Abstract
The invention discloses phenolic resin and a preparation method thereof, belonging to the preparation of resin. The raw materials of the phenolic resin comprise phenol, formaldehyde, paraformaldehyde and the like. The preparation method utilizes the characteristic of low water content of the paraformaldehyde to control the moisture of a phenolic resin finished product by controlling the proportion and the reaction level of the formaldehyde and the paraformaldehyde in the synthesis process of the phenolic resin so as to achieve the purpose of no need of dehydration in the process of preparing the phenolic resin. The invention has the benefits of not only realizing the zero emission of the waste water containing phenol, and eliminating the problem of the environmental pollution of the waste water containing the phenol, but also realizing energy conservation and reducing the emission of greenhouse gases, and further realizing the double win of the economic benefit and the social benefit.
Description
Technical field
The present invention relates to a kind of preparation method of resin.Specifically a kind of resol and preparation method.
Background technology
Enter 21 century, the economy of China has obtained the development of advancing by leaps and bounds, but along with rapid development of economy, problem of environmental pollution is also more and more serious.Country more and more payes attention to environment protection; adopt the preparation method of traditional resol to prepare resol; in process of production; produce a large amount of industrial phenolic wastewater; the industry phenolic wastewater is one of harmful waste water of keypoint treatment in China's water pollution control; wherein phenol resin production waste water contains the organism such as phenol, aldehyde and resin of high density, has characteristics such as high organic concentration, high toxicity.To the handling procedure complexity of this industrial phenolic wastewater, effect is also undesirable.Bring very big pressure for resol manufacturing enterprise, seriously restricting the development of enterprise.Cause a lot of enterprises to face the immense pressure of shutting down, stop, merge and change, influence the development of local economy.
Along with the deep enforcement of national energy-saving and emission-reduction policy, the influence of conventional industries is progressively manifested.In the traditional preparation process method of resol, owing to contain a large amount of moisture content in the formaldehyde, cause moisture content severe overweight in the work in-process, have in the later stage of resol preparation process, carry out dehydration operation, the solidified characteristic because resol is heated can only be carried out the negative pressure dehydration, will accompany heat in dehydration, the exhaust emissions of fuel has strengthened Greenhouse effect.Therefore the novel preparation method of resol has realistic meanings.
Summary of the invention
For overcoming the above-mentioned deficiency of prior art, the invention provides a kind of resol and preparation method.
The present invention realizes with following technical scheme: a kind of resol is the main raw material preparation with phenol, formaldehyde, NaOH solution and Paraformaldehyde 96, and the weight part of each raw material is:
1000 parts of phenol
Formaldehyde 100-200 part
50%NaOH 20-30 part
Paraformaldehyde 96 400-500 part.
The preparation method of above-mentioned resol, concrete steps are:
1) with the pre-heat fusing of phenol;
2) reinforced: as in whipping process, to feed in raw material successively: earlier with preheating fused phenol with in the vacuum mode sucting reaction still; The basic catalyst that then adds phenol weight 1-5%; Be warming up to 80 ℃, add formaldehyde down, carry out polycondensation, insulation reaction 0.5 hour at 80 ℃; Add Paraformaldehyde 96 according to response situation then, insulation reaction 1-2 hour, the control molecular weight was at MV300-500 in batches;
3) cool to below 40 ℃ the back blowing get resol.
The invention has the beneficial effects as follows: it is lower than the resol cost of traditional preparation process method production to use the resol of the present invention's production.Production process does not produce phenolic wastewater, than the preparation method of traditional resol 500 yuan of saving per ton on the processing cost of phenolic wastewater, has increased economic benefit to enterprise.Not only realize the zero release of phenolic wastewater, stop the problem of environmental pollution of phenolic wastewater, also realize the discharging of save energy, minimizing greenhouse gases, realized the doulbe-sides' victory of economic benefit and social benefit.
