Abstract
The invention discloses an EVA (ethylene vinyl acetate copolymer) hot melt adhesive for paper. The EVA hot melt adhesive mainly comprises 18-22 parts of EVA resin, 2-4 parts of low-molecular-weight polyethylene, 18-22 parts of thermoplastic phenolic resin, 8-10 parts of DBP (dibutyl phthalate) and 4-6 parts of calcium carbonate. EVA resin, low-molecular-weight polyethylene, thermoplastic phenolic resin, DBP and calcium carbonate are mixed, stirred for 20 minutes at the temperature of 60 DEG C andthen slowly heated to reach 120 DEG C, the mixture is cooled naturallyto reach a normal temperature after keeping the temperature for 20 minutes, and the EVA hot melt adhesive is prepared. The adhesive strength of the hot melt adhesive for paper meets requirements, and the wear resistance of a book spine formed after the hot melt adhesive is congealed and solidified is good, so the pages of a book are protected against being scattered when the book falls off.
Description
Technical field
The present invention relates to hot melt adhesive field, specifically a kind of paper EVA hot-melt adhesive.
Background technology
Hot melt adhesive take thermoplastic resin as base-material, adds properties-correcting agent, softening agent, weighting agent and anti-aging agent etc. and process.Compared with other sizing agents, hot melt adhesive, originally as solid, has and is convenient to packaging, transport, storage; Solvent-free, pollution-free, hypotoxicity and bond strength is large, curing speed fast, can realize the advantage of high-speed job.
There is two problems in existing paper hot melt adhesive: one is that cohesive strength that page is bonded together is inadequate in wireless perfrct binding; Two is after hot melt adhesive condensation cured, and the spine of formation wears no resistance, and easily scatters when protecting books and falling.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of paper EVA hot-melt adhesive, by vinylformic acid, modification is carried out to inorganic combustion inhibitor, reduce the impact of inorganic combustion inhibitor on EVA hot-melt adhesive mechanical property.
In order to achieve the above object, the present invention by the following technical solutions: a kind of paper EVA hot-melt adhesive, its composition mainly comprises:
EVA resin 18-22 part,
Low molecular weight polyethylene 2-4 part,
Novolac resin 18-22 part,
DBP 8-10 part,
Calcium carbonate 4-6 part.
A kind of method preparing above-mentioned paper EVA hot-melt adhesive, comprise the following steps: disposable by EVA resin, low molecular weight polyethylene, novolac resin, DBP, calcium carbonate mixing, stir 20 minutes at 60 DEG C, slowly be heated to temperature again and reach 120 DEG C, constant temperature is naturally cooling after 20 minutes, namely completes preparation after being cooled to normal temperature.
The invention has the beneficial effects as follows: a kind of paper hot melt adhesive provided by the invention, cohesive strength satisfies the demands, and the spine wear resistance formed after hot melt adhesive condensation cured is good, is unlikely and scatters when protection books are fallen.
