Abstract
The invention provides a method for manufacturing a rubber sound-insulating heat-insulating floor slab at the normal temperature and pressure on the site. The rubber sound-insulating heat-insulating floor slab comprises a floor slab structural layer, a rubber particle layer, a cement mortar layer and a floor tile surface layer. The method is characterized by comprising the steps that after rubber particles mixed with environmentally-friendly non-toxic polyurethane glue are directly and evenly scraped and laid on the floor slab structural layer through a darby at the normal temperature and pressure, the rubber particles are densely pressed through a trowel, and geotextile is laid on the rubber particles; and surface layer materials such as floor tiles or marble are laid on the geotextile through cement mortar. Irregular polyhedral particles are selected as the rubber particles, the length of each particle ranges from 0.5mm to 8mm, the weight of the rubber particles accounts for 91-84% of the weight of the mixture between the rubber particles and the polyurethane glue, and the weight of the polyurethane glue accounts for 9-16% of the weight of the mixture between the rubber particles and the polyurethane glue. Compared with a manufacturing method of an existing foaming sound-insulating coiled material, the method has the remarkable advantages that a mortar leveling layer does not need to be formed on the structural layer, a concrete protective layer does not need to be deposited on the coiled material again, the floor height space is greatly saved, the load of a building body is reduced, and the construction period is shortened. The method is quite applicable to the field of the construction industry.
Description
Technical field
The present invention is applicable to building trade, and a kind of normal temperature and pressure manufactures the preparation method of rubber tolerant noise-insulating warm-keeping floor.
Background technology
At present, floor great majority are made for steel concrete, and soundproof effect is poor, and traditional method of sound insulation is paving glass wool or linoleum cloth, but use the sound insulation damping block of glass wool not withstand voltage because of glass wool, and effectiveness in vibration suppression is weak, is not accepted by market; Use the sound insulation damping block of linoleum cloth due to the pitch that wherein adds not environmentally, and poisonous, the product soundproof effect of preparation is poor, can not obtain the accreditation in market, is difficult to popularization.Along with people's living standard improves constantly, more and more higher to the requirement of comfortable for living, high requirement certainly will be proposed to sound isolation of floor performance, live privacy, comfortableness to meet people.
Present building trade floor sound insulation all uses the foaming coiled being made up different-thickness of elastomeric material substantially, and wherein general with the coiled material of high density polyethylene (HDPE) foaming or foam polyvinyl chloride, this coiled material is often that 3 ~ 5mm is thick.The standard of current building floor planeness is ± 20mm.Coiled material will be spread under such planeness standard, require first on floor slab structure, first to lay 20 ~ 30mm solid cement mortar levelling layer, after cured, coiled material is spread with erection method, because foaming kind coiled material tearing toughness is poor, walk above, be easy to foaming coiled be scratched, takes up when pushing away cement trolley, make soundproof course not have defening effect.The thick pea gravel concreten topping of one deck 40 ~ 60mm is poured into a mould in such requirement again on foaming coiled, ftracture for preventing cement layer, centre also will add layer of steel wire net, this work progress needs extreme care, workman need through professional training, such complicated construction operation, construction quality be can not be guaranteed, sound insulation coiled material is connecting method, easy formation overhead speaker, practical application shows that foaming sound insulation coiled material defening effect is undesirable and hollowing sound is large, airtight vesicle particularly in polyethylene or polyvinyl chloride foaming coiled, can break at the bubble of the weight such as upper surface concrete, soundproof course can be thinning, defening effect is caused to be lost, surface layer flooring is caused to press off quality problems such as splitting.
Publication number is that the application for a patent for invention of CN1851195A discloses a kind of building and domestic finishing material, and this material adopts EVA rubber foam to manufacture wall brick, floor tile, ceiling, wall corner line, stringcourse, mural painting brick and sound insulation materials; EVA rubber foam temperature-pressure after cutting out material puts into mould extruding or blow molding; Artificial caoutchouc clamp time decides according to the thickness of product, can between 5 seconds to 2 minutes; EVA rubber foam molding temperature is 120-300 DEG C; EVA rubber foam molding pressure is 2-30 ton; The preparation method of this material is complicated, process regulation difficulty, and product quality is difficult to control, and this foam water imbibition is high, and the decoration sound insulation materials of preparation is short for application life, and soundproof effect is poor.
