Abstract

The present invention is a kind of prescription and manufacturing of anti-corrosive and waterproof paint, and its prescription is formed (weight %) and is: 30-50 coal-tar pitch, 2-5 carbolineum, 2-5 talcum powder, the 2-6 mica powder, 2-12 polystyrene, 1-2 wilkinite, 0.2-1.0 tung oil, 0.3-10 isocyanic ester (PAPI), 30-50 toluene.This coating manufacturing course is easy, with low cost, functional, easy construction, and envrionment conditions is less demanding, is a kind of anti-corrosive and waterproof paint of ideal economy.

Description

A kind of prescription of anti-corrosive and waterproof paint and manufacturing

The present invention is a kind of prescription and manufacturing of anti-corrosive and waterproof paint.Belong to the chemical paint class.Use this coating can protect structures such as iron and steel, timber, cement for a long time, exempt from the etch of water, acid, alkali, salt etc.

Anticorrosion, waterproof paint at present both domestic and external mainly contains petroleum pitch, coal-tar pitch, epoxide coal bituminous, plastics jacket, plastic tape, cementing powdered epoxy coating etc.Though petroleum pitch and coal-tar pitch price are lower, the construction requirement heating boils the liquid construction down more than 200 ℃, and operational condition is abominable, and environmental pollution is serious, and coating machine intensity is low, easily is mechanically damaged in the construction.Epoxide coal bituminous and plastic tape can be constructed under cold conditions, but costs an arm and a leg, and cost is too high; Plastics jacket and cementing powdered epoxy coating price are higher, and this coating can not site operation, and complex process requires the envrionment conditions harshness.It as U.S.'s patent granted on December 24th, 1979 number is 4304706 patent " preparation moisture cure urethanes lacquer method ", the invention people is Bhashav Rurs, this lacquer is simple urethane, do not add plastics, though it can single component be constructed, but require condition harshnesses such as temperature, humidity, cost is also high.

In order to overcome the deficiency of above-mentioned various anti-corrosive and waterproof paints, by the years construction experience, the contriver proposes new formulation for coating material and manufacturing course, and has repeatedly carried out scientific experimentation, has solved the problems referred to above, thereby proposes the present invention.

The present invention is a kind of composition and manufacture method of novel anti-corrosive and waterproof paint.It contains coal-tar pitch, solvent, additive and filler, it is characterized in that its composition (weight %), be that coal-tar pitch is 30～50, carbolineum is 2～5, and talcum powder is 2～5, mica powder is 2～6, polystyrene is 2～12, and wilkinite is 1～2, and tung oil is 0.2～1.0, isocyanic ester (PAPI) is 0.3～10, and toluene is 30～50.Wherein compatibility is good mutually between polystyrene and the coal-tar pitch; Polystyrene obtains a tough and tensile preservative coat after making the coating drying therein; The effect of the isocyanic ester (PAPI) during this invention is formed is that coating is met tide when coating brushing during at structure things such as underground pipeline or walls, and isocyanic ester (PAPI) decomposition autohemagglutination makes it to form one deck hard coat, reaches anticorrosion waterproof purpose; This coating contains tung oil, and tung oil runs into air oxidation immediately, thereby strengthens paint solidification, strengthens mechanical property.It should be noted that especially this invention can make full use of waste and old polystyrene plastic, causes cost to reduce greatly.Solvent is a toluene in the present invention, and it is tung oil, isocyanic ester (PAPI), carbolineum that lacquer adds agent, and filler is talcum powder, mica powder, wilkinite etc.

The manufacturing course of this coating is as follows: at first get its carbolineum by the per-cent number of forming regulation, the heating of this carbolineum is boiled when temperature is 100～150 ℃, the coal-tar pitch that adds the percentage composition regulation, stirring heating in heating kettle, coal-tar pitch is melted, after treating to melt fully, filter with 150 mesh sieves, carbolineum coal-tar pitch mixture after the filtration is cooled to normal temperature, add an amount of toluene then, stir, in this, add the mica powder of forming specified quantity again, talcum powder, fillers such as wilkinite, after stirring, add the polystyrene toluene solution, tung oil, its polystyrene and tung oil quantity are by the quantity separately of forming regulation, and twice adds toluene quantity sum for forming the toluene quantity of regulation.They are stirred, and after grinding makes particle fineness less than 80 μ, add the isocyanic ester (PAPI) of forming regulation, stir.

This dope viscosity is 80～160 seconds, and fineness is less than 80 μ.

Once be coal-tar pitch 38 with following composition, carbolineum 3, talcum powder 3, mica powder 3.4, polystyrene 6.5, wilkinite 1.5, tung oil 0.6, isocyanic ester (PAPI) 3, the coating that toluene solvant 41 is made, constructed by the exploration Fifth Academy of Aerospace Industry of weapons portion in the top, 218 oil depot cavern holes in the Capital Airport, unit in charge of construction and applying unit reflection are good.The results showed, this coating and petroleum pitch coating now commonly used relatively, paint adhesion power of the present invention is big, the physical strength height, anti-microbial attack, water-intake rate is low, can coldly down be coated with construction at-15 ℃, can construct on the wet cement face, and is convenient handy.Compare with epoxide coal bituminous, paint coatings good toughness, but single-component construction, price is low; Epoxide coal bituminous then is two component constructions, needs on-the-spot preparation, and wayward, and price is also high.Compare with chlorosulfonated polyethylene, coating amount of solid content height of the present invention, coating is little close, and corrosion-resistanting waterproofing performance is good, the brushing number of times is few, and labor and material saving reaches effect same, and price is lower by 20%～40% than it, with the plastics jacket, plastic tape is compared, but the hand construction, price low 50%～80%.

In a word, the present invention can make full use of junk, and cost is low, and manufacturing process is easy, and corrosion-resistanting waterproofing performance is good, firm and durable, and saving of work and time, envrionment conditions is less demanding, and easy construction is cheap, is a kind of ideal anti-corrosive and waterproof paint.

Claims
