Abstract

The invention relates to a formula of color polyvinyl chloride (PVC) sections and a preparation method thereof. A main material formula comprises PVC resin, light calcium carbonate, a rare earth type heat stabilizer, a processing aid, an anti-impact toughener, a stearic acid internal lubricant, a paraffin external lubricant, a titanium dioxide light stabilizer, an aluminate coupling agent, Pigment Hansa Yellow and waste and old PVC reworked materials; an adjuvant material formula comprises suspension loose type PVC resin, light calcium carbonate, a rare earth type heat stabilizer, a processing aid, an anti-impact toughener, a titanium dioxide light stabilizer, Pigment Brilliant Red, Pigment (Carbon Black) and waste and old PVC reworked materials. Main materials and adjuvant materials are powdered and pelletized, then the particles of the main materials and the adjuvant materials are proportionally mixed according to the processing requirement of color sections, and the mixture is put into an extruding machine and then extruded. The color polyvinyl chloride (PVC) section has the advantages of simple formula and low cost, and is favorable for environmental protection; compared with aluminum sections, the finished product performance of the color polyvinyl chloride (PVC) section has the characteristics of long service life, corrosion resistance, pest resistance, easy processing, easy reclamation and the like.

Description

technical field [0001] The invention relates to a plastic formula and technology, in particular to a color polyvinyl chloride (PVC) profile formula and a preparation method thereof. Background technique [0002] In the 1980s, my country introduced two kinds of polyvinyl chloride (PVC) door and window production technology and equipment from Europe and the United States, and the production scale continued to expand. There are about 2,100 PVC door and window production lines with a production capacity of about 1 million tons. By 2005, the market share of PVC doors and windows in the national building doors and windows market will reach more than 25%, of which the market share in heating areas will reach more than 50%, and the market share in other regions and buildings that implement building energy-saving design standards will not be lower than 35%. The actual output is 800,000-900,000 tons; by 2010, PVC doors and windows will occupy more than 30% of the national building doo...
