Abstract
The invention relates to a rubber adhesive. The rubber adhesive comprises, by weight, 62-66 parts of hexamethoxymethylmelamine and 34-38 parts of white carbon black; the content of silica in the white carbon black is not lower than 90%, and the heating decrement is not greater than 4.0%. A preparation method of the rubber adhesive comprises the following steps: preparing above raw materials according to corresponding weight parts; heating hexamethoxymethylmelamine to 80-100DEG C, weighing, adding the white carbon black and hexamethoxymethylmelamine into a vacuum cone mixer, and stirring at a rotating speed of the vacuum cone mixer of 8-15r/min under a stirring bin pressure of 0.1-0.2MPa for 20min; and discharging parts of the obtained material from the bottom of the vacuum cone mixer, pouring the discharged material into the vacuum cone mixer from the top, and stirring for 10-30min until complete uniform mixing. The preparation method of the rubber adhesive improves the adhesion performance of the rubber adhesive. The adhesion performance of the rubber adhesive is high.

The object of the invention is to be achieved through the following technical solutions:
A kind of rubber adhesive, by weight, comprises following starting material: HMMM 62 ~ 66 parts; White carbon black 34 ~ 38 parts; Described white carbon black requires dioxide-containing silica >=90%, weight loss on heating≤4.0%.
Further, described HMMM reacts obtained by six hydrocarbon methyl melamines and carbinol condensation.
This rubber adhesive, its bond properties is higher.
There is provided a kind of preparation method of rubber adhesive, it can improve the bond properties of rubber adhesive simultaneously.
Prepare the preparation method of above-mentioned rubber adhesive, comprise following processing step:
A, by weight ratio above-mentioned each raw material;
B, heat described HMMM to 80-100 DEG C and weigh, white carbon black and described HMMM are added in vacuum conical mixing machine, described vacuum conical mixing machine rotating speed is 8 ~ 15r/min, and stir storehouse pressure is 0.1MPa ~ 0.2MPa;
C, stirring, after 20 minutes, are poured into from top again from the bottom releasing portion sub-material of vacuum conical mixing machine, again stirring 10-30 minute to mixing completely, completing preparation.
The preparation method of this rubber adhesive, adopts vacuum conical mixing machine, and optimizes processing parameter simultaneously, determines best parameter matching, thus improves the bond properties of rubber adhesive.
Further, described HMMM reacts obtained by six hydrocarbon methyl melamines and carbinol condensation.
Rubber adhesive of the present invention, by weight, comprises following starting material: HMMM 62 ~ 66 parts; White carbon black 34 ~ 38 parts; Described white carbon black requires dioxide-containing silica >=90%, weight loss on heating≤4.0%.Prepare the preparation method of above-mentioned rubber adhesive, comprise following processing step: a, by weight ratio above-mentioned each raw material; B, heat described HMMM to 80-100 DEG C and weigh, white carbon black and described HMMM are added in vacuum conical mixing machine, described vacuum conical mixing machine rotating speed is 8 ~ 15r/min, and stir storehouse pressure is 0.1MPa ~ 0.2MPa; C, stirring, after 20 minutes, are poured into from top again from the bottom releasing portion sub-material of vacuum conical mixing machine, again stirring 10-30 minute to mixing completely, completing preparation.The preparation method of this rubber adhesive, adopts vacuum conical mixing machine, and optimizes processing parameter simultaneously, determines best parameter matching, thus improves the bond properties of rubber adhesive.The bond properties of this rubber adhesive is higher.
