Common paper covers are generally completed by simple glue application, pressing and sewing. The leatheroid envelope produced by the simple method has the following defects: that is, the leatheroid envelope wrinkles and deforms when the product is subjected to high and low temperature tests. The phenomenon is often ignored by production enterprises and consumers, so that the quality of a large amount of notebook covers is unqualified, the service life of the covers and the appearance of products are seriously influenced, and the production requirement of high-end notebook covers is difficult to meet by a common production process.
The invention content is as follows:
the invention aims to overcome the defects in the prior art and provide a production process of a paper notebook cover which is not wrinkled and deformed.
The technical scheme adopted by the invention for realizing the purpose is as follows: a production process of a non-wrinkling and non-deforming paper-skin notebook cover, wherein the notebook cover is formed by sequentially compounding an outer leather layer, a paperboard and an inner leather layer, and the production process comprises the following steps:
(1) coating an adhesive layer on the inner surface of the outer leather layer, and standing for 10-20 minutes;
(2) taking a paper board with the water content of 6-15%, bonding the paper board with the adhesive layer on the inner surface of the outer leather layer, and performing first hot pressing after bonding, wherein the pressing force is 400 tons, the temperature is 40-60 ℃, and the duration time is 5-10 seconds;
(3) coating an adhesive layer on the inner surface of the inner leather layer, and standing for 10-20 minutes;
(4) bonding the inner surface of the inner leather layer with the outer surface of the paperboard, and then performing second pressing with the pressing force of 400-600 tons, the temperature of 40-60 ℃ and the duration of 5-10 seconds;
(5) carrying out edge sewing treatment on the composite product subjected to the second pressing, and then carrying out third pressing after the edge sewing treatment, wherein the pressing force is 400-600 tons, the temperature is 40-60 ℃, and the duration time is 5-10 seconds; and finishing the product manufacture.
The water content of the paperboard is preferably 7% -12%, the pressing force is 500 tons, and the temperature is 50 ℃.
The invention strictly controls the parameters of gluing, bonding time, water content of the paper board and the like, and is matched with a multi-time pressing mode, so that the produced paper wrapper not only has a stable and flat structure, but also is not wrinkled and deformed completely when high and low temperature tests are carried out and after the tests, the quality requirements of products and the market requirements of consumers can be met, and the service life of the products can be greatly prolonged.
Of course, according to the requirement of a specific notebook product, the cover can be made on the same outer leather layer for the front cover and the back cover together, or the front cover and the back cover can be made and molded separately and then used in combination.
The specific implementation mode is as follows:
the present invention will be further described with reference to the following specific examples.
Example 1
Firstly, cutting an outer leather layer, a paperboard and an inner leather layer into required shapes and sizes according to requirements; the water content of the paperboard is tested by using a water content tester, and the paperboard with the water content exceeding 15% needs to be subjected to dehumidifying treatment, so that the water content can be used within 6% -15%, and the optimal water content is controlled within 7% -12%.
(1) Coating an adhesive layer on the inner surface of the outer leather layer, and then standing for 10 minutes;
(2) taking a paperboard, bonding the paperboard with an adhesive layer on the inner surface of an outer leather layer, and performing first hot pressing after bonding, wherein the pressing force is 400 tons, the temperature is 60 ℃, and the duration time is 5 seconds;
(3) coating an adhesive layer on the inner surface of the inner leather layer, and then standing for 10 minutes;
(4) bonding the inner surface of the inner leather layer with the outer surface of the paperboard, and then performing second pressing, wherein the pressing force is 500 tons, the temperature is 40 ℃, and the duration time is 10 seconds;
(5) carrying out edge sewing treatment on the composite product subjected to the second pressing, and then carrying out third pressing after the edge sewing treatment, wherein the pressing force is 600 tons, the temperature is 50 ℃, and the duration time is 8 seconds; and finishing the product manufacture.
Example 2
(1) Coating an adhesive layer on the inner surface of the outer leather layer, and standing for 20 minutes;
(2) taking a paperboard, bonding the paperboard with an adhesive layer on the inner surface of an outer leather layer, and performing first hot pressing after bonding, wherein the pressing force is 600 tons, the temperature is 50 ℃, and the duration time is 5 seconds;
(3) coating an adhesive layer on the inner surface of the inner leather layer, and standing for 20 minutes;
(4) bonding the inner surface of the inner leather layer with the outer surface of the paperboard, and then performing second pressing, wherein the pressing force is 400 tons, the temperature is 50 ℃, and the duration time is 10 seconds;
