Problems solved by technology

Although traditional methods can be used to reduce harmful gases in the car, such as: purifying the air in the car, ventilating frequently, etc., these traditional methods treat the symptoms but not the root cause, and cannot reduce the migration and distribution of harmful substances from the root.

Abstract

The present invention relates to a PVC compact layer composition for preparing artificial leather. The PVC compact layer composition is characterized by comprising the following components: 50-70 parts by weight of PVC resin and 30-50 parts by weight of a plasticizer, wherein the plasticizer comprises a compound as shown in a formula (I), and in the formula (I), n is equal to 6-20. The present invention also relates to a PVC foaming layer composition for preparing the artificial leather. The PVC foaming layer composition is characterized by comprising the following components: 50-70 parts by weight of the PVC resin, 30-50 parts by weight of the plasticizer and 1-5 parts by weight of a foaming agent, wherein the plasticizer comprises the compound as shown in the formula (I), and in the formula (I), n is equal to 6-20. The PVC artificial leather reduces VOC in a vehicle compared with conventional PVC artificial leather.

Description

technical field [0001] The invention relates to the field of automobile interior materials, in particular to a polyvinyl chloride (also called PVC) artificial leather used for automobile interiors. Background technique [0002] The important role of plasticizers in high molecular polymers is to increase plasticity, make them easy to process, and give softness to products. At present, plasticizer is one of the plastic additives with the largest output and consumption. my country has become the country with the largest production and consumption of plasticizers in Asia. [0003] At present, the plasticizers used in PVC artificial leather are mainly ortho-phenyl ester products such as phthalates, but as phthalates are more and more widely used, people are becoming more and more toxic to them. more attention. Studies have shown that the phthalates contained in PVC artificial leather can easily migrate to the surface of the material and cause harmful gases to volatilize in oil...
