Description
Technical field
It is more particularly to a kind of to suppress adjuvant and its preparation that zinc burns the present invention relates to a kind of adjuvant and preparation method thereof
Method.
Background technology
In recent years, polyvinyl chloride（PVC）Because its preferably transparency, pliability, compatibility, it is easily processed into type the advantages that
The accreditation of people is obtained, in the commercially available fast development of global plastic products, the dosage of polyvinyl chloride is about in plastics major class
Reach 28%.But PVC because of its structure itself the defects of, less stable during heating, easily decompose and discharge hydrogen chloride gas, solve
Certainly method is to introduce heat stabilizer in PVC process, improves its heat resistance.Conventional heat stabilizer mainly have lead salts,
Metal soap, organic tin, terres rares and calcium/zinc class etc., wherein calcium/zinc class stabilizer have it is nontoxic, environmentally friendly, cheap and
The features such as lubricity is good, there is wide development space.But zinc class stabilizer is in the PVC product later stage because generation is with extremely strong
The de- HCL of catalysis ZnCL2, causing it, resistance to burning property is poor for a long time, and later stage PVC product acutely changes colour, and particularly zinc soap is very easy to
Drastically black, blackspot or whole blackening occurs in product, influences product normal use.
The content of the invention
Phenomenon is burnt in order to suppress the zinc of PVC product, extends product service life, suppresses what zinc burnt the invention provides a kind of
Adjuvant, and describe its preparation method in detail.
A kind of adjuvant for suppressing zinc and burning, is made up of the component of following quality proportioning：
Organic dibasic acid 5-7 parts
Polyalcohol 45-55 parts
Lubricant 9-11 parts
Inorganic assistant 19-21 parts
Magnesium stearate 13-15 parts
The organic dibasic acid is ethanedioic acid or adipic acid.
The polyalcohol is pentaerythrite, D-sorbite or maltitol.
The lubricant is Tissuemat E, OPE or stearic acid monoglyceride.
The inorganic assistant is hydrotalcite, modified zeolite or houghite compound.
Further, the adjuvant of the present invention for suppressing zinc burning is preferably made up of the component of following quality proportioning：
6 parts of adipic acid
Season 50 parts of cyclopentadienyl tetrol
10 parts of Tissuemat E
20 parts of hydrotalcite
14 parts of magnesium stearate
Present invention also offers a kind of method for preparing the suppression zinc and burning adjuvant, comprise the following steps：
S1:It is 5-7 to weigh quality proportioning respectively：In 45-55 organic dibasic acid and polyalcohol input reactor, slowly heating
And carry out reaction and ester type compound is prepared, cooling tabletting is standby；
S2:The ester type compound being prepared in lubricant, inorganic assistant, magnesium stearate and S1 is weighed respectively adds reactor
In, and heat temperature raising is carried out to reactor, each material is continued stirring until into mixed melting, the lubricant, inorganic assistant, tristearin
The ester type compound quality proportioning being prepared in sour magnesium and S1 is 9-11：19-21：13-15：50-62.
Reaction temperature is 50-90 DEG C in the step S1, and preferably esterification reaction temperature is 60 DEG C.
In the step S2 to the mixing time of mixed material between 15-25 minutes, the preferably time is 20 minutes.
Beneficial effects of the present invention：
Adjuvant is burnt by using suppression zinc of the present invention, can effectively delay PVC products zinc to burn the generation of phenomenon, improve
The long-term thermal stability of PVC material, product delay is set to occur or occur without blackspot, beneficial to the service life for extending product.
