Plant fiber foam packaging material and manufacturing method thereof

Abstract

The invention relates to a plant fiber foam packaging material and a manufacturing method thereof; the method takes plant fiber, oxidized starch, foaming agent, dispersing agent, filler and water repellent agent as raw materials, the materials are uniformly mixed and injected into a mold, the slurry system foams and expands under the effect of the special foaming agent, the buffer packaging product with natural degradation, low cost and good buffering effect can be obtained through demolding and drying. The invention has simple formula, high foaming multiplying power, and simple forming process and is easy for operation.

Description

technical field [0001] The invention relates to a plant fiber foaming cushioning packaging material, and also relates to a manufacturing method of the plant fiber foaming packaging material. Background technique [0002] With the rapid development of industry, the demand for packaging materials is also increasing, especially packaging materials with cushioning properties. Foam plastics, specifically expanded polystyrene (EPS), have been used for years in the cushioning packaging of appliances, electronics, glassware and more. Foam plastics have the advantages of light weight, easy processing, good protection performance, wide adaptability, low price and high quality, etc., but plastic foam materials have the advantages of large volume, difficulty in recycling, non-natural degradation of waste, high regeneration costs, and pollution caused by incineration. Environmental and other ills have caused serious "white pollution" to the environment; at the same time, in the manufact...

Problems solved by technology

This type of foaming agent either has a high foaming temperature and is not suitable for the foaming process of plant fibers, because plant fibers are easy to embrittle and carbonize at high temperatures, while foaming materials such as ammonium bicarbonate, sodium bicarbonate, and sodium carbonate paper Although the gas generation temperature of the agent is relatively low, the gas generation speed is fast, and it is not suitable for the molding of foam materials.

Most of the previous plant fibers were directly crushed into powder, or cut into sections of a certain length, and some used the core of straw as raw materials, but the plant fiber raw materials obtained by these methods lost the properties of the plant fiber itself, such as fiber The effective binding force and interweaving force between them lack the effective utilization of the plant fiber raw material itself
