Description
Technical field
The present invention relates to fiber-like board technology field, specifically refer to a kind of production method with the plant multifilament modification plate of air purification function.
Background technology
The develop rapidly of adjoint domestic real estate market and upholstery, the fiberboard industry as stock emerges rapidly, and within 2014, China's fiberboard total output is 6923.83 ten thousand steres, and the total market size is huge.Fiber-like sheet material in the market has two kinds, and a kind of is that single sheet material is spliced, as plank or bamboo chip by gluing.Another kind is traditional fiberboard (having another name called density board), by the raw material of unlike material, become granule by mechanical crushing, after applying Lauxite or other gluing preparations be suitable for, temperature-pressure is made, and it is divided into low density fiberboard (to be less than 0.65g/cm by density
3), medium density fibre board (MDF) is (between 0.65-0.80g/cm
3) and high density fiberboard (be greater than 0.80g/cm
3).Splicing sheet material not only forest tree resource consumption is large, and plate property is single, quality is firmly crisp, narrow application range; Though and traditional fiberboard has the advantages such as uniform in material, in length and breadth intensity difference are little, not easy to crack, but also there is more shortcoming simultaneously: 1, pulverize temperature-pressure gluing technique not easily moulding, make fiberboard moulding single; 2, traditional fibre plate quality is single and firmly crisp, without flexibility; 3, traditional fibre plate thickness and density are all comparatively large, more thick and heavy; 4, to yield poorly and resource consumption is large; 5, bonding glue contains harmful ingredients formaldehyde etc. more, not environmentally; 6, traditional fibre plate function singleness.Just because of traditional fibre plate exists above-mentioned many defects production capacity surplus in addition, therefore high medium density fibre board (MDF) project is classified as restricted construction project by National Development and Reform Committee.
Summary of the invention
The present invention is directed to many defects that traditional fibre plate exists, a kind of brand-new plant multifilament modification plate is provided.
For achieving the above object, the technical solution used in the present invention is as follows:
There is a production method for the plant multifilament modification plate of air purification function, comprise the steps:
Step one: all kinds of selected plant material is pulverized immersion respectively, and string is extracted in thread rolling;
Step 2: by extracted all kinds of strings in proportion mixing and water adding make anion slurry and stir, modified cationic starch is added in whipping process, combined the various plants fiber ordered arrangement making to dissociate by zwitterion, be finally modulated into the mixed plant fibre stuff of desired concn;
Step 3: the felt upper surface obtained mixed plant fibre stuff evenly being flowed into transmission, and partial dehydration is carried out to the mixed plant fibre stuff of felt upper surface, make mixed plant fibre stuff form wet fiber plate at felt upper surface;
Step 4: at the solution of wet fiber plate surface spraying containing Nano titanium dioxide, makes it to form purification membrane at fibreboard surface;
Step 5: adopt the wet fiber plate of pair roller to felt surface to carry out pressurization coiling, wet fiber plate is made to depart from felt and be incorporated into upper roller periphery by coiling is stacked, stacked reach desired thickness after cut off coiling, the wet fiber plate of upper roller periphery is departed from, the wet fiber plate of obtained desired thickness;
Step 6: obtained wet fiber plate is dry.
Further, between step 4 and five, also comprise the steps: to adopt mould moulding to wet fiber plate.
A kind of method for optimizing, in step 4, the thickness of purification membrane is 50-100 nanometer.
A kind of method for optimizing, the concrete grammar of step 2 is: add water after first being mixed in proportion by all kinds of string and make the anion slurry that concentration is 5%, be stirred to evenly, add the modified cationic starch accounting for mixed plant fibre weight 0.1%-5% again, be stirred to zwitterion fully to combine, finally adding water to stir is modulated into the mixed plant fibre stuff that concentration is 1.5%.
A kind of method for optimizing, in step 3, the method of the mixed plant fibre stuff of felt upper surface being carried out to partial dehydration is: the moisture first siphoning away 50%-60% mixed plant fibre stuff with negative pressure water sucting mode from felt bottom surface, make mixed plant fibre stuff form moisture fiberboard at felt upper surface, then through roller extruding make the fiberboard on felt dewater to water content be 30%-40%.
A kind of method for optimizing, the concrete grammar of step one is: all kinds of plant material is ground into the particle that particle diameter is 5-50mm, is to soak 24-72 hour in the basic solvent of 10-14 in pH value, then by kneading or grinding leaser dissociation sub-wire, extracts string.
A kind of method for optimizing, the concrete grammar of step 5 is: be leave standstill 6-24 hour in the environment of 1%-2% in air humidity by wet fiber plate, make it dry in air exchange mode.
Further, after step 5, then surface treatment is carried out to fiberboard.
A kind of method for optimizing, in step 3, the transmission speed of felt is 90-100m/min.
A kind of method for optimizing, in step 4, the upper roller girth of coiling is 1000-5000mm.
The beneficial effect of the technical program is: 1, Nano titanium dioxide can formaldehyde under illumination condition, the harmful substance oxidation Decomposition such as toluene become carbon dioxide, water and organic acid, after being sprayed at fibreboard surface formation purification membrane, fiberboard is made to have air purification function, owing to being spray before coiling, therefore obtained modified fibre intralamellar part is folded with multilayer purification membrane, and its clean-up effect is for many years sustainable; 2, before fiberboard drying, by mold pressing, any moulding is carried out to wet fiber plate, or by roller, wet fiber plate surface modes is gone out decorative pattern, enriched fiberboard form, extended purposes; 3, can be made into the sheet material of different hardness by adjusting the mixed proportion of various fiber, even soft sheet material can doubling and do not change its performance, and compare firmly crisp traditional fibre plate, its accommodation is wider; 4, the sheet material of different densities is can be made into by adjustment coiling pressure, and by control flow check slurry amount and the coiling number of plies, can be made into the sheet material of 0.5-300mm different-thickness, not only sheet material quality range of choices is wider, and compare thick and heavy tradition as decoration of exterior wall fiberboard, low-density and frivolous sheet material safety and reliability; 5, owing to being uninterruptedly shaping, by regulating the adjustable production capacity of felt transmission speed, be more than ten times of traditional fibre plate production capacity, institute adopts raw material range of choices extensively, is generally obsolete material, effectively economizes on resources; 6, different string is by Hydrogenbond, formaldehydeless component glues, environmental protection.
