Problems solved by technology

Existing seals are generally made of traditional plastic and color masterbatch, which will leave a little plastic smell, especially for the application of luxury jewelry, the residual smell of plastic base material will give users a bad experience
In addition, in some specific use environments, such as at night or in a dark environment, general seals cannot meet the requirements of quickly finding the location of the plastic seal and the blocked item.

preparation example Construction

[0027] The preparation method of described plastic masterbatch is as follows:

[0028] 1) Add polypropylene copolymer, ethylene-octene copolymer, polyethylene, and zinc stearate into a high-speed mixing pot according to the formula, stir and mix evenly to obtain a mixed material;

[0029] 2) Put the mixed material into a twin-screw extruder, the material stays in the screw for 50 seconds to 100 seconds, melts and extrudes from the twin-screw extruder, cools, dries, and pelletizes to obtain the described Plastic masterbatch.

[0030] In some preferred embodiments, the marine essence includes 1-100 parts of fragrance base, 10-80 parts of solvent, 1-10 parts of surfactant, and 5-50 parts of carrier in parts by weight of raw materials of the marine essence.

[0031] In some preferred embodiments, the fragrance base includes 10-40 parts of citral, 10-40 parts of ambrox, 5-10 parts of ethyl acetate, and 1-30 parts of ethyl ester, 5-15 parts of ethyl valerate, 0.1-10 parts of thymo...

Embodiment 1

[0046] Embodiment 1 provides a light-scented plastic seal. The raw materials for its preparation include 99.1% of plastic masterbatch, 0.5% of marine essence, 0.1% of toner, and 0.3% of luminescent powder in terms of mass percentage.

[0047] Described plastic masterbatch, according to the raw material weight part that plastic masterbatch forms, preparation raw material comprises 70 parts of copolymerized polypropylene; 12 parts; 1 part zinc stearate.

[0048] The copolymerized polypropylene is a random copolymerized polypropylene with a flexural modulus of 850Mpa and a melt flow rate of 7.5g / 10min, which was purchased from Dongguan Chaowang Plastic Raw Materials Co., Ltd., with a brand name of GM750E.

[0049] The polyethylene is linear low-density polyethylene (purchased from Dongguan Jiajia Plastic Raw Material Co., Ltd., brand LL1002AY) and maleic anhydride grafted linear low-density polyethylene (purchased from Xiamen Keaisi Plastic Technology Co., Ltd., brand It is the ...

Embodiment 2

[0064] Similar to Example 1, a kind of fragrance-type plastic seal and its preparation method are provided, but in the raw materials for preparing the plastic seal, by mass percentage, it includes 98.5% of plastic masterbatch; 0.7% of marine essence; 0.2% of toner %; luminescent powder 0.6%.

Abstract

The invention discloses a faint scent type plastic sealing strip and a preparation method thereof. The faint scent type plastic sealing strip is prepared from, by mass, 98.5%-99.5% of plastic masterbatch; 0.1-1% of marine essence; 0.05%-0.5% of a toner; and 0.1-0.6% of luminescent powder. The prepared plastic sealing strip has excellent mechanical properties and proper locking force, can inhibit peculiar smell of plastic, and has the characteristics of no toxicity, no harm, good stability, strong fragrance durability and pleasant faint scent. Besides, the plastic sealing strip has fluorescenceat night or in a dark environment, so that the plastic sealing strip and the position of a blocked object can be quickly found.

Description

technical field [0001] The invention relates to a high-end plastic seal, in particular to a fragrance-type plastic seal and a preparation method thereof. Background technique [0002] The plastic seal is a kind of accessories made of plastic, which is composed of a plastic mouth and a strip body. The strip body can be bent through the front plastic mouth and form a ring for bundling and packaging; because the serrations on the strip body can be combined with the elastic plastic inside the plastic mouth The buckle is tightly closed, so the plastic seal can play a very firm fixing role, and the plastic seal is required to have a suitable locking force and good toughness and strength. [0003] As a tool for locking anti-counterfeit packaging, it is generally applicable to the fields of logistics and luxury jewelry anti-counterfeiting packaging. Existing seals are generally made of traditional plastic and color masterbatch, which will leave a little plastic smell. Especially fo...
