Abstract
A kind of method of producing sheet material or other special-shaped products is disclosed.This method is included on the plants particles material, and the coating hydrophilic polyurethane prepolymers again with the bulk forming that obtains, makes molded article solidify and drying at excessive in water solutions or dispersion liquid then.Can also contain or not contain the inert polymer adhesive in the coating liquid.
Description
The present invention relates to a kind of method of producing flexible sheet material or other special-shaped products from plants particles material.
Japanese Laid-Open Patent Application 106932/1984 discloses a kind of method of producing sheet material or other special-shaped products, it is to be with the polyurethane of isocyanate end to give polymers or polyisocyanate compounds by coating, by adhesive resin plants particles material is adhered to one another, roll extrusion forms then, perhaps the particulate mass group that obtains is depressed shaping adding.The polyurethane that is coated on the particle gives polymers or polyisocyanate compounds, and the chemical reaction of the active site that has with the moisture content in the atmosphere or with particle itself by NCO makes each particle crosslinked together.This method needs relatively large adhesive to give polymers or polyisocyanate compounds, and is unsuitable for producing by batch of cheap goods such as flowerpot.Hindered this method and be applied to producing continuously in batch of special-shaped products than the obstruction of long and mechanograph hardening time in addition.
The inventive method is that with the difference of prior art it can provide flexible sheet material or goods in the cheap mode of expense.
According to the present invention, a kind of method of producing sheet material or other special-shaped products is provided, its step comprises: apply a kind of aqueous mixture that polyurethane gives polymers that contains on plant granule, with the particle bulk forming that obtains, goods are solidified and drying.The used polymers that gives contains a lot of free isocyanate end, it is to be made with excessive PIC reaction by polyoxyalkylene Quito alcohol, the many alcohol of per molecule are with two hydroxyl end groups at least, wherein oxygen ethene chain link is calculated by weight and will be accounted for 10-90%, this contains the aqueous mixture that polyurethane gives polymers and contains excessive water far away, wherein can also contain the inert polymer adhesive.
The goods that obtain compacting under heating and pressurization again is to improve its strength character.
The used polyurethane of the present invention gives polymers, such just as we all know, can be made with excessive polyisocyanate compound reaction by poly (oxyalkylene) Quito alcohol, the many alcohol of per molecule are with two hydroxyl end groups at least, and wherein the weight of oxygen ethene chain link will account for 10-90%.Many alcoholic compounds itself can carry out addition reaction with the reactive hydrogen starting compound by the alkylene oxide mixture again and make.At least must contain two active hydrogen atoms in each molecule of these starting compounds, its example has ethylene glycol, propane diols, hydroquinones, bisphenol-A, 1.6-hexylene glycol, dimethyltrimethylene glycol, glycerine, trimethylolpropane, 1,2,6-hexanetriol, pentaerythrite, α-formaldehyde glycosides, sorbierite, sucrose, castor oil, 1,2-ethylenediamine, diethylenetriamines, piperazine, methylamine, just-butylamine, aniline, xylylene amine etc.The example of alkylene oxide comprises oxirane, expoxy propane, epoxy butane, styrene oxide, oxolane etc.The weight ratio of oxirane should be 10-90% in the alkylene oxide mixture.Addition reaction can be undertaken by known method.The molecular weight of the polyether polyol that makes with greater than 1000 for good.The oxygen ethene chain link that exists in each peg molecule chain can form random or block copolymer.If oxygen ethene chain link content is higher than 90%, for example 100%, this polyether polyol usually exists with solid-state in room temperature, and the polyurethane that makes thus gives polymers with the too fast hard state that is solidified into.On the contrary, if oxygen ethene chain link content is lower than 10% in the polyether polyol, the polyurethane that makes thus gives polymers and tends to not reach desired hydrophily.
The example of polyisocyanate compound has, toluene di-isocyanate(TDI) (refining or rough TDI), '-diphenylmethane diisocyanate (MDI), the poly-many phenyl isocyanate of ethylidene, hexamethylene diisocyanate, eylylene diisocyanate, naphthalene diisocyanate, IPDI and their mixture.
The polyurethane of end of the chain band free isocyanate groups group gives polymers, can be made with the polyether polyol reaction by polyisocyanate compounds, and the equivalent proportion of NCO/OH is 1.5 to 100, is good with 2 to 20 again.Obtain give polymers can be soluble in or be scattered in far away from the excessive water, can the bond slurry of plant pellet of formation, institute water the inside also can arbitrarily add certain polymer adhesive.Water plays the effect that polyurethane gives the chain-unfolding agent of polymers.
Slurry can be with the solution or the emulsion that contain or do not contain the inert polymer adhesive.The example of the water-soluble copolymer adhesive that is suitable for has polyvinyl alcohol, polyacrylic acid, polyacrylamide, water-soluble maleic acid etc.The example of polymer-bonded agent emulsion have natural or synthetic rubber latex such as natural rubber, butadiene-styrene rubber, neoprene, acrylonitrile-butadiene rubber, Acrylester Butadiene Rubber, isoprene rubber, butyl rubber, EP rubbers etc.Other polymer-bonded agent emulsion also can use, such as polyvinyl acetate, and polyvinyl chloride, Vingon, vinyl chloride-vinyl acetate copolymer, ethylene-vinyl acetate copolymer, polyacrylate, amino resins and phenol resin.
The ratio that water accounts in the slurry preferably equals polyurethane wherein at least and gives the total solid content of polymers and inert resin adhesive and be less than polyurethane and give polymers and inert resin adhesive total solid content 50 times.
The example of plants particles material has sawdust, wood chips, and cork powder, rice bran, oil-bound distemper, analysis for soybean powder, the shell of rice or cereal, straw, the bark that grinds etc., but be not limited to these.
Implementing the inventive method, at first is such as being coated on the plant pellet with spray technology with binder solution.The shaping compound that obtains spreads out on mat immediately to form sheet material, makes its curing and drying under room temperature or higher temperature.Described compound also can form desired shape with mould pressing process.If do not adopt the way of the binder liq that is pre-mixed of coating, can be first that the plant pellet is wetting with big water gaging, and then mix mutually with all the other components.
Shaping compound also can contain other additive commonly used, such as solvent, and plasticizer, defoamer, surfactant, colouring agent, filler, curing catalysts etc.
The sheet material that obtains or other special-shaped products, can the heating under compacting with its strength character of further raising.The pressure of this secondary operations is with 2 to 100 kilograms per centimeter
2Be advisable, again with 10 to 60 kilograms per centimeter
2Better, temperature then is advisable with 70 to 200 ℃, and is better with 100 to 170 ℃ again.
Method provided by the invention can or be worth little material from waste material, in the cheap mode of expense, produces useful sheet material and other special-shaped products with good flexibility and other strength character.
The example that provides below usefulness for illustrative purposes only.Unless indicate in addition, all umbers and percentage number average are calculated by weight.
