The preparation method of above-mentioned a kind of rubber water-proof, is characterized in that carrying out as follows:
(1) mass fraction of each raw material is: 100 parts, styrene-butadiene rubber(SBR), composite reinforcing agent 40 ~ 80 parts, vulcanizing agent 2 ~ 5 parts, vulcanization accelerator 1 ~ 3 part;
(2) take raw material according to the above ratio, the banburying in Banbury mixer by styrene-butadiene rubber(SBR) and composite reinforcing agent, keep temperature to be 140 ± 5 DEG C, batch mixing 5-15 minute;
(3) then in Banbury mixer, add vulcanizing agent, vulcanization accelerator successively, keep temperature to be 140 ± 5, batch mixing 5 ~ 10 minutes, then discharging, is pressed into thin slice through mill;
(4) thin slice is put into mould, in vulcanizer, carry out sulfuration, curing temperature is 160 ~ 180 DEG C, and sulfide stress is 10 ~ 15MPa, and curing time is 5 ~ 20 minutes, and sulfuration terminates to be cooled to room temperature, takes out cross-linked rubber, obtained rubber fastening band.
Beneficial effect of the present invention is as follows:
1. the present invention is by being undertaken mixing by composite reinforcing agent and styrene-butadiene rubber(SBR), forms nano composite structure, to improve the stopping property of styrene-butadiene rubber(SBR), thus effectively improves the stagnant water effect of waterstop.
2. the present invention selects composite reinforcing agent and styrene-butadiene rubber(SBR) blending and modifying, thus makes polymkeric substance have high strength and rubber.
