High-strength plastics-steel door and window profile

Abstract

The invention discloses a high-strength plastics-steel door and window profile which comprises a rectangular hollow profile body, a reinforcing frame, metal nickel layers and decorative layers. The profile body sleeves the reinforcing frame. Reinforcing ribs are arranged on the inner wall of the reinforcing frame. The reinforcing ribs are vertical to the reinforcing frame. A short plate and a long plate are arranged on both end parts of the top of the profile body respectively, wherein the short plate and the long plate are vertical to the profile body. The bottom of the profile body is provided with a buckle rib with a hook. The metal nickel layers are coated on the outer surfaces of the profile body, the short plate, the long plate and the buckle rib. The decorative layers are arranged on both sides of each metal nickel layer. The high-strength plastics-steel door and window profile provided by the invention has the advantages of simple structure, low processing cost, high production efficiency, heat resistance, abrasion resistance, corrosion resistance, long service life and high strength.

Description

technical field [0001] The invention relates to a door and window profile, in particular to a high-strength plastic steel door and window profile. Background technique [0002] General plastic-steel doors and windows use polyvinyl chloride (UPVC) resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, etc., extruded into profiles, and then made by cutting, welding or screwing. The door and window frame leaves are equipped with sealing strips, tops, hardware, etc. At the same time, in order to enhance the rigidity of the profile, reinforcing ribs need to be filled in the cavity of the profile exceeding a certain length. Resin is the main raw material, which leads to the fact that such plastic-steel doors and windows are not resistant to high temperatures, have poor fire resistance, and emit toxic gases at high temperatures. Contents of the invention [0003] The object of the present invention is to provide a high-strength plastic-stee...
