Description

A kind of door core
Technical field
It is a kind of door core specifically the invention belongs to building materials technology field.
Background technology
Traditional halogen foaming doors core fire protecting performance is poor, fire of easily leaping up, returns halogen, and high temperature is easily carbonized, deforms, and in high-temperature heating During can discharge pernicious gas, have a strong impact on its service life, security performance and stability.Door panel market history of forming It is not long, kind substantially divides one, two, three generations：The first generation door panel of early stage is that sodium metasilicate is made up of high temperature hot pressing with bath of glass； Second generation door panel magnesia cement is also had and is produced using foam pattern as binding agent.These magnesite materials such as magnesia and Magnesium chloride (bittern) belongs to alkaline metal salt.After the water suction moisture absorption, sodium, magnesium isoreactivity cation and the metal hair in alkali metal salt Biochemical reaction, can corrode the steel-wood structure of fire resistant doorsets causes the rotten core of rotten door.Such as the burning of high temperature naked light, then severe toxicity can be more produced Dense smoke and fatal chlorine；Third generation perlite door panel quality has improved a lot but improvement of still needing.With epoch progress and section The development of skill, the measured perlite door panel new product of matter is also come out one after another.By country to the technical requirements of fire resistant doorsets quality inspection, Perlite door panel, should be not easy to break in production and handling process it is necessary to have intensity higher；Perlite door panel should be able to It is not loose not mashed that soaked guarantee is stood for a long time；The component materials such as binding agent curing agent should could protect door body steel plate in neutrality The not rotten rotten core of door is not corroded；Meanwhile, door panel should also possess good hydrophobicity performance, and doing water absorption test will can be presented lotus leaf Dewdrop effect, so could effectively prevent water suction from getting damp, and favourable to reduce plate glue consumption, can just economize on resources reduces cost.Pearl The technological progress of rock door panel is most important for the sound development of fire resistant doorsets industry.Current China is most of organic or compound resistance Combustion agent has toxicity, and material combustion after fire retardant treatment can produce more toxic gases, do harm to huamn body；Resistance The resistance leachability for firing agent is poor, and lasting flame retardant effect is poor, and the incorporation of inorganic vermiculite causes negative shadow to fire-resistant door core bending property Ring.
