Embodiment 1

[0016] Embodiment 1: with reference to attached figure 1 and 2 . Polyurethane composite energy-saving window frame or sash frame profile, which includes glass fibers, and the multiple bundles of glass fibers are densely distributed to form the window frame or sash frame profile forming skeleton 1, and polyurethane resin 2 is composited with the inside and outside of the window frame or sash frame profile forming skeleton 1 And constitute a polyurethane window frame or sash frame profile, that is to say, the molding skeleton 1 of the window frame or sash frame profile is composed of multiple bundles of glass fibers, and the polyurethane resin 2 is completely composited with each glass fiber surface in the multiple bundles of glass fibers. And the glass fibers compounded with polyurethane resin 2 are bonded and solidified to form the required window frame or sash frame profile, that is, the inside and outside of the window frame or sash frame profile molding skeleton 1 refers t...

Embodiment 1-1

[0017] Example 1-1: On the basis of Example 1, 35%-40% polyurethane and 60%-75% glass fiber can be pultruded polyurethane profiles, which have better physical, mechanical and mechanical properties.

Embodiment 1-2

[0018] Example 1-2: On the basis of Example 1, 30%-35% polyurethane and 65%-70% glass fiber can be pultruded polyurethane profiles, which have good physical, mechanical and mechanical properties.

Abstract

The invention relates to an energy-saving window frame or window sash profile of a polyurethane composite material consisting of polyurethane resin and glass fibers and a forming method. The profile comprises the glass fibers; a plurality of bundles of glass fibers are densely distributed to form a window frame or window sash profile forming skeleton; and the polyurethane is compounded on the inner and outer surfaces of the window frame or window sash profile forming skeleton to form the polyurethane window frame or window sash profile. The profile has the advantages that: the profile has light weight, high strength, energy conservation, heat insulation, health, environmental friendliness, remarkable energy-saving effect, corrosion and ageing resistance, long service life, good dimensional stability, good weather resistance, good high temperature resistance, better low temperature resistance, good insulating performance, good shock absorption performance and rich colors; the polyurethane composite material has high hardness and can be used for coating various paints to prepare the profiles of various colors to adapt the application of different styles and grades; and the profile has fatigue resistance, and the polyurethane composite material has high fatigue resistance so as to ensure use safety and reliability of the material.

Description

technical field [0001] The invention relates to an energy-saving polyurethane composite material energy-saving window frame or sash frame profile and a molding method which are composed of polyurethane resin and glass fiber, and belongs to the field of composite profile manufacturing. Background technique [0002] At present, the popular architectural doors and windows on the market are mainly made of wood, aluminum alloy, plastic steel, broken bridge aluminum, wood-aluminum composite or aluminum-plastic composite materials; A new material, commonly known as "Fiber Reinforced Plastics" (English name Fiber Reinforced Plastics, FRP for short), which is made of unsaturated polyester resin and glass fiber, was introduced to process the door and window system, that is, FRP doors and windows. [0003] Unsaturated polyester resin is a kind of thermosetting resin, which can be cured into an insoluble and infusible high molecular network polymer under the action of heat or initiator,...
