Abstract
The invention discloses a sealant with a silicone single-component structure and a preparation method thereof, solving the problems that seal property is poor and the like in the prior art. In the preparation method, more than 30 raw materials are used, such as room temperature vulcanization methyl silicon rubber, dimethicone, 107 silicon rubber, gas phase silicon dioxide and the like, thus the capabilities of ultraviolet rays resistance, ageing tolerance and strong acid and base resistance of a product are improved, so that the defects of the product in the aspects are overcome; and the sealant in the invention is rapid in solidification, wide in adaptive range and high in strength after solidification, and the bearing tension of the sealant is twice as large as that of common sealant. Especially, the sealant in the invention still can maintain good property even if being soaked in water for a long term, and has good social and economic benefits.

20 parts of 2 parts of nano-calcium carbonates of 15 parts of aerosils of 107 silicon rubber
1 part of 0.7 part of titanium dioxide of the white carbon black of gas phase 3 parts of precipitations nanometer CC powder
The second raw material group:
The 3rd raw material group:
The 4th raw material group:
For achieving the above object, the manufacture method of silicone single-component structure sealant of the present invention is:
Vacuumized 1 hour after mediating evenly in the raw material adding vacuum kneader with the first above-mentioned raw material group, vacuum tightness is 0.06-0.09Mpa;
The raw material that adds the second above-mentioned raw material group again, be warmed to the 140-165 degree after, mediated and vacuumize 3.5-4 hour; Kneaded raw material is ground, become base-material;
Under the room temperature base-material is joined in the high speed dispersor, add the 3rd above-mentioned raw material group raw material simultaneously, disperse half an hour; Then, add the 4th above-mentioned raw material group raw material again, continue to disperse 45-65 minute, make silicone single-component structure sealant.
Adopt the seal gum of the present invention and the manufacture method thereof of above-mentioned prescription, have following advantage:
Improved the UV resistant, ageing-resistant of product, the strong acid-base resistance ability has remedied its defective that exists in these areas; Quick solidifying, applied widely, the cured strength height, comparable general carrying pulling force is strong one times.Particularly, long period of soaking still can keep good performance in water.
