Embodiment 1

[0012] 1) Weigh the following raw materials in mass percentage: 40% epoxy resin, 30% polyester resin, 9% triglycidyl isocyanurate curing agent, 8% titanium dioxide, 8% subnanometer barium sulfate, polytetrafluoroethylene Ethylene wax 3%, polyethylene 1%, acetate butyl fiber 1%;

[0013] 2) Melt extrusion: Mix the above raw materials evenly, and then extrude them through a melt extruder;

[0014] 3) Crushing and sieving: After cooling, crush and pass through a 1000-mesh sieve to obtain a powder coating with a particle size of 7-12 μm.

Embodiment 2

[0016] 1) Weigh the raw materials in the following mass percentages: 45% epoxy resin, 35% polyester resin, 6% triglycidyl isocyanurate curing agent, 6% titanium dioxide, 5% subnanometer barium sulfate, polytetrafluoroethylene Ethylene wax 1%, polyethylene 1.5%, acetate butyl fiber 0.5%;

[0017] 2) Melt extrusion: Mix the above raw materials evenly, and then extrude them through a melt extruder;

[0018] 3) Crushing and sieving: After cooling, crush and pass through a 1000-mesh sieve to obtain a powder coating with a particle size of 7-12 μm.

Embodiment 3

[0020] 1) Weigh the following raw materials in mass percentage: 50% epoxy resin, 25% polyester resin, 8% triglycidyl isocyanurate curing agent, 7% titanium dioxide, 6% subnanometer barium sulfate, polytetrafluoroethylene Ethylene wax 2%, polyethylene 1.5%, acetate butyl fiber 0.5%;

[0021] 2) Melt extrusion: Mix the above raw materials evenly, and then extrude them through a melt extruder;

[0022] 3) Crushing and sieving: After cooling, crush and pass through a 1000-mesh sieve to obtain a powder coating with a particle size of 7-12 μm.

[0023] The invention discloses a texture-enhanced powder coating, which is obtained by adding a reasonable proportion of curing agent, titanium dioxide, subnanometer barium sulfate, polytetrafluoroethylene wax, polyethylene, wrinkle agent, etc. to epoxy resin and polyester resin. Raw materials, so that the obtained powder coating particles are uniform and fine, and the paint film formed after spraying has good adhesion, obvious texture and ...

Abstract

The invention discloses a grain reinforced powder coating.The grain reinforced powder coating is prepared from, by mass, 40% to 50% of epoxy resin, 25% to 35% of polyester resin, 6% to 9% of curing agent, 6% to 8% of titanium dioxide, 5% to 8% of nano barium sulfate, 1% to 3% of polytetrafluoroethylene wax, 1% to 1.5% of polyethylene and 0.5% to 1% of furrowing agent.In this way, the coating is even and fine in particle, a paint film formed after the coating is sprayed is good in adhesive force, grain is obvious, and high decoration performance is achieved.

Description

technical field [0001] The invention relates to the field of powder coatings, in particular to a texture-enhanced powder coating. Background technique [0002] Powder coating is a new type of solvent-free 100% solid powder environment-friendly coating. It has the advantages of high coating efficiency, good protection and decorative performance, and has received extensive attention from all over the world, thus achieving sustained and rapid development. [0003] With the high decorative requirements of building materials, furniture and other industries, textured powder coatings have been more and more widely used in anti-theft doors and windows, steel and wood furniture, high-grade metal products and other fields. Textured powder coating meets people's aesthetic requirements with its texture pattern and flower luster. However, the texture of the paint film after spraying of the existing textured powder coating is relatively shallow, the texture effect is not obvious enough, ...
