Abstract

A technology for making the sealing strip of door or window includes such steps as mixing 12 raw materials including PVC, lead stearate, barium stearate, paraffin wax, titanium white powder, AC, etc, pulverizing, plasticizing, granulating, extruding out for shaping, and cooling in water. Its advantages are high resistance to cold, fire, and ageing, high mechanical strength, toughness and elasticity, and high sealing effect.

Description

technical field [0001] The invention relates to a method for manufacturing a door and window sealing strip, which is used for sealing aluminum alloy doors and windows, plastic steel doors and windows, automobile doors and windows, etc., and belongs to the technical field of building materials. Background technique [0002] At present, the sealing strips used for sealing aluminum alloy doors and windows, plastic steel doors and windows, and automobile doors and windows are usually made of PVC and filler (stone powder) as the main raw materials through mixing, granulation, and extrusion molding. The sealing strip produced by the above-mentioned formula process is easy to break, prematurely aging, and has a short service life; the sound insulation effect is poor, and it cannot meet the sealing requirements of water vapor and performance, which will easily cause adverse consequences for thousands of users in the construction industry. Invention content: [0003] The purpose of...
