A new process for binding hardcover book printing China, which use EVA environment-friendly resin sheet and ordinary backing paper as composite material to replace traditional hardcover books and notebook cover materials; The specific process includes the following steps:

Firstly, book blocks production. Including book block printing, folding, matching pages, locking;

Step 2, book covers production. The composite cover material is included. EVA environment-friendly resin sheet is made of new environment-friendly a material and the width of the mold is no more than 1m. Common backing paper adopts 190g ~ 250g card paper, paper thickness 0.20mm ~ 0.3mm(±0.03mm); Compound glue, water-soluble environmental protection glue; Cover composite size: 25g ~ 35g/ m2, adhesive strength: ≥10N/50mm, thickness: 1.15mm(±0.05mm), appearance: uniform thickness, no foreign body, oil, hard, no wrinkle, no sag, or bulge; Cutting printing, cover printing equipment requires 7+1 or more UV printers (except white EVA materials, white EVA materials can use 4+1 or more UV printers); The process requires 3 sets of white ink (except white EVA material), and polychromatic printing;

After the process processing, the situation of UV varnish, must use the oil base aniliculus roller + resin plate printing technology, in order to increase the abrasion resistance of the graphic and text parts of the printing without damaging the texture of EVA; Die-cutting, indentation, indentation steel line mining thickness of 1.0mm ~ 1.3mm;

Step 3, the cover and book block adhesive clamping finalize the design; Cover and book block adhesive clamping finalize the design of the plastic must choose more than 15 head of plastic dragon equipment.

Step 4, cut the finished product, cut the finished product must use three sides of the machine knife a cut shape.

EVA is an Ethylene - Vinyl Acetate copolymer (also known as Ethylene - Vinyl Acetate copolymer), which is prepared by copolymerization of Ethylene (E) and Ethylene Acetate (VA). EVA environmental protection resin sheet has resilience and high resistance to tension, high toughness, good shockproof, buffer, heat insulation, heat preservation protective performance and excellent low temperature resistance, resistant to cold and exposure, airtight bubble hole, sound insulation effect is good, airtight bubble pore structure, non-absorbent, moisture-proof, good water resistance, resistance to sea water, oil, acid, alkali and other chemical corrosion, antibacterial, non-toxic, tasteless, no pollution. EVA resin sheet with ordinary paper composite instead of the traditional hardcover book cover material. The new material has the advantages of softness, high resilience, dirt resistance, water resistance, low density, light quality and simple production technology, which can well solve the shortcomings of traditional hardcover books and notebooks. It has greatly reduced the consumption of natural resources and the waste of human resources. Although embodiments of the invention have been shown and described, it is understandable to the general technical personnel in the field that such embodiments may be varied, modified, replaced, and modified in a number of ways without deviating from the principle and spirit of the invention, and that the scope of the invention is limited by the accompanying claims and their equivalents.

Technical summary:

The invention discloses a new process method for binding hardcover books and notebooks, which adopts EVA environment-friendly resin sheet and ordinary backing paper to compound and replace the traditional cover materials of hardcover books and notebooks; The specific process includes the following steps: book block production including book block printing, folding, page matching, locking; The production of book cover including cover material composite, slitting, printing, post processing, die-cutting, indentation; Cover and book block adhesive clamping set; Trim finished product. The invention has simple manufacturing process and low cost; The new material has the advantages of softness, high resilience, dirt resistance, water resistance, low density, light quality and simple production technology, which can well solve the shortcomings of traditional hardcover books and notebooks. It has greatly reduced the consumption of natural resources and the waste of human resources.
