Description
Technical field
The invention belongs to environment-friendly materials technical fields, and in particular to the novel degradable environment-friendly materials of one kind and its preparation side
Method.
Background technique
Since population increases and economic development, excessive exploitation and unreasonable development to resource and the influence money that generates
A series of problems of source quality.Wherein, although one time foam tableware is brought convenience to people's lives, it is but given
Environment causes serious white pollution, and this foaming plastic tableware will can degrade in the soil by decades supreme a century,
Processing of such as being burnt generates pernicious gas again, brings serious damage to the living environment of people.
Plastic tableware applied by present, difficult to degrade, bad mechanical strength cause the waste of raw material, and environment causes white
It is seriously polluted.In the prior art, vegetable fiber environmental protection material product such as food containers, disposable tableware, gift wrap, flower
Basin, life adornment and gift handicraft are usually to mix after being ground processing by plant fiber with adhesive, filler
It is prepared under high-temperature and high-pressure conditions using mold.Wherein, plant fiber is mainly taken from rice husk, straw, wheat straw, corn
The agricultural crop straws such as stalk, Cotton Stalk, sawdust, bamboo scraps or the stalk stem of other plants.Adhesive mainly uses natural plant
Or Lauxite, phenolic resin or the melamine resin of formaldehyde series.However, preparing plant fiber environmental protection by mold
During material product, since the toughness of vegetable fiber environmental protection material is poor, to the preparation of vegetable fiber environmental protection material product
Certain difficulty is brought, while also reducing the yield rate of vegetable fiber environmental protection material product.
For polylactic acid as a kind of artificial synthesized high molecular material from renewable plant resources, possessing can be completely biological
Degradability, good machine-shaping ability and excellent mechanical property, as degradation plastic, be subjected to widely pay close attention to
Pay attention to.But polylactic acid is on the high side, and as a kind of thermoplastic macromolecule material, since it is with relatively high
Glass transition temperature, higher crystallinity and longer crystallization time, brittleness is big under low temperature or room temperature, thermal stability under high temperature
Not strong, that there are heat distortion temperatures is low, is easy hydrolysis, the defects of mechanical strength is insufficient, hot processing window is narrow, it is difficult to directly utilization.
Currently, thering is a large amount of research and patent to carry out open report to polylactic acid high molecular material, but there are still poly-
The defects of lactic acid dosage is big at high cost, heat resistance is poor, recycling is difficult.Such as Chinese invention patent ZL200610010449.1
In disclose a kind of preparation method of fire resistant biodegradable agglomerate reinforced by composite inorganic material, the Biodegradable resin used
Content is larger, by weight percentage up to 30%~60%, leads to higher cost, and more difficult in technique processing, economy effect
Benefit is low.A kind of Starchlike biological degradatable plastic mother and its preparation are disclosed in Chinese invention patent ZL200410061416.0
Method, for tacky resin parts by weight up to 30~300 parts, content is higher, added cost, and uses tacky resin graft reaction
Initiator cumyl peroxide and cumyl hydroperoxide keep MAT'L recycling difficult.Chinese invention patent
A kind of biodegradable polymer is disclosed in ZL03135999.X, using native starch and polylactic acid as raw material, is suitable for agriculture
With plastic foil and packaging material for food, but since the glass transition temperature of most of Biodegradable resin is very low (50~70 DEG C), make
The application field for obtaining manufactured goods is restricted.
