Abstract
The invention discloses a preparation method of a gypsum bedrock cotton fiber insulation board, and belongs to the field of insulation boards. The preparation method comprises the following steps: a rock wool material, a gypsum cement mixture and a modified hybrid adhesive are mixed and stirred, and then the mixture is injected into a stainless steel die to be molded and dried, so as to obtain the gypsum bedrock cotton fiber insulation board. According to the preparation method of the gypsum bedrock cotton fiber insulation board, provided by the invention, rock wool, gypsum and cement which are adopted as the main raw materials, and are inorganic materials, thereby being non-toxic and pollution-free, so that the prepared inorganic and non-combustible thermal insulation material can replace the conventional flammable organic thermal insulation material in the market, the problem that the building exterior wall external insulation system is difficult to prevent fire is solved, and great significance on the city safety is further achieved.
Description
Technical field
The invention discloses a kind of preparation method of gypsum base rock wool fibers warming plate, belong to warming plate field.
Background technology
Rock wool is a kind of high-quality and efficient lagging material, it has good heat insulating, sound insulation and sound absorbing capabilities, compared with traditional lagging material, have that density is little, thermal conductivity is low, do not burn, nontoxic, applied widely, the outstanding advantages such as stable chemical performance, life cycle are long of preventing fires, be the desirable lagging material of generally acknowledging both at home and abroad.Abroad, especially employ asbestos product in a large number in European construction market, consumption is at more than 20kg per capita in Northern Europe, and the U.S. per capita consumption is that 510kg is due to fire safety problem, in the U.S., rock mineral wool accounts for 70%, and the architectural exterior insulation high more than 22m in Germany almost all adopts rock wool heat-preservation material.But in China, rock wool is also lower as the rate of utilization of building thermal insulation material, be mainly used in the aspects such as the thermal insulation of the light plate of energy petrochemical complex, shipping industry and building, fire prevention, sound insulation, and apply seldom in covil construction, particularly the application of external wall outer insulation is domestic is still blank.Along with organic wall heat insulation material be widely used in public with covil construction since, in rapid succession, the fire resistance of lagging material causes the great attention of various circles of society to Fire Accidents for Buildings.Rock wool has the outstanding advantages such as density is little, thermal conductivity is low, do not burn, and is desirable inorganic heat insulation material.
Organic insulation material (PS, PU) in the market, fire-protection rating is lower.Such as, polystyrene foamed plastics (EPS) burning-point is 346, spontaneous ignition temperature is that 490 external heat sources pass the thick polymkeric substance plastering mortar of 35mm or titanium zinc alloy plate reaches 490, only need several minutes just can cause the chain burning of porous plastics spontaneous combustion EPS energy, very fast melting after the burning of flame retardant grade porous plastics, droplet temperature is far above 490, molten drop drips to part, cause again porous plastics spontaneous combustion, form chain burning, this chain burning is the most fearful part of porous plastics.And the maximum operation (service) temperature of rock wool is more than 650 DEG C, its fusing point is more than 1000 DEG C, and when running into fire, rock-wool heat insulation plate can not cause smog or cause Mars, also can not drip, cause fire spreading.Even if also can not discharge at high operating temperatures environment and the unfavorable or harmful gas of human body.Therefore, rock wool is as the lagging material of external wall, and its fire resistance is also very superior.
Summary of the invention
The technical problem that the present invention mainly solves: for current organic insulation material (PS, PU), fire-protection rating is lower, external heat source reaches burning-point through flame-retardant polymer plastering mortar, only need several minutes just can cause porous plastics spontaneous combustion and cause chain burning, and organic insulation material in the fabrication process, likely there is chemical leakage and make
Become poisoning, fire, the harm of blast, provide a kind of preparation method of gypsum base rock wool fibers warming plate, the present invention's rock wool material, gypsam cement and modification composite adhesive mix and blend, inject shaping and dry the gypsum base rock wool fibers warming plate of stainless steel mould, the rock wool that the present invention adopts, gypsum, cement is main raw material, it is all inorganic materials, nontoxic, pollution-free, obtained inorganic non-combustible lagging material substitutes existing flammable organic insulation material on market, the problem that the fire prevention of external wall external insulation system is difficult can be solved, urban safety is significant.
