Embodiment 1

[0024] Put 600kg of linseed oil and 140kg of tung oil into the reaction kettle, stir and raise the temperature to 280°C-290°C, and then keep it warm until the viscosity reaches -4 cups 150-160s / (25±2)°C. Cool down to 260°C-270°C, add 110kg of rosin, reheat, and keep warm at 280°C until the viscosity is Tu-4 cups 300-320s / (25±2)°C. Then cool down to 260°C, dilute with 90kg of turpentine out of the kettle to reach the required viscosity: Tu-4 cups 180-200s / (25±2)°C. After filtering to reach a fineness of ≤30um, put it into the tank for inspection.

[0025] Get natural resin 580kg, titanium dioxide 80kg, fineness is 325 purpose superfine calcium carbonate 100kg, turpentine 150kg. Put 300kg of natural resin into the material pot, add 80kg of titanium dioxide, 100kg of superfine calcium carbonate, and then add 100kg of turpentine for grinding for 40-60 minutes. The grinding time depends on the required paint fineness. After the remaining 280kg of natural resin and 50kg of turpenti...

Embodiment 2

[0027] Put 624kg of raw material linseed oil and 156kg of tung oil into the reaction kettle, stir and raise the temperature to 280°C-290°C, and then keep it warm until the viscosity reaches Tu-4 cup 150-160s / (25±2)°C. After cooling down to 260°C-270°C, add 120kg of rosin, reheat, and continue to keep warm at 280°C until the viscosity is coated with -4 cups 300-320s / (25±2)°C. Then cool down to 260°C, and use 100kg of turpentine for the kettle. Dilute to reach the required viscosity and apply -4 cups 180-200 / (25±2)℃. After being filtered to reach a fineness of ≤35um, it is inspected and put into the tank for later use.

[0028] Get 600kg natural resin, organic medium yellow 100kg, fineness is 325 purpose superfine calcium carbonate 125kg, turpentine 175kg. Put 400kg of natural resin into the material pot, add 100kg of organic medium yellow, 125kg of superfine calcium carbonate, and then add 100kg of turpentine to grind for 40-60 minutes. The grinding time depends on the require...

Embodiment 3

[0030] Put 630kg of linseed oil and 145kg of tung oil into the reaction kettle, stir and raise the temperature to 280°C-290°C, and then keep it warm until the viscosity reaches Tu-4 cup 150-160s / (25±2)°C. After cooling down to 260°C-270°C, add 130kg of rosin, reheat, and keep warm at 280°C until the viscosity is coated with -4 cups of 300-320s / (25±2)°C. Then cool down to 260°C, and use 95kg of turpentine for the kettle. Dilute to reach the required viscosity and apply -4 cups 180-200 / (25±2)℃. After being filtered to reach a fineness of ≤35um, it is inspected and put into the tank for later use.

[0031] Get 600kg natural resin, phthalocyanine blue 100kg, fineness is 325 purpose superfine calcium carbonate 125kg, turpentine 175kg. Put 400kg of natural resin into the pot, add 100kg of phthalocyanine blue, 125kg of superfine calcium carbonate, and then add 100kg of turpentine to grind for 40-60 minutes. The grinding time depends on the required paint fineness. The remaining 200...

Abstract

The invention relates to a manufacturing method of a steel structure paint thinner (polyurethane type). The steel structure paint thinner (polyurethane type) is mainly prepared from waterproof paint, phosphide paint, a pigment, a thinner and a filler, wherein the thinner is a natural plant solvent refined from plant juice, and the pigment is a natural pigment or a pigment processed from natural matters. All components of the steel structure paint thinner (polyurethane type) disclosed by the invention have no toxic chemical solvents, such as benzene, methylbenzene and the like, and the steel structure paint thinner (polyurethane type) further has the advantages of appropriate amount of mercury, aluminum, cadmium, lead and other heavy metal ions, no irritant odor, no volatilization of fluoric acid ester toxic gas, healthy and environment-friendly properties, excellent performance, simple construction and wide range of application.

Description

technical field [0001] The invention belongs to the field of diluents, and in particular relates to a method for preparing steel structure paint diluents (polyurethane). Background technique [0002] Most chemically synthesized paints contain benzene, formaldehyde, heavy metals, etc. Extensive use will cause air and land pollution and air quality degradation, and have a serious impact on people's living environment and physical health. With the strengthening of the society's awareness of the environment, people pay more and more attention to the living environment. In order to limit the pollution of harmful substances to the human ecological environment, the Chinese government issued GB18581-2001 "Limits of Harmful Substances in Solvent-based Wood Coatings for Interior Decoration Materials" , GB18582-2001 "Limits of Harmful Substances in Interior Decoration Materials and Interior Wall Coatings" and other national standards. The formulation of the standard has limited and re...
