Abstract

A kind of elevator shaft sound absorbing layer, comprises: hoistway wall deck and complete water base soft foamed polyurethane layer from inside to outside.This elevator shaft sound absorbing layer has excellent sound-absorbing, anti-acoustic capability.

Description

A kind of elevator shaft sound absorbing layer
Technical field
The utility model relates to a kind of architectural structure system, relates to a kind of elevator shaft sound absorbing layer particularly.
Background technology
Elevator shaft sound absorbing layer is the topping being arranged at elevator shaft, plays the effects such as sound insulation and noise reduction.Existing employing glass wool board, as the abatvoix of stock, in order to prevent glass fiber to be scattered, needs to enclose the entrant sound fabrics such as layer of non-woven fabric in plate face.So not only produce and complicated construction technique, and affect noise reduction and fireproof performance.
Chinese patent CN202321882U discloses a kind of wallboard for lift car of passenger lift, comprise panel and cover plate, have cavity structure before panel and cover plate, be provided with honeycomb card board and be filled with polyurethane foam glue-line in die cavity, the outer surface of panel has one deck self-cleaning layer.Its shortcoming is that metope can not be moist, can not run into strong wind, and metope will arrive more than-5 degree and just can construct.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of novel elevator shaft sound absorbing layer, has excellent sound-absorbing, anti-acoustic capability.
For achieving the above object, the utility model adopts following technical scheme:
A kind of elevator shaft sound absorbing layer, comprise from inside to outside: hoistway wall deck and complete water base soft foamed polyurethane layer, wherein, described complete water base soft foamed polyurethane layer direct forming is on described hoistway wall deck.
Described complete water base soft foamed polyurethane layer, direct spraying to form on deck and fits tightly with it, without the need to being prefabricated into special shape, also fitting tightly with deck without the need to being realized by adhesive, being suitable for the convenience that elevator shaft works site operation installs streamlined operation.
In the utility model, the thickness of described complete water base soft foamed polyurethane layer is about 5cm.
The important technological parameters of described complete water base soft foamed polyurethane layer comprises: density of material 8kg/m 3thickness is about 5cm, elongation at break and drawing coefficient are respectively 16.44%, 40.4kPa (GB/T 6344), water absorption rate 3vol% (GB/T 8810), hydrophobic rate 99.6% (GB/T 10299-1988), coefficient of thermal conductivity 0.04 W/ (mK) (GB/T 10291-1988), total carbon content TVOC 333.1 μ gC/g (VDA277), fire-protection rating core B1, B2 level, composite A-grade.
Described complete water base soft blown polyurethane materials is the complete water base soft blown polyurethane materials of richness god adopting Fu Shen company to rely on North America and the exploitation of European high performance polymer material application technical research center research and development strength.Specifically, it is stoste based on polyethers, polyester, take amine as catalyzer, with water-soluble silicon-carbon type silicone oil (abbreviation organosilicon) for foam stabilizer, being blowing agent with deionized water, take phosphorus-containing compound as the macromolecular compound that the polyether polyols raw polyol that is mixed to form of fire retardant and isocyanates carry out exothermic reaction generation.This material is complete water base foaming system, this make shaping after macromolecular material hydrophilic group distribute more balanced in the material with hydrophobic group; In addition, this material is open-celled structure, thermal-insulating waterproof superior performance, without Small molecular noxious gas emission, and strong mechanical property, durable in use, with the building same life-span.
The invention has the beneficial effects as follows:
Elevator shaft sound absorbing layer of the present invention has the excellent performance such as sound-absorbing, noise reduction.The anti-flammability of described elevator shaft sound absorbing layer can reach the advantage such as B2 rank, TVOC (total carbon content) 333.1 μ gC/g.
Compared with traditional electrical stair shaft, elevator shaft sound absorbing layer of the present utility model is thermal-insulating waterproof integral structure, and deck wherein and complete water base soft foamed polyurethane layer fit tightly, and bonding force is strong, without the need to by adhesive, realize thermal-insulating waterproof function very well and have good sound insulation, anti-acoustic capability; Secondly, the compound structure light weight of deck and complete water base soft foamed polyurethane layer, can effectively reduce elevator shaft deformational stress load, strengthens overall structure toughness and cracking resistance sex change.
With Conventional insulation as compared with extruded sheet, polyphenyl plate, mineral wool, vitrification micropearl morttar etc., complete water base soft polyurathamc heat insulating material coefficient of thermal conductivity of the present utility model is little, high insulating effect, low-carbon (LC), green, environmental protection.
The mechanical stretch intensity of complete water base soft polyurathamc heat insulating material of the present utility model is high, and optimum with deck cementability, and with deck without cold-heat bridge, crack resistance is good, free from flaw, and this is that Conventional insulation cannot realize.The rate of closed hole of complete water base soft polyurathamc heat insulating material of the present utility model is high, can reach more than 92% (GB10799), and sound insulation, anti-acoustic capability are good, and moisture absorption moisture resistance is good, for elevator shaft, can realize thermal-insulating waterproof integration.
Other heat insulating material relatively, complete water base soft polyurathamc heat insulating material direct spraying of the present utility model forms on deck and forms complete water base soft foamed polyurethane layer, without the need to being prefabricated into special shape, also without the need to being fitted tightly by adhesive and deck, its convenience in forming materials, construction and installation is its unrivaled advantage.
