Abstract
An artificial composite board is made up of wooden fibres as skeleton material, inorganic adhesive as main body, and organic coupling agent. The optimal ratio of organic coupling agent to inorganic adhesive is 1:3.0-6.6. The optimal ratio of skeleton material to inorganic adhesive is 1:0.8-1.3. Said board features high strength, resisting fire and water, easy machining and low cost.
Description
The invention belongs to the manufacture field of similar wood material, more specifically say so about the forming technique of extraordinary wooden boards.
The wooden boards of present architectural use, a class are to be stock with sawdust or wood chip, use the organic resin binding agent, and laminate or glued board through lamination, gummed form are extensive use of.Without this sheet material of special treatment, its waterproof fireproofing poor-performing, its cost is higher comparatively speaking.Another kind of is to be the inorganic plate that binding material is made with the inorganic binder, and as cement fibrolite plate, plasterboard, though improved its waterproof, fire protecting performance, this sheet material is not shock-resistant, frangible, can not resemble to saw, follow closely, dig processing the wood.A kind of is the inorganic three-ply board of binding agent with magnesia and magnesium chloride, has overcome shock-resistant and not frangible defective, but still can not do processing such as plane, fluting as timber, and Application Areas still is restricted.
The object of the present invention is to provide waterproof, fire protecting performance good, light specific gravity, easy-formation, cost is low, can do saw, nail as timber, dig processing, building board easy to use.
Solution of the present invention is to be framework material with the wood fibre, adds the composite building board that coupling agent and binding agent are made, and said here binding agent is a kind of inorganic binder.Said organic coupling agent comes down to a kind of organic binder bond, and it has bonding and regulates dual-use function.In the bonding of wood fibre, play collaborative and regulating action to inorganic binder, the wooden machining feature that the sheet material of making is had to saw, follow closely, dig.
A key character of the present invention is that the constituent of said artificial composite board comprises the inorganic binder of (weight %) 16.0-66.5, and it is selected from one or more the mixture in cement, magnesium cement, the sodium metasilicate; 2.3-16.5 organic coupling agent, it is selected from one or more the mixture in white glue with vinyl, urea-formaldehyde glue, the polyvinyl alcohol; 29.5-70.1 framework material, the inorganic binder that its preferred constituent proportioning is (weight %): 38.0-47.0; 5.2-12.0 organic coupling agent; 43.0-50.0 framework material, so operation can be sawed, be followed closely, dig to the composite board that constitutes.
Said in the present invention inorganic binder, it is selected from cement, magnesium cement and sodium metasilicate.It can select wherein one-component for use, also can select the mixture of several components for use.Here used inorganic binder, its major function is cementation, the while also can be reduced the cost of sheet material and be improved fire prevention, the fire resistance characteristic of sheet material.
The organic coupling agent that uses among the present invention, it is selected from white glue with vinyl, urea-formaldehyde glue phenol glue and polyvinyl alcohol.It can select wherein one-component for use, also can select the mixture of several components for use.The adding of organic coupling agent has changed the defective such as not shock-resistant, frangible of inorganic plate in the prior art, makes it to have the feature of sawing, follow closely, digging processing of timber.So the selection of organic coupling agent and inorganic binder relative scale is one of key character of the present invention, both optimum mixs are 1: 3.0-6.6, and the best proportioning of framework material and inorganic binder is 1: 0.8-1.3.
The used framework material of the present invention then is selected from wood fibres such as wood shavings, wood chip, sawdust, bamboo chip, and various strings or crop stalk can be selected according to the local resources characteristics.
The production method of artificial composite plank of the present invention is: (a) mix inorganic binder in proportion and organic coupling agent is made slurry; (b) lignocellulosic material that adds the framework material of proportional quantity is made batch mixing; (c) break into type at the template arsis; (d) then send into the press hot-press solidifying, the temperature of hot-press solidifying is 80-140 ℃, and pressure is 14.7 * 10
4-19.6 * 10
4Pa; (e) the said artificial composite board of the present invention is so just made in finally demould, shaping.Use this sheet material fire prevention, good waterproof performance, light weight, and can saw, dig, follow closely processing as timber.
Further specify technical process of the present invention with a concrete instance more below.In mixer, drop into 12.5 kilograms of ordinary cements, add suitable quantity of water and mix slurry and then add after 1.5 kilograms of white glue with vinyl and 2.5 kilograms of urea-formaldehyde glues mix, add 17.5 kilograms of wood shavings again and mix thoroughly, pour into pat moulding in the template after, send into press 14.7 * 10
4Under the pressure, and be heated to 90 ℃, hot-press solidifying goes out machine after about 30 minutes sends curing room to and continue to solidify 48 hours at 30-60 ℃, and demoulding shaping then obtains thickness and be 8 millimeters 3 square metres of composite plates.
The artificial composite plank of so making, product quality meet the GB/T4897-92 standard.
Advantage of the present invention is clearly, and is tasteless by the sheet material that the present invention makes, light weight, and the intensity height, fire prevention, good waterproof performance, easy-formation, with low cost.Can saw, follow closely, dig processing as timber, can also remake various incrustations on the surface, can replace the various wood-based plates of selling on the existing market of not preventing fires, be a kind of building board economical and practical, easy to use.
Further specify the present invention with several embodiment more below, be not confined to this several example formulations scopes certainly. embodiment 12345 forms 45.5 44.8 47.6 47.6 61.4 performances such as (%) ordinary cement 42.4 44.8 44.4 44.4 25.7 white glue with vinyl 4.5 7.9 urea-formaldehyde glues, 7.6 phenol glue 7.9 12.7 polyvinyl alcohol, 10.4 wood shavings or sawdust
Can saw, dig and to saw, follow closely, dig, can saw, follow closely good springiness
Nail, the performance cost is low, the functional fire prevention of the excellent plane of performance is poor
Good embodiment 6789 10 forms 44.1 43.8 37.9 29.5 70.1 performances such as (%) ordinary cement 44.1 46.7 53.0 66.4 16.6 sodium metasilicate 4.4 7.3 4.5 2.1 white glue with vinyl, 2.2 phenol glue 13.4 polyvinyl alcohol, 7.4 4.5 2.1 wood shavings or sawdust
Can saw, follow closely, dig functional hardness height, the hardest, good springiness
It is the poorest to dig the frangible performance poor performance fire prevention of performance
