Problems solved by technology

At present, when processing and preparing luminous PE resin, the luminous powder is generally mixed directly with the PE resin used and then blow molded or injection molded. The mass fraction of luminous powder in the obtained product is 5%-15%, but there are PE luminous masterbatches on the market Problems such as uneven dispersion of luminous powder, low content of luminous powder, black color of masterbatch, low luminous brightness, short luminous time, and reduced mechanical properties of molded parts after adding this kind of masterbatch

preparation example Construction

[0047] The preparation of the graft polymer is a routine experiment for those skilled in the art, and will not be described in detail in the present invention.

[0048] Further, the above-mentioned dispersant is a hyperbranched polymer. For example, at least one of C100, C181, HyPerC10, HyPerC20, HyPerC30 and HyPerC40 produced by Guangdong Fujiang Chemical Reagent Co., Ltd. can be used. The use of the above-mentioned dispersant can further promote the uniform mixing of the luminous powder and the PE resin, prevent the aggregation of the luminous powder, and reduce the aging of the PE resin, thereby ensuring the luminous effect of the long-lasting PE masterbatch.

[0049] Further, the heat stabilizer is a stearic acid compound, preferably a stearate, more preferably zinc stearate or calcium stearate, the use of the above heat stabilizer can further reduce the aging of the PE resin during the preparation process, ensuring Long afterglow PE masterbatch has bright luminous color,...

Embodiment 1

[0064] This embodiment provides a long afterglow PE masterbatch, the composition of raw materials is as follows, 68.5g of PE-MAH (maleic anhydride modified polyethylene, grafting rate of 0.5%), 0.5g of C100 dispersant, 1g of Zinc Stearate, 30g of BL-2A Luminous Powder.

[0065] This embodiment also provides a preparation method of long afterglow PE masterbatch:

[0066] Add each component to the mixer and mix for 3 minutes in a mixer with a rotation speed of 100r / min. After mixing evenly, add it to a twin-screw extruder with a rotation speed of 200r / min, and melt at 140°C After blending and extruding, it is granulated, then dried, and packaged to obtain long-lasting PE masterbatch.

Embodiment 2

[0068] This embodiment provides a long afterglow PE masterbatch, the composition of raw materials is as follows, 64gPE-MAH (grafting rate 0.5%), 1gC181 hyperdispersant, 5g calcium stearate, 30g of GL-8C luminous powder.

[0069] This embodiment also provides a preparation method of long afterglow PE masterbatch:

[0070] Add each component to the mixer and mix for 10 minutes in a mixer with a rotation speed of 200r / min. After mixing evenly, add it to a twin-screw extruder with a rotation speed of 500r / min and melt it at a temperature of 150°C. After blending and extruding, it is granulated, then dried, and packaged to obtain long-lasting PE masterbatch.

Abstract

The invention relates to the technical field of composite materials and in particular to a long-afterglow PE (polyethylene) master batch and a preparation method thereof, a PE plastic part and a preparation method thereof. The long-afterglow PE (polyethylene) master batch comprises the following raw materials in parts by weight: 28-68.5 parts of a PE resin, 0.3-1 part of a dispersant, 0.5-5 partsof a thermal stabilizer and 30-70 parts of luminous powder, and the luminous powder and the PE resin in the long-afterglow PE master batch are in bonding. The content of the luminous powder in the long-afterglow PE master batch is up to 30-70%, the luminous powder is uniformly dispersed, and the long-afterglow PE master batch is bright in color, long in light emission time and high in brightness.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a long afterglow PE masterbatch, a preparation method thereof, a PE plastic part and a preparation method thereof. Background technique [0002] Glow in the dark powder is aluminate activated by a variety of rare earth ions, which can continue to glow in the dark for a long time after being irradiated by light and heated. Polyethylene (PE for short) is a kind of thermoplastic PE resin obtained by polymerization of ethylene. Good resistance to most acid and alkali corrosion, insoluble in common solvents at room temperature, low water absorption, excellent electrical insulation. The luminous material made by adding luminous powder to PE resin plastic can be widely used in toys, decoration, clothing, outdoor signs and other fields. At present, when processing and preparing luminous PE resin, the luminous powder is generally mixed directly with the PE resin used and the...
