Tension resistant fireproof putty and preparation method thereof

Abstract

The invention discloses a tension resistant fireproof putty and a preparation method thereof. The putty is prepared from, by weight, 18-25 parts of chlorinated paraffin, 10-13 parts of rosin modified phenolic resin, 5-10 parts of butyl rubber, 30-35 parts of diethyl silicone oil, 20-35 parts of a silicone acrylic emulsion, 0.5-3.5 parts of a titanate coupling agent, 1.5-3.5 parts of calcium lignosulfonate, 35-40 parts of pitchstone powder, 10-20 parts of bentonite, 10-20 parts of attapulgite, 0.3-0.5 parts of short carbon fiber and 0.3-0.5 parts of polypropylene filament fiber. The tension resistant fireproof putty has the advantages of high fireproofing performance, strong plasticity, good flexibility, impact resistance, good flue gas tight effect and high fireproofing efficiency, and slightly expands under the action of a high temperature when a fire hazard appears to form a solid fireproof heat insulation layer in order to tightly plug various openings and slits and effectively prevent flame propagation and flue gas propagation.

Description

technical field [0001] The invention relates to the technical field of fire-fighting products, in particular to a stretch-resistant fire-proof blockage and a preparation method thereof. Background technique [0002] Fireproof blockage is used to block various penetrations, such as various openings formed when cables, air pipes, oil pipes, and air pipes pass through walls and floors, and fireproof separation of cable bridges, so as to prevent fire from spreading through these openings and gaps. The current traditional fireproof blockage has poor fire resistance, poor sealing performance, and poor impact resistance. It is easy to burn and crack when a fire occurs, but cannot effectively prevent the spread of flame and smoke. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a stretch-resistant fireproof blockage and its preparation method. The prepared fireproof blockage has high fire resista...
