Description
Technical field
The present invention relates to chliorinated polyvinyl chloride (CPVC) profiles.
Background technique
The features such as CPVC is a kind of new type chemical material, corrosion-resistant with heatproof, and anti-flammability is high, and mechanical property is good.Together
When, certain characteristics due to CPVC due to inheriting PVC also possess a characteristics of Other Engineering plastics are not had,
That is exactly good dimensional stability, and so-called dimensional stability refers under high temperature and cryogenic conditions, the variation width of size
It spends smaller, it is relatively low to be embodied in thermal expansion coefficient, therefore be highly suitable for that size distortion rate is required to compare
Harsh field.CPVC also has good heat resistance concurrently simultaneously, and heat distortion temperature can achieve 90 DEG C or so, dimension card softening
Point reach 105 DEG C or more, this be PVC institute it is inaccessiable, even therefore under the weather condition of thermal extremes, the material is still
So possess good dimensional stability and lower deformation rate, can be obtained in terms of automobile-used hard material more better than PVC
Using.
Currently, CPVC product also obtains relatively broad application in terms of passenger car, main application form is decoration
Item, sealing strip skeleton etc..Due to national requirements for environmental protection, requirement of the present automobile interior decoration for carbon volatile quantity is higher and higher.Especially
It is superior automobile, the requirement to total carbon volatile quantity is even more stringent.In order to reduce carbon volatile quantity, best way is exactly to reduce plastics
The dosage of middle liquid.Use Pickering agent and plasticizer.But all contain lead salt in general Pickering agent, or same
Environmental protection standard is not met.The Pickering agent of Special Category must be used.Therefore, developing one kind has Ultra-low carbon volatile quantity,
Without noxious material, other physical properties are all up to standard, and the automobile-used Profile Formulation of the CPVC that can smoothly process just becomes and works as
It is engaged in anxious.
Summary of the invention
The purpose of the present invention is disclosing a kind of ultralow total carbon volatilization chliorinated polyvinyl chloride profile and its application, to meet correlation
The needs of field application.
The ultralow total carbon volatilization chliorinated polyvinyl chloride profile, the boiling containing the surface grafting as auxiliary stabilizer
Stone, the zeolite of the surface grafting are that the surface grafting of the zeolite has stearic acid, and zeolite can be used and stearic acid carries out physics
Be blended, be prepared, zeolite mix with stearic acid, be heated to stearic acid and melt, it is then cooling, zeolite with it is stearic
Weight ratio is 1: 5~10；
The surface grafting of the zeolite has stearic zeolite, it is also assumed that be it is a kind of using stearic acid to zeolite table
The zeolite that face is modified；
Using Shang Qi group standard SMTC_5_400_009 and national standard GB T 27630-2011 " riding in-car air quality
Guide " as defined in method, to the automobile-used profile of the described ultralow total carbon volatilization chliorinated polyvinyl chloride profile, carry out total carbon volatilize into
Row detection, total carbon volatilization is 90 (μ gC/g) or lower, and preferably total carbon volatile quantity is less than 6.01 (μ gC/g), most preferably
, total carbon volatile quantity is 3.5~6.01 (μ gC/g)；
Preferably, ultralow total carbon volatilization chliorinated polyvinyl chloride profile, the component including following parts by weight:
The main stabilizer is organic tin stabilizer, such as the product that Rhom and Hass's trade mark is TM181；
The impact modifier is MBS, and its chemical name is methyl methacrylate, butadiene, styrene terpolymers
The product that the Japanese Zhong Yuan company trade mark is MBS564 can be used in object；
The lubricant is high-melting-point PE wax and OPE wax, and fusing point is 80~105 DEG C；
The filler is powdered whiting；
The titanium dioxide is rutile type titanium white or anatase thpe white powder；
The preparation method of ultralow total carbon volatilization chliorinated polyvinyl chloride profile of the invention, includes the following steps:
CPVC mixing specific the preparation method is as follows: modified zeolite is added in chlorinated polyvinyl chloride resin, and in addition to
Other auxiliary agents outside impact modifier are mixed in the mixed machine of heat, and temperature rises to 90 DEG C or so, and impact modifier is added and is blended
It to after 130 DEG C, is put into cooling mixing machine and is cooled down, be cooled to 35 DEG C hereinafter, discharging, later, is squeezed on extruder
Out, it can be obtained the ultralow total carbon volatilization chliorinated polyvinyl chloride profile.
Ultralow total carbon of the present invention volatilizees chliorinated polyvinyl chloride profile, total carbon volatile quantity less than 6.01 (μ gC/g), and
Other physical properties are up to state standards, and can satisfy the needs of passenger car profile, can be used for preparing ornamental strip and sealing strip
The accessories such as skeleton.
Ultralow total carbon volatilization chliorinated polyvinyl chloride profile of the invention uses the boiling for being free of lead salt by adjusting stabilizer
Masonry is heat stabilizer, reduces carbon volatility.Meanwhile lubrication amount is improved, keep the smooth extrusion of material itself.Wherein, this boiling
Stone will carry out mixed grafting with stearic acid, can preferably be combined with CPVC resin, not generate too big shadow to other performances of material
It rings.Cost is greatly lowered simultaneously.
Specific embodiment
Examples 1 to 9 is parts by weight
In embodiment 1-9:
Main stabilizer is organic tin stabilizer, uses Rhom and Hass's trade mark for the product of TM181；
The impact modifier is MBS, and its chemical name is methyl methacrylate, butadiene, styrene terpolymers
The product that the Japanese Zhong Yuan company trade mark is MBS564 can be used in object；
The auxiliary stabilizer is the stearic zeolite of surface grafting, and zeolite can be used and stearic acid carries out physics and is total to
It is mixed, be prepared, in Examples 1 to 4, zeolite and stearic weight ratio are 1: 5, remaining embodiment be zeolite with it is stearic
Weight ratio is 1: 10；
The lubricant is fusing point: the PE wax that embodiment 1 is 80 DEG C, and embodiment 2 is 95 DEG C of OPE waxes, remaining is 105 DEG C
OPE wax；
The impact modifier is MBS；
The filler is powdered whiting；
Titanium dioxide is used for rutile-type with brightening.
The preparation method is as follows:
CPVC mixing specific the preparation method is as follows: modified zeolite is added in chlorinated polyvinyl chloride resin, and in addition to
Other auxiliary agents outside impact modifier are mixed in the mixed machine of heat, and temperature rises to 90 DEG C or so, and impact modifier is added and is blended
It to after 130 DEG C, is put into cooling mixing machine and is cooled down, be cooled to 35 DEG C hereinafter, discharging.
Later, it is squeezed out on extruder, obtains squeezing out profile.Total carbon volatilization is carried out to the automobile-used profile after extrusion to survey
Examination.Specific test method and performance are " riding referring to Shang Qi group standard SMTC_5_400_009 and national standard GB T 27630-2011
In-car air quality guide " as defined in method.
According to data, the total carbon volatilization of in-car decorations needs to can be only achieved enterprise's mark of Shang Qi group lower than 90 (μ gC/g)
It is quasi-.The number of test result, total carbon volatile quantity is only related with organic Theil indices.Due to using pure Pickering agent, reduce
The dosage of organic tin stabilizer, the total carbon volatile quantity of embodiment 1-9 entirely reach Shang Qi conglomerate standard, and have very big be full of
It is remaining.
