Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the durability of the existing aerosol spray paint is not good, and with the prolongation of the service time, the paint film sprayed on the wooden furniture may appear to fall off, resulting in damage to the wooden furniture. The repair effect is not long-lasting, so the existing aerosol spray paint for repairing wooden furniture still needs to be improved

Embodiment 1

[0038] The invention discloses a water-based aerosol spray paint for repairing wooden furniture, which is prepared according to the following steps:

[0039] S1. First carbamoyl chloride, stannous octoate and acetic anhydride and epoxy resin are placed in an open batching device, and at a temperature of 40 ° C, stir evenly to obtain an epoxy resin mixture;

[0040] S2. Then place the acrylic resin emulsion and the epoxy resin mixture material, oxidized polyethylene and pigment in the open batching device, stir evenly under the condition of 50 ℃, put into the three-roll machine roll mill twice; Then add curing agent and diluent under stirring state, stir for 30 minutes, cool to room temperature, and obtain a uniform suspension, that is, water-based aerosol spray paint.

[0041] Infrared spectrum detection of the epoxy resin mixture in S1, at 3431cm -1 Vibration absorption peaks are detected at , which proves that the amino group has been loaded on the epoxy resin; among the co...

Embodiment 2

[0043] The difference from Example 1 is that the present invention discloses a water-based aerosol spray paint for repairing wooden furniture, which is prepared according to the following steps:

[0044] S1. First carbamoyl chloride, stannous octoate and acetic anhydride and epoxy resin are placed in an open batching device, and the temperature is 45° C., and stirred evenly to obtain an epoxy resin mixture;

[0045] S2. Then place the acrylic resin emulsion and the epoxy resin mixture material in S1, oxidized polyethylene and pigments in an open batching device, stir evenly at a temperature of 60° C., and put it into a three-roller mill for two times; Then add curing agent and diluent under stirring state, stir for 35 minutes, and cool to room temperature to obtain a uniform suspension, that is, water-based aerosol spray paint.

[0046] The content of each component is shown in Table 1 below.

Embodiment 3

[0048] The difference from Example 1 is that the present invention discloses a water-based aerosol spray paint for repairing wooden furniture, which is prepared according to the following steps:

[0049]S1. First carbamoyl chloride, stannous octoate and acetic anhydride and epoxy resin are placed in an open batching device, and at a temperature of 42 ° C, stir evenly to obtain an epoxy resin mixture;

[0050] S2. Then place the acrylic resin emulsion and the epoxy resin mixture material in S1, oxidized polyethylene and pigments in an open batching device, stir evenly at a temperature of 58° C., and put it into a three-roller mill for two times; Then add curing agent and diluent while stirring, stir for 33 minutes, cool to room temperature, and obtain a uniform suspension, that is, water-based aerosol spray paint.

[0051] The content of each component is shown in Table 1 below.

Abstract

The invention relates to the technical field of aerosol spray paint, and discloses a water-based aerosol spray paint for repairing wooden furniture. The water-based aerosol spray paint includes the following components in parts by weight: 40-60 parts of acrylic resin emulsion; 8-12 parts Epoxy resin; 3-4 parts of oxidized polyethylene; 2-4 parts of curing agent; 0.3-0.6 parts of thinner; 0.6-1.2 parts of pigment. The present invention has the following advantages and effects: acrylic resin has the characteristics of light color, high transparency, color retention, weather resistance, heat resistance, corrosion resistance, strong adhesion, hardness, toughness, etc., and epoxy resin has excellent bonding performance and Physical and mechanical properties, the combination of the two can improve the overall performance of the spray paint, and can improve the adhesion of the paint film after the spray paint is sprayed on wooden furniture, thereby effectively improving the durability of the paint film.

Description

technical field [0001] The invention relates to the technical field of aerosol spray paint, in particular to a water-based aerosol spray paint for repairing wooden furniture. Background technique [0002] The surface of wooden furniture is prone to some damage during use. In order to prevent the repaired surface from being incompatible with the original surface of the furniture and achieve a better repair effect, the existing repair method usually uses aerosol spray paint for partial repair; aerosol spray paint Agents are generally composed of resins, pigments, additives and solvents. Water-based paints mainly use water or ethanol as solvents. They are non-toxic and environmentally friendly, do not contain harmful solvents such as benzene, are environmentally friendly, and are safe and convenient to use. Global consensus, with its environmental protection concept and excellent quality, it has gained good market recognition. The aerosol spray paint currently used generally a...
