Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of polyolefine material, preparation method and application thereof.
Background technology
The template of using in the construction work at present generally can be divided into two kinds of metal form and nonmetal templates, common steel template in the metal form, though punching block is firm in structure, can repeatedly use repeatedly, but exist from great, corrosion stability is poor, and the difficult shortcoming of the demoulding.Wooden template in the nonmetal template because it can be according to any intercepting of building structure, thereby has been brought convenience to construction; Yet it also exists intensity low simultaneously, and the back that makes moist is yielding; Reuse the few shortcoming of number of times; And the wall leveling degree that adopts wooden model to build also is weak, and pieces together that to tear efficient open low, the both uneconomical timber resources of also wasting.In recent years, along with organic chemical industry's Development of Materials, plastic mould is owing to having the favor that receives building trade from heavy and light, anti-corrosion, water resisting advantage.But existing plastic mould is not generally promoted, and traces it to its cause, and is that the intensity of plastic mould is not high, yielding on the one hand, to having relatively high expectations of support system; Be that common injection moulding template has limitation dimensionally on the other hand, can saw and to cut out, build conveniently not as nonmetal template; In addition, general modified plastics only is applicable to the building template that is injection molded into ad hoc structure, or than great, or in copying use mechanically, broke easily, there is shortcoming in practicality.
Disclose among the Chinese patent CN1563637 that a kind of inorganic nano-particle strengthens that polyolefine material is used to extrude or laminated into type, finally formed the building template of plate construction, can need sawing to become the sheet material of all size by standard or building.Yet this kind sheet material is the solid construction that thickness reaches 10mm, than great, and carrying inconvenience in actual the use; And in the material produce process, nanoparticle is not easy to disperse, and the technology of production is not easy control.Thereby, for the lightweight that realizes the building template material, easy saw are cut out, HS, development of new is highly significant material modified.
Summary of the invention
The purpose of this invention is to provide a kind of polyolefine material, this material has in light weight, and rigid-tough balance is good and be easy to advantages such as the demoulding.
