After end still can not natural biology degraded, be finally difficult to embody the value of environmental protection.
It is the degradable green environment protecting tableware that raw material is made using husk, because its raw material sources is wide, cost is relatively low, produces
Journey is pollution-free, the advantage such as environmental protection, with real degradation capability, increasingly attracts people's attention.But because husk is particle
Shape and powdered, mould heat pressure shaping rule is more complicated, such as mold design not science, will make interiors of products density and other performance
Skewness, influence product final mass and appearance it is attractive in appearance, even result in product distortion and the defect such as crack.Separately
On the one hand, because the higher process high temperature compacting rear mold of husk composite environmental-friendly material moisture content gets rusty easily, most of common material
Expect that die life is shorter.Also, the continuous expansion and change of the market demand, it is desirable to moulding, outward appearance and the usability of product
It must also can be continually changing.Therefore, this project carries out research and development to the mould of husk environment protecting tableware.
The content of the invention
The present invention is for deficiency of the prior art there is provided a kind of to discard the side that husk manufactures environment-protecting product as base-material
Method, the present invention is using agricultural wastes husk as main base, and with low cost, product is attractive and durable, can be biological after product rejection
Degraded.Solving existing tableware can not degrade mostly, the problem of being polluted the environment after discarding.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：It is a kind of using discarded husk as
The method that base-material manufactures environment-protecting product, includes following steps：Step（A）：In terms of mass parts, by 60 parts to 80 parts husks,
10 parts to 20 portions corn flour, 5 parts to 15 parts macromolecule compound resins and 3 parts to 8 parts methenamines are stirred into compound；Step
Suddenly（B）：By percentage to the quality, 3% ~ 5% zinc stearate auxiliary agent is added in compound；Step（C）：Compound is put into
In baking oven, baking oven is gradually gradually warming up to 120 DEG C from 80 DEG C in 40s to 80s, while being preheated to mould, preheating temperature
Degree is between 40 DEG C to 50 DEG C；Step（D）：Compound is put into mould, then 200T to 300T pressure, 145 DEG C extremely
At least 60s is molded at a temperature of 160 DEG C；Step（E）：Semi-finished product are obtained after compound is hot-forming, then semi-finished product are beaten
Mill；Step（F）：Purified treatment is carried out to semi-finished product after the completion of semi-finished product polishing, by pure water or alcohol to surface of semi-finished
Cleaned；Step（G）：To surface of semi-finished coating protective film after half-finished clean is complete, described protection film base material is saturation
The mixture of polyester resin and flatting silica, the thickness of the diaphragm is at 0.04 millimeter to 0.06 millimeter；Step（H）：Half-and-half into
Product carry out baking dehydration, and the time of baking, the temperature of baking was at 80 DEG C to 110 DEG C at 30 minutes to 80 minutes.
In above-mentioned technical proposal, it is preferred that in step, described husk grain diameter is 10 mesh to 30 mesh.
In above-mentioned technical proposal, it is preferred that in step, described corn flour grain diameter is 1500 mesh to 2000 mesh.
In above-mentioned technical proposal, it is preferred that in step G, described saturated polyester resin is resin acrylic resin, institute
The flatting silica stated includes superfine silicon dioxide and talcum powder.
In above-mentioned technical proposal, it is preferred that in step D, 15s to 30s is maintained after molding temperature reaches at least 145 DEG C
Then it is exhausted, exhaust is stripped after terminating.
In above-mentioned technical proposal, it is preferred that in step D, first quick-make, will be closed at a slow speed again when will close during mold closing
Until closing completely.
In above-mentioned technical proposal, it is preferred that in step, described macromolecule compound resin is modified cyanurotriamide first
Urea formaldehyde.
In above-mentioned technical proposal, it is preferred that described mold cavity bottom centre point is provided with convex platform.
Because husk particle and powder are special, shaping rule is sufficiently complex, by powder irregular stacking randomness and
The uneven influence of frictional force between particle and powder, powder and mold wall in pressing process, the husk fiber of prior art leads to
Chang Wufa curing moldings, or the tableware of the fiber containing husk of shaping are unable to reach food-grade requirement, therefore this project follows husk
The characteristic of grain and rice husk powder, using the thermosetting principle of saturated resin as theoretical foundation, carries out the research and development of thermosetting pressing process.
Agricultural wastes husk it is main by graininess and it is powdered constitute, exist through a large amount of polar functional groups such as base.In paddy
In shell composite environmental-friendly material, hydrophilic husk and the resin of hydrophobic can be poor in the presence of higher interface, and both are difficult to melt on interface
Close, it is therefore necessary to which solving above difficult point could succeed the excellent husk composite environmental-friendly material of processability.It is that this is of the invention in original
Methenamine is added in material, the addition of methenamine auxiliary agent can weaken the polarity of husk, so as to improve husk and resin
