[0050] Among them, the rotating speed of the high-speed mixer is 150~180rpm, first stir at a low speed to make the four kinds of raw materials mix evenly.

[0051] S200, adding 0.5-3 parts by weight of epoxidized soybean oil or DOP, and stirring for 3-5 minutes.

[0052] Continue to keep the speed of the high-speed mixer at 150~180rpm, and add epoxy soybean oil or DOP to disperse the materials.

[0053] S300, adding 0.05-0.5 parts by weight of an antioxidant, stirring for 5-10 minutes to obtain self-made ZH04A.

[0054] Wherein, the antioxidant is 1010 antioxidant. Adjust the speed of the high-speed mixer to 450~500rpm, add 1010 antioxidant, st...

Embodiment 1

[0074] A method for preparing a packaging box, comprising the following steps:

[0075] 1. Preparation of self-made ZH04A

[0076] The ACR of 3 parts by weight, the calcium-zinc stabilizer of 3 parts by weight, the polyethylene wax of 0.8 parts by weight, and the stearic acid of 0.8 parts by weight are placed in a high-speed mixer, and stirred at a speed of 150 rpm for 5 min;

[0077] Add the epoxidized soybean oil of 0.8 weight part, stir 3min;

[0078] After adjusting the speed of the high-speed mixer to 450rpm, add 0.05 parts by weight of 1010 antioxidant, and stir for 5 minutes to obtain self-made ZH04A.

[0079] 2. Mixing

[0080] The bamboo powder of 45 parts by weight, the calcium carbonate of 5 parts by weight are placed in the high mixer, after stirring at a low speed of 450rpm for 5min, the rotating speed of the high mixer is adjusted to 1500rpm until the temperature of the high mixer rises to 70°C;

[0081] After adjusting the speed of the high mixer to 450rpm, a...

Embodiment 2

[0092] A method for preparing a packaging box, comprising the following steps:

[0093] 1. Preparation of self-made ZH04A

[0094] The ACR of 5 parts by weight, the calcium-zinc stabilizer of 5 parts by weight, the polyethylene wax of 1 part by weight, the stearic acid of 1 part by weight are placed in a high-speed mixer, and stirred at a rotating speed of 180rpm for 5min;

[0095] Add the epoxidized soybean oil of 1 weight part, stir 3min;

[0096] After adjusting the speed of the high-speed mixer to 450rpm, add 0.08 parts by weight of 1010 antioxidant, and stir for 5 minutes to obtain self-made ZH04A.

[0097] 2. Mixing

[0098] The bamboo powder of 50 parts by weight, the calcium carbonate of 15 parts by weight are placed in the high mixer, after stirring at a low speed of 450rpm for 5min, the rotating speed of the high mixer is adjusted to 1500rpm until the temperature of the high mixer rises to 70°C;

[0099] After adjusting the speed of the high mixer to 450rpm, add 1...

Abstract

The invention provides a wood-plastic composite material for a packaging box and a packaging box preparation method. The wood-plastic composite material is prepared from, by weight, 100-110 parts of PVC (polyvinyl chloride) resin, 30-60 parts of biomass fibers, 10-50 parts of calcium powder, 3-8 parts of self-made ZH04A, 0.1-1 part of a color toner and 0.5-5 parts of a defoaming agent. The self-made ZH04A is prepared from, by weight, 2-8 parts of ACR, 2-8 parts of a calcium-zinc stabilizer, 0.05-0.5 part of an antioxidant, 0.5-3 parts of epoxidized soybean oil or DOP (dioctyl phthalate), 0.5-3 parts of polyethylene wax and 0.5-3 parts of stearic acid. The wood-plastic composite material for the packaging box has advantages that due to combination of the various raw materials, the biomass fibers can be dispersed completely to be well distributed along with other chemical agents, and the wood-plastic composite material crusts the surface of a packaging box product obtained by injection molding to realize uniform appearance glossiness and mild handfeeling of the packaging box.

Description

technical field [0001] The invention relates to the field of packaging boxes, in particular to a wood-plastic composite material for packaging boxes and a preparation method for the packaging box. Background technique [0002] The modern packaging industry is still dominated by paper packaging, wood product packaging, and plastic packaging. However, with the country's restrictions on wood and the rising price of high-grade wood, it is imminent to find an alternative material; and the environmental problems of plastic products are getting worse. The promulgation of the national plastic restriction order has a more obvious impact on plastic packaging boxes; therefore, the application of wood-plastic composite materials to the packaging industry is an opportunity of an era. [0003] Packaging box is a product that has high requirements on appearance and feel. The application of wood-plastic composite material injection molding to the packaging industry is still a new field. It...
