Referring to fig. 1-7, an environment-friendly paperboard comprises a paperboard body 1, wherein the paperboard body 1 comprises a bottom paper 11, corrugated paper 12 and a top paper 13 which are stacked in sequence, specifically, the bottom paper 11 and the top paper 13 are of rectangular flat-plate paper structures which are arranged in parallel, the corrugated paper 12 is parallel to the bottom paper 11, the top surface of the corrugated paper 12 is connected with the top paper 13, the bottom surface of the corrugated paper 12 is connected with the bottom paper 11, when the paperboard is actually used for forming a container such as a paper box, the bottom paper 11 faces to the outside, the top paper 13 faces to the inside, the bottom paper 11 serves as an outer layer of the paperboard and the paper box, and when the paperboard is bent, the corrugated paper 12 prevents bending trend by utilizing the self structural characteristics, so that the structural strength of the paperboard body 1 is improved;
for the purposes of advertisement, internal article identification and the like, a paper box is usually formed by using paper board firstly, and then patterns are printed on the surface of the paper box by using ink, therefore, the middle part of the paper board body 1 is penetrated and provided with a printing part 2, the printing part 2 comprises printing paper 21, corrugated paper 12 and inner layer paper 22 which are sequentially stacked, the outer surface of the printing paper 21 is level with the outer surface of the bottom paper 11, the inner surface of the printing paper 21 protrudes from the inner surface of the bottom paper 11, and the patterns are printed on the printing paper 21;
specifically, the printing part 2 is similar to the paperboard body 1 in whole, and is of a rectangular structure in a sheet shape, a through hole with the same area as the bottom surface of the printing part 2 is dug in the middle of the paperboard body 1, the printing part 2 is arranged in the through hole, the side edge of the printing part 2 is connected with the through hole of the paperboard body 1 and is integrally formed, specifically, the edges of the bottom surface paper 11 and the printing paper 21 are connected with each other, the edges of the inner layer paper 22 and the top surface paper 13 are connected through paper materials, meanwhile, the thickness of the printing paper 21 is larger than that of the bottom surface paper 11, when the outer surface of the printing paper 21 is flush with the outer surface of the bottom surface paper 11, the inner surface of the printing paper 21 protrudes from the inner surface of the bottom surface paper 11, and the thickness of the inner layer paper 22 is the same as that of the top surface paper 13, so that the whole thickness of the printing part 2 is larger than that of the paperboard body 1, and the top surface of the printing part 2 protrudes from the top surface paper 13 of the paperboard body 1, and when the paperboard is used, the outer surface of the paperboard forming a paper box is flush with part protruding from the other parts of the inner surface of the paperboard;
for the patterns on the printing paper 21, in the paper board production process, the printing ink is printed by an ink jet printer to form a pattern layer on the outer surface of the printing paper 21 of the printing part 2, and the information displayed by the pattern layer is the patterns on the paper board;
after the cardboard box formed by the cardboard is needed to be vertically put into the cardboard, the goods possibly collide with the protruding part in the putting process, so that the printing part 2 is damaged, therefore, alternatively, the part of the printing part 2 protruding out of the cardboard is smoothly connected with other parts of the inner surface through a slope, after the slope with smooth transition is arranged, the goods collide with the slope part before colliding with the protruding part, at the moment, the slope disperses the collision impact force, so that the collision intensity of the goods and the printing part 2 is reduced, the overall structural strength and the durability of the cardboard are improved, the reusability is improved, and the environmental protection is improved;
for the purpose of environmental protection, the cardboard box formed by the cardboard can be used for many times in actual use, when the cardboard box is used for different times, the patterns printed on the surface of the cardboard box are different, for the cardboard box or the cardboard box printed with the patterns in the prior use, the common method is to directly scrape off or take off the part of the surface layer printed with the patterns, but scrape off the layer structure printed with the printing ink, although the purpose of removing the printing ink patterns and adding new patterns can be achieved, the whole thickness of the cardboard is reduced in the scraping process, and the strength of the whole structure is further reduced, therefore, the patterns formed by the thermal shedding printing ink are printed on the printing paper 21;
specifically, the thermal stripping ink is a common ink jet ink, the adhesive force of the ink can be reduced in an environment of 90-110 ℃, and in the embodiment, the ink jet ink comprises the following components: 10-25% of light-excited fluorescent colorant, 1-10% of polymer resin, 65-80% of organic solvent and 1-4% of antistatic agent; when the old pattern is needed to be printed after one-time use, when the pattern on the paper box is changed, the outer surface of the printing paper 21 of the printing part 2 can be locally heated, when the temperature is 100 ℃, the adhesive force of the printing paper is reduced, the printing ink can be stripped, alternatively, an operator can lightly scrape the printing ink with reduced adhesive force by scraping or smear a small amount of solvent at the position of the pattern layer to assist the stripping of the printing ink, reprinting can be carried out after scraping, a new pattern layer is formed by printing, the displayed information of the new pattern layer is different from the scraped pattern layer, a new pattern is formed, the paper box is printed and refreshed, the new paper box is not needed to be replaced, meanwhile, because the thickness of the printing paper 21 is larger than the thickness of the bottom paper 11, when the printing paper 21 is required to be stripped by lightly scraping, the printing paper 21 can bear more scraping times compared with the general corrugated paper 12 without influencing the structural strength;
through printing the pattern that the thermal release printing ink constitutes on printing paper 21, can be when show pattern information, under the circumstances that needs reuse, can directly make old pattern peel off and print the refreshing pattern through the mode of heating, simultaneously through setting up printing portion 2 that printing paper 21 thickness is greater than bottom paper 11 thickness, even if need scraper or organic solvent assist when peeling off, thicker printing portion 2 is to scraping or under the influence of organic solvent, the structural strength change is less, maintain structural strength when the repetition printing, reduce the reuse number of times decline because structural strength leads to, and then the probability that the environmental protection is insufficient that leads to, the holistic environmental protection of cardboard has been improved.
In the above structure, although the printing part 2 and the cardboard body 1 are integrally connected, the corrugated paper 12 is still arranged in the printing part 2, and when the corrugated paper 12 is extruded, the corrugated paper 12 is connected with other structures to further strengthen the rest of the cardboard, namely the overall structural strength of the cardboard is related to the connection area between the corrugated paper 12 and the other structures, meanwhile, the corrugated paper 12 of the printing part 2 and the cardboard body 1 is not aligned due to the inconsistent thickness of the printing paper 21 and the bottom paper 11, so that the overall structural strength of the corrugated paper 12 of the two parts is reduced, and a plurality of separation layers are arranged between the printing part 2 and the cardboard body 1 and are perpendicular to the bottom paper 11 to further strengthen the overall structural strength of the cardboard;
specifically, since the cardboard body 1 and the printing portion 2 are both rectangular, four sides of the printing portion 2 disposed in the cardboard body 1 are all connected with the cardboard body 1, therefore, four connected sides correspond to four isolation layers, each isolation layer is a strip cardboard, the length of one edge of the printing portion 2 is equal to the length of the corresponding isolation layer side of the edge, the width is equal to the thickness of the cardboard body 1, at this time, the isolation layers can completely cover the cross sections of the cardboard body 1 and the printing portion 2, the corrugated paper 12 of the printing portion 2 and the cardboard body 1 are both connected with the isolation layer, and the corrugated paper 12 is connected with the isolation layer in addition to the contact with the parallel paperboards on both sides;
