Preferably, the protrusion is made of hydro-expansive rubber.
A kind of preparation process of bridge expanssion joint waterstop, includes the following steps:
The selection of S1, raw material: including being formed by the raw material of following parts by weight: 5,601 100 parts of EPDM, tasteless DCP 10
Part, 40 parts of N550,20 parts of white carbon black, 60 parts of plasticizer, R-503 parts, 0.8 part of S；
The preparation of S2, rubber fastening band: EPDM 5601 is kneaded on a mill and packet roller, and temperature is controlled in 45-55
DEG C, carbon black, plasticizer, N550 and R-50 is added, vulcanizing agent tasteless DCP and S, thin logical 3- are sequentially added after being cooled to 20 DEG C
It 5 times, is uniformly mixed, bottom sheet, molding is rubber fastening band finished product.
Preferably, in the step S2 curing temperature of open mill be 170 DEG C, vulcanization time 15min, pressure 9-
11MPa。
Preferably, in the step S2 open mill model XK-160.
Technical effect and advantage of the invention: the preparation process of the bridge expanssion joint Water stop structure and waterstop, no
Enter inside expansion joint simply against mud, and waterstop play it is normal anti-in the case of the bridge expanssion joint mutation changing of the relative positions
Water effect, product material reach design requirement performance indicator, have good anti-aging property and corrosion resistance, while meeting bridge
The requirement of the long-time service of beam expansion joint environment, rubber strip waterstop are answered using generating enough contacts on waterproof working face
Power achievees the purpose that waterproof, and detachable, maintenance or replacement in validity period, ensure that product structure meets engineering and uses need
It asks, preparation process is simple.
