Problems solved by technology

[0003] As a special color, army green has specific requirements on hue, brightness and saturation, which makes it difficult to prepare army green
At present, there is no military green product manufactured by rotational molding process in China, and no military green colorant formula of rotational molding product has been publicly published in domestic and foreign publications.

Embodiment Construction

[0010] Accurately measure the resin and pigment according to the following formula.

[0011] Linear Low Density Polyethylene 100 parts

[0012] Chrome oxide green 0.41 parts

[0013] Cadmium yellow 0.33 parts

[0014] Iron oxide red 0.083 parts

[0015] Rutile titanium dioxide 0.17 parts

[0016] Medium pigment carbon black 0.0055 parts

[0017] 0.5 parts of liquid paraffin

[0018] Put the taken materials into a high-speed mixer and mix for 10 minutes. The materials were taken out and put into a twin-screw extrusion granulator for granulation, and the temperature of the extruder was set at 120-160□. The prepared colored particles are put into a plastic granule micropowder mill and ground to about 80 mesh. Then put the powder into the rotary molding mold, set the heating temperature to 300□, heat for 20 minutes, and finally cool and demould to obtain the product. The color of the product is uniform, and the color meets the army green standard.

Abstract

The military green colouring agent is formed from (by weight portion) 35-45 portions of green pigment, 30-40 portions of yelloe pigment, 8-10 portions of red pigment, 15-20 portions of white pigment,0.4-0.6 portions of black pigment and 0.5 portions of colouring agent adhesive. It can be used for colouring rotary moulded plastic products with military green, and the colour of the products coloured with said colouring agent is uniform, and is non-discoloring or non-fading under the outdoor condition fo r a long period of time.

Description

Technical field [0001] The invention discloses an army green colorant, and also discloses the application of the army green colorant in rotationally molded plastic products. Background technique [0002] Rotational molding is a process for forming hollow plastic products. Its outstanding advantages lie in the low investment in equipment and molds, and it is suitable for the production of medium and large plastic products with complex shapes. Compared with other molding processes, the rotational molding process is characterized by high processing temperature and long heating time, which makes the coloring of rotationally molded products more difficult. About 200 kinds of pigments can be used for the coloring of polyethylene injection molding and extrusion molding products, but only about 30 kinds of pigments can be used for coloring of rotational molding products. [0003] As a special color, army green has specific requirements on hue, brightness and saturation, which make...
