Embodiment Construction

[0011] Concrete technical scheme of the present invention is:

[0012] (1) Biodegradable tableware: its raw material formula includes 100 parts of biodegradable masterbatch, 0-100 parts of polyolefin resin, 0-100 parts of plastic filling masterbatch, 0-12 parts of color masterbatch, and 0 parts of lubricating and dispersing agent ~3 parts, 0~2 parts of degradation aid, 0~10 parts of hygroscopic agent.

[0013] (2) Preparation method of biodegradable tableware:

[0014] 1. Casting blister molding method is also called one-step method: pour the material into the casting blister molding equipment, heat and extrude the diaphragm, and introduce it into the blister mold when it is still in a molten state, and immediately suck and cool it. Forming, and then punching, sorting, inspection, disinfection, packaging and other processes to become products.

[0015] 2. The sheet suction (punching) plastic method is also called the two-step method, that is, the material is firstly heated a...

Abstract

A biodegradable dining set is prepared from biodegradable starch-base mother material, polyolefin resin, plastic filler, pigment, lubricating disperser, degradating aid, and moisture absorbent through proportionally mixing, heating, extruding to become sheet, moulding, and cooling.

Description

Technical field: [0001] The invention relates to a biodegradable tableware and a preparation method thereof. Background technique: [0002] Existing plastic fast food utensils are widely used in the field of food packaging with its advantages of acid resistance, alkali resistance, corrosion resistance, and lightness, low price, attractive appearance, and easy manufacture. However, most of the plastic tableware is made of polymer polyolefin resin, and these materials are difficult to degrade for one or two hundred years, causing serious pollution to the human environment. For a long time, plastics discarded along the railway Fast food boxes have formed the famous "white pollution". Invention content: [0003] The invention solves the problem that the existing plastic fast food tableware is difficult to degrade, and provides a biodegradable tableware that can be swallowed by microorganisms and has a fast degradation speed. [0004] Another object of the present invention i...
