传统的一次性发泡餐具制作的过程

传统的一次性发泡餐具，主要指发泡聚苯乙烯餐具，由于迎合了当代人追求生活快捷、方便、卫生的要求，加上成本低廉，一经问世，便在范围内迅速得到应用和推广，但是由于聚苯乙烯的难降解，对环境造成极大的污染，随着经济的高速发展和对环境保护意识的增强，原来受欢迎的、快速便捷的、不可降解一次性发泡聚苯乙烯餐具，被国家有关部门列为限期淘汰产品，鉴于此，如何制造一种既对生态环境没有污染危害、对人安全无毒、成本低廉、又能充分降解、使用性能好等综合优势的塑料餐具替代产品，

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,

一种淀粉发泡的一次性餐具，它是由86～93重量份的改性玉米淀粉、0.8～1.2重量份的脱模剂硬脂酸锌、0.2～0.4重量份的促进剂山梨酸钾、1.5～2重量份的增稠剂聚丙烯酸钠、45～53重量份的稳定剂、若干重量份的水混合搅拌得到混合料后，经热压成型得到；

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;

稳定剂，是将木浆纤维和改性谷壳按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.

优选地，它是由89重量份的改性玉米淀粉1重量份的脱模剂硬脂酸锌、0.3重量份的促进剂山梨酸钾、1.8重量份的增稠剂聚丙烯酸钠、50重量份的稳定剂、若干重量份的水混合搅拌得到混合料后，经热压成型得到。

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.

进一步，所述的改性玉米淀粉，是将玉米淀粉、茶多酚和水按1∶0.22～0.28∶1.5～1.8的质量比混合后，在35KHz下超声处理35～40min，抽滤，将滤液浓缩至滤液体积的1/2，得改性液备用，将滤渣烘干至含水量为6～7％，粉碎即得改性玉米淀粉，其中，水温为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 ℃.

进一步，所述的稳定剂，是先将谷壳粉碎过80～100目筛后，再放入改性液中，水浴加热至30℃，熬制成含水量在45～50％的浸膏，在加入木浆纤维，拌匀即可。

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.

进一步，其制备方法是将改性玉米淀粉、硬脂酸锌、山梨酸钾、聚丙烯酸钠、稳定剂按比例混合，加水调制成含水量为9～13％的膏状固体，按需求放入模具当中，热压成型即可。

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.

进一步，所述的热压成型，温度为120～150℃，压力为0.15～0.2MPa

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