preparation example Construction

[0020] The preparation method that the antirust masterbatch that is suitable for multiple metal surfaces and its coated coating in the following examples adopts, the steps are as follows:

[0021] 1) Pour the antirust agent, carrier plastic and additives into a plastic high-speed mixer according to the weight ratio and mix at high speed for 4 to 15 minutes to obtain a mixture;

[0022] 2) The obtained mixture is kneaded and melted by a double-rotor continuous kneading and granulating machine, and then kneaded and plasticized and extruded at a temperature of 150~180°C to obtain a product suitable for various metal surfaces and Its coating protects against rust masterbatch.

Embodiment 1

[0024] Antirust masterbatch 1 suitable for various metal surfaces and their coatings, wherein the weight ratio of each component is 45% antirust agent, 45% carrier plastic and 10% additive. Among them, the antirust agent is prepared by mixing imidazole acetate, 1H-1,2,4-triazole, and sodium molybdate in a weight ratio of 1:1:3, and the particle size of the antirust agent is 900-1100 mesh. The carrier plastic is high pressure low density polyethylene 1C7A. The auxiliary agent is prepared by mixing boric acid ester coupling agent PCR-100, stearic acid amide, and composite acicular powder in a weight ratio of 3:1:6.

Embodiment 2

[0026] Antirust masterbatch 2 suitable for various metal surfaces and their coatings, wherein the weight ratio of each component is 40% antirust agent, 40% carrier plastic and 20% additives. Among them, the antirust agent is made by mixing imidazole acetate, 1H-1,2,4-triazole, and sodium molybdate in a weight ratio of 1.2:0.9:2.8, and the particle size of the antirust agent is 900-1100 mesh. The carrier plastic is high pressure low density polyethylene 1C7A. The auxiliary agent is prepared by mixing boric acid ester coupling agent PCR-100, stearic acid amide, and composite acicular powder in a weight ratio of 2.9:1.1:5.9.

Abstract

The invention discloses an antirust master batch applicable to various metallic surfaces and coating and plating layers of the metallic surfaces and preparation and application methods. The antirust master batch comprises components by weight: 40-45% of antirusting agent, 40-45% of carrier plastic and 10-20% of accessory ingredient. The antirusting agent is mixed by acetic acid imidazole, 1H-1,2,4-tolyltriazole and sodium molybdate according to the weight ratio of 1-1.2:0.9-1.3:2.8-3.5, and an accessory ingredient is mixed by boric acid ester, stearic acid amide and coarse whiting according to the weight ratio of 2.9-3.2:0.8-1.1:5.7-6.3. The antirust master batch is less in using amount, low in cost, capable of having antirust action on basic metal such as steel, copper, aluminum and magnesium and capable of adapting to antirust packaging of galvanization, tinning, oriented silicon steel, non-oriented silicon steel and the like.

Description

technical field [0001] The invention relates to the field of vapor phase antirust plastic products, in particular to an antirust masterbatch suitable for various metal surfaces and coatings thereof, and a preparation and application method thereof. Background technique [0002] Gas phase antirust plastic products are a kind of gas phase antirust material with polymer resin as the carrier of gas phase corrosion inhibitor. Its main forms include gas phase antirust plastic film, gas phase antirust tape, gas phase antirust plastic packaging bag, gas phase antirust Shrink film and other products are widely used in metallurgy, automobiles, electronic appliances, mechanical parts, military industry and other fields. The antirust effect of gas-phase anti-rust plastic products on metal is the synergistic result of the effective adsorption of gas-phase corrosion inhibitors contained in plastic products to metal surfaces and the shielding effect of plastic products on the ambient atmos...
