Description
Technical field
The present invention relates to the compound preparation technical fields of Lauxite, more particularly to tourmaline answering in Lauxite
It closes and is prepared by application.
Background technique
Lauxite is also known as urea formaldehyde resin.English abbreviation UF is urea and formaldehyde in catalyst (alkalinity or acidic catalyst
Agent) under effect, it is polycondensed into initial stage Lauxite, then again under curing agent or promoter effect, forms insoluble, insoluble latter stage heat
Thermosetting resin.Lauxite color after solidification is more shallow than phenolic resin, and be translucent shape, weak acid resistant, weak base, good insulation preformance,
Wearability is splendid, cheap, it is that the maximum kind of dosage is especially in the various wood-based plates of wood-processing industry in adhesive
In manufacture, Lauxite and its modified product account for 90% or so of the total dosage of adhesive.However, chance strong acid, highly basic easily decompose, it is resistance to
Time property is poor, it is just viscous it is poor, shrink that big, brittleness is big, not resistant to water, easy to aging, manufactured and made with the wood-based plate of Lauxite production
With the problem of there is Form aldehyde releases in the process, it is therefore necessary to be modified to it.
But existing Lauxite is complicated for operation in the preparation, the urea that can not be prepared on a large scale, and processed
Urea formaldehyde performance is unstable, it is therefore desirable to invent a kind of novel processing method to solve the above problems.
Summary of the invention

With preparation.
The present invention through the following technical solutions to achieve the above objectives:
A kind of compound and application preparation of tourmaline in Lauxite, compound in Lauxite of the tourmaline and
Using the preparation method of preparation, steps are as follows:
A, the formalin for pouring into 30L in a kettle starts blender while being slowly heated, and then uses hydroxide
Sodium solution adjusts the pH value of formalin, so that the pH value of formalin is maintained between 8~8.5；
B, then the urea powder of 5.6kg is added in reaction kettle, stirring is opened after raising the temperature to 60 DEG C to dissolving
Beginning timing, the pH value for adjusting reaction system are maintained at 8.5 or so, carry out insulation reaction；
C, 80 DEG C are continuously heating to, 2.8kg urea is added, then adjust reaction system pH value with 10% aqueous formic acid
Range is 5.4~6.0, and carries out insulation reaction again；
D, the tourmaline powder of 1kg after reaction, is poured into a kettle, and is stirred；
E, it in the process, is constantly sampled and instills in cold water, it is existing whether observation solution atomization occurs in cold water
As；
F, after there is atomizating phenomenon, add 2.8kg urea, and adjust pH value and reach 7.0~7.5, at 80 DEG C after
In warm water up to there is atomizating phenomenon in continuous reaction, after there is atomizating phenomenon, is cooled to 40 DEG C at once, terminates solution after reacting
PH value is adjusted to 7, then adjusts pH value to 8.5~9 with sodium hydroxide solution；
G, preparation terminates, and solution is taken out and is bottled.
Further, the heating method in the step a uses heating water bath.
Further, the concentration of sodium hydroxide solution is 10% in the step a.
Further, the insulation reaction time is 2~3 hours in the step b.
Further, the insulation reaction time is 1~1.5 hour in the step c.
Further, in the step d be added tourmaline powder when for slow component partition be added, and using blender into
Row stirring.
Further, before tourmaline powder being added in the step d, a certain amount of water-proofing agent, formaldehyde bonding agent can be added
And anti-aging agent.
Further, before tourmaline powder being added in the step d, a certain amount of catalyst need to be added, terminate in preparation
Afterwards, catalyst is filtered out.
Further, the warm water temperature of the detection atomizating phenomenon in the step f is 40 DEG C.
Further, the solution for being finely adjusted pH value in the step f is ammonium hydroxide.
The beneficial effects of the present invention are: in the Lauxite of heating tourmaline is added, in the catalytic action of catalyst
Lower carry out recombination reaction, makes Lauxite not only have self-characteristic, has been provided simultaneously with piezoelectricity and pyroelectricity, increase ureaformaldehyde
The use scope of resin, and preparation method is simple, at low cost, pollution is small, convenient for large-scale production and uses.
