Example Embodiment

[0054] Correspondingly, the present invention also provides a preparation method of the above-mentioned waterproof algae coating composition, including:

[0055] After mixing 20-50 parts by weight of epoxy resin and 5-15 parts by weight of reactive diluent, add 3-5 parts by weight of dispersant, 4-6 parts by weight of thickener, and 10-15 parts by weight of Extender pigments, 30-40 parts by weight of water-absorbing pigments, and 10-20 parts by weight of algae-killing pigments are dispersed at high speed, and 5-15 parts by weight of microencapsulated modified phenalkamine curing agent are added and dispersed at low speed to obtain waterproof algae paint combination.

[0056] Among them, the microencapsulated phenalkamine modified curing agent is preferably prepared according to the following method:

[0057] Dissolving the modified phenalkamine curing agent in an organic solvent to obtain a modified phenalkamine curing agent solution;

[0058] Adding a polymethyl methacrylate solutio...

Example Embodiment

[0075] Example 1

[0076] The components of the waterproof algae paint are as follows:

[0077] 40 parts of hydrophobic epoxy resin, 1 part of defoamer, 3 parts of wetting and dispersing agent, 6 parts of thickener, 10 parts of active diluent, 7 parts of extender pigment, 8 parts of algae-killing pigment, 15 parts of water-absorbing pigment, micro 10 parts of encapsulated modified phenalkamine curing agent.

[0078] The preparation method of waterproof algae paint is as follows:

[0079] First add hydrophobic epoxy resin and reactive diluent, while stirring, add wetting and dispersing agent, defoamer, thickener, extender pigment, water absorbing pigment, algae-killing pigment, and disperse at high speed, then reduce the dispersion speed. And slowly add the microencapsulated modified phenalkamine curing agent to disperse uniformly at low speed.

[0080] Brush or roll the waterproof algae paint prepared in this embodiment directly on a clean cement wall. A small amount of water is allow...

[0081] Example 2

[0082] The components of the waterproof algae paint are as follows:

[0083] 20 parts of hydrophobic epoxy resin, 4 parts of wetting and dispersing agent, 4 parts of thickener, 12 parts of active diluent, 8 parts of extender pigment, 10 parts of algae killing pigment, 37 parts of water-absorbing pigment, microencapsulated modified phenalkamine 5 parts of curing agent.

[0084] The preparation method of waterproof algae paint is as follows:

[0085] First add hydrophobic epoxy resin and reactive diluent, while stirring, add wetting and dispersing agent, thickener, extender pigment, water-absorbing pigment, algae-killing pigment, and disperse at high speed, then reduce the dispersion speed and add slowly The microencapsulated modified phenalkamine curing agent is uniformly dispersed at low speed.

[0086] Brush the finished paint evenly on the glutinous rice paper for use.

[0087] The paint prepared in this embodiment can be directly operated with water, and the gluti...

Abstract

The invention provides an algae-proof coating composition and a preparing process thereof. The algae-proof coating composition includes 20 to 50 parts by weight of epoxy resin, 5 to 15 parts by weight of active diluents, 5 to 15 parts by weight of microcapsulation phenolic amine modified curing agents, 3 to 5 parts by weight of dispersing agents, 4 to 6 parts by weight of thickening agents, 10 to 15 parts by weight of extender pigment, 10 to 20 parts by weight of algae-removing pigment and 30 to 40 parts by weight of water absorption pigment. Compared with the existing single-component algae-proof coating, the algae-proof coating is low in content of organic solvents and good in environmental protection, and can achieve the standard of direct contact with drinking water; compared with the existing double-component algae-proof coating, the algae-proof coating only need stir and then coat without blending before using, and is capable of being performed in underwater operation and applicable for being used in drinking water pipes.

Description

technical field [0001] The invention relates to the field of algae prevention and control, in particular to a waterproof algae coating composition and a preparation method thereof. Background technique [0002] Paint is a chemical product made of resin and oil, with or without pigment. Applying the paint on the surface of the object can dry and form a film, which isolates the surface of the coated object from the environmental medium, thus playing a role of protection and decoration for the coated object. According to different functions, coatings include: decorative coatings, anti-corrosion coatings, heat-insulating coatings and fire-resistant coatings. In recent years, with the construction of many modern projects, the application of anti-corrosion coatings has become more and more extensive. [0003] Waterproof algae paint is an important class of anti-corrosion paint, its main function is to prevent algae from attaching and growing on the surface of objects. The water...
