Description
Technical field
The invention belongs to disposable tableware field, more particularly to a kind of degradable disponsable tableware and preparation method thereof.
Background technology
The disposable tableware demand in China is huge, is mostly plastic products or paper products.The plastics system of industrialized production
Product are largely difficult to degrade, and Heavy environmental pollution is also resulted in while fossil energy is consumed；Paper products can bring forest again
The problems such as felling, film difficult degradation, water resource waste, and cost is higher.
At present, the degradable dinner set in China is mainly prepared by raw material of starch, and environment protecting tableware is prepared using stalk
Have the advantages that utilization ratio is high, easily reclaim.A kind of table ware made of stalk disclosed in Chinese Patent Application No. 98124818.7, by straw
Stalk, urea-formaldehyde moulding powder, filler or calcium stearate (or flour) are prepared by stirring, mixing, extrusion forming, and the tableware is in light weight, anti-
Pressure, processing technology is simple, but causes toughness insufficient because lacking adhesive, frangible；Chinese Patent Application No. 99115359.6 is public
Opened a kind of method that degradable dinner set is produced using plant haulm and fruit shell as raw material, the tableware be first by plant haulm and
Adhesive is added after the processing of fruit shell and is mixed, adds plaster mold drying after forming, then be made through surface coating drying, finished product
Degradation property it is good, it is nontoxic, but the forming method of raw material determines that product strength is bad, and processing technology is complicated；In
State's number of patent application 01127386.0 discloses a kind of once-used degradeable tableware and its manufacture method, tableware by degradable major ingredient,
Refined after adhesive, filler mashing mixing through vacuum pugmill, normal temperature shaped by fluid pressure, drying and processing, surface spraying interleaving agent
Be made, tableware rigidity is high and can be adjusted by matching adjustment, and degradation property and toughness are preferable, but its using corn flour and
Bletilla striata powder makees adhesive, and toughness of products is bad after drying, and the interleaving agent such as water-based polyurethane used in product has poison gas before curing
Body discharges；Chinese Patent Application No. 01108832.X discloses one kind and eaten by easily degradable disposable made of primary raw material of starch
Tool, the 70%-90% of tableware is starch, then is aided with a small amount of stalk fibre, vegetable oil and additive, through once hot-forming, into
The coating of surface waterproofing glue is carried out after type, the tableware mainly turns into starch, and therefore degradation property is good, and cost is low, nontoxic, tasteless, but
Itself primary disadvantage is that solidification after starch present fragility cause product tensile strength poor, it is broken.
