Abstract
The invented product uses saw-dust and glass fibre as main components, resin and inorganic cementing material as binder and adds a little amount of additives, which are mixed thoroughly in accordance with proportion, then poured in mould. Through solidifying, demoulding and curing etc. technological process the product is made up. Said product is approximate to the natural timber in physical properties and working properties and overcomes the sortage of moisture absorbing of the same kind products. The water resistance property is raised. It features large strength, good nature for nailing, sawing and planing and high productive efficiency.
Description
The present invention relates to a kind of synthetic wood and manufacture method thereof that can replace natural timber to use.
Along with the continuous development of economic construction, every profession and trade more increased the demand day of timber, and the in short supply of timber resources caused crisis to the mankind.Thus, the kinds of artificial synthetic wood has been proposed at present to replace the method for natural timber.For example: number of patent application: " 90105150.0 " name is called " composite magnesian fibre board and manufacture method ", it mainly is composited with magnesium gelatinous material is bonding by multi-layer fiber matter cloth, magnesium gelatinous material is to be formed by magnesia, magnesium chloride, talcum powder, filament and water modulation, though its product that makes is better than glued board and fiberboard to a certain extent, but the existence of free halogen (magnesium chloride) in its magnesia cementing material, the defective that causes its moisture absorption, thus be restricted when using.And because it adopts simple cement inorganic material is bond, though its intensity is big, its weight is relatively also big, and it eats nail performance, plane, saw performance relative mistake.
Aim of the present invention is to propose a kind of its physical property and all approaching with the natural timber synthetic wood of processing characteristics, and make it have excellent waterproof, fire-retardant, moistureproof, anti-corrosion performance, and need not pressurize in the manufacturing, heat, three-dimensional moulding by casting amount is big, is easy to form suitability for industrialized production.
For finishing the purpose of foregoing invention, technical scheme of the present invention has been proposed on the repetition test ground foundation.The present invention is a main component with sawdust, glass fibre, is bond with resin, cement inorganic material, and adding works the additive of strengthening the property to cement inorganic material and resin.
Cement inorganic material of the present invention is portland cement, alumina cement, sulphate aluminium cement, magnesia cementing material, gypsum etc.
Resin of the present invention is a Lauxite.
Additive of the present invention is trifling dose an of ammonium chloride, disodium hydrogen phosphate, RSF cement.
Sawdust consumption (weight ratio) as main component is that 15-29%, glass fibre are in the present invention: 1-5%, inorganic salts cementing material are: 64-80%, resin are: 1-5%, additive trace.
The concrete consumption of additive can be among the present invention: ammonium chloride be amount of resin 2%, tertiary sodium phosphate is that the 4-7 ‰ of cement inorganic material, 0.3-1 ‰, the little injecting of RSF cement that prodan is cement inorganic material are the 0.5-1.5 ‰ of cement inorganic material, adds warm water (40-60 ℃) after above-mentioned component is mixed in proportion with being prepared into solution at 1: 10.
Manufacture method of the present invention: after sawdust, cement inorganic material mixed in proportion, adding water stirs, add again after resin and additive solution fully stir, add and be poured into die for molding after glass fibre continues to stir, through solidify, demoulding maintaining process is processed into.
Employed mould adopts more smooth material to make in the manufacture method of the present invention, it is made up of side plate, base plate, dividing plate and caulking groove, biside plate is hinged with the two ends of base plate respectively, side plate is provided with a plurality of caulking grooves, thereby is used to make dividing plate to insert the mould that constitutes a plurality of synthetic woods of moulding simultaneously.This mould also can be designed to different shapes as required.
The present invention is owing to adopt resinoid bond, thereby controlled the activity of free halogen in the inorganic glue material effectively, overcome its moisture absorption, improved its water-resistance, and adopt cement inorganic material and resin-bonded to use, its synthetic wood weight is adjustable, and all can reach quality requirement, and have intensity big, eat nail, hold nail, saw, plane be functional, because its method for manufacturing adopts casting, its work efficiency can improve more than 5 times with the like product ratio, and wood surface is smooth smooth, and pourable special-shaped timber.The prepared timber of the present invention can replace natural timber, be widely used in high-grade furniture and make, building trade etc., and in the manufacturing process three-waste free pollution environment.
The embodiment that the present invention provides will further describe composition of the present invention and manufacture method:
The accompanying drawing that the present invention provides is the mould structure schematic diagram.
Embodiment:
In the component of the present invention; sawdust adopts the offal of band saw processing; require not water content; do not have block sawdust and cross that its use amount (weight ratio) is 22% behind 9 mesh sieves; magnesia glued cement is 72.6% to pour into to do in the batch mixer and mixed 10-15 minute; add the water wet mixing and shut down adding 301 modified urea-formaldehyde resins 3.2% to the material during no lump; the trace mineral supplement aqueous solution continues to stir 8-10 minute; the ripe glass fibre 1.2% that adds length again and be 25mm continues to stir 5 minutes; then compound is poured into equably moulding in a plurality of dividing plates in the mould; this mould (as shown in the figure) adopts and makes than lubricious material; as glassware; it is by side plate 1; base plate 2; dividing plate 3; caulking groove 4 constitutes; biside plate 1 is hinged on the two ends of base plate 2 respectively; side plate 2 is provided with a plurality of caulking grooves 4; thereby be used to make dividing plate 3 to insert the mould that constitutes a plurality of synthetic woods of moulding simultaneously; its mould also can be designed to different shapes as required; in cast, be placed with bobbing machine in the bottom of mould; purpose is that the compound of cast is filled evenly; its bobbing machine can adopt the microwave vibrations bed; after treating that die casting is full; stop vibration; the unnecessary material in mould top is scraped off compound with rubber flap to be needed to solidify 6-8 hour in mould; mould takes off maintenance then; with the timber folding and unfolding that makes on smooth foundation stone; can laminate successively; but can not be above 1.2 meters; its demoulding maintenance needs 5-7 days; solidifying; demoulding maintenance therebetween; require indoor airtight; stuffy; humidity remains on the 40-60 degree, and room temperature remains on 15-25 ℃.The concrete consumption of additive of the present invention is: magnesium chloride is 0.06%, tertiary sodium phosphate is: 0.04%, prodan is: 0.004%, RSF cement foaming agent is: 0.004%, additive add fashionable need be prepared into solution by 1: 10 with warm water (40-60 ℃) after adding again.
