Problems solved by technology

Oil-based antirust paint makes it difficult to remove the greasy surface of the material, so it is rarely used
Water-based anti-rust paint is easy to use and low in price, but because it contains toxic substances such as nitrite and chromate, it is very harmful to operators, the country has restricted its use, and this kind of product has single performance

Embodiment 1

[0017] A composite antirust coating, in parts by weight, is composed of the following substances:

[0018] Styrene-acrylic emulsion: 30, formaldehyde resin: 10, talc: 10,

[0019] Zinc oxide: 3, barium sulfate: 3, titanium dioxide: 10,

[0020] Sodium tosylate: 1, Glycol: 5, Polyacrylamide: 1,

[0021] Water: 60.

[0022] In the above technical scheme, the preparation process of the composite anti-rust coating is as follows:

[0023] (1) Add water, styrene-acrylic emulsion, formaldehyde resin, zinc oxide, barium sulfate and titanium dioxide to a container with a stirrer, mix thoroughly, put it into a grinder and grind to obtain a white powder with a fineness of less than 50 microns. slurry;

[0024] (2) After mixing the prepared white slurry with other components, stir well, and filter to obtain the finished product.

Embodiment 2

[0026] A composite antirust coating, in parts by weight, is composed of the following substances:

[0027] Styrene-acrylic emulsion: 50, formaldehyde resin: 20, talc: 20,

[0028] Zinc oxide: 5, barium sulfate: 5, titanium dioxide: 20,

[0029] Sodium tosylate: 3, Glycol: 8, Polyacrylamide: 3,

[0030] Water: 100.

[0031] The preparation process is the same as that in Example 1.

Embodiment 3

[0033] A composite antirust coating, in parts by weight, is composed of the following substances:

[0034] Styrene-acrylic emulsion: 40, formaldehyde resin: 16, talc: 16,

[0035] Zinc oxide: 4, barium sulfate: 4, titanium dioxide: 16,

[0036] Sodium toluenesulfonate: 2, Glycol: 6, Polyacrylamide: 2,

[0037] Water: 80.

[0038] The preparation process is the same as that in Example 1.

[0039] Product application: Although this product is an anti-rust coating, in order to ensure the quality of the rusted coating, the loose floating rust, oil stain, impurities and oxide scale should be removed before construction. Can fully penetrate deep into the rust layer. The construction method is better by brushing.

Abstract

The invention discloses a composite antirust paint. The composite antirust paint comprises components in parts by weight as follows: 30-50 parts of styrene acrylic emulsion, 10-20 parts of formaldehyde resin, 10-20 parts of talcum powder, 3-5 parts of zinc oxide, 3-5 parts of barium sulfate, 10-20 parts of titanium dioxide, 1-3 parts of sodium benzenesulfonate, 5-8 parts of ethylene glycol, 1-3 parts of polyacrylamide and 60-100 parts of water. Compared with a prior art, the composite antirust paint provided by the invention is the composite antirust paint for permeable rust; mainly using composite resin with strong permeability as a main film forming matter and being assisted by other auxiliary agents, the coated composite antirust paint penetrates into a rust layer to isolate the rust from outer media so as to achieve the antirust purpose. The composite antirust paint provided by the invention has the advantages of good antirust effect, simple preparation process and cheap price.

Description

technical field [0001] The invention belongs to the technical field of building decoration materials, and more particularly relates to a composite antirust coating. Background technique [0002] Metal surfaces are prone to rust due to prolonged exposure to air, therefore, anti-rust treatment is required. At present, the common practice is to brush a layer of anti-rust paint on the metal surface to prevent rust. [0003] The anti-rust paints currently used are roughly two types: oil-based anti-rust paint and water-based anti-rust paint. Oil-based anti-rust paint makes it difficult to remove the greasy surface of the material and has been rarely used. Water-based anti-rust paint is easy to use and low in price, but because it contains toxic substances such as nitrite and chromate, it is harmful to operators. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a composite anti-rust paint. [0...
