Abstract
The invention discloses a kind of fire door core material, described inner core main component is expanded polystyrene veneer perlite particle, magnesium chloride saltwater brine, magnesium oxide light burnt powder, hydrophobizing agent and coal smoke powder; Described perlite particle is 100 parts, magnesium chloride saltwater brine is 55 parts, magnesium oxide light burnt powder is 70 parts, hydrophobizing agent is 3.5 parts, coal smoke powder is 5 parts.It is seamless that the present invention efficiently solves fireproof door leaf inner core filling periphery, stopped the mortal wound that fire door heat insulationly easily can not wear fire.The inner core material of this formula also efficiently solves the problem that fire door inner core returns halogen moisture absorption and deformation.The pearlstone board cost of producing by this technical recipe and technology is low, production efficiency is high, the different compression ratio of the sheet material of different thickness, its density is kept consistency, meets Ministry of Public Security's fire product conformity assessment center about the conforming requirement of fire-proof product processing performance.
Description
Technical field
The present invention relates to a kind of inner core material, particularly a kind of fire door core material and manufacture method thereof.
Background technology
The inner core packing material of fire-proof wooden door, normal employing mineral substance filamentary material.As mineral wool, rock wool, glass fibre, aluminosilicate fiber cotton etc.The advantage of these materials is that resistance to elevated temperatures is good, but shortcoming is also obviously, and the main drawback of mineral substance fiber is:
(1) fibre dust causes healthy harm to operator, as respiratory tract disease with skin is dry itches; And the environmental pollution of Workplace can be caused.
(2) fire is once after occurring, and the dust that mineral substance cellucotton powder produces fills the air diffusion in scene of fire, masses suffering from disaster and firefighter is caused to the grievous injury of respiratory system.
(3) because fiber substance rigidity is very poor, door leaf, in keying uses, because of the situation that vibrations can cause fiber substance gradually to wriggle, makes the formation space, top of door leaf downwards in the course of time, thus causes fire door to lose fire-proof function.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of fire door core material and manufacture method thereof and solves when manufacturing existing fire door core material the pollution of production environment and the problem such as grievous injury masses suffering from disaster and firefighter being caused when presence of fire to respiratory system.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of fire door core material, described inner core main component is expanded polystyrene veneer perlite particle, magnesium chloride saltwater brine, magnesium oxide light burnt powder, hydrophobizing agent and coal smoke powder; Described perlite particle is 100 parts, magnesium chloride saltwater brine is 55 parts, magnesium oxide light burnt powder is 70 parts, hydrophobizing agent is 3.5 parts, coal smoke powder is 5 parts.
The step of this fire door core material manufacture method is as follows:
(1) stirrer of low-speed running is adopted, by in 100 parts of expanded polystyrene veneer perlite particles and 70 parts of magnesium oxide light burnt powders and 5 parts of coal smoke powder input agitator kettles, start stirrer, then 55 portions of magnesium chloride saltwater brines are slowly poured in agitator kettle, stir 15 minutes, then add 3.5 parts of hydrophobizing agents, continue stirring 5 minutes, then blowing while stirring, finally will stir the mixing material that formed stored in for subsequent use in reserve cartridge;
(2) prepare the door leaf framework of a pair with fire-retardant wood composition, the mixing material in reserve cartridge to be poured in framework and evenly extravagant;
(3) in order to ensure the consistence of the density of the inner core material of various thickness specification, during regulation hot pressing compacting, the compression ratio of mixing material is 1:6;
(4) mixing material is sent in 300T thermocompressor by transporting belt and is suppressed, hot pressing temperature 90 DEG C-100 DEG C, and the time is 30 minutes, then exits press;
(5) plate having completed hot pressing needs ageing to lower the temperature process to normal temperature, can flow into next process after 24 hours;
(6) through above five processes, fire door core material completes.
By technique scheme, the invention has the beneficial effects as follows:
It is seamless that the present invention efficiently solves fireproof door leaf inner core filling periphery, stopped the mortal wound that fire door heat insulationly easily can not wear fire; The inner core material of this formula also efficiently solves the problem that fire door inner core returns halogen moisture absorption and deformation.The pearlstone board cost of producing by this technical recipe and technology is low, production efficiency is high, the different compression ratio of the sheet material of different thickness, its density is kept consistency, meets Ministry of Public Security's fire product conformity assessment center about the conforming requirement of fire-proof product processing performance.
Embodiment
The technique means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with particular content, setting forth the present invention further.
