Abstract
The invention discloses a plant fiber composite with plant fiber as a main raw material and other chemical materials as auxiliary materials. The plant fiber composite comprises, in percentage by mass, 45%-47% of plant fiber, 35%-44% of resin glue, 3.5%-5% of a curing agent and 3%-7% of alcohol, wherein the plant fiber contains, in percentage by mass, 88%-94% of wood wool powder. The plant fiber composite has high density and anti-compression strength, the water absorption rate is lower than 2.4%, the insulation performance is good, and the plant fiber composite cannot be broken down under voltage of 15,000 volts in 1 minutes, does not deform or age, is corrosion-resistant and is an ideal material for manufacturing of furniture, building decorations, artware and the like.
Description
The present invention relates to a kind of matrix material, particularly a kind of is main raw material with vegetable fibre, the composite material of plant fiber obtained for subsidiary material with other industrial chemicals.
At present, prior art related to the present invention is as notification number Chinese patent disclosed in CN1051008A, name is called " plastic waste and composite material of plant fiber ", it be with a large amount of vegetable fibre particularly wood chip for filler, with used heat thermoplastic plastic for binding agent, through the matrix material of certain process combining, although it is low that this matrix material has cost, plasticity-is strong, the advantages such as good toughness, but be take plastics as binding agent due to it, thus the matrix material obtained is made to exist easily aging, deflection is large, vary with temperature shortcomings such as easily becoming fragile, and general plastics all contain toxic substance.In addition, with vegetable fibre be the main matrix material made also as fiberboard, the plant fiber particle footpath that fiberboard is selected is larger, generally in 8 ~ 20 orders, in proportioning, the ratio of synthetical glue is lower, usual employing 20 ~ 24%, and manufacture craft upward pressure and temperature all lower, so the weak point of fiberboard to be intensity low, water-intake rate is high, corrosion-resistant, and after making moist, resistivity changes greatly, density is low.
The object of this invention is to provide a kind of intensity, density is high, corrosion-resistant good with crushing resistance, not yielding aging composite material of plant fiber.
The object of the invention is to be realized by following technical scheme, composite material of plant fiber is by (quality %): 45 ~ 47 vegetable fibres, 35 ~ 44 Resin adhesives, 3.5 ~ 5 solidifying agent and 3 ~ 7 alcohol composition.In said ratio, wood down powder can be selected in vegetable fibre to be main raw material, it can account for 88 ~ 94% of vegetable fibre proportioning, other vegetable fibre is as auxiliary material, because the cost compare of wood down powder is low, it is the recycling of waste material, wood down powder can be considered to be worth doing by redwood, whitewood considers to be worth doing, weed tree sawdust obtains through grinding and processing, other vegetable fibre can be reed, cotton stalk, wheat straw etc., wood down powder and other vegetable fibre all need first flour before batching, vegetable particle footpath is made to be 180 ~ 200, order can ensure the density of material and the bright and clean of product surface like this, what binding agent of the present invention adopted is Resin adhesive, it serves firmly cohesive action to vegetable fibre powder, and hot compacting at the temperature of the pressure of 350 ~ 400kg/cm2 and 180 ~ 220 DEG C, Resin adhesive is made fully to permeate surface in vegetable fibre, rapid solidification, improve intensity and the density of material, Resin adhesive will first be dissolved by alcohol before use, and then and vegetable fibre, solidifying agent fully stirs together, make it Homogeneous phase mixing, the effect of solidifying agent is the Quick-forming impelling material further.The present invention is adding man-hour, can add different pigment as required, and make imitative redwood, antique copper, parian material, various furniture is made in mold pressing, builds decoration, workmanship, household electrical appliances auxiliary equipment etc.
The present invention compared with prior art, crosses 180 ~ 200 order wood suede plant fiber materials owing to having selected, selects highdensity Resin adhesive to be binding agent simultaneously, make the density of matrix material reach 1.4 ~ 1.6g/cm3, be doubled many than vegetable fiberboard; Ultimate compression strength is 226MPd, improves nearly twice than vegetable fiberboard, and hardness is HB234, and water-intake rate, below 2.4%, has been reduced to 15 times than fiberboard.In addition, the matrix material that the present invention makes, good insulation preformance, can within 1 minute, not puncture by proof voltage 1.5 ten thousand volts, dielectric strength is 6.67MV/M; Undeformable and indehiscent, also not easily aging, not by influence of temperature change, and good corrosion resistance, nontoxicity.
Below for 100kg batching, different proportionings is selected to be described in further detail the present invention.
Embodiment 1, select vegetable fibre 45kg, wherein weed tree sawdust powder 39.6kg, cotton stalk fiber 4.9kg, 2127 Phenol aldehyde resin 44kg, wake up powder 4.5kg, alcohol 5.5kg, technological process are such, first vegetable fibre and weed tree sawdust powder and cotton stalk fiber uniform mixing, be then be crushed to regulation fineness in 180 ~ 200 object hammer crushers in fineness regulation scope.By 2127 Phenol aldehyde resins alcohol mixed dissolution, then the Resin adhesive after vegetable fibre, dissolving, powder of waking up are mixed and stirred together, mix and stir in process at above-mentioned material, the pigment after dissolving can be added as required, mix and stir 70 minutes to 85 minutes, make pigment, vegetable fibre, Resin adhesive, wake up powder reach uniformity.After mixing, take out and dry, the water ratio after oven dry reaches 9 ~ 11%, can sealed storage be packed stand-by, when needing to make product, mold pressing will be carried out again, mixture is put into desired product shaped mold, hot pressurize 25 ~ 35 seconds on oil press, die temperature is 185 ~ 195 DEG C; Pressure is 350 ~ 400kg/cm2, also will exit 2 ~ 3 times in hot pressing, and each interval time is 30 seconds to 40 seconds, moisture content in material is fully vapored away, and then pressurize is taken out for 2 ~ 3 minutes, removes product burr, overlap, correction, polishing, makes product unanimously bright and clean.
Embodiment 2, gets red wood dust 44.1kg, and reed fiber 4.9kg, 2127 Phenol aldehyde resin 41kg, powder 4.5kg, alcohol 5.5kg, the technological process of waking up are identical with embodiment 1.
Embodiment 3, gets white wood dust 44kg, wheat straw fiber 5kg, 2127 Phenol aldehyde resin 39kg, powder 4kg, alcohol 4kg, the technological process of waking up is identical with embodiment 1.
Embodiment 4, gets weed tree sawdust powder 51.3kg, and wheat straw fiber 5.7kg, 2127 Phenol aldehyde resin 35kg, powder 4.5kg, alcohol 3.5kg, the technological process of waking up are identical with embodiment 1.
