Description
Technical Field
The invention relates to a window film suitable for being adhered to the surface of window glass of a building or window glass of an automobile, in particular to a bacteriostatic explosion-proof window film with a bacteriostatic coating.
Background
Based on the requirement of explosion prevention, the glass surface of doors and windows of vehicles and buildings is usually stuck with an explosion-proof window film. However, once the window film is bred with bacteria, the environment in a vehicle or an indoor environment is inconvenient for health life, and in general, ordinary people can not pay attention to the problem that whether the window film has the bacteria, so that the breeding of the bacteria in the window film can form a pollution source which is difficult to find, and the pollution is a great hidden danger. The antibacterial coating is coated on the surface of the window film, so that the growth of bacteria on the window film can be inhibited, and the propagation of the bacteria can be effectively prevented.
The common bacteriostatic coating is formed by adding bacteriostatic agent on the basis of common coating and coating the bacteriostatic agent on the surface of a window film for curing. The bacteriostatic agent is used as a functional auxiliary agent to be dispersed in a coating system and exists in the coating after being cured. The bacteriostatic agent can be organic bacteriostatic agent or inorganic bacteriostatic agent. The bacteriostatic agent serving as the functional auxiliary agent has a common defect that the binding force with other components of common coatings is not enough, particularly, inorganic bacteriostatic agents can migrate to the surface of a coating along with the lapse of time, and the bacteriostatic agent is lost by wiping the surface of the coating, so that the bacteriostatic ability is attenuated, and even the bacteriostatic ability is lost.
The organic bacteriostatic agent is divided into two types of organic small-molecular bacteriostatic agents and high-molecular bacteriostatic agents, which are various, and mainly comprises vanillin or ethyl vanillin compounds, acylanilines, imidazoles, thiazoles, isothiazolone derivatives, quaternary ammonium salts, quaternary phosphonium salts, biguanidine compounds, phenols and the like, and also comprises chitin, mustard, castor oil, horseradish and other natural bacteriostatic agents. The organic small molecular bacteriostatic agent is easy to volatilize, has poor chemical stability, poor compatibility with base materials and difficult dispersion in the base materials. Another significant disadvantage of organic bacteriostats is their poor thermal stability and unsuitability for high temperature thermal curing applications.
The inorganic bacteriostatic agent is prepared by fixing metals (or ions thereof) such as silver, copper, zinc and the like on the surface of porous materials such as fluorite, silica gel and the like by utilizing the bacteriostatic ability of the metals such as silver, copper, zinc and the like and corresponding metal ions through methods such as physical adsorption, ion exchange and the like, and then adding the bacteriostatic agent into a coating system, and of course, metal powder such as silver, copper, zinc and the like and corresponding inorganic salt powder can also be directly added into the coating. The bacteriostatic agent is commonly used as silver-loaded zeolite, silver-loaded zinc zeolite and the like, and the main bacteriostatic factor is silver ions or silver. The other inorganic bacteriostat, such as nano titanium dioxide, can be directly added into the coating system to play a role in bacteriostasis. The inorganic bacteriostatic agent has the advantages of good heat stability, wide spectrum bacteriostasis, high bacteriostasis efficiency and difficult generation of drug resistance, and can be applied to baking type coatings; the disadvantages are that silver ions or silver is easy to discolor and is not suitable for light-colored paint; the nano titanium dioxide can exert bacteriostatic activity only by illumination, and atomic oxygen decomposed under illumination can decompose coating resin to cause the deterioration of coating performance; another significant drawback is the aforementioned migration to the surface of the coating over time, attenuation of the bacteriostatic ability and even loss of the bacteriostatic ability.

As described in the background section, in view of the defect that the bacteriostatic coating in the prior art is easy to discolor due to the use of an inorganic bacteriostatic agent, the application of the bacteriostatic coating to a window film is easy to reduce the use appearance, so that the invention provides a bacteriostatic and explosion-proof window film with a bacteriostatic composition, wherein the bacteriostatic composition contains an organic bacteriostatic agent, and in order to avoid the defect of poor thermal stability of the organic bacteriostatic agent, the bacteriostatic composition is cured by means of UV irradiation at a lower temperature, so that the bacteriostatic coating with the thickness of 4-12 μm can be formed to provide a lasting bacteriostatic effect, and the bacteriostatic coating has excellent wear resistance and antifouling effect.
