Abstract
The invention discloses a kind of PP R special material for tube formulas with high flame resistance, formula include PP R monomers, fire retardant, lubricant, dispersant, Antidrip agent, antioxidant, light stabilizer, and the parts by weight of each component are specially in the formula：20~25 parts of 50~65 parts of PP R, fire retardant PDBPP, 5~8 parts of activated carbon, 8~12 parts of stearic acid, 5~10 parts of dispersant ethylene group bis-stearamides, pure 5~15 parts of powder type polytetrafluoroethylene (PTFE), 5~8 parts of calcium stearate, 1~5 part of antioxidant, 0.3~1 part of light stabilizer.The present invention provides a kind of PP R special material for tube formulas with high flame resistance, by the way that the auxiliary agents such as fire retardant PDBPP, lubricant stearic acid, dispersant ethylene group bis-stearamides, Antidrip agent polytetrafluoroethylene (PTFE) are added in PP R, to improve the anti-flammability of PP R tubing, the requirement of construction material B1 flame retardant ratings is reached.
Description
Technical field
The present invention relates to PP-R pipe technical field, especially a kind of PP-R pipe PP Pipe Compound with high flame resistance is matched
Side.
Background technology
PP-R also known as three type PA tubes, atactic copolymerized polypropene become pipe using atactic copolymerized polypropene is extrudable
Material can also be molded as pipe fitting.Its toughness of products is good, and shock resistance is strong, and processing performance is excellent, reduces hot melt jointing temp,
It is essentially identical with homopolymer in terms of chemical stability, water vapour isolation performance simultaneously.PP-R can be widely applied to squeeze out, blow
Modeling, injection molding, film and sheet extrusion manufacture field, can be used as packaging material for food, medical packaging material and common consumer product.
Currently, the fire protection pipeline in building uses coating steel pipe, but coating steel pipe gets rusty easily, corrodes, and leads to pipeline system
System leak, increases the cost safeguarded and replaced, and coating steel pipe weight is big, transport and installation complexity.PP-R pipe and tradition
Coating steel pipe compare, have that energy-saving and environmental protection, light high-strength, corrosion-resistant, inner wall smooth non-scaling, installation and repair are easy, make
The advantages that with long lifespan, is widely used in the fields such as building water supply and drainage, town and country plumbing, city gas.However, giving in building
Water piping system belongs to inflammable raw material, easy tos produce fire using common PP-R materials, significantly limits PP-R pipes
The use of material.
Invention content
In order to overcome the inflammable defect of PP-R pipe existing in the prior art, the flame retardant rating of PP-R pipe, this hair are improved
It is bright that a kind of PP-R pipe formula of special material with high flame resistance is provided, by adding fire retardant PDBPP, lubrication in PP-R
The auxiliary agents such as agent stearic acid, dispersant ethylene group bis-stearamides, Antidrip agent polytetrafluoroethylene (PTFE), improve the fire-retardant of PP-R pipe
Property, to reach the requirement of construction material B1 flame retardant ratings, and there is obdurability, high stability and corrosion resistance.
The technical solution adopted by the present invention to solve the technical problems is：A kind of PP-R pipe with high flame resistance is special
With material formula, including PP-R monomers, fire retardant, lubricant, dispersant, Antidrip agent, antioxidant, light stabilizer, each component
Parts by weight are：
A kind of above-mentioned PP-R pipe formula of special material with high flame resistance, the dispersant are that ethylene group is double hard
Acyl amine.
A kind of above-mentioned PP-R pipe formula of special material with high flame resistance, the Antidrip agent polytetrafluoroethylene (PTFE) are
Pure powder type.
A kind of above-mentioned PP-R pipe formula of special material with high flame resistance, the antioxidant are antioxidant 1010 four
[3- (3,5- di-tert-butyl-hydroxy phenyls) propionic acid] 10176 β of pentaerythritol resin or antioxidant-(3,5- di-t-butyl -4- hydroxyls
Base phenyl) propionic acid octadecanol fat.
A kind of above-mentioned PP-R pipe formula of special material with high flame resistance, the light stabilizer are ultraviolet radiation absorption
Agent UV-531 2-hydroxy-4-n-octoxybenzophenones or light stabilizer AM-101 2,2'- thiobis (4- t-octyl phenol oxygen
Base) nickel.
The invention has the advantages that a kind of PP-R pipe formula of special material with high flame resistance of the present invention, by PP-
R is by increasing the auxiliary agents such as fire retardant, lubricant, dispersant, Antidrip agent, to reach wanting for construction material B1 flame retardant ratings
It asks, by the tubing of this formula production, not only flame retardant property is good, light weight, corrosion-resistant, and material has obdurability and height steady
It is qualitative, it may be used at fire resistance rating and requires high place, fire-fighting pipe-line system and automatic sprinkler fire-extinguishing system.
