Silk and glass fiber blended antifungal aviation food bag and preparation method thereof

Abstract

The invention discloses a silk and glass fiber blended antifungal aviation food bag and a preparation method thereof. The aviation food bag is prepared from, by weight, 50-60 parts of glass fiber, 8-15 parts of calcium carbonate, 1-4 parts of nanometer titania, 10-20 parts of benzoin ethyl ether, 7-9 parts of nano-montmorillonite, 1.2-1.4 parts of tetrabutyl titanate, 12-14 parts of ramie sticks, 60-65 parts of silk, 2-3 parts of gelatin, 1-2 parts of magnesium stearate, 13-15 parts of acetyl tributyl citrate, 1-1.5 parts of 2,6-di-tert-butyl-4-methylphenol, 4-6 parts of 3-hydroxybenzoic acid, 1-2 parts of laurinol sulfate and 4-6 parts of plant saponins. The product is produced according to a safe formula and can be used for preparing the aviation food package bag and the like, the product is high in strength, resistant to water and oil and durable in use in the use process, large-scale industrial production is easy, grasping is easy, popularization is convenient, the abandoned product can automatically decompose into carbon dioxide and water under the effect of rich oxygen and microorganisms, and the food bag is ecological and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of plastic films, in particular to a silk-glass fiber blended anti-mold airline food bag and a preparation method thereof. Background technique [0002] In recent years, due to the increasingly serious "white pollution" caused by waste plastics that are difficult to degrade, it has attracted widespread attention from all over the world. Countries around the world have successively issued relevant laws and regulations restricting or prohibiting the use of non-degradable plastic packaging. On the other hand, because petroleum, the raw material for making traditional plastics, is a non-renewable resource, it will be exhausted with the massive use of human beings. Therefore, it is imminent to develop environmentally friendly plastics that use renewable resources as raw materials and are degradable. [0003] The use of biodegradable silk materials to prepare degradable packaging films has become a research hotspo...

Problems solved by technology

However, while silk improves the degradability of plastics, on the one hand, it will cause a decrease in its physical and mechanical properties, making it difficult to process. On the other hand, it is too hydrophilic and has poor compatibility with most general-purpose resins. Poor, resulting in a significant decline in the mechanical properties of the film, poor water resistance, thus hindering the wide application of silk plastics in the process of industrialization

Glass fiber is a kind of high molecular polymer with a wide range of uses. Its properties are between plastics and rubber. It contains a large number of polar hydroxyl groups. Flexibility, smoothness, oil resistance, solvent resistance, protective colloid, gas barrier and water resistance after special treatment, and also has certain biodegradability, 6 under the condition of bacteria in wet environment It can be completely decomposed into water and carbon dioxide within a month. It is a completely biodegradable material, but the degradation process has high requirements on the degradation environment, so the degradation rate is still relatively slow.
