Abstract
The invention relates to a heavy-duty anticorrosion coating. Raw materials of the coating comprise, by weight, 20-35 parts of an epoxy resin 618, 20-35 parts of an epoxy resin 828, 5-15 parts of butyl glycidyl ether, 1-5 parts of a tertiary amine curing accelerator, 1-5 parts of a polysiloxane, 8 parts of a polyamide, and 12 parts of a modified araliphatic amine epoxy curing agent. A method for preparing the coating comprises the following steps: mixing the epoxy resin 618 with the epoxy resin 828, adding a specific filler, an assistant and the curing agent to form the heavy-duty anticorrosion coating which does not contain an organic solvent, has a high solid content, has no solvents to volatile, and has no damages to constructors during construction. The coating which can be sprayed and brushed can form a film at normal temperature, and can be very conveniently constructed, so the environmental pollution is effectively reduced; and a coat of the coating has the advantages of strong adhesion and wear resistance, excellent anticorrosion performance, and very ideal water, salt spray, acid and alkali resistances.
Description
Technical field
The present invention relates to paint field, be specifically related to a kind of heavy-duty coating.
Background technology
Metal and the concrete facilities such as all are far away, coastal waters boats and ships, naval vessel submarine, oceanographic engineering, drilling unit, port and pier, water conservancy projects, landification equipment and bridge construction, be in for a long time under water or in 100% the wet environment, its surface corrosion, attaching organism and filthy corrosion phenomenon are very serious, and the maintenance interval of oceangoing vessel generally all is once every two years.In actual condition, many metals that are difficult under water move are equipped and the concrete facility, have to let alone burn into and pollute.
And traditional heavy-duty coating, it is low to exist solids content, solvent is high, and film forming is thin, and sticking power is low, surface treatment is strict, complicated construction technique, the technical barrier such as dew point restriction is arranged, environmental pollution is serious and the life-span is short, especially during coating to carrying out strict rust cleaning in the metallic surface, require simultaneously to be coated surface drying, these all are the difficult problems that traditional heavy-duty coating is faced with for a long time.
For above-mentioned reasons, the antiseptic projects such as China's oceanographic engineering and shipping industry and petroleum and petrochemical industry, because surface treatment and application do not reach standard, the reason such as coating property is poor, annual nearly trillion the corrosion financial loss that all will produce.At present, the anticorrosion industry in China ocean is in the urgent need to a kind of ecological, environmental protective, solvent-free, solids content 100%, nontoxicity, without the dew point restriction and have high arris conservation rate, can be under water, in the severe environment of 100% humid zone rust, the long-acting heavy-duty coating that metal and concrete surface are directly constructed.
Summary of the invention
The invention reside in provides a kind of organic solvent that do not contain, and antiseptic property is good, have stronger sticking power and wear resisting property, the heavy-duty coating of constructability.
Technical scheme of the present invention is as follows:
A kind of heavy-duty coating, its raw material consists of:
618 20～35 parts of Resins, epoxy;
828 20～35 parts of Resins, epoxy;
5～15 parts of epoxy propane butyl ethers;
1～5 part of tertiary amine curing catalyst;
1～5 part of polysiloxane;
8 parts of polymeric amide;
12 parts of modification virtue fat amine epoxy curing agents;
Described umber is weight part.
As improvement, the raw material of heavy-duty coating consists of:
618 25～35 parts of Resins, epoxy;
828 15～30 parts of Resins, epoxy;
5～10 parts of epoxy propane butyl ethers;
1～5 part of tertiary amine curing catalyst;
1～5 part of polysiloxane;
1～3 part of clorafin;
1～3 part in poly carboxylic acid sodium;
8 parts of polymeric amide;
10 parts of modification virtue fat amine epoxy curing agents;
2 parts of phenolic aldehyde amine Resins, epoxy;
Described umber is weight part.
As improvement, the viscosity of described tertiary amine curing catalyst is 50-65mPa.s; The amine value of polymeric amide is 200-220 mgk0H/g; The viscosity of modification virtue fat amine epoxy curing agent is 300～600 mPa.s, and the amine value is 315～345 mgk0H/g.
As improvement, the raw material of described heavy-duty coating forms and also comprises
20～30 parts of antirust, anti-corrosive color stuffings;
5～20 parts of tinting pigments.
Wherein, the antirust, anti-corrosive color stuffing is selected from the mixture of one or more arbitrary proportions in the following material: zinc phosphate, iron mica, aluminium triphosphate, barium sulfate, ST antirusting powder, talcum powder.
Wherein, tinting pigment is selected from the mixture of one or more arbitrary proportions in the following material: iron oxide red, titanium dioxide, carbon black.
As improvement, the mean particle size of antirust, anti-corrosive color stuffing is not less than 1000 orders.
The protective system that adopts above-mentioned raw materials to produce does not add organic solvent, and solid content is high, and solvent-free volatilization is safe from harm to the workmen during construction; This coating not only can spray but also can brush, film forming at normal temperatures, and it is very convenient to construct, and an application of wet film can reach more than the 1200 μ m, reduces construction application road number, has both shortened the duration, has effectively reduced again environmental pollution; This paint coatings has stronger sticking power, wear resisting property and excellent antiseptic property, and no matter water-fast, salt spray resistance or acid-proof alkaline be all very good.
The preparation method of heavy-duty coating of the present invention is conventional preparation method, and concrete steps are:
First a certain proportion of Resins, epoxy 618, Resins, epoxy 828, epoxy propane butyl ether are packed in the stirred vessel, employed stirred vessel is conventional stirred vessel, and keeping rotating speed is that 1200r/min stirs, make it fully miscible after; Add antirust color stuffing, tinting pigment, keeping rotating speed is that 2500r/min continues to stir 0.5h, to stir resulting material joins three-roll grinder (three-roll grinder is that Changzhou east essence reaches machine works and produces, model is S150) be ground to the fineness of regulation, add again a certain amount of tertiary amine curing catalyst, polysiloxane and other auxiliary agents and carry out obtaining finished product after the miscible processing.
