Embodiment 1
[0045]Example 1: The biodegradable starch packaging material is composed of the following raw materials: 70% starch, 4% viscose staple fiber, 8% pulp board, and 18% additives. Mix the raw materials in the above ratio, add water, the ratio of water to raw materials is 52:48, stir evenly, put it into a storage tank for standby. The material in the storage tank is injected into the heated mold with an injection gun, and it is made by foam molding. The additives include 70% of asbestos powder, 20% of glycerin and 10% of liquid paraffin.
Embodiment 2
[0046] Example 2: The biodegradable starch packaging material is composed of the following raw materials: 80% starch, 3% viscose staple fiber, 6% pulp board, and 11% additives. Mix the raw materials in the above ratio, add water, the ratio of water to raw materials is 52:48, stir evenly, put it into a storage tank for standby. The material in the storage tank is injected into the heated mold with an injection gun, and it is made by foam molding. The additives include 70% of asbestos powder, 20% of glycerin and 10% of liquid paraffin.
Embodiment 3
[0047] Example 3: The biodegradable starch packaging material is composed of the following raw materials: 76% starch, 3.4% viscose staple fiber, 7.2% pulp board, and 13.4% additive. Mix the raw materials in the above ratio, add water, the ratio of water to raw materials is 52:48, stir evenly, put it into a storage tank for standby. The material in the storage tank is injected into the heated mold with an injection gun, and it is made by foam molding. The additives include 70% of asbestos powder, 20% of glycerin and 10% of liquid paraffin.
[0048] The manufacturing equipment for implementing biodegradable starch packaging materials and products according to the present invention includes a storage tank 1, a metering pump 3, an injection molding gun 4, a special injection molding machine (mainly composed of a frame 5.1, a horizontal hydraulic press 5.9, a pneumatic reversing feeder) material valve 2 and hydraulic, pneumatic and electrical control systems).
