Abstract
The invention relates to a high strength fiber board which comprises 90-95 portions of paper pulp by weight and 5 to 10 portions of adhesive by weight. When the paper pulp which is raw paper pulp or deinked wastepaper paper pulp is taken as a raw material, a board body shows a maple color, and the density of the high strength fiber board is 1.3 to 1.5g/cm3. When the thickness of the high strengthfiber board is 3mm, the static bening intensity of the high strength fiber board is 85 to 95MPa, the elasticity modulus of the high strength fiber board is 15000 to 17000MPa, and the inner bonding strength of the high strength fiber board is 2 to 5MPa. The production of the high strength fiber board comprises the following eight steps of: the pulping and the deinking of the paper pulp, squeezing for dehydration, gum dipping, squeezing for degumming, drying or refrigeration, crushing, mat formation and hot pressing. The high strength fiber board made according to the method has the advantages of single raw material, convenient collection, low cost, high strength of manufactured boards, and is especially suitable for being used as decorative boards and bottom boards on the high-level vehicles.
Description
Technical field
The present invention relates to a kind of beaverboard preparation, is the method with paper pulp and organic adhesion agent producd fibers plate specifically.
Background technology
CN101209568 discloses the technology in Lu Hongying's the patent application of " light fiberboard and preparation method thereof "; it is a kind of follow-on wet-process fiber board production method; cut into slices through boiling or defibrator process with timber; homocline slurrying; the slab moulding; second dehydration; drying and shaping; stopping off; sand milling is fixed thick; operations such as the packing of cutting edge are made; except that adhesive; also add the polyacrylamide flocculant; aluminum sulfate; paraffin; polyvinyl alcohol; brightening agent; the high-intensity fiber element; raw material is numerous; production cost is higher; and the intensity of the unexposed product of this application and density, have no way of investigating the height of its intensity and the weight of quality.CN1172199 discloses Cheng Yongcun's " light-high-strength combined wall board " patent application technology, be to make surface layer with the lightweight dressing board of levels, make the bonding composite plate that forms of sandwich layer with mineral wool board, rock cotton board, expanded pearlite plate, superfine fibre plate or ceramic cotton plate, make materials for wall, this plate light weight, but must have bigger thickness just can reach certain intensity, otherwise insufficient strength height.
Summary of the invention
At the above-mentioned deficiency of prior art, task of the present invention is to design a kind ofly to do in vehicle floor or automobile, train, steamer, the aircraft railway carriage or compartment or the usefulness pure pulp of cabin inner trim panels and high strength fiberboard and the production method thereof that adhesive is raw material.
The concrete technical scheme of finishing above-mentioned task is: this high strength fiberboard, under the over dry state, form by the adhesive of 90-95 portions of paper pulp by weight and 5-10 weight portion; When paper pulp is former paper pulp or the old paper stock after deinking when being raw material, plate body is light brown, density 1.3-1.5g/cm
3When plate thickness was 3mm, its MOR was that 85-95MPa, elastic modelling quantity are 15000-17000MPa, internal bond strength 2-5MPa.
This high strength fibre plate producing process comprises the following steps:
(1) making beating of paper pulp and deinking: with former paper pulp is that wood pulp is pulled an oar into micron-sized fiber pulp through beater, or with writing the waste paper that leaves ink marks, carries out as required pulling an oar into micron order fiber pulp (the following paper pulp that still is referred to as) after deinking is handled;
(2) press to squeeze dehydration: the paper pulp after step (1) is handled with squeeze, roll compacting, extrusion dewaters to moisture content 30%-40%;
(3) impregnation: selecting for use and being coated with 4 glasss of viscosity is 15-20S, the phenol glue of solid content 40%-50%, the weight ratio of pressing water and glue during use is (0.5-1): 1 dilution, drop into impregnation in the glue with the micron order fiber pulp after the dehydration, immerse back stirring 1min and pull out, enter next procedure;
(4) press to squeeze and to come unstuck: the solid content by glue is 100%, press squeeze come unstuck to resin added be 5%-10%;
(5) dry or freezing: being dried to moisture content under the 45-55 ℃ of temperature is 6%10%, or presses the navel back of coming unstuck and directly drop into and freeze that the chamber is freezing build-ups ice;
(6) pulverize: the pulverizer with being with cooling device of drying is broken into micron order with dried pulp powder, then separates fiber and mixes with glue particulate, water particulate and be velveteen shape thing, through the freezing micron order that directly is ground into;
(7) mat formation: crushed material pipeline system on forming belt is mated formation, just be pressed into and dredge the scutum base, cut off into piece by back plate sizes, block-by-block places on the backing plate;
(8) hot pressing: adopt the hot pressing of single or multiple lift press, temperature 150-200 ℃, pressure 2-6MPa, hot pressing 2-15min.
The invention has the beneficial effects as follows that this product only needs two kinds of raw materials, the collection raw material is convenient, cost is low, technology is simple, the timber intensity height of making.
The specific embodiment
The present invention below is listed in the table below interval values such as the temperature of the thinner ratio of solid content, glue and the water of the moisture content of proportion of raw materials, dehydration, glue, resin added, dried moisture content, hot pressing and pressure, is combined into five embodiment and is illustrated.
Embodiment 1 (embodiment 1 projects numerical value in the table of comparisons): the standby former wood pulp of 90 weight portions that is equivalent under the over dry state is former paper pulp or old paper stock and the 5 weight portion phenol glues handled through deinking, paper pulp is dropped in the water, break into the micron-sized fiber pulp of separating with beater, drag for to calender roll compacting dewater to moisture content be 30%, drop into water-cement ratio and be impregnation in 0.5: 1 the phenol glue glue pond, selecting for use and being coated with 4 glasss of viscosity is 15S, the phenol glue of solid content 40%, pick up after stirring 1min, press to squeeze again that to come unstuck to being equivalent to resin added be 5%, carry out being dried to moisture content 6% under the 45-55 ℃ of temperature, in having the pulverizer of cooling device, be ground into micron-sized velveteen shape thing again, or directly drop into and be ground into micron order crushed material pipeline system on forming belt immediately after freezing that the chamber is freezing and freezing and mat formation, the thickness of slab that the thickness of shop material is pressed into is that the amount of 3mm is laid, be pressed into slab with roll-in or plate, this slab
Matter is dredged, and is convenient to cut off into piece, cuts off into piece by back plate sizes, and block-by-block places backing plate, and with multidaylight press hot pressing 2min under 150 ℃ and the 2MPa pressure, the cooling back is taken out and carried out postprocessing working procedures such as veneer or embossing, sanding, side cut, check, packing again.In the hot pressing process, temperature, the time of the thickness effect hot pressing of plate, the size of the density decision pressure of plate during operation, should be made accommodation by different situations, and this colleague knows, and does not carefully state.
All the other embodiment 2-5 make this fiberboard all by the pairing numerical value of each respective item with embodiment 1 same procedure in the table.Wherein preferred with embodiment 1-3, do not use as panel or the veneer of still needing handles, be the cost-saving, can not deinking.Be similarly the urea-formaldehyde glue of thermosetting cement, cyanurotriamide modified glue also can be used for the present invention, can produce precipitation but place certain hours because of these two kinds of glue, therefore should face to join and face usefulness, uses up after joining, should also be noted that to change corresponding hot pressing temperature, time control range.
