Abstract

The invention discloses non-curable waterborne acrylic resin flame-retardant embedded rubber, which is prepared from the following components by weight percent: 40-50% of waterborne acrylic resin, 30-40% of epoxy resin, 8-12% of a flame retardant, 2-4% of a dispersing aid, 0.5-2.5% of a defoaming agent and 5-12% of chlorinated rubber powder. The invention also discloses a preparation method of thenon-curable waterborne acrylic resin flame-retardant embedded rubber. The embedded rubber obtained by using the preparation method can be constructed at the room temperature, is not only convenient and simple in construction, but is also energy-saving and environmentally-friendly, has excellent creep resistance, fireproof performance and self-repairing capability, is free from pollution, can effectively block the leakage of water from cracks, and can be widely applied to construction of expansion joints and deformation joints of underground engineering.

Description

technical field [0001] The invention relates to a waterproof material for joints of underground infrastructure such as tunnels and comprehensive pipe galleries, in particular to a non-curing water-based acrylic resin flame-retardant embedded glue and a preparation method thereof, belonging to the technical field of chemical products. Background technique [0002] The rapid development of cities has brought continuous transformation and expansion of large cities and megacities. The scale and structure of the city are undergoing major changes, and a large number of tunnels and comprehensive utility corridors have emerged with the expansion of the city. Since tunnels and pipe galleries are buried underground and are in the groundwater environment all year round, their waterproof effect directly affects the function of the tunnel and the success or failure of the entire project. [0003] Due to construction factors, uneven foundation settlement factors, temperature deformation ...
