Abstract
The invention belongs to the field of electric materials and discloses a preparation process of degradable packaging plastic used for an electric system. The preparation process comprises the following steps: (1) weighing raw materials; (2) centrifuging and stirring; and (3) melting and de-molding. The preparation process has the advantages of being simple and feasible, the machinery performance of the prepared plastic is good, the degradation degree is high and the pollution to the environment is greatly reduced.
Description
Technical field
The invention belongs to electric power Material Field, be specifically related to a kind of preparation technology for power system degradable package plastics.
Background technology
The outer packaging such as cable and electrical equipment adopts lightweight plastic material mostly, in order to avoid damaged or corrosion etc.After dress plastic material to be outsourced is removed, great majority as waste refuse treatment, easily cause environmental pollution everywhere.At present, housing material is Plastic Packaging Materials mostly.Vinyon packing articles in plastic material, belongs to non-returnable container articles for use, cheap, is widely used in daily life.Be worth owing to there is no to recycle, the rate of recovery is extremely low, and because its light weight and the characteristic being difficult to degrade cause with wind drift, contaminated land and the water surface, account for the chief component in the established white garbage of China.
In the research process seeking the pollution of degradable plastics solution plastic garbage, the biodegradable plastic that raw material obtains based on starch obtains and develops rapidly.In bio-degradable plastics, this natural high molecular substance of starch has wide material sources, cheap, the regeneration period is short, can in a variety of contexts complete biodegradable, the advantages such as any pollution can not be produced to environment, be the good natural biological degradable material of development prospect.But mechanical property and the elastic performance of pure starch plastics are lower, and product is heavier, make it apply and are greatly limited.
