Embodiment 1

[0015] Add 30 parts of linseed oil, 7 parts of 70# Feituo synthetic wax, and 10 parts of petroleum resin into the reaction kettle in sequence, start stirring at a speed of 10~20 rpm, raise the temperature to 100~110 degrees Celsius and wait until it is completely melted. Stirring speed of 30~35 rpm makes it evenly mixed. Turn off the heating and add 14 parts of sulfonate-based preservatives, 10 parts of calcium carbonate, 8 parts of methyl stearate, 9 parts of lithium-based grease, 12 parts of non-drying alkyd resin and 1,000 parts of the total amount under stirring. 2 / 10 naphthenate driers and 2 / 1000 anti-skinning agents. Wait for it to cool down to 40 degrees Celsius and turn off the stirring and discharging.

Embodiment 2

[0017] Add 40 parts of dehydrated castor oil, 7 parts of 62# fully refined paraffin wax, and 6 parts of C5 petroleum resin into the reaction kettle in sequence, start stirring at a speed of 10~20 rpm, and heat up to 100~110 degrees Celsius until completely melted Then mix it evenly at a stirring speed of 30~35 rpm. Turn off the heating and add 12 parts of sulfonate-based preservatives, 10 parts of calcium carbonate, 6 parts of methyl stearate, 9 parts of lithium-based grease, 10 parts of non-drying alkyd resin and 1,000 parts of the total amount under stirring. 2 / 10 naphthenate driers and 2 / 1000 anti-skinning agents. Wait for it to cool down to 40 degrees Celsius and turn off the stirring and discharging.

Embodiment 3

[0019] Add 30 parts of dehydrated castor oil, 10 parts of wax paste with a dropping (melting) point of 75 degrees Celsius, and 4 parts of C5 petroleum resin into the reaction kettle in turn, start stirring at a speed of 10 to 20 rpm, and heat up to 100~110 degrees Celsius until it is completely melted, and then mix it evenly at a stirring speed of 30~35 rpm. Turn off the heating and add 12 parts of sulfonate-based preservatives, 10 parts of calcium carbonate, 6 parts of methyl stearate, 9 parts of lithium-based grease, 10 parts of non-drying alkyd resin and 1,000 parts of the total amount under stirring. 2 / 10 naphthenate driers and 2 / 1000 anti-skinning agents. Wait for it to cool down to 40 degrees Celsius and turn off the stirring and discharging.

Abstract

The invention relates to all-solid environment-friendly protective paint and a preparation method thereof. The paint is prepared from the following raw materials: 10-40% of all-solid alkyd resin, 5-30% of mineral wax, 20-50% of drying oil, 5-20% of a sulfonate based preservative, 5-15% of calcium carbonate, 1-5% of fatty acid ester, 1-10% of a thickening agent, 5-20% of a petroleum resin, 0.1-0.5% of a drying agent and 0.2-0.5% of an anti-skinning agent. The preparation process for the protective paint comprises the following steps: adding drying oil, mineral wax and petroleum resin into a reaction kettle, rising the temperature to be 100-110 DEG C, stirring at the rotating speed of 10-20 rpm, and stirring at the speed of 30-35 rpm after the mixture is fully molten to uniformly mix the mixture; stopping heating, adding all-solid alkyd resin, fatty acid ester, the sulfonate based preservative, the thickening agent, the drying agent and the anti-skinning agent in sequence under the stirring condition; discharging when the temperature is reduced to be 40 DEG C. Compared with the conventional protective paint, the protective paint provided by the invention has the advantages of being free of solvent, environment-friendly, good in safety and stability, high in preservative efficiency, and the like.

Description

technical field [0001] The invention relates to a preparation and a process method of an all-solid environmental protective paint. Background technique [0002] Rusting (oxidation) is one of the basic chemical characteristics of many metals, and it will slowly occur at room temperature. From a thermodynamic point of view, metal compounds are in a low-energy state, while single metals are in a high-energy state. Corrosion is the spontaneous transformation of unstable metals into their compounds, so it can be said that corrosion is a natural tendency for most metals. [0003] Metals endure five to ten years or more as they are processed into finished products, during which time the environment can be harsh. Especially the steel materials commonly used in automobiles, once rusted, the iron oxide produced will absorb water molecules in the air, causing more serious corrosion. The anti-rust treatment of the car is mainly concentrated on the body. A body during manufacture is c...
