Abstract

An enhanced polymer cement polyphenylene adding storey insulation plate is applicable to the internal or external insulation of exterior walls in civil houses, office occupancy, industrial architectures, hospitals, kindergartens and public buildings. Two surface layers of the utility model are made of polymer emulsion, inorganic powder and polymer cement mortar bed formed by additives, the middle parts of the front and back layers, which is slightly near to the surface are provided respectively with glass fiber grid cloth layers, 2 to 3 polyphenylene insulation layers are arranged on the inner sides of the two surface layers; the utility model is characterized in that: every two polyphenylene insulation layers is provided with mutually staggered transverse holes, one more polymer cement mortar bed is arranged respectively in the hole and between every two polyphenylene insulation layers, which is integrated firmly with the polymer cement mortar bed of the two surface layers so as to form a framework, and a polyphenylene plate is embedded therein to form an integral whole. The advantages of the utility model lies in that, the integral stiffness and intensity of the insulation plate is greatly strengthened, the wall cracking problem caused by stress concentration is solved, and the utility has flame retardant ability and is harmless to people and is environment friendly.

Description

Strengthen the polymer cement polyphenyl and add a layer warming plate

Technical field

The utility model relates to a kind of enhancing polymer cement polyphenyl and adds a layer warming plate, belongs to architectural decoration material field, is applicable to the interior insulation or the outer insulation of exterior walls such as residential houses, office occupancy, industrial construction, hospital, kindergarten and utilities building.

Background technology

The outer wall inner insulation material that uses has the refinforced cement polyphenylene heat insulation slab at present, 50% of area is used in insulation in accounting for, water resistance is relatively poor, this plate is provided with frame, be two-layer cement folder one deck polyphenyl plate structure, increased the heat transfer layer of heat-preserving wall, the phenomenon of wet lattice seal piecemeal can appear in exterior wall, because of low, the lacking toughness of cement perlite surface layer intensity, to meet to knock, bump and easily cause warming plate to damage, its surface thickness is inhomogeneous, the warming plate shrinkage strain is inhomogeneous, cause stress concentration, easily produce the crack, influence heat insulation function; Can not follow closely, hang thing during existing stickup polyphenyl plate finishing onboard, can not bonding and punching; The subject matter that grid cloth strengthens the existence such as heat insulating material for external of smearing anticracking grout is: the insulation layer bulk strength is low, and the internal stress skewness easily causes cracking, and the insulation layer shock resistance is poor, can not carry out constructions such as exterior wall tile fixing or stone material dry suspending.

Summary of the invention

The purpose of this utility model is, technical problems such as, easy fracture low at the intensity of existing warming plate provide a kind of enhancing polymer cement polyphenyl to add a layer warming plate; It is as follows to solve the problems of the technologies described above the technical measures of being taked: frame around the existing warming plate of cancellation, two surface layers are that macromolecule emulsion and inorganic powder mix and stir the polymer cement mortar layer that forms, the outer fiberglass gridding cloth layer that is respectively equipped with in the centre of two surface layers, its inboard is 2～3 strata benzene insulation layers, and on each polyphenyl insulation layer, be respectively equipped with the transverse holes that staggers mutually, increase the one layer of polymeric cement sand bed in the hole and between every two-layer polyphenyl insulation layer, between each layer with grouting machine with forming machine is once-combined forms; Advantage of the present utility model: because frame around having removed, cancelled heat transfer layer, the phenomenon that wet lattice seal piecemeal can not occur, two surface layers, the polymer mortar layer that adds in layer and the transverse holes have constituted whole skeleton, the polyphenyl insulation layer is embedded in the skeleton, thereby strengthened the bulk strength and the rigidity of warming plate, increased heat-insulating property simultaneously; Solved traditional warming plate stress concentrate the wall crazing cause, not water-fast, speed of application slow, to follow-up decorative engineering can not be on warming plate problems such as nail, extension and punching; Planeness is good, firm, durable; Human body there is not harm; Environmentally safe.

The specific embodiment

In conjunction with the accompanying drawings structure of the present utility model and embodiment are described as follows: adding layer with one deck is example, two surface layers are macromolecule emulsion and cement, sand, flyash, the polymer cement mortar layer 2 that additive constitutes, be provided with layer of glass grid layer of cloth 1 from 1/3～1/4 place, surface, to increase toughness and rigidity, two surface layer inboards are respectively polyphenyl insulation layer 3, the preincubation layer is provided with 5 cross through hole, back insulation layer is provided with 8 cross through hole, the center line in hole is the setting of staggering, avoid forming heat transfer layer, as Fig. 4, shown in Figure 5, both increased the intensity of warming plate, rigidity, keep heat-insulating property again, be provided with polymer cement mortar layer 2 in the hole and between the two polyphenyl insulation layers.

Specification of the present utility model can be, and is long: 100～3900mm, wide: 100～1500mm is thick: 30～150mm, wherein surface layer and the thickness that adds layer are 5～10mm, the thickness of insulation layer changes with specification is different.

As follows through the experimental technique index, warming plate performance: surface density≤20kg/m ², equivalent thermal resistance 〉=0.9kg/m ², compoiste adhering intensity 〉=0.15MPa, compoiste adhering shear strength 〉=0.15Mpa, bending resistance load 〉=1.8GN, resistance to impact 〉=48 time are with body of wall adhesion strength 〉=0.15Mpa, with the affixed intensity 〉=0.3Mpa of body of wall; Polymer mortar performance: compressive strength 〉=10MPa, water-fast strength retention 70%, 15 strength retention 〉=70% of freeze thawing, moisture content≤4%, dry density≤1500kg/m ³, combustibility B1 level.

Meet Beijing's standard fully: DBJ01-30-2000 panels with interior insulating layer for external wall quality inspection and evaluation standard.
