傳統(tǒng)的一次性發(fā)泡餐具，主要指發(fā)泡聚苯乙烯餐具，由于迎合了當(dāng)代人追求生活快捷、方便、衛(wèi)生的要求，加上成本低廉，一經(jīng)問(wèn)世，便在范圍內(nèi)迅速得到應(yīng)用和推廣，但是由于聚苯乙烯的難降解，對(duì)環(huán)境造成極大的污染，隨著經(jīng)濟(jì)的高速發(fā)展和對(duì)環(huán)境保護(hù)意識(shí)的增強(qiáng)，原來(lái)受歡迎的、快速便捷的、不可降解一次性發(fā)泡聚苯乙烯餐具，被有關(guān)部門(mén)列為限期淘汰產(chǎn)品，鑒于此，如何制造一種既對(duì)生態(tài)環(huán)境沒(méi)有污染危害、對(duì)人、成本低廉、又能充分降解、使用性能好等綜合優(yōu)勢(shì)的塑料餐具替代產(chǎn)品，

The traditional disposable foam tableware, mainly refers to the expanded polystyrene tableware, because it caters to the contemporary people's pursuit of fast, convenient and sanitary requirements, coupled with low cost, once it came out, it has been rapidly applied and promoted all over the world. However, due to the difficult degradation of polystyrene, it causes great pollution to the environment. With the rapid development of economy and environmental protection With the enhancement of awareness, the once popular, fast, convenient and non degradable disposable expanded polystyrene tableware has been listed as a product to be eliminated within a time limit by the relevant departments of the state. In view of this, how to make a plastic tableware substitute with comprehensive advantages such as no pollution to the ecological environment, no toxicity to people, low cost, full degradation and good performance,

一種淀粉發(fā)泡的一次性餐具，它是由86～93重量份的改性玉米淀粉、0.8～1.2重量份的脫模劑硬脂酸鋅、0.2～0.4重量份的促進(jìn)劑山梨酸鉀、1.5～2重量份的增稠劑聚丙烯酸鈉、45～53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；

The utility model relates to a disposable tableware with starch foaming, which is prepared by mixing 86-93 weight parts of modified corn starch, 0.8-1.2 weight parts of mold release agent zinc stearate, 0.2-0.4 weight parts of accelerator potassium sorbate, 1.5-2 weight parts of thickener sodium polyacrylate, 45-53 weight parts of stabilizer, and some weight parts of water to obtain the mixture, which is hot pressed;

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 made of 89 parts by weight of modified corn starch, 1 part by weight of zinc stearate, 0.3 parts by weight of accelerator potassium sorbate, 1.8 parts by weight of thickener sodium polyacrylate, 50 parts by weight of stabilizer and some parts of water, which are mixed and stirred to obtain the mixture, and then hot pressed.

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, suction filtration, concentration of the filtrate to 1 / 2 of the volume of the filtrate to prepare the modified solution for use, drying the filter residue to the water content of 6-7%, crushing to obtain the modified corn starch, wherein the water temperature is 30 ℃.

進(jìn)一步，所述的穩(wěn)定劑，是先將谷殼粉碎過(guò)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 chaff through 80-100 mesh sieve, then put it into the modified liquid, heat it to 30 ℃ in a water bath, boil the extract with water content of 45-50%, 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。

Further, the preparation method is to mix the modified corn starch, zinc stearate, potassium sorbate, sodium polyacrylate and stabilizer in proportion, add water to prepare paste solid with water content of 9-13%, put it into the 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 hot pressing molding temperature is 120-150 ℃, and the pressure is 0.15-0.2mpa
