Abstract

The invention discloses a flame-retardant polyolefin resin composition and a preparation method thereof, and a flame-retardant tubular product prepared from the flame-retardant polyolefin resin composition. The flame-retardant polyolefin resin composition disclosed by the invention comprises the following components in parts by weight: 100 parts of polyolefin resin, 30-85 parts of antimony bromine composite flame retardants, 2-20 parts of resin modifiers and 0.3-1.5 parts of processing agents. The tubular product prepared from the flame-retardant polyolefin resin composition disclosed by the invention has the advantages of being high in heat resistance (the vicat softening temperature of the material can be up to over 140 DEG C), high in flame retardant property (the oxygen index is greater than over 32), good in hot water resistance, low temperature resistance and long-term static hydraulic performance, long in service life, free of scaling and the like, the vertical combustion can be up to V0 grade, the smoke density SDR is smaller than 75, the damaged tubular product caused by external force can be connected in a hot melting manner, and the flame-retardant tubular product can be applied to products such as a central air conditioning pipe system, industrial water supply and drainage pipelines and the like.

Description

technical field [0001] The invention belongs to the technical field of fire protection, and in particular relates to a flame-retardant polyolefin resin composition, a preparation method thereof, and a flame-retardant pipe. Background technique [0002] Due to the improvement of the quality of life of modern people, the requirements for their living environment are also increasing day by day. The living environment that is most often close to it is the office and your own home. There are decorations and landscaping in offices and homes, and central air-conditioning pipes, water supply and drainage pipes, etc. are installed behind these decorations and landscaping. The rules and types of these central air-conditioning pipes and water supply and drainage pipes are very diverse, including metal pipes, non-metal pipes and composite pipes. However, the disadvantages of metal pipes such as easy rust and corrosion, inconvenient installation, and high cost are not popular. At pres...
