The invention also discloses a method for preparing the doodling prevention powder coating. The powder coating has the characteristics of simple formula, convenient coating and curing, excellent chemical resistance, capability of being erased, convenience for repeated doodling and the like. By changing species and dosage of each component, coatings with different colors and different capacities of washing resistance and doodling prevention can be obtained. The product of the invention can be suitable for indoor and outdoor occasions, and the application range of the product comprises the coating of white boards and public facilities, such as road indication boards, bus stops, newspaper boxes, common supplies and the like.
Description
Technical field
The present invention relates to a kind of powder coating, relate in particular to a kind of doodling prevention powder coating, the invention still further relates to the preparation method of this powder coating simultaneously.
Background technology
Scribble, a kind of so-called artistic expression often is considered to immoral.Will spend millions of dollar and know scribble every year such as country, coulisse, owner.Evidence suggests that the most effectual way that spreads that prevents to scribble is to remove scribble rapidly.
The teaching writing mode of traditional blackboard chalk, dust pollution is serious, and the appearance of blank, blank pen; Solved this problem fully, but blank at present on the market is very short work-ing life, though own can wiping; But can leave a trace, the time, long slightly blank was just ineffective, so need the durable coating of development of new; Be not easy to leave a trace after making the blank pen write to clash, spray paint or oil pike is write when the back is cleared up with solvent and can not be destroyed coating.
Based on above various reasons, anti-doodling paint just arises at the historic moment.Powder coating is a kind of generally acknowledged high efficiency, good film performance, ecological environment-friendly type, Eco-power 4E type coating products.Along with people's is to the progressively attention of environmental protection, problem such as energy-conservation; And make powder coating possess many performances that are beyond one's reach of thinking in early days in the eighties in 20th century to the strict demand of coating technology; Powder coating is the same with other green coatings, has obtained develop rapidly in the whole world.
The appearance of doodling prevention powder coating; Making can be by rapid removing by the scribble of application workpiece surface; And the production of powder coating and coating process can reach zero VOC discharging; Environmentally safe has the characteristics of " economizing the energy, resource-saving, low pollution, high-effect ", thereby has good application and Industry Development Prospect.
Summary of the invention
The object of the present invention is to provide a kind of doodling prevention powder coating, but this powder coating has characteristics such as prescription is simple, convenience, the good fast erasing of chemical resistance are solidified in application, be convenient to scribble repeatedly.
Another object of the present invention is to provide the preparation method of above-mentioned powder coating.
First purpose of the present invention realizes through following technical measures: a kind of doodling prevention powder coating comprises following components in weight portions:

1～20 part of auxiliary agent.
Doodling prevention powder coating provided by the invention is through changing the kind and the consumption of pigment, and therefore the appearance of coat that can obtain varying in color can add pigment according to actual needs in said components.
In the powder coating component of the present invention, described vinyl resin is the glycidyl vinyl resin, and its Tg is between 40～60 ℃, and epoxy equivalent (weight) is between 300～700 (g/eq).
Described vinylformic acid solidifying agent is the representative examples of saturated aliphatic diacid, contains the representative examples of saturated aliphatic diacid of 8 to 16 carbon atoms on the preferred main chain, more preferably dodecyl diprotic acid or tetradecane diprotic acid.
Described mineral filler is white titanium pigment, permanent white, silicon powder or lime carbonate, and preferred Rutile type Titanium Dioxide is like the R706 of Du Pont.
Described auxiliary agent is flow agent and skimmer, wherein flow agent such as P67 etc., skimmer such as st-yrax etc.
Second purpose of the present invention realizes through following technical scheme, a kind of preparation method of doodling prevention powder coating, and it may further comprise the steps:
(a) take by weighing vinyl resin, vinylformic acid solidifying agent, mineral filler and auxiliary agent in proportion, place compounding jar, thorough mixing is also broken;
(b) entering of the material after fragmentation forcing machine is extruded;
(c) material after extruding is packed after compressing tablet, cooling, pulverizing, screening and is promptly got.
Among the above-mentioned preparation method, each component mixing and broken time are 5～10 minutes in the said step (a).
Extrusion temperature in the said step (b) is 80～100 ℃; Described forcing machine adopts two or single screw extrusion machine.
Extrudate in the said step (c) through kibbler pulverize and screening after diameter of particle (equivalent grain size D50) for being 10～100 microns, preferred 20～80 microns, more preferably 30～60 microns.
The coating process of anti-graffiti acrylic powder coating provided by the invention is: be coated on the treated base material with high pressure electrostatic method or fluidized bed process; Solidification value is 150～180 ℃; Be 5～20 minutes set time, can adopt hot baking box or infrared curing stove to be cured.
That powder coating of the present invention has that prescription is simple, application is solidified is convenient, chemical resistance is good, can be erasable fast, characteristics such as be convenient to scribble repeatedly.Through kind and the consumption that changes each component, can obtain the coating of different colours, different wash resistant, anti-graffiti ability.Product of the present invention is applicable to indoor, outdoor, and range of application comprises the application of blank, communal facility such as road direction board, bus station board, newspaper case, institutional furniture etc.
