Abstract
The present invention discloses making process of fireproof inorganic door core and door leaf. The fireproof inorganic door core and door leaf is made with expended perlite 30 wt%, talcum powder 10 wt%, magnesia 20 wt%, magnesium chloride 20 wt%, urea formaldehyde glue 10 wt%, polyester glue 5 wt%, alum 3 wt%, potassium permanganate 1 wt%, and ferrous sulfate 1 wt%, and through mixing, hot pressing at pressure of 200-400 tons and temperature of 100-350 deg.c for 60-120 min. The fireproof inorganic door core and door leaf has high fireproof and heat isolating performance.
Description
One. technical field:
The manufacturing process of inorganic non-combustible door core of the present invention and fire-proof door leaf thereof,, what relate to is building material technical field.Be applied to the fire door of steel, wooden and steel wooden structures.
Two. background technology:
Along with developing rapidly of China's high-rise, steel miscellaneous, wooden, fire-retardant material such as steel is wooden, matrix material and fire door constantly emerge in large numbers.Because existing fire-retardant material price height (aluminum silicate ceramic cotton), fire door Market competition, some enterprises adopt the material substitution of price low (as rock wool), fireproof poor performance for profit, and the fire door quality problems that cause thus are very serious.
The enterprise of the fire door of China's production at present has family more than 400 approximately.The steel of being produced, fire door inner core filler major part wooden and the steel wooden structures all adopt the aluminum silicate ceramic cotton, but the interests of a batch of fire door manufacturing enterprise for self are arranged, but adopt matter time, rock wool that valency is low to do inner core filler etc., be difficult to guarantee the visual appearance and the fire performance of fire door as fire-proof heat-insulating material.Because aluminum silicate ceramic cotton, rock wool, though belong to inorganic product, they all are fibrous substances, and human body, environment are had serious harm, are unfavorable for HUMAN HEALTH.Prove through scientific verification that at home and abroad long-term the contact with such material can make human body produce silicosis, disease such as carcinogenic, early have abroad and begin to forbid or place restrictions on use.
Three. summary of the invention:
The objective of the invention is to overcome above-mentioned defective, provide that a kind of reliable in quality is stable, price is low, technology is simple, and can carry out pipelining production, human body and environment are not had the inorganic non-combustible fire door core and the door leaf of harm.
It is characterized in that: its proportioning (counting by weight percentage) is:
Pearlstone 30%,
Talcum powder 10%,
Magnesium oxide 20%,
Magnesium chloride 20%,
Urine aldehyde glue 10%,
Polyester glue 5%,
Alum 3%,
Potassium permanganate 1%,
Ferrous sulfate 1%;
Above raw material is commercially available,
Its production technique is: at first pearlstone, talcum powder, magnesium oxide, magnesium chloride, urine aldehyde glue, polyester glue, alum, potassium permanganate are placed in the stirrer after the mixing and stirring as inorganic non-combustible door core raw material by the formula rate weighing, pour in the materials-stored box, prepare against when manufacturing door panel and use; In the steel door leaf mould device, put into the aluminium alloy supporting plate of door leaf and installed the stiffening web of hinge, Steel Facing under the door and window of lock box, inorganic non-combustible door core raw material is mated formation equably in the mould device of steel door leaf, place again in the preformer of door panel material and carry out precompressed with 200-400 ton pressure, precompressed is placed on the last Steel Facing that the travelling belt place adds a cover door leaf, send into the door leaf thermocompressor and carry out hot pressing, pressure is the 100-150 ton, time is 60-120 minute, temperature 100-350 ℃, then, send into travelling belt, separate aluminium alloy supporting plate (supporting plate is returned the preformer place to be used fully again), take off the door leaf that has pressed from travelling belt again and decorate processing treatment, Hardware fittings such as hinge and lock are installed, to decorate mounted door leaf fully and test, go into stockyard after the assay was approved.
The advantage of implementing after this technology is: quality is good, price is low, fire insulation performance is high, inorganic non-combustible, harmless, satisfy the technical requirements of heat pressing process simultaneously, reached the requirement of manufacturing door panel material and door leaf, and can carry out modern pipelining and produce fire-proof door leaf, thereby made the quality of production of fire door stable, fire endurance is reliable, standard compliant specified requirement.
