Abstract

The invention discloses novel high-imitation flame-retardant wood. The novel high-imitation flame-retardant wood is prepared from bamboo, nano-aluminium oxide, ammonium polyphosphate and composite boron modified phenolic resin. The novel high-imitation flame-retardant wood is prepared by the steps of 1) grinding fresh bamboo to remove bamboo green on the surface, slicing to removing tabasheer at the part close to the center; 2) feeding the dried slices into a pressure tank, and carbonizing for 30 to 180min; 3) adding aluminium oxide and ammonium polyphosphate to the carbonized slices, agitating, and then adding boron modified phenolic resin; 4) positioning the slices processed in step 3), and then performing hot press for 10 to 40min to obtain the high-imitation flame-retardant wood. The high-imitation flame-retardant wood is able to perfectly replace solid wood, has effective flame-retardant performance and is high in safety.

Description

Novel height imitates fire retarding wood

Technical field

The present invention relates to a kind of fire proofing, particularly relate to a kind of novel height for alternative solid wood and imitate fire retarding wood.

Background technology

In recent years, along with the raising of material and culture level and the change of people's aesthetic conceptions, nowadays along with solid wood furniture more and more treasures parent, but solid wood furniture, solid wood products etc. but had following defect:

1, timber resources is more and more tighter, the enforcement of domestic natural conservation project, after forest zone is prohibited and is cut down, limits and cut down, and the minimizing of limit world forest resources, high-quality log is day by day in short supply, and natural timber output sharply declines; Thus cause the price of solid wood furniture, solid wood products more and more higher.

2, security against fire, along with greatly developing of China's economic construction, the primary timber of a large amount of use makees furniture or decorates under construction, except stay insect pest, go rotten, yielding except, leave fire disaster hidden danger, meet fire time flammable, inflammable, ignite, combustion-supporting during fire, leaving difficulty to fire extinguishing, is also that fire incident is sent out, and causes the reason of the dead group's wound of fire group.

Summary of the invention

For prior art above shortcomings, the object of the present invention is to provide a kind of novel height to imitate fire retarding wood, perfectly can replace solid wood material, thus make furniture, wood-based product's cost lower, and can be effectively fire-retardant, security is higher.

In order to solve the problems of the technologies described above, the technical solution used in the present invention is such: a kind of novel height imitates fire retarding wood, it is characterized in that: comprise bamboo, nano-aluminium oxide, polyphosphoric acid amine, compound boron modified phenolic resin, obtain as follows:

1) method of fresh bamboo polishing is removed surperficial surf green, hack and remove the tabasheer near central part, making bamboo chip thickness 0.2-0.4mm, then bamboo chip is dried;

2) bamboo chip after step 1) being dried loads pressurized tank, heats 60 DEG C to 250 DEG C, pressurization 1.0-2.5MPa, carbonization 30 minutes to 180 minutes;

3), in the bamboo chip after the carbonization of 25-150 part, add 1-50 part nanoscale alundum (Al2O3) and 1-20 part polyphosphoric acid amine, after stirring, add 50-100 part boron modified phenolic resin;

4) bamboo chip after step 3) process is inserted mould, under the condition of pressure 120t-250t, temperature 30 DEG C-120 DEG C, hot pressing 10-40 divides kind, obtains high imitative fire retarding wood.

Further, in step 3), add 20-60 part fiber.

Further, described fiber is straw fiber or fruit tree branch fiber.

Compared with prior art, tool of the present invention has the following advantages:

1, undertaken being processed to form imitated wood material by bamboo, with low cost, and save a large amount of precious primary timber, be conducive to protecting forest resources and environment, for the consideration of environmental protection and enterprise development, solid wood substitute certainly has better development prospect.

2, have very excellent fire resistance, water proofing property, alternative all primary producing wood furnitures, energy-saving and environmental protection solve a difficult problem for timber natural deformation and cracking simultaneously; Fire protecting performance reaches national combustibility A1 grade standard; Thus public building fire-protection rating can be improved, reduce fire incident.

3, can saw, can mortise, can nail, more conveniently to process, easy to use.

Detailed description of the invention

1) method of fresh bamboo polishing is removed surperficial surf green, hack and remove the tabasheer near central part, making bamboo chip thickness 0.2-0.4mm, then bamboo chip is dried;

2) bamboo chip after step 1) being dried loads pressurized tank, heats 60 DEG C to 250 DEG C, pressurization 1.0-2.5MPa, carbonization 30 minutes to 180 minutes;

3), in the bamboo chip after the carbonization of 25-150 part, add 1-50 part nanoscale alundum (Al2O3) and 1-20 part polyphosphoric acid amine, after stirring, add 50-100 part boron modified phenolic resin;

4) bamboo chip after step 3) process is inserted mould, under the condition of pressure 120t-250t, temperature 30 DEG C-120 DEG C, hot pressing 10-40 divides kind, obtains high imitative fire retarding wood.

During concrete enforcement, 20-60 part fiber can be added in step 3); Described fiber is straw fiber or fruit tree branch fiber; Make appearance better.

As a kind of embodiment, its making step is as follows:

1) method of fresh bamboo polishing is removed surperficial surf green, hack and remove the tabasheer near central part, making bamboo chip thickness 0.3mm, then bamboo chip is dried;
