Technical Field

The present invention relates to a nucleating agent, a synthetic resin composition containing the same, and a molded article thereof, and more particularly, to a novel nucleating agent capable of imparting excellent transparency to a synthetic resin, a synthetic resin composition containing the same, and a molded article thereof.

Background

Synthetic resins, particularly polyolefin resins, have excellent molding processability, heat resistance, mechanical properties, low specific gravity, and the like, and are widely used for films, sheets, and various molded articles (structural members and the like). However, although the polyolefin-based resin itself generally has excellent physical properties, the polyolefin-based resin may not exhibit the inherent excellent performance of the resin depending on a certain application, and thus the application thereof is sometimes limited.

This disadvantage is caused by the crystallinity of the polyolefin resin. Various nucleating agents are widely used to improve the crystallinity of polyolefin resins and to improve the transparency of the resins.

Examples of the nucleating agent include carboxylic acid metal salts such as sodium benzoate, 4-tert-butyl aluminum benzoate, sodium adipate, and disodium bicyclo [2.2.1] heptane-2, 3-dicarboxylate; phosphate metal salts such as sodium bis (4-t-butylphenyl) phosphate, sodium 2,2 '-methylenebis (4, 6-di-t-butylphenyl) phosphate and lithium 2, 2' -methylenebis (4, 6-di-t-butylphenyl) phosphate; and polyol derivatives such as diphenylmethylenesorbitol, bis (methylbenzylidene) sorbitol and bis (dimethylbenzylidene) sorbitol.

Further, patent document 1 proposes a triamide compound as a nucleating agent for reducing fogging of a polymer. Further, patent document 2 proposes a triaryloxytriazine compound as a stabilizer for improving the thermal stability of halogen-containing resins such as vinyl chloride resins. Further, patent document 3 proposes a triaryloxytriazine compound as a flowability improver for synthetic resins.

[ Synthesis of Compound represented by the general formula (1) ]

Synthesis of nucleating agent (Compound No.5)

A solution was prepared by dissolving 4.8g of sodium hydroxide and 11.29g of phenol in 300mL of water. In a separate flask, 11.1g of cyanuric chloride was dissolved in 300mL of acetone and cooled to 5 ℃ with an ice bath. The prepared phenol solution was slowly dropped over 30 minutes in such a manner that the temperature in the system was kept at 10 ℃ or lower, and after the dropping, the mixture was stirred at room temperature for 1 hour. Thereafter, 300mL of water was added to the reaction solution, and the precipitate was filtered, washed with distilled water, and dried under reduced pressure to obtain a white solid.

Thereafter, in another flask, 2.06g of 4-hydroxybenzamide and 1.59g of sodium carbonate were dissolved in a mixed solvent of distilled water 60 mL/acetone 90mL, and 4.49g of the above white solid was added thereto, followed by stirring at room temperature for 3 hours. Thereafter, 120mL of water was added and the resulting precipitate was filtered, washed with distilled water and dried, whereby about 5g of Compound No.5 was obtained as a white solid.

According to the same procedure, compounds Nos. 1 to 4,6 to 11, 30 to 35, and 49 to 59 described in tables 1 to 8 were synthesized.

The pellets thus obtained were dried at 80 ℃ for 4 hours, and then evaluated as follows. As the nucleating agent, only one which was pulverized in a mortar and passed through a 300 μm sieve before mixing was used.

Pellets were produced and evaluated in the same manner as in example 1, except that 0.05 part by mass of the calcium stearate (lubricant) was not added in example 3, and pellets were produced and evaluated in the same manner as in example 2, except that 0.05 part by mass of the calcium stearate (lubricant) was not added in example 4.

Comparative examples 3 and 4 were evaluated in the same manner as in example 1, except that the following comparative compounds-1 and-2 were used as nucleating agents.

[ method of measuring crystallization temperature ]

Each pellet was heated at a rate of 50 ℃/min to 230 ℃ by a differential scanning calorimeter (diamond; Perkin Elmer Co., Ltd.), and was cooled at a rate of-10 ℃/min to 50 ℃ after being held for 10 minutes, and the peak top of the heat generation peak occurring during the cooling was defined as the crystallization temperature in the spectrum thus obtained. The results are also shown in tables 1 to 8 below.

[ transparency evaluation (Haze value) ]

Injection molding was carried out by an injection molding machine (EC 100-2A; manufactured by Toshiba machine Co., Ltd.) under the following conditions: each pellet was charged into a mold at an injection temperature of 200 ℃ and an injection pressure of 40 to 60MPa for 40 seconds, cooled in the mold at 40 ℃ for 20 seconds, and then the sheet was taken out of the mold, thereby obtaining a sheet having a square shape with a 60mm square on one side and a thickness of 1 mm. The obtained sheet was left standing for 1 week in a thermostatic bath having an in-bath temperature of 23 ℃ immediately after injection molding, and the Haze value of the test piece was determined by Haze Guard 2 (manufactured by Toyo Seiki Seisaku-Sho Ltd.). The lower the value, the better the transparency of the test piece. The results are also shown in tables 1 to 8 below.

The obtained bending test piece was left standing in a thermostatic bath at a bath temperature of 23 ℃ for 1 week immediately after injection molding, and the flexural modulus (MPa) was determined by a bending tester (manufactured by Shimadzu corporation; AG-IS). The results are also shown in tables 1 to 8 below.

[ deflection temperature under load (HDT) ]

Injection molding was carried out by an injection molding machine (EC 100-2A; manufactured by Toshiba machine Co., Ltd.) under the following conditions: each pellet was charged into a mold at an injection temperature of 200 ℃ and an injection pressure of 40 to 60MPa for 40 seconds, cooled in the mold at 40 ℃ for 20 seconds, and taken out of the mold to prepare an HDT test piece having a length of 80mm, a width of 10mm, and a thickness of 4 mm. The HDT test piece thus obtained was left standing in a thermostatic bath at a bath temperature of 23 ℃ for 1 week immediately after injection molding, and then measured by the Flat-Wise method using an automatic HDT testing apparatus (manufactured by Toyo Seiki Seisaku-Sho Ltd.). The test was carried out under conditions of a temperature rise rate of 120 ℃/h and a bending stress of 1.8MPa, and a temperature at which the variation of the test piece due to the load became 0.34mm was defined as a deflection temperature under load (HDT).
