Abstract
The invention discloses a kind of pure polyester composite powder coatings, include the component of following weight：40 65 parts of 17 32 parts of 120 130 parts of saturated polyester resin, 18 24 parts of isocyanate-epoxy propyl alcohol ester, dimethyl silicone polymer or alkyl-modified organosiloxane, 24 parts of ionic surfactant, 46 parts of bloom wax, 49 parts of antioxidant and filler.The pure polyester composite powder coatings adherence of the present invention is good, mechanical performance is good, film is smooth, gloss is high, chemicals-resistant and decay resistance, the product painting for being adapted to long-term outdoor exposure, possess good outdoor durable energy.
Description
Technical field
The present invention relates to art of powder coatings, and in particular to a kind of pure polyester composite powder coatings.
Background technology
Powdery paints is a kind of new to be free of the solid powdery coating of solvent 100%.With it is solvent-free, pollution-free, can return
Receive, environmental protection, save the energy and resource, reduce labor intensity with coating machinery intensity it is high the features such as.In the prior art, its powder applies
Material is made up of polyester resin, enclosed type different Fo Er copper diisocyanate, styrax and dibutyltin dilaurate, and its shortcoming is
Physics characteristic is poor, coverage effect is poor, is also easy to produce rill, can not meet electrical equipment spraying and top layer protection.I.e. existing powder
Coating covering performance is poor, it is impossible to meets production and living needs.
The content of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned deficiency, there is provided a kind of good formulation for coating material of covering performance.
In order to solve the above-mentioned technical problem, it is carried out by the following technical programs：A kind of pure polyester composite powder coatings,
It is characterised in that it includes the component of following weight：Saturated polyester resin 120-130 parts, isocyanate-epoxy propyl alcohol ester 18-
24 parts, dimethyl silicone polymer or alkyl-modified organosiloxane 17-32 parts, ionic surfactant 2-4 parts, bloom wax 4-
6 parts, antioxidant 4-9 parts and filler 40-65 parts.
As a further improvement on the present invention, the filler is in barium sulfate, silicon powder, the class inorganic filler of titanium dioxide three
One or more kinds of combinations.
As a further improvement on the present invention, pure polyester composite powder coatings, the component of following weight is included：It is full
With 24 parts of 125 parts of polyester resin, 21 parts of isocyanate-epoxy propyl alcohol ester, dimethyl silicone polymer or alkyl-modified organosiloxane,
50 parts of 3 parts of ionic surfactant, 5 parts of bloom wax, 6 parts of antioxidant and filler.
The present invention compared with prior art, has advantages below.
The pure polyester composite powder coatings of above-mentioned formula are taken, cost reduces relative to existing formulation for coating material, product spray
Overall film layer is stable after applying shaping, and adherence is good, and mechanical performance is good, and film is tough and tensile, meets high intensity requirement.The present invention's is pure poly-
Ester composite powder coatings adherence is good, mechanical performance is good, film is smooth, gloss is high, chemicals-resistant and decay resistance, is adapted to
The product painting of long-term outdoor exposure, possesses good outdoor durable energy.
