Problems solved by technology

[0002] At present, a large number of convenient tableware made of foamed plastics are still being used in the market. The disposable convenient tableware made of foamed plastics pollutes the environment after use. , however, it has been banned repeatedly due to the low price, and the subsequent substitute products such as paper convenience tableware, straw products, etc. have high prices
The Chinese patent (patent number: ) discloses a method of utilizing cornstarch material to manufacture fully degradable packaging products. Although the method solves the degradation problem of the material, there are still some problems to be solved in production due to the complicated process, such as, After the raw material is expanded, it has good plasticity and toughness at high temperature, and can be processed to change its shape at this time. After cooling, it no longer has plasticity and toughness, and can no longer change its shape. In the above-mentioned patent, it is used after cooling. The method of steam humidification, puffed corn is very easy to absorb water, after absorbing water, it spreads soft, and then pressed into shape. The foamy sponge function of the expanded material

Embodiment 1

[0018] A method for producing disposable convenience tableware with puffed corn:

[0019] (1) select corn with lower price in the grain as raw material, process it into 3-5mm corn dregs after screening, and the water content is 13%-17%;

[0020] (2) expand the corn dregs with an extruder;

[0021] (3) A cutter and a flattening shaft roller are installed at the outlet of the Penghua machine, and the materials are cut and flattened in a hot state;

[0022] (4) When the temperature of the material is 150-180 ° C, the above-mentioned sheet-shaped puffed material is pressed and formed with a wheel-type convex-concave molding machine, and the thickness is 4-5 mm;

[0023] (5) After the product is pressed and formed, when the temperature drops to 50-60°C, the inner and outer surfaces are sprayed with a waterproof adhesive layer; when the product temperature is 50-60°C, it contains 17%-20% of moisture; it still has a certain degree of toughness;

[0024] (6) Natural cooling, inspect...

Embodiment 2

[0026] A method for producing disposable convenience tableware with puffed corn:

[0027] (1) select corn with lower price in the grain as raw material, process it into 3-5mm corn dregs after screening, and the water content is 13%-17%;

[0028] (2) expand the corn dregs with an extruder;

[0029] (3) A cutter and a flattening shaft roller are installed at the outlet of the Penghua machine, and the materials are cut and flattened in a hot state;

[0030] (4) When the temperature of the material is 150-180 ° C, the above-mentioned sheet-shaped puffed material is pressed and formed with a wheel-type convex-concave molding machine, and the thickness is 4-5 mm;

[0031] While the sheet-shaped puffed material is pressed and formed by a wheel-type convex-concave molding machine, the degradable plastic film is directly pressed on the surface of the inner and outer layers by using the puffed material at a high temperature of 150-180 ° C. Spikes, used to pierce the plastic film, rele...
