Abstract

The invention discloses a fall resistant and antibacterial PP plastic meal box and a preparation method thereof. The meal box comprises the following raw materials, by weight: 100 parts of PP resin, 50-100 parts of bagasse, 5-10 parts of chitosan, 5-15 parts of shell powder, 10-20 parts of nanometer calcium carbonate, 3-6 parts of a sepiolite fiber, 1-2 parts of phytic acid, 1-3 parts of a modifier, 0.5-2 parts of a coupling agent, 1-2 parts of a plasticizer, 0.5-1.5 parts of an antioxidant, 0.5-2 parts of a composite antibacterial agent, 1-3 parts of cocoamidopropyl betaine, and 3-5 parts ofcarboxymethyl cellulose. The modifier consists of octa(aminophenyl)silsesquioxane and polyethylene glycol stearate in a ratio of 1:1-3. The preparation method adopts the unique raw material formula and coordination effect of the components, the compatibility is good, and the prepared PP plastic meal box has the advantages of high strength, strong impact resistance, fall resistance, wear resistance, weather resistance, high temperature resistance, aging resistance, deformation resistance, good stability, good antibacterial effect and the like, is good in processing performance, simple in process and low in cost, and has good market prospects.

Description

technical field [0001] The invention belongs to the technical field of plastic products, and in particular relates to a drop-resistant and antibacterial PP plastic lunch box and a preparation method thereof. Background technique [0002] PP, also known as polypropylene, is a semi-crystalline material that is harder and has a higher melting point than polyethylene (PE) plastic. PP resins have excellent moisture absorption resistance, acid and alkali corrosion resistance, and solubility resistance. Because PP plastic has the advantages of light weight, no rust, good insulation, etc., it is widely used in chemical industry, building materials, home appliances, automobiles, lunch boxes and other fields. [0003] Today's lunch boxes made of PP plastics have the characteristics of light weight, bright and calm surface, good chemical resistance, excellent chemical stability, electrical insulation, and non-toxicity. They also have low impact strength and tensile strength, and insuf...
