Abstract

The invention discloses a novel PVC (polyvinyl chloride) profile which comprises the following components in parts by weight: 55-65 parts of PVC waste, 12-15 parts of wood dust, 13-15 parts of light calcium carbonate, 0.72-0.84 part of titanium white, 2.5-3.2 parts of EVA (ethylene-vinyl acetate) impact modifier, 1.8-2.3 parts of MBS (methyl methacrylate-butadiene-styrene) impact modifier, 0.84-0.96 part of organic tin stabilizer, 0.48-0.51 part of epoxy compound stabilizer, 0.63-0.77 part of aliphatic acid amine and 1.5-2.4 parts of coupling agent. The PVC profile has the advantages of smooth surface, regular edge, no cracks, pores, adhesion, bubbles or scars, and high glossiness (up to 56.53Gu). The PVC profile has excellent heat-insulating property, ending deformation resistance, tensile impact resistance and solderability.

Description

technical field [0001] The invention relates to the field of decorative materials, in particular to a novel PVC profile 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 domestic PVC products that are extrud...
