Examples of effects
The following table 1 shows the performance analysis results of the adhesion under different conditions of the environment-friendly modified high-molecular hot-melt pressure-sensitive adhesive of examples 1 to 3 and comparative examples 1 to 3.
TABLE 1
From a comparison of the experimental data in table 1, it can be found that the addition of the modified pressure-sensitive particles can significantly improve the adhesion of the material in use under pressure; as can be seen from the comparison of experimental data of examples 1, 2 and 3 and comparative example 1 in Table 1, the large tensile strength under pressure of examples 1, 2 and 3 compared with comparative example 1 indicates that the zinc metalloporphyrin can catalyze the oxidation of diethylbenzene, hydrogen on alpha position of several diethylbenzenes is replaced by oxygen to form peroxy bond to connect adjacent diethylbenzenes, when in use, the pressure is applied at high temperature, so that the peroxide bond of the peroxide-connected diethylbenzene in the modified pressure-sensitive particles is uniformly cracked to form two oxygen free radicals, and the gaps among the branch deformation molecules are enlarged under pressure to release oxygen radicals, the oxygen radicals with high activity compete for hydrogen on carbon chains in the asphalt to form carbon radicals, the carbon radicals are connected with other carbon chains to form carbon radicals with larger molecular weight so as to initiate crosslinking, and are wound in a crossed manner, so that the pressurizing cohesiveness of the environment-friendly modified high-molecular hot-melt pressure-sensitive adhesive is improved; the experimental data comparison of examples 1, 2 and 3 with comparative example 2 shows that the tensile strength under pressure is higher than that under pressure and the tensile strength under no pressure is lower than that under pressure of comparative example 2 in examples 1, 2 and 3, which indicates that after the reaction and the end capping with dimethyloldimethoxysilane, the branches at the outer side grow and are tighter, and the peroxidized diethylbenzene sealed in the modified pressure-sensitive particles is less prone to loss, so that the stability of the environment-friendly modified high-molecular hot-melt pressure-sensitive adhesive under no pressure is improved, and meanwhile, the growing branches are provided with silicon hydroxyl groups, and a silicon-oxygen network is formed among the branches, so that the pressure adhesion of the environment-friendly modified high-molecular hot-melt pressure-sensitive adhesive is improved.
