A kind of ultraviolet-curing paint adding nano bamboo carbon powder and preparation method thereof
Technical field
The present invention relates to a kind of coating and preparation method thereof, particularly a kind of ultraviolet-curing paint adding nano bamboo carbon powder and preparation method thereof.
Background technology
UV is coating material solidified has become comparatively proven technique, and particularly along with the raising of people's environmental consciousness, production and researchist note the development and application that UV is coating material solidified more.UV is coating material solidified is a kind of environmental type coating, principle that it meets completely " 4E ", it is 1/5 of thermofixation that general UV solidifies energy consumption, and UV is coating material solidified less containing volatiles, pollute little, attract most researchist and developer to be that UV is coating material solidified can reduce raw materials consumption, be conducive to reducing Financial cost.
Current UV solidify material is various, but still in various degree there are some problems, coating material solidified, the generation string stress large through photocuring post-shrinkage ratio of existing UV, cause that film is crisp, sticking power and impact resistance is poor and the snappiness of film difference and the shortcoming such as hardness is low, not corrosion-resistant, easy xanthochromia is aging, this series of problems all needs to continue improvement for different purposes, reduce production cost, expand purposes.
Summary of the invention
The object of this invention is to provide a kind of ultraviolet-curing paint adding nano bamboo carbon powder and preparation method thereof.
In order to realize object of the present invention, the present invention is by following scheme implementation:
Add a ultraviolet-curing paint for nano bamboo carbon powder, be made up of the raw material of following weight part: polyester acrylate 50-55, tri (propylene glycol) diacrylate 10-12, Viscoat 295 5-8, benzoin dimethylether 4-5, dihydroxy methylpropane diacrylate 10-12, lauryl diglycidyl ether 3-5, hexabromocyclododecane 3-6, cerium oxide 1-2, linking agent TAC2-3, zirconium English powder 3-5, celestite powder 5-7, nano bamboo carbon powder 3-5, auxiliary agent 4-5;
Described auxiliary agent is made up of the raw material of following weight part: diatomite 10-13, hectorite 5-7, titanium dioxide 5-7, epoxy castor oil 3-4, lemon quintessence oil 0.1-0.2, Viscoat 295 4-6, neopentylglycol diacrylate 3-5, altax 2-3, N-BUTYL ACETATE 20-23; Diatomite is put into calcining furnace to calcine 3-4 hour at 520-540 DEG C by preparation method, takes out, is ground into 50-100 object mixed powder together with hectorite, titanium dioxide; All the other remaining components mixed, be heated to 50-60 DEG C, stir and add mixed powder after 30-45 minute, insulation grinding 1-1.5 hour, to obtain final product.
A kind of ultraviolet-curing paint adding nano bamboo carbon powder of the present invention, be made up of following concrete steps:
(1) polyester acrylate, tri (propylene glycol) diacrylate, Viscoat 295 are put into reactor and stirred, be heated to 75-85 DEG C, stir 15-20 minute;
(2) add all the other remaining components except benzoin dimethylether, continue stirring reaction 30-40 minute, make it to be uniformly dispersed;
(3) be finally cooled to 45-55 DEG C, add benzoin dimethylether, stirring reaction 20-25 minute, after cooling, grinding obtains 20-40 μm of slurry, to obtain final product.
The invention has the beneficial effects as follows: the present invention adds nano bamboo carbon powder, good dispersity, add mobility, and nano bamboo carbon powder has good electromagnetic shielding action, and energy anion releasing and far infrared rays, harmless to human-body safety; Add auxiliary agent, good leveling property, film adhesive is good, and hardness is large, wear-resisting, energy-conserving and environment-protective.
Specific embodiments
Below by specific examples, the present invention is described in detail.
Add a ultraviolet-curing paint for nano bamboo carbon powder, be made up of the raw material of following weight part (kilogram): polyester acrylate 50, tri (propylene glycol) diacrylate 10, Viscoat 295 5, benzoin dimethylether 4, dihydroxy methylpropane diacrylate 10, lauryl diglycidyl ether 3, hexabromocyclododecane 3, cerium oxide 1, linking agent TAC2, zirconium English powder 3, celestite powder 5, nano bamboo carbon powder 3, auxiliary agent 4;
Described auxiliary agent is made up of the raw material of following weight part (kilogram): diatomite 10, hectorite 5, titanium dioxide 5, epoxy castor oil 3, lemon quintessence oil 0.1, Viscoat 295 4, neopentylglycol diacrylate 3, altax 2, N-BUTYL ACETATE 20; Diatomite is put into calcining furnace to calcine 3-4 hour at 520-540 DEG C by preparation method, takes out, is ground into 50-100 object mixed powder together with hectorite, titanium dioxide; All the other remaining components mixed, be heated to 50-60 DEG C, stir and add mixed powder after 30-45 minute, insulation grinding 1-1.5 hour, to obtain final product.
A kind of ultraviolet-curing paint adding nano bamboo carbon powder of the present invention, be made up of following concrete steps:
(1) polyester acrylate, tri (propylene glycol) diacrylate, Viscoat 295 are put into reactor and stirred, be heated to 75-85 DEG C, stir 15-20 minute;
(2) add all the other remaining components except benzoin dimethylether, continue stirring reaction 30-40 minute, make it to be uniformly dispersed;
(3) be finally cooled to 45-55 DEG C, add benzoin dimethylether, stirring reaction 20-25 minute, after cooling, grinding obtains 20-40 μm of slurry, to obtain final product.
This coating can adopt roller coating, showering, spraying form of construction work construct.Paint spraying on plank the sticking power obtained by above scheme is all better than secondary, resistance to 75% ethanol more than 24 hours, alkaline-resisting more than 24 hours, acidproof more than 48 hours, tolerance 40 degrees below zero and the cold cycling of 40 degree do not ftracture for 10 times, resistance to 15% salt solution more than 60 hours, hardness can regulate between 2H to 3H, and abrasion resistance index is more than 4000 turns.
