Abstract
The invention provides a mesh reinforcing rib polyurethane board for external thermal insulation of an outer-wall, wherein a layer of bidirectional mesh reinforcing rib made of a glass fiber mesh, a metal steel wire mesh or a chemical fiber mesh is clamped in the surface layer on the surface of the polyurethane board so as to improve the tensile strength and the breaking strength of the polyurethane board. The protective layer of the polyurethane board outside the reinforcing rib is isolated from the environment outside the board, so the corrosion resistance and durability of the reinforcing rib can be improved. The best pore diameter distance of the glass fiber or chemical fiber mesh reinforcing ribs is 7-15*7-15mm, and the best thickness of the reinforcing rib protective layer is between 8 and 12mm; and the best pore diameter distance of the metal steel wire mesh reinforcing ribs is 10-30*10-30mm, and the best thickness of the reinforcing rib protective layer is between 8 and 30mm. The mesh reinforcing rib polyurethane board is suitable for a polyurethane board external thermal insulation wall anchored by a mechanical fixing device, can remarkably improve the stability and the use safety of the external thermal insulating layer, and is particularly suitable for the external thermal insulation energy-saving improving project for the conventional building wall.
Description
Affiliated technical field
The present invention relates to accompany in a kind of top layer the polyurethane sheet of two-way grid reinforcing rib, be particularly useful for the external heat insulating wall of mechanical fastening system anchoring polyurethane sheet.
Background technology
At present, existing polyurethane sheet sheet material is by molding machine die compression set type after foaming, be characterized in that density and coefficient of thermal conductivity are more satisfactory, but tensile strength and rupture strength are lower, easily produce cracking, distortion, shrink, when being used for mechanical anchor heat-insulation plate for external body of wall, exist by the heat insulating polyurethane plate of anchored enbrittle, the problem and the shortcoming of easy fracture, therefore need to improve.
Summary of the invention
In order to overcome the defective of the existing polyurethane sheet insulation layer of mechanical fastening system anchoring less stable, the invention provides a kind of grid reinforcing rib polyurethane sheet, this grid reinforcing rib polyurethane sheet can improve the tensile strength and the rupture strength of plate, thereby strengthens the mechanical property and the resistance to overturning of polyurethane sheet outer heat preservation system.
The technical solution adopted for the present invention to solve the technical problems is: in the plate face top layer of heat insulating polyurethane plate; the two-way grid reinforcing rib of one deck is set; reinforcing rib is fiberglass gridding reinforcing rib, metal grill reinforcing rib or chemical fibre grid reinforcing rib; it is characterized in that: the external surface of grid reinforcing rib is with one deck polyurethane sheet topping; make isolation such as the thin floated coat mortar of the outer environment of grid reinforcing rib and plate face, improve anticorrosive and durability.As required, grid reinforcing rib can be in the two-sided setting of plate, also can be in the single face setting of plate.
Above-mentioned fiberglass gridding reinforcing rib is to be formed by glass fiber warp and parallel right-angled intersection woollen yarn knitting, and the grid aperture spacing of reinforcing rib is 5～25 * 5～25mm, and optimal spacing is 7～15 * 7～15mm; The protective layer thickness of grid reinforcing rib is 5～25mm from the outer peripheral distance of plate face promptly, and optimum thickness is 8～12mm.
Above-mentioned metal grill reinforcing rib is to be formed by connecting by vertical steel wire and transverse steel wire right-angled intersection electric welding, and the grid aperture spacing of reinforcing rib is 5～60 * 5～60mm, and optimal spacing is 10～30 * 10～30mm; Reinforcing rib is hot-dip galvanizing steel wire, cold-drawn low-carbon wire, stainless steel wire or alloy-steel wire; Steel wire diameter is 0.5～4.0mm, and optimum diameter is 0.9～2.5mm; The protective layer thickness of reinforcing rib is 5～50mm, and optimum thickness is 8～30mm.
Above-mentioned chemical fibre grid reinforcing rib is to be formed by chemical fibre warp and parallel right-angled intersection woollen yarn knitting, and chemical fibre is polyester fiber, Fypro, polyacrylonitrile fibre, vinal or polyolefine fiber; The grid aperture spacing of reinforcing rib is 5～25 * 5～25mm, and optimal spacing is 7～15 * 7～15mm; The protective layer thickness of reinforcing rib is 5～25mm, and optimum thickness is 8～12mm.
The present invention can use grid reinforcing rib and polyurethane sheet one step completed method in mold pressing, forming process, and the grid reinforcing rib folder is attached in the top layer of polyurethane sheet, guarantees the globality and the seal of grid reinforcing rib medial and lateral polyurethane plate body.
The invention has the beneficial effects as follows: compare with existing polyurethane sheet, the grid reinforcing rib polyurethane sheet has tensile strength and the obvious advantage that improves of rupture strength.Be applicable to the external heat insulating wall of mechanical fastening system anchoring polyurethane sheet, can solve the shortcoming of the intrinsic fragility of polyurethane sheet, easy fracture.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing
Fig. 1 is an organigram of the present invention.
Fig. 2 is the longitudinal sectional drawing of Fig. 1.
Among the figure: 1. polyurethane central layer, 2. grid reinforcing rib, 3. the polyurethane sheet topping of reinforcing rib
The specific embodiment
In Fig. 1, Fig. 2, grid reinforcing rib polyurethane sheet of the present invention is made up of the polyurethane sheet topping 3 of polyurethane central layer 1, grid reinforcing rib 2 and reinforcing rib from inside to outside successively.Grid reinforcing rib 2 is to be formed by glass fiber or science fabric warp and parallel right-angled intersection woollen yarn knitting, perhaps is formed by connecting by vertical steel wire and transverse steel wire right-angled intersection electric welding.The polyurethane sheet topping 3 and the 1 synchronous processing moulding of polyurethane central layer of reinforcing rib are combined into a whole sheet material, and grid reinforcing rib 2 and the external environment conditions such as thin floated coat on the plate face are isolated, and prevent that reinforcing rib from being alkalized, corroding.
