Wherein the component A comprises the following components: modified aliphatic curing agent, 5054 defoaming agent, flexibilizer, n-butyl alcohol and xylene; the component B comprises the following components: epoxy resin, iron oxide yellow, titanium dioxide, fumed silica, precipitated barium sulfate, n-butyl alcohol, xylene, cyclohexanol and DMF. The invention has the characteristics that: the coating has excellent chemical resistance, hot water resistance and cold-hot water alternation performance.
Description
One, technical field
The present invention relates to be used to feed water, draining with burying and the preparation method of the coating that preservative coat uses in the built on stilts cast-iron pipe, the particularly preparation method of corrosion-resistant epoxy paint in the cast-iron pipe.
Two, background technology
As the carrier of Urban water supply and draining, pipe must be embedded in underground or carry out work in dark moist place, and pipe certainly will have corrosion like this, and corrosion will reduce the application life of pipe, causes the loss of huge manpower and financial resources.So must carry out strict rotproofing to pipe, prolong the work-ing life of pipe.
Practical application shows to have only 3 years its work-ing life for not carrying out antiseptic pipe, can reach more than 10 years and carry out its life-span of antiseptic pipe.The different treatment processs and the difference of applied environment also can produce different influences to the corrosion of pipe.
Because the performance requriements to conduit is harsh, so the requirement of the impregnating material of pipeline is also very harsh, the one, hygienic environment-protecting is up to standard, and the 2nd, physical and chemical performance is up to standard.
Three, summary of the invention
The object of the present invention is to provide a kind of high chemical resistance pipeline epoxy corrosion protection coating, for realizing purpose, the technical scheme that the present invention adopts is:
In cast-iron pipe, evenly spray high chemical resistant pipe epoxy anti-corrosive paint; High chemical resistant pipe epoxy anti-corrosive paint is mixed by A, two kinds of components of B by weight at 1: 2, and wherein the preparation process of A, two kinds of components of B is following:
The preparation of A component is counted by weight,
Get propyl carbinol 2.56-4.06 part, YLENE 9.5-15.89 adds dispersion tank, stirs to add 5054 skimmer 0.8-1.08 parts down; Toughner 0.3-0.5 part; Add modified aliphatic solidifying agent 18.5-19.5 part after 10 minutes, high speed dispersion 30-60 minute, promptly get the product A component;
The preparation of B component is counted by weight,
Get propyl carbinol 1.2-2.68 part, YLENE 4.3-6.5 part, hexalin 1.5-2.5 part; DMF1.5-2.5 part adds dispersion tank, stirs to add epoxy resin 29.8-35.67 part down, and evenly the back adds yellow oxide of iron, white titanium pigment 7.9-9.9 part; Aerosil 0.5-0.7 part, process white 12.5-14.6 part, high speed dispersion 30 minutes; Be ground to sand mill and require fineness, promptly obtain the product B component.
C mixed A, two kinds of components of B by weight 1: 2, stir, and obtained corrosion-resistant epoxy paint.
Said modified aliphatic solidifying agent 1693; Epoxy resin is E-44; Toughner is PVB; Yellow oxide of iron, white titanium pigment, process white are not less than 500 orders; The coat-thickness of spraying is not less than 120 microns; The coating fineness is not more than 60 microns; Coating need be toasted 2 hours down at 150 ℃.
The present invention has following characteristics:
1, adopts a kind of modified aliphatic solidifying agent, made coating have extremely strong chemical resistance.Like following table 1
Each item technical feature has been passed through the authentication of the authoritative feeler mechanism of German LGA and the detection of Austrian feeler mechanism, is domestic unique coating products that obtains this mechanism's approval.Its core technology content, innovation level and cost performance are in domestic and international leading position, have filled up the blank of cast-iron pipe field aseptic technic.
2, excellent physical and mechanical properties is like following table 2
| Test item | Detected result | Detect foundation |
| Sticking power/level | 1 | GB/T1720 |
| Snappiness/mm | 1 | GB/T1731 |
| Resistance to impact shock/Kgmm | 50 | GB/T1732 |
| Hardness | 0.68 | GB/T1730 |
3, effect is good; At present; Using this technology carries out the enterprise of corrosionproof protection nearly 20 families is arranged; Anti-corrosion pipeline with this technical products spraying all exports to foreign countries, and finds a good sale in more than 20 country such as Germany, France, Britain, the U.S., Iran, Iraq, Saudi Arabia, Kuwait, Syria, Australia, India, Indonesia, Malaysia, Nepal, Korea S and Hong Kong, Taiwan, has obtained nearly 80,000,000 yuan direct economic benefit; And for domestic enterprise brings the nearly 1,000,000,000 yuan output value of foreign exchange earning, economic benefit and social benefit are very significantly.
