Preparation method for energy-saving door and window

Abstract

The present invention discloses a preparation method for an energy-saving door and an energy-saving window. The method is characterized in that: long glass fiber is adopted as a reinforced material; an unsaturated polyester resin is adopted as a matrix material; a pulltrusion process is adopted to produce an open-web profile; a cutting process is adopted to prepare a door frame and a window frame; wool tops, rubber strips and hardware parts are combined with the door frame and the window frame to prepare the finished door and the finished window. According to the present invention, the long glass fiber is adopted as the reinforced material, the unsaturated polyester resin is adopted as the matrix material, and the pulltrusion process is adopted to produce the open-web profile, ie., the long glass fiber is subjected to a surface vibrating and milling treatment, and is pretreated by a coupling agent, then the treated long glass fiber is subjected to blending and extruding with the polyester resin to obtain the open-web profile. The prepared energy-saving door and the prepared energy-saving window by the method of the present invention have characteristics of no expansion under direct sunlight radiation, no shrinkage in cold weather, lightweight, high strength, no requirements of metal reinforcement, aging resistance and long service life, provide more excellent comprehensive performances than other doors and windows, and provide excellent energy-saving effects.

Description

technical field [0001] The invention relates to the technical field of energy-saving doors and windows, in particular to a manufacturing method of energy-saving doors and windows. Background technique [0002] Our country is a developing country with a lot of people. It wastes a lot of energy every year because the windows are not energy-saving. In my country, building energy consumption accounts for more than 1 / 4 of the total energy consumption; building energy consumption accounts for more than 1 / 2 of building energy consumption; indoor heating and air conditioning energy consumption account for more than 1 / 5 of building energy consumption; From the perspective of building energy loss, 70% of energy loss is lost through doors and windows. According to estimates by relevant experts, if 40% of non-energy-saving windows in my country are transformed into energy-saving windows, my country can save 156 million tons of coal (equivalent to RMB 24.96 billion), and at the same time...
