production and application, are non-toxic, odorless, and do not pollute the environment, and enjoy the title of "green adhesive". In recent years, as the global environmental protection requirements have become higher and higher, hot melt adhesives have developed rapidly and are widely used in packaging, clothing, bookbinding, construction, furniture, electronics and shoemaking industries. Hot-melt adhesives are used for book binding, no need to lock the thread when binding books and periodicals, saving process, easy to operate, and suitable for high-speed continuous production, greatly improving production efficiency, so it has been widely used. According to the use of hot melt adhesi...
