The fields such as vehicle, household electrical appliance, computer and communication apparatus, various electronic instruments, currently still with soft PVC materials
Based on.Soft polyvinyl chloride be made into dedicated automotive wire bundle together with connection plug-in unit again after metallic conductor coextru-lamination and pacify
Dress uses.However, using polyvinyl chloride as the automotive wire bundle of base material, still there are many defects in use at present.Due to polyvinyl chloride wire
A large amount of uses of the lower-molecular substances such as a large amount of plasticizer, stabilizer and lubricant, especially plasticizer are added in beam material,
Make in the automotive wire bundle processed containing unpleasant, harmful air accumulation in car body.In recent years, with consumer
The raising of health perception and environmental consciousness is growing more intense to the reaction of this problem.Low volatilization, low smell, nothing are developed as early as possible
Harmless, the environmentally protective PVC automotive wire bundle CABLE MATERIALSs of poison become the current industry project for being badly in need of solving.
Solve the problems, such as that the smell of PVC formulas is currently the hot fields of PVC automobile cable material research, a kind of existing low gas
Taste, low volatilization environment-friendly type PVC cable material, this method is using PVCSG-4 types resin and hexamethylene 1.2- dioctyl phthalate dinonyl esters
It is blended with acetyl tributyl citrate fourth monooctyl ester, addition calcium zinc stabilizer, aluminium hydroxide, zinc borate and antioxidant 1010 etc. make low gas
Taste CABLE MATERIALS；Through Volkswagen《The component odor detection of 3900 inner space of vehicle of PV》Method carries out odor detection, passes through
2.5 grade（Index request is less than 4.0 grades）.Also there are a kind of the cold-resistant of existing nonirritant taste, oil resistant, flame-proof PVC cable
The formula of material, this method selects ethylenecarbon monoxide-acetate ethylene copolymer, nitrile rubber as the oil resistant being formulated, resisting cold changes
Property agent, makes plasticizer consumption be reduced to 15-20 parts.Also a kind of low smell PVC trunking sizing materials, the primary plasticizer used for
Trioctyl trimellitate (TOTM) class, extender plasticizer are p-phthalic acid's dioctyl ester and epoxidized soybean oil.A kind of existing low volatilization
Eco PVC cable compounds composite formula, this method use hexamethylene 1.2- dioctyl phthalate dinonyl esters and polyester plasticizer
GX-68, which is used in combination, is used as primary plasticizer.Antimony oxide, zinc borate and aluminium hydroxide are as fire retardant.A kind of existing use
In the PVC cable material formula and preparation method thereof of automobile, this method uses the degree of polymerization for the Corvic of SG-4 types, inclined benzene
It is extender plasticizer that three sour three monooctyl esters, which are primary plasticizer, vinyl propionate and octyl epoxy stearate, use Rosa Damascana for except
Taste agent.It is found with method analysis by being formulated above, eliminate the smell in PVC cable material formula, common method is to select resistance to height
It is warm, it is low volatilization, low smell type plasticizer, or using aggretion type high molecular weight plasticizer replace part monomerics
To reduce monomerics dosage, or using the reduction PVC cable material such as addition type molecular sieve, eliminating smell agent, mask agent
In penetrating odor, all achieve and good de-taste effect.
Automotive trim plastic material evaluation in, select hot environment under have it is low volatilization, low odor effect, to human body without
There is specific statutory standard in each state of material of injury, such as European Union's REACH environmental regulations, EU Council 2007/47/EC
Number instruction, the food contact approval of Japanese health PVC associations, Volkswagen《3900 inner space of vehicle of PV
Component odor detection》Deng the present invention has references to Shanghai SGS certification authorities to plastic material odor detection method：VS-01.00-T-
14004-A1-2004, smell rating scale as defined in this method is as follows, and sample is closed in 65 DEG C of next constant volume devices, and to place 24 small
When olfactometry, imperceptible is 1 grade；It is discernable, but non interference smell is 2 grades；Obviously discover, but non interference smell is
3 grades；It is 4 grades to have interference smell；It is 5 grades to have strong interference smell；It is 6 grades that smell can not be endured by, which having,.The present invention is trying
Testing middle discovery, its oder levels can reach 2.5-3 using the PVC automotive wire bundles CABLE MATERIALS of aforementioned invention formula development
Between grade, oder levels reach that 2.5 grades of formulas below designs are extremely difficult, and basic reason is the low molecular weight increasing in formula
Modeling agent is not fully substituted, and reduces PVC cable material moderate stimulation gas using molecular sieve, eliminating smell agent, mask agent of addition type etc.
The effect of taste is limited.
