Background technology
For powdery paints because it is free of organic solvent, the feature of environmental protection is good, storage, convenient transportation the advantages that be widely used in each neck
Domain, in some special occasions, higher requirement is proposed to the wearability of powdery paints, but be limited to plexiglas temperature and
Limited without solvent operation viscosity, prior art does not have the powdery paints supply market of high-wear resistance also, and prior art passes through
Film thickness is reduced to improve coating abrasion performance, while the protecting function and appearance requirement of coating can be reduced, is led in the prior art
Cross and high-hardness inorganic compound is added in resin body material to improve wearability, but in preparation process, abrasion-proof particle is same
Sample can scratch equipment in process, cause equipment consumption rate high, and equipment is more easily damaged, and causes production cost higher, should
With greatly being limited, therefore, it is necessary to the wearability of powdery paints is improved by other means, and can meets powder coating
Protective value and appearance design requirement.
The content of the invention
The purpose of the present invention is to be directed to the problem of existing, there is provided a kind of scratch resistance hardening agent for powdery paints.
The present invention is achieved by the following technical solutions：A kind of scratch resistance hardening agent for powdery paints, it is a kind of
Tissuemat E modified materials, its preparation method comprise the following steps：
（1）In magnetic field intensity it is 600-800Gs by graphene, while the ultrasonic disperse 1-2 hours under ultrasound condition, obtain graphite
Alkene processing material is standby；
（2）It will add in sealable ball mill after Tissuemat E, vanadium diboride, graphene processing material mixing, lead to after vacuumizing
Enter temperature for 75-85 DEG C, the ball milling 4-6 hours under conditions of quality of the ball mill ratio is 6-8, rotating speed is 200-400 revs/min, i.e.,
.
As further improvement of these options, the graphene is that 5-8 layers are periodically tight with benzene ring structure by the number of plies
Closely packed carbon atom is formed with different way of stacking stackings.
As further improvement of these options, the step（1）Middle ultrasound condition is that ultrasonic frequency is 86-96W.
As further improvement of these options, usage amount of the scratch resistance hardening agent in powdery paints is total for its
The 1.2-1.8% of weight.
As further improvement of these options, the application method of the scratch resistance hardening agent is directly and powdery paints
The mixing of other raw materials, common extrusion after melting.
The present invention has advantages below compared with prior art：Scratch resistance hardening agent preparation method is simple in the present invention, condition
It is easily controlled, less addition can increase the surface slip of powdery paints, mitigate frictional force, and then play scratch resistant
Powder coating product hardness, can be obviously improved by effect, while will not excessively occur because of the addition of scratch resistance hardening agent
The situation that lustrous surface declines, ensure the product quality of powdery paints.
