Abstract

The invention relates to a production process of a plastic bowl, and belongs to the technical field of plastic production manufacturing. The plastic bowl is manufactured by taking high-density polypropylene granules as the matrix, and taking the PBAT, corn starch, functional auxiliaries, nano talcum powder and modified materials as the auxiliary material, wherein the polypropylene granules as the matrix are prepared by taking polypropylene, glass fiber, polyformaldehyde, thermoplasticity polyester elastomer, deionized water, isopropanol, antioxidant, plasticizer and methyl vinyl silicone oil as the raw materials; and a manufacturing process of the plastic bowl comprises the following steps: weighing raw materials, drying the raw materials, stirring, freezing, mixing, injection-molding, and after-treating; multiple formulas are added for the plastic bowl so that the plastic bowl is endowed with the characteristics of attractive appearance, high heat distortion temperature, good tenacity, excellent performance at all aspects, and biodegradablity after being used. The plastic bowl disclosed by the invention is scientific and rigorous in formula, and also simple and controllable in the production process procedure; the plastic bowl is low in cost and small in pollution, meets the concept of sustainable development, and is worthy of popularizing.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of plastic production and manufacturing, in particular to a production process of a plastic bowl. [0003] 【Background technique】 [0004] Plastic bowls refer to non-toxic and harmless bowls made of food-grade PP materials, which often appear in the catering industry. Based on their light texture, beautiful appearance, low cost and strong plasticity, they are deeply loved by people. [0005] Not only that, the plastic bowl also has the advantages of saving time and effort in processing, and has the advantages of many shape changes, and has developed rapidly in recent years. However, the plastic bowl products currently on the market still have the following problems: 1. The gloss and transparency of the products are average, resulting in an unsightly appearance; The lifespan is short; three, the garbage after use becomes the source of white pollution; four, its production process is complicated, caus...
