Abstract
The invention relates to a PVC compact layer composition for preparing artificial leather, which is characterized by comprising the following components: 50-70 parts of PVC resin and 30-50 parts of plasticizer, wherein the plasticizer comprises a compound shown in formula (I), and n is 6-20 in the formula (I). The invention also relates to a PVC foaming layer composition for preparing artificial leather, which is characterized by comprising the following components: 50-70 parts of PVC resin, 30-50 parts of plasticizer and 1-5 parts of foaming agent, wherein the plasticizer comprises a compound shown in formula (I), and n is 6-20 in the formula (I). Compared with the traditional PVC artificial leather, the PVC artificial leather disclosed by the invention has the advantage that the VOC in the automobile is reduced.
Description
Technical Field
The invention relates to the field of automotive interior materials, in particular to polyvinyl chloride (PVC) artificial leather for automotive interior.
Background
The important role of plasticizers in high molecular weight polymers is to increase plasticity, make them easier to process, and impart flexibility to articles. At present, plasticizers are among the largest plastic aids to be produced and consumed. China has become the country with the most plasticizer output and consumption in Asian regions.
At present, plasticizers adopted by PVC artificial leather mainly comprise phthalate products such as phthalate, but as the application of phthalate is more and more extensive, people pay more and more attention to the toxicity of phthalate. Researches show that phthalate contained in PVC artificial leather is easy to migrate to the surface of the material under grease or high-temperature environment of more than 100 ℃ and causes harmful gas to volatilize. These migrating or released harmful substances have serious effects on the immune system, nervous system and reproductive system of the human body and are even carcinogenic, and children, the elderly and people with defective immune systems are more vulnerable to threats.
Due to the narrow space of the automobile and the good sealing performance of the automobile, harmful gas in the automobile is easier to exceed the standard, and the degree of harm to human bodies is larger. Therefore, the damage of the automobile interior to the human body does not vary a little. And phthalate is the plasticizer adopted by most of the current PVC automobile interior trims. Although the harmful gas in the vehicle can be reduced by the conventional method, for example: the air in the vehicle is purified, ventilated and ventilated frequently, but the traditional methods are temporary and permanent, and can not reduce the migration and emission of harmful substances radically.
Therefore, it is required to find a polyvinyl chloride artificial leather having a reduced volatile organic compound content for automotive interior.
