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(wěn)定劑，是將木漿纖維和改性谷殼按1∶1.5～2的重量比混和制得。

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

優(yōu)選地，它是由89重量份的改性玉米淀粉1重量份的脫模劑硬脂酸鋅、0.3重量份的促進(jìn)劑山梨酸鉀、1.8重量份的增稠劑聚丙烯酸鈉、50重量份的穩(wěn)定劑、若干重量份的水混合攪拌得到混合料后，經(jīng)熱壓成型得到。

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(jìn)一步，所述的改性玉米淀粉，是將玉米淀粉、茶多酚和水按1∶0.22～0.28∶1.5～1.8的質(zhì)量比混合后，在35KHz下超聲處理35～40min，抽濾，將濾液濃縮濾液體積的1/2，得改性液備用，將濾渣烘干含水量為6～7％，粉碎即得改性玉米淀粉，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(jìn)一步，所述的穩(wěn)定劑，是先將谷殼粉碎過80～100目篩后，再放入改性液中，水浴加熱30℃，熬制成含水量在45～50％的浸膏，在加入木漿纖維，拌勻即可。

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(jìn)一步，其制備方法是將改性玉米淀粉、硬脂酸鋅、山梨酸鉀、聚丙烯酸鈉、穩(wěn)定劑按比例混合，加水調(diào)制成含水量為9～13％的膏狀固體，按需求放入模具當(dāng)中，熱壓成型即可。

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(jìn)一步，所述的熱壓成型，溫度為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(fā)明的有益效果在于：本發(fā)明淀粉含量高，極大地降低生產(chǎn)成本，以玉米淀粉為主要原料，利用茶多酚對其進(jìn)行改性，并輔以多種功能助劑制得發(fā)泡餐盒，該發(fā)泡餐具受熱后不會產(chǎn)生任何有毒成分，并在自然條件下可轉(zhuǎn)化成易被降解的物質(zhì)，環(huán)保，可有效保護(hù)環(huán)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;

和木漿纖維的韌性，有效的支撐餐具的塑形性，采用茶多酚對玉米淀粉進(jìn)行改性，利用茶多酚的強(qiáng)烈的抗氧化性，使得制備的餐具具有更長久的保質(zhì)期，將谷殼浸泡于剩余的改性液中，一是有效回收茶多酚和淀粉溶液，二是利用茶多酚具有的和抗輻射作用，有效地阻止放射性物質(zhì)，使得制備的餐具更加衛(wèi)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，有效地抑制霉菌，酵母菌和好氧性細(xì)菌的活性，還能防止肉毒桿菌、葡萄球菌、沙門氏菌等有害微生物的生長和繁殖，其抑止發(fā)育的作用比作用更強(qiáng)，使得本發(fā)明長期存放不產(chǎn)生霉變。

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.
