Description
Technical field
The invention belongs to chemical technology field, and in particular to a kind of new application of phthalylhydrazine, i.e. phthalyl
Application of the hydrazine in gravity flow self-leveling floor paint is prepared.
Background technology
Phthalylhydrazine, molecular formula：C8H6N2O2, molecular weight：162.15 No. CAS：1445-69-8, fusing point：342-
344℃.Phthalylhydrazine structural formula is as follows：
Phthalylhydrazine is industrial production accessory substance：General source is phthalic anhydride as amino protecting group, after hydrazinolysis
Obtain phthalylhydrazine.Phthalylhydrazine is substantially insoluble in water and organic solvent, easily separate out separation after reaction and
It is widely used.At present, document report phthalylhydrazine has multiple use：201110375934.X report phthalyl
Hydrazine and nitric acid reaction, oxidation obtain phthalic acid.201510983063.8 report is using phthalylhydrazine as raw material, and acetyl
Reacted after changing reagent reacting with nitroso compound, nitroso phthalylhydrazine is obtained through deacetylation；Again through reduction
Reaction obtains different luminol.201610157868.1 after reporting phthalylhydrazine and oleum reaction, chlorine reaction is passed through
Prepare monoethyl diformylhydrazine and carry out fluorination reaction again, obtain ptfe phthalate.Several purposes of document report all need
To be reacted with nitric acid, acetic anhydride acylation reagent and oleum etc., produce substantial amounts of acid pickle, be unfavorable for safety and environmental protection,
Large-scale consumption, which utilizes, to acquire a certain degree of difficulty, costly, price inversion.
Epoxide terrace is a kind of high intensity, wear-resistant floor attractive in appearance, have solid seamless, quality, anti-corrosion, it is dust-proof,
The advantages that easy maintenance, cheap maintenance cost.Epoxy self-leveling floor paint is a kind of new paint vehicle, has green and gloss
Spend high characteristic；It is generally applicable in all kinds of construction, is a kind of paint of environmental protection and public nuisance free.At present, it is newest
Floor decorative material is exactly gravity flow self-leveling floor paint.Epoxy resin gravity flow self-leveling floor paint has turned into China's industry with the fastest developing speed
One of, it is possible to achieve large-scale production, application prospect are more considerable.
Have not yet to see the report that phthalylhydrazine is used to prepare gravity flow self-leveling floor paint.
The content of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of new application of phthalylhydrazine, i.e., adjacent benzene two
Application of the formylhydrazine in gravity flow self-leveling floor paint is prepared.
The present invention is realized by following technical schemes：
Application of the phthalylhydrazine in gravity flow self-leveling floor paint is prepared.
Above-mentioned phthalylhydrazine is in the application in preparing gravity flow self-leveling floor paint, the system of the gravity flow self-leveling floor paint
It is standby, comprise the following steps：
S1, polyamide are uniformly mixed with diluent；
S2, phthalylhydrazine is added, is stirred, sealing placement makes its dissolving；
S3, epoxy resin is added, stirs, produces.
Diluent is acetone, butanone, 2 pentanone, propione etc. in the step S1, in methanol, ethanol, isopropanol, propyl alcohol
One kind.It is preferably acetone, one kind in ethanol.More preferably acetone.
Diluent usage amount is the 25-75% of weight epoxy in the step S1.Preferably 40-50%.
The addition of phthalylhydrazine is the 10-20% of weight epoxy in the step S2.Preferably 15-17%.
Phthalylhydrazine is 100-200 evenly drying powder now in the step S2, preferably 150 evenly dryings now
Powder.
Phthalylhydrazine belongs to conjugated structure, and stability is good, is not susceptible to the chemical reaction such as conventional decomposition and open loop；
But strong oxidizer with hot conditions can open loop into acid, i.e. phthalic acid, acid anhydrides is further made；But cost is higher,
But also certain environmental pollution can be brought, every cost is then added when being further processed.This patent is developed for the product
New application, solves the problems, such as solid waste, because its chemical property is stable, nontoxic green, so as to turn waste into wealth develop it is new
Purposes.
The beneficial effects of the present invention are：
（1）The advantages of present invention is good using phthalylhydrazine stability, and toxicity is low, utilizes two activity in phthalylhydrazine
Hydrogen participates in reaction, partly prepares gravity flow self-leveling floor paint instead of polyamide and polymerization of epoxy resins.Gravity flow prepared by this method
Flat floor paint elongation at break increases to about 15% by about 3.5%, improves substantially, and hardening time about extends two days, so that construction
It is more prone to, particularly spring and autumn and summer becomes apparent.
（2）Phthalylhydrazine is industrial production accessory substance, disregards the cost of phthalylhydrazine；Polyamide is general
18.5 yuan/kg（Ton valency）, gravity flow self-leveling floor paint more directly uses epoxy resin and polyamide after adding phthalylhydrazine
Cost declines 3.5 yuan/kg.
Embodiment
The present invention is further described with reference to specific embodiment, so that those skilled in the art knows more about
The present invention, but and it is not so limited the present invention.
The epoxy resin and polyamide used in the embodiment of the present invention, be purchased from-the wooden chemical industry share in Jiangsu three is limited
Company.
