Embodiment 1

[0031] Put the powdery diatomaceous earth in a suction filter bottle, maintain the temperature of 50-60 ° C, and put n-cosane, n-docosane, n-hexanocane, n-eicosane in another suction filter bottle Alkane and n-tridecane are mixed in a mass ratio of 1:1:1:3, the total mass is 60% of the diatomite mass, and heated to 50-60°C to become liquid, and the two suction filter bottles are connected to each other, and the middle Set up a glass plunger. With the piston closed, vacuumize the diatomite suction filter bottle for 30-40 minutes, open the glass piston, add the mixed alkanes dropwise to the diatomite, and soak for 2 hours to obtain the treated diatomite.

[0032] Weigh aminopropyltriethoxysilane by 2% of diatomaceous earth quality, mix aminopropyltriethoxysilane, ethanol, water according to the mass ratio of 2:7:1 and prepare solution, after the above treatment Diatomaceous earth is placed in a solid mixer, and the silane solution is sprayed on the surface of the filler while s...

Embodiment 2

[0037] Put powdered diatomaceous earth in a suction filter bottle and maintain a temperature of 40-50°C, and mix n-hexacane and n-tridecane in a mass ratio of 1:1 in another suction filter bottle, the total mass It is 70% of the mass of diatomite, and it is heated to 40-50°C to become liquid. Two suction filter bottles are connected to each other, and a glass stopper is set in the middle. With the piston closed, vacuumize the diatomite suction filter bottle for 30-40 minutes, open the glass piston, add the mixed aliphatic hydrocarbons dropwise to the diatomite, and soak for 2 hours to obtain the treated diatomite.

[0038] Weigh aminopropyltriethoxysilane according to 1% of diatomite mass, mix aminopropyltriethoxysilane, absolute ethanol, and water in a mass ratio of 2:7:1 to prepare a solution, and silicon Put the diatomaceous earth into a solid mixer, spray the silane solution on the surface of the filler while stirring, and after stirring for 30 minutes, place the diatomite...

Abstract

The invention discloses a temperature-adjustable polyurethane material for a car cover. The temperature-adjustable polyurethane material is characterized in that a complex phase change material is contained in a polyurethane material formula, and the complex phase change material is prepared by the following steps of adsorbing a phase change material on an inorganic porous material, then spraying an ethanol and water solution of a silane coupling agent, and drying. The polyurethane material is soft polyurethane foam containing the phase change material. The polyurethane material used as an interlayer of the car cover can not only play a protecting role in a car when the car is impacted by foreign objects, but also prevent the in-car temperature of the car parked outside in summer from being too high, and the in-car temperature in winter from being too low.

Description

technical field [0001] The invention relates to the field of polyurethane, in particular to a temperature-adjustable polyurethane material used for car clothing. Background technique [0002] Domestic car ownership is increasing year by year, followed by the shortage of parking spaces, and many cars have to be parked outdoors. This has brought many problems, such as the car is exposed to wind, sun, rain and dust etc. outside, the car finish is aging faster, and the service life is shortened. The use of car covers can solve the above problems very well, but it still cannot solve other problems. For example, the northern region is very cold in winter, and it is very difficult to start the engine cold. In summer, the sun is strong and the temperature is high. It is also high, even if the air conditioner is turned on, it will take a long time to lower the temperature, which not only affects the ride comfort but also wastes fuel. [0003] The warm car clothes currently on the m...
