Description
Technical field
The utility model belongs to heat preservation plate material technical field, is specifically related to a kind of XPS extruded sheet.
Background technology
XPS (extruded polystyrene) extruded sheet is exactly extrusion moulding type polystyrene heat insulating board.It is with polystyrene resin be raw material add other supplementary material with poly-containing thing, by heating mixing injecting catalyst simultaneously, then extrusion molding extrusion molding and the rigid foam plate that manufactures.Its formal name used at school is extrusion molding polystyrene polyfoam for heat insulation (being called for short XPS), XPS extruded sheet has perfect closed honeycomb structure, and this structure allows XPS extruded sheet have extremely low water imbibition (absorbing water hardly), low thermal conductivity coefficient, high pressure resistance, ageing resistance (normally using almost without degradation and decomposition phenomenon).
XPS extruded sheet has the following advantages: 1, excellent heat insulation property.XPS extruded sheet has high thermal resistance, low linear, feature that expansion ratio is low, and the rate of closed hole of its structure reaches more than 99%, forms vacuum layer, avoid air to flow to dispel the heat, guarantee the lasting and stable of its heat-insulating property, relative to the rate of closed hole of polyurathamc 80%, leading superiority is self-evident.Facts have proved the XPS plastic extrusion heated board that 20mm is thick, its heat insulation effect is equivalent to the thick expanded polystyrene (EPS) of 50mm, 120mm solid cement perlite.Therefore this material is the choosing of the best of current building heat preservation.2, remarkable High-strength compression resistant.Due to the special construction of XPS plate, its compressive strength is high, impact resistance is extremely strong, 150 ~ more than 700Kpa is reached according to the different model of XPS and its compressive strength of thickness, each systematically area load can be born, be widely used in the fields such as geothermal engineering, speedway, airfield runway, square ground, large cold storage and upholstery insulation.3, hydrophobic, the moisture resistance of high-quality.Water absorption rate is the important parameter weighing heat insulating material.After heat insulating material water suction, heat-insulating property declines thereupon, and at low temperatures, the water electrode of suction easily freezes, and destroys the structure of heat insulating material, thus the resistance to compression of sheet material and heat-insulating property are declined.Because polystyrene molecular structure itself does not absorb water, sheet material molecular structure stabilized, gapless, solves the problems such as other material leaks, permeates, frosting, condensation.4, quality is light, easy to use.The complete closed pore formula foaming chemical structure physical arrangement cellular with it of XPS plate, makes it have the characteristic of lightweight, high strength, is convenient to cutting, transport, and not cracky, easy for installation.5, stability, anti-corrosive properties are good.XPS plate is in using for a long time, not aging, do not decompose, do not produce hazardous substances, its chemical property is extremely stable, can not cause degraded, make its hydraulic performance decline because of water suction and corrosion etc., still can keep its superior performance in high temperature environments, according to interrelated data introduction, present domestic large factory produces XPS plastic extrusion heated board application life at about 60 years, still can keep excellent performance, and can not occur to decompose or go mouldy, there is no the volatilization of noxious material.6, product environmental protection and energy saving.XPS plate environmental-protecting performance depends primarily on blowing agent, and current most domestic manufacturer uses CO
2as catalyzer, but part producer uses freon always, has detected stable chemical performance through national departments concerned, and non-volatile hazardous substances is harmless, and raw materials for production adopt ep-type material, do not produce any industrial pollution.
Owing to having above remarkable advantage, XPS extruded sheet is widely used in the aspects such as building roofing insulation, steel structural roof, building masonry wall insulation, constructure ground moisturizing, square ground, ground frost heave controlling, ventilating duct of central air conditioner.But common extruded sheet epidermis is light face, its epidermis and bonding adhesive and plastering mortar can cementability very poor.Be badly in need of a kind of and that plastering mortar adhesion strength is high XPS extruded sheet.
Utility model content
One of the purpose of this utility model is the problem for solving XPS extruded sheet and mortar bonding difference, provides a kind of surface pressure fancy groove XPS extruded sheet.
The invention provides a kind of XPS extruded sheet, comprise plate body, the upper and lower surface of described plate body is fluted.
Further, described groove is rectangular channel.
Further, described groove runs through plate face, is parallel to each other.
Further, described recess width is 2-3mm, and the degree of depth is 3-5mm, and flute pitch is 4-6mm.
Further, there is concave point on the upper and lower surface of described plate body.
Further, described concave point is uniformly distributed.
Beneficial effect of the present invention is: XPS extruded sheet surface of the present invention produces concave-convex effect, favourable stickup, the tensile bond strength of itself and bonding adhesive and plastering mortar, water-fast and freeze-thawing resistant intensity, all at more than 0.25MPa, substantially increase the cohesion of system, increase reliability.
Accompanying drawing explanation
Figure 1 shows that the elevation of the utility model XPS extruded sheet;
Figure 2 shows that the lateral view of the utility model XPS extruded sheet.
Detailed description of the invention
Hereafter will describe the utility model specific embodiment in detail in conjunction with concrete accompanying drawing.It should be noted that the combination of technical characteristic or the technical characteristic described in following embodiment should not be considered to isolated, they can mutually be combined thus be reached better technique effect.In the accompanying drawing of following embodiment, the identical label that each accompanying drawing occurs represents identical feature or parts, can be applicable in different embodiment.
Figure 1 shows that the elevation of the utility model XPS extruded sheet; Figure 2 shows that the lateral view of the utility model XPS extruded sheet.As shown in Figure 1, 2, the invention provides a kind of XPS extruded sheet, comprise plate body 1, plate body 1 one side is with metope contact bonding, and another side contacts bonding with wiping one's face.Plate body 1 two sides is provided with groove 2, and groove 2 is rectangular channel, runs through plate face, layout parallel to each other.The width of groove 2 is set to 2mm, also can be set to 3mm; The degree of depth of groove 2 is set to 3mm, and also can be 4mm or 5mm, the spacing between groove 2 be set to 4cm, also can be 5cm or 6cm.After plate face being arranged groove 2, effectively can increase plate face with metope and the tension force between wiping one's face, thus add stability and the safety of XPS warming plate.These structures effectively can improve the adhesive property of warming plate.Plate body 1 also arranges concave point 3, and concave point 3 is evenly arranged on plate face, increases the tension force between contact surface further, the stability of warming plate and safety are improved further.
XPS extruded sheet of the present invention surface produces concave-convex effect, favourable stickup, and the tensile bond strength of itself and bonding adhesive and plastering mortar, water-fast and freeze-thawing resistant intensity, all at more than 0.25MPa, substantially increase the cohesion of system, increase reliability.
Although given embodiments more of the present utility model, it will be understood by those of skill in the art that when not departing from the utility model spirit herein, can change embodiment herein.Above-described embodiment is exemplary, should using embodiment herein as the restriction of the utility model interest field.
