Experiment one: testing the data of book back fracture, page fall and opening angle of the calendar adhesive when the calendar adhesive is applied to a day;
the following description is required: the prior art generally adopts two adhesives for framing, namely hot melt adhesive and hydrosol adhesive; the data for comparing the parameters of the calendar adhesive of the present invention with those of the existing market are shown in the following table:
further note that: r is an angle which can be opened without pressing the binding line under normal page turning;
p is the force required for flattening the book back after being turned open and breaking the book back;
therefore, the adhesive solves the problems that the existing binding of the brushing adhesive for the wireless book back is inconvenient to read or easy to read but is easy to drop pages, especially the situation that the thickness of the spine is large, the reading is not completely influenced by the opening (hot melt adhesive) and the pages are easy to drop (common glue) due to the fact that the spine is large and the traditional glue is used for the current calendar products.
Experiment two: testing the mildew-resistant effect of calendar adhesives
Secondly, performing mildew resistance test according to a GB/T21866-2008 antibacterial coating (paint film) antibacterial performance measurement method and an antibacterial effect standard, wherein the test method comprises the following steps: after preparing 105cfu/ml of bacterial solution with the same amount of each fungus, the adhesives prepared in examples 1-3 and comparative example 1 were applied to a test board, dried and cured, and then the bacterial solution was applied to the cured adhesive, and the surface and the inside of the adhesive were observed to be mildewed after 10 days, 15 days and one month in a mold incubator at 35-40 ℃, and the test results are shown in the following table:
the calendar adhesive has the advantages that the calendar adhesive is high in bonding strength and flexibility of an adhesive film, good in weather resistance, high in mildew-proof effect, long in service life and free of mildew after being used for a long time;
it should be noted that: the special calendar adhesive is mainly used in 2 links of book back processing: firstly, the adhesive is brushed after the book block is bound with the book, and firstly, the adhesive is brushed on the back cloth when the back cloth is pasted;
after use, the adhesive can be directly used for book pressing and bonding, and can also be used for constant-pressure back pressing, and the operating temperature of the adhesive is as follows: at 15-25 ℃, temperatures below 8 ℃ may lead to a significant decrease in adhesion, temperatures below 4 ℃ may lead to failure, the storage temperature of the adhesive: 5-45 ℃.
