Abstract

The invention provides a temperature control coating with a high heat conduction property and a preparation method thereof. The temperature control coating comprises a paint layer and heat conduction particles doped in the paint layer. The preparation method of the temperature control coating includes the following steps that coating paint is prepared; 5 parts of a surface treatment agent is added into every 100 parts of the coating paint 10 min before spraying or brushing, spraying or brushing is carried out after the surface treatment agent and the coating paint are stirred evenly, standing is carried out for 72 h under the room-temperature ventilation condition for primary curing, and the temperature control coating is formed one week later. By adding the heat conduction filler in the paint, the heat conduction property of the coating is improved, and heat diffusion on the surface of a product is achieved through the coating; by adopting the novel additive with a high heat conduction property, the heat conduction property of the coating is substantially improved, relatively centralized heat is effectively diffused along the surface of the coating, and the temperature control capability is further improved.

Example Embodiment

[0032] Example 1

[0033] This embodiment relates to a method for preparing a temperature control coating with strong thermal conductivity, including the following steps:

[0034] (1) Preparation of raw materials for paint coating: raw materials include 107 room temperature vulcanized silicone rubber, thermally conductive filler particles, KH550 surface treatment agent, and auxiliary material is xylene (thinner).

[0035] (2) The components of typical thermally conductive filler particles are as follows:

[0036] 1) Conductive and thermally conductive filler particles: based on the mass of 107 RTV silicone rubber as 100 parts, 40 parts of 1000 mesh spherical graphite and 20 parts of 80 mesh flake graphite are required.

[0037] 2) Insulating thermally conductive filler particles: based on 100 parts of 107 room temperature vulcanized silicone rubber, 60 parts of cubic boron nitride of 500 mesh or more are required.

[0038] (3) The typical paint preparation steps are as follows:

[0039] 1) In a 1000ml jar, add 250g of 107 room temperature vulcanized silicone rubber, 150g of thermally conductive filler particles (typically granular graphite), and 400g of xylene in sequence.

[0040] 2) Manually stir slowly with a glass rod in the same direction for 5 minutes until the raw materials are initially uniformly dispersed.

[0041] 3) Place the jar under the stirrer, the stir bar of the stirrer goes deep into the jar, and the stir bar is adjusted stably. After there is no risk of being thrown out, turn on the stirrer and stir at the speed for more than 10 minutes and slowly increase to 1500r /min~1600r/min, stirring for 4 hours.

[0042] 4) Store the paint in a jar, and store it in a cool, explosion-proof equipment for later use.

[0043] (4) The preparation steps of typical paint before painting are as follows:

[0044] Add 5 parts of positive KH550 surface treatment agent per 100 parts of paint. Add it 10 minutes before spraying or brushing, and manually stir for 5 minutes to mix.

[0045] (5) Coating curing: After spraying, let it stand for 72 hours under room temperature and ventilation conditions for preliminary curing, and the performance will reach the best one week later.

[0046] Compared with the prior art, the present invention has the following beneficial effects:

[0047] 1. Solve the problem of heat conduction enhancement under special conditions such as irregular surfaces;

[0048] 2. Highly flexible and operability, greatly improving the implementation efficiency;

[0049] 3. Under the condition of ensuring the basic performance, the method of coating film formation is adopted to greatly reduce the weight of the system;

[0050] 4. It has convenient maintenance performance.
