Problems solved by technology

[0003] Most commercially available vapor phase antirust sheets use wool felt or fiber as the carrier matrix, and dissolve the antirust agent and infiltrate and absorb it. The high concentration antirust agent can replenish the antirust gas in time during the long-term storage process; but such products It is easy to drop powdered medicine or fiber, which has the disadvantage of polluting the workpiece

Embodiment 1

[0023] Example 1 A rust-proof card and its preparation method

[0024] A gas phase antirust card, which includes the following raw materials in parts by weight:

[0025] 50g of LDPE, 25g of LLDPE, 6.36g of phosphoric acid, 7.63g of cyclohexylamine, 4g of sodium benzoate, and 4g of sodium molybdate.

[0026] A kind of preparation method of above-mentioned vapor phase antirust card, it carries out according to following order:

[0027] 1) Preparation of cyclohexylamine phosphate

[0028] Phosphoric acid and cyclohexylamine are mixed according to a mass ratio of 1:1.2 to obtain cyclohexylamine phosphate powder;

[0029] 2) Preparation of vapor phase rust inhibitor

[0030] Stir and mix the cyclohexylamine phosphate powder prepared above with sodium benzoate and sodium molybdate to finally obtain a gas-phase rust inhibitor;

[0031] 3) Preparation of vapor phase antirust card

[0032] Divide the vapor phase rust inhibitor into 3 parts, two of which are mixed with LDPE, and on...

Embodiment 2-6

[0036] Embodiment 2-6 Vapor phase anti-rust card and preparation method thereof

[0037] Examples 2-6 are a kind of vapor phase antirust card and its preparation method, wherein the preparation raw materials are similar to the preparation method, the only difference is that the amount of raw materials is different from the technical parameters involved in the preparation method, as shown in the following table Shown:

[0038]

[0039]

[0040] The vapor phase anti-rust cards prepared in Examples 2-6 are moderately soft and hard, not easily deformed and broken, and the anti-rust time in a closed space can reach more than 2 years.

Abstract

The invention discloses a rust prevention card and a preparation method thereof. Phosphate cyclohexylamine, sodium molybdate and other raw materials are adopted for being subjected to crosslinking coupling with low-density and low-pressure polyethylene and low-density and high-pressure polyethylene, rust prevention gas is released, and thus a very good rust prevention effect is achieved. A three-layer co-extrusion method is used in the preparation method of the rust prevention card, high-density polyethylene is placed on an upper layer and a lower layer, and the low-density polyethylene is placed on a middle layer. The prepared rust prevention card achieves perfect balance between hardness and softness and not liable to deformation or fracture. The preparation method is suitable for preparation of the rust prevention card, and the rust prevention card is suitable for rust prevention of any products.

Description

technical field [0001] The invention belongs to the field of antirust, and relates to an antirust card and a preparation method thereof, in particular to a gas phase antirust sheet and a preparation method thereof. Background technique [0002] With the length of the anti-rust period of the product and the application of anti-rust products, the anti-rust packaging materials also change. Most of the commercially available anti-rust packaging materials use sodium nitrite to control the characteristics of moisture and oxygen to achieve anti-rust and anti-oxidation effects, but sodium nitrite does not have the effect of vapor phase anti-rust. When metal products require a long anti-rust period, it is very important to maintain the effective concentration of the gas-phase anti-rust and anti-corrosion agent in the packaging space for a long time. The gas-phase anti-rust sheet can replenish the anti-rust gas in time. [0003] Most commercially available vapor phase antirust sheets...
