Abstract
The invention relates to infrared-reflective PVC artificial leather which comprises a surface layer and a foaming layer, wherein infrared-reflective color paste is added into the surface layer and the foaming layer, and the infrared-reflective color paste is made of chromium iron oxide. The PVC artificial leather according to the present invention can be applied to automotive interiors, and has significantly improved cooling effects compared to conventional materials.
Description
Technical Field
The invention relates to infrared-reflective PVC artificial leather which can be applied to automotive interior and has a cooling effect under solar radiation.
Background
Polyvinyl chloride (i.e., PVC) is an important raw material in the production and development of artificial leather, and is widely used in automotive interiors. For artificial leather, sufficient color hiding power is generally required to improve the conventional demands of leather such as light fastness, heat resistance, and stain resistance. For this reason, conventional PVC interior materials mostly use conventional black pigments such as carbon black to achieve color hiding of leather. Especially in summer, the interior of the automobile may reach high temperatures of up to 75 to 85 ℃ under the sun exposure, and in such high temperature conditions, the conventional PVC interior material has disadvantages in that: the body feels uncomfortable when being in direct contact with the PVC interior material; the smell in the car is relatively bad, and harmful emission substances are increased; the aging of the PVC interior material is accelerated at high temperature.
In order to improve the heating problem of the PVC leather, a plurality of researches are carried out in the prior art.
Korean patent application KR20180091173 discloses artificial leather for automotive interiors, in which it is mentioned that glass bubbles, which have near-infrared reflectivity and low heat capacity, are added in surface treatment of the outermost layer, and near-infrared reflection type pigments are added in the PVC skin layer.
Patent application WO2018012691 discloses artificial leather for automotive interiors, comprising an infrared-transmitting upper layer and an infrared-reflecting lower layer, wherein inorganic reflective pigments, such as titanium dioxide, iron oxide and the like, are added to the infrared-reflecting lower layer.
Chinese patent CN101624783B discloses a PVC artificial leather with high infrared reflectivity, comprising: a transmissive surface layer comprising a black pigment mixture of a perylene black pigment and a carbon black pigment; a reflective foam layer comprising a white titanium dioxide pigment and a PVC resin; a reflective substrate layer comprising polyester fibers, the polyester fibers comprising white titanium dioxide pigment.
Chinese patent CN102275348B discloses an automobile interior decoration material in which a skin material has an infrared ray reflective layer as a lower layer and a thin appearance layer coated on the infrared ray reflective layer as an upper layer. A black pigment having infrared transmittance is added to the appearance layer, and incident infrared rays are transmitted through the appearance layer, reflected by the infrared reflection layer, and diffused.
The cooling type automobile interior decoration field has the potential of further research and development and improvement, and particularly, the color requirement of leather must be met while the cooling effect is ensured, and the adverse effect of white pigment such as titanium dioxide on the color of the leather is avoided. It is also necessary to ensure the mechanical performance requirements for the interior of the vehicle.

Based on the prior art, the invention aims to provide the infrared-reflective PVC artificial leather. The PVC artificial leather can be applied to automotive interiors, meets the requirement that the leather has an expected dark color, and has a good cooling effect at a high temperature of solar radiation.
In order to achieve the technical purpose, the invention provides infrared-reflective PVC artificial leather which comprises a surface layer and a foaming layer, wherein infrared-reflective color paste is added into the surface layer and the foaming layer, and the infrared-reflective color paste is made of iron oxide chromium.
The temperature change of the surface of the material depends on the reflectivity of the material. The higher the reflectivity of the material, the more solar radiant energy is reflected and the smaller the magnitude of the surface temperature increase. The invention uses infrared reflection color paste to replace the traditional color paste added in the skin layer and the foaming layer, such as carbon black. Taking a black material as an example, in a visible light region of 350nm to 750nm, the reflection spectrogram of the infrared reflection color paste is similar to that of the traditional color paste, and the appearance of the material has no macroscopic change; and in the near infrared region of 750nm to 2500nm, compared with the traditional color paste, the infrared reflection color paste has smaller absorption and slower temperature increase. Because the heat energy carried by the near infrared region accounts for more than 53% of the total solar heat energy radiation amount, the key for realizing the cooling is to improve the heat energy radiation of the near infrared region. Therefore, the infrared reflection color paste is used for replacing the traditional black color paste, so that the low-temperature effect of the PVC material under the high-temperature solar radiation can be well achieved.
The invention adopts iron oxide chromium pigment as the material of infrared reflection color paste, which belongs to black color paste. In the near infrared region, conventional black pigments such as carbon black maintain a low reflectance of about 5%, and thus reflect less solar radiation, resulting in a sharp rise in temperature; although the white pigment has very high reflectivity and strong reflectivity, the temperature rise is little, however, the white pigment can not meet the covering requirement of the automobile interior leather for the color; the black infrared reflection color paste well balances two requirements of reflectivity and color covering, can realize high reflectivity of more than 45 percent which is close to that of the conventional white pigment in a near infrared region, and simultaneously ensures good leather color covering. Compared with other conventionally known infrared reflection additives, for example, the manganese ferrite (manganese iron black) has an infrared reflectivity of 12%, and the ferrochrome nickel (black) has an infrared reflectivity of 13%, the iron chromium oxide adopted by the invention has a higher infrared reflectivity, and thus a significantly more excellent reflection effect can be realized. It is critical that the chromium iron oxide be able to achieve a satisfactory colour while ensuring high reflectance.
According to one embodiment of the present invention, the skin layer comprises, in addition to the infrared-reflective color pastes, other color pastes in which the infrared-reflective color paste comprises 80% to 90% of the total weight of the color pastes in the skin layer, for example 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90% or a specific gravity in the range between any two of these values. Accordingly, the other color pastes constitute from 10% to 20% of the total weight of color pastes in the skin layer, for example 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20% or a specific gravity within a range between any two of these values. Other color pastes, such as phthalocyanine blue, red iron oxide, etc., are used to adjust the overall color paste color to match the target color. When the infrared reflection color paste in the surface layer accounts for less than 80 percent of the total weight of the color paste, the cooling effect is poor, and the expected black color cannot be blended; when the infrared reflecting color paste in the skin layer comprises more than 90% of the total color paste weight, the desired different colors may not be achieved. Based on the content range, the target color can be blended on the basis of improving the use proportion of the reflection color paste as much as possible. This makes it possible to improve the surface reflection performance of leather and to satisfy the conventional requirements of leather, such as the desired deep color, light fastness, heat resistance, and stain resistance.
According to one embodiment of the present invention, the infrared-reflective color paste in the foamed layer comprises at least 80%, such as 80%, 85%, 90%, 95%, 100% or a range between any two of these values, of the total weight of the color paste in the foamed layer. Preferably, the infrared reflection color paste in the foaming layer accounts for at least 90 percent of the total weight of the color paste in the foaming layer, and more preferably 100 percent. The foaming layer has little influence on the color of the surface of the leather, so that when all the color paste in the foaming layer is infrared reflection color paste, the optimal cooling effect can be achieved.
According to one embodiment of the present invention, the skin layers comprise, based on the total weight of the skin layers:
42% -57% PVC powder, e.g., 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57% or a PVC powder in a range between any two of these values,
35% -52% plasticizer, e.g., 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52% plasticizer or a range between any two of these values,
0.1% to 3.5% of a stabilizer, e.g., 0.1%, 0.5%, 1.0%, 2.0%, 3.0%, 3.1%, 3.2%, 3.3%, 3.4%, 3.5% or a stabilizer within a range between any two of these values,
2% -15% of an infrared-reflecting color paste, e.g., 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, or a range between any two of these values, and
0-5% of other color pastes, for example 0%, 1%, 2%, 3%, 4%, 5% or other color pastes in a range between any two of these values.
When the content of the infrared reflection color paste is too low, the expected cooling effect cannot be realized. When the content of the infrared reflection color paste is too high, other mechanical properties of the PVC artificial leather, such as abrasion resistance and flexing resistance, may be reduced, thereby failing to satisfy the mechanical requirements of the automotive interior.
According to one embodiment of the present invention, the foamed layer comprises, based on the total weight of the foamed layer:
37% -55% PVC powder, e.g. 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 54%, 55% or a PVC powder in a range between any two of these values,
32% -52% plasticizer, e.g., 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52% or a range between any two of these values,
0.07% to 3.3% stabilizer, e.g., 0.07%, 0.1%, 0.5%, 1.0%, 1.5%, 2.0%, 2.5%, 3.0%, 3.3% or a stabilizer within a range between any two of these values,
0% to 6% of an infrared-reflecting color paste, for example 0%, 1%, 2%, 3%, 4%, 5%, 6% or an infrared-reflecting color paste in the range between any two of these values,
0.8% -4.5% of a blowing agent, e.g., 0.8%, 1.0%, 2.0%, 3.0%, 4.0%, 4.5% or a range between any two of these values, and
1% to 5% flame retardant, e.g., 1%, 2%, 3%, 4%, 5% or a range between any two of these values.
