At present, when an automobile is produced and designed, in order to reduce the dead weight of the automobile body and save the cost, the automobile body covering piece is required to be made of non-metal materials so as to achieve the purposes of low cost and high yield, but the existing non-metal covering piece has the problems of excessive emission and serious pollution during production and processing, is seriously inconsistent with the national environmental protection concept, and causes the follow-up pollution improvement and treatment process and cost.
The design of hull part covering is mostly glass fiber products, easily causes certain influence to human body and environment among its product reproduction process. Particularly, the paint spraying treatment has the problems of excessive emission and serious pollution, does not accord with the national environmental protection concept seriously, and causes the subsequent pollution improvement and treatment process and cost.
However, some household appliances and household products are also painted and cannot meet certain requirements on flame retardance and corrosion resistance.
