Abstract

A hot melt adhesive for book binding is prepared from raw materials in parts by weight as follows: 10-25 parts of paraffin wax, 30-60 parts of an ethylene vinyl acetate copolymer, 15-25 parts of terpene, 5-10 parts of rosin, 3-5 parts of styrene-butadiene rubber, 0.25-0.8 parts of an antioxidant and 10-15 parts of pentaerythritol. The hot melt adhesive for book binding is pollution-free, wide in adhesion surface, fast to cure, drying-free and convenient to use, and can solve the problem that books with larger thickness cannot be bound due to poor liquidity, yellow color and small adhesion force of the conventional hot melt adhesive for book binding.

Description

technical field [0001] The invention belongs to the technical field of hot-melt adhesives, and in particular relates to a hot-melt adhesive for bookbinding and a production method thereof. Background technique [0002] In recent years, hot-melt adhesives for bookbinding have developed rapidly, and more and more bookbinding factories use hot-melt adhesives to bond books. This process has become the main method for binding books, and there is a tendency to further expand the scope of use in the future. , Market demand has promoted the rapid development of hot-melt adhesives for bookbinding. The development process of binding materials for books and periodicals is from the use of flour paste-synthetic resin glue polyvinyl acetate-polyvinyl alcohol-hot melt adhesives, especially the emergence of hot melt adhesives has greatly improved the speed of book binding processing and shortened the time for publishing books. cycle, adapted to the needs of publishing and society.
