Abstract
The invention discloses a biodegradable plastic. The biodegradable plastic is composed of the following components in parts by weight: 40-60 parts of polyethylene, 40-60 parts of polycaprolactam, 1-3 parts of glycerin monostearate and 0.1-2 parts of mosquito/fly repellent material. A preparation method of the biodegradable plastic comprises the following steps: taking the polyethylene and the glycerin monostearate for melting by heating, stirring evenly, slowly adding the polycaprolactam and then adding the mosquito/fly repellent material after cooling to 50-60 DEG C; then cooling rapidly, thereby obtaining the finished product. The biodegradable plastic obtained by the preparation method adopting the technical scheme is high in degradation speed and advantageous for environmental protection; due to the added additives, the mechanical properties of the biodegradable plastic are improved; due to the adopted mosquito/fly repellent material, the biodegradable plastic is applicable to outdoor and severe dinning environment, and is convenient and comfortable.
Description
Technical field
The present invention relates to a kind of plastic material, particularly a kind of biodegradable plastics.
Background technology
Polyethylene is that ethene carries out the macromolecular organic compound that addition polymerization forms.Polyethylene is the contact food best materials of generally acknowledging in the world.Nontoxic, tasteless, odorless, meet food product pack hygienic standard.Polyethylene film, merrily and lightheartedly transparent, there is protection against the tide, antioxygen, acidproof, alkaline-resisting, resistance to air loss is general, the performances such as heat sealability excellence.Maximum, the most important materials of plastic wrapping printing consumption.Due to the annual a large amount of use of polythene material, can cause the generation containing polyethylene waste material in a large number, it is difficult to degraded, easily causes the pollution of environment.
Summary of the invention
The object of the present invention is to provide a kind of biodegradable plastics.It is fast that these plastics have degradation speed, and hardness and friability are moderate, can produce the effect of mosquito repellent fly.
The technical solution that realizes the object of the invention is:
A kind of biodegradable plastics, meter, comprises composition: 40～60 parts of polyethylene by weight; 40～60 parts of polycaprolactams; 1～3 part of glyceryl monostearate; 0.1～2 part of mosquito repellent fly material.Preparation method is for getting polyethylene, glyceryl monostearate, and heating for dissolving, stirs, and slowly adds polycaprolactam, to be cooledly adds mosquito repellent fly material to 50～60 ℃, cooling rapidly, makes biodegradable plastics.
Wherein each component preferred weight umber is 55 parts of polyethylene, 55 parts of polycaprolactams, 2.5 parts of glyceryl monostearates, 0.5 part of mosquito repellent fly material.Its degradation speed is the fastest, and embrittlement degree and hardness are the most moderate.
Wherein mosquito repellent fly material is the polycaprolactam fiber of absorption plants essential oil.The optional lavandula angustifolia of plants essential oil, lemongrass or cloves.
The present invention compared with prior art, its remarkable advantage: contain polycaprolactam and be suitable for biological degradation, degradation speed is fast, is conducive to environment protection; In formula, add glyceryl monostearate, be difficult for embrittlement, hardness is moderate; Contain mosquito repellent fly material, carry mosquito repellent fly function, be applicable to manufacture disposable plastic tablecloth, for open air or the severe environment of having a dinner of sanitary condition.
