Problems solved by technology

However, with these known methods, none of the above-mentioned problems can be sufficiently improved.
[0004] It is considered that the thermal oxidation stability or color phase stability of the polyolefin resin composition containing the inorganic filler is lowered because the thermal oxidation stabilizer added to prevent thermal oxidation aging is inert by the inorganic filler, or Incapable of fully exerting its effect due to being broken down

Embodiment 1

[0037] (1) Make the main rubber

[0038]9 kg of monopolypropylene powder manufactured by Sumitomo Chemical Co., Ltd. with a melting flow rate of 15 g / 10 minutes, 400 g of ethylene dioctadecamide (trade name: Amowax EBS) manufactured by Laioh Acso Co., Ltd., and synthetic water manufactured by Kyowa Chemical Industry Co., Ltd. 100 g of talc (trade name: DHT-4A), 200 g of Iroganokus 1010 (manufactured by Chiba Supesharitoi Kumikalzu Co., Ltd.) as a phenolic antioxidant, and 300 g of Irogahosu 168 (manufactured by Chiba Supesharitoi Kumikalzu Co., Ltd.) as a phosphate-based antioxidant were added together. To a rotary mixer and mix for 30 minutes. Then, using Toshiba Machinery Co., Ltd.'s twin-screw extruder TEM35B (rotating 2 strips in the same direction), melt extrusion was carried out under the conditions of extrusion temperature 200°C, screw rotation number 300rpm, and extrusion rate 20kg / hour. The mixture is pressed and granulated by means of multiple sets of cutters to obt...

Embodiment 2

[0045] Except when making the mixture containing inorganic filling in (2) of embodiment 1, change the single polypropylene powder into 6kg, talc 4kg, coordinate antioxidant Irogahonkus1010, 0.2 parts by weight and in the mixture of the two Except for 4 parts by weight of the main compound made in item (1) of example 1, the same method as item (2) of embodiment 1 was used to make a mixture. In addition, this mixture was repeatedly extruded by the same method as in (3) of Example 1, and the melt flow rate, GO life at 150°C (primary product), coloring, and odor were similarly evaluated for these extruded products. The results are shown in Table 1.

Embodiment 3

[0047] A mixture of 8 kg of single polypropylene powder with a melting flow rate of 15 g / 10 minutes manufactured by Sumitomo Chemical Co., Ltd. and 2 kg of talc (trade name: fine white powder 5000s) manufactured by Hayashi Kasei Co., Ltd. as an inorganic filler was added to the mixture of Example 1. 2 parts by weight (200 g) of the main compound prepared in (1), after rotating and mixing for 30 minutes, the same method as in (2) of Example 1 was used to prepare a mixture (called a primary product).

[0048] In addition, this mixture was repeatedly extruded by the same method as in item (3) of Example 1, and for these extruded products, the melt flow rate, GO life at 150°C (only for primary products), coloring, and odor were evaluated in the same manner. . The measurement results are shown in Table 1.

Abstract

The present invention relates to a kind of polyolefine resin composite and mixture, in the polyolefine resin containing inorganic filling agent the hydrotalcite compound, compound represented by general formula R-CO-NH-(CH2)n-HN-CO-R (where R is alkyl or alkenyl of C5-C21, n is 1-6), phenol series antioxidant and phosphate series antioxidant can be added. Said composite and mixture can improve recirculating property of polyolefine resin containing inorganic filling agent, and their thermal oxidation stability, smell and colour phase stability are good.

Description

technical field [0001] The present invention relates to a main compound composition capable of remarkably improving thermo-oxidative stability, odor and hue stability when recycling polyolefin resin containing an inorganic filler, and a mixture capable of improving its recyclability. technical background [0002] In order to improve the mechanical properties of polyolefins such as rigidity, impact resistance, dimensional stability, and heat resistance, a method of compounding inorganic fillers is usually used. However, the addition of an inorganic filler has the disadvantage of remarkably lowering its thermo-oxidative stability, odor, and hue stability compared to a product without the addition of a filler. Especially in recycling use, this tendency is more remarkable through the heating process, and improvement is eagerly desired. [0003] So far, various schemes have been proposed in order to improve thermal oxidation aging or smell, discoloration (for example, JP-A No. 5...
