Problems solved by technology

It can be seen that there are many factors that cause indoor air pollution. On the other hand, what is worrying is that the airtightness of the house is getting better and better. In addition, the wide use of air conditioners has caused a sharp decrease in the indoor air exchange coefficient, causing indoor pollutant gases to be unable to diffuse. Exclusion will inevitably aggravate the accumulation of indoor air pollution and the breeding of bacteria and viruses
[0003] Although, in the past ten years, many

Embodiment 1

[0057] A negative ion release antibacterial powder coating, which is prepared from the following raw materials in mass percentage:

[0058]

[0059]

[0060] The preparation steps are:

[0061] (1) After the raw materials are weighed according to the above ratio, they are mechanically mixed in a mixing pot and melted and extruded to obtain powder flakes;

[0062] (2) Grinding the powder flakes in an air classifying mill to form powder particles, which are separated by sieving.

[0063] Curing process:

[0064] Surface pretreatment of the workpiece (standard aluminum plate) → spraying negative ion release antibacterial powder coating → heating and leveling at 200°C for 5 minutes → curing at 180°C / 10min or 200°C / 5min → workpiece inspection and storage.

Embodiment 2

[0066] A negative ion release antibacterial powder coating, which is prepared from the following raw materials in mass percentage:

[0067]

[0068] The preparation method is the same as in Example 1.

[0069] Curing process:

[0070] Surface pretreatment of the workpiece (standard aluminum plate) → spraying negative ion release antibacterial powder coating → heating and leveling at 200°C for 5 minutes → curing at 180°C / 10min or 200°C / 5min → workpiece inspection and storage.

Embodiment 3

[0072] A negative ion release antibacterial powder coating, which is prepared from the following raw materials in mass percentage:

[0073]

[0074] The preparation method is the same as in Example 1.

[0075] Curing process:

[0076] Surface pretreatment of the workpiece (standard aluminum plate) → spraying negative ion release antibacterial powder coating → heating and leveling at 200°C for 5 minutes → curing at 180°C / 10min or 200°C / 5min → workpiece inspection and storage.

Abstract

The invention discloses a negative ion-released antibacterial powdery paint, which comprises the following raw materials by mass percentage: 20-45% of epoxy resin, 20-45% of polyester resin, 0.7-1.2% of negative ion additive, 0.3-1.5% of nano silver antiseptic; 1.8-3% of functional auxiliary agent, 0-5% of promoter, 5-30% of filling material and 0.8-25% of pigment, wherein the sum mass percentage of the raw material is 100%. The prepared negative ion-released antibacterial powdery paint has the advantages that according to the characteristics of a base material, low solidification temperature can be realized, surface coating of a metal material and a non-metallic material can be satisfied, application scope is wide, negative ions can be effectively released, negative ion effect has long and effective unit function, sterilization effect is obvious, and each performance is excellent.

Description

technical field [0001] The invention relates to a powder coating, in particular to a negative ion releasing antibacterial powder coating. Background technique [0002] In human life, more than 60% of the time is spent indoors, and indoor air quality is very important to human health. In the process of interior decoration, if inferior materials are used, toxic and harmful substances such as formaldehyde, ammonia, benzene, and TDI will be released, which has become the number one killer of people's health. Therefore, the state has formulated ten harmful substances in interior decoration materials Limited standards, green, healthy, and environmentally friendly decoration have become the mainstream of the current home decoration market. Indoor air pollution sources are not only decoration materials and building materials, but also various electrical appliances in the home, such as computers, TVs, refrigerators, washing machines, electric heaters, etc., which fill people's livin...
