Abstract
The application relates to the field of finish paint materials, and particularly discloses a color chlorinated rubber finish paint and a preparation method thereof. The color chlorinated rubber finishing paint comprises the following raw materials in parts by weight: 19-21 parts of chlorinated rubber, 27-32 parts of solvent, 8-13 parts of chlorinated paraffin, 0.3-0.8 part of dispersing agent, 23-25 parts of titanium pigment, 0.01-0.03 part of pigment and 10-20 parts of filler, wherein the chlorinated paraffin is a mixture of chlorinated paraffin-70 and chlorinated paraffin-52. The color chlorinated rubber finishing paint has excellent flexibility under the mutual compounding action of chlorinated paraffin-70 and chlorinated paraffin-52, and reduces the phenomena of easy embrittlement and cracking of a paint film.
Description
Technical Field
The application relates to the field of finish paint materials, in particular to a color chlorinated rubber finish paint and a preparation method thereof.
Background
The chlorinated rubber is a rubber derivative obtained by chloridizing and modifying natural rubber or synthetic rubber, and is the 1 st industrialized rubber derivative in the rubber field. The chlorinated rubber finishing paint consists of chlorinated rubber, pigment and filler, and is quick in paint film drying, and because chlorine element is introduced, a C-Cl bond with larger polarity is formed, and the chlorinated rubber finishing paint has excellent weather resistance, water and mildew resistance and chemical resistance.
However, the paint film formed by the chlorinated rubber finish paint is brittle, and the surface of the paint film is easy to be chalked and cracked after a long time, so that the service life of the paint film is influenced.
Disclosure of Invention
In order to improve cracking and chalking of chlorinated rubber finishing paint, the application provides a color chlorinated rubber finishing paint and a preparation method thereof.
In a first aspect, the application provides a color chlorinated rubber finishing paint, which adopts the following technical scheme:
the color chlorinated rubber finishing paint comprises the following raw materials in parts by weight: 19-21 parts of chlorinated rubber, 27-32 parts of solvent, 8-13 parts of chlorinated paraffin, 0.3-0.8 part of dispersing agent, 23-25 parts of titanium pigment, 0.01-0.03 part of pigment and 10-20 parts of filler, wherein the chlorinated paraffin is a mixture of chlorinated paraffin-70 and chlorinated paraffin-52.
By adopting the technical scheme, the chlorinated paraffin is added into the finish paint system, so that the flexibility of the chlorinated rubber finish paint can be improved, the brittleness of a paint film is reduced, the phenomena of stretching and cracking which are easy to occur in the paint film are reduced, and the flexibility and impact resistance of the paint film are improved. The No. 70 chlorinated paraffin can improve the flame retardant property of the chlorinated rubber finishing paint, the No. 52 chlorinated paraffin has better compatibility and heat resistance, and the No. 52 chlorinated paraffin and the No. 70 chlorinated paraffin are compounded to promote the chlorinated rubber finishing paint to have better heat resistance and flame retardant property and flexibility.
The titanium dioxide has high refractive index, strong tinting strength and good dispersibility, and plays roles of increasing color and improving brightness in chlorinated rubber finishing paint after being mutually blended with pigment. The titanium dioxide also has excellent ultraviolet resistance, can improve the light aging resistance of the chlorinated rubber finish paint, and reduces the phenomena of light loss and chalking of the finish paint.
Preferably, the filler comprises the following raw materials in parts by weight: 1-2 parts of organic bentonite, 3-8 parts of talcum powder and 5-11 parts of precipitated barium sulfate.
By adopting the technical scheme, the organic bentonite is more suitable for solvent-type chlorinated rubber finishing paint, improves the impact resistance and hardness of a chlorinated rubber finishing paint film, can promote each component in a finishing paint system to have certain viscosity, and can form hydrogen bonds with anti-settling effect by oxygen and hydroxyl groups of the organic bentonite, so that the settling phenomenon of pigment, filler and other component particles in the finishing paint system is reduced.

As shown by the performance detection result, the color chlorinated rubber finishing paint prepared by the application has excellent impact resistance and adhesion. Meanwhile, the formed paint film has better flexibility, and the phenomenon that the paint film is easy to crack and damage is reduced.
In examples 1-8, the color chlorinated rubber finishing paint has different contents of each component, wherein the comprehensive performance of example 1 is better, and the 70 # chlorinated paraffin and the 52 # chlorinated paraffin are compounded with each other, so that the paint film has good flexibility, and the phenomena of easy cracking and stretching of the paint film are reduced.
In examples 9-12, proper amounts of defoamer, rheology aid and leveling agent are added to the color chlorinated rubber top-coat, and the performance test results show that the color chlorinated rubber top-coat has improved comprehensive performance, improved impact resistance and adhesion, and better dispersibility of each component in the color chlorinated rubber top-coat system.
In examples 13 to 15, a proper amount of epoxy resin was added to the colored chlorinated rubber topcoat, and it was found from the results of performance test that the adhesion of the colored chlorinated rubber topcoat to the substrate was significantly enhanced, and at the same time, the film forming property of the topcoat was enhanced, and the impact resistance of the topcoat was also improved by the cross-linking of the epoxy resin with the chlorinated rubber.

As is clear from comparison of comparative examples 1 and 2 with example 1, comparative example 1 does not use chlorinated paraffin, and the formed paint film is brittle, is liable to crack and deform, and is low in impact resistance. The color chlorinated rubber finishing paint prepared in comparative example 2 has certain flexibility, but the comprehensive performance of example 1 is better because the chlorinated paraffin 52 and the chlorinated paraffin 70 are compounded, so that the chlorinated rubber finishing paint has excellent flexibility when the temperature is changed, and the service life of the chlorinated rubber finishing paint is prolonged.
