Abstract
The present invention relates to a nontoxic epoxy toughening paint made from epoxy resins with the epoxy equivalent values of 0.04 to 0.54, a T31 and 650 composite solidifying system, a polyamide resin toughening agent (650), a silane coupling agent (KH-550), alcohols, nontoxic ketone solvents and nontoxic filling materials. The nontoxic epoxy toughening paint has little acute toxicity; the cumulative toxicity (K) is greater than 5; the micronucleus test indicates that the nontoxic epoxy toughening paint does not cause carcinogenic jumps. When a drinking water container coated with the nontoxic epoxy toughening paint is used for containing water, the water quality conforms to the drinking water standard in China. The percentage elongation at rupture of the nontoxic epoxy toughening paint is from 2 to 4%; the nontoxic epoxy toughening paint can be solidified at -10 DEG C with the relative moisture of 80%, and therefore, can be easily coated and sprayed at low temperature. The nontoxic epoxy toughening paint has the function of corrosion prevention, and the service life is longer than 10 years. The nontoxic epoxy toughening paint overcomes the defects existing in the present paint.
Description
Non-Toxic tough epoxy paint belongs to the chemistry painting industry technical field.
Existing epoxy coating generally all is deleterious.Though disclosed 89105340.9 non-poison and non-solvate epoxy paints of Chinese invention patent communique and preparation can reach nontoxic performance, can not solidify under low temperature, wet condition.And the viscosity of coating is big, should not brush under normal temperature condition, adopts the also difficult spraying of general-purpose equipment, and its range of application is restricted.Moreover the toughness of this coating is bad.
The objective of the invention is to develop a kind of nontoxic, and dope viscosity is low, intensity is high, good toughness, is easy to spraying and brushes under low temperature, wet condition, and be easy to the solidified epoxy coating.
The present invention is made up of Resins, epoxy, modified amine curing agent, toughner, coupling agent, solvent, filler.The composition and the parts by weight of this coating are respectively: oxirane value is 100 parts of the Resins, epoxy of 0.04～0.54 normal E-51, E-44, E-20, E-12 one or more combination, (auxiliary reagent factory, Kunshan, Kunshan City, Jiangsu Province produces modified amine curing agent T31 (phenol, formaldehyde, quadrol condenses), see " bonding and adhesive technology handbook, volumes such as Gao Xuemin, Sichuan science tech publishing house publishes.) make compound curing system (650 is again toughner simultaneously) with 650 (low molecule pa resins) (auxiliary reagent factory, Kunshan, Kunshan City, Jiangsu Province produces, and sees " synthetic adhesive "), the proportioning of T31 is 15～45 parts, 650 proportionings are 10～50 parts; Toughner selects low molecule pa resin 650 or biuret, and the low molecule pa resin proportioning is got 10～50 parts, and the biuret proportioning is got 1～50 part; Coupling agent selects silane resin acceptor kh-550 (γ-An Jibingjisanyiyangjiguiwan) (chemical plant, Gai County, Liaoning Province produces, see " bonding and adhesive technology handbook), and its proportioning is 0.5～5 part; Solvent selects nontoxic type alcohols or ketone, and proportioning is 20～60 parts; Filler selects the nontoxic type filler, and as one or more the combination in lithopone, titanium dioxide, silicon powder, talcum powder, the aerosil, proportioning is 20～120 parts; Pigment selects as required and adds (all cooperation ratios are 100 with Resins, epoxy all).
The toxicity that coating of the present invention gives environmental health monitoring and surveilliance institute of anti-research institute through China detects and the toxicity of Public Health College, Harbin Medical Univ is accredited as: acute toxicity: nontoxic substantially; Cumulative toxicity: K＞5; Micronucleus test: no Cancer-causing mutation; This coating is as drinking-water pipe, tank inner wall anticorrosion coating, and Sheng meets national hygiene standard for drinking water with water examination.Tension set: 2～4%, can under-10 ℃ and 80% relative humidity, solidify; Can adopt general-purpose equipment to spray and brush at low temperatures.Have antiseptic property, the life-span is more than 10 years.
Embodiment one: take by weighing Resins, epoxy 100kg, acetone solvent 25kg, put into reactor, start agitator and reflux, be heated to 80 ℃, make its dissolving.Take by weighing toughner biuret 10kg and add in the reactor, stirring reaction 2 hours is cooled to below 40 ℃.With the above-mentioned solution dispersion machine of packing into, start agitator, add filler 30kg, add a certain amount of pigment again, dispersed with stirring is even.Adding coupling agent KH550 again is 1kg.Continue to stir.Squeeze into colloidal mill then, wear into the standard fineness, barrelling becomes the first component.
Take by weighing solidifying agent 650 polyamide resin 15kg, T31 solidifying agent 16kg and go into dispersion machine.Take by weighing etoh solvent 10kg and go into dispersion machine, start agitator, stir evenly.Take by weighing filler 10kg and part pigment, be uniformly dispersed.With the above-mentioned colloidal mill of all squeezing into, wear into the standard fineness, barrelling becomes the second component.
By weight, first: second=used the mixing back in 3: 1 during use.
Claims (2)
1, non-Toxic tough epoxy paint, form by Resins, epoxy, modified amine curing agent, toughner, coupling agent, solvent, filler, it is characterized in that the composition of this coating and parts by weight are respectively: 100 parts of the Resins, epoxy of oxirane value one or more combination in 0.04～0.54 normal E-51, E-44, E-20, E-12; Modified amine curing agent selects T31 and 650 to make compound curing system, and the proportioning of T31 is 15～45 parts, and 650 proportioning is 10～50 parts; Toughner selects low molecule pa resin 650, and proportioning is 10～50 parts; Coupling agent selects silane resin acceptor kh-550, and proportioning is 0.5～5 part; Solvent selects nontoxic alcohols or ketone, and proportioning is 20～60 parts; Filler selects one or more the combination in lithopone, titanium dioxide, silicon powder, talcum powder, the aerosil nontoxic type filler, and proportioning is 20～120 parts.
2, non-Toxic tough epoxy paint according to claim 1 is characterized in that toughner selects biuret for use, and proportioning is 1～50 part.
