Abstract
The application relates to the field of high polymer material additives, and particularly discloses an anti-aging stabilizer which is prepared from the following raw materials in parts by weight: hydrotalcite 350-370 parts; 190 and 210 parts of zinc stearate; 90-110 parts of barium stearate; 160 portions of antioxidant 140-; 75-85 parts of an anti-ultraviolet agent; 23-27 parts of dipentaerythritol. An anti-aging sunlight fabric comprises the following raw materials: PVC resin, a plasticizer, a filler, an aging-resistant stabilizer, an antioxidant, a processing aid, a lubricant and other aids. The anti-aging stabilizer has better anti-aging performance by compounding dipentaerythritol, zinc stearate and barium stearate. By adding ST-220, the PVC fabric prepared by adding the anti-aging stabilizer is not easy to generate the zinc burning phenomenon. By compounding and using the uracil and the dipentaerythritol, the aging resistance of the aging-resistant stabilizer to the PVC fabric is obviously improved.
Description
Technical Field
The application relates to the field of high polymer materials, in particular to an anti-aging stabilizer and an anti-aging sunlight fabric using the same.
Background
PVC (polyvinyl chloride) is a polymer obtained by polymerizing vinyl chloride monomer in the presence of an initiator such as peroxide or azo compound, or in the presence of light or heat according to a radical polymerization mechanism. Because PVC has the advantages of flame resistance, chemical corrosion resistance, wear resistance, excellent electrical insulation, higher mechanical strength and the like, the PVC has wide application in the aspects of industry, agriculture, buildings, daily necessities, packaging, electric power and the like. PVC resins have been regarded as important in all industrial countries because of their excellent combination properties and relatively low cost.
However, the PVC fabric is easily decomposed under ultraviolet irradiation or in a high-temperature state, so that the PVC fabric has the problems of color change, embrittlement, cracking and the like after being used for a period of time, the physical strength of the PVC fabric is reduced, the service life of the PVC fabric is short, and the use of the PVC fabric is seriously influenced.
Disclosure of Invention
In order to solve the problems that a PVC fabric is easy to age and decompose at high temperature and the service life of the PVC fabric is short, the application provides the aging-resistant stabilizer and the aging-resistant sunlight fabric using the same.
In a first aspect, the present application provides an aging-resistant stabilizer, which adopts the following technical scheme:
an anti-aging stabilizer is prepared from the following raw materials in parts by weight:
hydrotalcite 350-370 parts;
190 and 210 parts of zinc stearate;

Performance test
Referring to examples and comparative examples, a PVC fabric having a thickness of 2mm was prepared, and the PVC fabric was subjected to the following tests:
and (3) high-temperature aging test: after the PVC fabric is aged for 1000h at 80 ℃, the tensile strength and the elongation at break of the PVC fabric before and after aging are tested at 50mm/min according to GB/T528-1998, and the retention rate of the tensile strength after aging and the retention rate of the elongation at break after aging are calculated.
(retention after aging of tensile strength% = tensile strength after aging/tensile strength before aging = 100), (retention after aging of elongation at break% = elongation at break after aging/elongation at break before aging = 100).
The test temperature is 24 +/-0.5 ℃, and the test results are detailed in table 1.
TABLE 1
| StretchingRetention of strength after aging% | Retention after aging of elongation at break% | |
| Example 1 | 87 | 85 |
| Example 2 | 88 | 85 |
| Example 3 | 88 | 87 |
| Example 4 | 90 | 91 |
| Example 5 | 95 | 93 |
| Example 6 | 99 | 97 |
| Example 7 | 99 | 97 |
| Example 8 | 99 | 97 |
| Comparative example 1 | 76 | 69 |
| Comparative example 2 | 78 | 72 |
| Comparative example 3 | 84 | 79 |
| Comparative example 4 | 87 | 80 |
By combining the example 3 and the example 4 and combining the table 1, the urea pyrimidine can slightly inhibit the decomposition of the PVC fabric under thermal aging, improve the aging resistance of the PVC fabric, and enable the PVC fabric to keep good tensile strength and elongation at break after aging.
Combining example 3 and example 5 with table 1, it can be seen that ST-220 can improve the tensile strength and elongation at break of the PVC fabric after aging, because ST-220 can absorb zinc chloride and barium chloride generated by absorbing hydrogen chloride with zinc stearate and barium stearate, and prevent zinc chloride and barium chloride from further catalyzing the aging decomposition of the PVC fabric, and inhibit zinc burning, thereby improving the high temperature aging resistance of the PVC fabric.
By combining the examples 4, 5 and 6 and the table 1, it can be seen that the heat stabilizer prepared by compounding the uracil and the ST-220 remarkably improves the aging resistance of the PVC fabric compared with the heat stabilizer prepared by singly using the heat stabilizer.
By combining the embodiment 6 and the embodiment 7 and combining the table 1, the titanium dioxide has little influence on the high-temperature aging resistance of the PVC fabric, but the titanium dioxide can absorb and reflect ultraviolet light, so that the ultraviolet resistance of the PVC fabric is improved, and the PVC fabric is not easily decomposed in the sun.
By combining the examples 7 and 8 and the table 1, it can be seen that the vinyl chloride-vinyl acetate copolymer resin has a high-temperature shaping and bonding effect when being prepared into a PVC fabric, the compactness of the PVC fabric is improved, and the influence on the aging resistance is small.
By combining the example 3 and the comparative example 1 and combining the table 1, the addition of the dipentaerythritol can obviously improve the aging resistance of the PVC fabric, and the dipentaerythritol, the zinc stearate and the barium stearate have a synergistic effect, so that the dipentaerythritol can absorb hydrogen chloride, can also absorb the zinc chloride and the barium chloride to inhibit zinc burning, and can improve the extreme-ohm gas stability of the PVC fabric, thereby obviously improving the high-temperature resistance and stability of the PVC fabric.
By combining the comparative example 1 and the example 2 and combining the table 1, it can be seen that the effect of the PVC fabric on high temperature and aging resistance can be improved by adding the uracil alone, but the effect is remarkably small when the uracil and the dipentaerythritol are used together, so that the conclusion is drawn that the dipentaerythritol and the uracil have a certain synergistic effect and the high temperature resistance of the PVC fabric can be remarkably improved.
Combining example 3 with comparative example 3 and combining table 1, it can be seen that pentaerythritol has the effect of improving the PVC fabric, but the effect is not as good as dipentaerythritol, because the greater number of hydroxyl groups in dipentaerythritol has better effect of absorbing hydrogen chloride, zinc chloride and barium chloride, and thus the thermal aging resistance of the PVC fabric can be better improved.
When the pentaerythritol and the uracil are compounded for use, the synergistic effect is hardly obvious, as can be seen by combining example 5, comparative example 3, comparative example 4 and table 1.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
