Problems solved by technology

At present, in the prior art, the fire-blocking module is used to seal the hole and the fire-blocking of the cable trench mostly has the following problems: First, the water resistance is poor
Although some plugged holes or fire-blocking partitions using fire-blocking modules have been finished, water vapor can still enter the finish layer, making the soaked fire-blocking modules swell and loose, and peeling and grain loss occur; second, fire-resistant poor performance
Since the fire retardant module uses a large number of polymer adhesives, even if the flame retardant is added, there is still a certain combustion performance
Third, the processing technology is complex
Due to the extensive use of polymer adhesives, the drying time of the fire retardant module is prolonged. In order to shorten the drying time, heating and baking are often used, which wastes energy and increases the amount of labor.

Abstract

The invention discloses a novel composite fire retardant module and a preparation method thereof. The novel composite fire retardant module has good fire retardance and water resistance and is also simple in processing technology, convenient in construction and nontoxic and nonharmful to the environment.

Description

technical field [0001] The invention relates to a fire-blocking module and a preparation method thereof, in particular to a novel composite fire-blocking module and a preparation method thereof, and belongs to the technical field of fire-proof sealing materials. Background technique [0002] The fire-blocking module is a kind of fire-proof sealing material, which is mainly used for the sealing of holes such as wires and cables passing through walls and floors, and the use of cable trenches as fire-blocking partitions. The fire retardant module can effectively prevent wires and cables from spreading to adjacent spaces through holes due to heat and fire, endangering connected electrical equipment and causing greater losses. At present, in the prior art, the fire-blocking module is used to seal the hole and the fire-blocking of the cable trench mostly has the following problems: first, the water resistance is poor. Although some plugged holes or fire-blocking partitions using ...
