Abstract
The invention discloses a kind of low cigarette nonflammable PVC pipe and preparation method thereof, belong to polymer material molding processing technique field.Low cigarette nonflammable PVC pipe of the invention, the raw material composition including following parts by weight: polyvinyl chloride resin 100.0~110.0；Haloflex: 2.0~6.0；ACR-g-VC copolymer resins 2.0~6.0；Stabilizer 4.0~6.0；Calcium carbonate 6.0~15.0；Stearic acid 0.3~0.4；Polyethylene wax 0.4~1.0；Titanium dioxide 1.0~3.0；Fire retardant 4.0~8.0.ACR-g-VC resin and haloflex in the present invention contain chlorine element, smaller on the influence of the flame retardant property of PVC material, and the environmental-protecting performance of PVC pipe has been effectively ensured.
Description
Technical field
The present invention relates to polymer material molding manufacture fields, specifically, be related to a kind of low cigarette nonflammable PVC pipe and
Preparation method.
Background technique
Polyvinyl chloride (PVC) is the high-molecular compound as made of polymerization of vinyl choride monomer, is the biggish general plastic of yield
One of item kind；Because its chemical stability, acid resistance and alkali resistance it is excellent due to there is excellent resistance to corrosion, industry, agriculture
It is widely used in terms of the fields such as industry, municipal works, building water supply and drainage.
Polyvinyl chloride (PVC) plastics are because cheap, and application field is continuously available expansion, therefore people are to PVC plastic
More stringent requirements are proposed for performance.PVC can be decomposed at high temperature releases that CO, HCl etc. be toxic or strong corrosive gas, forms cigarette
Mist will lead to indicator of trapped personnel in fire incident and generate asphyxia, poisoning even death.For there is the PVC pipe of flame-retardancy requirements, often
The composition of halide-containing or antimony oxide and halide is added in formula as fire retardant.Halogenation is used alone
Object, it is fire-retardant, smoke suppressing effect is often not ideal enough；It is combined with antimony oxide, although can be improved flame retardant property, three oxidations two
Antimony waits irritating effect to eye, nose, pharynx, also has stronger irritation to skin, can bring a degree of danger to producers
Evil.In addition, also often relying on the plasticizer components such as dibutyl phthalate, o-phthalic acid dibutyl ester in PVC pipe formula
Guarantee that the processing performance and impact flexibility of material, these plasticizer materials belong to combustible material, the anti-flammability of PVC material can be made
It can decline.
Through retrieving, Chinese patent publication No. CN 105061938 A, publication date 2016.08.31 disclose a kind of PVC resistance
Combustion tubing is made of following raw material by weight: PVC 70-75, ortho-xylene diphenyl ester 3.5-5.5, acrylic acid 2- second
The own ester 7.5-9.5 of base, dormant oil 1.5-3, ethylene glycol ethyl ether 1.3-1.8, silane coupling agent 4.2-6.5, tribasic lead sulfate
7.5-8, dibutyl tin dilaurate 2.4-4.2, first bromobenzene 6-7, iron powder 5-8, fire retardant 4-6；The invention has certain resistance
Fuel efficiency fruit, but smog is larger when high temperature, and smoke suppressing effect is not good enough.
Summary of the invention
1. technical problems to be solved by the inivention
For the technological deficiency that traditional PVC pipe is fire-retardant, smoke suppressing effect is not good enough exists in the prior art, the present invention provides
