Definitions

  • the invention relates to the technical field of artificial leather, in particular to a light-transparent artificial leather and a preparation method therefor, and an incorporation thereof in an automotive interior
  • Artificial leather is a plastic product that looks and feels like leather and can replace leather. Characterized by high flexibility and wear resistance, artificial leather can be widely used for bag production and automotive interior decoration.
  • the main aim of the invention is to provide a kind of light-transparent artificial leather and a preparation method therefor, and an automotive interior, to solve the existing problem of artificial leather.
  • the invention is a method for producing (preparation method) light-transparent artificial leather, and said preparation method comprises the steps of:
  • the particle size of the toner in the light-transparent epidermal layer material is set to 0.5 ⁇ 10nm, e.g.., any of 0.5nm, 1nm, 1.5nm, 2nm, 2.5nm, 3nm, 3.5nm, 4nm, 4.5nm, 5nm, 5.5nm, 6nm, 6.5nm, 7nm, 7.5nm, 8nm, 8.5nm, 9nm, 9.5nm and 10nm.
  • the epidermal layer is a colored layer and has a great blocking effect on light, but if the dosage of the pigment is reduced, the color covering effect will be very poor.
  • the toner in the light-transparent epidermal layer material is a toner having a Nano-particle size, which has a lower blocking effect on light, and can ensure ideal transmittance (of light) of the prepared artificial leather even if a large quantity of toner has to be used for a good color covering effect.
  • the toner utilized in the invention is Nano-sized, and therefore much tinier than other powders, uneven dispersion will be caused if it is mixed with other powders.
  • the toner is made into a light-transparent pigment material first, and then the light-transparent pigment material is mixed with polymer powder, a plasticizer, a stabilizer and an inorganic additive to produce a light-transparent epidermal layer material so as to greatly enhance the dispersible uniformity of the toner.
  • the toner can be mixed with the polymer powder and plasticizer to form a light-transparent pigment material so as to greatly enhance the degree of fusion between the light-transparent pigment material and other powders.
  • a grinding process is added to the preparation process of the light-transparent pigment material so that the toner can be mixed evenly with other powders to prevent agglomeration.
  • the mass ratio of each element in the primary raw materials is as follows: 70 ⁇ 100 portions of toner, for example, 70, 75, 80, 85, 90, 95 or 100 portions; 70 ⁇ 100 portions of polymer powder, for example, 70, 75, 80, 85, 90, 95 or 100 portions; 70 ⁇ 100 portions of plasticizer, for example, 70, 75, 80, 85, 90, 95 or 100 portions.
  • the content of the toner cannot be too high or too low, because excessively high content affects transmittance of the artificial leather while excessively low content affects the color covering effect, so preferably, the mass ratio of the toner in the light-transparent pigment material is set to approximately 37%-40%.
  • the toner comprises organic toner and/or inorganic toner;
  • the organic toner is a kind of permanent red, scarlet, everbright red, everbright fast red, Lithol scarlet/magenta/dark red/ruby/purplish red, lake red, rubber scarlet, lightfast pink lake, cherry-red, quinacridone red, permanent pink, permanent ruby, permanent orange, permanent Jaffa orange, everbright fast yellow, benzidine yellow, permanent yellow, pigment fast rose red lake, pale purple, quinacridone violet, phthalocyanine green or peacock blue lake toner;

  • PVC polyvinyl chloride
  • CPE chlorinated polyethylene
  • AA acrylic acid
  • PU polyurethane
  • silica gel silica gel
  • all stabilizers used for the preparation of artificial leather are powder, which affects the permeability of such prior art artificial leather, therefore in a preferred embodiment of the present invention, a liquid stabilizer is used so as to further improve the transmittance of the prepared light-transparent artificial leather.

  • the support layer is not processed by a foaming technology or is merely processed by micro-foaming technology, and that the micro-foaming ratio is less than or equal to 1.5.
  • the preparation process also comprises a step of forming a light-shielding layer, such that in the step of light-shielding layer formation, the light-shielding layer is formed between the light-transparent epidermal layer and the support layer, and such that the light-shielding layer is a hollowed-out structure to form a pattern.

  • the support layer comprises virtually the same materials as the light-transparent epidermal layer, and the only difference therebetween is that there is toner incorporated in the support layer.
  • the support layer of conventional prior art artificial leather is a foaming structure. Because foaming affects the transmittance of artificial leather, in a preferred embodiment of the invention, the support layer is not processed by foaming technology or is merely processed by micro-foaming technology, and such micro-foaming ratio is less than or equal to 1.5.
  • each layer structure can be formed by a release paper coating method or a calendering method (both such methods are incorporated herein by reference).
  • the glue therein may be transparent glue or glue layer slurry made from polymer powder, or some other type of glue.
  • the preparation process comprises the following steps of:
  • the preparation method of the invention comprises the following steps of:
  • the surface treating agent comprises water-borne polyurethane (WPU) and water-based color paste. Owing to the low thickness of the surface treating agent layer, which therefore has little impact on transmittance, to save costs, a kind of toner with a regular particle size, such as a particle size of 1 ⁇ 5um, is can be added to the water-based color paste.
  • the surface treating agent layer may be processed by an embossing technology (which is incorporated herein by reference).
  • the glue layer material also forms a glue layer and is affixed to the support layer, while the other side of the glue layer is covered with a base fabric.
  • the base fabric can be a knitted fabric, non-woven fabric, three-dimensional spaced fabric or light-transparent polyurethane foam substrate.
