Description
Technical field
The present invention relates to a kind of wrinkle type powder, especially a kind of wrinkle type powdery paints and preparation method.
Background technology
Wrinkle type coating utilizes the surface tension or compatibility difference of wrinkle agent and sludge ice agent and fused coating, to influence
The melting viscosity and curing rate of coating hold finally so that coating surface generates wrinkle to cover plane powdery paints itself
The shortcomings of shrinkage cavity that easily occurs, pin hole, the defect that substrate surface out-of-flatness is brought can also be covered, there is stronger dicoration.
But since the grain effect that wrinkle type coating is finally presented is influenced by several factors, such as the melt viscosity of coating, gelatinization
Time and powder diameter etc. can all have an impact the grain effect of wrinkle；Meanwhile carrying out coating using existing sludge ice agent
When spraying, texture is uneven, and recycling powder grain effect is unstable.Therefore, there is dope layer chill mark lines for existing technology
Manage the undesirable problem of effect.
Invention content
The object of the present invention is to provide a kind of wrinkle type powdery paints and preparation methods.The present invention has and can improve
The characteristics of effect of coating surface wrinkle texture.
Technical scheme of the present invention：A kind of wrinkle type powdery paints, the powdery paints by following mass parts raw material
Composition：
Epoxy resin, 22-26 parts；Polyester resin, 35-40 parts；Wrinkle agent, 0.08-0.12 parts；Titanium dioxide, 0.3-0.6
Part；Carbon black, 0.4-0.6 parts；Iron oxide red, 1.8-2.4 parts；Magenta, 0.1-0.3 parts；Imidazoles catalyst, 0.015-0.025 parts；It fills out
Material, 35-38 parts；Sludge ice agent, 0.18-0.22 parts；
The sludge ice agent includes additional sludge ice agent and Nei Jia sludge ice agents, and between additional sludge ice agent and interior plus sludge ice agent
Mass ratio is 4.2:1-3.5:1；
The interior plus sludge ice agent is made of the raw material of following mass parts：Perfluor alkyl ethyl acrylate, 70-80 parts；
Polyamide wax, 15-35 parts, cation nanometer porous oxide dispersion, 1-2 parts；
The additional sludge ice agent is made of the raw material of following mass parts：Modified polyacrylate, 75-85 parts；Hydrogenate nettle
Sesame oil, 12-20 parts；3-8 parts of lauryl sodium sulfate.
In a kind of wrinkle type powdery paints above-mentioned, the modified polyacrylate is made of the raw material of following mass parts：
Methyl methacrylate, 30-36 parts；31-35 parts of butyl acrylate；Hydroxypropyl acrylate, 8-10 parts；Three second of gamma-amino propyl
Oxysilane, 1.5-2.5 parts；Glycidyl methacrylate, 18-22 parts；Initiator, 0.15-0.25 parts；Emulsifier, 2-5
Part；Dimethylol urea, 2-3 parts.
In a kind of preparation method of wrinkle type powdery paints above-mentioned, include the following steps：
The raw material of each component in addition to additional sludge ice agent is mixed, obtains coating compound by the first step in proportion；
Coating compound is sent into double screw extruder and carries out material extrusion, obtains applying feed liquid by second step；The twin-screw extrusion
Ji Ith area temperature controls are at 92-96 DEG C, and at 93-95 DEG C, double screw extruder turns for the IIth area temperature control of double screw extruder
Speed control is in 48-52HZ；
Third walks, and but by coating liquid cooling, and carries out compressing tablet process, obtains coating tabletting；The thickness of control coating tabletting exists
2-3mm；
4th step after coating tabletting is crushed and screened, obtains powders A product, then outer plus sludge ice is added in powders A product
Agent is mixed to get powdery paints finished product；The grain size of the powdery paints is 45-60 μm.
In a kind of preparation method of wrinkle type powdery paints above-mentioned, the specific hybrid mode of each component in the step 1
For：Epoxy resin, polyester resin, imidazoles catalyst, titanium dioxide and filler are placed in high-speed mixer and are mixed in proportion, is mixed
At 90-100 DEG C, incorporation time is 2-3 minutes for temperature control when conjunction；It then will with the linear cooling rate of 2.2-2.8 DEG C/s
Temperature is down to 55-65 DEG C, after the completion of cooling, and wrinkle agent is continuously added in high-speed mixer and interior plus sludge ice agent is mixed,
Iron oxide red, magenta and carbon black are then added and continue mixing 3-4 minutes into high-speed mixer so that each group by mixing 1-2 minutes
Divide and is uniformly mixed；Cooled to room temperature obtains coating compound.
