Abstract
The present invention relates to a kind of medicament that is used for epoxy resin cure, be specially adapted to low temperature, wet environment and underwater construction operation.It is phenol, quadrol that this solidifying agent adopts raw material, with its mixing, is constantly adding Paraformaldehyde 96 gradually under the agitation condition, and water-cooled cooling adds toughner, thinner more simultaneously, and solidifying agent gets product.The present invention not only has the advantage of non-toxic efficient solidifying agent, and the technological process of production is short, does not need thermal dehydration, and no harmful waste water discharging can form curing, dilution, toughening effect to Resins, epoxy naturally during application.
Description
The present invention relates to a kind of medicament that is used for epoxy resin cure, be specially adapted to low temperature, wet environment and underwater construction operation.
At present, synthetic epoxy resin generally all will add solidifying agent and toughner, with the use properties of further raising Resins, epoxy.Generally adopt quadrol to make solidifying agent in the prior art.When this medicament is used for epoxy resin cure, can volatilize a kind of more supervirulent irritant gas, skin is had corrosive nature, jeopardize health of human body, its application conditions is also limited in addition, promptly can not use in low temperature (below 5 ℃) and underwater operation or wet environment.In construction process, cause the curing operation environment abominable, dangerous for above-mentioned reasons, curing speed is low, has a strong impact on construction speed and quality, has also improved construction cost relatively.The present inventor develops a kind of non-toxic efficient solidifying agent (applying for a patent simultaneously) at above-mentioned shortcoming, and its raw material sources is abundant, and manufacturing process is easy, and is safe in utilization, does not have harm, has improved application conditions.But this solidifying agent is in manufacturing processed, and the production cycle is long, and thermal dehydration need expend a large amount of energy, especially contains free phenol water and aldehyde amines harmful waste in the water that discharging is deviate from.The equipment of handling these discharge waters is expensive many, and brings a lot of difficulties to wastewater treatment work, then wants contaminate environment as not handling.
The purpose of this invention is to provide a kind of multifunctional curing agent, it not only has the advantage of non-toxic efficient solidifying agent, and the technological process of production is short, does not need thermal dehydration, no harmful waste water discharging can form curing, dilution, toughening effect to Resins, epoxy naturally during application.
The object of the present invention is achieved like this: it is phenol 18-22 that this solidifying agent adopts raw material weight per-cent, quadrol 35-40, with its mixing, constantly adding Paraformaldehyde 96 18-22 gradually under the agitation condition, the while water-cooled cooling, add toughner 10-15 again, thinner 10-15, solidifying agent gets product.Its water-cooled temperature control is advisable at 50-120 ℃, time 2-3 hour, also can determine the size or the length of temperature control time of water-cooled temperature according to actual production conditions.
Because medicament of the present invention adopts raw material phenol to mix with quadrol, under stirring state, add Paraformaldehyde 96 gradually, add toughner and thinner behind the temperature control, need not thermal dehydration, get product, compare with the technology of producing non-toxic efficient solidifying agent, except that having its whole advantages, this technical process is short, so the energy that expends can save because of dehydration the time, particularly do not discharge the waste water that contains objectionable impuritiess such as free phenol, prevent contaminate environment effectively.Also solve simultaneously the difficulty that wastewater treatment work brings, saved equipment expense.Solidifying agent of the present invention does not carry out dehydration procedure, so its viscosity ratio currently available products is low, mutual solubility, toughness, curing speed, cured article intensity all are better than like product, and nature shape is to becoming epoxy resin cure, dilution, toughness reinforcing multiple function, so more suitable wide popularization and application during practical application.
The invention will be further described below in conjunction with implementing.
Embodiment 1: take by weighing phenol 80g according to quantity, quadrol 150g adds Paraformaldehyde 96 70g with its mixing gradually under constantly stirring, the while water-cooled cooling, controlled temperature adds toughner alkylphenol 40g again at 50-120 ℃, thinner dehydrated alcohol 30g can make about 370g finished product solidifying agent.
Embodiment 2: take by weighing phenol 95g according to quantity, quadrol 160g adds Paraformaldehyde 96 80g with its mixing gradually under constantly stirring, the while water-cooled cooling, controlled temperature adds toughner alkylphenol 60g again at 50-120 ℃, thinner dehydrated alcohol 30g can make about 420g finished product solidifying agent.
Toughner in the above-mentioned example, thinner also can adopt other similar preparation.
During use,,, get final product with the Resins, epoxy mixing by the actual proportioning that needs of using with solidifying agent of the present invention.
The chemical formula of solidifying agent of the present invention is:
（CH2）3 N2H4C6H5-OH
The key technical indexes of solidifying agent of the present invention is:
1, outward appearance: brown yellow transparent liquid
2, viscosity: 600 ± 100 centipoises
3, amine value: 470 ± 30mg/g.
