Description
Technical field
The present invention relates to a kind of car paints more particularly to a kind of automobile heat insulation coating and preparation method thereof.
Background technique
Tool of the automobile as people's outdoor activities, the probability for receiving extraneous strong illumination is very high, and the time is especially long, special
It is not the arriving with torridity summer, outdoors, sunlight can be described as directly heating vehicle vehicle driving；Even if vehicle
Air-conditioning is inside opened, cooling effect is also bad, so that energy consumption is especially high.The heat-insulated means of automobile tradition are with the resistance of the materials such as heat insulating mattress
Insulating heat conduction holes, but under the direct irradiation of sunlight, automotive lacquer position is brought rapidly up, and the heat of generation makes car by heat transfer
Temperature also increases, this is because present automotive metal shell only only has one layer of exterior paint, there is no dedicated thermal insulation layer,
That is traditional automobile heat insulation facility can not reduce heat to interior propagation.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, provide a kind of apply under automotive lacquer layer
Adiabator layer above face, metal shell layer, the good heat-insulation effect for the thermal insulation material that adiabator layer of the invention uses, energy
Enough effective reduction energy consumptions.
In order to solve the above technical problems, technical solution proposed by the present invention are as follows: a kind of automobile heat insulation coating, including 25-40
Part water, 20-40 parts of coating resins, 3-9 parts of vacuum ceramic pearls and 1-3 parts of silica aerogel powders；The vacuum ceramic pearl
Partial size between 5-100nm.
Above-mentioned automobile heat insulation coating, it is preferred that the vacuum ceramic pearl of 5-30nm accounts for all vacuum ceramic pearl specific gravity
40% or more.
Above-mentioned automobile heat insulation coating, it is preferred that the vacuum ceramic pearl of 30-60nm accounts for all vacuum ceramic pearl specific gravity
30% hereinafter, the vacuum ceramic pearl of 60-100nm accounts for the 30% or less of all vacuum ceramic pearl specific gravity.
Above-mentioned automobile heat insulation coating, it is preferred that further include 3-9 parts of gallium, the granularity of the gallium is 400-
500 mesh.Gallium mainly plays the role of catalysis.
Above-mentioned automobile heat insulation coating, it is preferred that further include 1-3 parts of surfactants.
Above-mentioned automobile heat insulation coating, it is preferred that the surfactant includes fatty glyceride, fatty acid sorb
Smooth, polysorbate, alkyl phenol polyoxyethylene ether, high-carbon fatty alcohol polyoxyethylene ether, polyoxyethylene carboxylate, fatty acid methyl ester
One or more of ethoxylate, sorbitan ester.The addition of surfactant enables to vacuum ceramic pearl to exist
Disperse more uniform in solution, so that coating of the invention, after film forming, vacuum ceramic pearl can fill more nanoscales
Micropore.
Above-mentioned automobile heat insulation coating, it is preferred that the coating resin includes styrene acrylic coating resin, dipentaerythritol six
One of acrylate or two kinds.
Above-mentioned automobile heat insulation coating, it is preferred that further include 10-20 parts of additives, the additive include dispersing agent, at
Film auxiliary agent, defoaming agent and levelling agent.
A kind of preparation method of automobile heat insulation coating, includes the following steps, 1) 3-9 parts of vacuum ceramic pearls are put into 1-3
It in part surfactant, stirs evenly, opens ultrasonic wave stirring simultaneously when stirring；It is stand-by after mixing evenly；
2) 25-40 parts of water and 20-40 parts of coating resins are mixed and is stirred evenly；
3) solution of step 1) is added into step 2), and stirs evenly, opens ultrasonic wave simultaneously when stirring
Stirring；
4) 1-3 parts of silica aerogel powders are added in the solution of step 3), and stir evenly, stirring when
It waits while opening ultrasonic wave stirring.
The preparation method of above-mentioned automobile heat insulation coating, it is preferred that the step 4) be 0-5 DEG C at a temperature of complete
's.
The lower surface that automobile heat insulation coating of the invention is uniformly coated in automobile exterior paint forms one layer of thermal isolation film；At this
Heat effectively can be blocked in automobile external under the action of layer thermal insulation layer.
In the present invention, exist inside the thermal isolation film that thermal insulation material is formed it is a large amount of nanometer level microporous, when there is no vacuum pottery
This nanometer level microporous aperture is in 120nm or so when porcelain bead, and gas molecule is flat in heat-insulated membrane material of the invention
The typical sizes being freely formed are about 90nm；The heat that gas molecule can be collided in thermal isolation film in this way is transmitted, therefore
Do not have vacuum ceramic pearl there are when thermal isolation film of the invention thermal coefficient it is comparatively relatively high, in 1.0W/mK
Left and right.
It joined the vacuum ceramic pearl of 10-100nm in the present invention, it is micro- that vacuum ceramic pearl is distributed in the nanoscale in thermal isolation film
In hole, the nanometer level microporous aperture inside thermal isolation film of the invention is allowed in this way and is less than what gas molecule was averagely freely formed
Typical sizes have thus freezed the collision of the gas molecule in thermal isolation film, and this makes it possible to effectively reduce leading for thermal isolation film
Hot coefficient.In order to preferably understand the principle of the present invention, the heat transfer modes of gas, liquid and solid will be carried out below
It explains.
The principle of " thermal conduction study " is taught that, when heat can be transmitted to low-temperature space from high-temperature region, the transmitting (speed of heat
And quality) many factors are depended on, the insulation material layer in cold and hot region can prevent the transmitting and loss of heat.Any material
The thermal coefficient of material is a kind of physical index for describing material thermal heat transfer capability itself, and the thermal coefficient of in general certain material is got over
It is low, then its heat-insulating property is better.
Heat transfer in solid, liquids and gases is a kind of warm-up movement of the molecular level of material, and this warm-up movement passes through
Kinetic collision between atom and molecule transmits.
Convection current between gas and liquid is a kind of mass motion of flowing, this is because high-temperature area is with lower close
Caused by the trend that degree causes fluid to rise.
Radiation ray is an energy electromagnetic energy, it does not need any intermediate medium and becomes more after through vacuum
Effectively.In a word, three kinds of heat transfer mechanism can act on simultaneously, be achieved in the effect of all heat transmitting.
In the present invention, heat transfer is mainly kinetic collision and radiation, and radiates and do not need any medium；Therefore it to reduce
Radiation is extremely difficult.The gas molecule collision in thermal isolation film can largely be freezed in the present invention.Therefore it can effectively drop
The thermal coefficient of low material.
