Description
Technical field
The invention belongs to technical field of plastic, and in particular to a kind of auxiliary heat stabilizer for polyvinyl chloride and its
Preparation method.
Background technology
Polyvinyl chloride (PVC) is one of 5 kinds of general-purpose plastics, has excellent corrosion resistance and very high mechanical property, and
Cheap, aboundresources, manufacturing process are ripe, therefore its product is widely used in the every field of industrial and agricultural production.But
Due to containing double bond, branched structure and initiator residues etc. in PVC structures, at processing temperatures along with dehydrochlorination reaction
And degrade, discoloration and macromolecules cross-linking also occurs.Therefore, PVC processing must use heat stabilizer.For a long time, for PVC
Heat stabilizer mainly have lead salts, composition metal soaps and organic tin.Wherein, the cadmium soap thermostabilization in lead salt and metallic soap
Property is good, but because of toxicity problem, is of limited application；Organic tin has remarkable a heat endurance and the transparency, but cost compared with
It is high；Most of metal soap is cheap, but stability can not meet application requirement.In order to improve the stable effect of metal soap
Fruit, people introduce miscellaneous auxiliary heat stabilizer wherein, and these compounds are free of metal, when being characterized in being used alone
Heat stabilization very little does not have heat endurance completely, but with metal or organo-tin het stabilizer and used time, between the two
Cooperative effect can be produced, and then effectively improves the thermal stability of system.At present, widely used organic auxiliary heat stabilizer master
There are phosphite ester, epoxide, polyalcohol, nitrogen-containing compound, sulfur-containing compound, beta-diketone compound etc..
PVC material is widely used, and requirement of the people to PVC material quality also more and more higher, particularly super permeable membrane, fresh-keeping
The arts such as film, film, transparent soft board, transparent hose, medical material, medical clear sheet, it is desirable to the whiteness of polyvinyl chloride resin is good,
It is transparent high, but the degree of drawing of pure PVC material, toughness and cold-resistant heat resistance are poor, it is impossible to reach standard, with the addition of various
The performance of the PVC material of auxiliary agent is optimized, but transparency declines.Based on this, the present invention is intended to provide a kind of effectively collaboration
Metal soap improves PVC material heat endurance, and does not influence the auxiliary heat stabilizer of transparency.
Chinese patent CN 104513491A disclose a kind of composition for being used for antishrinking agent in plastic processing, and it is by list
83~88 parts of tristerin and 15~20 parts of pentaerythritol ester and coupling agent or/and chelating agent composition, wherein the season
Doutrate is monopentaerythritol ester, pentaerythritol fatty acid ester or its any combination；Said composition contains coupling agent or/and chelating
Agent, and use the glycerin monostearate of high-purity so that production cost is high, simultaneous reactions process is complicated, in product impurity compared with
It is more, have a strong impact on its resistance to elevated temperatures and transparency.
The content of the invention
In order to solve problems of the prior art (not good enough with high-temperature behavior, to influence PVC material transparency etc.), this hair
A kind of auxiliary heat stabilizer for polyvinyl chloride of bright offer, it is strong with metal soap, organic tin synergy, effectively improves
The heat endurance of PVC material, and the transparency of PVC material is not influenceed.
To solve above technical problem, the present invention adopts the following technical scheme that：
A kind of auxiliary heat stabilizer for polyvinyl chloride, by glycerin monostearate, pentaerythritol stearate and gather
Propylene glycol diglycidylether is prepared, and the glycerin monostearate, pentaerythritol stearate and polypropylene glycol two contract
The weight ratio of water glycerin ether is (2.0~4.0)∶1∶(0.1~0.3).
Preferably, the weight of the glycerin monostearate, pentaerythritol stearate and polypropylene glycol diglycidyl ether
It is (3.0~4.0) to measure ratio∶1∶(0.2~0.3).
Further preferably, the glycerin monostearate, pentaerythritol stearate and polypropylene glycol diglycidyl ether
Weight ratio is 3.6∶1∶0.2。
Preferably, the pentaerythritol stearate is pentaerythritol monostearate and the double stearates of pentaerythrite
Composition.
Further preferably, the weight ratio of the double stearates of the pentaerythritol monostearate and pentaerythrite is (3~4)∶
1。
Preferably, the purity of the glycerin monostearate is 90~95%.
Correspondingly, present invention also offers the preparation method of the above-mentioned auxiliary heat stabilizer for polyvinyl chloride, including with
Lower step：Glycerin monostearate, pentaerythritol stearate and polypropylene glycol diglycidyl ether are taken, mixes, uses three second
Amine regulation system pH value is heated to 80~90 DEG C to 9~10 under stirring, react 1~2h, and reaction terminates, and is sent into spray tower and dusts,
Comminutor is granulated, and tabletting machine, the auxiliary heat stabilizer for polyvinyl chloride is made.
Compared with prior art, the present invention has the advantage that：
(1) present invention be used for polyvinyl chloride auxiliary heat stabilizer using polypropylene glycol diglycidyl ether as crosslinking agent,
It is 9~10 in pH value, at 80~90 DEG C of reaction temperature, glycerin monostearate and pentaerythritol stearate are cross-linked to form polymerization
Thing, course of reaction is simple, and product is more stable, pure.
(2) addition that the present invention is used for the auxiliary heat stabilizer of polyvinyl chloride is the 0.1~1% of PVC weight, itself and gold
It is strong to belong to soaps, the synergy of organic tin, effectively improves the heat endurance of PVC material, and do not influence the transparent of PVC material
Degree, there is anti-the effect of colouring preventing agent at good initial stage, while have good plasticity and lubricity concurrently.
(3) present invention is simple for the preparation method of the auxiliary heat stabilizer of polyvinyl chloride, and power consumption is few, and production cost is low,
It can be applicable.

Antishrinking agent is prepared by Chinese patent CN 104513491A embodiments 3.
Test example one,
PVC material sample is prepared according to formula as below：100 parts of PVC, 0.4 part of stearic acid, 0.5 part of calcium stearate, tristearin
0.4 part of 2.5 parts of sour zinc and auxiliary heat stabilizer.Auxiliary heat stabilizer is respectively the embodiment of the present invention 1~5 and comparative example 1~4
Auxiliary heat stabilizer, difference counter sample 1~5 and comparative sample 1~4.Control sample 1 is set：Do not add auxiliary heat stabilizer；
Control sample 2 is set：Calcium stearate and zinc stearate are not added, only adds the auxiliary heat stabilizer of embodiment 5.
Initial coloring, light transmittance and the heat endurance of above-mentioned PVC material sample are tested, as a result see the table below 1.
Table 1
* the yellow chromaticity measured with Hunter colorimeter；Light transmittance measures according to GB/T2410-2008.
From upper table 1, without the work for improving PVC material heat endurance when auxiliary heat stabilizer of the present invention is used alone
With (control sample 2), but with being cooperateed with after calcium stearate/zinc stearate heat stabilizer compounding, it can significantly extend the coloring of PVC material
Time and melanism time, that is, the heat endurance of PVC material is significantly improved, while do not influence the transparency of PVC material.Sample 1~5
In, the stain resistance at initial stage of sample 5 is optimal, and heat endurance is best, light transmittance highest, therefore embodiment 5 is the optimal of the present invention
Embodiment.
Compared with Example 5, comparative example 1~3 changes partial parameters, the application effect of its obtained auxiliary heat stabilizer
Fruit is deteriorated, not as good as embodiment 1~5.
It the above is only the preferred embodiment of the present invention, it is noted that above-mentioned preferred embodiment is not construed as pair
The limitation of the present invention, protection scope of the present invention should be defined by claim limited range.For the art
For those of ordinary skill, without departing from the spirit and scope of the present invention, some improvements and modifications can also be made, these change
Enter and retouch and also should be regarded as protection scope of the present invention.
