Abstract
Provided is a high-strength hardcover book flat spreading back adhesive. The back adhesive is prepared from paraffin, Fischer-Tropsch wax, maleic anhydride-grafted EVA, acrylic resin, EVA with the high VA content and the like according to a certain proportion. A preparation method of the back adhesive comprises the steps that 1, the temperature of a stirring kettle is increased to about 110 DEG C, the paraffin and the Fischer-Tropsch wax are added in proportion, and stirring starts to be conducted till the materials are completely dissolved; 2, when the temperature is increased to 140 DEG C, the maleic anhydride-grafted EVA, the acrylic resin, and the EVA with the high VA content are added into the kettle in proportion, the stirring kettle is immediately vacuumized till the vacuum degree ranges from minus 0.1 MPa to 0.5 MPa, the temperature is controlled to reach 160 DEG C, and stirring is conducted till the materials are completely dissolved; 3, vacuumizing is stopped, emptying is conducted, hydrogenated C5 petroleum resin and part of disproportionated hydrogenated natural tackifying resin are added in proportion, vacuumizing continues to be conducted by switching on a vacuum valve, stirring is conducted till the materials are completely dissolved, and heat preservation is conducted for 30 minutes; 4, after emptying is finished, whether an adhesive body is completely fused or not is detected, heating is stopped when the adhesive body is completely fused, and adhesive obtaining is prepared when the temperature is lowered to 120 DEG C; 5, adhesive obtaining is conducted after it is inspected that the adhesive obtaining process is qualified.
Description
Technical field
The invention belongs to field of adhesive technology, specifically refer to a kind of hard-cover books and divide high intensity gum and preparation method thereof.
Background technology
In recent years, developing rapidly with electronic product, much traditional recording mode changes gradually, and edition binding notebook seems thick and heavy, not portable, the light of handwritten book gradually gets the favour of people, and traditional handwritten book can not be divided, make to write conveniently, and waste and write space, with the raising of people's quality of life, divide the accreditation that handwritten book obtains people.
Divide books and periodicals glue and be mainly used in write by hand notebook gluing, be characterized in making write by hand instinct divide, facilitate page turning and written record, increase the usable floor area of paper, be the direction of write by hand notebook printing.In the market divide what books and periodicals glue was mainly made with PUR for matrix resin, also have the PUR being made into for matrix resin with thermoplastic elastomer (TPE), but the said goods cost of material be too high, and elastomeric material summer unstable properties.
Content of the invention
It is an object of the invention to overcoming above-mentioned deficiency present in prior art, and provide a kind of high intensity, high-flexibility, high resilience, resistance to low temperature is superior, and high intensity gum and preparation method thereof divided by the hard-cover books of low cost.
