Abstract

The invention discloses a flame-retardant PVC (polyvinyl chloride) profile for doors and windows and a production method thereof. The flame-retardant PVC profile comprises, by weight, 55-60 parts of PVC waste, 13-17 parts of wood flour, 15-18 parts of light calcium carbonate, 0.38-0.54 part of titanium dioxide, 6.4-8.3 parts of CPE impact modifier, 0.72-0.96 part of organic tin stabilizer, 0.35-0.42 part of metallic soap stabilizer, 0.9-1.2 parts of fatty alcohol lubricant and 1.3-2.5 parts of flame retardant. The PVC profile is good in flame retardant effect, can reach 2.1mmV1 level in vertical flammability and good in heat resistance. Meanwhile, the PVC profile has excellent impact resistance, bending deformation resistance and tensile impact resistance.

Description

technical field [0001] The invention relates to the field of decorative materials, in particular to a flame-retardant PVC profile for doors and windows and a preparation method thereof. Background technique [0002] The English abbreviation of polyvinyl chloride is PVC, which is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator, and is a homopolymer of vinyl chloride. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. PVC is a white powder with an amorphous structure and a small degree of branching. PVC is the most widely used general-purpose plastic in the world. It is widely used in building materials, industrial products, daily necessities, door and window leather, door and window bricks, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc. are widely applied. [0003] PVC profiles are industrial and domes...
