Description

Technical Field

[0001] The invention relates to the field of building materials, in particular to a composite door and window profile. Background Art

[0002] Plastic profiles, including wood-plastic profiles, have become the main material for door and window profiles due to their good performance and cost-effectiveness. However, plastic profiles have the characteristic of creep, that is, long-term load will lead to slow deformation.

[0003] To solve this problem, people add steel linings into the cavities of plastic profiles, but adding steel linings brings new problems, namely, the thermal insulation performance of plastic profiles will be reduced. This is inappropriate at a time when energy conservation and emission reduction has become a national strategy. In addition, the steel lining is mechanically embedded into the cavities of plastic profiles at a later stage. The steel lining and plastic profiles are simply squeezed together, or fixed with screws at a certain distance, and do not form a whole, which makes the reinforcement effect of the steel lining unable to be fully exerted.

[0004] Therefore, developing a composite door and window profile is a problem that those skilled in the art need to solve urgently. Summary of the invention

[0005] In view of this, the present invention provides a composite door and window profile to solve the problems in the prior art that the plastic profile will deform and the steel lining and the plastic profile cannot form a whole.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] A composite door and window profile, comprising a plastic profile, a glass fiber reinforced plastic lining, and a lightweight thermal insulation material;

[0008] The plastic profile is the outermost frame structure of the composite door and window profile, the fiberglass lining is arranged on the inner side of the plastic profile, and the lightweight thermal insulation material is filled in the cavity surrounded by the fiberglass lining or the plastic profile.

[0009] The beneficial effects of adopting the above technical solution are: the fiberglass lining can prevent the creep of the plastic profile, making up for the defects of the traditional plastic profile, and the lightweight thermal insulation material can further improve the thermal insulation performance of the profile.

[0010] Furthermore, the composite door and window profile includes a composite profile with a buckle and a composite profile without a buckle; the composite profile with a buckle, wherein the four frames of the fiberglass lining are all provided with openings, a buckle protruding toward the inside of the cavity is provided with the opening as the lower bottom, the bottom of the buckle adjacent to the cavity is the upper bottom, and the length of the upper bottom is greater than the lower bottom;

[0011] The buckle-free composite profile has no openings on the fiberglass lining, that is, no buckles.

[0012] The beneficial effects of adopting the above technical solution are: the buckle can further improve the bonding strength between the glass fiber reinforced plastic lining and the plastic profile, thereby improving the overall strength of the present invention;

[0013] Furthermore, the fiberglass lining is a glass fiber profile bonded with resin.

[0014] The beneficial effects of adopting the above technical solution are: the material of the fiberglass lining is easy to purchase on the market, and is light and hard, has good mechanical properties and low thermal conductivity. Using it as the lining of the plastic profile can not only solve the problem of creep of the plastic profile, but also does not bring the disadvantage of reduced thermal insulation performance like traditional steel lining.

[0015] Furthermore, the lightweight thermal insulation material includes foamed polyurethane, foamed phenolic, glass wool, and rock wool.

[0016] The beneficial effects of adopting the above technical solution are: the above lightweight thermal insulation material has a good thermal insulation effect, and due to its material characteristics, it is easy to fill, thereby simplifying the manufacturing process of the present invention.

[0017] Furthermore, the composite door and window profile is manufactured by a co-extrusion process, and the specific steps are as follows:

[0018] (1) purchasing or manufacturing the fiberglass lining according to the designed cross-sectional shape;

[0019] (2) placing the fiberglass liner at a set position of an extrusion die on a co-extrusion device;

[0020] (3) turning on the co-extrusion equipment, allowing the glass fiber reinforced plastic lining to be wrapped by the plastic profile extruded by the co-extrusion equipment, and being extruded together, and cut off according to a set length;

[0021] (4) Fill the cavity of the profile with lightweight insulation material.

[0022] The beneficial effects of the above technical solution are: through the co-extrusion process, the FRP lining and the surrounding plastic profiles can be bonded to form a whole, which can give full play to the reinforcing effect of the FRP. Since the plastic profile and the FRP lining are both poor conductors of heat, the cavity of the FRP lining is filled with insulation material, and its insulation performance is greatly improved.

[0023] Furthermore, in order to increase the aesthetics of the present invention, the ornamental surface of the composite door and window profile can be flexibly decorated with various measures, such as lamination, metal wrapping, wood veneer, painting, etc.

[0024] In summary, the present invention utilizes the good mechanical properties of the FRP lining to perfectly solve the creep problem of the plastic profile, ensures that the present invention will not deform, and compensates for the poor thermal insulation performance of the traditional steel lining by filling with thermal insulation materials. Moreover, the present invention is made through a co-extrusion process, which can make the plastic profile and the FRP lining bonded to truly form a whole. At the same time, the raw materials of the present invention are simple and easy to obtain, the structure is also very simple, the manufacturing process is not complicated, the manufacturing cost is low, the audience is wide, and the overall weight is light, easy to carry, suitable for promotion and use as door and window profiles.
