Description
Technical field
The present invention relates to the production technical fields of aqueous reversible high temperature caution paint.
Background technique
High temperature caution paint is mainly used for the facility that some mechanical equipments, boiler etc. have temperature, has certain dicoration,
Meanwhile, it is capable to which the color of paint film is changed into yellow by green when substrate reaches certain temperature, can still restore after temperature reduction
The original color of film, to achieve the purpose that warn at a certain temperature.
Common high temperature caution paint is all solvent based product, and wherein VOC content is high, is easy to cause damages to environment, no
Conducive to energy-saving and emission-reduction.And some cities in current China have been promulgated and have been ordered within a certain time VOC, therefore solvent type high temperature caution paint
Using also more and more receiving limitation.
Water paint is all smaller to the harm of environment and construction personnel due to containing extremely low VOC, also therefore receives
Country widelys popularize.Water soluble acrylic acid organic silicon resin paint has certain heat resistance, be also very suitable for preparing it is aqueous can
Inverse type high temperature caution paint.
Summary of the invention
For the deficiency of solvent type high temperature caution paint, it is an object of that present invention to provide a kind of good environmental protections, weatherability
The preparation method of the aqueous reversible high temperature caution paint of good normal temperature cure.
The present invention includes the following steps：
1）Water soluble acrylic acid organic siliconresin is mixed with neutralizer, deionized water, it is agitated, obtain that pH value is 8~9.5
One mixed system；
2）Deionized water, cosolvent, dispersing agent, levelling agent, defoaming agent and the first mixed system are mixed, filler is then added
It is ground, obtains second mixed system of the fineness less than 30 μm；
3）After dispersing temperature-indicating pigment in the second mixed system mixed system, thickener, deionized water are added, is obtained aqueous
Reversible high temperature caution paint.
The present invention, as main coloured material, cooperates water soluble acrylic acid organic siliconresin good resistance to using temperature-indicating pigment
Time property and high temperature resistance, using deionized water as solvent, obtained aqueous reversible high temperature caution paint, the product prepares work
Skill is simple.Product is water-thinned Normal temperature coating, and VOC content < 80g/L belongs to environmentally friendly product.When the product shines
Between it is long, weatherability is good, is not pulverized easily, the up time is long.
Further, water soluble acrylic acid organic siliconresin of the present invention accounts for aqueous reversible high temperature caution paint total amount
5~20wt%, the filler that 30~45wt%, temperature-indicating pigment account for aqueous reversible high temperature caution paint total amount account for aqueous reversible high temperature
10~15 wt % of caution paint total amount.
As a kind of aqueous finish paint for having specific function, the dicoration of film also be there are certain requirements, aqueous in the present invention
Acrylic acid organic siliconresin dosage is 30~45wt%, on the one hand can reach the decorative effect of semi-gloss, while can also effectively be promoted
Product weatherability and anticorrosive property.
Temperature-indicating pigment dosage be 5~20wt%, dosage be lower than 5%, then temperature indicating effect is unobvious, and temperature indicating temperature difference compared with
Greatly.Dosage is more than 20%, then temperature indicating effect is prominent, and temperature indicating temperature is more accurate, but coating products increased costs are more, sexual valence
Than decline.
The neutralizer accounts for 1~2wt% of aqueous reversible high temperature caution paint total amount, and deionized water accounts for aqueous reversible
10~30wt%, the cosolvent of high temperature caution paint total amount account for 1~5wt% of aqueous reversible high temperature caution paint total amount.
For water paint, the pH value of system is very crucial to the stability of system.Generally, water paint exists
It plays pendulum under acidic environment, the stable balance of water oil phase can be then reached under alkaline environment.And coating uses
Pigments and fillers be typically all through peracid treatment, faintly acid is shown in water-based system, this will use amine neutralizer to system
It is neutralized, with the stability of guarantee system.
Neutralizer of the present invention be in multifunctional assistant AMP-95 or ammonium hydroxide or diethanol amine at least any one, it is more
Kind amine neutralizer compounding can more guarantee there is good stability in each season.
The dispersing agent be BYK-190 or Disuper S30 at least any one.BYK-190 and Disuper S30
It is high molecular weight polymers, BYK-190 can be acted on by space stability ultimate load makes pigment solution flocculate.It is flocculated due to solving
Pigment particle size is small, therefore can obtain high glaze, and promotes color intensity.Disuper S30 belongs to more macromolecule
Hyper-dispersant, can more efficiently reduction system viscosity, to obtain bigger formula adjustment space.
The levelling agent is HyperLev F40；Defoaming agent be TEGO 901W or 902W at least any one；Thickening
Agent be Borchi 0620 or Borchi 0434 at least any one；Cosolvent is isopropanol, ethylene glycol, N- methylpyrrole
In alkanone at least any one.
HyperLev F40 is a kind of special organosilicon polymer.It is compounded with levelling, wetting and defoaming function and passes through reduction
Coating surface tension is to improve the wetability of ground.
TEGO 901W or 902W are then the polyether silicone co-polymers containing fumed silica, belong to strength organosilicon
Deaeration defoaming agent can effectively eliminate the micro-bubble in water paint.
The temperature-indicating pigment is organically-modified temperature-indicating pigment.When the pigment is heated to certain temperature, certain occurs for pigment structure
A little physical changes or chemical change lead to molecular structure, molecular conformation variation, cause color change to indicate temperature.The present invention
The organically-modified temperature-indicating pigment used, under certain temperature action, molecular structure is subjected to displacement without generator terminal lattice, i.e.,
Another crystal form is become from a kind of crystal form and leads to color change, lattice restores to the original state after being cooled to certain temperature, color
It restores therewith.Using the temperature-indicating pigment of organically-modified mistake, stability is more preferable, and validity period is longer.
Green can be presented in the temperature-indicating pigment that the present invention uses under 80 DEG C of cryogenic conditions, and temperature reaches 80 DEG C or more and is in
Existing yellow, temperature indicating effect is good, and 5 DEG C of temperature difference <.Make coating weather resistance is good, is exposed to open air to be for a long time not pulverized easily.
The step 2）When the middle mixing by deionized water, dispersing agent, levelling agent, defoaming agent and the first mixed system, use
The mixing speed of 800~1000rpm of revolving speed, too fast mixing speed easily cause mill base to splash.
