Abstract
The invention discloses plywood compound type filler, which is composed by the main raw materials of kaolin, plant straw powder and bauxite, and starch, coupling agent and other partial modified materials are additionally added. The kaolin, the bauxite and the plant straw powder which are smashed to a certain fineness are mixed to be put in a high-speed shearing compounding machine to carry out high-speed shearing and stirring, then starch, coupling agent and spice are added and are continuously stirred, and the compounding is completed after intensive mixing reaction. The compound type filler not only has the properties of thickening, tackification water absorption and the like of wheatmeal, but also has the advantages of free formaldehyde capture, strong flexibility, large bonding strength, long colloidity maintenance, slow aging property and the like.
Description
Technical field
The invention belongs to the plywood production technical field, especially relate to a kind of special-purpose stopping composition of producing the tackiness agent that wood veneer uses.
Background technology
At present; The tackiness agent that uses in the plywood production mainly is urea-formaldehyde resin, resol, and this tackiness agent is in order to prolong preservation period, and that generally does when dispatching from the factory is rarer; Solid content is lower than 46%; Be to increase resin initial viscosity, improve the precompressed effect of embryonic plate, reduce the cost of tackiness agent, wood veneer enterprise all will be in resin absorb fillers.Raw material as the tackiness agent weighting agent mainly is flour and bean powder now, all belongs to food crop, not only wastes grain, and price is high, has influenced economic benefit of enterprises.Wheat-flour can not be caught the free formaldehyde in the tackiness agent as stopping composition simultaneously.
Summary of the invention
The objective of the invention is to be directed against the problem that exists as stopping composition with wheat-flour in the prior art; A kind of plywood compound type filler is provided; The meal that mixes with inorganic mineral and organic plant straw is a basic raw material, adds partially modified material again, and the raw material lower through price replaces flour; And added the compsn that absorbs formaldehyde, solved the problems of the prior art.
The objective of the invention is to realize that through following technical scheme the compound type filler of said alternative wheat-flour is made up of the raw material of following weight part:
Kaolin 30-40
Aluminium vanadine 10-20
Plant stalk powder foam 25-35
Starch 2-3
Coupling agent 0.3-0.5
Spices 0.1-0.2
Compound type filler of the present invention is made up of the raw material of following most preferred weight part:
Kaolin 35
Aluminium vanadine 15
Plant stalk powder end 30
Starch 2.5
Coupling agent 0.4
Spices 0.15
Said kaolin is pulverized the 300-400 order; It is the 200-300 order that said plant straw is worn into fineness; Make xylogen and fiber separation, said the aluminium vanadine is worn into fineness is 250-350 purpose powder, and said coupling agent is a kind of of silane coupling agent; Said above kaolin, plant stalk powder end, aluminium vanadine powder are put in the composite machine of high speed shear; Carry out high speed shear and stirred 10-20 minute, and then add starch, coupling agent, spices and continue to stir 10-15 minute, treat after thorough mixing reacts to be composite completion.
The present invention accomplishes the technical indicator after composite: fineness: 300-350 order; Colourity: opaque pink; Potential of hydrogen: neutrality; Specific refractory power: 1.89%; Water cut: less than 0.01%; Proportion: 0.9; Initial viscosity: 1900-6800mpa.s.
Beneficial effect of the present invention: stopping composition not only possesses characteristics such as the thickening, tackify suction of wheat-flour, but also have the free formaldehyde of seizure, snappiness is strong, bonding strength is big, it is long to keep colloidality, aging waits advantage slowly.
Detect through overtesting, compound type filler each item technical indicator of the present invention all is superior to wheat-flour:
Test item compound type filler wheat-flour of the present invention
Initial viscosity 1900-6800mpa.s 1800-5000mpa.s
PH value 6.9-7.2 7.3-8.6
Colloid index 40-86 28-40
Embodiment
Embodiment one:
Get kaolin 35kg, aluminium vanadine 15kg, plant stalk powder end 30kg, starch 2.5kg, coupling agent 0.4kg, spices 0.15kg.Be ground into certain fineness kaolin, aluminium vanadine more than inciting somebody to action, put in the composite machine of high speed shear last mixing of plant stalk powder; Carrying out high speed shear stirred 15 minutes; And then add starch, titanate coupling agent, spices and continue to stir 12 minutes, treat after thorough mixing reacts to be composite completion.
Embodiment two:
Get kaolin 30kg, aluminium vanadine 17kg, plant stalk powder end 25kg, starch 3kg, coupling agent 0.5kg, spices 0.12kg.Be ground into certain fineness kaolin, aluminium vanadine more than inciting somebody to action, put in the composite machine of high speed shear last mixing of plant stalk powder; Carrying out high speed shear stirred 15 minutes; And then add starch, aluminate coupling agent, spices and continue to stir 12 minutes, treat after thorough mixing reacts to be composite completion.
