Description
Technical field
The invention belongs to floor processing technique field, more particularly to a kind of no aldehyde antiflaming floor and its manufacturing method.
Background technology
At present, wood floors recovered one's original simplicity with it, the natural decorated style of texture, monopolize floor decorative material huge legendary turtle always
Head, but since the problems such as product price is high, burst size of methanal is high and flame retardant property is not high constrains the development of Floor Industry.
Now, development agricultural circular economy is of great significance to China's the Implement of sustainable development strategy, according to statistics, the annual agricultural in China
Discarded object is more than 1,700,000,000 tons, including agricultural crop straw, wood machining residues etc..Therefore, agricultural industrial wood waste (such as straw are utilized
Stalk, wood powder etc.) to prepare floor be research topic that wood working industry is concerned.Stalk floor is according to conventional wood glue
Stick, intensity is not high and environmental-protecting performance is poor, therefore is mostly considerably increased and be produced into using expensive isocyanate adhesive
This；Wood powder class discarded object is made generally in wood moulding class floor, has many advantages, such as waterproof, moisture-proof, corrosion-resistant, but there are quality it is more crisp,
The shortcomings of toughness is inadequate.In addition, the floor flame retardant property that now prepared by agricultural industrial wood waste is low, there are certain safety is hidden
Suffer from.
The content of the invention
To solve the above problems, the present invention provides a kind of no aldehyde antiflaming floor and preparation method thereof, it is surplus with timber processing
Excess and crop residue stalk are packing material, by compounding skill with magnesium chloride, cooperateing with for magnesia inorganic coagulation material
Art is prepared, and product is light high-strength, has many advantages, such as environmentally friendly, fire-retardant.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of preparation method of no aldehyde antiflaming floor, its preparation method comprise the following steps：
(1) forage is prepared：By timber, crops stalk crushing, timber, the crops powder of certain specification are screened, is done
After dry, it is mixed in a certain ratio；
(2) it is magnesium chloride, coagulant, magnesia and filler is soluble in water, form inorganic bond agent solution；By step (1)
Obtained forage is dissolved in above-mentioned inorganic bond agent solution, stirs evenly, and forms mixed liquor；

cm2, veneer condition：110~130 DEG C, 0.5~0.8MPa of hot pressing pressure, 5~10min of hot pressing time of hot pressing temperature.
Wherein, the molecular weight of polyethylene glycol is 600~1000, has good heat, acid, alkaline stability, lubricity and glues
Knot property, form is solid-state like for half liquid, and hygroscopicity is relatively low, and intramolecular has hydroxyl polar group, there is certain dissolubility in water,
Since timber, crop branch fiber contain abundant hydroxyl polar group, and there is good compatibility, poly- second two with them
Alcohol can improve inorganic binder and timber, the uniformity that mixes of agricultural crop straw, secondly as the good bonding of polyethylene glycol
Have between property and its metallic element for containing abundant hydroxyl polar group and chlorine oxygen magnesium with timber, crop branch fiber compared with
Good intermolecular force can improve the mechanical strength on floor.
The present invention also provides the above method prepare without aldehyde antiflaming floor.
The advantageous effect that the present invention obtains is：
(1) present invention is using forest and agricultural biomass as raw material, the manufactured no fire-retardant magnesia oxychloride cement base plate of aldehyde, more woodenly
Plate is compared, and possesses no aldehyde environmental protection, excellent fireproof performance, the features such as mechanical strength is good, surface abrasion resistance is high, resistant to chemical etching,
Indoor heat losses can be also reduced simultaneously, possess heat preservation energy-saving function；
(2) present invention by adding flyash, silicon powder filled up the stomata ruler footpath in inorganic coagulation material, avoid floor
Material generates microgroove and further expands craze and transfiguration, improves the mechanical strength on floor；
(3) present invention accelerates magnesia oxychloride cement hydration process, effectively protects by adding coagulant, early strength agent collective effect
The mechanical strength of its early anaphase higher level is demonstrate,proved, improves production efficiency；The fiberglass gridding cloth that alternating is mated formation, can maintain for a long time
The good mechanical property in floor improves the durability on floor.
