preparation example Construction

[0048] The preparation method of this coating comprises the steps:

[0049] In the first step, the modified graphene, titanium dioxide and talc powder are sequentially added to the modified acrylic emulsion, the temperature is raised to 80-90°C, and the premix is ​​obtained at a high speed of 800-1000r / min for 25-30min under constant temperature conditions. stop heating;

[0050] The second step, add the thickener, dispersant and coupling agent in the auxiliary agent to 1 / 3 volume of deionized water, stir and mix evenly, then add to the premix, disperse at 400-500r / min for 10-12min, Then add anti-rust additives and continue to disperse for 8-10 minutes;

[0051] In the third step, finally add film-forming aids and defoamers, add the remaining deionized water, disperse at 200-300r / min for 15-17min, and prepare the coating.

Abstract

The invention discloses an anticorrosive paint for building materials. The anticorrosive paint is prepared from the following raw materials in parts by weight: 40-50 parts of modified acrylic emulsion, 0.8-1 part of modified graphene, 9-13 parts of titanium dioxide, 8-10 parts of talcum powder, 1.2-1.6 parts of an antirust additive, 5-6 parts of an assistant and 20-30 parts of deionized water. Theinvention also discloses a preparation method of the anticorrosive paint. Modified acrylic emulsion is used as a film-forming substance of the paint, so that the paint not only has a good film-forming property and adhesive force, but also has excellent water resistance and aging resistance. By adding the antirust additive, an antirust effect can be achieved, and a corrosion inhibition function isachieved. Modified graphene is added to serve as an excellent shielding layer, so that the contact between building materials and a corrosive medium is prevented, and the corrosion resistance is enhanced. The paint is better combined with a matrix, and plays corresponding effects more easily. The aqueous anticorrosive paint has an excellent comprehensive performance and is suitable for protectingmetal building materials.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an anti-corrosion coating for building materials and a preparation method thereof. Background technique [0002] Building materials are a general term for materials used in civil engineering and construction engineering, including wood, concrete, composite materials, metal materials, etc. Among them, metal materials play an important role in building materials. However, the corrosion-prone characteristics of metal materials will affect the use effect of building materials. Therefore, the anticorrosion of metal building materials is particularly important. One of the current economical and applicable metal anti-corrosion methods is to add a layer of dense and stable coating on the metal surface to improve its corrosion resistance. [0003] The Chinese invention patent with the patent number CN201710950949.1 discloses an environmentally friendly anti-corrosion coating...
