Abstract
The invention discloses zinc-rich paint with addition of isopropyl tri (dioctyl phosphate acyloxy) titanate and a preparation method thereof. According to the zinc-rich paint with the addition of the isopropyl tri (dioctyl phosphate acyloxy) titanate, through the addition of an isopropyl tri (dioctyl phosphate acyloxy) titanate coupling agent, not only is the adhesive force of the paint improved greatly, but also the effects of preventing sedimentation and improving the mechanical strength of the composite material can be effectively achieved.
Description
Technical field
The present invention relates to a kind of protective system, particularly a kind of zinc-rich paint adding titanate coupling agent, belongs to paint field.
Background technology
Along with the development of metal industry, the use of metal is more and more general, and all use metallic substance everywhere in life, as automotive industry, production, construction industry, transportation, in life, all trades and professions all use metallic substance.In metallic substance, iron and steel uses the most extensive, and within 2014, global crude steel output reaches 16.62 hundred million tons, increases by 1.2% on a year-on-year basis.Wherein Chinese crude steel output reaches 8.227 hundred million tons, and steel are mainly used in inside structured material, heavy construction and big machinery.Iron and steel easily corrodes when using, and during corrosion, the interface of metal there occurs chemistry or electrochemistry heterogeneous reaction, makes metal proceed to oxidation (ion) state.This significantly can reduce the mechanical property such as intensity, plasticity, toughness of ferrous materials, destroys the geometrical shape of hardware, shortens the work-ing life of equipment, even cause the catastrophic failure such as fire, blast.People delay the corrosion speed of iron and steel by various mode, as improved base material, selecting anticorrosive, increase metal plating, adding inhibiter etc.By add other materials to suppress in pure metal or stop the corrosion shortcoming of iron and steel to be compared with original material, its physicals often lacks to some extent, or cause cost to increase due to the cost of alloy.Therefore the most frequently used anti-corrosion mode is exactly to needing the additional top coat having a tolerance of the metal of protection.Coating is one of important channel of anticorrosion of steel structure, and zinc rich primer is one of most widely used basic silkworm race in protective system.
Zinc-rich paint is divided into organic zinc rich paint and inorganic zinc coating, and it is film forming binder that organic zinc-rich paint commonly uses epoxy resin, chlorinated rubber, Vinylite and urethane resin.But the poor electric conductivity of the organic binder of organic zinc-rich paint.Inorganic zinc coating is divided into again solvent-borne type and water-based two class.Wherein aqueous inorganic zinc-enriched coating is made up of aqueous inorganic silicate (receive, potassium, lithium) resin, zinc powder, auxiliary agent etc.In water-borne coatings, because solvent is few, wettability is low, and thus sticking power is good not as corresponding solvent based coating.
Titanate coupling agent can form bridged bond with polymkeric substance and inorganic ground, due to the polar group that induces one in coupling agent (as epoxide group), improve with ground affinity, thus sticking power significantly improves, therefore in zinc-rich paint, add the sticking power that titanate coupling agent can improve coating, and also can make the corresponding enhancing of other performance while improving for a certain performance.The preparation of titanate coupling agent has very highland handiness, and compared with its corresponding auxiliary agent, cost performance is excellent.The present invention, by preparing in zinc-rich paint process, adds a kind of titanate coupling agent mixture, prepares a kind of zinc-rich paint of sticking power excellence.Sec.-propyl three (dioctyl phosphoric acid acyloxy) titanic acid ester is added in coating, not only increases sticking power but also effectively can play effect that the is anti-settling and physical strength of raising matrix material.
Summary of the invention
The present invention open a kind of interpolation sec.-propyl three (dioctyl phosphoric acid acyloxy) titanic acid ester zinc-rich paint and preparation technology thereof, contained by this coating, the mass percent of component is:
Potassium silicate 10%-20%;
Gui Suan Na 10%-20%;
Super-fine zinc dust 40%-60%;
Organosilicon crylic acid latex 15%-30%;
Sec.-propyl three (dioctyl phosphoric acid acyloxy) titanic acid ester 3%-10%;
Dilute phosphoric acid 2-10%.
A kind of preparation method adding sec.-propyl three (dioctyl phosphoric acid acyloxy) titanic acid ester zinc-rich paint comprises the steps:
(1) get a container, potassium silicate solution and Gui Suan Na solution are poured in container, mixes and heat;
Again by a certain amount of organosilicon crylic acid latex slowly in container, and ceaselessly to stir;
(3) stop heating, then in container, add a certain amount of sec.-propyl three (dioctyl phosphoric acid acyloxy) titanic acid ester, high-speed stirring;
(4) add zinc powder, ceaselessly stir;
(5) the dilute phosphoric acid that last interpolation is appropriate, obtains a kind of interpolation sec.-propyl three (dioctyl phosphoric acid acyloxy) titanic acid ester zinc-rich paint.
Preferentially, step (1) in, Heating temperature is 70-80 DEG C.
The present invention has following advantages and characteristic:
(1) this Paint preparation technology is simple, good operability;
The result of prevention of coating and physical strength better.
