AI Technical Summary

Problems solved by technology

At present, there are few types of peelable paints used in the market, and the corrosion resistance of the products is average. The coating has blistering and peeling phenomena, which cannot well protect the non-processed metal surface under the layer from erosion, and the erosion ratio cannot meet user requirements.

Embodiment 1

[0032] 1. Rubber mixing:

[0033] ① Warm 5g of LDJ-230 neoprene rubber and 10g of neoprene US W type in a greenhouse at 40-50°C for 10 hours, cut them into small pieces with a rubber cutter, and place the cut rubber pieces at the roller pitch while they are soft. Roll the material on the 1mm rubber mixer, turn on enough cooling water, and then adjust the roll pitch to 0.5mm. Put the above-mentioned rolled rubber on the rubber mixer to soften it for 2-3 times, and then adjust the roll pitch to 0.1-0.2 mm to continue rolling 15-20 times to improve the plasticity of the rubber; ②Adjust the roll pitch to 1mm, add 1g of magnesium oxide, 0.1g of anti-aging agent, 0.1g of stearic acid, 0.5g of zinc oxide, and then roll the rubber. Adjust the roll pitch to 0.1-0.2mm and continue rolling the material 10 times to make the added raw materials evenly dispersed. The dispersion of each material is tested by tearing the rubber compound into a film, and it is uniform and transparent. No raw mate...

[0038] 1. Rubber mixing:

[0039] ① Warm 20g of butadiene rubber in a greenhouse at 40-50℃ for 10 hours, cut it into small pieces with a rubber cutter, and place the cut rubber pieces on a rubber mixer with a roller pitch of 1mm while they are soft. Water, and then adjust the roll distance to 0.5mm, put the above-mentioned rolled rubber on the rubber mixing machine through 2-3 times of softening, and then adjust the roll distance to 0.1-0.2mm and continue rolling 15-20 times to improve Plasticity of the rubber; ②Adjust the roll pitch to 1mm, add 3g of magnesium oxide, 0.5g of anti-aging agent, 0.5g of stearic acid, and 1g of zinc oxide to roll the rubber, then adjust the roll pitch to 0.1-0.2mm and continue rolling 10 Second, make the added raw materials uniformly dispersed. The dispersion of each material is tested by tearing the rubber compound into a film. It is uniform and transparent. If there is no raw material particles, it is qualified. Adjust the roll distance to 1mm and...

[0044] 1. Rubber mixing:

[0045] ① Warm 10g of styrene butadiene rubber and 8g of nitrile butadiene rubber in a greenhouse at 40-50℃ for 10h, cut them into small pieces with a rubber cutter, and place the cut rubber pieces on a rubber mixer with a roller pitch of 1mm while they are soft. Turn on the cooling water, then adjust the roll pitch to 0.5mm, put the above-mentioned rolled rubber on the rubber mixing machine through 2-3 times of softening, and then adjust the roll pitch to 0.1-0.2mm to continue rolling 15- 20 times to improve the plasticity of the glue; ②Adjust the roll pitch to 1mm, add 2g magnesium oxide, 0.3g anti-aging agent, 0.3g stearic acid, and 2g zinc oxide to roll the glue, then adjust the roll pitch to 0.1-0.2 mm continues to roll the material 10 times to disperse the added raw materials evenly. The dispersion of each material is tested by tearing the rubber compound into a film, and it is uniform and transparent. If there is no raw material particles, it is q...

Abstract

The invention relates to a rubber peelable paint and a preparation method thereof, which is characterized in that it comprises the following components: rubber 10-25, magnesium oxide 1-3, anti-aging agent butyl 0.1-0.5, stearic acid 0.1-0.5, zinc oxide 0.5-2, carbon black 3-6, toluene 50-65, 50% pure phenolic resin solution 5-10, self-made perchlorethylene anticorrosive varnish 10-20. Rubber mixing; preparation of black slurry; preparation of glue solution; paint making: add rubber solution and black slurry to the paint mixing tank, stir for 1 hour, and adjust the viscosity with the remaining 10% toluene. Beneficial effect: the rubber is modified by self-made perchlorethylene anti-corrosion varnish and 50% pure phenolic resin solution to prepare rubber peelable paint, the paint film is strong and tough, has excellent alkali resistance and acid resistance, good corrosion ratio, and is easy to Stripped and trimmed neatly. Mainly used for temporary protection of chemical milling aluminum alloy.

Description

Technical field [0001] The invention belongs to paint, and particularly relates to a rubber peelable paint and a preparation method thereof. Background technique [0002] Aluminum alloy thick plates need to be milled and engraved according to design requirements, and the surface patterns of many aluminum alloy parts are processed by acid or alkali corrosion. For milling aluminum alloys that require fine processing, a temporary protective coating should be sprayed on the surface to prevent the non-machined surface under the paint film protective layer from being corroded, that is, the aluminum alloy of the non-machined surface must be well preserved and wait for acid or alkali corrosion Later, after peeling off the paint film, the processed surface of the substrate reaches the designed corrosion depth and the corrosion ratio meets the design requirements. At present, there are few types of peelable paints on the market, and the products have general corrosion resistance. The coat...
