Abstract
The invention discloses a kind of aqueous double-component epoxy coating, including following components and weight fraction：Aqueous epoxy resins, waterborne curing agent, biocide mildewcide, anti-settling agent, auxiliary rheological agents, dispersant, coalescents, extender pigment, rust resisting pigment, water.The present invention has good filming performance, reaches national requirements for environmental protection, is effectively improved the painting environment of workmen, and can adjust the coating open hour, adapts to duration demand.
Description
Technical field
The invention belongs to anticorrosive paint field, and in particular to a kind of aqueous double-component epoxy coating.
Background technology
Epoxy resin is a kind of important thermosetting resin kind.It has excellent physical and mechanical properties, electrical insulating property
Energy, resistance to chemical corrosion, heat-resisting and adhesive property.Therefore, research and development novel environment friendly, the water-base epoxy antirust of excellent performance
Coating meets the trend of current paint development.
World's aqueous epoxy resins production development is very fast, and global epoxy resin annual production at the beginning of 21 century has made a call to 1,500,000 tons, and
To be not less than 5% speed sustainable growth every year.
In recent years.The law of relevant environmental pollution limitation is put into effect in succession with regulation, is directed to just having to coating industry
VOCs (content of organic volatile in coating) and HAPs (pollutant in noxious air) discharge two large problems.Developed for this
Aqueous epoxy resins have become the common recognition of coating industry.Not only VOC content is low for waterborne epoxy coatings, and smell is smaller, makes
Directly it can be cleaned with safety and with water, technology is increasingly mature.
The content of the invention
The purpose of the present invention, exactly in order to solve the above problems and there is provided a kind of aqueous double-component epoxy coating and
Its preparation method, with good filming performance, reaches national requirements for environmental protection, is effectively improved the painting environment of workmen, and
And the coating open hour can be adjusted, adapt to duration demand.
The object of the present invention is achieved like this：
A kind of aqueous double-component epoxy coating of the present invention, including component and parts by weight once：
The present invention also provides a kind of preparation method of aqueous double-component epoxy coating, comprises the following steps：
(1) raw material is prepared by following components and weight fraction：
(2) aqueous epoxy resins, water 5-10%, bactericide, anti-settling agent, dispersant, coalescents, extender pigment and antirust
Pigment, be uniformly dispersed, be then ground to 30 microns it is standby；
(3) waterborne curing agent, water 5-10%, defoamer are uniformly dispersed, it is standby；
(4) before construction, the mixture in mass ratio 5 that will be obtained in step (2) and step (3)：1 is well mixed.
The present invention has good filming performance, reaches national requirements for environmental protection, is effectively improved the painting environment of workmen,
And the coating open hour can be adjusted, adapt to duration demand.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
The raw material information and Example formulations that the embodiment of the present invention is used are as shown in table 1.
Raw material information and formula that the embodiment of table 1 is used
Preparation method is as follows：
(1) aqueous epoxy resins, water, each analog assistant and all kinds of pigment are formulated by component A, are uniformly dispersed, are then ground to
30 microns standby；
(2) waterborne curing agent, water, each analog assistant are formulated by component B, are uniformly dispersed, it is standby；
(3) before construction, the mixture in mass ratio 5 that will be obtained in step (2) and step (3)：1 is well mixed.
Embodiment performance test methods, standard and result are as shown in table 2：
The embodiment performance test methods of table 2, index and result
Filming performance of the present invention is good from the point of view of the present embodiment test result, meets the environmental requirement of country.
Above example is used for illustrative purposes only, rather than limitation of the present invention, about the technology people of technical field
Member, without departing from the spirit and scope of the present invention, can also make various conversion or modification, therefore all equivalent
Technical scheme should also belong to scope of the invention, should be limited by each claim.
