preparation example Construction

[0027] The preparation method of the infrared reflective particles comprises the following steps:

[0028] 1) Weighing with the molar ratio of inorganic color pigment and organic pigment in a ratio of 1:1-5;

[0029] 2) Add the organic pigment to the plasticizer, mix evenly, and the consumption of the plasticizer is 4-10 times of the weight of the inorganic color pigment;

[0030] 3) Add the feed liquid obtained in step 2) to the inorganic color pigment, stir, and disperse evenly with the aid of ultrasound;

[0031] 4) Centrifugal filtration to obtain infrared reflective particles; or directly use it as color paste.

[0032] Taking PVC as the base resin as an example, the reflective substrate layer is made of the following components in parts by weight: 100 parts of PVC, 50-120 parts of plasticizer, 1-20 parts of silicon dioxide modified titanium dioxide, 1- 8 parts of foaming agent, 2-5 parts of zinc stearate or calcium stearate, 0.5-10 parts of additives. The reflective s...

Embodiment 1

[0035] An infrared reflective particle, which is obtained by coating iron oxide red with a particle size range of 0.35-0.40 μm and pigment yellow 74, and its preparation method includes the following steps:

[0036] 1) Weigh iron oxide red and pigment yellow 74 at a molar ratio of 1:3;

[0037] 2) Add Pigment Yellow 74 to dioctyl terephthalate, mix well, and the amount of dioctyl terephthalate is 7 times the weight of iron oxide red;

[0038] 3) Add the feed liquid obtained in step 2) to iron oxide red, stir, and disperse evenly with the aid of ultrasound;

[0039] 4) Centrifugal filtration to obtain the pigment of infrared reflective particles

Embodiment 2

[0041] An infrared reflective particle is obtained by coating ultramarine blue with a particle size range of 0.35-0.40 μm through phthalocyanine blue BGS, and its preparation method includes the following steps:

[0042] 1) Weigh ultramarine blue and phthalocyanine blue BGS at a molar ratio of 1:2.5;

[0043] 2) Add phthalocyanine blue BGS to white mineral oil, mix evenly, and the amount of white mineral oil is 7 times the weight of ultramarine blue;

[0044] 3) Add the feed liquid obtained in step 2) to ultramarine blue, stir, and disperse evenly with the aid of ultrasound;

[0045] 4) Centrifugal filtration to obtain the pigment of infrared reflective particles.

Abstract

The invention discloses a low-temperature-rise automotive interior material, which comprises a reflective base material layer and a reflective surface layer, wherein the reflective base material layeris doped with an inorganic white pigment, the reflective surface layer is doped with hollow ceramic microspheres and infrared reflective particles, and the infrared reflective particles are formed bycoating inorganic color pigment crystal nucleuses with an organic pigment. The low-temperature-rise automotive interior material can have rich colors, and is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of automotive interior materials, in particular to a low-rise automotive interior material and a preparation method thereof. Background technique [0002] Existing automotive interior materials are usually composed of resins, pigments and other materials. Under the irradiation of sunlight, they absorb high-energy wavelengths of sunlight such as infrared light waves, which leads to an increase in the temperature of the material, which in turn leads to an increase in the temperature inside the car. . After the temperature in the car rises, it is easy to cause the volatilization of harmful gases, resulting in a decline in the air quality in the car. At the same time, the use of air conditioners to cool down will consume a lot of energy. [0003] The current method of reducing the temperature rise is mainly by adding reflective particles, such as titanium dioxide particles or hollow glass microspheres, to the d...
