Abstract
The utility model relates to a polyurethane reinforced plastic profile, which relates to the building material field. In order to improve the applying strength, the technology of steel lining in the cavities is adopted in the prior plastic profile; however, the plastic profile exists the problems that the processing is complex, the weight is great, and the cost is high, therefore the lined polyurethane in the inner cavities as the inner layer is provided in the plastic profile of the utility model, hard polyester polyurethane foam plastic or hard polyether polyurethane foam plastic is used as the inner layer, the thickness of the internal layer is 3 to 6 times larger than the thickness of the outer layer, and the polyurethane reinforced plastic profile has the advantages that the processing is convenient, the internal layer and the outer layer can be extruded and molded at a time, the weight is light, the installation is convenient, and the cost is low.
Description
Technical field
The utility model relates to building materials field, especially plastic material.
Background technology
Along with expanding economy, timber is as important constructional materials, and requirement sharply increases, caused the excessive exploitation of timber resources, and then destroyed human ecological environment of depending on for existence, need spend decades, go up the century-old time and could recover, so the consumption that reduces timber is the task of top priority.Various types of in addition plastic materials have obtained development at full speed, they have characteristics such as output is big, price is low, easy to process, in light weight, some plastic material can be used as the alternative of timber, their physical property, chemical property, processing characteristics all satisfy the requirement of building aspect to some extent, and it is feasible, correct therefore coming the direction of replacing wood with plastics.At present existing many building units replace with plastics, but must finish timber and plastics are two kinds of dissimilar materials, and different characteristics and difference are arranged, lower as the intensity of plastics, the hot strength 34-62Mpa of polyvinyl chloride, bending strength 68-123Mpa is in order to improve working strength, lining steel profile in plastic material, this method exists processed complex, weight is big, the problem that cost is high for this reason, must be sought more method.
Summary of the invention
The plastic material that the purpose of this utility model strengthens for the polyurethane that provides a kind of simple in structure, easy to process, in light weight, cost is low.
The technical scheme that realizes the foregoing invention purpose is as follows:
The plastic material that polyurethane strengthens has double-layer structure, and skin is a plastic material, is lined with one deck polyurethane as internal layer in the inner chamber of section bar, the shape of internal layer and outer inner chamber coupling, and thickness is 3-6 times of outer layer thickness.
The polyurethane internal layer is hard polyester type polyurethane foamed plastics or hard polyetber polyurethane foam.
Add and utilize screw extruder and shaper extrusion plastic section bar skin man-hour, by polyurethane foam equipment polyurethane foam is also passed through internal layer shaper injected plastic section bar inner chamber as internal layer again.
Hard polyaminoester has premium properties such as specific strength is big, light weight, thermal insulation, sound insulation, and can be processed into different shapes man-hour as requested, good processability adding.Therefore the hard polyaminoester lining can be improved the intensity of plastic material at the plastic material inwall.The ratio of ectonexine thickness should be according to the rigidity of material, the size of structure body and the size of cavity, the size and the weight decision of member own of supporting force.
The present invention has following beneficial effect
1, having changed prior art needs special operation that the technology that strengthens steel lining is installed, and the utility model can use an inside and outside two-layer extrusion molding.
2, in light weight, easy for installation, be applicable to frame section, fan-shaped material and middle stile section bar.
3, cost low, be convenient to promote.
Description of drawings
The plastic material structural representation that Fig. 1 strengthens for the utility model polyurethane
The specific embodiment
Now the technical solution of the utility model is described further by the following example.
Fig. 1 has shown that the skin 1 of plastic material is a polyvinyl chloride layer, and internal layer 2 is a hard polyester type polyurethane foamed plastics, and two lateral surfaces are close to outer medial surface about internal layer, this part is a frame section, stressed medium with supporting force, internal cavities is bigger, so layer thickness is outer field 4 times in selected.
Claims (2)
1, the plastic material that strengthens of polyurethane is characterized by and has double-layer structure, and skin be plastic material, is lined with one deck polyurethane as internal layer in the inner chamber of section bar, and the shape of internal layer and outer inner chamber mate, and thickness is 3-6 times of outer layer thickness.
2, the plastic material of polyurethane enhancing according to claim 1, it is characterized by the polyurethane internal layer is hard polyester type polyurethane foamed plastics or hard polyetber polyurethane foam.
