Description
Technical field
The present invention relates to functional paint technical field, in particular to a kind of Nano-meter SiO_2 for being used to coat valve2Change
The inorganic coating of property.
Background technology
Valve is the control unit in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents adverse current, voltage stabilizing, shunting
Or the functions such as overflow pressure relief.Therefore, the coating for being sprayed on valve surface must have the property such as water-fast, impact resistance, heat-resisting, heat-insulated
Can, on the other hand, valve material frequently rubs in use, therefore higher for the hardness requirement of valve, especially
It is to be sprayed on the coating of metal valve internal structure to need to have stronger anti-corrosion and anti-aging property and wear-resisting property.
The content of the invention
The technical problem to be solved by the present invention is to overcome deficiency of the prior art, provide a kind of for coating valve
Nano-meter SiO_22Modified inorganic coating.The paint adhesion is strong, corrosion-resistant, ageing-resistant performance is good, while has higher
Hardness.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of Nano-meter SiO_2 for being used to coat valve is provided2Modified inorganic coating and preparation method, the coating be by
The raw material composition of following parts by weight:10-15 parts of silane coupling agent KH570,10-15 parts of butyl titanate, 3-5 parts of water, titanium dioxide
20-40 parts of Ludox, 10 parts of α nano aluminium oxides, 5 parts of γ nano aluminium oxides, 15-20 parts of iron oxide black pigment, 3-5 parts of organic acid, hydroxyl
5-10 parts of base silicone oil, 20 parts of ethyl alcohol.
In the present invention, the silicon dioxide gel be solid content be 50% water silica sol, grain graininess 30-
80nm。
In the present invention, the grain graininess of the α nano aluminium oxides is 30-50nm.
In the present invention, the grain graininess of the γ nano aluminium oxides is 50-80nm.
In the present invention, the organic acid is formic acid, acetic acid or benzene sulfonic acid.
The preparation method of the coating comprises the following steps:
(1) each raw material is weighed by the weight ratio;
(2) silane coupling agent KH570, butyl titanate, water, organic acid, ethyl alcohol are uniformly mixed, reaction 10 it is small when after treat
With;
(3) silicon dioxide gel, α nano aluminium oxides, γ nano aluminium oxides and iron oxide black pigment are added in into ball mill, ball milling
1h;
(4) will after the mixture blending of the reaction product of step (1) and step (2), continue stirring 1 it is small when to get to painting
Expect product.
The application method of the coating comprises the following steps:
(1) first by the surfaces externally and internally of valve with 200 mesh diamond dust blasting treatments, 50 micron thickness are then sprayed above
Coating;(2) after when surface drying 2 is small, it is heat-treated 30 minutes at 200 DEG C.
The realization principle of the present invention:
It is of the invention compared with general organic coating, because film forming matter employs silane coupling agent, by hydrolyzing to form
Active silicone hydroxyl can occur polymerisation with the hydroxyl of metal surface and form secured chemical bonding, therefore the adhesive force of coating is significantly
It improves.On the other hand, this coating system is inorganic system, so the hardness and ageing-resistant performance of coating are excellent.
Compared with the prior art, beneficial effects of the present invention are as follows:
1st, the paint adhesion is strong, corrosion-resistant, ageing-resistant performance is good, while has higher hardness.
2nd, the coating in the present invention can be formed with valve substrate and is chemically bonded, thus with good adhesive force, meanwhile, it applies
Material system is inorganic system, and mechanical strength is much larger than the coating of existing coating preparation after nano combined, so as to effectively prolong
The service life of long metal valve.
