Abstract

Disclosed is an A-60 rock wool for ships, wherein the principal raw materials include basalt or diabase, a predetermined proportion of aluminum oxide powder and other inorganic raw mineral materials. Its preparation consists of melting in induction furnaces or electrical resistance furnaces, and centrifuging to obtain the rock wool fiber whose chemical constituents (by weight percentage) include SiO2 38-45%, Al2O3 30-38%, Fe2O3 (containing FeO) 6.5-8%, CaO+MgO 5-8%, other constituents and 9.5-12%.

Description

A-60 level rock wool peculiar to vessel
Technical field
The present invention relates to rock wool technical field in the mineral fibre, especially relate to the rock wool that reaches A-60 level fire resistance rating requirement peculiar to vessel.
Background technology
Human life pact regulation according to the relevant fire prevention at sea of International Maritime Organizaton, for the insulation, the lagging material that use on the fire-resistant separated region of boats and ships A-60 level, its fire resisting construction must reach A-60 level fire resistance rating peculiar to vessel requirement, the i.e. fire-resistant separation test that need continue 1 hour by the intensification equation of regulation among the IMO.A754 of International Maritime Organizaton (18), its top temperature requires to reach 945 ℃, and this common rock wool to domestic production is to be beyond one's reach; The material that present domestic shipbuilding is used for the fire-resistant separation structure of A-60 level generally is to adopt aluminum silicate fiber, because of it can meet the resistance to elevated temperatures requirement and possess excellent heat insulation property requirement at high temperature; But the production of aluminum silicate fiber is to adopt electric arc furnace fusion, compressed air spraying technology, products characteristics is that density height, Fibre diameter are thin, especially have the following fiber of diameter 1 μ m, this fine-fibered of crossing is easily sucked in the lung by the people, influence healthy, so stopped using aluminum silicate fiber in EU member country, and used special rock wool instead as the fire-resistant separation structure material of A-60 level; Not open because of technology, the prescription of producing this rock wool, also have no way of knowing.
Summary of the invention
The objective of the invention is at the problems referred to above, it is little to provide a kind of resistance to elevated temperatures obviously to be better than under common rock wool, the high temperature heater wire velocity of variation, does not have fine-fibered again, and every performance all can satisfy the A-60 level rock wool peculiar to vessel of A-60 level fire resisting construction service requirements.
For achieving the above object, technical scheme of the present invention is such: a kind of A-60 level rock wool peculiar to vessel, its main raw material is basalt or diabase, add a certain proportion of aluminum oxide powder and other inorganic mineral raw materials, through mixed, fusion in induction furnace or resistance furnace, with four roller whizzers get rid of the silk rock wool fibers;
Its proportioning raw materials is that the weight percentage of benchmark is as follows in the total amount:
Basalt or diabase 70--85%
Aluminum oxide powder 15--25%
Rhombspar or Wingdale 0--5%
The chemical ingredients (by weight percentage) that makes its composition of rock wool is as follows:
SiO 2 38--45％
Al 2O 3 30--38％
Fe 2O 3(containing FeO) 6.5--8%
CaO+MgO 5--8％
Other components 9.5--12%
Said other components are meant the TiO of trace 2, K 2O, Na 2O, MnO 2, and sulphur, phosphorous oxides.
Adopt following structure to form fire-resistant separation by the rock wool that such scheme makes:
1) A-60 level bulkhead: two layers of thickness is that the rock cotton board staggered floor of 37.5mm is folded mutually, and stiffener coats the thick rock cotton board of 40mm, and density is 100kg/m 3
2) rock cotton board of A-60 level deck: 50mm, stiffener coats the thick rock cotton board of 40mm, and density is 100kg/m 3
3) A-30 level bulkhead: two layers of thickness is that the rock cotton board staggered floor of 25mm is folded mutually, and stiffener coats the thick rock cotton board of 40mm, and density is 100kg/m 3
Above-listed fire-resistant separation structure detects through the test of legal detection unit of country, the result meet the IMO of International Maritime Organizaton A.754 in (18) about the requirement of A-60 level deck and bulkhead and A-30 level bulkhead.
Owing to adopted technique scheme, the rock wool resistance to elevated temperatures that makes obviously improves than common rock wool, the heater wire velocity of variation is little under the high temperature, four roller whizzers got rid of a process reform compressed air spraying produce cross fine-fibered, the fire-resistant separation structure of being made up of material of the present invention of specialized designs makes every performance all meet the service requirements of the fire-resistant separation of A-60 level peculiar to vessel, can substitute import, saves foreign exchange, and technology of the present invention is simple, raw material is easy to get, and can reduce the shipbuilding n. cost.
