Abstract

The invention discloses the formula of a PVC automobile interior material, which is prepared from 50 to 60 weight parts of poly(vinylchloride) resin, 40 to 50 weight parts of plasticizer and 1.5 to 2.0 weight parts of stabilizer, wherein the K value of the poly(vinylchloride) resin is 70 to 80, the viscosity of the poly(vinylchloride) resin is 1,500 to 4,500cps, the vinyl chloride monomer (VCM) content is less than 10 ppm, the residue on sieve is less than 1, the foreign particle number is less than 10, and the whiteness is more than 85. The poly(vinylchloride) resin is white powder, the plasticizer is an ether plasticizer and the stabilizer is organic tin stabilizer. The formula of the PVC can effectively solve the paper sticking problem, and the PVC has high light resistance and wire resistance and can meet the requirements of main machine manufacturers.

Description

technical field [0001] The invention relates to a PVC formula, in particular to a PVC formula for automotive interior materials. Background technique [0002] With the rapid development of the automobile industry, consumers not only pay attention to the beauty of the exterior shape of the car when buying a car, but more and more consumers value the beauty of the interior material of the car. The interior material of the car has become an important factor affecting the quality and An important factor of grade, the current car interior materials PVC artificial leather, PU artificial leather and so on. The PVC artificial leather material used for automotive interiors requires PVC to have good various performance indicators to meet the requirements of various host manufacturers, such as light resistance and good wear resistance, but at present, PVC and release paper may also appear when molding PVC Difficult to separate phenomenon. [0003] Therefore, it is necessary to provid...
