Description
Technical field
The present invention relates to frie retardant coating technology, particularly novel fireproof coating exclusively for tunnel.
Background technology
Continuous expansion along with the development of engineering construction and communication and human being's production, life requirement, different kinds of railways, highway communication tunnel and sub. (abbreviation subway) development is rapid, and the length overall to whole Europe area traffic tunnel in 2000 surpasses 10,000 ten thousand km according to statistics; In for the second time national highway generaI investigation, China's vcehicular tunnel above county level is built length overall 5,500,000 km nearly, but when road conditions are improved, road traffic flow and vehicle and conveying objects thereof change also very greatly, not only increase the fire risk of traffic tunnel, but also caused many serious fire failures.
Tunnel fire hazard is serious threat people's safety of life and property not only, and may be to traffic facilities, and the Human's production activity causes considerable damage.Therefore, various countries have all dropped into suitable strength tunnel fire hazard and fire protection have been carried out than extensive studies over nearly 20 years, and have obtained certain achievement, have formulated some technical requirementss and standard.But compare with these requirements and standard; still there is huge spread in China in the tunnel fire hazard protection; especially lack the high performance fire-proof coating for tunnels that tunnel RABT fire testing that fire resistance meets regulation among the I class tunnel of regulation among China GB50016-2006 " Code for fire protection design of buildings " and the GA/T714-2007 " member with flameproof protection material be rapidly heated fire testing method " is tested, that is to say that China still can not produce the fire-proof coating for tunnels that meets above-mentioned two standards at present.
Summary of the invention
The purpose of this invention is to provide the tunnel RABT fire testing test of a kind of I class tunnel that meets China GB50016-2006 " Code for fire protection design of buildings " regulation and GA/T714-2007 " member with flameproof protection material be rapidly heated fire testing method " regulation, have good fire performance, cohesiveness by force, be easy to the novel fireproof coating exclusively for tunnel of constructing operation, high comprehensive performance.
The present invention adopts technical scheme to be: novel fireproof coating exclusively for tunnel comprises following weight percent raw material:
High-alumina cement and silicate cement 30～40%,
Expanded vermiculite 17～26%,
Pearlstone 7～13%,
Mica 4.5～8%,
Sepiolite 4～10%,
Wollastonite powder 4～10%,
Glass hollow float bead 3.5～4.5%,
Aluminium hydroxide 3.5～5.8%,
Magnesium hydroxide 5～6.2%,
Poly-bright rare staple fibre 0.2～0.4%,
High efficiency water reducing agent 0.2～0.3%,
Redispersable latex powder 4～10%;
Best proportioning is following weight percent:
High-alumina cement and silicate cement 39%,
Expanded vermiculite 18%,
Pearlstone 11%,
Mica 6%,
Sepiolite 4%,
Wollastonite powder 4%,
Glass hollow float bead 4%,
Aluminium hydroxide 3.5%,
Oxygen magnesium oxide 5%,
Poly-bright rare staple fibre 0.2%,
High efficiency water reducing agent 0.3%,
Redispersable latex powder 5%;
High-alumina cement is 1 to 2 with silicate cement weight ratio the best;
High-alumina cement is 42.5#, and silicate cement also is 42.5#.
The present invention is based on new prescription and the frie retardant coating of the excellent property researched and developed, compared with prior art, the present invention is owing to improve and optimized raw-material selection, optimized the proportioning of each component, thereby made novel fireproof coating exclusively for tunnel, significantly improved the performance of frie retardant coating, positively effect shows following several aspect:
(1) fire endurance significantly improves.The fireproof coating exclusively for tunnel that the present invention researched and developed, when coat-thickness 10mm, the coating fire endurance can reach and be 120min to the maximum, substantially exceeds the fire endurance of 90min that present national standard requires; During coat-thickness 20mm, its fire endurance can reach 240min.Domestic other like product, the thickness of the required coating of fire endurance 120min then are 20mm even more.
(2) effectively reduce coat-thickness.Because the raising of fire endurance makes less coating can realize fire-resistant fire prevention target, thereby weight of coated paint significantly reduces, and significantly reduced use cost.
(3) cohesive strength is big.Because the use of redispersable latex powder and other raw material makes cohesive strength of the present invention greater than 0.4MPa, reach 0.6～0.8Mpa, and the cohesive strength of like product is generally 0.1MPa.
(4), high comprehensive performance.This coating application is convenient, and workability is good; The starting material that product is selected for use do not contain harmful materials such as asbestos, compliance with environmental protection requirements; Moisture-resistance is good; Long curved tunnel had tangible sound-absorbing, erasure effect; To concrete strong adhesion.
(5), industrialization prospect is good.The product of research and development can carry out the industrialization continuous production, is with a wide range of applications, and can produce better economic and social benefit.
