[technical field]
It is especially a kind of for the water-thinned epoxy zinc-rich shop primer of container and its preparation the present invention relates to a kind of coating
Technique.
[background technique]
Traditional coating container is mostly solvent based coating, and common kind has epoxy, chlorinated rubber, acrylic acid, poly- ammonia
Ester etc., wherein containing a large amount of organic solvent, these solvents are harmful to construction personnel's health and pollute environment.Foreign countries were from 70 years
In generation, has just just carried out the environmentally friendly antiseptic and rustproof paint such as high solid, solvent-free, powder and water paint and has developed, wherein aqueous
For paint because cost is relatively low, construction safety is convenient, and film thickness is easy to control, and obtains more research.But because technical difficulty is larger, long-term is not
Obtain big progress.Since the mid-80, countries in the world legislations of environmental protection contains volatile organic solvent in coating (VOC)
The limitation of amount is increasingly strict, the upsurge for causing water-based anticorrosive paint to be studied.
Domestic and international existing aqueous heavy-d uty system priming paint has aqueous inorganic zinc-rich, water-based epoxy zinc-rich primer.Aqueous nothing
The antiseptic property of machine zinc rich primer is excellent, but harsher to ground processing, construction environment, the requirement of mating coating, such as ground
It is required that passing through blasting treatment or 2.5 grades of hand cleaning；Ambient humidity requires to be greater than 50%；Mating coating needs can be resistant to inorganic silicon
The strong basicity of hydrochlorate, it is desirable that have bottom closing paint in order to avoid there are a large amount of bubbles；Therefore certain use occasions limit its application.Such as
Container shop primer requires construction rhythm fast, and baking time is short, general only to be stacked within 90 seconds or so, existing water
Property epoxy zinc rich primer is unable to reach this requirement.
[summary of the invention]
It is an object of the invention in view of the above deficiencies, provide, a kind of antiseptic property is good, rate of drying is fast, surface initial stage is hard
Degree establishes fast water-based epoxy zinc-rich primer.
The technical solution of the present invention is as follows: a kind of water-based epoxy zinc-rich primer, including component A and B component,
Wherein component A includes:
Wherein B component includes:
65~75wt% of aqueous epoxy resins,
25~35wt% of softened water；
Component A and B component mass ratio are 100:28.
Preferably, the aqueous epoxy curing agent is that solid part changes for the fatty amine modification of 70~80wt% or polyamide
The aqueous epoxy curing agent of property.
Preferably, the zinc powder is the zinc powder that dry film content is 80wt%, wherein water-soluble substances content < 0.5wt%.
Preferably, the cosolvent can be one or more of propylene glycol monomethyl ether, butyl glycol ether, isopropanol
Mixture: its content is 8~15wt%.
Preferably, the anti-settling agent is one or more of fumed silica, cellaburate, modified urea solution
Mixture.
Preferably, the aqueous epoxy resins are the aqueous epoxy emulsions that solid part is 50-60wt%；
Preferably, the neutralizer is volatile organic amines.
Water-based epoxy zinc-rich primer scene mixing of the invention will not generate dust, and environmental protection is harmless；Scene mixing
It is easy, it is only necessary to which simple agitation can be uniformly mixed；It is safe and convenient to use, no pollution to the environment, to construction personnel's health
It is harmless；It can be constructed by the way of airless spraying, compressed air spraying, roller coating, easy for construction, raising construction effect
Rate；Air drying speed only needs that next process can be carried out within tens seconds fastly e.g. to stack, punching press etc., paint film mechanical strength
Height, early stage wearability are good, and adhesive force is strong, and antiseptic property is excellent, is applicable to the occasions such as ship, bridge steel structure, container
Anti-corrosion and protection can also be used as shop primer use.
[specific embodiment]
Technical solution of the present invention is further elaborated now in conjunction with embodiment, it is believed that be for a person skilled in the art
Clearly.
If table 1 is the embodiment of the present invention, wherein each component content is mass percentage, but the invention is not limited to
Following instance.
Table 1
In table 1, aqueous epoxy curing agent can equally replace with the fatty amine that other solid parts are 70~80wt% and change
The aqueous epoxy curing agent of property；Propylene glycol monomethyl ether can equally replace with acetone；The graceful epoxy emulsion 3961-1 of Hensel can be waited
Replace with to amount the water-base epoxy dispersion or aqueous epoxy emulsion that other solid parts are 50~55wt%.
