Abstract

The invention discloses a composite packaging material and a preparation method thereof. The packaging material is prepared from a carrier material, adhesive resin and organic silicone resin; the carrier material is dipping brown paper, and the amount of the brown paper is 75-125g / m<2>; the adhesive resin is melamine formaldehyde resin or melamine urea formaldehyde resin suitable for dipping, and the solid content of the resin is 45-70%; and the organic silicone resin is prepared from 3-15 parts by weight of methyltrichlorosilane, 5-13 parts by weight of diphenyl dichlorosilane, 8-16 parts by weight of dimethyldiethoxylsilane and 2-9 parts by weight of silicon carbide. The packaging material prepared in the invention has the advantages of very good heat and weather resistance, easy decomposition, and no pollution to environment.

Description

technical field [0001] The invention relates to the field of packaging materials and production methods thereof, in particular to a composite packaging material and a preparation method thereof. Background technique [0002] The main function of the packaging material is to protect the product so that it reaches the consumer intact. Once this function of packaging is fulfilled, it is thrown away, or even littered around. Regardless of the method used, the used packaging must always be disposed of. If the packaging materials are decomposed easily and can be easily restored to the natural environment, then the pollution problems of land and sea can be solved. But this is not the case. Even vegetable plants, if there are no conditions suitable for bacterial growth, will not decompose after being buried in the ground for ten years, let alone packaging materials. [0003] Decomposition of packaging material occurs only when exposed to a medium that causes it to decompose. It ...
