Abstract
The present invention relates to a kind of novel environment-friendly furane resins, by weight ratio for：The step of 420 parts of chaff, 300 parts of formalin, 150 parts of urea, 80 parts of acetone, 20 parts of silicon gastral cavity, preparation method：First by 420 parts of chaff in above-mentioned material, 300 parts of formalin and the disposable input reaction ax of 150 parts of urea, it is sufficiently stirred；Then add sodium hydrate aqueous solution into reaction ax, the pH value for adjusting solution in reaction ax is 8, is warming up to 65 DEG C, soaking time is 0.5 hour；The pH value of solution in reaction ax is adjusted to 6.5 again, is warming up to 95 DEG C, the insulation reaction time is 1.5 hours；Reaction ax is cooled to 85 DEG C again, 10 parts of 20 parts of silicon gastral cavity, 80 parts of acetone and urea, insulation reaction 0.5 hour is added；Final reaction axe is cooled to 70 DEG C, and adjustment pH value discharges after being 7.5, and the present invention reduces dewatering process, shortens the time, not only avoids sewage discharge and pollute environment, and reduces energy consumption and recruitment cost, also improves resin-bonding intensity.
Description
Technical field
The present invention relates to resin materials to prepare technical field, and in particular to a kind of novel environment-friendly furane resins and its preparation
Method.
Background technology
Resin material production is required for using industrial formaldehyde solution being raw material, using distillation dehydration technique, due to industrial first
Aldehyde solution aqueous 63% or so needs to improve mechanical strength of resin and control free formaldehyde to carry out large amount of sewage discharge.It is in strong acid in sewage
Property, contain a large amount of monomer free formaldehyde（Content 3%-5% or so）, a 500 Dun Kuai furane resins enterprises of annual output.Only in dehydration discharge
Contaminant water is stated up to nearly kiloton, very big ground contamination environment and the energy waste for causing dehydration to produce and recruitment cost.
Invention content
In order to overcome above-mentioned shortcoming existing in the prior art, the purpose of the present invention is to provide a kind of novel environment friendlies
The preparation method of type furane resins, this method are needed not move through de- in being prepared furane resins production using industrial formaldehyde solution
Hydraulic art is avoided the problem that and is solved to prepare in furane resins production and discharges large amount of sewage.
To achieve the above object, the technical solution adopted by the present invention is as follows：A kind of novel environment-friendly furane resins, by weight
Proportioning is：
400-450 parts of chaff
300 parts of formalin
150 parts of urea
80 parts of acetone
20 parts of silicon gastral cavity.
A kind of preparation method of above-mentioned novel environment-friendly furane resins, includes the following steps：
A, 150 parts of 400-450 parts of chaff in above-mentioned material, 300 parts of formalin and urea are disposably put into reaction ax, into
Row is sufficiently stirred；
B, add sodium hydrate aqueous solution into reaction ax, the pH value for adjusting solution in reaction ax is 8, is warming up to 65-70 DEG C, heat preservation
Time is 0.5 hour；
C, the pH value of solution in step B is adjusted to 6-7, is warming up to 95 DEG C, the insulation reaction time is 1.5 hours；
D, reaction ax in step C is cooled to 85 DEG C, 10 parts of 20 parts of silicon gastral cavity, 80 parts of acetone and urea is added, continue insulation reaction
0.5 hour；
E, reaction ax in step D is cooled to 70 DEG C, adjustment pH value is discharged after being 7.5 obtains product.
Compared with prior art, the invention has the advantages that：
1, present invention reduces the preparation process of furane resins, reduce energy consumption and recruitment cost, especially with pyroreaction, increase
The strand of big urine aldehyde, improves resin-bonding intensity, main not have to dehydration, avoids the discharge of contaminant water and to the tight of environment
Heavily contaminated.
2, furane resins of the present invention are in free formaldehyde, and production cost, use environment and nitrogen content etc., which have, greatly to be changed
It is kind.
3, preparation method of the present invention can be directed to user and adjust material proportioning, obtain different quality index products.Feasible reality
The solution that border can not be run.
Specific implementation mode
With reference to embodiment, the invention will be further described, and mode of the invention includes but are not limited to following implementation
Example.
Embodiment 1
A kind of novel environment-friendly furane resins, by weight ratio for：420 parts of chaff, 300 parts of formalin, 150 parts of urea, acetone
80 parts, 20 parts of silicon gastral cavity, preparation method, include the following steps：First by 300 parts of 420 parts of chaff in above-mentioned material, formalin
In 150 parts of disposable input reaction ax of urea, it is sufficiently stirred；Then add sodium hydrate aqueous solution into reaction ax, adjust
The pH value of solution is 8 in whole reaction ax, is warming up to 65 DEG C, soaking time is 0.5 hour；Again by the pH value tune of solution in reaction ax
Whole is 6.5, is warming up to 95 DEG C, the insulation reaction time is 1.5 hours；Reaction ax is cooled to 85 DEG C again, 20 parts of silicon gastral cavity, third is added
10 parts of 80 parts of ketone and urea, continue insulation reaction 0.5 hour；Final reaction axe is cooled to 70 DEG C, and adjustment pH value carries out after being 7.5
Discharging.
Above-described embodiment is only the preferred embodiment of the present invention, should not be taken to limit protection scope of the present invention, but
All body design thought in the present invention and that mentally makes have no the change of essential meaning or polishing, the technology solved
Problem is still consistent with the present invention, should all be included within protection scope of the present invention.
