Cold-resistant and antifreeze composite material for plastic windows and doors

Abstract

The invention discloses a cold-resistant and antifreeze composite material for plastic windows and doors. The composite material is prepared from the following ingredients in parts by mass: 50-80 parts of PVC, 35-50 parts of ABS, 15-20 parts of talcum powder, 30-50 parts of calcium carbonate, 15-20 parts of wood flour, 10-15 parts of polyamide fibers, 0.5-1 part of foamer, 1-2 parts of foaming regulator, 4-8 parts of polyethylene wax, 2-5 parts of toughener, 2-3 parts of calcium stearate, 2-6 parts of couplant, 3-6 parts of flame retardant, 1-2 parts of anti-aging agent, 1-2 parts of ACR modifier and 1-2 parts of paraffin. According to the cold-resistant and antifreeze composite material, through jointly using the PVC and the ABS and comprehensively using a stabilizer, the flame retardant,the polyamide fibers and the like, products with good strength and toughness are obtained, have excellent heat resistance, wear resistance and flame retardance and are low in expansion ratio and lowin thermal shrinkage, thereby being ideal plastic-wood floorboard articles.

Description

technical field [0001] The invention belongs to the field of composite material manufacturing, in particular to a composite material for cold-resistant and frost-resistant plastic doors and windows. Background technique [0002] Plastic doors and windows are doors and windows made of polyvinyl chloride (PVC) resin as the main raw material and extruded molding materials. According to the material, they can be divided into PVC plastic doors and windows and glass fiber reinforced plastic doors and windows. Plastic doors and windows have good properties such as wind resistance, waterproof, and heat preservation, as well as advantages such as saving profiles and recyclable materials, so they are more and more widely used. [0003] In the northern region, the temperature in winter is low, and the existing polyvinyl chloride plastics usually have the disadvantages of poor low temperature resistance and low frost resistance and impact strength.
