Abstract

The invention belongs to the technical field of coating liquid preparation, and particularly relates to a preparation method and application of a coating liquid. In the preparation method, the compatibility of the modified titanium dioxide particles with an organic polymer material is improved; the zinc stearate is beneficial to reducing the friction coefficient of the coating and plays a lubricating role; the composite emulsion formed by the monomer and the titanium dioxide is beneficial to improving the thermoplasticity, toughness, creep resistance and chemical resistance of the coating, when the coating liquid is coated on the film, the problem of adhesion between the films is not easy to occur, and the films are not easy to break; a coating formed by the coating liquid prepared by thepreparation method provided by the invention can simultaneously have the advantages of an organic material and an inorganic material.

Description

technical field [0001] The invention belongs to the technical field of coating liquid preparation, and in particular relates to a preparation method and application of a coating liquid. Background technique [0002] The traditional film uses gelatin as the film-forming material of the photosensitive layer and the auxiliary layer. Hydrophilic gelatin as the emulsion carrier has defects such as strong water absorption, large hygroscopic expansion coefficient, high elastic modulus, and low mechanical strength. Poor stability, easy to curl, easy to break at low temperature and low humidity. At the same time, during storage and transportation, the high temperature and high humidity environment will easily cause adhesion and texture between the films. In severe cases, the emulsion layer will be destroyed, affecting the production and use of the film. Static electricity is generated when the film is separated, causing the film to form watermarks, purple spots, and textures, resulti...
