Abstract
The invention discloses a novel composite fire retardant module and a preparation method thereof. The novel composite fire retardant module has good fire retardance and water resistance and is also simple in processing technology, convenient in construction and nontoxic and nonharmful to the environment.
Description
Technical field
The present invention relates to a kind of fire retardant module and preparation method thereof, particularly a kind of Novel composite fire retardant module and preparation method thereof, belong to fire-proof sealing material technical field.
Background technology
Fire retardant module is the one in fire-proof sealing material, be mainly used in the shutoff of the holes such as electric wire, cable penetration and floor, and cable trench does the use of fire preventive partitions.Fire retardant module can effectively prevent electric wire, cable to be diffused into proximity space because heating is caught fire by hole, the electrical equipment that harm is connected, and then causes larger loss.At present, adopt fire retardant module to carry out shutoff to hole and cable trench fire preventive partitions exists following problem mostly in prior art: the first, water resistance is poor.Although some use the shutoff hole of fire retardant modules or fire preventive partitions through facing, steam still can enter finish coat, the fire retardant module soaked is expanded, loose, occurs decortication, falls the phenomenon of grain; The second, fire performance is poor.Because fire retardant module uses high score subclass tackiness agent in a large number, even if add fire retardant, still there is certain combustionproperty.3rd, complete processing is complicated.Owing to adopting polymer binder in a large number, the time of drying of fire retardant module is extended, in order to shorten time of drying, often adopting the mode of heated baking, both wasting the energy like this, too increasing labor capacity.
Summary of the invention
The object of the invention is to overcome defect of the prior art, a kind of Novel composite fire retardant module and preparation method thereof is provided, described Novel composite fire retardant module has well fire-resistant and water resistance, and simultaneously complete processing is simple, easy construction, nontoxic to environment.
The present invention is achieved by the following technical programs.
A kind of Novel composite fire retardant module, its moiety is as follows by mass parts:
Above-mentioned a kind of Novel composite fire retardant module, wherein, described composite adhesive is made up of organic composition and inorganic components, and described organic composition is one or both in latex powder and polyvinyl alcohol; Described inorganic components is at least two kinds in kaolin, wilkinite, PO42.5 cement and mica powder of wet process, and the mass ratio of described organic composition and inorganic components is 1:9-1:6.
Above-mentioned a kind of Novel composite fire retardant module, wherein, described water-resisting agent is one or more in silane water-resisting agent, inorganic aluminate water-proof agent and higher fatty acid water-resisting agent.
The preparation method of above-mentioned a kind of Novel composite fire retardant module, preparation process is as follows: (1) first prepares composite adhesive, organic composition in composite adhesive and inorganic components are added stirring and evenly mixing in V-type action of forced stirring mixing machine in proportion respectively, stirring velocity 8-10r/min, churning time 10-15min; (2) again by composite adhesive, expanded vermiculite, expanded graphite and water-resisting agent and water add in efficient coulter type mixer and stir, stirring velocity 45-55r/min, churning time 8-10min; (3) added by the compound stirred in the mould of smearing release agent in advance, carry out hydraulic pressure compression moulding, pressure 20MPa, pressurize 8s, then the demoulding at room temperature carries out drying, 7 days time of drying, can obtain described compound fire retardant module.
Expanded vermiculite in the compositing formula of Novel composite fire retardant module of the present invention and expanded graphite are flame resistant heat insulation material, the combustionproperty of fire retardant module can be reduced, improve the fire performance of fire retardant module, the particularly introducing of expanded graphite, when fire is occurred, can loosen to cable concussion the small hole produced well and carry out shutoff.Composite adhesive in formula is key of the present invention, and the compatibility of it and other component both ensure that and can play the fire performance of fire retardant module again the effect of high temperature adhesives when fire occurs, fire-proof and thermal-insulation addition material can not be come off because of expansion.Composite adhesive of the present invention mainly with latex powder and polyvinyl alcohol for organic system, using kaolin, wilkinite, PO42.5 cement and mica powder of wet process as inorganic system, organic system and inorganic system mixing form composite adhesive, composite adhesive can ensure the bonding of fire retardant module formed at normal temp in fire retardant module, can ensure again the performance of adhesive effect during high temperature.Composite adhesive can also change the drying mode that traditional fire retardant module relies on moisture evaporation, it absorbs moisture by the inorganic system of composite adhesive and solidifies, and accelerates the consumption of moisture, shortens drying cycle, simplify complete processing, thus reach the object of save energy and labor capacity.Water-resisting agent in formula can improve the water resistance of fire retardant module, and fire retardant module is met after water can not loose, distending, thus improves the water resistance of fire retardant module.Water uses as solvent in the present invention.
