Abstract
The utility model relates to a polyurethane hard bubble sandwich integral thermal insulation light wallboard, which is characterized in that a polyurethane hard bubble sandwich layer is poured between two layers of concrete light wallboards. The product polyurethane hard bubble sandwich integral thermal insulation light wallboard of the utility model reduces vibration, insulates sound, and has flame proof, resistance to flame, thermal insulation, water resistance, good heat insulation, light wallboard, high specific strength, compact and solid structure and strong adaptive capacity to main body structure deformation, and the product service life of the utility model can reach 30 years under normal weather and temperature conditions.
Description
Technical field
The utility model relates to polyurethane hard bubble sandwiched integral heat preservation light wall board.
Background technology
Along with the progress in epoch, agenda has been put in continuable coordinated development, and building energy conservation becomes requisite measure, and exterior-wall heat insulation then is one of energy-conservation means of efficient construction, therefore receives much concern.
The incubation and thermal insulation function of wallboard is realized by the thermal insulation layer is set in the wall board structure.It is materials such as plane materiel, interior folder perlite or polystyrene foam or foaming resin that existing this class wallboard has with metal sheet or concrete or plank, also have and produce sandwiched plate, but the general heat-insulating property of these products is good inadequately, energy-saving effect is not ideal enough, what have is difficult to resist cold and hot summer weather, and heat-holding dampproof, sound insulation property are relatively poor; The intensity that has is low or heavy; Though metal clip central layer, plank wire lath sandwiched plate etc. have certain energy-saving effect, but the manufacturing cost height, can not one-shot forming, operation is many, wallboard intensity, bending resistance crushing resistance, fire-proof and water-proof performance are all stable inadequately, cause existing heat preservation construction material to be applied to that the building energy conservation project exists that relative cost height, construction technology are numerous and diverse, defectives such as technical data requirement and heat-holding dampproof performance deficiency.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of have high heat-holding dampproof, sound-proof fire-proof, antiseptic property, technology is simple, cost is low polyurethane hard bubble sandwiched integral heat preservation light wall board.
The utility model solves the problems of the technologies described above with following technical scheme:
Between two-layer concrete light wall panel, be cast with the polyurethane hard bubble sandwiched layer of one deck.
Use polyurethane hard bubble sandwiched integral heat preservation light wall board of the present utility model, compact conformation, firm is difficult for producing crack and infiltration, and water absorption rate is low, and is adiabatic good, the wallboard lightweight, and high specific strength, the vibration damping sound insulation, fire resistant flame retardant, thermal-insulating waterproof is remarkably productive.And it is strong to agent structure distortion adaptive capacity, when accompanying agent structure produces normal deformation, such as shrink, creep, during situation such as expansion, the hard-foam polyurethane heat insulation system can successively flexible gradual change, successively discharges stress, has effectively guaranteed stability, the durability of system, guarantee the omnibearing heat insulation effect of building complex region, can not produce crack or disengagement, under the normal climate temperature condition, can reach 30 years application life.And speed of application is fast when producing the utility model product, efficient is high, good environmental protection, and finished product has price advantage, and product of the present invention is real to be a kind of environment-friendly products of energy-saving and emission-reduction.
Description of drawings
Fig. 1 is a polyurethane hard bubble sandwiched integral heat preservation light wall board structural representation of the present utility model.Among Fig. 1: 1-Polyurethane is hard bubbled, 2-light weight concrete construction wallboard.
The specific embodiment
Polyurethane is the higher material of chemical stability, and is acidproof, alkaline-resisting, heat-resisting.Belong to no-solvent type, the high section bar material of non-fluorine lithium.Coefficient of thermal conductivity is 0.022～0.025W/ (mk), is excellent insulating, waterproof, every vapour, material that water absorption rate is low, is again a kind of natural adhesive material, can form continuous insulation layer with basic unit's body of wall strong bonded, effectively blocks heat bridge.And the polyurethane flexible deflection is bigger, strong to agent structure distortion adaptive capacity, when accompanying agent structure produces normal deformation, such as shrink, creep, during situation such as expansion, the hard-foam polyurethane heat insulation system meets successively flexible gradual change, successively discharge the principle of stress, thereby can not produce crack or disengagement.
The utility model has utilized the polyurethane foam material that Light trabs is had the good adsorption bonding characteristic, " material feeding foaming+original position bonding " the one-step shaping method of employing is finished the preparation of polyurethane hard bubble sandwiched integral heat preservation light wall board, and its structure is that the polyurethane hard bubble sandwiched layer of one deck is arranged between two-layer concrete light wall panel.
Use polyurethane hard bubble sandwiched integral heat preservation light wall board of the present utility model, have lightweight, the advantage of high specific strength.Measuring according to Guangxi inspection center of autonomous region, is that the concrete outer plate specification is Gq90-30-90 (lamina thickness 90mm), injects the thick hard polyurethane foam of 30mm interlayer, the result who is surveyed: thermal resistance R=1.26m under 28 ℃ the situation in cold and hot room temperature difference
2K/w, Coefficient K=0.72w/m
2K.
