一次性玉米澱粉餐具的成型很（hěn）簡單

A starch foaming disposable tableware is prepared by mixing 86-93 parts by weight of modified corn starch, 0.8-1.2 parts by weight of mold release agent zinc stearate, 0.2-0.4 parts by weight of accelerator potassium sorbate, 1.5-2 parts by weight of thickener sodium polyacrylate, 45-53 parts by weight of stabilizer and several parts by weight of water, and then hot pressing;

穩定劑，是將（jiāng）木漿纖維和改性穀殼（ké）按1∶1.5～2的重（chóng）量比混和製得。

The stabilizer is prepared by mixing wood pulp fiber and modified rice husk in the weight ratio of 1 ∶ 1.5-2.

優選地，它是由89重（chóng）量份的改性玉米澱粉1重（chóng）量份的脫（tuō）模劑硬脂酸鋅、0.3重量份的促進劑山梨酸鉀（jiǎ）、1.8重（chóng）量份的（de）增稠劑聚丙烯酸鈉、50重量份的穩（wěn）定劑、若幹重量份的水（shuǐ）混合攪（jiǎo）拌得到混合（hé）料後，經熱壓成型得（dé）到。

Preferably, it is prepared by mixing 89 parts of modified corn starch, 1 part of mold release agent zinc stearate, 0.3 part of accelerator potassium sorbate, 1.8 part of thickener sodium polyacrylate, 50 parts of stabilizer and a number of parts of water to obtain the mixture, and then hot pressing.

進一步，所述的改（gǎi）性玉米澱粉，是將玉米澱粉、茶多（duō）酚和水按1∶0.22～0.28∶1.5～1.8的質量比混合後（hòu），在35KHz下超（chāo）聲處理35～40min，抽濾，將濾液濃縮濾液體積的1/2，得改性液備用，將濾渣烘幹含水量為6～7％，粉（fěn）碎即得改性玉米澱粉，其中，水溫為30℃。

Furthermore, the modified corn starch is prepared by mixing corn starch, tea polyphenols and water in the mass ratio of 1:0.22-0.28:1.5-1.8, ultrasonic treatment at 35kHz for 35-40min, pumping and filtering, concentrating the filtrate to 1 / 2 of the filtrate volume to obtain the modified solution for standby, drying the filter residue until the water content is 6-7%, crushing to obtain the modified corn starch, in which the water temperature is 30 ℃.

進一步，所述（shù）的穩定劑，是先將穀殼粉碎過80～100目篩（shāi）後，再放入改性液中，水浴（yù）加熱30℃，熬製成含（hán）水量在45～50％的浸膏，在加入（rù）木漿纖維，拌勻即可（kě）。

Furthermore, the stabilizer is to crush the rice husk through 80-100 mesh sieve, then put it into the modified liquid, heat it in water bath to 30 ℃, boil it into an extract with 45-50% water content, and then add wood pulp fiber and mix well.

進一步，其製備方法是將改性玉米澱粉、硬脂酸鋅、山梨酸鉀、聚丙烯酸鈉、穩定劑按比例混合，加水調（diào）製（zhì）成含水（shuǐ）量（liàng）為9～13％的膏狀固（gù）體，按需求放入模具（jù）當中，熱壓成（chéng）型即（jí）可。

Furthermore, the preparation method is to mix the modified corn starch, zinc stearate, potassium sorbate, sodium polyacrylate and stabilizer in proportion, add water to prepare a paste solid with a water content of 9-13%, put it into a mold according to the demand, and then hot press it.

進一步，所述的熱壓成（chéng）型，溫（wēn）度為120～150℃，壓力為0.15～0.2MPa。

Furthermore, the temperature of the hot pressing molding is 120-150 ℃, and the pressure is 0.15-0.2mpa.

綜上所述，本發明的（de）有（yǒu）益效果在於：本發明澱粉含量高，極大地降低（dī）生（shēng）產成本，以玉米澱粉（fěn）為主要原料，利用茶多酚對其進行改性，並輔以多種功能助劑製得發泡餐盒，該發泡餐具受（shòu）熱後不會（huì）產生任何有毒成分，並在（zài）自然條件下可轉化成易被降解的物質，環保，可有效保護環境；

To sum up, the beneficial effects of the invention are as follows: the starch content of the invention is high, the production cost is greatly reduced, the corn starch is used as the main raw material, the tea polyphenols are used to modify it, and a variety of functional additives are supplemented to prepare the foaming lunch box, the foaming tableware will not produce any toxic components after being heated, and can be converted into easily degradable substances under natural conditions, which is safe and environmentally friendly It can effectively protect the environment;

和木漿纖（xiān）維的韌性，有效的支撐餐具（jù）的塑形性，采用茶（chá）多酚對玉米澱粉進行（háng）改性，利用茶（chá）多酚的（de）強烈的抗氧化性，使得製（zhì）備的餐具具有更長久的保質期（qī），將穀殼浸泡於剩餘的改性液中，一是有效回收茶多酚和澱粉溶液，二是利（lì）用茶多酚具有的和抗輻射作用，有效地阻止放射性物質，使得製備的餐具更加衛生。

Tea polyphenols were used to modify corn starch, and the strong antioxidation of tea polyphenols made the tableware have a longer shelf life. Soaking rice husk in the remaining modified solution, one is to effectively recover tea polyphenols and starch solution, the other is to use the detoxification and anti radiation effect of tea polyphenols, which has a great value It can effectively prevent radioactive substances and make the prepared tableware more safe and hygienic.

山梨酸鉀，有效（xiào）地抑製（zhì）黴菌，酵母菌和好氧性細（xì）菌的活性，還能防止肉毒杆菌、葡萄球菌、沙門氏菌等（děng）有害（hài）微生物的生長和繁殖（zhí），其抑止（zhǐ）發（fā）育的作用（yòng）比（bǐ）作用更強，使得本發明長期存放不產生（shēng）黴變。

Potassium sorbate can effectively inhibit the activities of molds, yeasts and aerobic bacteria, and can also prevent the growth and reproduction of harmful microorganisms such as botulinum, Staphylococcus, Salmonella, etc., and its growth inhibition effect is stronger than bactericidal effect, so that the invention does not produce mildew after long-term storage.
