Description
Technical field
The invention belongs to technical field of coatings, and in particular to a kind of thermostable heat-isolating coating.
Background technology
It is well known that in order to realize the target of ecological, environmental protective, energy-saving and emission-reduction, to gold such as industrial heat supply pipeline, heat power equipments
Effective heat-insulation and heat-preservation anti-corrosion measure must be taken by belonging to body structure surface.In the prior art, traditional heat-insulating heat-preserving material such as rock wool
Felt, inorganic heat insulation mortar, polyphenyl foam plate, polyurathamc etc. use relatively broad, but these traditional thermal insulation materials
Use have to reach certain thickness and can just have preferable heat-insulating property, more time-consuming in construction, construction quality is determined
It is poor to determine its water proofing property, there is also sunlights to be susceptible to thermal insulation dehiscence, infiltration for open air, directly affects metal watch
The antiseptic property in face.And insulating layer is done using organic polymer expanded material, flame resistance is poor, and there are certain fire is hidden
Suffer from.Therefore, recent domestic all substitutes traditional thermal insulation material in development of new thermal insulation material.Wherein, with cenosphere
Nano paint for main stuffing exploitation lightweight, thin layer, high temperature insulating becomes the research hotspot in the field.Although being proposed successively
The preparation method of some of such thermal insulation material, but be not very ripe, it is also in conceptual phase, apart from large-scale promotion application
Also a certain distance.Developing a kind of coating as early as possible has scumbling, thermal insulation, high temperature resistant, waterproof, cracking resistance, anti-corrosion, sound insulation, resistance to
Wait resistance to characteristic of waiting so long is the current vital task of the art at nanometer thermostable heat-isolating coating.
Invention content
The present invention proposes a kind of thermostable heat-isolating coating, and the thermal insulation coatings thermal insulation is good, high temperature resistant, intensity are high, resistance to
Pollution.
The technical proposal of the invention is realized in this way：
A kind of thermostable heat-isolating coating, according to the number of parts by weight, including following components：
40~60 parts of organosilicon modified polyester acrylate, 20~30 parts of acrylic emulsion, modified crystal whisker of hexa potassium titanate 4~
8 parts, 3~6 parts of alumina silicate fibre, 6~10 parts of hollow tiny pearl, 3~6 parts of dispersant, 4~8 parts of wetting agent, thickener 4~8
0.5~1.5 part of part, 20~30 parts of deionized water and pH adjusting agent；The modified crystal whisker of hexa potassium titanate is mainly by potassium hexatitanate crystalline substance
Palpus, silicon nitride and silane coupling agent are prepared.
Preferably, the preparation method of the modified crystal whisker of hexa potassium titanate：
Crystal whisker of hexa potassium titanate and silicon nitride are added in acetone, ultrasonic disperse is carried out, dispersion liquid is obtained, by dispersion liquid liter
Then temperature sequentially adds silane coupling agent, water and polyamide, stirs evenly to 75~82 DEG C, dry after reaction.
Preferably, the mass ratio of the silicon nitride and the crystal whisker of hexa potassium titanate is 1:5~7, the silane coupling agent
Mass ratio with the crystal whisker of hexa potassium titanate is 1:20~25, the mass ratio of the polyamide and the silicon nitride is 1:15
~20.
Preferably, the silane coupling agent is KH550 or KH560.
Preferably, the dispersant is in hydrophobic modified carboxylic acid sodium salt, polyacrylic acid sodium salt or ammonium polyacrylate salt
One or more.
Preferably, the wetting agent is selected from neopelex or lauryl sodium sulfate.
Preferably, the thickener is in diatomite, sodium bentonite, polyurethane, polyvinyl alcohol and polyacrylamide
One or more.
The preparation method of the thermostable heat-isolating coating of the present invention：Said components are weighed according to proportioning, are mixed equal
It is even.
Beneficial effects of the present invention：
1, the present invention selects organosilicon modified polyester acrylate and acrylic emulsion as film forming matter, in organosilicon height
In polymers, the bond energy (346kJ/mol) of the covalent bond energies (451kJ/mol) of Si-O keys than the C-C keys in common organic polymer
Greatly, and Si-O atoms form d-p pi bonds, increase the stability of high polymer.In Organosilicon Polymers hydroxyl is connected on Si atoms
After by thermal oxide, generation is hot crosslinked more stable Si-O-Si keys, can prevent the fracture of its major key from degrading.Namely
It says, when by thermal oxide, forms Si-O-Si key protection layers, alleviate the internal influence to high polymer.Organosilicon modified polyester third
Olefin(e) acid ester is a kind of polymer three-dimensional cross-linking compounds, and film is in rigidity, and thermal coefficient is smaller, and heat-resisting quantity is good, water proof anti-seepage
Excellent, the strong adhesive force of property, but Low temperature-resistanflexible flexible is poor.Self-crosslinking elastomeric propylene yogurt liquid, glass transition temperature is low, thermal coefficient is low,
The advantages that elastic-plastic is good, lower temperature resistance is excellent, water impermeability is good, adhesive force is good, but heat-resisting quantity is poor.By two kinds of lotions with
Certain proportion mixture is compound to make binder, and the protrusion that the insulating moulding coating of preparation had both maintained organosilicon modified polyester acrylate is excellent
Point also maintains the strong point of acrylic resin, can get learn from other's strong points to offset one's weaknesses, the effect of mutual supplement with each other's advantages.
2, the preparation method of modification crystal whisker of hexa potassium titanate of the invention is：Crystal whisker of hexa potassium titanate and silicon nitride are added to third
In ketone, ultrasonic disperse is carried out, dispersion liquid is obtained, dispersion liquid is warming up to 75~82 DEG C, then sequentially adds silane coupling agent, water
It with polyamide, stirs evenly, dries after reaction.The modification crystal whisker of hexa potassium titanate that this method obtains has higher steady
Qualitative and high temperature resistance, to make crystal whisker of hexa potassium titanate have high temperature sound-absorbing, chemical stability, insulating properties, reflection infrared ray,
Excellent antiseptic property etc., moreover it is possible to improve apply coating rigidity, solve individually by crystal whisker of hexa potassium titanate modification bring it is steady
The problem of qualitative difference and temperature tolerance difference.
