Embodiment 1

[0125] Example 1. Magnesium Potassium Phosphate Composition

[0126] In this experiment, the first (acidic) component consisted of monopotassium phosphate (MKP) having a pH value of about 4.2 when measured in aqueous solution. The MKP was milled for one hour to about 74 micron size powder (US 200 sieve) before use. The MPK was then further milled for one hour and its pH was adjusted between 3.2 and 3.5 by adding 2.5% by weight phosphoric acid (added as a 50% dilute solution). 0.5% by weight copper oxide was added to prevent algae growth. The solution was adjusted with water to produce a viscosity of approximately 10,000 centipoise. The component has a density of 1.9 g / cm 3 .

[0127] The second component (basic) was prepared as follows: The required amount of magnesium brine solution (Martin Marietta) as a source of magnesium hydroxide was weighed into a mixer. Zr(OH) 4 The powder was added to the brine and stirred for 5-10 minutes until homogeneous. Wollastonite passin...

Embodiment 2

[0137] Example 2. Aluminum Phosphate Composition

[0138] 30g aluminum hydroxide (gibbsite, Al(OH) 3 ) was added to 173.4g phosphoric acid solution (H 3 PO 4 , 50% by weight, molar ratio Al(OH) 3 :H 3 PO 4 =1:2.3). 1.5 g (5% by weight) of potassium fluoride and 1.5 g of potassium permanganate were added to the Al(OH) 3 in the acid together. The mixture is stirred at 100-110°C for 60 minutes to about 3 hours. The product obtained after cooling to room temperature was a viscous slurry. This is labeled Component A.

[0139] Potassium permanganate as an exemplary oxidizing agent was added as an optional reagent to reduce hydrogen gas formation in Example 2. The use of an oxidizing agent provides improved adhesion to surfaces such as steel / iron surfaces. The results of the coating of the composition of Example 2 on the steel / substrate provided improved adhesion between the inorganic phosphate composition and the metal compared to its adhesion in the absence of an oxidizi...

Embodiment 3

[0146] Example 3: Method of Forming a Phosphorite Coating

[0147] Theoretical analysis based on thermodynamic principles shows that aluminum trihydrogen phosphate, if combined with alumina (corundum, Al 2 o 3 ) reaction, aluminum phosphate (AlPO 4 ) (block phosphate aluminite). The azophosphate mineral phase, which is stable up to 1500°C, will provide high temperature coatings. Therefore, 100 grams of aluminum trihydrogen phosphate (AlH 3 (PO 4 ) 2 -5H 2 O) Viscous slurry was mixed with 50 grams of alumina fine powder and mixed well to form a viscous slurry. Brush it on a mild steel substrate preheated at 175°C. First, some of the water of the slurry partially evaporates, but then the coating bonds well to the steel. The entire assembly was maintained at 175°C for about three hours. Once all outgassing and evaporation had occurred, the second coating was applied and set at 175°C for about three hours. The resulting thick coating formed on the steel surface is hard,...

Abstract

Disclosed and described are multi-component inorganic phosphate formulations of acidic phosphate components and basic oxide/hydroxide components. Also disclosed are high solids, atomizable compositions of same, suitable for spray coating.

Description

technical field [0001] This invention relates to multicomponent inorganic phosphate preparations of an acidic phosphate component and a basic oxide / hydroxide component. Background technique [0002] Organic synthetic materials made from epoxy, polyester, polypropylene, and other polymers are widely used in composite materials such as fiberboard, fiberglass composites, sealants for marble and granite countertop surfaces, aircraft, body armor, etc. . These resins are relatively expensive, have high greenhouse gas densities and are flammable. The volatile organic compounds released by them during their use present a health hazard for users. [0003] Techniques exist for formulating inorganic mineral-based resins but these techniques are generally based on alkali metal aluminosilicates and alkali metal boroaluminosilicates. These techniques are mostly limited to one type of article and do not always allow the manufacture of resins with a wide range of formulations, properties...
