Abstract
The invention belongs to the technical field of paint, and discloses thick-coating antirust asphalt paint, and a preparation method and application thereof. The asphalt paint comprises anionic emulsified asphalt, organosilicon modified self-crosslinking acrylic emulsion, chloroether emulsion and water; the preparation method for preparing the anionic emulsified asphalt comprises the following steps: mixing water, an emulsifier, and a thickener to form a soap solution mixture; heating and melting petroleum asphalt, adding the soap solution mixture, mixing, and grinding to obtain the anionic emulsified asphalt. The asphalt paint can be thick-coated, and the thickness of a formed dry paint film is not less than 170 mu m, for example 170-210 mu m, and the dry paint film has good adhesive force, excellent flexibility, impact resistance, corrosion resistance and high and low temperature resistance.
Description
Technical Field
The invention belongs to the technical field of paint, and particularly relates to thick-coating antirust asphalt paint, and a preparation method and application thereof.
Background
The prior art container coating is mostly organic solvent type coating, calculated according to the production amount of 250 tens of thousands of standard containers per year, and after the container coating is watered, the VOC (volatile organic compound) emission can be reduced by 10 tens of thousands of tons per year.
In the process of coating the container underframe, most of the requirements are that asphalt paint is further coated on the basis of the epoxy zinc-rich paint priming. The construction of the water-based asphalt paint in the prior art has certain limitation, and when the single-pass wet film is coated, a large-scale pinhole, sagging and dripping easily occur, and the formed coating has poor adhesive force, high and low temperature resistance, flexibility and the like. The film thickness of the dry film 170 μm which does not meet the standard requirement is not good because the film cannot be coated thickly, and the anti-corrosion performance is also poor. Because of the incapability of thick coating and slow drying speed, many factories have no organic solvent type asphalt paint for naphthalene in winter, which greatly increases the atmosphere pollution and the potential safety hazard in construction.
Therefore, it is needed to provide a water-based asphalt paint which can be thick coated and has good corrosion resistance, and the adhesion, high and low temperature resistance and flexibility of the formed coating are further improved.
Disclosure of Invention
The present invention aims to solve at least one of the technical problems in the prior art described above. Therefore, the invention provides the thick-coatable antirust asphalt paint, the preparation method and the application thereof, and the asphalt paint is water-based asphalt paint, and has the advantages of thick coating, good corrosion resistance, quick drying and further improved adhesive force, high and low temperature resistance and flexibility of a formed paint film.
The invention is characterized in that: the asphalt paint contains the anionic emulsified asphalt, the organosilicon modified self-crosslinking acrylic emulsion, the chlorohydrin emulsion and the water, and has the characteristics of moderate hardness, difficult stickiness at high temperature, difficult cracking at low temperature and high storage stability; the chlorohydrin emulsion has quick drying and excellent permeation resistance, so that water vapor is not easy to reach a substrate; the organosilicon modified self-crosslinking acrylic emulsion has excellent film forming property, and a dried paint film has excellent hydrophobicity.
