Content of the invention
The present invention is directed to the deficiencies in the prior art, proposes a kind of preparation method of cpvc impact modifier, can change
Cpvc mobility in process, impact strength is also greatly enhanced, and the weatherability that also mbs does not have.
In order to realize foregoing invention purpose, the present invention provides a kind of technical scheme below: preparation of cpvc impact modifier
Method, chlorinated polyethylene encapsulation acrylic ester compound and molecular weight regulator heat up, acrylic ester compound is in chlorine
Change and polyreaction occurs in polyethylene；Add methyl bright olefin(e) acid formicester, be copolymerized with polymer on chlorinated polyethylene surface
Reaction；The percentage by weight of chlorinated polyethylene, acrylic ester compound and methyl bright olefin(e) acid formicester be 30～50%:65～
45%:5～10%；Molecular weight regulator is the 0-0.8% of acrylic ester compound gross weight.
Further, the atomic number of alkyl carbon of acrylic ester compound is 4～8, or combinations thereof.
Further, in chlorinated polyethylene, chlorinity is 27-37%, preferably 30-35%, more preferably 30-33%.
Further, specific operation process is: water and dispersant stirring and evenly mixing add chlorinated polyethylene, stir,
Add acrylic ester compound and oil-soluble initiator, be warming up to 65-70 DEG C, carry out polyreaction；Add after the completion of polymerization
Methyl bright olefin(e) acid formicester and oil-soluble initiator, 65-70 DEG C is copolymerized, and is warming up to 90 DEG C after the completion of copolymerization, and insulation 1 is little
When more than, be cooled to less than 55 DEG C, discharging.
Further, water addition is 2-3 times of raw material total amount.
Further, dispersant is one or more of gelatin, polyvinyl alcohol, hydroxymethyl cellulose, active calcium phosphate.
Further, initiator is azodiisobutyronitrile, 2,2'-Azobis(2,4-dimethylvaleronitrile), benzoyl peroxide, isopropylbenzene peroxidating
The compositionss of hydrogen, DIBHP and redox system.
Further, acrylic ester compound is butyl acrylate or acrylic acid-2-ethyl caproite.
Further, molecular weight regulator is the alkyl hydrosulfide of c4-c20.
Compared with prior art, the invention has the advantages that be obtained cpvc impact modifier good fluidity, can
Change cpvc mobility in process, impact strength is also greatly enhanced.And also mbs do not have weather-proof
Property.
Specific embodiment
Describe the present invention with reference to embodiment, the description of this part is only exemplary and explanatory, no
Reply protection scope of the present invention has any restriction effect.
A kind of preparation method of cpvc impact modifier, adopts acrylic ester monomer in chlorinated polyethylene (cpe) base
It is polymerized in vivo, the not graft copolymerization on cpe of acrylic ester type compound；Acrylic ester monomer is poly- inside cpe
After the completion of conjunction, add methyl bright olefin(e) acid formicester in cpe surface and acrylic polymer copolymerization, so, hard monomer just
Soft monomer is wrapped in the inside and occurs without tacky phenomenon.Cpe matrix accounts for the 30～50% of raw material weight percentage ratio, acrylic monomerss
Account for raw material weight percentage ratio, methyl bright olefin(e) acid formicester accounts for the 5～10% of raw material weight percentage ratio.Wherein, going back within cpe
Can there is molecular weight regulator, molecular weight regulator is the alkyl hydrosulfide of c4-c20, its total consumption is polymerized monomer gross weight
0-0.8%.
As the cpe of this synthetic material, chlorine content ranges therein between 27-37%, preferably 30-35%, more preferably
30-33%.
The concrete manufacture method of the cpvc impact modifier of this good fluidity is: the first step is to add water and dispersant
Enter in reactor, stir, be subsequently adding cpe, in addition primary first-order equation monomer and oil-soluble initiator after stirring,
Then it is warmed up to 65-70 DEG C of polymerization, polymerization adds secondary monomer and oil-soluble initiator after finishing, in 65-70 DEG C of after polymerization,
After the completion of polymerization, it is warmed up to more than 90 DEG C and cools to 55 DEG C with bottom discharge after being incubated 1 hour.
In above-mentioned detailed process, the addition of water is 2-3 times of the total addition of raw material；Dispersant is gelatin, polyvinyl alcohol
And hydroxymethyl cellulose, active calcium phosphate etc. or these compound；Initiator is azodiisobutyronitrile, azo two different heptan
Nitrile, benzoyl peroxide or isopropyl benzene hydroperoxide or the compositionss of DIBHP and redox system.
Acrylic ester monomer refers to the Arrcostab of the acrylate that carbon number is 4～8, for example butyl acrylate, third
Olefin(e) acid -2- Octyl Nitrite etc., or their mixture.
The vitrification point of the polymer of the esters of acrylic acid of monomer is lower, and the low temperature room temperature impact strength of product is also got over
Good, the carbon number of its acrylic ester monomer is also many as much as possible, and molecular weight is evenly distributed as much as possible, so endothecium structure
It is necessary for being adopted as atomic number alkyl acrylate many as much as possible and molecular weight regulator.
A kind of preparation method of the cpvc impact modifier of excellent processing fluidity, comprises the steps:
1st, add the technique deionized water of formula ratio, the gelatin of formula ratio into 1 cubic metre of reactor, the cpe of formula ratio, stir
Mix and uniformly add the Isooctyl acrylate monomer containing formula ratio azodiisobutyronitrile afterwards, be passed through nitrogen, then begin to warm to 60-70
Degree reaction, surveys conversion ratio and reaches more than 95% after 4 hours.
