Abstract

The invention relates to a PVC (polyvinyl chloride) composite rubber strip for UPVC (unplasticized polyvinyl chloride) profile co-extrusion and a method for preparing the PVC composite rubber strip, and belongs to the technical field of polyvinyl chloride soft products. The technical scheme includes that a rubber material A and rubber material B are produced by the aid of two types of plasticizers, are coextruded in a rear co-extrusion die by the aid of two co-extruders and then are adhered on PVC profiles after being extruded, and the rubber material A comprises, by weight, 35-40 parts of PVC, 10-20 parts of DBP (dibutyl phthalate), 10-20 parts of chlorinated paraffin, 1.5-2.5 parts of stabilizers and 15-30 parts of inorganic fillers; the rubber material B comprises, by weight, 35-40 parts of PVC, 20-25 parts of DOP (dioctyl-phthalate), 5-10 parts of DOA (dioctyl adipate), 10-20 parts of polyester plasticizers, 1.5-2.5 parts of stabilizers and 5-20 parts of inorganic fillers, and the rubber material A and the rubber material B further can comprise 0.5-1 part of stearic acid and 1-2 parts of toner.

Description

technical field [0001] The invention relates to a PVC composite rubber strip for co-extrusion of UPVC profiles and a preparation method thereof, belonging to the technical field of polyvinyl chloride soft products. Background technique [0002] With its excellent thermal insulation, sound insulation, air tightness, water tightness, corrosion resistance and other advantages, plastic steel doors and windows have replaced steel and wooden doors and windows and have been widely used. Now with the development of plastic-steel doors and windows and the continuous improvement of people's needs, plastic-steel profiles are directly co-extruded with PVC strips on the profiles in the production process to achieve better air-tightness and water-tightness of the windows, and during the installation process Save time and labor. [0003] However, the PVC co-extruded rubber strips applied to plastic-steel profiles still have great defects, which limit the application of PVC co-extruded rub...
