Problems solved by technology

[0003] The use of low-density polyethylene to manufacture plastic hoses for cosmetic packaging bottles facilitates the processing and molding of plastic hoses. However, when the use temperature of cosmetic packaging bottles is low, the cosmetic packaging bottles made of low-density polyethylene have poor flexibility. , it is more laborious to squeeze the cosmetics out of the bottle

Embodiment 1~7

[0038] As shown in Table 1, the main difference of Examples 1-7 is that the proportioning of raw materials is different.

Embodiment 1

[0040] A plastic hose for a cosmetic bottle is molded by the following steps:

[0041] (1) Place 40kg of polyethylene in a dryer and dry it for 2 hours at a temperature of 75°C;

[0042] (2) Stirring: 40kg of dried polyethylene, 20kg of ethylene octene copolymer, 20kg of polydimethylsiloxane PEG-8 polyacrylate, 2.5kg of dioctyl phthalate, and 2.5 kg of nano calcium carbonate kg, hydroquinone 1.5kg, dioctadecyl thiodipropionate 1.5kg are stirred by a mixer to obtain mixed raw materials;

[0043] (3) Extrusion: Send the mixed raw materials into the extruder, the melting temperature in the extruder is 125°C, and the molten resin in the extruder is collected into the die head to obtain the tube blank;

[0044] (4) Shaping: first cool the tube blank to get the tube body; then add 25kg of PE 8008, 8kg of PE 2045 and 5kg of PE218 into the head injection machine to inject the head of the tube body; The body is sealed to obtain a plastic hose for cosmetic bottles.

Embodiment 8~10

[0048] The difference between Examples 8-10 and Example 6 is that the proportioning of the plasticizer is different.

Abstract

The invention relates to the technical field of cosmetic packaging, and particularly discloses a pipe blank of a plastic hose for a cosmetic bottle, a preparation method and the plastic hose. The pipe blank comprises the following components in parts by weight: 40-60 parts of polyethylene, 20-40 parts of an ethylene-octene copolymer, 20-40 parts of polydimethylsiloxane PEG-8 polyacrylate, 5-10 parts of a plasticizer and 3-5 parts of an antioxidant, and by adding the ethylene-octene copolymer and polydimethylsiloxane PEG-8 polyacrylate, the flexibility of the plastic hose is improved. The preparation method of the pipe blank of the plastic hose for the cosmetic bottle comprises the following steps: (1) drying materials; (2) stirring; and (3) extrusion molding. The plastic hose for the cosmetic bottle comprises an injection head and the pipe blank, the injection head comprises, by weight, 20-30 parts of PE 8008, 5-15 parts of PE 2045 and 1-10 parts of PE 218, and a hose body is prepared by cooling the pipe blank; and the injection head is prepared from the PE 8008, the PE 2045 and the PE 218, so that the flexibility of the prepared plastic hose is further improved.

Description

technical field [0001] The application relates to the technical field of cosmetic packaging, more specifically, it relates to a tube blank of a plastic hose for a cosmetic bottle, a preparation method and the plastic hose. Background technique [0002] At present, cosmetic packaging usually adopts polyethylene, polypropylene, polyethylene terephthalate and polyvinyl chloride materials. When cosmetic packaging bottles need soft materials, polyethylene is often used. According to different molecular chain structures, polyethylene can be divided into high-density polyethylene, low-density polyethylene and linear low-density polyethylene, with low-density polyethylene being the most common. [0003] The use of low-density polyethylene to manufacture plastic hoses for cosmetic packaging bottles facilitates the processing and molding of plastic hoses. However, when the use temperature of cosmetic packaging bottles is low, the cosmetic packaging bottles made of low-density polyethy...
