Embodiment 1

[0015] Embodiment 1: with reference to attached figure 1 with 2 . Polyurethane composite material energy-saving door frame or door frame with reinforcing rib profile, which includes glass fiber, the multi-bundle glass fiber is densely distributed to form the frame 1 of the frame of the door and window, and the rib profile forming skeleton 1, polyurethane resin 2 and the frame and fan of the door and window are reinforced The inner and outer surfaces of the rib profile molding skeleton 1 are composited to form a polyurethane rib profile. The glass fibers that are completely compounded and compounded with polyurethane resin 2 are bonded and cured to form the required reinforcement profiles, that is, the frames and fans of the doors and windows are formed with reinforcement profiles. The inner and outer surfaces refer to polyurethane reinforcement profiles. face of each fiberglass in the The thickness and width of the polyurethane reinforcing rib profile are the thickness and ...

Embodiment 1-1

[0016] 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

[0017] 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 a reinforcing rib section for a polyurethane composite material energy-saving door frame or door sash frame or window frame or window sash frame, which is made from polyurethane resin and glass fiber, and a molding method. The reinforcing rib section comprises glass fibers, wherein a reinforcing rib section molding framework for a door frame / sash or a window frame / sash consists of a plurality of bundles of densely covered glass fibers; and polyurethane resin is compounded with the inner and outer surfaces of the reinforcing rib section molding framework for the door frame / sash or the window frame / sash. The reinforcing rib section has the advantages of light weight, high intensity, energy conservation, heat preservation, heat insulation, health, environmental friendliness, remarkable energy-saving effect, corrosion resistance, ageing resistance, long service life, high size stability, high weather resistance, high high-temperature resistance, higher low-temperature resistance, good insulating property, high damping performance and rich color; a polyurethane composite material has high hardness; and the reinforcing rib section can be painted with various paints to obtain sections of various colors so as to adapt to different styles and grades.

Description

technical field [0001] The invention relates to an energy-saving polyurethane composite material energy-saving door, fan frame or window and window frame made of polyurethane resin and glass fiber and a molding method thereof, belonging 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,...
