Abstract
The prsent invention relates to a wood imitated material and a production method thereof. The present invention is characterized in that reactive products of rock phosphate powder and sulfuric acid are used as modifying agents of urea-formaldehyde resin or melamine-formaldehyde resin and fillers of curing agents to quickly form a thermosetting material at the room temperature. Inorganic or organic fiber materials, inorganic or organic light materials can be added in the thermosetting material. The majority of raw materials can be obtained from industry, agriculture and people daily life waste materials. The wood imitated material has the advantages of water prevention, no combustion, light weight, excellent abrasion resistance, good intensity and simple manufacture. The wood imitated material can be quickly formed by moulds and is a building material with wide application.
Description
The invention belongs to material of construction, is a kind of imitated wood material.
The feature of production method of the present invention is: rock phosphate powder is broken into powder, in Rock Phosphate (72Min BPL), add an amount of sulfuric acid, produce resultant behind chemical reaction as properties-correcting agent, solidifying agent and the filler of urea-formaldehyde resin or terpolycyantoamino-formaldehyde resin with the two, mix with it form a kind of room temperature fast-curing, water-fast, do not fire, ageing-resistant, resistance to deformation, have excellent abrasive and have the thermoset material of better intensity.The normally many porous bodies of this material, lightweight has the heat-insulating sound-insulating function.
The principle of its formation is: Rock Phosphate (72Min BPL) mainly contains P
2O
5, CaO, all the other also contain SiO
2, F, CO
2, MgO, NaO
2, Fe, Al
2O
3, what have also contains Al, K, organic C etc.Rock phosphate powder generates calcium phosphate earlier after adding sulfuric acid, and then touring down phosphoric acid and the calcium sulfate of generating of supersaturation sulfuric acid state.F participates in reaction and then generates H
2SiF
6, reaction generates SiF again
4+ 2 (HF) produce gas, contain SiF in the gas
4, HF, phosphoric acid steam and water droplet.SiF in the gas
4Absorbed by water, be reduced to SiF
6, and produce silica gel (SiO
2.nH
2O).Fe in the ore, Al reaction generates (2Fe.Al) PO
4, Na, K reaction generates (Na.K) SiF
6Above resultant is with after urea-formaldehyde resin or terpolycyantoamino-formaldehyde resin mix, make it fast setting under sour environment, simultaneously phosphide, silicide, fluorochemical, sulfide etc. produce same function with it in solidification process, thus formed at last water-fast, do not fire, wear-resisting, have a type material of intensity, porous, light weight preferably.Because rock phosphate powder is an inorganic materials, the adding of these inorganic materials has reduced shrinking percentage, has increased non-deformability, has also increased the corrosion resistant ageing-resistant performance.
In the material of above formation, can add terra alba.After adding terra alba, the stiff foam material of better intensity is stablized and had to formation lightweight, body fast.It is a kind of imitative preferably wooden material of construction.
The process of Wet-process phosphoric acid (WPPA) in the phosphatization industry utilizes Rock Phosphate (72Min BPL) and sulfuric acid to carry out chemical reaction exactly, generates and extract the process of phosphoric acid.After extracting phosphoric acid, can produce the phosphogypsum of compounds such as containing part phosphoric acid and silicon, fluorine in a large number.If these phosphogypsums are not utilized and discard, can pollute environment.If these resistatess do not carry out special environmental protection treatment, pH value still can be 1.5-2 usually.And these conditions just in time are fit to production method of the present invention, and can make full use of.That is to say, directly mix, obtain above-mentioned materials of the present invention easily with urea-formaldehyde resin with above-mentioned phosphogypsum.For the utilization of phosphogypsum opens up a new way.
In the material of above formation, for improving anti-folding, tensile strength, can add inorganic fibers as glass fibre.Adding simple glass fiber not only can improve the pulling force of material, has the slow effect that discharges alkalescence owing to add glass fibre, can in and original material in acidity, the regulation and control pH value, thereby make material structure stable and ageing-resistant, can also add organic fibrous material and be wood (bamboo) bits, palm fibre, fiber crops and agricultural tangerine bar and cotton or chemical measuring fiber.
In above-mentioned materials, can add the organic or inorganic light material, as: polystyrene foamed plastics, pearlstone, corn stalk, sunflower bar etc. also can add diatomite.
In order further to gain in strength or to increase other performances.On the basis of above-mentioned materials, can add polyvinyl alcohol, polyvinyl acetate (PVA), styrene-propene yogurt liquid, vinylbenzene.
The present invention can obtain society, ecology, economic benefit:
The invention belongs to the disposal of waste gas, water and industrial residue category.The starting material that the present invention relates to all can obtain from industry and people's daily life waste material except that urea-formaldehyde resin, terpolycyantoamino-formaldehyde resin.Except that phosphogypsum, can utilize the polystyrene foamed material of discarded wrapping material, as the tangerine bar of agricultural waste, as the old measuring fiber material of people's daily life waste material.
The present invention can save energy consumption.The material of invention is low pressure die forming, room temperature fast-curing, seasoning or low temperature (≤60 a ℃) drying.This simple production method is not only saved the energy, has also reduced investment of production equipment.
Because above two factors have determined that product of the present invention is cheap.
Material of the present invention is not owing to fire, water-fast, lightweight, have excellent abrasive, have good intensity, sound-insulating and heat-insulating, has composite performance preferably simultaneously, and can saw, can dig, can follow closely, the workability energy of available die forming, thereby have extensive use.Can make the decoration carved on paste member in the material of construction; Can make partition wall or sheet material; Can make furniture; Especially imitative redwood carved furniture; But manufacture craft artistic products.Also can be used as wrapping material use etc.
Embodiment: make an imitative redwood Chinese style furniture carving table pin.
