Description
Technical field
The present invention relates to plastic manufacturing technology fields, and in particular to a kind of fast degradation environmentally-friendly plastic.
Background technology
Plastics are a kind of synthetic materials, are one of the main materials that modern people use, with the development of the times at me
Plastic industry of the state as one of light industry pillar industry, in recent years growth rate be always held at 10% or more, keeping
While very fast development speed, economic benefit also has new raising.The above enterprise's output value total value of plastic article industry scale is light
Third is occupied in 19 main industries of work, realizes sales ratio of industrial enterprises 97.8%, is higher than light industry average level.It is set from synthesis
From the point of view of fat, plastics machinery and plastic products production, the powerful growth momentum of China Plastics Industry is all shown.
Nowadays plastic material has become essential material in daily life, and number of applications and range are also all with day
Increase, but plastic material product live and offer convenience for us while, also results in the great burden of environment, traditional plastics are not
It is degradable, a large amount of noxious materials are will produce after burning, so the research direction of plastic material is mostly Degradable environment protection direction now,
Now also there are many degradable plastic products on the market, but this plastics have degradation time length mostly, incomplete etc. ask of degrading
Topic, Ren Ranhui cause great burden and pollution to environment, so being badly in need of a kind of plastics of the quick and complete degradation of energy now.
Invention content
In view of the shortcomings of the prior art, the present invention provides a kind of fast degradation environmentally-friendly plastic, the degradation speed of plastics is accelerated,
Keep plastic degradation complete simultaneously, has many advantages, such as environmentally friendly, pollution-free.
In order to achieve the above object, technical scheme of the present invention is achieved by the following technical programs：

Preferably, a kind of fast degradation environmentally-friendly plastic, is made of the raw material of following parts by weight：70 parts of polyvinyl resin, phenol
18 parts of urea formaldehyde, 35 parts of soybean starch, 12 parts of epoxy resin, 4 parts of polyvinyl alcohol, 8 parts of cellulose, 3 parts of diaryl iodonium salt, oxygen
Change 2.1 parts of zinc, 3 parts of cosolvent, 4 parts of plasticiser.
Wherein, the soybean starch first passes through the epoxy-modified processing of dimethyl siloxane before use；The cosolvent is
1: 1 mixture of sodium salicylate and acetamide；The plasticiser is di-n-octyl phthalate.
The present invention provides a kind of fast degradation environmentally-friendly plastic, and advantage is compared with prior art：
(1) diaryl iodonium salt is added in plastics of the present invention, zinc oxide is photosensitizer, while starch and epoxy resin is added,
Make plastics of the present invention that there is light, the dual degradability of biology, after the starch of plastics is biodegradable, plastic raw materials high polymer parent
Become loose, increases surface area, while daylight, heat, oxygen etc. cause photosensitizer, lead to high polymer chain rupture, molecular weight and molecular weight so that drop
Speed is solved to accelerate.
(2) soybean starch used in plastics of the present invention first passes through the epoxy-modified processing of dimethyl siloxane before use,
In decomposable process more fully completely, no plastic components remain plastics made of so that.
(3) present invention selects sodium salicylate in raw material selection and 1: 1 mixture of acetamide is cosolvent, phthalic acid
Di-n-octyl is plasticiser, and ingredient is environment friendly and pollution-free, reduces the harmful substance that plastics generate in decomposable process.
