Embodiment 1

[0050] The ratio of the above preferred composition of the present invention forms a translucent resin composition with a fragrant smell, including:

[0051] After heating a part of diisononyl phthalate to 120°C~160°C (this temperature range is the temperature for melting styrene-ethylene-butylene-styrene copolymer), the styrene-ethylene- Add butylene-styrene copolymer and stir to melt. Because the overall temperature of styrene-ethylene-butylene-styrene copolymer will be greatly reduced after adding diisononyl phthalate (endothermic reaction), it is necessary to continue heating during the stirring and dissolving process, and maintain the temperature at 100 ° C ~ 160 ° C ℃. After the styrene-ethylene-butylene-styrene copolymer is completely melted, do not heat again, then add the remaining diisononyl phthalate and stir evenly, then add polyvinyl chloride, stearic acid and essential oil to mix Together and stir well. A translucent resin composition with an aromatic smell wa...

Embodiment 2

[0053] Through the following steps, the plastic product with aromatic smell of the present invention can be obtained:

[0054] Send the uniformly stirred resin composition into the barrel of the screw extruder, the temperature of the barrel of the extruder is 110°C-120°C, and the heating time is about 3 minutes. After the semi-finished product is extruded by the extruder, wait for After it is cooled, it is pulverized with a pulverizer.

[0055] Then proceed to the following steps a) or b)

[0056] a) Feed the crushed resin composition in step 2 into the barrel of another screw extruder, and set the temperature of the barrel of the extruder to between 110°C and 120°C, and the heating time is about 3 minutes, After the finished product is extruded by the extruder, it is immediately cooled in a water bath (the lower the water temperature, the better, the temperature of the water bath usually used is about 12°C) to accelerate the solidification of the finished product and reduce ...

Abstract

The present invention relates to translucent aromatic resin composition and its plastic products, and is especially one kind of translucent aromatic resin composition with high molecular ductibility, high absorption on essential oil and high cohesive force. The translucent aromatic resin composition consists of PVC powder 20-50 wt%, diisononyl benzene dicarbonate 20-35 wt%, stearic acid 0.1-0.5 wt%, styrene-ethylene-butene-styrene copolymer 1-6 wt%, and essential oil 20-38 wt%. The products of the translucent aromatic resin composition have compact structure, lasting fragrance, and high marketability.

Description

technical field [0001] The invention relates to a fragrance-releasing resin composition, in particular to a translucent resin composition with fragrance that can be used for direct injection or extrusion molding of articles and its aromatic plastic product. Background technique [0002] The long-lasting deodorant composition of Taiwan Patent Announcement No. 425426 is formed by mixing polyvinyl chloride powder, calcium carbonate, diisononyl phthalate, stearic acid and essential oils, and its design focuses on: 1) Add the most essence in the smallest volume to achieve the convenience of use (small size); 2) Strong and long-lasting effect (the purpose of adding the most essence); 3) Different production methods (injection, compression) can be used Out) allows manufacturers to carry out a variety of different shape designs. After the verification of the market, there are already many products using this patented product (such as photo 1). [0003] Although this patent already...
