Embodiment 1

[0046] A kind of wax that is used for automobile inner cavity protection, it is composed of 50% Fischer-Tropsch wax adding 30% No. 80 petroleum microcrystalline wax, remaining components are 5% calcium stearate, 1% triethanolamine, 0.4% sulfonate, 1.6% benzotriazole fatty amine salt, 2% ethylene propylene resin, 10% EVA resin. Fischer-Tropsch wax has a melting point of 95°C and a n-paraffin content of over 95%. The anti-rust wax has low temperature resistance at -20°C, high temperature resistance at 90°C, no deformation and flow at 75°C, and an anti-rust time of 6 over a month. And has good surface smoothness, anti-wear performance and anti-peeling properties. It can resist the impact of normal road stones.

Embodiment 2

[0048] A surface protection and antirust wax for precision instruments, which consists of 50% Fischer-Tropsch wax, adding 30% isomerized wax modified by hydroisomerization of Fischer-Tropsch wax, adding 5% polyethylene wax, The remaining components are 0.8% calcium petroleum sulfonate, 0.8% tetradecenyl succinate tetradecylamine, 1.4% benzotriazole fatty amine salt, and 12% EVA resin. Fischer-Tropsch wax component is C 45 ~C 95 Alkanes, the melting point is 108°C, and the normal alkanes content is above 95%. The hydroisomerization modified wax has an average molecular weight of 1500 and a methyl content of 12% by weight. The anti-rust wax can form a smooth and tough coating on the surface of the instrument, and has a good anti-rust effect.

Embodiment 3

[0050] A kind of anti-rust wax for ordinary steel, its composition is 55% Fischer-Tropsch wax, add 25% of No. 64 semi-refined petroleum wax, add 10% of No. 80 petroleum microcrystalline wax, and the remaining components are 1.5% Triethanolamine, 0.5% petroleum sulfonate, 3% ethylene propylene resin, 5% EVA resin. Fischer-Tropsch wax is C 33 ~C 50 Alkanes with a melting point of 80°C and a n-paraffin content of over 90%. The antirust wax has low temperature resistance at -10°C, high temperature resistance at 80°C, no deformation and flow at 68°C, and an antirust time of 6 over a month.

Abstract

The invention relates to an antirust wax, which takes Fischer-Tropsch synthesis wax as a matrix material, and is composed by adding a polymer, petroleum wax, an antirust agent, a filling material and the like. The components with weight percentage are 10wt%-80wt% of Fischer-Tropsch wax, 2wt%-30wt% of polymer, 0-40wt% of petroleum wax, 0.1wt%-10wt% of antirust agent and 0-20wt% of filling material. The antirust wax is convenient to use, and has good antirust performance, excellent surface smoothness and abrasion resisting performance, good fluidity and flexing resistance, impact resistance and antistripping resistance. The antirust wax possesses wide application, and can be used for moisture resistance and corrosion resistance of various steels, precision apparatus, casting members, processing parts(such as automobile chassis, large-scale bearing and the like), and can be used for antirust processing schemes with low cost. The antirust wax can be directly heated for coating, can be prepared to liquid by adding a volatile solvent, and can be prepared to an emulsifier by adding water for emulsification.

Description

technical field [0001] The invention relates to an anti-rust wax, which is suitable for moisture-proof and anti-corrosion of the surfaces and inner cavities of various steel materials, precision instruments, castings and processed parts, etc., as well as sewer pipes, factory sewage discharge pipes and ship docks Low-cost anti-rust treatment such as anti-salt spray corrosion; the present invention also relates to the use and method of the anti-rust wax. Background technique [0002] Iron and steel metals (such as steel, automobiles and castings, etc.) are easy to rust due to environmental and other factors under natural storage conditions, thereby reducing or losing their use value, causing safety accidents and economic losses. The amount of direct economic loss caused by metal corrosion in our country is huge every year. [0003] Metal corrosion is mainly divided into chemical corrosion and electrochemical corrosion from the mechanism. There are many reasons for corrosion,...
