Abstract

The invention relates to a polyurethane composite profile and a forming method for the same, wherein the polyurethane composite profile is made of polyurethane resins and a plurality of glass fibers. The glass fibers are densely covered to form a profile framework, and the polyurethane resins are composited with the inner surface and the outer surface of the profile framework to form the polyurethane composite profile. The polyurethane composite profile has the advantages that firstly, the profile is light in weight and high in strength; secondly, the profile is energy-saving and heat-insulation; thirdly, the profile is healthful, green, environment-friendly and remarkable in energy-saving effect; fourthly, the profile is corrosion-resistant, aging-resistant and long in service life; fifthly, the profile is fine in dimensional stability; sixthly, the profile is fine in weather resistance, fine in high-temperature resistance and better in low-temperature resistance; seventhly, the profile is fine in insulating property; eighthly, the profile is fine in vibration reducing performance; ninthly, the profile is colorful, and polyurethane composite is high in hardness and can be coated with various coatings to manufacture profiles in various colors, so that the profiles adapt to different styles and grades; and tenthly, the polyurethane composite is extremely high in fatigue resistance so that safety and reliability in use of the polyurethane composite are ensured.

Description

technical field [0001] The invention relates to a high-strength, low-specific-gravity, insulating, microwave-permeable, corrosion-resistant and heat-insulating polyurethane composite profile and a molding method, which belong to the field of composite material profile manufacture and application. Background technique [0002] At present, angle steel, I-shaped steel, channel steel, square steel, H-shaped steel, etc. sold on the market are all made of metal materials. Its shortcomings: one is the specific gravity, the specific gravity; the other is poor heat insulation performance; the third is poor corrosion resistance and easy to rust. Contents of the invention [0003] Design purpose: To avoid the deficiencies in the background technology, to design a polyurethane composite profile and molding method with high strength, low specific gravity, insulation, microwave permeability, corrosion resistance and good heat insulation effect. [0004] Design scheme: In order to achie...
