Antibiotic mildew-resistant algae-resistant anticorrosion paint and its uses

Abstract

The invention relates to a functional-form anticorrosion paint for conduits to raw water and drink water, and pipe inner wall, which comprises: curing agent, and main agent composed of epoxy resin, nano paint filler, nano inorganic antibiotic fungus-proof agent and organic solvent. This product inhibits the growth of hydrobiont, satisfies national standard with antibiotic ratio more than 99% and fungus-proof anti-algae grade all 0 grades, and belongs to green product.

Description

technical field

[0001] The invention relates to an anti-corrosion paint and its application, in particular to a functional anti-corrosion paint and its application. Background technique

[0002] For a long time, anti-corrosion coatings have been widely used in various fields of the national economy as a simple and effective anti-corrosion method. However, with the development of modern industry, the emergence of a number of emerging fields and the construction of many modern projects have put forward higher requirements for the functionality of anti-corrosion coatings. Commonly used anti-corrosion coatings can no longer meet these needs.

[0003] At present and in the next ten years, my country will implement a large-scale direct drinking water project, that is, the water plant will further purify the tap water, and transport it to the residential water point through a special water delivery pipeline, and its water quality index will reach the standard for direct drinking. ...

Examples

Embodiment 1

[0015]1. The components of the coating in this embodiment include a main agent and a curing agent. The epoxy resin in the main agent is epoxy resin E-44, and the nano pigments and fillers in the main agent are the above-mentioned titanium dioxide, precipitated silica, and talcum powder and fumed silica, the nano-inorganic antibacterial, mildew-proof and anti-algae agent in the main agent is the above-mentioned nano-composite inorganic antibacterial and algicide (and nano-organic silver-loaded antibacterial agent, the organic solvent in the main agent is ethanol; the curing agent is poly Amide curing agent 650. The corresponding weight ratio (expressed in parts by weight) of each component is shown in Table 1 (the symbol " / " in the table means none).

[0016] 2. The preparation method of the main agent. Add epoxy resin E-44 and ethanol to the reaction kettle according to the above weight ratio in a room with an ambient temperature of 5-50°C, and make epoxy resin E-44 under the ...

Embodiment 2 to Embodiment 48

[0022] The numerical value of the component of the coating of embodiment 2 to embodiment 48 and corresponding weight ratio (expressed in parts by weight) is shown in table 1 to table 8, and preparation method is basically the same as embodiment 1, and the impact resistance of coating is 50kgf cm, the flexibility is 0.5mm, the anti-mildew and anti-algae grades are both grade 0, the adhesion of the paint (pull-off method), the antibacterial rate against Escherichia coli and Staphylococcus aureus, and the dry film thickness of the paint once applied See Tables 1 to 8.

Embodiment 49

[0024] According to the use of one of the embodiments 1 to 12, this embodiment specifically applies the paint of one of the embodiments 1 to 12 to cover the inner wall of the pipeline respectively. The pipeline is a direct drinking water pipeline, a tap water pipeline or a raw water pipeline. For the pipelines, these pipelines have antibacterial, anti-mildew, anti-algae and anti-corrosion effects, and also have the effect of inhibiting bloodworms, freshwater shell vegetables and shellfish aquatic organisms.
