Not only work in strong corrosive environment, while again because of continuous movement, bear washing away and growing for the media such as water flow air-flow sandstone
Influence service life is seriously worn so as to cause material in the abrasion of phase mechanicals efforts.
Wear-resistant paint has become the core in new coating field as the functional coating for solving coating wear-resistant protection scheme
One of heart, in global coatings industry technical field of research, the coating of wear-resisting functions accounts for 25-35%, it has also become countries in the world are novel
The emphasis of paint field research and development.
Epoxy resin refers in molecular structure containing two or more epoxy groups, with aliphatic, alicyclic or fragrant
The organic compounds such as race are skeleton and can react the change to form three-dimensional cross-linked netted thermoset products with curing agent by epoxy group
Close object general name.As a kind of universal thermosetting resin, have the characteristics that storage stability is high, while its solidfied material is with excellent
Bonding force and mechanical strength, while there are also chemical-resistant, alkali resistance and corrosion resistance and be widely used as coating material.But
Since epoxy resin forms highly cross-linked 3 D stereo reticular structure in the curing process, molecule interchain lacks sliding, causes
Make that solidified resin internal stress is larger, property is crisp, extensibility is low, is also easy to produce crackle, therefore is unable to satisfy with its wear-resistant paint prepared
Toughness and wear-resisting demand.The study on the modification of epoxy resin, Zhang Wei are made to improve coating wearability and toughness, a large amount of scholars
Et al. use base polyurethane prepolymer for use as epoxy resin is modified, by inside system formed " island configuration ", make rigidity
Distribution elastic polyurethane group improves toughness in epoxy construction；Slowly the ZW-10 self-lubricating type ceramic wear-resisting heavy antisepsis of medium research
Coating is the normal temperature solidified two-component coating using ceramic powders as filler, which has high-wearing feature and excellent anti-corrosion
Property；Liu Yan etc. prepares polyurethane, acrylic resin and acrylic acid modified polyurethane coating with castor oil modified TDI, and to two sulphur
The dosage for changing the wear resistant fillers such as molybdenum, chromium oxide and polytetrafluoroethylene (PTFE) is optimized, and coating obtained has polyurethane and third concurrently
The two-fold advantage of olefin(e) acid resin, and there is excellent wearability and chemical-resistant.However, the above research is in the tough of final coating
Again without perfectly being solved in property and wearability, for certain extreme environments such as some military projects coating performance still
It is difficult to meet the requirements.Moreover, so far, making pottery for using carboxyl end group butadiene-styrene rubber Modified phenolic epoxy resin and being used cooperatively
The coating for the super abrasive filler that porcelain micro mist obtains has not been reported.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of modified super abrasive coating, with excellent toughness and resistance to
Mill property.
To achieve the above object, the present invention is achieved through the following technical solutions:
A kind of modified super abrasive coating, which is characterized in that its raw material includes: 25-35 parts of modified epoxy by weight, and amine is solid
10-20 parts of agent, 20-30 parts of super abrasive filler, 20-30 parts of common fillers, 4-8 parts of auxiliary agent.
As a preferred option, above-mentioned modified epoxy is the epoxy group of novolac epoxy resin and the carboxylic of butadiene-styrene rubber
Base occurs esterification and is prepared, and the mass ratio of novolac epoxy resin and butadiene-styrene rubber is 6:9.
As a preferred option, above-mentioned butadiene-styrene rubber is the carboxylic styrene-butadiene rubber for being acrylic monomers insertion, acrylic acid
Monomer is acrylic or methacrylic acid.
As a preferred option, above-mentioned novolac epoxy resin is bisphenol A epoxide resin.
As a preferred option, above-mentioned super abrasive filler is silicon carbide ceramics micro mist.
Using above-mentioned preferred embodiment, Wear Resistance of Coating can be further improved.
As a preferred option, above-mentioned amine hardener is modified aliphatic amine hardener.
Using above-mentioned preferred embodiment, the solid content of coating can be improved in this way and reduced volatile organic content.
As a preferred option, above-mentioned auxiliary agent, raw material include: 1-2 parts of mill base by weight, 1 part of anti-settling agent, are dispersed
0.5 part of agent, 0.5 part of defoaming agent, 1-2 parts of organosilicon auxiliary agent.
Using above-mentioned preferred embodiment, the coefficient of friction of coating surface further reduced, improve wear-resisting property.
As a preferred option, above-mentioned common fillers, raw material are 10-20 parts of titanium dioxide by weight, talcum powder 10-
15 parts.
As a preferred option, above-mentioned modified epoxy viscosity is lower than 800cps.
Beneficial effects of the present invention: a kind of super abrasive coating provided by the invention, using carboxylic styrene-butadiene rubber modified phenolic
Epoxy resin is simultaneously used cooperatively silicon carbide ceramics micro mist as super abrasive filler, compared with prior art, has excellent toughness
And wearability, room temperature rapid curing, super abrasive, low surface friction coefficient, having the characteristics that can working at ultra-low temperature.It solves one
Under a little extreme environments the problem of the flexibility and wearability of paint film, it can be used, for example, as the ground shield of naval's ice breaker, thunder
Up to the anti-corrosion of pedestal, the solution of a high-end applications is provided for military project and extra large dress system.
Specific embodiment
Below by specific embodiment, the present invention is described further.Modified epoxy the preparation method is as follows:
