Cleaning-free external pasting film

Abstract

A cleaning-free external pasting film is composed of a basal layer, a glue layer and a film layer, wherein the basal layer is made of a smooth synthetic papers surface coating silicon oil layer with toughness; the film layer is made by dissolving 35 shares of HO-(CH2CH2O)18-COOH and 10 shares of EuCl2 6H2O into methanol to mix, a [HO-(CH2CH2O)18-COO]2Eu complexes is obtained through oil bath heating, inverse flow, filtrating, decompression rotary evaporation to remove dissolvent and cooling, then the film layer will be obtained by adding the complexes into polyethylene; for the glue layer, a suspending liquid is obtained by agitating 50 shares of graphite and 200 shares of N-2-hydroxyethylamino; a glue is obtained by agitating a mixture of 1 shares of the suspending liquid and 49 shares of polyurethane glue by weight, the glue layer will be obtained by jetting the glue on the film layer. The pasting film of the invention is economic and environment protection, operation is easy and safe. The film has characteristics of colorless transparent, water-proof, oil-proof, sun-prevention, high temperature resistant, chilliness resistance and easy operation, the glue may be applied at a temperature range from -30 DEG C to 110 DEG C, and it is capable of resisting summer sweltering high-temperature and winter chilliness low-temperature.

Description

technical field [0001] The invention relates to the technical field of external protective films for mechanical equipment, means of transportation and other supplies, in particular to a non-cleaning outer film pasted on the outer surfaces of mechanical equipment and means of transport. Background technique [0002] In recent years, the machinery manufacturing industry has developed rapidly, and a large number of mechanical equipment and transportation tools of various models, styles, and functions have been continuously put into the market and used in various fields. During the use of these machines, due to the effect of wind and rain, the appearance of the mechanism equipment and means of transportation that work or operate in the open air will be damaged, and even the function of the equipment will be affected. For example, running cars, trains, construction machinery and equipment will be affected by wind and rain or sandstorms, and the appearance will be damaged to a cer...

AI Technical Summary

Problems solved by technology

During the use of these machines, due to the effect of wind and rain, the appearance of the mechanism equipment and means of transportation that work or operate in the open air will be damaged, and even the function of the equipment will be affected.

For example, running cars, trains, construction machinery and equipment will be affected by wind and rain or sandstorms, and the appearance will be damaged to a certain extent. The cleaning and maintenance of the above-mentioned equipment in the case of a very scarce situation will accelerate the shortage of water resources. At the same time, it will also block municipal facilities such as sewer pipes in urban and rural areas, causing new pollution and directly affecting the living environment of residents.

Moreover, the direct contact of water with the metal on the outer surface of the equipment will cause oxidation and corrosion of the metal and shorten the service life of the equipment.

In addition, agricultural mulch is widely used at present. Since the mulch currently sold in the market and used by farmers does not have the degradation function, it will cause a lot of white pollution after use.
