Abstract
The present invention proposes a kind of anti-corrosion epoxy zinc rich primer and preparation method thereof, including component A and component B, it is characterised in that：Component A includes epoxy resin, high-purity zinc powder, environmentally friendly trbasic zinc phosphate, auxiliary agent A/B, organobentonite, mixed solvent；Component B includes modified by cardanol polyamide, auxiliary agent C and mixed solvent.The product of the present invention has salt spray resistance, a hyperbaric feature, and its amount of solid content, which reaches 95%, metal Zn content and reaches the solid proportion of 80%, paint, reaches 3.0g/ml, and salt spray resistance reaches that more than 5000 hours paint films are non-foaming, do not return rust, do not fall to paint.Such product can be widely used for weather more badly and on the metal heavy-duty product of coastal area, such as：The fields such as bridge, steel structure, ship, petroleum pipeline.
Description
Technical field
The present invention relates to epoxy zinc rich primer manufacturing field, particularly relates to a kind of anti-corrosion epoxy zinc rich primer and its preparation side
Method and preparation method thereof.
Background technology
The problem of metal erosion be that modern people face one is very serious, this problem is almost throughout social production
Every field.Due to corrosion, a large amount of hard-earned useful materials become waste material, cause protection to weaken, equipment failure, consumption
Resource also results in huge economic loss, also causes the problems such as environmental pollution indirectly.For a long time, people employ many
Technology is protected by metal, prevents from corroding, and one of most effective of which method is exactly to coat erosion shield in metal surface,
To completely cut off corrosive medium and metallic matrix.
Zinc-rich paint is a kind of anticorrosive paint of excellent anti-corrosion performance, has been widely used each neck of industrial antisepsis
Domain, it is divided into organic zinc-rich paint and inorganic zinc coating, and epoxy zinc-enriched paint is most important one kind in organic zinc-rich paint.
Because the electrode potential of zinc is less than the electrode potential of iron, therefore the zinc in epoxy zinc-enriched paint can play anode loss protection work
With the product after zinc powder is corroded in addition can fill the hole of film, close the damage location of film.So to a certain degree
On, the Zn content proportion in coating is higher, and its antiseptic property is better.But because technology and technique limit, existing zinc rich primer
Middle zinc content is typically below 80%, it is impossible to ensures between zinc powder and zinc powder is the same as the electric current transmission between ground.
In addition, under the high salt mist environment such as awful weather and coastal area, metal is more prone to be corroded, common antirust
Often duration is insufficient for the salt spray resistance of paint, it is difficult to meets equipment needs.As people are more next to metal heavy-duty technical requirements
On the premise of higher, a high specific gravity, high metal Zn content are developed in market in urgent need, and salt spray resistance is rich in the epoxy of routine
There is the novel environment-friendly epoxy zinc rich primer compared with quantum jump on yellow zinc chromate primer paint.
The content of the invention
The present invention proposes a kind of anti-corrosion epoxy zinc rich primer and preparation method thereof and preparation method thereof, can ensure that product is consolidated
Body divides content and metal Zn content to improve, and salt spray resistance duration extends.
The technical solution adopted in the present invention is：A kind of anti-corrosion epoxy zinc rich primer and preparation method thereof, including component A and
Component B, it is characterised in that：Component A includes epoxy resin, high-purity zinc powder, environmentally friendly trbasic zinc phosphate, auxiliary agent A/B, mixed solvent；Group
B is divided to include modified by cardanol polyamide, auxiliary agent C and mixed solvent.
Preferably, the percentage by weight of the component A is：Epoxy resin 10-18%, high-purity zinc powder 80-86%,
Environmentally friendly trbasic zinc phosphate 2-4%, auxiliary agent A/B：3-4%, mixed solvent 1-2%；Wherein component B percentage by weight is：Anacardol changes
Property polyamide 40-60%, auxiliary agent C：1-2.5%, mixed solvent 40-65%；Component A and component B mass percent is
100：10-20.
The beneficial effects of the present invention are：Such product has salt spray resistance, hyperbaric feature, and its amount of solid content reaches
95%th, metal Zn content reaches the solid proportion of 80%, paint and reaches 3.0g/ml, and salt spray resistance reaches more than 5000 hours paint films not
Foaming, rust is not returned, does not fall paint.Such product can be widely used for more severe and coastal area the metal heavy-duty product of weather
On, such as：The fields such as bridge, steel structure, ship, petroleum pipeline.
Embodiment
The present invention is described in further detail below in conjunction with specific embodiment.
Embodiment
Raw material is as follows：
Epoxy resin (E44, Yueyang Ba Ling petrochemical industry)
High-purity zinc powder (500 height of eye purity zinc powder Jiangsu section Cheng Xinye)
Environmentally friendly trbasic zinc phosphate (PZ20 ring fine jades chemical industry)
Auxiliary agent A (engraves this chemistry in 1501 seas).
Claims (2)
