Embodiment 1

[0024] In the embodiment of the present invention, a polyester powder coating with bactericidal effect is made of the following components in parts by weight: 60 parts of hydroxyl polyester resin, 9 parts of aliphatic polyisocyanate, 20 parts of green bark extract, 5 parts of anatase nano-titanium dioxide, 1.5 parts of leveling agent SF-7, 0.5 parts of benzoin, 10102 parts of antioxidant, 1 part of ammonium salt, 10 parts of pigment, and 1 part of Abutilon seed extract.

[0025] The preparation method of the described polyester powder coating with bactericidal effect, concrete steps are as follows:

[0026] (1) The preparation of the green skin extract, the steps are as follows: wash the green skin, pulverize, pass through a 40-80 mesh sieve to obtain the green skin powder, then add the green skin powder to 7 times the water of its mass, stir evenly, and obtain a suspension liquid; the suspension is introduced into the ultrasonic extraction equipment for wall-breaking extracti...

Embodiment 2

[0030] In the embodiment of the present invention, a polyester powder coating with bactericidal effect is made of the following components in parts by weight: 55 parts of hydroxyl polyester resin, 12 parts of aliphatic polyisocyanate, 1 part of green bark extract, 10 parts of anatase nano-titanium dioxide, 1.0 parts of leveling agent SF-7, 1 part of benzoin, 10101 parts of antioxidant, 10 parts of ammonium salt, 20 parts of Abutilon seed extract.

[0031] The preparation method of the described polyester powder coating with bactericidal effect is the same as in Example 1.

Embodiment 3

[0033] In the embodiment of the present invention, a polyester powder coating with bactericidal effect is made of the following components in parts by weight: 58 parts of hydroxyl polyester resin, 9 parts of aliphatic polyisocyanate, 7 parts of green bark extract, 8 parts of anatase nano-titanium dioxide, 1.4 parts of leveling agent SF-7, 0.7 parts of benzoin, 10101.7 parts of antioxidant, 3 parts of ammonium salt, 6 parts of pigment, 7 parts of velvet hemp seed extract.

[0034] The preparation method of the described polyester powder coating with bactericidal effect is the same as in Example 1.

Abstract

The invention discloses a polyester powder coating with the sterilizing effect and a preparation method and application thereof.The coating is prepared from, by weight, 55-60 parts of hydroxyl polyester resin, 9-12 parts of aliphatic polyisocyanate, 1-20 parts of a citri reticulatae viride extract, 5-10 parts of anatase nano-titanium dioxide, 1.0-1.5 parts of a flatting agent SF-7, 0.5-1 part of benzoin, 1-2 parts of an antioxidant 1010, 1-10 parts of ammonium salt, 0-10 parts of pigments and 1-20 parts of a chingma abutilon seed extract.The polyester powder coating is prepared through the steps of preparing of the citri reticulatae viride extract, preparing of the chingma abutilon seed extract, mixing and crushing, extruding and sieving.The coating is reasonable in preparation, low in preparation cost, high in finished product activity, good in sterilizing effect and capable of solving a series of problems such as product demulsifying, going bad, mildewing, fermenting and stinking which are caused by bacterial contamination.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to a polyester powder coating with a bactericidal effect and a preparation method and application thereof. Background technique [0002] Powder coating is a new type of solvent-free 100% solid powder coating. It has the characteristics of no solvent, no pollution, recyclable, environmental protection, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film. Powder coating is a completely different form from general coatings, and it exists in the state of fine powder. Because no solvent is used, it is called powder coating. The main features of powder coatings are: harmless, high efficiency, resource saving and environmental protection. There are two types of powder coatings: thermoplastic powder coatings and thermosetting powder coatings. Thermoplastic powder coatings are composed of thermoplastic resins, pigments, fillers...
