Abstract
The present invention relates to a kind of powder spray field, and in particular to a kind of powder spray sand streak paint, includes following component according to weight fraction：Polyester resin 45 60, curing agent 79, floride-free sand streak agent 0.5 1.5, no silicon levelling agent 46, titanium dioxide 10 20, adhesion promoter 5 10, barium sulfate 10 18, bentonite 0.1 0.7, growth agent 0.05 0.5.A kind of powder spray sand streak paint of the present invention, pass through each component in adjustment system, the each component used has abandoned the auxiliary agent of the low-surface-energy such as fluorine-containing and siliceous completely, the surface for adding cured film in allowed limits can, when occurring mass defect on sand streak surface and needing to return spray recoating, the combination on sand streak surface for being conducive to sand streak paint and having been cured.
Description
Technical field
The present invention relates to a kind of powder spray field, and in particular to a kind of powder spray sand streak paint.
Background technology
Sand streak paint is exactly not have the gloss commonly painted after spraying, and touches up with frosted texture, provides various for furniture
The painting effect of change, but when using frosted paint, in order that paint filler may be uniformly dispersed in paint, generally require to use
Substantial amounts of solvent, auxiliary agent, these solvents and auxiliary agent contain substantial amounts of VOC (VOC), and pollution environment, infringement
Painter is healthy, inflammable and explosive, waste petroleum resources, to the preparation of frosted paint and greatly inconvenient and potential using bringing
Harm.
Aluminium shape surface has good barrier propterty and decoration performance after powder spray, by the development of decades,
Spraying aluminum profile technique is gradually improved, and is also improved constantly while spraying yield rate.Generally, if strictly controlling pre-treatment
And spraying coating process, the generation of defective work can be controlled to greatest extent.But due to raw and auxiliary material, extrusion billet, spraying equipment, life
The factor such as environment and employee's sense of responsibility of production, aluminium section bar powder spray one-pass finished qualification rate is extremely difficult to 100%, wherein most
Defect needs reparation of doing over again.
It has been observed that when sand streak surface occur mass defect need return spray recoating when, it some times happens that return sprayed coating with it is previous
There is delamination between road sand streak coating.
The content of the invention
In order to solve when sand streak surface occur mass defect need return spray recoating when, return sprayed coating sand streak coating together with preceding
Between the problem of there is delamination, the invention discloses a kind of powder spray sand streak paint, with good adhesive force is good and phase
Capacitive, when mass defect, which occurs, in sand streak surface needs to return spray recoating, completely eliminates and returns sprayed coating sand streak coating together with preceding
Between delamination.
To realize the purpose of the present invention, the present invention is adopted the following technical scheme that：
A kind of powder spray sand streak paint, includes following component according to weight fraction：
Specifically, above-mentioned polyester resin is saturated carboxyl polyester resin.Saturated carboxyl polyester resin is selected from great Bo Xindas
The saturated carboxyl polyester resin of the H60 models of factory, its acid number is 60mgKOH/g.
Specifically, above-mentioned curing agent is triglycidyl isocyanurate.
Specifically, above-mentioned floride-free sand streak agent is sand streak agent 811.
Specifically, above-mentioned is GLP503 or GLP603 without silicon levelling agent.By that from without silicon levelling agent, on the one hand can subtract
Shrinkage cavity in few system solidification process, on the other hand can not influence the original adhesive force of sand streak paint, moreover it is possible to ensure in sand streak table
There is good adhesion when mass defect needs to return spray recoating in face.
Specifically, above-mentioned adhesion promoter is HF-1.On the one hand adhesive force of the sand streak paint to base material can be improved, together
When, when occurring mass defect on sand streak surface and needing to return spray recoating, it can also be ensured that sand streak paint is to the sand streak surface that has been cured
Keep good adhesive force.
Specifically, above-mentioned growth agent is growth agent EDF.The carried charge of powder particle when can effectively improve spraying, so that
Powder in raising.In addition, leaking away the electric charge of workpiece surface in time when dusting, so as to overcome electrostatic screening effect, make workpiece
Inner surface is easy to upper powder.
Specifically, above-mentioned barium sulfate is 2500-3000 mesh blanc fixes., can be with titanium from the barium sulfate of high mesh number
White powder coordinates, to adjust the texture of sand streak paint film.
The device have the advantages that：
(1) a kind of powder spray sand streak paint of the invention, with the addition of adhesion promoter, on the one hand can improve sand streak paint
To the adhesive force of base material, meanwhile, occur on sand streak surface mass defect need return spray recoating when, it can also be ensured that sand streak paint is to
Cured sand streak surface keeps good adhesive force.
(2) a kind of powder spray sand streak paint of the invention, by each component in adjustment system, each component used is complete
The auxiliary agent of the low-surface-energy such as fluorine-containing and siliceous has been abandoned, the surface energy of cured film has been added in allowed limits, in sand streak table
When there is mass defect and needs to return spray recoating in face, the combination on sand streak surface for being conducive to sand streak paint and having been cured.
(3) the sand streak paint adhesive force for preparing of the present invention compared with it is strong, paint film is plentiful, hardness is high, spraying using simple, sand streak easily into
Type and uniform, heavy metal free, environmental protection, security performance are higher.
