Abstract
The utility model relates to a rust-preventing film having a heat insulation function, which comprises a VCI (volatile corrosion inhibitor) gas-phase rust-preventing film, wherein the upper layer and the lower layer of the VCI gas-phase rust-preventing film are respectively coated with a chemical conversion layer; and each chemical conversion layer is coated with a heat insulation layer. The rust-preventing film having a heat insulation function has the heat insulation layers on the surfaces, and the heat insulation layers are made of polyester, have high toughness and are matched with the chemical conversion layers, thus ensuring that a constant-temperature state is kept between the rust-preventing film and a workpiece and the rust-preventing effect is more stable, and prolonging the service life of the rust-preventing film.
Description
Technical field
The utility model belongs to the packaging film field, relates to rust-preventing film, especially a kind of rust-preventing film with heat insulating function.
Background technology
That the VCI gas phase anti-tarnishing film uses is simple, save time, saving of labor, clean, dry, antistatic, no burn into rust-proof life limit for length, rust-proof effect are remarkable, to environment and human body nonhazardous, be widely used in electronic product, component of machine, the vapour fields such as assembly, electronic apparatus, hardware, war industry equipment, sheet material wire rod, tool and mould, instrument and meter, gold-silver ornaments of rubbing, portioned product has entered industries such as Chinese military project, aviation, railway, automobile, shipbuilding, electronics now.Its duty is, when the concentration of inhibition molecule in the environment was low, rust-preventing film was volatilized automatically, and the corrosion inhibiter molecular concentration increases gradually in the system, and when reaching the volatilization balance, the corrosion inhibiter molecular concentration reaches maximum in the system, at this moment rust-proof effect the best; Along with the variation between very little, the corrosion inhibiter volatility in the rust-preventing film begins to descend, when volatility less than the packaging material loss or when consuming, gas phase anti-tarnishing film just can not effectively suppress to invade causes the erosion molecule, loses antirust ability.
But be placed on sometimes in the higher zone of temperature in transportation or use by the workpiece that rust-preventing film wraps, though the rust-proof effect of rust-preventing film can promote along with the rising of temperature because of the antirust material of VCI, but deformation then can take place in rust-preventing film self under the environment of excessive temperature, thereby has influenced service life or the result of use of rust-preventing film; Correspondingly with it be, if place the lower zone of temperature not only can cause the result of use of rust-preventing film to reduce the workpiece that wraps, rust-preventing film self is become fragile and produce be full of cracks, influenced the service life of rust-preventing film thus.
Summary of the invention
The purpose of this utility model is to overcome the prior art deficiency, and a kind of rust-preventing film with heat insulating function is provided, and this rust-preventing film can keep the constant of temperature in the uniform temperature interval, can not influence the rust-proof effect of self because of the cataclysm of ambient temperature.
The technical solution adopted in the utility model is:
A kind of rust-preventing film with heat insulating function comprises the VCI gas phase anti-tarnishing film, is coated with a chemical conversion layer respectively on the upper and lower surface of VCI gas phase anti-tarnishing film, is coated with a thermal insulation layer on every stratification conversion coating.
And described thermal insulation layer is made by polyester.
The utility model advantage and good effect are:
Originally the rust-preventing film that has heat insulating function is provided with thermal insulation layer from the teeth outwards, this thermal insulation layer is made by polyester, it has very strong toughness, and fiting chemical conversion coating, guaranteed the temperature constant state between rust-preventing film and the workpiece thus, rust-proof effect is more tended towards stability, also prolonged the service life of rust-preventing film simultaneously.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Fig. 3 is the B part enlarged diagram of Fig. 2.
The specific embodiment:
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of rust-preventing film with heat insulating function, comprise the VCI gas phase anti-tarnishing film, be coated with a chemical conversion layer 2 respectively at VCI gas phase anti-tarnishing film upper and lower surperficial 3, be coated with a thermal insulation layer 1 on every stratification conversion coating, chemical conversion layer is bonded on the rust-preventing film anti oxidation layer better, assists and has improved antirust film strength.
This thermal insulation layer is made by polyester, has very strong toughness, and the fiting chemical conversion coating, has guaranteed the temperature constant state between rust-preventing film and the workpiece thus, and rust-proof effect is more tended towards stability, and has also prolonged the service life of rust-preventing film simultaneously.
