Abstract
The invention discloses a method for preventing polyurethane of a stone polyurethane composite board from contaminating a stone surface. A combined material is sprayed at the periphery of a stone thin plate through a material distributing system, wherein the combined material is quickly foamed and cured at the periphery of the stone thin plate, so that the combined material which penetrates into a plate seam part cannot reach the bottom of the plate seam, and the stone surface is completely free of contamination of the polyurethane.
Description
Technical field
Patent of the present invention relates to a kind of processing method, especially a kind of method solving stone material Rigid foam polyurethane polyurethane pollution stone material surface.
Background technology
Polyurethane is the insulation material that performance is best in the world at present, hard polyaminoester has that quality is light, thermal conductivity factor is low, good heat resistance, ageing-resistant, easily and other base materials bond, burning does not produce the excellent properties such as molten drop, be widely used in external thermal insulation system, one of polyurethane thermal insulation and decoration composite plate development trend becoming external wall outer insulation.But in production process, how avoiding polyurethane to penetrate into stone surface when foaming by plate seam is puzzlement stone material polyurethane thermal-insulation clad plate industry a great problem for many years.
Summary of the invention
In order to solve current Problems existing, the invention provides a kind of method solving stone material Rigid foam polyurethane polyurethane pollution stone material surface.
Patent of the present invention solves the technical scheme that its technical problem adopts:
A) before original process equipment, a cloth system is increased.By the setting to cloth system, only at the surrounding spraying premixed systems of thin slabstone, the width of spraying is between 20mm-100mm.
B) adopt laterally to rise and send out premixed systems fireballing.When thin slabstone premixed systems under out-of-date spray, premixed systems rises fast to be sent out, and the premixed systems infiltrating intermediate plate seam gap fails to arrive plate seam bottom, has just completed preliminary foaming.
Premixed systems is two component polyurethane premixed systems, has and laterally works the feature that the speed of sending out is fast, the primary solidification time is short.
The present invention, by increasing by a procedure on original Process ba-sis, solves the problem that the contaminated rear cleaning of stone surface is difficult, simply more convenient to operate, eliminates the cumbersome process of pre-process and post-process.When the spacing of plate seam is between 2-5mm, premixed systems also can not leak into plate seam bottom.After compound completes, plate surface pollutes without polyurethane completely.
Detailed description of the invention
Embodiment 1
Carry out compound to sleek stone material thin plate, be of a size of 600mm*600mm, two pieces of thin slabstones can parallelly be put on a moving belt, and after stone material alignment is ajusted, the plate seam between sheet material is 2mm.The spraying width adjustment of adjustment cloth system is 20mm, when thin slabstone arrives the position of cloth system setting, cloth system carries out spraying dual-component polyurethane premixed systems to the surrounding of thin slabstone, after spraying, premixed systems 2 rises in second and sends out, premixed systems trickling speed is slower than the time of laterally rising and sending out, and when the premixed systems on intermediate plate seam both sides contacts with each other, premixed systems does not leak into plate seam bottom, in 10 seconds premixed systems primary solidification complete, enter next procedure and carry out polyurethane coating.
Embodiment 2
Compound is carried out to bush-hammered face thin slabstone, be of a size of 600mm*800mm, thin slabstone traverse is on conveyer belt, align with one end of conveyer belt in thin slabstone one end, the other end is filled by polyurethane plate, plate between thin slabstone and polyurethane plate stitches 5mm, the spraying width adjustment of adjustment cloth system is 30mm, conveyer belt drives thin slabstone forward, during the position that thin slabstone sets to cloth system, cloth system carries out spraying dual-component polyurethane premixed systems to the surrounding of thin slabstone, after spray is lower, premixed systems 2 rises in second and sends out, premixed systems trickling speed is slower than the time of laterally rising and sending out, when the premixed systems on intermediate plate seam both sides contacts with each other, premixed systems does not leak into plate seam bottom, in 15 seconds, premixed systems primary solidification completes, enter next procedure and carry out polyurethane coating.
Claims (4)
1. solving the method that stone material Rigid foam polyurethane polyurethane pollutes stone material surface, it is characterized in that carrying out spraying premixed systems by increasing by a procedure to the surrounding of thin slabstone, prevent polyurethane from polluting stone surface.
2. a kind of method solving stone material Rigid foam polyurethane polyurethane pollution stone material surface according to claim 1, is characterized in that: premixed systems has laterally to rise to be sent out soon, the feature that the primary solidification time is short.
3. a kind of method solving stone material Rigid foam polyurethane polyurethane pollution stone material surface according to claim 1, is characterized in that: premixed systems is sprayed by cloth system.
4. a kind of method solving stone material Rigid foam polyurethane polyurethane pollution stone material surface according to claim 1, is characterized in that: the spraying width of cloth system is between 20mm-120mm.
