Embodiment 1

[0020] Preparation of masterbatch.

[0021] Put 51 parts of corn starch proportioned according to the requirements into the high-mixing pot for pre-mixing and dehumidification. When the temperature in the pot reaches the set temperature of 120°C, start stirring at a low speed and stir at 600 rpm for 20 minutes to detect the water content of the material. The rate is below 2%.

[0022] Add 8 parts of maleic anhydride E, 1 part of lubricant, 0.05 part of coupling agent, and 0.005 part of stabilizer into the above-mentioned cornstarch with qualified water content, carry out high-speed thermal mixing, start high-speed stirring, and stir at 1600 rpm for 10 minutes, Make the material in the pot fully dissolve into uniform white granules.

[0023] Put the above mixed white granular material into the cold mixing pot and stir to cool at low speed. After cooling to the set temperature, add 1 part of plasticizer, and cold mix for 5 minutes at low speed.

[0024] The above-mentioned coo...

Embodiment 2

[0030] Preparation of masterbatch.

[0031] Put 60 parts of corn starch according to the required ratio into the high-mixing pot for pre-mixing and dehumidification. When the temperature in the pot reaches the set temperature of 120°C, start stirring at a low speed and stir at 650 rpm for 18 minutes to detect the water content of the material. The rate is below 2%.

[0032] Add 10 parts of maleic anhydride E, 1 part of lubricant, 0.07 part of coupling agent, and 0.008 part of stabilizer to the above-mentioned cornstarch with qualified water content, carry out high-speed thermal mixing, start high-speed stirring, and stir at 1600 rpm for 10 minutes, Make the material in the pot fully dissolve into uniform white granules.

[0033] Put the above mixed white granular material into the cold mixing pot and stir to cool at low speed. After cooling to the set temperature, add 1 part of plasticizer, and cold mix for 5 minutes at low speed.

Abstract

Disposable environment-friendly tableware and a manufacturing process thereof belong to the technical field of tableware manufacture. The disposable tableware product produced by a traditional manufacturing process by adopting a master method has the defects of high brittleness, low starch content and high evaporated residual slag content. The manufacturing process disclosed by the invention comprises three steps, namely master preparation, film preparation by extrusion and plastics sucking moulding. The manufacturing process is characterized in that during master preparation, maleic anhydride E resin, starch and a lubricating agent are fused and mixed to from granular materials; the materials are directly input into an extrusion granulator for extruding to form a strip shape; strip materials enter a dicing cutter for dicing; breaking work procedures are reduced, the process flow is shortened and the addition amount of the starch is promoted; in the second step, assistants such as master, polypropylene and TMC-300 nucleating agent are sequentially added into a high mixer; the mixer is input into an extruder for stretching and extruding; and the extruded component is subjected to three-roll crushing, cooling and setting by using circulating water to form a film. Due to the addition of the TMC-300 nucleating agent as the assistant, the physical and mechanical performances of the product are improved and the thermal deformation temperature, strong modulus and the impact resistant strength of the product are improved.

Description

technical field [0001] The invention belongs to the technical field of tableware manufacturing, in particular to a disposable environment-friendly tableware and a manufacturing process thereof. Background technique [0002] Since the early 1990s, a composite material of corn starch and thermoplastics has appeared as a material for the production of disposable tableware. It has attracted much attention in the business community because of its good environmental friendliness, especially around 2000. Corn starch The production of disposable tableware from / PP composite materials has become the focus of new product investment and development in various places. The production process mainly adopts the masterbatch method. The main process flow is: first mix starch, additives and polyethylene into a mixed material, cool After crushing, it is melt-extruded to prepare a masterbatch, and then the masterbatch is mixed with polypropylene raw materials and extruded into a film, and then ...
