Abstract
The present invention relates to a kind of novel fire-resistant-chipboard production technologies, belong to functional wood material scope.It is characterized in that first by adhesive (6%-15%) and polyphosphoric acid amine (5-10%), pentaerythrite (2-5%), melamine (2-5%), auxiliary agent (1-3.5%), smoke suppressant (2-5%), curing agent (1%), which is put into stir at low speed in instrument, uniformly to be mixed, it then again will be in mixture and wood shavings (60%) blender, so that mixture is uniformly mixed in wood shavings, then assembly is put into hot press and is hot pressed into plate.The invention, so that particieboard has the effect of fire-retardant, there is biggish meaning under the premise of guaranteeing particieboard mechanical property in practical applications.
Description
Technical field
The present invention relates to a kind of preparation of fire-resistant-chipboard, especially a kind of preparation of expansion type flame-retarding particieboard.
Background technique
Due to the shortage of timber resources, demand of the people to timber increasingly increases, so particieboard development is very rapid.
Particieboard has excellent performance: firstly, particieboard structure is uniform, and having good processing performance；Secondly, particieboard source
Extensively；Finally, particieboard production cost is low.But timber itself belongs to combustibles, the application of the particieboard of this problem limitation,
So studying fire-retardant shaving board becomes key especially.
Expansion shaving board is made of wood shavings, expansion type flame retardant, filler and various auxiliary agents.In combustion,
Carbon source in expansion type flame retardant mainly generates layer of charcoal, and dehydration occurs for acid source, promotes into charcoal, gas source generates non-ignitable or difficult
Combustion gas body, waters down oxygen concentration, to play the heat-insulated effect of fire insulation.Expansion shaving board not only has good fire-retardant effect
Fruit, and halogens is not contained, meet environmental requirement；Expansion shaving board is at low cost, and performance is good, increasingly by researcher
With the attention of enterprise, it is widely used at present.
The present invention is using wood shavings as matrix, and smoke suppressant is as a kind of filler, in the process of burning, reduces smoke
Amount escapes from the fire scene for people in fire and provides advantage, and smoke suppressant makes the flame-retardant smoke inhibition of expansion type flame-retarding particieboard
Effect is largely improved；Also has the effect of catalysis carbon-forming simultaneously.
It is an object of the invention to improve the flame retarding and smoke suppressing properties of existing fire-resistant-chipboard, provide a kind of fire-retardant better than tradition
The expansion type flame-retarding particieboard of the suppression cigarette of particieboard.
The purpose of the present invention can be achieved through the following technical solutions:
The component and content of the fireproof coating:
Wood shavings (60%), adhesive (6%-15%) polyphosphoric acid amine (5-10%), pentaerythrite (2-5%), melamine
(2-5%), auxiliary agent (1-3.5%), smoke suppressant (2-5%), curing agent (1%).
Wood shavings of the present invention are bamboo and woods fiber wood shavings, one of wooden shavings such as Aspen wood shavings or several mixtures.
Smoke suppressant of the present invention is that manganese chloride, copper chloride, iron chloride is one such or several mixtures.
Auxiliary agent of the present invention includes into dispersing agent, diluent, defoaming agent.
Adhesive of the present invention is Lauxite of the solid content in 50%-60%.The invention the following steps are included:
(1) it matches and stocks up according to following components: wood shavings (60%), adhesive (6%-15%) polyphosphoric acid amine (5-10%),
Pentaerythrite (2-5%), melamine (2-5%), auxiliary agent (1-3.5%), smoke suppressant (2-5%), curing agent (1%).
(2) by adhesive, fire proofing additive, the mixing such as curing agent is put into stirring instrument and stirs at low speed, is uniformly mixed it,
Then mixture and wood shavings are mixed and are put into that stirrer for mixing is uniform, next puts it into assembly in mold, finally by base and
Finger gauge is put into hot press, 150 DEG C -180 DEG C at a temperature of hot pressing 6-10 minutes, just prepared a kind of expansion type flame-retarding plane
Card.
Advantages of the present invention:
Wood shavings used in the present invention derive from residue, from a wealth of sources and protection forest resourceies.
Smoke suppressant used in the present invention can effectively reduce smoke amount, while being produced by thermal decomposition in combustion process
Raw hydrogen chloride, catalysis carbon-forming improve charring layer intensity, have completely cut off the conduction of heat, extended the resistance to combustion time.
