Description
Technical field
The utility model relates to a kind of fire preventing and heat insulating board, refers more particularly to a kind of exterior-wall heat insulation glass fiber reinforcement vertical hair rock cotton board.
Background technology
The fire preventing and heat insulating board occurred in the market is multifarious, and quality is uneven.
(1) phenolic foam board
Phenolic foam is a kind of novel difficulty combustion, fire prevention, low cigarette heat insulating material, and it adds by phenolic resins the closed pore rigid foam that fire retardant, smoke suppressant, blowing agent, curing compound and other auxiliary agents make.Its feature is difficult combustion, low cigarette, high temperature resistance distortion.It can cast-in-site foaming, and can be molded also can machining, can be made into sheet material, shell and various special-shaped product.There is the features such as foamed plastics type heat insulating material light weight, easy construction.Phenolic foam board, compared to polyphenyl foam plate and polyurethane foam board, has fire resistance relatively preferably, but still does not reach the requirement that civilian construction exterior insulation work fireproofing technique specifies.Phenolic foam board remains in easy efflorescence, the weakness such as warpage, mechanical strength are low, fragility, inextensibility and water absorption rate are high.In foaming process, adopt acid cure technique, in cystosepiment, residual acidity content crosses the problems such as high, will affect safety and the durability of outer heat preservation system and reinforced concrete structure.Over the past two years due to fire safety problem, many engineer applied phenolic board or phenolic fireproof isolation strip, there are serious quality problems in some engineering.Phenolic foam board still directly can not substitute polyphenyl foam plate and polyurethane foam board for external thermal insulation system to have expert to think.
(2) rock wool
Rock wool is with selected basalt or diabase for primary raw material, the accessory substances of additional some, and be blow molded into manmade inorganic fibre through high-temperature fusion is centrifugal, its main chemical composition is: SiO
2, Al
2o
3, MgO, CaO and Fe
2o
3.In rock wool fibers, add the Admixtures such as appropriate cementing agent, dust-proofing agent, hydrophober, can be made into the rock cotton board with some strength through press curing.Building energy conservation is one of most important application of rock wool.There is clear and definite regulation in a lot of country to building construction energy ezpenditure in the world.This regulation facilitates the application of rock wool in building energy conservation.Abroad, rock wool accounts for about 90% of rock wool total output with the fireproof performance of its excellence and heat-insulating property in Application in Building, and due to fire safety problem, polyphenyl plate system only accounts for 17% in the U.S., and rock wool, mineral wool account for 70%.The above house of Britain regulation 18m must use incombustible material as external-wall heat-insulation material.
Germany's clear stipulaties, forbids to use flammable heat insulating material more than the building of 22 m.Therefore, polyphenyl plate outer heat preservation system can only be used for being no more than in the building type of 22 m, and the building major part higher than 22 m uses rock wool outer heat preservation system.And for less than 22 132 building, when the polyphenyl plate thickness in polyphenyl plate outer heat preservation system is greater than 100 rnm, fire protection construction need be set again to meet building fire protection security regulations.
In China, the anticracking that comes off is the technical problem of puzzlement rock wool for external wall outer insulation always, and the ratio that rock wool uses as building thermal insulation material is lower, and successful case is less, and rock wool cannot obtain wide popularization and application in building energy saving field.When rock wool belt is as fire barrier materials'use, the Rock wool dust that cutting operation produces easily causes construction worker allergic.
(3) foam concrete
In recent years, foam concrete is very fast in the development of building heat preservation field, and the Application in Building area of current external wall insulation has reached 5,000,000 m2.At present, foam concrete product research comprises the combination property and a complete set of equipment research and development aspect that improve foam concrete.This material water absorption rate is higher, and coefficient of thermal conductivity is also comparatively large, and the climatic province (as cold district) higher for power conservation requirement is not suitable for, and easily produces cold-heat bridge and condensation.
(4) foam glass
Foam glass is by cullet, blowing agent, property-modifying additive and foamed promoter etc. the earliest, after the broken and Homogeneous phase mixing of fine powder, then through high temperature melting, and foaming, annealing and the inorganic non-metallic glass material made.The uniform bubble structure being l ~ 2 mm by a large amount of diameter forms.Foam glass is less in the application of external wall outer insulation field.
(5) inorganic heat insulation mortar
Using the light thermal-insulation particle of mineral-type as lightweight aggregate, add the dry powder and mortar be made up of cementitious material, anticrack additive and other inserts etc., there is certain thermal insulation, fireproof performance.This material brittle, water suction, quality is unstable, occurs insulation layer hollowing and causes the quality problems such as cracking due to hollowing.This series products is owing to being wet trade, and quality is difficult to control, and water absorption rate is higher simultaneously, and coefficient of thermal conductivity is also comparatively large, and climatic province such as severe cold and the cold district higher for power conservation requirement are not suitable for, and also easily produce cold-heat bridge and condensation.
Utility model content
