Degradable flame-retardant packaging material and preparation method thereof

Abstract

The invention is applicable to the field of packaging materials, and particularly relates to a degradable flame-retardant packaging material which comprises the following raw materials in parts by weight: 50-80 parts of a resin composite material; wherein the resin composite material comprises the following components: resin, glass fibers, starch, cellulose and a plasticizer. The method for preparing the resin composite material comprises the following steps of: adding the resin, the starch, the cellulose and the plasticizer, uniformly stirring the mixture, adding the glass fibers, and vibrating the mixture while stirring; the material further includes: 15-20 parts of a dispersant, 25-30 parts of a flame retardant, and 70-100 parts of paper pulp. After the resin composite material and thepaper pulp are combined for use, the paper box packaging material is waterproof on the basis of degradability, and the resin and the glass fibers in the resin composite material act on the paper pulpin a matched manner, so that the paper box packaging material has certain tensile strength even if the paper box packaging material is damaged and water enters the paper pulp.

Description

technical field [0001] The invention is applicable to the field of packaging materials, in particular to a degradable flame-retardant packaging material and a preparation method thereof. Background technique [0002] Carton is a kind of paper packaging. It has three major functions of packaging, namely protection function, use function and promotion function. In addition, it has good processing performance and easy molding, and the molding and filling process is easy to realize mechanization, automation and high speed. It is a kind of "green packaging" that can be recycled and does not pollute the environment, and is currently widely used by countries all over the world. [0003] Carton is a paper packaging container formed by folding and pasting cardboard, and the material is mostly thin cardboard. Due to its limited strength, the volume of the carton is generally not too large, and it is mostly used in the outer packaging of small and medium commodities, such as medicine ...

Problems solved by technology

[0007] However, although discarded cartons can be degraded, their waterproofness and airtightness are not very good, and their strength will become weaker in the later stage of damp, especially for shopping bags. Walking outside on rainy days may easily cause packaging paper bags and cartons to be damaged by moisture, while cause items to drop
