Curing agent component:Comprise the material that following weight is divided, 650 polyamide 40-65 parts, dimethylbenzene 20-40 part, butanol 15-20 part.
The further technical scheme of the present invention is, also comprises acid organic siliconresin in described paint component, its weight portion For 15-70 part.
Scheme two:
Special high-temperature is from the preparation method of dry insulation enamel paint it is characterised in that using filling a prescription as above, preparation method is such as Under, add acid organic siliconresin, titanium dioxide, iron oxide red, white glaze according to this toward inside tank of sizing mixing, then start mixer slow Stirring, properly increases mixing speed after stirring, material is tuned into mill base, enters horizontal skin grinder and is ground, and reaches thin Degree below 30um;
Mill base through grinding enters sizes mixing in tank, starts stirring and adds remaining epoxy resin, KH-550 coupling agent, uses diformazan Benzene:Butanol compares 6 according to weight:The viscosity of paint is adjusted to 25-35 second/painting -4, more than 23 degrees Celsius, filter and package by 4.
Using the present invention of as above technical scheme, have the advantages that with respect to prior art:This product is at 400 DEG C Not flashover under high temperature, does not pull out electricity, do not puncture it is ensured that main equipment surface there is good insulating properties it is ensured that equipment run can Personal safety by property and personnel.
Specific embodiment
Below embodiments of the invention are illustrated, embodiment is not construed as limiting the invention:
Comprise paint component:It comprises the material of following weight portion, titanium dioxide 10-25 part, iron oxide red 3-8 part, white glaze 8-15 Part, epoxy resin 3-7 part, KH-550 auxiliary agent 0.5-5 part;The KH-550 comprising 20-45 part in KH-550 auxiliary agent therein is coupled Agent and the dimethylbenzene of 55-80 part;Also comprise curing agent component:It comprises the material of following weight fraction, 650 polyamides 40-65 part, dimethylbenzene 20-40 part, butanol 15-20 part.Acid organic siliconresin is also comprised, its weight portion in described paint component For 15-70 part.Special high-temperature is filled a prescription from the preparation method of dry insulation enamel paint as above it is characterised in that adopting, preparation side Method is as follows, adds acid organic siliconresin, titanium dioxide, iron oxide red, white glaze according to this, then start mixer toward inside tank of sizing mixing It is slowly stirred, after stirring, properly increases mixing speed, material is tuned into mill base, enter skin grinder and be ground, reach thin Degree below 30um;Mill base through grinding enters in paint mixing tank, starts stirring and adds remaining epoxy resin, KH-550 to be coupled Agent, uses dimethylbenzene:Butanol compares 6 according to weight:The viscosity of paint is adjusted to 25-35 second/painting -4 by 4, more than 23 degrees Celsius, bag filter Dress.
Special high-temperature should meet following index from dry insulation enamel paint:
Under atmospheric environment, cannot realize carrying out crosslinking under normal temperature condition from one pack system, generate network structure it is necessary to introduce Another component, the chemical group of bi-component reacts to each other under atmospheric environment, generates network structure.
1053 organic siliconresins are the best thermosetting resins of heat resistance in insulating materials, because it is hot setting tree Fat, is not suitable for doing the paint of normal temperature cure.
From modified organic siliconresin, group can be solidified at normal temperatures using curing agent, makes self-drying paint, this patent From polyamide as curing agent, amide group and epoxy reaction are crosslinked, and modified organic silicone resin heat resistance is than organic Silicones is lower slightly, but still belongs to H level heat proof material, and modified organic siliconresin increased adhesive force, improves intensity.
Auxiliary material includes coloring pigment and extender pigment and auxiliary agent composition, and the principle of selection must have heat resistance, this product Product can be made into pink, white paint, because selecting coloring pigment titanium dioxide, its heat resistance and insulating properties all relatively good, titanium White powder is divided into rutile and two kinds of anatase titanium dioxide again, and the chemical stability of rutile, heat resistance are all good than sharp titanium, the fusing point of rutile Up to 1850 degrees Celsius, dielectric constant 114, and sharp titanium, at 1200-1300 degree Celsius, converts to rutile, the dielectric of anatase titanium dioxide Constant is 48, lower than rutile.
Iron oxide red is inert pigment, and optical characteristics and chemical characteristic are stable, and tinting strength, tinting power is only second to carbon black, heat-resist, Up to 1200 degrees Celsius, ferrite red impurity is few, and purity is high, so using ferrite red as coloring pigment.Carbon black impact is absolutely Edge, therefore reduces as far as possible and uses.
In order to increase the viscosity of paint, increase the electrical strength of paint film, prevent paint precipitation, increase the mechanicalness of paint Can, select multiplex extender pigment such as silica flour, powdered whiting, wollastonite in powder etc., all undesirable, introduced electromagnetism material later White glaze(1130-1200 degree Celsius of fusing point), heat-resist, there is good insulating properties, sponginess again, be difficult to precipitate, in formula In also comprise coupling agent KH-550, to increase the adhesive force of paint film.
This product not flashover under 400 degrees Celsius of high temperature, does not pull out electricity, do not puncture it is ensured that main equipment surface have good Good insulating properties is it is ensured that the safety of equipment and personnel.
In a creative way, each effect above is individually present moreover it is possible to complete the combination of the above results with a nested structure.
It should be noted that multiple schemes that this patent provides comprise the basic scheme of itself, separate, not mutually Restriction, but it can also be mutually combined in the case of not conflicting, and reach multiple effects and jointly realize.
General principle, principal character and the advantages of the present invention of the present invention have been shown and described above.The technology of this area Personnel, it should be recognized that the present invention is not restricted to the described embodiments, simply illustrate this described in above-described embodiment and specification Bright principle, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, these changes Both fall within claimed scope with improving.
