The present invention relates to functional paint technology, it is desirable to provide a kind of Nano-meter SiO_2 for being used to coat valve2The preparation method of modified inorganic coating.This method includes：Silane coupler KH570, butyl titanate, water, organic acid, ethanol are well mixed, it is stand-by after reacting 10 hours；Silicon dioxide gel, α nano aluminium oxides, γ nano aluminium oxides and iron oxide black pigment are added into ball mill, ball milling 1h；After the reaction product of two steps and mixture blending, continue stirring 1 hour, that is, obtain coating products.Paint adhesion of the invention is strong, corrosion-resistant, ageing-resistant performance is good, while has higher hardness.It can be formed and be chemically bonded with valve substrate, thus there is good adhesive force, meanwhile, coating system is inorganic system, and mechanical strength is much larger than the coating of existing coating preparation after nano combined, so as to effectively extend the service life of metal valve.
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 preparation method of the inorganic coating of property.
Background technology
Valve is the control unit in fluid delivery system, has cut-off, regulation, water conservancy diversion, prevents adverse current, voltage stabilizing, shunting
Or the function 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 that the coating for being sprayed on metal valve internal structure needs to have stronger anti-corrosion and ageing resistace and anti-wear performance.
The content of the invention
The technical problem to be solved in the present invention is to overcome deficiency of the prior art, there is provided a kind of to be used to coat valve
Nano-meter SiO_22The preparation method of modified inorganic coating.The paint adhesion is strong, corrosion-resistant, ageing-resistant performance is good, simultaneously
With higher hardness.
To achieve these goals, the technical solution adopted in the present invention is：
A kind of preparation method of the inorganic coating for the nanosized SiO_2 modification for being used to coat valve, including following steps are provided
Suddenly：
(1) ratio weighs each raw material by weight：Silane coupler KH570 10-15 parts, butyl titanate 10-15 parts, water
3-5 parts, silicon dioxide gel 20-40 parts, 10 parts of α nano aluminium oxides, 5 parts of γ nano aluminium oxides, iron oxide black pigment 15-20 parts, have
Machine acid 3-5 parts, hydroxy silicon oil 5-10 parts, 20 parts of ethanol；
(2) silane coupler KH570, butyl titanate, water, organic acid, ethanol are well mixed, reaction is treated after 10 hours
With；
(3) silicon dioxide gel, α nano aluminium oxides, γ nano aluminium oxides and iron oxide black pigment are added into ball mill, ball milling
1h；
(4) by after the blending of the mixture of the reaction product of step (1) and step (2), continue stirring 1 hour, that is, applied
Expect product.

The application method of the coating comprises the 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) surface drying is heat-treated 30 minutes after 2 hours 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 coupler, it is by hydrolyzing to form
Active silicone hydroxyl, polymerisation can occur with the hydroxyl of metal surface and form firm chemical bonding, therefore the adhesive force of coating is significantly
Improve.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：
