Abstract

The invention discloses a self-bonding type thermoplastic macromolecular sealing strip for doors and windows and its preparation method. The sealing strip is prepared by evenly blending and stirring ethylene-octylene copolymer, polypropylene, EPDM, linear low density polyethylene, styrene-isoprene copolymer, compounding flame retardant, filling system, naphthenic oil, coupling agent and anti-agingsystem in a high-speed kneading machine; adding to a dual-screw extruder to react, blend and extrude; cooling and shaping the sealing strip extruded by an opening die through a water tank from; air-drying through an air flue and then compounding with pressure-sensitive adhesive; blending and extruding the ethylene-octylene copolymer, polyisobutene, butyl rubber, nature rubber, oil resin, naphthenic oil in the dual-screw extruder by the pressure-sensitive adhesive self-gluing layer; then synchronously compounding the pressure-sensitive adhesive with the sealing strip. The self-bonding type thermoplastic macromolecular sealing strip has the beneficial effects of high flexibility, anti-aging, and recyclable.

Description

technical field [0001] The invention belongs to the technical field of material science and relates to a door and window sealing strip made of self-adhesive thermoplastic polymer material and a preparation method thereof. Background technique [0002] In recent years, the rapid development of my country's chemical industry has enabled new chemical materials and new varieties to quickly follow up with the international development level, driving the development of new materials in industries such as automobiles, construction, wire and cable, and consumption. The market demand for body products is also growing. At present, thermoplastic elastomer materials have been listed as a supporting project of the national "High-tech Research and Development Program" (863 Program), and the market prospect is getting wider and wider. [0003] At present, the sealing strips used in domestic outdoor building doors and windows are mainly based on polyvinyl chloride (PVC), thermoplastic elast...
