Problems solved by technology
[0003] General PVC plastics have problems such as poor resistance to light oxidation and light aging, poor toughening effect, and poor flame retardant effect (poor light and thermal stability), so commonly used passenger car air duct panels use PVC / PE wax with low emission. brewed
However, the finished product of this air duct plate is bulky, and can only be produced by injection molding, and cannot be produced by extrusion
Moreover, the low-foaming air duct plate has low strength and is easily damaged, and there are great difficulties in secondary processing

The invention discloses a PVC passenger car air duct board produced through extrusion molding. The PVC passenger car air duct board is prepared from the following raw materials in parts by weight: 90-110 parts of PVC resin, 55-65 parts of calcium carbonate powder, 8-10 parts of an anti-impact aid, 3-4 parts of a plasticizing compound anti-impact agent, 0.5-0.7 part of an outer lubricant, 0.7-0.9 part of an inner lubricant, 0.8-1.2 parts of a smoke-abatement flame retardant, 6-9 parts of a compound stabilizer, 0.8-1.2 parts of cold-proof oil and 1.5-2.5 parts of titanium dioxide.
Description
technical field [0001] The invention relates to a PVC passenger car air channel plate. Background technique [0002] Passenger car air duct panels need to have the characteristics of high tensile strength, good impact resistance, high softening point, low combustion performance, good high and low temperature resistance, and high bending strength. Therefore, the requirements for the selection of processing aids and formulations are relatively strict. [0003] General PVC plastics have problems such as poor resistance to light oxidation and light aging, poor toughening effect, and poor flame retardant effect (poor light and thermal stability), so commonly used passenger car air duct panels use PVC / PE wax with low emission. bubble made. However, the finished product of this air duct plate is bulky, and can only be formed by injection molding, and cannot be produced by extrusion molding. Moreover, the low-foaming air channel plate has low strength and is easily damaged, and th...
