Embodiment 1

[0042] 34 parts by weight of thermosetting acrylic resin, 20 parts by weight of epoxy resin and 17 parts by weight of methylphenyl silicone resin were mixed at a rotation speed of 300 r / min to obtain a first mixture. Next, the above-mentioned first mixture was mixed with 12 parts by weight of pigments and fillers, 7 parts by weight of auxiliary materials and 68 parts by weight of water at a rotation speed of 800 r / min to obtain a second mixture. Then, the above-mentioned second mixture was mixed with 6 parts by weight of fragrance under the conditions of 50° C. and 1400 r / min to obtain a coating.

[0043] Among them, the pigments and fillers contain phthalocyanine blue and lithopone. The auxiliary material contains butadienyl triethoxysilane, potassium lignosulfonate, cuprous oxide, water glass and EPDM rubber in a weight ratio of 4.3:3:0.05:1:0.5. The fragrance contains essential oil and an air freshener at a weight ratio of 1:0.7, the essential oil contains lemon essential ...

Embodiment 2

[0045] 46 parts by weight of thermosetting acrylic resin, 27 parts by weight of epoxy resin and 26 parts by weight of methylphenyl silicone resin were mixed at a rotation speed of 500 r / min to obtain a first mixture. Next, the above-mentioned first mixture was mixed with 18 parts by weight of pigments and fillers, 12 parts by weight of auxiliary materials and 88 parts by weight of water at a rotation speed of 1200 r / min to obtain a second mixture.

[0046] Among them, the pigments and fillers contain phthalocyanine blue, toluidine red and lithopone. The auxiliary material contains γ-glycidyl etheroxypropyl trimethoxysilane, potassium lignosulfonate, cuprous oxide, water glass and EPDM rubber with a weight ratio of 5:3.6:0.07:1.2:0.8.

[0047] Linseed essential oil and sweet-scented osmanthus essential oil were used as essential oil raw materials. After ultrafine grinding, supercritical fluid extraction was performed at 40°C and 30 MPa for 8 hours, and then distilled to obtain ...

Embodiment 3

[0050] 40 parts by weight of thermosetting acrylic resin, 23.5 parts by weight of epoxy resin and 21.5 parts by weight of methylphenyl silicone resin were mixed at a rotation speed of 400 r / min to obtain a first mixture. Next, the above-mentioned first mixture was mixed with 15 parts by weight of pigments and fillers, 9.5 parts by weight of auxiliary materials and 78 parts by weight of water at a rotation speed of 1000 r / min to obtain a second mixture.

[0051] Among them, the pigments and fillers contain iron yellow and lithopone. The auxiliary material contains a mixture of butadienyl triethoxysilane and γ-aminopropyl triethoxysilane with a weight ratio of 4.75:3.3:0.06:1.1:0.65, potassium lignosulfonate, cuprous oxide, water glass and EPDM.

[0052] Hypromellose is dissolved in an alcoholic solution to obtain a sustained release formulation. Peony essential oil, loofah essential oil and cucumber essential oil are used as essential oil raw materials, after ultrafine grindi...

Abstract

The invention relates to a coating for an air-conditioning housing and a preparation method of the coating and belongs to the field of high polymer materials. The coating comprises thermoset acrylic resin, epoxy resin, methyl phenyl silicone resin, pigments and fillers, water, a fragrant material and an auxiliary material, wherein the auxiliary material comprises a silane coupling agent, potassium lignosulphonate, cuprous oxide, water glass and an ethylene propylene terpolymer; the fragrant material comprises essential oil and an air freshener. According to the coating, indoor air can be effectively improved, the housing can be prevented from yellowing and ageing after an air conditioner is used for a relatively long period of time. The thermoset acrylic resin, the epoxy resin and the methyl phenyl silicone resin are mixed at the rotating speed of 300-500r/min, mixed with the pigments and fillers, the auxiliary material and the water at the rotating speed of 800-1200r/min, and then mixed with the fragrant material at 50-60 DEG C at the rotating speed of 1400-1500r/min to obtain the coating. The preparation method is simple and the process is easy to control.

Description

technical field [0001] The invention relates to the field of polymer materials, and in particular to a coating for an air conditioner casing and a preparation method thereof. Background technique [0002] Coating is a kind of solid film that can be coated on the surface of objects by different construction techniques to form a solid film with firm adhesion, certain strength and continuity. The film formed in this way is commonly called a coating film, also known as a paint film or a coating. Paint is a kind of paint, which refers to a class of liquid or solid materials that can form a thin film on the surface of an object under certain conditions to protect, decorate or have other special functions (insulation, rust prevention, etc.). Because most of the early paints used vegetable oil as the main raw material, they are also called paints. Now synthetic resins have mostly or completely replaced vegetable oils, so they are called paints. Coatings are not liquid, and powder...
