Abstract
A production method of an environment-friendly fragrant curing agent by utilizing furan resin industrial wastewater comprises the following steps: preparing the following raw materials in parts by weight: 90 to 110 parts of furan resin industrial wastewater, 1.5 to 2.5 parts of polyatomic acid, 5 to 8 parts of amino acid, 3 to 6 parts of acrylic acid, and 10 to 15 parts of industrial water; putting the prepared raw materials into a reactor, stirring to carry out self-exothermic condensation and polymerization reactions, maintaining the temperature and carrying out the reactions for 50 to 70 minutes when the temperature rises to 36 to 46 DEG C; cooling the temperature to 25 to 30 DEG C, adding 0.2 to 0.4 part of odor preventing agent, stirring for 15 to 25 minutes, and filtering so as to obtain the curing agent. The production method solves the environment pollution problem brought by furan resin industrial wastewater, and brings economic benefit to entrepreneurs. The prepared curing agent comprises a plurality of organic materials and inorganic materials, has the advantages of large strength, high-temperature resistance, strong corrosion resistant performance, and good stability, has a smaller usage amount than that of convention curing agents, and is capable of being used as a curing agent for various resins.
Description
Technical field
The invention belongs to chemical technology field, relate to a kind of solidifying agent, particularly a kind of method utilizing furan resin industrial wastewater production environment-friendlyfragrant fragrant solidifying agent.
Background technology
Furane resin are a kind of important Chemicals, chemical property is relatively active, is be that main raw material is obtained, for high-temperature material, impregnating material, machine casting, aerospace, oceanographic engineering etc. by reactions such as condensations with furfuryl alcohol furfural, at present, furane resin obtain the attention of countries in the world.China from 20 beginnings of the century just produce furane resin, develop into up till now and produced ton up to a million per year, become the furane resin producing country that the whole world is maximum, but the method for traditional production furane resin can produce a large amount of trade effluent, about more than 30 ~ 400,000 tons every year.In furan resin industrial wastewater, organic content is high, mainly containing gas chromatographies such as acetic acid, aldehydes, ketone, polyvalent alcohols, is difficult to purifying treatment, causes very large pollution to environment, mainly contain following several treatment process at present:
1, chemical method: mainly by catalyzed reaction, the organic substance decomposing in furan resin industrial wastewater is separated taking-up and is used for resin, but remaining a large amount of furan resin industrial wastewater cannot process.
2, Physical: mainly reclaim the gas chromatographies such as the acetic acid in furan resin industrial wastewater by extraction-rectification, furan resin industrial wastewater is after extraction treatment, the grade III Standard of " integrated wastewater discharge standard " can be reached, but due to the complicated component of furan resin industrial wastewater, seriously polluted to extraction agent, easily cause secondary pollution, extraction agent consumption is large, and cost is higher.
These treatment processs all can not process furan resin industrial wastewater well, and easily produce secondary pollution, and running cost is higher in addition, and implementation result is all undesirable, make furan resin industrial wastewater become a great problem of contaminate environment.But the compounds such as the hydroxy derivatives contained in furan resin industrial wastewater and alcohols are good industrial chemicals, if can recycle furan resin industrial wastewater, not only can solve a difficult problem for furan resin industrial wastewater contaminate environment, and economic benefit can be brought to enterprise again, kill two birds with one stone, therefore, the recycle how realizing furan resin industrial wastewater becomes the research emphasis of those skilled in the art.
Summary of the invention
The object of the invention is the technical problem in order to solve furan resin industrial wastewater environment being caused to very large pollution, in order to address this problem, we devise a kind of method utilizing furan resin industrial wastewater production environment-friendlyfragrant fragrant solidifying agent, not only solve a difficult problem for furan resin industrial wastewater contaminate environment, and in production process, utilize self-heat generation to heat up, do not need heat energy to heat, save the energy, save production cost, brought economic benefit to enterprise, killed two birds with one stone.
Concrete technical scheme of the present invention is: a kind of method utilizing furan resin industrial wastewater production environment-friendlyfragrant fragrant solidifying agent, and key is: described method comprises the following steps:
A, by following mass ratio number proportioning starting material: furan resin industrial wastewater 90 ~ 110 parts, polyprotonic acid 1.5 ~ 2.5 parts, 5 ~ 8 parts, amino acid, 3 ~ 6 parts, vinylformic acid, process water 10 ~ 15 parts;
B, the starting material got ready in step a are added in reactor, stir and carry out from heat release polycondensation, when temperature is elevated to 36 ~ 46 DEG C, insulation reaction 50 ~ 70min:
C, when being cooled to 25 ~ 30 DEG C, add mask agent 0.2 ~ 0.4 part, stir 15 ~ 25min, filter and obtain solidifying agent.
The invention has the beneficial effects as follows: according to the principle of recycling economy, by the recycle under certain condition of the acetic acid in furan resin industrial wastewater, aldehydes, ketone, polyvalent alcohol and gas chromatography, reaction generate free sulfuric acid content less, without the novel environment friendly fragrance solidifying agent of noxious odor, turn waste into wealth, achieve the comprehensive utilization of resource.Utilize self-heat generation to heat up in production process, do not need heat energy to heat, save the energy, save production cost.Obtained solidifying agent contains gas chromatography and inorganics, and intensity is large, high temperature resistant, anti-corrosion capability is strong, and good stability is fewer than traditional hardener dose, can be used as the solidifying agent of various resin, both solved a difficult problem for furan resin industrial wastewater contaminate environment, brought economic benefit to enterprise again.
