Description
Technical field
The present invention relates to technical field of anticorrosion more particularly to a kind of New type water pipe elbow anticorrosive coatings.
Background technology
Water pipe elbow achievees the purpose that flow turning conveying for connecting two straight drainpipes.Since sewerage is made a living
Waste water living or production waste water, have certain corrosivity in chemical property, and elbow usually will produce turbulent flow, elbow be pressurized compared with
Greatly, flow is often dredged or buffered in structure, causes sewerage and elbow contact area larger, the time is longer, perishable to ooze
Leakage, elbow are replaced frequently, not only cause the waste of manpower and materials, returning resident living makes troubles.
The antiseptic property of water pipe elbow is the greatest problem for improving its durability, has many patents to propose one in the prior art
A little erosion shields, however because the working environment of water pipe elbow limit, for a long time with there is sour or alkaline waste water, it is existing
Technology in corrosion-inhibiting coating cannot be satisfied long-term anti-corrosion demand.
Invention content
The purpose of the present invention is for the defects in the prior art, proposing a kind of New type water pipe elbow anticorrosive coating,
It using anticorrosive coating produced by the present invention, can effectively ensure that water pipe elbow is not perishable for a long time, improve its service life, reduce
Cost.
The present invention is achieved by the following technical solutions：
A kind of New type water pipe elbow anticorrosive coating, wherein its constituent is as follows according to the mass fraction：
25-35 parts of isocyanates
10-25 parts of amino resins
4-9 parts of biuret
5-10 parts of Si oxide of nanometer
3-9 parts of graphite powder
4-8 parts of zinc oxide
Recessed 3-8 parts of soil
6-12 parts of dispersant.
Above-mentioned a kind of New type water pipe elbow anticorrosive coating, wherein preferably, constituent is according to the mass fraction such as
Under：
32 parts of isocyanates
19 parts of amino resins
8 parts of biuret
10 parts of Si oxide of nanometer
5 parts of graphite powder
7 parts of zinc oxide
Recessed native 6 parts
11 parts of dispersant.
Above-mentioned a kind of New type water pipe elbow anticorrosive coating, wherein the dispersant is atoleine or calcium stearate
In one kind.
Beneficial effects of the present invention are：
The present invention uses new formulation, and a part is Organic Ingredients, including amino resins, amino resins and biuret,
It is class polyurea structure that the polymer formed is closed in polymerization, and rapid curing can be realized by being not only not necessarily to curing agent, adapt to arbitrary surface, inclined-plane
With the coated and molded of vertical plane, and with prominent acidproof, alkaline resistance properties；Another part is inorganic raw material, including nanometer silica
Compound, graphite powder and zinc oxide not only make coating coating and have some strength and rigidity after elbow, and reason water impact is not made
It collapses at coating, and makes that coating is acidproof or caustic corrosion is stronger；It is set with the formula that inorganic raw material is combined using Organic Ingredients
Meter make coating from it is organic different with inorganic substances binding ability, it is not perishable to ooze through the sewage long period of soaking that chemical property is unknown
Leakage.
The present invention additionally uses recessed soil, it is the magnesium alumino metasilicate containing Shuifu County of a kind of layer of chain structure, salt clay mineral, not only
With surface active function, make coating surface that there is aqueous lubricating, flow is by easily lubrication water conservancy diversion, moreover it is possible to make coating at low temperature
It is functional, it ensure that the underground job of elbow when temperature is relatively low；Make organic to mitigate disappearing of being with inorganic raw material using dispersant
Bubble, dispersion and degranulation, ensure that the close property processed and uniformity of coating.
The novel formula of the present invention is reasonable, is coated on elbow internal diameter, ensures that water pipe elbow is not easy corrosion leakage for a long time, and
And with certain water-fast impact, the service life of water pipe elbow is substantially increased, cost is reduced.
