For example 1, example 2, example 3, comparative example 1, comparative example 2, comparative example 3, comparative example 4, 6 parts of each sample, of which 3 parts were subjected to an impact strength test using national standard GBT9330.2-2008, and 3 parts were subjected to an aging resistance test using ASTM D4329-05 by accelerated aging, the results were as follows,

watch 1

The thermal stability performance test was performed on 3 samples of each of examples 1, 2, 3, and 4, using the method of GB/T13464-2008, and the results were as follows,

Data and analysis

Comparative example 1 the retention rate of impact strength after aging and the thermal stability temperature are higher than those of examples 1, 2 and 3, because no phosphorus trichloride is added in comparative example 1, the product of the invention is used for the outer wrapping material of the optical cable and needs better flexibility, so a certain amount of plasticizer needs to be added, the invention selects benzoic acid as the plasticizer, the benzoic acid and the phthalic acid C7-C9 alcohol are mixed, dioctyl phthalate plays a role together, the flexibility of the product is increased, and the phosphorus trichloride is also added, can be combined with part of benzoic acid to generate benzoyl chloride, and the benzoyl chloride is an excellent ultraviolet absorbent, can enhance the ultraviolet resistance of the product, and can enhance the stability of the product under strong light.

The impact strength retention rate, the impact strength retention rate after aging and the thermal stability temperature of comparative example 2, comparative example 3 and comparative example 4 are higher than those of example 1, example 2 and example 3 because no benzoic acid is contained in comparative example 2, no potassium permanganate and oxalic acid are added in comparative example 3, and no hydrochloric acid is added in comparative example 4, the product of the invention used as the outer wrapping material of the optical cable needs better flexibility, so a certain amount of plasticizer needs to be added, the invention selects benzoic acid as the plasticizer, the benzoic acid is mixed with C7-C9 alcohol, dioctyl phthalate acts together, the flexibility of the product is increased, and phosphorus trichloride is added, the phosphorus trichloride can be combined with partial benzoic acid to generate benzoyl chloride, the benzoyl chloride is an excellent ultraviolet absorbent, and can enhance the ultraviolet resistance of the product, the stability of the product under strong light is enhanced, excessive potassium permanganate is added to oxidize methyl on a toluene aromatic ring to form carboxyl, potassium benzoate is formed, the potassium benzoate is an antimicrobial agent and can increase the corrosion resistance of the product, and in addition, the rest permanganate is added with oxalic acid to obtain manganese dioxide precipitate, and the manganese dioxide precipitate is filtered and removed. Because benzoic acid can cause consumption in the preparation process, the plasticizing effect is reduced, hydrochloric acid is added and can react with potassium benzoate to obtain benzoic acid for supplement, the toughness of the product is ensured, potassium permanganate and calcium carbonate are combined to generate a phosphate compound which is used in a compounding way with a heat stabilizer, and the heat resistance of the product is improved.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
