Problems solved by technology

However, the fine plant fibers in its main component have poor dispersion during molding, which can easily cause uneven air bubbles and fiber agglomeration, which in turn leads to uneven mechanical properties and unstable physical properties of biomass fiber tableware.
In recent years, there have been some exploratory researches on the application of biodegradable polylactic acid in the field of food packaging. However, there are also reports that the corresponding products have defects such as poor temperature resistance and oil resistance, high brittleness, easy deformation, difficult processing and high cost.

Abstract

The invention provides a preparation method of a water-resistant oil-resistant anti-falling bamboo fiber environment-friendly meal box. The method comprises the following steps of cutting 3-4-year-oldround bamboo into bamboo tube sections, processing the bamboo tube sections into bamboo bundle fibers, processing or carrying out rotary cutting and drying to obtain a micro-thin bamboo veneer, coating an adhesive on the to-be-glued surface of the micro-thin bamboo veneer, aging, and laminating to pave longitudinal and transverse assemblies; and the assembled thin bamboo veneers are placed in a prefabricated mold located on a high-temperature mold pressing station to be subjected to hot press molding and then laminated, and the water-resistant, oil-resistant and anti-falling bamboo fiber environment-friendly meal box is obtained. The bamboo fiber environment-friendly meal box is uniform in mechanical property and stable in physical property, has water resistance, oil resistance and falling resistance, and is environment-friendly and safe.

Description

technical field [0001] The invention belongs to the technical field of bamboo processing, and in particular relates to a preparation method of a water-resistant, oil-resistant, drop-resistant bamboo fiber environmental protection lunch box. Background technique [0002] The demand for disposable plastic lunch boxes in the takeaway catering industry is also increasing, which has brought a great burden to the environment in terms of production, utilization, recycling, and disposal. [0003] In the past ten years, the exploration of alternatives to disposable non-degradable plastic tableware has never stopped. Most of the research on the design and preparation of biomass fiber tableware focuses on the use of plant fiber powder or slurry such as wood, straw, straw, bagasse, ramie, and corn. The main material, other additives are auxiliary materials, mixed according to a certain ratio, and made through a series of processes. However, the fine plant fibers in its main component h...
