Problems solved by technology

The existing calcium-plastic corrugated board is mainly made of high-density polyethylene (HDPE) with filler calcium carbonate and various additives. Due to the development of society, the consumption of chemical raw materials is increasing. The price is increasing year by year. If you continue to use the conventional formula to produce calcium-plastic panels, the cost will become higher and higher. Therefore, it is necessary to adopt a new low-cost calcium-plastic panel production formula to replace the existing technology, which has become an urgent need

preparation example Construction

[0015] (1) Preparation of modified calcium carbonate:

[0016] Ingredients in proportion: heavy calcium carbonate 42%, light calcium carbonate 50%, talcum powder 6%, chlorinated paraffin 2%, put the weighed formula component raw materials into a high-speed mixer, stir at a temperature of 55°C for 15 Minutes, obtain modified calcium carbonate;

[0017] (2) Weigh the materials according to the proportion, knead and stir the weighed raw materials, control the temperature at 95-105°C, and knead in the kneader for 5-8 minutes;

[0018] (3) Mixing and plasticizing: the kneaded mixture enters the internal mixer, at a temperature of 180°-205°C, mechanically pressurizes 35-45Mpa, and plasticizes for 7 minutes;

[0019] (4) Open refining and plasticizing: the mixed material after banbury mixing enters the open mixer, at a temperature of 180°-205°C, mechanically presses 35-45Mpa, and plasticizes for 10 minutes; then enters the rolling and plasticizing process;

Abstract

The invention provides a calcium plastic corrugated board. The calcium plastic corrugated board has a layer structure, consists of a surface calcium plastic paper layer, a core calcium plastic corrugated paper layer and a bottom calcium plastic paper layer, has the total thickness of 3.6 to 4.2mm and the corrugated rib number of 18 to 20 pieces / 100mm, and is prepared from the following raw material components in part by weight: 7 to 8 parts of polyethylene, 20 to 30 parts of modified calcium carbonate, 20 to 25 parts of calcium plastic return material, 0.4 to 0.6 part of stearic acid, 0.01 to 0.03 part of white oil, 0.3 to 0.5 part of titanium dioxide, 0.08 to 0.12 part of ultramarine blue and 0.08 to 0.12 part of whitening agent. A method comprises the following steps of: preparing the modified calcium carbonate, and preparing the calcium plastic board according to the conventional process for producing the calcium plastic corrugated board. The calcium plastic board is low in raw material cost, the process is simple, various performance indexes of a calcium plastic box prepared from the calcium plastic board meet the national standard requirements, and the raw material cost of the calcium plastic box is greatly reduced.

Description

technical field [0001] The invention relates to packaging materials, in particular to a calcium-plastic corrugated board and a production method thereof. Background technique [0002] Compared with paper corrugated board, calcium-plastic corrugated board has the advantages of light weight, firmness, mildew resistance, and good sealing performance. It is used to make packaging boxes and is popularized rapidly. Single-layer calcium-plastic corrugated board is made of surface calcium-plastic paper, core layer of calcium-plastic corrugated board, and bottom layer of calcium-plastic paper. It is a common material for packaging boxes. Its thickness is ≥ 4mm and the number of corrugated ribs is 13 / 100mm. The existing calcium-plastic corrugated board is mainly made of high-density polyethylene (HDPE) with filler calcium carbonate and various additives. Due to the development of society, the consumption of chemical raw materials is increasing. The price is increasing year by year. I...
