Experimental data
Table 1 whitening qualitative basic comparative study
The test data in Table 1 show that the latex paste adhesive for shoes, which uses the dispersing agents NNO, casein and borax, can generate the phenomenon of whitening of the surface of the adhesive paste during the natural light storage process of the adhesive shoe product. Therefore, the following study was conducted only for the work of removing these three materials.
Table 2 study of formulation properties
Table 2 shows that the best formulation that does not cause blushing of the rubber shoe slurry is 20 parts natural latex, 30 parts environmentally friendly adhesive, 6 parts grafted latex, 1.0 part 50% peregal in O-form, 0.5 part ammonia, 1.0 part water-based colorant, and 6 parts thickening stable mother liquor. The best adhesive strength is achieved.
2. Study of the preparation Process
1. Research on preparation process of thickening stable mother liquor
(1) Proportioning research
TABLE 3 Table 3
The results are shown in Table 3: the basic formula of the thickening stable mother solution is sodium carboxymethyl cellulose 5, soft water 60, potassium hydroxide 0.5 and mildew inhibitor BCM 0.1.
(2) Study of manufacturing Process
TABLE 4 Table 4
The results in Table 4 show that the optimal preparation process of the thickening stable mother liquor is: 5 kg of eagle brand sodium carboxymethyl cellulose (CMC) and 0.1 kg of mildew inhibitor BCM are added into a stirrer filled with 20 kg of soft water and 0.5 kg of potassium hydroxide in a sprinkling state under stirring. After all CMC powder is swelled in water, 20 kg of soft water is added twice under the stirring condition, and the materials are stirred until the materials are fully dispersed into uniform thick bodies.
2. Processing study of Mixed mother liquor
The method comprises the following steps: adding the thickening and stabilizing mother solution, the O-shaped peregal, the soft water, the ammonia water, the grafted latex and the environment-friendly adhesive into a stirrer for stirring to form a mixed mother solution, and then mixing the mixed mother solution with the latex. The obtained slurry is not smooth and has the phenomenon of turning.
The second method is as follows: the thickening and stabilizing mother solution, the O-shaped peregal, the soft water, the ammonia water and the grafted latex are uniformly stirred by a stirrer, the latex is added, mixed and uniformly stirred, and then the environment-friendly adhesive is added, and uniformly stirred. The obtained slurry is smooth and meets the requirements.
And a third method: adding the grafted latex, the O-shaped peregal, the soft water and the ammonia water into the environment-friendly mixture and the natural latex, and then adding the thickening stable mother solution. The stirring time is long, and the thickening stable mother solution is not easy to disperse.
The test results prove that: the emulsion adhesive composition for the anti-frosting polyester filament yarn shoes, which is manufactured by the method, has poor storage stability and uneven dispersion, is not only easy to generate adhesive layering, but also has extremely unstable adhesive strength and easy to agglomerate and become variable.
The emulsion adhesive composition for the anti-frosting polyester filament yarn shoes, which is manufactured by the second method, has the advantages of high stability, long storage time, stable adhesive property and high adhesive strength.
The emulsion adhesive composition for the anti-frosting polyester filament yarn shoes, which is manufactured by the second method, has the advantages of high stability, long storage time, stable adhesive property and high adhesive strength. However, the preparation and stirring time is long and the energy consumption is high.
This means that the systems must be thoroughly stirred in advance to exert their synergistic effect. Further experiments prove that the stirring time of the mixed mother solution is optimal to be 35-38 minutes.
In conclusion, the slurry preparation process adopts a second method, namely, thickening stable mother liquor, peregal O, soft water, ammonia water and grafted latex are uniformly stirred by a stirrer, latex is added, mixed and uniformly stirred, and then environment-friendly adhesive is added, and the mixture is uniformly stirred.
By adopting the technical scheme, compared with the prior art, the invention has the advantages of low energy consumption, no toxicity, excellent technical performance and simple operation in the manufacturing process, enhances the anti-deformation capability of the adhesive, has better storage stability period, improves the internal performance of the adhesive, and fundamentally meets the requirement on the high adhesive effect of the rubber shoes. The emulsion adhesive composition for the anti-frosting polyester filament shoes adopts the combination of natural emulsion and environment-friendly adhesive as a main material, and ensures higher initial adhesive capacity of the emulsion adhesive composition for the anti-frosting polyester filament shoes because molecules of the emulsion basically keep the original state, and also forms a high-strength unified body with an adhered part due to no change of rubber polymer, so that the adhesive after vulcanization crosslinking has higher final adhesive strength, thereby having low surface adhesive requirement on the adhered part, having low temperature requirement on the adhered part and reducing the requirement of the adhered material on heat preservation performance. The initial adhesive force and affinity of the glued component are improved, and the plastic flow of molecules on the bonding surface of the glued component at the initial stage of high-temperature vulcanization is prevented, so that the glued component and the upper are firmly bonded together by the adhesive, and the three quality problems of lace delamination, base fabric void and outsole elastic edge of the rubber shoes are effectively solved. The emulsion adhesive composition for the anti-frosting polyester filament shoes successfully increases the viscosity of colloid, reduces the free capacity of small molecular weight materials, prevents adhesive components from penetrating through sole cloth, solves the problem of glue penetration quality, and can improve the product percent of pass by more than 2 percent. Because the moisture-absorbing substances are removed, the problem of moisture absorption and whitening of the rubber cement in the storage process of the rubber shoes is solved.
