Abstract
The invention discloses a kind of thickener, include each component of following parts by weight：36 40 parts of PPG, 16 18 parts of toluene, 20 26 parts of diisocyanate, 14 16 parts of dibutyl tin laurate, 15 18 parts of n-hexane, 79 parts of methyl iso-butyl ketone (MIBK), 7 10 parts of NPE, 10 15 parts of polyethylene glycol, 15 18 parts of chain extender.The advantage of the technical program is：Hydrophilic radical and hydrophobic grouping are introduced in its molecular structure, when increasing concentration of aqueous solution, easily form micella and form network structure with latex particle, increase the viscosity of emulsion paint, deposited phenomenon degree in emulsion paint product is significantly reduced simultaneously, the using effect of emulsion paint is improved.
Description
Technical field
The present invention relates to a kind of coating additive, especially a kind of thickener.
Background technology
With the development of building and house ornamentation technology, the coating such as paint there has also been significant progress.The use of coating is not only
Only be to play a part of decoration, the material of matrix can also be protected from the corrosion and damage of environmental factor, extension building, equipment and
The life-span of household articles.Water paint is with water as solvent or makees the coating of decentralized medium, water paint have it is excellent not
Viscosity, durability and environmental-protecting performance, have a wide range of applications in all trades and professions.
Consumption of the coating additive in coating seldom, but can significantly improve coating property, it has also become coating is indispensable
Part.Thickener is a kind of auxiliary rheological agents, can not only thicken coating, prevents sagging phenomenon occur in construction, and
The excellent mechanical performance of coating and bin stability can be assigned.It is very important for the relatively low water paint of viscosity
One analog assistant.But traditional water paint thickener is when in use, especially during the painting of emulsion paint, though latex can be made
System viscosity increase is painted, but there can be deposited phenomenon, the using effect of emulsion paint is reduced.
The content of the invention
Increase the thickener of viscosity it is an object of the invention to provide a kind of, solve one in above-mentioned prior art problem or
Person is multiple.
In order to solve the above technical problems, the technical scheme is that：A kind of thickener, including following parts by weight are each
Component：36-40 parts of PPG, 16-18 parts of toluene, 20-26 parts of diisocyanate, dibutyl tin laurate 14-16
Part, 15-18 parts of n-hexane, 7-9 parts of methyl iso-butyl ketone (MIBK), 7-10 parts of NPE, 10-15 parts of polyethylene glycol expands
15-18 parts of chain agent.
In some embodiments, chain extender is included one in tirethylene glycol, ethoxyquin pentaerythrite or triethanolamine
Plant or a variety of mixing.
In some embodiments, chain extender includes tirethylene glycol, ethoxyquin pentaerythrite and triethanolamine, two contracting second
The parts by weight ratio of glycol, ethoxyquin pentaerythrite and triethanolamine is 1：2：1.
In some embodiments, Emulsion paint thickener is colourless-slightly yellow clear viscous liquid.
In some embodiments, viscosity is 3500~4000mPa ﹒ s to Emulsion paint thickener at normal temperatures.
In some embodiments, the pH value of Emulsion paint thickener is 7~8.
The advantage of the technical program is：Hydrophilic radical and hydrophobic grouping are introduced in its molecular structure, in increase water
During solution concentration, easily form micella and form network structure with latex particle, increase the viscosity of emulsion paint, significantly decrease simultaneously
Deposited phenomenon degree in emulsion paint product, improves the using effect of emulsion paint.
Embodiment
A kind of thickener, its innovative point is：Include each component of following parts by weight：36-40 parts of PPG,

7-9 parts of base ketone, 7-10 parts of NPE, 10-15 parts of polyethylene glycol, 15-18 parts of chain extender.
In some embodiments, chain extender is included one in tirethylene glycol, ethoxyquin pentaerythrite or triethanolamine
Plant or a variety of mixing.
In some embodiments, chain extender includes tirethylene glycol, ethoxyquin pentaerythrite and triethanolamine, two contracting second
The parts by weight ratio of glycol, ethoxyquin pentaerythrite and triethanolamine is 1：2：1.
In some embodiments, Emulsion paint thickener is colourless-slightly yellow clear viscous liquid.
In some embodiments, viscosity is 3500~4000mPa ﹒ s to Emulsion paint thickener at normal temperatures.
In some embodiments, the pH value of Emulsion paint thickener is 7~8.
The advantage of the technical program is：Hydrophilic radical and hydrophobic grouping are introduced in its molecular structure, in increase water
During solution concentration, easily form micella and form network structure with latex particle, increase the viscosity of emulsion paint, significantly decrease simultaneously
Deposited phenomenon degree in emulsion paint product, improves the using effect of emulsion paint.
The scope of the present invention is defined by the appended claims and its equivalents.Described above is only the present invention
Preferred embodiment, it is noted that to those skilled in the art, do not departing from the invention design premise
Under, some similar modification and improvement can also be made, these also should be regarded as within protection scope of the present invention.
