Abstract
The invention discloses wear-resisting iron oxide red anticorrosive paint. According to the wear-resisting iron oxide red anticorrosive paint, modified isolated soybean protein meal is added into raw materials by serving as an adhesive, and therefore the cohesiveness and the affinity of the paint with a polymer are improved; nano-silicon dioxide and ultrafine iron oxide red powder are mixed to be uniform and then subjected to organic modification, on one hand, the surface of the iron oxide red powder is organized, the lipophilicity and the compatibility of the paint with organic matter are improved, therefore, the phenomenon that the ultrafine iron oxide red powder is prone to agglomeration is prevented, and the water resistance and the corrosion resistance of the paint are improved, and on the other hand, an inorganic SiO2 network of modified nano-silicon dioxide and a polymer chain form a mutually-crosslinked interpenetrated structure, motion of the polymer molecular chain is inhibited, and the heat resistance of the paint is improved. The prepared paint is good in adhesive force, capable of resisting wearing, water and alkali, long-acting and durable, convenient to construct, simple in preparation method and capable of easily achieving large-scale production.
Description
Technical field
The present invention relates to technical field of coatings, particularly relate to a kind of wear-resisting iron oxide red anticorrosive paint and preparation method thereof.
Background technology
Development along with China's modern industry, particularly in industries such as metallurgy, petrochemical industry, the energy, new material and military projects, the application of high-temperature service and auxiliary facility gets more and more, metal material oxygen generation oxidation reaction easily and in air in hot environment, produce corrosion phenomena, make metal material gradually lose intensity and cause structural disappearance, become the hidden danger of various accident.Therefore, high-temperature service surface the most all needs application fire-resistant anticorrosion paint to protect, and to prevent metal material oxide etch, extends the service life of high-temperature service.
Iron oxide red is also referred to as become rusty red, red oxidization iron powder, because of it is nontoxic, chemical stability is good and have excellence fast light, high temperature resistant, acidproof, alkaline-resisting, antirust, the advantages such as ultraviolet can be absorbed and become usage amount and be only second to the second largest inorganic pigment of titanium dioxide.Iron oxide red is largely used to antirusting paint and has physical property antirust function, and moisture in air etc. is impermeable in metal level, and can increase compactness and the mechanical strength of coating.
Epoxy resin has excellent adhesion, wearability, electrical insulating property, resistant of high or low temperature, chemical proofing, have that adhesive force is good simultaneously, good mechanical performance and shrinkage factor machine-shaping low, easy and the advantage such as with low cost, be the good material as anti-corrosion of metal erosion resisting coating.But in tridimensional network after pure epoxy resin solidification, crosslink density is high, the problem such as have that internal stress is relatively big, quality is the most crisp, resistance to cracking is poor, resistance to impact is strong and wet-heat resisting is the best.
" preparation of new type silica sol modified epoxy composite coating and performance evaluation " prepares amino modified Ludox by sol-gel process, and by its mixing modification epoxy resin to obtain silica sol modified epoxy composite coating.Result shows: when add improved silica Ludox account for epoxy resin content be 2%-5% time, the adhesive force of coating, hardness, resistance to impact, pliability etc. are preferable, and the gasoline acidproof, alkaline-resisting, resistance to of coating, resistance to distilled water, salt water resistance effect also reach actually used standard simultaneously.Silicon dioxide and alternate chemical bond and the hydrogen bond action of existing of epoxy resin two in hybrid coating, the result of hybrid inorganic-organic crosslinking, can improve the high temperature resistant of coating and Corrosion Protection.
Although but iron oxide red superfine powder body has the advantages such as granularity is little, specific surface area is big, surface activity is strong, chemical reaction velocity is fast in literary composition, but it has thermodynamic phase simultaneously, easily reunite, so that application performance is severely impacted, so we need to improve the dispersive property of superfine iron oxide Hydrargyri Oxydum Rubrum body；Binding agent commonly used in the prior art is organic or inorganic class Chemical Felter mostly, to have coated the most of long duration easy to fall off but also there is corrosion metal and pollutes the hidden danger of environment, the present invention also needs to be improved existing coating binding agent, optimizes existing production technology and formula proportion and then prepares the iron oxide red anticorrosive paint of Multifunctional environment friendly.
