GRANULAR STABILIZER PRODUCT

Full Description BACKGROUND The present invention relates to a granular stabilizer ws product and further specifies; Relates to a granular stabilizer product which tends to avoid any hydrolysis even after prolonged storage; Thus, a stable function of inhibiting thermal degradation and oxidation degradation can be achieved when the granular stabilizer product is added to an organic material; It is considered excellent in terms of applicability. Organic materials Jie thermoplastic resins and Jie thermosetting resins Ag polyolefin polyester are associated with degradation of the physical property of the resist; Colds flowability; coloring; deterioration of the physical property of the surface; and 0 similar organic matter arising from the phenomena of Jie severing of molecules and entanglement between molecules caused by the effects of heat; oxygen; and the like during its production and processing and in addition to that; use it; Its value as a commodity may be greatly diminished. oof is known as JE phenol-based oxidation inhibitor “phosphorus-based oxidation inhibitor” or similar that is added to organic matter 5 to solve problems Jie thermal degradation and oxidative degradation 1. The patented oxidation degradation f oxidation inhibitor acts as a stabilizer for organic matter and achieves the effect of inhibiting any thermal degradation and any oxidative degradation during production; processing; and in addition to So; use organic matter.

Patent Document 1: Open Patent Publication SLL No. 273494-10. GENERAL DESCRIPTION OF THE INVENTION Problems solved by the invention when 530) a phosphorus—based oxidation inhibitor is prolonged; however, a hydrolysis reaction occurs. When an oxidation inhibitor is added

SE in which the hydrolysis reaction to organic matter takes place; Processing stability becomes non-inhibited and organic matter of consistent quality cannot be obtained. When an inhibitor of phosphorus-dependent oxidation is added to the organic matter; A bridging phenomenon may occur, which makes it difficult to uniformly add the oxidation inhibitor to the organic matter, and the function of suppressing thermal degradation 0 and oxidation degradation may be disrupted. The purpose of the present invention is to provide a granular stabilizer product which tends to avoid any hydrolysis of it even after it has been stored for a period of time; which achieves a stable inhibition function for any thermal degradation and any oxidative degradation when the granular stabilizer product is added to the organic matter; It is considered excellent by Cun 5 1 Problem Solving Means to solve previous problems; The inventors actively studied the particle stabilizer products in detail and completed the present invention. The present invention has the following preferred applications.

The evaluation methods are as follows. Its results are shown in Table 1. Evaluation of hydrolysis resistance Each of the stabilizers is stored in a constant Hla pH and hygroscopic bath at Hla 2° 50 and Hla 5 680 RH for 4 weeks and then its acid value is calculated according to JIS 1992 0070 Titration method using phenolphthalein color change. Lower acid value means greater hydrolysis resistance. The result is shown in Table 1. Evaluation of the downstream property of GAS each of the A through L stabilizers in a constant temperature and wet bath at 0 50 C and 9680 RH for 4 weeks and then 100 g of It is fixed in a mouth with a stopcock having an opening of 100 mm and an outer bottom diameter of 25 mm. The time period is measured from

The time from which the stopcock is removed to the time the entire retainer falls out. A shorter downward period of time means a greater downflow characteristic. The result of this is shown in Table 1. Table 1:

— 9 3 — ee *: The stabilizer does not fall down due to the bridge phenomenon. Industrial Applicability The granular stabilizer product of the present invention tends to avoid any hydrolysis even after long-term storage; with a tendency to avoid any bridge phenomenon that occurs to him; It may be added uniformly to organic matter. A granular stabilizer product that can therefore be available can achieve a stable function of inhibiting any thermal degradation and any oxidative degradation when the granular stabilizer product is added to an organic matter; It is considered excellent in terms of applicability.
