Description
Technical field
The invention belongs to particieboard technical fields, and in particular to a kind of preparation method of stalk-shaving board.
Background technique
Agricultural crop straw is a kind of renewable resource of preciousness, due to the shadow by factors such as consumption idea and life styles
Ring, for a long time, stalk resource be in high consumption, high pollution, low output situation, considerable a part of agricultural crop straw quilt
It throws aside or burns, do not developed and used reasonably.In recent years to agricultural crop straw（Rice, wheat, soybean, cotton, flax
Equal agricultural crop straws）The research of comprehensive utilization is paid more and more attention, and is suppressed after stalk to be carried out to the industrial treatment of a series of complex
One of research direction is important at plate.
In the prior art, using agricultural crop straw as the stalk-shaving board that part raw material manufacture started be applied to furniture,
The fields such as packaging, therefore, expanding agricultural crop straw as the use scale of particieboard raw material is to realize stalk resource circulation benefit
One of effective way.But the fire protecting performance of existing stalk-shaving board is not high, simultaneously as agricultural crop straw surface
There are waxy substances, so that binder is difficult to infiltrate stalk, can not react to form chemical bond generation anchor with stalk internal hydroxyl groups
Effect, causes the stalk-shaving board glue performance poor.
Summary of the invention
The technical problems to be solved by the invention：For the low problem of current stalk-shaving board fire protecting performance, the present invention is mentioned
For a kind of preparation method of stalk-shaving board.
In order to solve the above technical problems, the present invention is using technical solution as described below：
A kind of preparation method of stalk-shaving board, the preparation method include the following steps：
（1）Stalk is taken to be crushed, by sieving particle and ethanol solution in mass ratio 6:4~9 are uniformly mixed, and it is quick-fried to carry out steam
It is broken, steam blasting object is collected, steam blasting object is filtered, collects filter residue, natural air drying collects air dry matter；
（2）By air dry matter, hydrogen peroxide in mass ratio 1:3 are uniformly mixed, and ultrasonic vibration adds oxidation promoter, additive, stirs
It mixes, is put into reactor, be warming up to 60~80 DEG C, stir 60~90min, add auxiliary agent, keep the temperature；
（3）It is cooling after heat preservation, material is collected out, according to parts by weight, takes 80~90 parts to go out material, 10~17 parts of glue
Glutinous agent, 3~6 parts of dispersing agents and 1~3 part of silicone acrylic emulsion, stir evenly, and collect stirring mixture
（4）Stirring mixture is put into mold, 10~15min of precompressed at 0.3~0.6MPa, then carries out hot pressing, hot pressing item
Part is 4~7MPa, and 168~172 DEG C, 7~9min obtains plate embryo, is cut, sanding is to get stalk-shaving board.
The step（1）Middle stalk is wheat stalk, corn stover, any one in rice straw.
The step（1）The condition of middle steam blasting is 2~4MPa, maintains 90~120s of pressure.
The step（2）Middle oxidation promoter is boric acid, acetic acid and nitric acid in mass ratio 6:4:3~5 mix, and aoxidize
The additive amount of auxiliary agent is the 10~15% of air dry matter quality.
The step（2）Middle additive is ethyl orthosilicate and cetyl trimethylammonium bromide in mass ratio 7:1~3,
And additive amount is the 13~17% of air dry matter quality.
The step（2）Middle auxiliary agent is vinyltriethoxysilane and aluminium oxide in mass ratio 4~7:3~5 mixing and
At, and the 12~14% of the additive amount air dry matter quality of auxiliary agent.
The step（3）Middle adhesive is urea-formaldehyde resin adhesive, solid content 58~60%, free formaldehyde mass fraction 0.
11~0.13%.
The step（3）Middle dispersing agent is magnesium stearate, any one in odium stearate.
The present invention is compared with other methods, and advantageous effects are：
The present invention carries out Steam explosion treatment to stalk first, can be carried out to structures such as fibers in stalk by steam blasting
It destroys, while also improving the porosity inside stalk, using hydrogen peroxide as oxidant to stalk inside progress oxidation processes, then with
Oxidation promoter is handled stalk inside as oxidation intercalator, and the ash content of stalk can be effectively reduced, increase stalk
Micro-expansibility energy has activated surface group, and the boric acid being added can effectively improve the fire protecting performance of stalk, will then add
Agent is mixed, and mixes ethyl orthosilicate adequately with stalk, make stalk internal void fill ethyl orthosilicate, then with
Cetyl trimethylammonium bromide is reacted as template and forms mesoporosity silica in stalk pore interior, effectively
The mechanical property and fire protecting performance of particieboard are improved, while the generation of pernicious gas can also be reduced, recycles three second of vinyl
Oxysilane is modified it, and the adhesiveness of base-material and adhesive is increased by the effect of vinyltriethoxysilane
Can, and pass through the absorption of internal porosity substance, adhesiveness is further improved, while the silicone acrylic emulsion being added can act on
Intermediate bridge is combined base-material and adhesive in the form of chemical bond, and the silicone acrylic emulsion being added improves stalk plane
The fire protecting performance of card.
