Description
Technical field:
The present invention relates to solidifying agent technical field and coating industry, particularly a kind of epoxy resin lalent solidifying agent and epoxypaint thereof.
Background technology:
At room temperature, in epoxy resin, latent curing agent can be stored for a long time, and under the conditions such as heating, curing reaction occurs.Wherein conventional epoxy resin lalent solidifying agent is Dyhard RU 100.It is distributed in epoxy resin, good stability, and normal temperature can reach more than 6 months working life, and cured article has good performance.But Dyhard RU 100 separately as solidification value during solidifying agent more than 170 DEG C, with epoxy resin and lower boiling solvent phase dissolubility bad, be unfavorable for make matrix material.
Dyhard RU 100 preparation single-component coating advantage is exactly mechanical property and good stability, and period of storage is long, but solidification value is high, and set time is long, and this is also the problem that same needs solve.
Summary of the invention:
One of order of the present invention is to provide a kind of epoxy resin lalent solidifying agent, and the curing performance of this solidifying agent is good, and solidification value is low, and storage stability is good, strong adaptability.Another object of the present invention is to provide a kind of epoxypaint, and the viscosity of this epoxypaint is low, and set time is fast, and solidification value is low, smooth, smooth, even, easy to use, and storage stability is good.
For achieving the above object, epoxy resin lalent solidifying agent of the present invention includes following parts by weight of component: Dyhard RU 100 80 ~ 90, carbamide derivative 30 ~ 50, silicon-dioxide 40 ~ 60, fibrous magnesium silicate 10 ~ 30, thinner 10 ~ 20, carbamide derivative is as the promotor of Dyhard RU 100, and its structural formula is:
R
1, R
2=simultaneously or represent hydrogen, C independently of each other
1-to C
10-alkyl, C
3-to C
12-cycloalkyl.
Preferred as technique scheme, described R
1, R
2=simultaneously or represent hydrogen, methyl, ethyl independently of each other.
Preferred as technique scheme, described thinner is polyglycidyl ether or acetone.
Epoxypaint of the present invention, every 100 parts of water comprise the following ingredients formed by mass percentage: epoxy resin 40%-55%, epoxy resin lalent solidifying agent 10%-20%, pigment 10%-20%, defoamer 5%-15%, thickening material 5%-15%, flow agent 5%-15%; Wherein, epoxy resin lalent solidifying agent includes following parts by weight of component: Dyhard RU 100 80 ~ 90, carbamide derivative 30 ~ 50, silicon-dioxide 40 ~ 60, fibrous magnesium silicate 10 ~ 30, thinner 10 ~ 20, carbamide derivative is as the promotor of Dyhard RU 100, and its structural formula is:
R
1, R
2=simultaneously or represent hydrogen, C independently of each other
1-to C
10-alkyl, C
3-to C
12-cycloalkyl.
Preferred as technique scheme, described thickening material is methylcellulose gum.
Preferred as technique scheme, described flow agent is acrylic acid or the like flow agent.
Beneficial effect of the present invention is: it adds carbamide derivative in dicy-curing agent is promotor, reduces solidification value, shortens set time.Silicon-dioxide hardness is high, as carrier be conducive to that solidifying agent and epoxy resin can mix simultaneously even, the contact area of both raisings, and then the performance improving solidifying agent.Therefore the present invention's curing performance of obtaining solving the problem is good, and solidification value is low, and storage stability is good, adaptable solidifying agent.And epoxypaint of the present invention is using epoxy resin lalent solidifying agent as base-material, be mixed with compositions such as epoxy resin, flow agent, defoamer and thickening materials that to have solidification value low, set time is short, viscosity is low, smooth, smooth, even, easy to use, and the epoxypaint that storage stability is good.
