preparation example Construction

[0029] A preparation method for graphene anticorrosion powder coating, comprising the following steps:

[0030] First, prepare the graphene additive, and stir and blend the graphene and epoxy resin to ensure that the mixing is fully uniform and dispersed;

[0031] Secondly, the components for preparing graphene are blended in proportion and then extruded;

[0032] Finally, tableting, grinding, and separation are carried out to obtain finished products.

Embodiment 1

[0035] A graphene anti-corrosion powder coating, consisting of the following components in terms of mass percentages: 28 parts of epoxy resin, 28 parts of polyester resin, 10 parts of titanium dioxide, 26 parts of barium sulfate, 5 parts of additives, 2 parts of graphene, 1 part of coloring material.

[0036] Stir and blend graphene and epoxy resin vigorously to ensure full uniformity and dispersion, and then carry out the preparation process of powder coatings, first perform blending and extrusion according to the above ratio, and then tablet, finely separate, inspect, measure, and package and other processes to obtain the finished graphene powder coating.

Embodiment 2

[0038] A graphene anti-corrosion powder coating, consisting of the following components according to mass percentage: 28 parts of epoxy resin, 28 parts of polyester resin, 26 parts of titanium dioxide, 10 parts of barium sulfate, 4 parts of additives, 2 parts of graphene, 2 parts of coloring material.

Abstract

The invention relates to a graphene anticorrosive powder paint which is composed of the following components in parts by weight: 25-70 parts of epoxy resin, 25-70 parts of polyester resin, 5-40 parts of titanium white, 5-40 parts of barium sulfate, 3-10 parts of assistant, 0.5-10 parts of graphene and the balance of other pigments. The powder paint has excellent anticorrosive property and favorable powdering penetrating power, and the surface scratch resistance is up to 2H above. The preparation technique is simple; the application technique is convenient; and the paint has excellent comprehensive properties.

Description

technical field [0001] The invention belongs to the field of coatings, and relates to an anti-corrosion powder coating and a preparation process thereof, in particular to a mixture of graphene, epoxy resin, polyester resin and the like. Background technique [0002] Metal corrosion not only brings economic losses to human beings, but also is not conducive to the protection of natural resources and the environment, and sometimes even endangers personal safety. In order to prevent and slow down corrosion, many anti-corrosion methods have been developed in production practice and scientific experiments. Among them, paint protection is the most convenient and economical, so it has been widely used. [0003] Chinese patent CN103589281A discloses an improved metal anti-corrosion coating, which consists of the following components in terms of mass percentage: 30-40 parts of GHNK high temperature resistant binder, 15-20 parts of polyaniline / graphene composite material, and coloring...
