Embodiment 1

[0026] Premix 610g carboxyl-terminated saturated polyester resin, 46g triglycidyl isocyanurate (TGIC), 250g titanium dioxide, 70g precipitated barium sulfate, 1g antibacterial and antifungal agent, 10g brightener, 10g leveling agent and 3g benzoin; Then, the pre-mixed raw materials are melt-extruded. Melt-extrusion refers to the use of a twin-screw extruder to melt, knead, and evenly disperse the pre-mixed raw materials. The temperature in zone I of the extruder is 115-125°C , the temperature in the II zone of the extruder is 105-115°C; then, the extruded material is crushed and finely crushed after being cooled by a tableting roller. ; Finally, sieve the fine powder coating with a standard sieve.

Embodiment 2

[0028] 570g carboxyl-terminated saturated polyester resin, 43g triglycidyl isocyanurate (TGIC), 250g titanium dioxide, 110g precipitated barium sulfate, 1g antibacterial and antifungal agent, 11g brightener, 12g leveling agent and 3g benzoin are premixed; Then, the pre-mixed raw materials are melt-extruded. Melt-extrusion refers to the use of a twin-screw extruder to melt, knead, and evenly disperse the pre-mixed raw materials. The temperature in zone I of the extruder is 115-125°C , the temperature in the II zone of the extruder is 105-115°C; then, the extruded material is crushed and finely crushed after being cooled by a tableting roller. ; Finally, sieve the fine powder coating with a standard sieve.

Embodiment 3

[0030] 530g carboxyl-terminated saturated polyester resin, 40g triglycidyl isocyanurate (TGIC), 250g titanium dioxide, 146g precipitated barium sulfate, 6g antibacterial and antifungal agent, 12g brightener, 12g leveling agent and 4g benzoin are premixed; Then, the pre-mixed raw materials are melt-extruded. Melt-extrusion refers to the use of a twin-screw extruder to melt, knead, and evenly disperse the pre-mixed raw materials. The temperature in zone I of the extruder is 115-125°C , the temperature in the II zone of the extruder is 105-115°C; then, the extruded material is crushed and finely crushed after being cooled by a tableting roller. ; Finally, sieve the fine powder coating with a standard sieve.

Abstract

The invention discloses an antibiotic powdery paint for aluminium profile and a preparation method thereof. The antibiotic powdery paint comprises carboxyl end group saturated polyester resin, triglycidyl isocyanurate (TGIC), titanium dioxide, precipitated barium sulfate, antibiotic mildew inhibitor, brightener, levelling agent and benzoin. A preparation method comprises steps of batch mixing, fusion extrusion, fragmentation and fine crushing. The antibiotic powdery paint for aluminium profile prepared by the method of the invention has good antibiotic and mildew-resistant effects, long-lasting antibiotic and mildew-resistant effects, good compatibility with main film forming substances in powdery paint and no influence on decorative effect of powdery paint.

Description

technical field [0001] The invention relates to a powder coating and a preparation method of the powder coating, in particular to an antibacterial powder coating for aluminum profiles and a preparation method. Background technique [0002] With the improvement of people's living standards, more and more powder-coated aluminum profiles and aluminum products have entered the construction field, such as: aluminum alloy doors and windows, office supplies, medical appliances, children's toys, protective fences, protective nets, etc. Walking into thousands of households, it is closely related to people. With the enhancement of people's awareness of environmental protection, higher requirements are put forward for the living environment and quality of life. Many antibacterial and antifungal agents have also appeared now. In actual production, antibacterial and antifungal agents can be added by weight percentage with the finished powder coating, or can be added to the raw materials...
