Flame-retardant smoke-suppression pipe material

Abstract

The application provides a flame-retardant smoke-suppression pipe material. The pipe material is prepared from, by mass, 80-100 parts of polyvinyl chloride, 0.5-2 parts of lubricant, 5-15 parts of stabilizer and 5-25 parts of flame retardant and smoke suppressant. The flame retardant and smoke suppressant includes 0.5-4 parts of palygorskite, 1-5 parts of a silane coupling agent modified Mg(OH)2,2-5.5 parts of a silane coupling agent modified nano montmorillonite and 1.5-5.5 parts of a titanate coupling agent modified Nano-SiO2; wherein the silane coupling agent accounts for 2.5% by mass of Mg (OH)2, the silane coupling agent accounts for 2.5% by mass of nano montmorillonite and the titanate coupling agent accounts for 2% by mass of nano-SiO2. Compared with existing flame retardants and anti smoke additives, the flame-retardant material is modified by organic modifier, the effect of flame retardants and smoke suppressants on mechanical properties of water pipe materials is reduced, atthe same time, synergistic flame retardancy among flame-retardant materials, makes the water pipe material have good flame retardancy and smoke suppression performance. Provided is a water pipe material with good flame retardant and smoke suppressing performance without reducing the mechanical properties of the pipe material.

Description

technical field [0001] The invention relates to the technical field of water pipe materials, in particular to a flame-retardant and smoke-suppressing water pipe material. Background technique [0002] Polyvinyl chloride (PVC) is the most widely used general-purpose plastic in the world. Due to the advantages of light weight, smooth surface, small resistance, large drainage, convenient installation, and low price, PVC drainage pipes are widely used in indoor drainage construction of residential buildings and public buildings. [0003] Although PVC is a self-extinguishing material, when a fire occurs, PVC will produce a large amount of black smoke and toxic gases, such as carbon monoxide, benzene aromatic compounds, etc., which will cause harm to the human body and even cause death by suffocation. Therefore, people have higher and higher requirements for the flame retardant and smoke suppression performance of PVC water pipes used in buildings. The usual method is to add flam...
