Problems solved by technology

However, these studies are mainly focused on the establishment of physical performance analysis models of traditional corrugated cardboard and the improvement of its manufacturing process to improve its performance.
There is no method that can essentially overcome the above-mentioned defects of traditional corrugated cardboard, so the application of corrugated cardboard in the packaging industry has been greatly limited

Embodiment 1

[0037] Embodiment 1: the manufacture of U-shaped stone paper composite corrugated cardboard

[0038] 1. Stone paper raw material granulation U-shaped stone paper composite corrugated cardboard with 75 parts of natural inorganic mineral powder (mainly composed of calcium carbonate, also includes calcium sulfate, barium sulfate, mica powder, zinc oxide, dolomite powder, talcum powder, Silicon oxide, 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 Parts of processing aids (including 0.6 parts of polyvinyl ester CH-4, 1.5 parts of paraffin wax 56#), 2 parts of functional aids (calcium carbonate modified whitening agent). In this stage, the raw material of stone paper corrugated board is manufactured into pellets. First, 75 parts of natural inorganic mineral powder (including calcium carbonate, calcium sulfate, barium sulfate, ...

[0042] Example 2: Manufacture of UV type stone paper composite corrugated board

[0043] The manufacture of UV-type stone-paper composite corrugated board is basically the same as that of the U-shaped stone-paper composite corrugated board in Example 1 above. The differences can be explained in two parts: raw materials and manufacturing process.

[0044] In terms of raw materials, UV-type stone paper composite corrugated cardboard uses 80 parts of natural inorganic mineral powder (the main component is calcium carbonate, and also includes 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 polyethylene Ester CH-4, 1.5 parts of solid paraffin wax 58#) and 2.1 parts of functional additives (1.5 parts of titani...

Abstract

The invention discloses a stone paper corrugated board. The surface paper and the core paper of the stone paper corrugated board are made of stone paper with high calcium carbonate content; and the stone surface paper and the stone core paper are totally combined into a corrugated integrated structure. The invention also discloses a manufacturing method of the stone paper corrugated board. The manufacturing method comprises the following steps of: extruding and pelleting the stone paper raw material, rolling an extruded flow to manufacture a stone paper corrugated core, and performing hot-melting composite molding on the stone paper corrugated core and the stone surface paper at high temperature instant. The advantage of the stone paper can be developed fully; and as the stone paper has certain plasticity, in the produced stone paper corrugated board, a bonding agent is not needed, and the produced stone paper corrugated board has high physical performance, is dampproof, waterproof and corrosion resistant, and is a novel environment-friendly packaging material.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and relates to a stone paper corrugated cardboard and a manufacturing method thereof. Background technique [0002] Paper and cardboard play a leading role in packaging materials, accounting for more than 40% of all packaging materials, and even reached 50%. As an important part of paper packaging materials, corrugated cardboard has already been widely used. [0003] Traditional corrugated cardboard is a multi-layer bonded body, which consists of at least one layer of corrugated core paper and two layers of paper. Its corrugated corrugations are like connected arched doors, arranged in a row with each other, supporting each other, forming a triangular structure, which has good mechanical strength, can withstand certain pressure from the plane, and is full of elasticity and cushioning effect. Good; it can be made into liners or containers of various shapes and sizes according to need...
