Embodiment 1

[0040] The first step: Weigh the raw materials according to the ratio of various materials in the formula. The ratio of PVC to plasticizer is 100:80-100, and then mix the raw materials evenly, including: 55 parts of PVC resin, 45 parts of plasticizer, 11 parts of solid stabilizer, 1 part of colorant; coating water-based paint on the surface of the base layer, the formula of the water-based paint includes: 85 parts of water-based polyurethane modified resin, 15 parts of auxiliary agent. The total amount of the above-mentioned water-based paint is coated on the surface of the above-mentioned base layer.

[0041] The mixing process is: confirm the weight of the slurry → convert the amount of white paste and color paste in the formula, input it into the computer → add plasticizer to the mixing tank → add stabilizer and other additives to the mixing tank → add PVC powder to the mixing tank → Stir at low speed → Stir at high speed → Vacuumize for 20 minutes → Pump back for 5 minutes...

Embodiment 2

[0048] The first step: Weigh the raw materials according to the ratio of various materials in the formula. The ratio of PVC to plasticizer is 100:80-100, and then mix the raw materials evenly, 50 parts of PVC resin, 50 parts of plasticizer, 13 parts stabilizer, 5 parts of colorants; the surface of the base layer is coated with water-based paint, and the formula of the water-based paint includes: 90 parts of water-based polyurethane modified resins, and 10 parts of auxiliary agents. The total amount of the above-mentioned water-based paint is coated on the surface of the above-mentioned base layer.

[0049] The mixing process is: confirm the weight of the slurry → convert the amount of white paste and color paste in the formula, input it into the computer → add plasticizer to the mixing tank → add stabilizer and other additives to the mixing tank → add PVC powder to the mixing tank → Stir at low speed → Stir at high speed → Vacuumize for 20 minutes → Pump back for 5 minutes → V...

Embodiment 3

[0056] The first step: Weigh the raw materials according to the ratio of various materials in the formula. The ratio of PVC to plasticizer is 100:80-100, and then mix the raw materials evenly, 70 parts of PVC resin, 30 parts of plasticizer, 18 parts stabilizer, 7 parts of colorants; the surface of the base layer is coated with water-based paint, and the formula of the water-based paint includes: 88 parts of water-based polyurethane modified resins, 12 parts of auxiliary agents. The total amount of the above-mentioned water-based paint is coated on the surface of the above-mentioned base layer.

Abstract

The invention relates to a high temperature and amine resistant PVC artificial leather, which is composed of the following components in parts by weight: 50 to 70 parts of PVC resin, 30 to 50 parts of plasticizer, and 1 to 7 parts of pigment, and aqueous paint, which comprises 85 to 90 parts of aqueous polyurethane modified resin and 10 to 15 parts of auxiliary agent; wherein the plasticizer is a low-volatile linear polymer plasticizer, the pigment comprises one or more of chromium-antimony-titanium yellow, iron red, and titanium dioxide; and the auxiliary agent comprises one or more of wetting auxiliary agent, antifoaming auxiliary agent, and thickening auxiliary agent. The PVC artificial leather also comprises 11 to 18 parts of solid stabilizing agent. The solid stabilizing agent contains perchlorate. The amine resistant performance of the perchlorate-containing solid stabilizing agent is stronger than that of organic liquid stabilizing agent, and the high temperature resistant performance of the perchlorate-containing solid stabilizing agent is better than that of epoxy liquid stabilizing agent. The prepared PVC artificial leather has excellent high temperature and amine resistant properties.

Description

technical field [0001] The invention belongs to the field of automotive interior materials, in particular to an artificial leather material, in particular to a high-temperature-resistant and amine-resistant PVC artificial leather and a preparation method thereof. Background technique [0002] In recent years, with the development of the economy, automobiles have become ordinary consumer goods. With the increase in automobile production and sales, consumers have higher and higher requirements for the quality and cost performance of automobiles. Among them, automobile interior materials also reflect the An indicator of quality and class. [0003] At present, the automotive interior materials include PVC artificial leather, PU artificial leather and so on. For automotive interior materials, it is necessary to have good performance indicators, such as high temperature resistance, amine resistance, light resistance, and at the same time, it is required to meet the requirements o...
