Embodiment 1

[0035] Example 1 Manufacture of single-layer stone paper micro-honeycomb paperboard (refer to image 3 )

[0036] a. Raw material granulation process Single-layer micro-stone paper honeycomb paperboard uses 75 parts of natural inorganic mineral powder (mainly composed of calcium carbonate, including calcium sulfate, barium sulfate, mica powder, zinc oxide, dolomite powder, talcum powder, silicon dioxide, etc.) as the main raw material , with 20 parts of HDPE (high density polyethylene), 2.3 parts of modifiers (including 0.8 parts of aluminate, 1 part of JL-G modifier, 0.5 parts of stearic acid), 2.1 parts of processing aids (including 0.6 1 part of polyvinyl ester CH-4, 1.5 parts of solid paraffin 56#), 2 parts of functional additives (calcium carbonate modified whitening agent). First, the main raw material, natural inorganic mineral powder, is mixed and dried; then the dried inorganic materials and modifiers are added to the mixing / modification equipment and mixed to ...

Embodiment 2

[0041] Example 2 Manufacture of double-layer stone paper honeycomb paperboard (reference Figure 4 )

[0042] a. Raw material granulation processDouble-layer stone paper honeycomb paperboard uses 75 parts of natural inorganic mineral powder (mainly composed of calcium carbonate, including calcium sulfate, barium sulfate, mica powder, zinc oxide, dolomite powder, talcum powder, silicon dioxide, etc.) as the main raw material. With 20 parts of HDPE, 2.3 parts of modifiers (including 0.8 parts of aluminate, 1 part of JL-G modifier, 0.5 parts of stearic acid), 2.1 parts of processing aids (including 0.6 parts of polyvinyl ester CH-4 , 1.5 parts of solid paraffin wax 56#), 2 parts of functional additives (calcium carbonate modified whitening agent). Then activate the modified inorganic materials and functional additives 、 The processing aid and HDPE are added to the mixing equipment and mixed evenly, put into the granulation equipment 1, and banburyed in the granulation equip...

Abstract

The invention discloses a stonepaper honeycomb cardboard comprising a honeycomb paper element and two pieces of surface papers, wherein the two pieces of surface papers are compounded on an upper surface and a lower surface of the honeycomb paper element, and the paper core and the surface papers are made of stonepaper. The invention also discloses a manufacturing method of the stonepaper honeycomb cardboard. The manufacturing method comprises the following step of carrying out palletizing, extruding-molding, hot-smelting compounding on the stonepaper as a raw material to form the stonepaper honeycomb cardboard. The stonepaper honeycomb cardboard disclosed by the invention has the structural advantages of a traditional fiber-paper honeycomb cardboard and also integrates excellent performances of the stonepaper; the manufactured stonepaper honeycomb cardboard has the advantages of high physical strength, good oil resistance, good corrosion resistance, excellent dampproof and waterproofperformances, excellent printing performance after surface treatment, simple production process and low cost; the production process is anhydrous and environment-friendly without pollution; the stonepaper honeycomb cardboard has the certain degradability under natural environment and is a novel green environment-friendly packaging material.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and relates to a stone paper honeycomb paperboard and a manufacturing method thereof. Background technique [0002] At present, the traditional fiber paper honeycomb paperboard circulating in the market has been used as packaging material in China for many years. It is mainly composed of two-layer paper, honeycomb core layer and sandwich paper (single-layer honeycomb paperboard without sandwich paper). [0003] Due to the water absorption of the fiber paper itself, the moisture-proof and waterproof performance of the fiber paper honeycomb paperboard is very poor. In addition, the traditional fiber paper honeycomb paperboard is relatively thick, high rigidity, not easy to bend, and difficult to post-processing. It is generally used as trays and cushioning pads, but it is rarely used in boxes. The surface of traditional fiber paper honeycomb paperboard is generally rough, and its flatn...
