Abstract
A kind of Zinc powder-free water-based primer of the present invention, raw material and raw material weight percentage composition are as follows：Lithium metasilicate 40 50%, ferrophosphorus powder 0.1 1%, zinc-iron powder 0.1 3%, polyvinyl alcohol 0.1 3%, titanium nitride 0.1 3%, chloroform 40 60%.The present invention solves the problems, such as the secondary rust removal brought because of zinc powder, solves the health hazard to construction personnel and the pollution to environment, meanwhile, in the case where ideal conditions is can't bear in surface treatment, adhesive force is substantially better than inorganic zinc class product.
Description
Technical field
The present invention relates to a kind of aqueous priming paint more particularly to a kind of Zinc powder-free water-based primers, belong to technical field of coatings.
Background technology
Currently as the anti-corrosion and shop primer of iron structure, zinc rich primer is the most universal, important.Zinc-rich paint is mainly
The anti-corrosion of various iron structures is used in the form of zinc rich primer, because being rich in a large amount of electrochemistry rust resisting pigment-zinc in its formula
Powder, therefore it is referred to as zinc-rich paint.
Zinc-rich paint paint film is hard, adhesive force is good, antirust ability is strong, has excellent three proofings (moisture-proof, salt spray proof, mould proof)
Performance and oxidation-resistant corrosion-resistant performance；Excellent cathodic protection effect and static conductive effect, have no adverse effects to welding performance, can
It is used with most of coatings system, has become most universal, most important priming paint in the ferrous metal corrosion protections application field such as steel.
Zinc rich primer can be divided into two major classes in production and application aspect, i.e., using inorganic matters such as silicates as the inorganic of adhesive
Zinc rich primer and using epoxy resin as the organic zinc-rich primer of adhesive.When for corrosion-resistant field, they all must satisfy with
Lower requirement：1. must carry out blasting treatment by painting ground just can guarantee its construction quality：Since the zinc powder in priming paint wants same steel
Its electro-chemical protection of close contact competence exertion, therefore the pre-treatment of matrix surface is required stringent；2. it is appropriate to need to be equipped with
Intermediate coat and finishing coat：Zinc rich primer paint film is usually relatively thin, and is easily influenced by external environment medium, therefore does not make individually generally
With need to be equipped with intermediate coat and finishing coat appropriate, reach defined film thickness.
Priming paint is the first layer of paint system, for improving the adhesive force of finishing coat, the richness for increasing finishing coat, providing alkali resistant
Property, anti-corrosion function etc. is provided, while can ensure the uniform pickup of finishing coat, paint system is made to play optimum efficiency.
Aqueous priming paint is the abbreviation of Water-soluble environment-friendlyanticorrosive metal protection priming paint, is with groups such as water-base resin, lead-free pigment, water
At having the characteristics that fast drying, barrier propterty are excellent etc., can be used for the protective underlayer coating of metal substrate.Aqueous priming paint coating can
It is constructed using the methods of dip-coating, showering, spraying, the painting of metal substrate suitable for industrial equipment, the vehicles and the product for civilian use
Decorations, the protection especially suitable for exporting steel surface are covered with paint, lacquer, colour wash, etc..
Since the content of zinc powder in zinc-rich paint (paint) is between 85-95%, secondary flash rusting is easy tod produce；It derusts to ground
It is required that high；Since zinc powder is a kind of mineral metal products of costliness, price skyrockets from 10 yuan/kg to 30 yuan/kg or more；Construction party is come
It says：To substrate surface treatment must sandblasting ball blast reach Sa2.5 grades of mechanical derusting or more；Roughness within 50~100 μm, and
Cover connection paint is applied in the most short time, otherwise will produce secondary flash rusting, it is high for derusting requirement, to the requirement of personnel's labor protection
Sternly；And it is expensive.
Although inorganic zinc rich paint has the advantages that fast drying, heat safe, the paint film of zinc rich paint is in electric welding cutting flame
It when operation, has a large amount of zinc and overflows, the steam of generation brings serious harm to the health of operating personnel, and operating personnel hold
Easily cause hot zinc disease.
Therefore, this field has a kind of easy for construction, three proofings of exploitation (moisture-proof, salt spray proof, mould proof) to have excellent performance, corrosion-resistant,
The needs of the good Zinc powder-free water-based primer of salt spray resistance.The preparation of the Zinc powder-free water-based primer and work progress, especially
It is that should avoid overflowing zinc in electric welding cutting flame operating process, causes hot zinc disease.
Invention content
To solve above-mentioned existing technical problem, the present invention uses following scheme：
A kind of Zinc powder-free water-based primer, raw material and raw material weight percentage composition are as follows：
Lithium metasilicate 40-50%；
Ferrophosphorus powder 0.1-1%；
Zinc-iron powder 0.1-3%；
Polyvinyl alcohol 0.1-3%；
Titanium nitride 0.1-3%；
Chloroform 40-60%.
The present invention solves the problems, such as to solve health hazard to construction personnel and right because of the secondary rust removal that brings of zinc powder
The pollution of environment, meanwhile, in the case where ideal conditions is can't bear in surface treatment, adhesive force is substantially better than inorganic zinc class product.
Specific implementation mode
Below in conjunction with specific embodiment, the present invention will be described in detail, herein illustrative examples and explanation of the invention
For explaining the present invention, but it is not as a limitation of the invention.
Embodiment
A kind of Zinc powder-free water-based primer of the present invention, raw material and raw material weight percentage composition are as follows：Lithium metasilicate 45%,
Ferrophosphorus powder 0.5%, zinc-iron powder 0.5%, polyvinyl alcohol 1%, titanium nitride 2%, chloroform 51%.
The above-described embodiments merely illustrate the principles and effects of the present invention, and is not intended to limit the present invention.It is any ripe
The personage for knowing this technology can all carry out modifications and changes to above-described embodiment without violating the spirit and scope of the present invention.Cause
This, institute is complete without departing from the spirit and technical ideas disclosed in the present invention by those of ordinary skill in the art such as
At all equivalent modifications or change, should by the present invention claim be covered.
